A lean hylomorphism stands as a metaphysical holy grail. An embarrassing feature of traditional hylomorphic ontologies is prime matter. Prime matter is both so basic that it cannot be examined (in principle) and its engagement with the other hylomorphic elements is far from clear. One particular problem posed by prime matter is how it is to be understood both as a principle of individuation for material substances and as pure potency. I present Thomas Aquinas’s way of squeezing (...) some intelligibility out of prime matter by modeling it on the idea of logical genus. Such a modeling provides insight into understanding prime matter as substratum, as maximally indeterminate, and as ontologically vague. One of the unusual but exciting things that fall out from this analysis of prime matter is the Entirety Thesis: “For any substance x, if x has prime matter then the prime matter of x is the same* as x,” where ‘same*’ is understood as “indeterminately identical.”.

Few notions are more central to Aquinas’s thought than those of matter and form. Although he invokes these notions in a number of different contexts, and puts them to a number of different uses, he always assumes that in their primary or basic sense they are correlative both with each other and with the notion of a “hylomorphic compound”—that is, a compound of matter (hyle) and form (morphe). Thus, matter is an entity that can have form, form is an entity (...) that can be had by matter, and a hylomorphic compound is an entity that exists when the potentiality of some matter to have form is actualized.1 What is more, Aquinas assumes that the matter of a hylomorphic compound explains certain of its general characteristics, whereas its form explains certain of its more specific characteristics. Thus, the matter of a bronze statue explains the fact that it is bronze, whereas its form explains the fact that it is a statue. Again, the matter of a human being explains the fact that it is a material object, whereas its form explains the specific type of material object it is (namely, human). My aim in this chapter is to provide a systematic introduction to Aquinas’s primary or basic notions of matter and form. To accomplish this aim, I focus on the two main theoretical contexts in which he deploys them—namely, his theory of change and his theory of individuation. In both contexts, as we shall see, Aquinas appeals to matter and form to account for relations of sameness and difference holding between distinct individuals. (shrink)

Identity-Over-Time has been a favorite subject in the literature concerning Thomas Aquinas. Aquinas addresses this issue in many discussions, including especially the identity of material things and artifacts, the identity of the human soul after the corruption of body, the identity of the body of Christ in the three days from his death to his resurrection and the identity of the resurrected human body at the end of time. All these discussions have a point in common: they lead Aquinas to (...) raise the question of Identity-Over-Time with respect to things that fully exist in act, i.e., things that possess an identity of their own and change some of their parts or properties over time while continuing to be what they are. In this article, I investigate this topic from a different angle, considering the case of the trans-temporal identity of things that do not yet have an identity of their own or fully exist in act. The case at stake is that of the identity of the human embryo through the process of human generation. It is a puzzle that Aquinas seems to have some difficulties to solving, given his account of human embryogenesis as a process that alternates generations and corruptions of the subject. At the same time, though, Aquinas does not want to renounce the idea that the subject of generation must be numerically one and the same throughout all the process. In order to solve this puzzle, Aquinas seems to suggest distinguishing the identity of the subject from the identity of its matter and/or form. At given conditions, a thing can even change its matter and form while continuing to be the same thing in number. Specifically, the numerical identity of the subject of generation is justified by the identity entailed by the metaphysical notions of potency and act. (shrink)

In this paper I argue that both defence and criticism of the claim that humans act ‘under the guise of the good’ neglects the metaphysical roots of the theory. I begin with an overview of the theory and its modern commentators, with critics noting the apparent possibility of acting against the good, and supporters claiming that such actions are instances of error. These debates reduce the ‘guise of the good’ to a claim about intention and moral action, and in so (...) doing have become divorced from the theory's roots in classical and medieval philosophy. Aristotle and Aquinas’ ‘guise of the good’ is primarily a metaphysical claim resting on the equivalence between actuality and goodness, from which conclusions about moral action are derived. I show the reasoning behind their theory and how it forms the basis for the claims about intention and action at the centre of the modern debate. Finally, I argue that the absence of its original foundation is apparent in recent attacks on the ‘guise of the good’. It is unsurprising that modern action theory and ethics have not always been able to comfortably accommodate the ‘guise of the good’; they are only telling half of the story. (shrink)

Holobionts are symbiotic assemblages composed by a host plus its microbiome. The status of holobionts as individuals has recently been a subject of continuous controversy, which has given rise to two main positions: on the one hand, holobiont advocates argue that holobionts are biological individuals; on the other, holobiont detractors argue that they are just mere chimeras or ecological communities, but not individuals. Both parties in the dispute develop their arguments from the framework of the philosophy of biology, in terms (...) of what it takes for a “conglomerate” to be considered an interesting individual from a biological point of view. However, the debates about holobiont individuality have important ontological implications that have remained vaguely explored from a metaphysical framework. The purpose of this paper is to cover that gap by presenting a metaphysical approach to holobionts individuality. Drawing upon a conception of natural selection that puts the focus on the transgenerational recurrence of the traits and that supports the thesis that holobionts are units of selection, we argue that holobionts bear emergent traits and exert downward powers over the entities that compose them. In this vein, we argue, a reasonable argument can be made for conceiving holobionts as emergent biological individuals. (shrink)

continent. 1.1 : 3-13. / 0/ – Introduction I want to propose, as a trajectory into the philosophically weird, an absurd theoretical claim and pursue it, or perhaps more accurately, construct it as I point to it, collecting the ground work behind me like the Perpetual Train from China Mieville's Iron Council which puts down track as it moves reclaiming it along the way. The strange trajectory is the following: Kant's critical philosophy and much of continental philosophy which has followed, (...) has been a defense against horror and madness. Kant's prohibition on speculative metaphysics such as dogmatic metaphysics and transcendental realism, on thinking beyond the imposition of transcendental and moral constraints, has been challenged by numerous figures proceeding him. One of the more interesting critiques of Kant comes from the mad black Deleuzianism of Nick Land stating, “Kant’s critical philosophy is the most elaborate fit of panic in the history of the Earth.” And while Alain Badiou would certainly be opposed to the libidinal investments of Land's Deleuzo-Guattarian thought, he is likewise critical of Kant's normative thought-bureaucracies: Kant is the one author for whom I cannot feel any kinship. Everything in him exasperates me, above all his legalism—always asking Quid Juris? Or ‘Haven’t you crossed the limit?’—combined, as in today’s United States, with a religiosity that is all the more dismal in that it is both omnipresent and vague. The critical machinery he set up has enduringly poisoned philosophy, while giving great succour to the academy, which loves nothing more than to rap the knuckles of the overambitious [….] That is how I understand the truth of Monique David-Menard’s reflections on the properly psychotic origins of Kantianism. I am persuaded that the whole of the critical enterprise is set up to to shield against the tempting symptom represented by the seer Swedenborg, or against ‘diseases of the head’, as Kant puts it. An entire nexus of the limits of reason and philosophy are set up here, namely that the critical philosophy not only defends thought from madness, philosophy from madness, and philosophy from itself, but that philosophy following the advent of the critical enterprise philosophy becomes auto-vampiric; feeding on itself to support the academy. Following Francois Laruelle's non-philosophical indictment of philosophy, we could go one step further and say that philosophy operates on the material of what is philosophizable and not the material of the external world. [1] Beyond this, the Kantian scheme of nestling human thinking between our limited empirical powers and transcendental guarantees of categorical coherence, forms of thinking which stretch beyond either appear illegitimate, thereby liquefying both pre-critical metaphysics and the ravings of the mad in the same critical acid. In rejecting the Kantian apparatus we are left with two entities – an unsure relation of thought to reality where thought is susceptible to internal and external breakdown and a reality with an uncertain sense of stability. These two strands will be pursued, against the sane-seal of post-Kantian philosophy by engaging the work of weird fiction authors H.P. Lovecraft and Thomas Ligotti. The absolute inhumanism of the formers universe will be used to describe a Shoggothic Materialism while the dream worlds of the latter will articulate the mad speculation of a Ventriloquil Idealism. But first we must address the relation of philosophy to madness as well as philosophy to weird fiction. /1/ – Philosophy and Madness There is nothing that the madness of men invents which is not either nature made manifest or nature restored. Michel Foucault. Madness and Civilization. The moment I doubt whether an event that I recall actually took place, I bring the suspicion of madness upon myself: unless I am uncertain as to whether it was not a mere dream. Arthur Schopenhauer. The World as Will and Idea, Vol. 3. Madness is commonly thought of as moving through several well known cultural-historical shifts from madness as a demonic or otherwise theological force, to rationalization, to medicalization psychiatric and otherwise. Foucault's Madness and Civilization is well known for orientating madness as a form of exclusionary social control which operated by demarcating madness from reason. Yet Foucault points to the possibility of madness as the necessity of nature at least prior to the crushing weight of the church. Kant’s philosophy as a response to madness is grounded by his humanizing of madness itself. As Adrian Johnston points out in the early pages of Time Driven pre-Kantian madness meant humans were seized by demonic or angelic forces whereas Kantian madness became one of being too human. Madness becomes internalized, the external demonic forces become flaws of the individual mind. Foucault argues that, while madness is de-demonized it is also dehumanized during the Renaissance, as madmen become creatures neither diabolic nor totally human reduced to the zero degree of humanity. It is immediately clear why for Kant, speculative metaphysics must be curbed – with the problem of internal madness and without the external safeguards of transcendental conditions, there is nothing to formally separate the speculative capacities for metaphysical diagnosis from the mad ramblings of the insane mind – both equally fall outside the realm of practicality and quotidian experience. David-Menard's work is particularly useful in diagnosing the relation of thought and madness in Kant's texts. David-Menard argues that in Kant's relatively unknown “An Essay on the Maladies of the Mind” as well as his later discussion of the Seer of Swedenborg, that Kant formulates madness primarily in terms of sensory upheaval or other hallucinatory theaters. She writes: “madness is an organization of thought. It is made possible by the ambiguity of the normal relation between the imaginary and the perceived, whether this pertains to the order of sensation or to the relations between our ideas” Kant's fascination with the Seer forces Kant between the pincers of “aesthetic reconciliation” – namely melancholic withdrawal – and “a philosophical invention” – namely the critical project. Deleuze and Guattari's schizoanalysis is a combination and reversal of Kant's split, where an aesthetic over engagement with the world entails prolific conceptual invention. Their embrace of madness, however, is of course itself conceptual despite all their rhizomatic maneuvers. Though they move with the energy of madness, Deleuze and Guattari save the capacity of thought from the fangs of insanity by imbuing materiality itself with the capacity for thought. Or, as Ray Brassier puts it, “Deleuze insists, it is necessary to absolutize the immanence of this world in such a way as to dissolve the transcendent disjunction between things as we know them and as they are in themselves”. That is, whereas Kant relied on the faculty of judgment to divide representation from objectivity Deleuze attempts to flatten the whole economy beneath the juggernaut of ontological univocity. Speculation, as a particularly useful form of madness, might fall close to Deleuze and Guattari’s shaping of philosophy into a concept producing machine but is different in that it is potentially self destructive – less reliant on the stability of its own concepts and more adherent to exposing a particular horrifying swath of reality. Speculative madness is always a potential disaster in that it acknowledges little more than its own speculative power with the hope that the gibbering of at least a handful of hysterical brains will be useful. Pre-critical metaphysics amounts to madness, though this may be because the world itself is mad while new attempts at speculative metaphysics, at post-Kantian pre-critical metaphysics, are well aware of our own madness. Without the sobriety of the principle of sufficient reason we have a world of neon madness: “we would have to conceive what our life would be if all the movements of the earth, all the noises of the earth, all the smells, the tastes, all the light – of the earth and elsewhere, came to us in a moment, in an instant – like an atrocious screaming tumult of things”. Speculative thought may be participatory in the screaming tumult of the world or, worse yet, may produce its spectral double. Against theology or reason or simply commonsense, the speculative becomes heretical. Speculation, as the cognitive extension of the horrorific sublime should be met with melancholic detachment. Whereas Kant's theoretical invention, or productivity of thought, is self -sabotaging, since the advent of the critical project is a productivity of thought which then delimits the engine of thought at large either in dogmatic gestures or non-systematizable empirical wondrousness. The former is celebrated by the fiction of Thomas Ligotti whereas the latter is espoused by the tales of H.P. Lovecraft. /2/ – Weird Fiction and Philosophy. Supernatural horror, in all its eerie constructions, enables a reader to taste treats inconsistent with his personal welfare. Thomas Ligotti Songs of a Dead Dreamer. I choose weird stories because they suit my inclination best—one of my strongest and most persistent wishes being to achieve,momentarily, the illusion of some strange suspension or violation of the galling limitations of time, space, and natural law which forever imprison us and frustrate our curiosity about the infinite cosmic spaces beyond the radius of our sight and analysis H.P. Lovecraft. “Notes on Writing Weird Fiction” Lovecraft states that his creation of a story is to suspend natural law yet, at the same time, he indexes the tenuousness of such laws, suggesting the vast possibilities of the cosmic. The tension that Lovecraft sets up between his own fictions and the universe or nature is reproduced within his fictions in the common theme of the unreliable narrator; unreliable precisely because they are either mad or what they have witnessed questions the bounds of material reality. In “The Call of Cthulhu” Lovecraft writes: The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace and safety of a new dark age. Despite Lovecraft's invocations of illusion, he is not claiming that his fantastic creations such as the Old Ones are supernatural but, following Joshi, are only ever supernormal. One can immediately see that instead of nullifying realism Lovecraft in fact opens up the real to an unbearable degree. In various letters and non-fictional statements Lovecraft espoused strictly materialist tenets, ones which he borrowed from Hugh Elliot namely the uniformity of law, the denial of teleology and the denial of non-material existence. Lovecraft seeks to explore the possibilities of such a universe by piling horror upon horror until the fragile brain which attempts to grasp it fractures. This may be why philosophy has largely ignored weird fiction – while Deleuze and Guattari mark the turn towards weird fiction and Lovecraft in particular, with the precursors to speculative realism as well as contemporary related thinkers have begun to view Lovecraft as making philosophical contributions. Lovecraft's own relation to philosophy is largely critical while celebrating Nietzsche and Schopenhauer. This relationship of Lovecraft to philosophy and philosophy to Lovecraft is coupled with Lovecraft's habit of mercilessly destroying the philosopher and the figure of the academic more generally in his work, a destruction which is both an epistemological destruction and an ontological destruction. Thomas Ligotti's weird fiction which he has designated as a kind of “confrontational escapism” might be best described in the following quote from one of his shortstories, “The human phenomenon is but the sum of densely coiled layers of illusion each of which winds itself on the supreme insanity. That there are persons of any kind when all there can be is mindless mirrors laughing and screaming as they parade about in an endless dream”. Whereas Lovecraft's weirdness draws predominantly from the abyssal depths of the uncharted universe, Ligotti's existential horror focuses on the awful proliferation of meaningless surfaces that is, the banal and every day function of representation. In an interview, Ligotti states: We don't even know what the world is like except through our sense organs, which are provably inadequate. It's no less the case with our brains. Our whole lives are motored along by forces we cannot know and perceptions that are faulty. We sometimes hear people say that they're not feeling themselves. Well, who or what do they feel like then? This is not to say that Ligotti sees nothing beneath the surface but that there is only darkness or blackness behind it, whether that surface is on the cosmological level or the personal. By addressing the implicit and explicit philosophical issues in Ligotti's work we will see that his nightmarish take on reality is a form of malevolent idealism, an idealism which is grounded in a real, albeit dark and obscure materiality. If Ligotti's horrors ultimately circle around mad perceptions which degrade the subject, it takes aim at the vast majority of the focus of continental philosophy. While Lovecraft's acidic materialism clearly assaults any romantic concept of being from the outside, Ligotti attacks consciousness from the inside: Just a little doubt slipped into the mind, a little trickle of suspicion in the bloodstream, and all those eyes of ours, one by one, open up to the world and see its horror [...] Not even the solar brilliance of a summer day will harbor you from horror. For horror eats the light and digests it into darkness. Clearly, the weird fiction of Lovecraft and Ligotti amount to a anti-anthrocentric onslaught against the ramparts of correlationist continental philosophy. /3/ – Shoggothic Materialism or the Formless Formless protoplasm able to mock and reflect all forms and organs and processes—viscous agglutinations of bubbling cells—rubbery fifteen-foot spheroids infinitely plastic and ductile—slaves of suggestion, builders of cities—more and more sullen, more and more intelligent, more and more amphibious, more and more imitative—Great God! What madness made even those blasphemous Old Ones willing to use and to carve such things? H.P. Lovecraft. “At the Mountains of Madness” On the other hand, affirming that the universe resembles nothing and is only formless amounts to saying that the universe is something like a spider or spit. Georges Bataille. “Formless”. The Shoggoths feature most prominently in H.P. Lovecraft's shortstory “At the Mountains of Madness” where they are described in the following manner: It was a terrible, indescribable thing vaster than any subway train – a shapeless congeries of protoplasmic bubbles, faintly self -luminous, and with myriads of temporary eyes forming and un-forming as pustules of greenish light all over the tunnel-filling front that bore down upon us, crushing the frantic penguins and slithering over the glistening floor that it and its kind had swept so evilly free of all litter. The term is a litmus test for materialism itself as the Shoggoth is an amorphous creature. The Shoggoths were living digging machines bio engineered by the Elder Things, and their protoplasmic bodies being formed into various tools by their hypnotic powers. The Shoggoths eventually became self aware and rose up against their masters in an ultimately failed rebellion. After the Elder Ones retreated into the oceans leaving the Shoggoths to roam the frozen wastes of the Antarctic. The onto-genesis of the Shoggoths and their gross materiality, index the horrifyingly deep time of the earth a concept near and dear to Lovecraft's formulation of horror as well as the fear of intelligences far beyond, and far before, the ascent of humankind on earth and elsewhere. The sickly amorphous nature of the Shoggoths invade materialism at large, where while materiality is unmistakably real ie not discursive, psychological, or otherwise overly subjectivist, it questions the relation of materialism to life. As Eugene Thacker writes: The Shoggoths or Elder Things do not even share the same reality with the human beings who encounter them—and yet this encounter takes place, though in a strange no-place that is neither quite that of the phenomenal world of the human subject or the noumenal world of an external reality. Amorphous yet definitively material beings are a constant in Lovecraft's tales. In his tale “The Dream-Quest of Unknown Kadatth” Lovecraft describes Azathoth as, “that shocking final peril which gibbers unmentionably outside the ordered universe,” that, “last amorphous blight of nethermost confusion which blashphemes and bubbles at the centre of all infinity,” who, “gnaws hungrily in inconceivable, unlighted chambers beyond time”. Azathoth's name may have multiple origins but the most striking is the alchemy term azoth which is both a cohesive agent and a acidic creation pointing back to the generative and the decayed. The indistinction of generation and degradation materially mirrors the blur between the natural and the unnatural as well as life and non-life. Lovecraft speaks of the tension between the natural and the unnatural is his short story “The Unnameable.” He writes, “if the psychic emanations of human creatures be grotesque distortions, what coherent representation could express or portray so gibbous and infamous a nebulousity as the spectre of a malign, chaotic perversion, itself a morbid blasphemy against Nature?”. Lovecraft explores exactly the tension outlined at the beginning of this chapter, between life and thought. At the end of his short tale Lovecraft compounds the problem as the unnameable is described as “a gelatin—a slime—yet it had shapes, a thousand shapes of horror beyond all memory”. Deleuze suggests that becoming-animal is operative throughout Lovecraft's work, where narrators feel themselves reeling at their becoming non-human or of being the anomalous or of becoming atomized. Following Eugene Thacker however, it may be far more accurate to say that Lovecraft's tales exhibit not a becoming-animal but a becoming-creature. Where the monstrous breaks the purportedly fixed laws of nature, the creature is far more ontologically ambiguous. The nameless thing is an altogether different horizon for thought. The creature is either less than animal or more than animal – its becoming is too strange for animal categories and indexes the slow march of thought towards the bizarre. This strangeness is, as aways, some indefinite swirling in the category of immanence and becoming. Bataille begins “The Labyrinth” with the assertion that being, to continue to be, is becoming. More becoming means more being hence the assertion that Bataille's barking dog is more than the sponge. This would mean that the Shoggotth is altogether too much being, too much material in the materialism. Bataille suggests that there is an immanence between the eater and the eaten, across the species and never within them. That is, despite the chaotic storm of immanence there must remain some capacity to distinguish the gradients of becoming without reliance upon, or at least total dependence upon, the powers of intellection to parse the universe into recognizable bits, properly digestible factoids. That is, if we undo Deleuze's aforementioned valorization of sense which, for his variation of materialism, performed the work of the transcendental, but refuse to reinstate Kant's transcendental disjunction between thing and appearance, then it must be a quality of becoming-as-being itself which can account for the discernible nature of things by sense. In an interview with Peter Gratton, Jane Bennett formulates the problem thusly: What is this strange systematicity proper to a world of Becoming? What, for example, initiates this congealing that will undo itself? Is it possible to identify phases within this formativity, plateaus of differentiation? If so, do the phases/plateaus follow a temporal sequence? Or, does the process of formation inside Becoming require us to theorize a non-chronological kind of time? I think that your student’s question: “How can we account for something like iterable structures in an assemblage theory?” is exactly the right question. Philosophy has erred too far on the side of the subject in the subject-object relation and has furthermore, lost the very weirdness of the non-human. Beyond this, the madness of thought need not override. /4/ - Ventriloquial Idealism or the Externality of Thought My aim is the opposite of Lovecraft's. He had an appreciation for natural scenery on earth and wanted to reach beyond the visible in the universe. I have no appreciation for natural scenery and want the objective universe to be a reflection of a character. Thomas Ligotti. “Devotees of Decay and Desolation.” Unless life is a dream, nothing makes sense. For as a reality, it is a rank failure [….] Horror is more real than we are. Thomas Ligotti. “Professor Nobody's Little Lectures on Supernatural Horror”. Thomas Ligotti's tales are rife with mannequins, puppets, and other brainless entities which of replace the valorized subject of philosophy – that of the free thinking human being. His tales such as “The Dream of the Manikin” aim to destroy the rootedness of consciousness. James Trafford has connected the anti-egoism of Ligotti to Thomas Metzinger – where the self is at best an illusion and we plead desperately for someone else to acknowledge that we are real. Trafford has stated it thus, “Life is played out as an inescapable puppet show, an endless dream in which the puppets are generally unaware that they are trapped within a mesmeric dance of whose mechanisms they know nothing and over which they have no control”. An absolute materialism, for Ligotti, implies an alienation of the idea which leads to a ventriloquil idealism. As Ligotti notes in an interview, “the fiasco and nightmare of existence, the particular fiasco and nightmare of human existence, the sense that people are puppets of powers they cannot comprehend, etc.” And then further elaborates that,“[a]ssuming that anything has to exist, my perfect world would be one in which everyone has experienced the annulment of his or her ego. That is, our consciousness of ourselves as unique individuals would entirely disappear”. The externality of the idea leads to the unfortunate consequence of consciousness eating at itself through horror which, for Ligotti, is more real than reality and goes beyond horror-as-affect. Beyond this, taking together with the unreality of life and the ventriloquizing of subjectivity, Ligotti's thought becomes an idealism in which thought itself is alien and ultimately horrifying. The role of human thought and the relation of non-relation of horror to thought is not completely clear in Ligotti's The Conspiracy Against the Human Race. Ligotti argues in his The Conspiracy Against the Human Race,that the advent of thought is a mistake of nature and that horror is being in the sense that horror results from knowing too much. Yet, at the same time, Ligotti seems to suggest that thought separates us from nature whereas, for Lovecraft, thought is far less privileged – mind is just another manifestation of the vital principal, it is just another materialization of energy. In his brilliant “Prospects for Post-Copernican Dogmatism” Iain Grant rallies against the negative definition of dogmatism and the transcendental, and suggests that negatively defining both over-focuses on conditions of access and subjectivism at the expense of the real or nature. With Schelling, who is Grant's champion against the subjectivist bastions of both Fichte and Kant, Ligotti's idealism could be taken as a transcendental realism following from an ontological realism. Yet the transcendental status of Ligotti's thought move towards a treatment of the transcendental which may threaten to leave beyond its realist ground. Ligotti states: Belief in the supernatural is only superstition. That said, a sense of the supernatural, as Conrad evidenced in Heart of Darkness, must be admitted if one's inclination is to go to the limits of horror. It is the sense of what should not be- the sense of being ravaged by the impossible. Phenomenally speaking, the super-natural may be regarded as the metaphysical counterpart of insanity, a transcendental correlative of a mind that has been driven mad. Again, Ligotti equates madness with thought, qualifying both as supernatural while remaining less emphatic about the metaphysical dimensions of horror. The question becomes one of how exactly the hallucinatory realm of the ideal relates to the black churning matter of Lovecraft's chaos of elementary particles. In his tale “I Have a Special Plan for This World” Ligotti formulates thus: A: There is no grand scheme of things. B: If there were a grand scheme of things, the fact – the fact – that we are not equipped to perceive it, either by natural or supernatural means, is a nightmarish obscenity. C: The very notion of a grand scheme of things is a nightmarish obscenity. Here Ligotti is not discounting metaphysics but implying that if it does exist the fact that we are phenomenologically ill-equipped to perceive that it is nightmarish. For Ligotti, nightmare and horror occur within the circuit of consciousness whereas for Lovecraft the relation between reality and mind is less productive on the side of mind. It is easier to ascertain how the Kantian philosophy is a defense against the diseases of the head as Kant armors his critical enterprise from too much of the world and too much of the mind. The weird fiction of both Lovecraft and Ligotti demonstrates that there is too much of both feeding into one another in a way that corrodes the Kantian schema throughly, breaking it down into a dead but still ontologically potentiated nigredo. The haunting, terrifying fact of Ligotti's idealism is that the transcendental motion which brought thought to matter, while throughly material and naturalized, brings with it the horror that thought cannot be undone without ending the material that bears it either locally or completely. Thought comes from an elsewhere and an elsewhen being-in-thought. The unthinkable outside thought is as maddening as the unthought engine of thought itself within thought which doesn't exist except for the mind, the rotting décor of the brain. /5/ - Hyperstitional Transcendental Paranoia or Self -Expelled Thought Weird fiction has been given some direct treatment in philosophy in the mad black Deleuzianism of Nick Land. Nick Land along with others in the 1990s created the Cyber Culture Research Unit as well as the research group Hyperstition. The now defunct hyperstitional website, an outgrowth of the Cyber Culture Research Unit, defined hyperstition in the following fourfold: 1-Element of effective culture that makes itself real. 2-Fictional quantity functional as a time-traveling device. 3-Coincidence intensifier. 4-Call to the Old Ones. The distinctively Lovecraftian character of hyperstition is hard to miss as is its Deleuzo-Guattarian roots. In the opening pages of A Thousand Plateaus Deleuze and Guattari write, “We have been criticized for over-quoting literary authors. But when one writes, the only question is which other machine the literary machine can be plugged into”. The indisinction of literature and philosophy mirrors the mess of being and knowing as post-correlationist philosophy, where philosophy tries to make itself real where literature, especially the weird, aims itself at the brain-circuit of horror. The texts of both Lovecraft and Ligotti work through horror as epistemological plasticity meeting with proximity as well as the deep time of Lovecraft and the glacially slow time of paranoia in Ligotti. Against Deleuze, and following Brassier, we cannot allow the time of consciousness, the Bergsonian time of the duree, to override natural time, but instead acknowledge that it is an unfortunate fact of existence as a thinking being. Horror-time, the time of consciousness, with all its punctuated moments and drawn out terrors, cannot compare to the deep time of non-existence both in the unreachable past and the unknown future. The crystalline cogs of Kant's account of experience as the leading light for the possibility of metaphysics must be throughly obliterated. His gloss of experience in Prolegomena to any Future Metaphysics could not be more sterile: Experience consists of intuitions, which belong to the sensibility, and of judgments, which are entirely a work of the understanding. But the judgments which the understanding makes entirely out of sensuous intuitions are far from being judgments of experience. For in the one case the judgment connects only the perceptions as they are given in sensuous intuition [....] Experience consists in the synthetic connection of appearances in consciousness, so far as this connection is necessary. Here it is difficult to dismiss the queasiness that Kant's legalism induces upon sight for both Badiou and David-Menard. Kant's thought becomes, as Foucault says when reflecting on Sade's text in relation to nature, “the savage abolition of itself”. For Badiou, Kant's philosophy simply closes off too much of the outside, freezing the world of thought in an all too limited formalism. Critical philosophy is simply the systematized quarantine on future thinking, on thinking which would threaten the formalism which artificially grants thought its own coherency in the face of madness. Even the becoming-mad of Deleuze, while escaping the rumbling ground, makes grounds for itself, mad grounds but grounds which are thinkable in their affect. The field of effects allows for Deleuze's aesthetic and radical empiricism, in which effects and/or occasions make up the material of the world to be thought as a chaosmosis of simulacra. Given a critique of an empiricism of aesthetics, of the image, it may be difficult to justify an attack on Kantian formalism with the madness of literature, which does not aim to make itself real but which we may attempt to make real. That is, how do Lovecraft's and Ligotti's materials, as materials for philosophy to work on, differ from either the operative formalisms of Kant or the implicitly formalized images of Deleuzian empiricism? It is simply that such texts do not aim to make themselves real, and make claims to the real which are more alien to us than familiar, which is why their horror is immediately more trustworthy. This is the madness which Blanchot discusses in The Infinite Conversation through Cervantes and his knight – the madness of book-life, of the perverse unity of literature and life a discussion which culminates in the discussion of one of the weird's masters, that of Kafka. The text is the knowing of madness, since madness, in its moment of becoming-more-mad, cannot be frozen in place but by the solidifications of externalizing production. This is why Foucault ends his famous study with works of art. Furthermore extilligence, the ability to export the products of our maligned brains, is the companion of the attempts to export, or discover the possibility of intelligences outside of our heads, in order for philosophy to survive the solar catastrophe. To borrow again from Deleuze, writing is inseparable from becoming. The mistake is to believe that madness is reabsorbed by extilligence, by great works, or that it could be exorcised by the expelling of thought into the inorganic or differently organic. Going out of our heads does not guarantee we will no longer mean we cannot still go out of our minds. This is simply because of the outside, of matter, or force, or energy, or thing-in-itself, or Schopenhauerian Will. In Lovecraft’s “The Music of Erich Zahn” an “impoverished student of metaphysics” becomes intrigued by strange viol music coming from above his room. After meeting the musician the student discovers that each night he plays frantic music at a window in order to keep some horridness at bay, some “impenetrable darkness with chaos and pandemonium”. The aesthetic defenses provided by the well trained brain can bear the hex of matter for so long, the specter of unalterability within it which too many minds obliterate, collapsing everything before the thought of thought as thinkable or at least noetically mutable on our own terms. Transcendental paranoia is the concurrent nightmare and promise of Paul Humphrey's work, of being literally out of our minds. It is the gothic counterpart of thinking non-conceptually but also of thinking never belonging to any instance of purportedly solid being. As Bataille stated, “At the boundary of that which escapes cohesion, he who reflects within cohesion realizes there is no longer any room for him” Thought is immaterial only to the degree that it is inhuman, it is a power that tries, always with failure, to ascertain its own genesis. Philosophy, if it can truly return to the great outdoors, if it can leave behind the dead loop of the human skull, must recognize not only the non-priority of human thought, but that thought never belongs to the brain that thinks it, thought comes from somewhere else. To return to the train image from the beginning “a locomotive rolling on the surface of the earth is the image of continuous metamorphosis” this is the problem of thought, and of thinking thought, of being no longer able to isolate thought, with only a thought-formed structure. [1] One of the central tenets of Francois Laruelle's non-philosophy is that philosophy has traditionally operated on material already presupposed as thinkable instead of trying to think the real in itself. Philosophy, according to Laruelle, remains fixated on transcendental synthesis which shatters immanence into an empirical datum and an a prori factum which are then fused by a third thing such as the ego. For a critical account of Laruelle's non-philosophy see Ray Brassier's Nihil Unbound. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge Companion to OckhamJeffrey E. BrowerPaul Vincent Spade, editor. The Cambridge Companion to Ockham. Cambridge: Cambridge University Press, 1999. Pp. xii + 400. Cloth, $54.95.Contemporary analytic philosophers have always been among the most enthusiastic audiences for the volumes in the Cambridge Companion series. And of all the great philosophers of the Middle Ages, perhaps none has appealed more to their sensibilities than William Ockham. It is fitting, (...) therefore, that after the publication of the Companion to Aquinas—the first volume in the series devoted to a medieval philosopher—there should appear a Companion to Ockham.The fifteen chapters comprising this volume survey the entire range of Ockham's thought and may conveniently be divided into four main parts. The first part (chaps. 2-7) deals with Ockham's most enduring legacy: his contribution to issues falling within the domain of logic, philosophy of language, and metaphysics. The second part (chaps. 8-9) is devoted to issues in epistemology and philosophy of mind/cognition. The third part (chaps. 10-13) focuses on Ockham's views in ethics, action theory, and political philosophy. And the fourth part (chaps. 14-15) considers aspects of his philosophical theology. In addition, there is also an historical chapter (chap. 1), placing Ockham's life and works in their late-medieval intellectual context, and a brief editor's introduction, including a very useful list of all Ockham's writings, together with the best (sometimes, the only) Latin editions and English translations available.The volume is well organized and beautifully conceived. Some chapters are quite difficult, and in places contain material that is likely to be unfamiliar even to specialists in medieval philosophy. But the way in which they have been organized maximizes their usefulness and accessibility to specialists and non-specialists alike. The earlier parts of the volume lay the foundation for later ones, and the individual chapters within each part are arranged so as to build on and complement one another. This is perhaps most evident in the five chapters comprising the first part. Calvin Normore's presentation ofOckham's logic (in chap. 2) nicely prepares the reader for Claude Panaccio's discussion (in chap. 3) of Ockham's theory of mental language. Panaccio's chapter, in turn, provides the framework for David Chalmer's analysis (in chap. 4) of the debate over whether [End Page 588] Ockham's mental language permits synonymous expressions. Again, these three chapters taken together provide important background for Paul Spade's treatment (in chap. 5) of Ockham's views in metaphysics, which are closely related to his logic and philosophy of language. Finally, Gyula Klima's discussion (in chap. 6) ofhow Ockham's views in semantics and ontology differ from those of his predecessors, and André Goddu's discussion (in chap. 7) of Ockham's philosophy of nature, can be fully appreciated only against the background of the preceding chapters.What is perhaps most impressive about the volume, however, is the extent to which it succeeds at providing a systematic introduction to Ockham's philosophical achievement. All the chapters are, to some extent, concerned with matters of textual analysis and interpretation. But most of them involve much more than a mere survey of Ockham's texts. For example, in each of the four main parts, there is at least one chapter that attempts to locate Ockham's views in relation to those of his predecessors or contemporaries (such as Aquinas and Scotus), with the result that we get a sense of Ockham's place in the major medieval debates to which he contributed. At the same time, the volume introduces us to some of the most lively current debates in Ockham scholarship. It does this, not merely by summarizing them, but by actually carrying them out over the course of its chapters. For example, Eleonore Stump provides a sophisticated defense (in chap. 8) of what has become a standard interpretation of Ockham's theory of intuitive and abstractive cognition. In the following chapter, however, Elizabeth Karger rejects the standard interpretation on the basis of a re-reading of certain key texts. Again, in the first part of the volume there is a running debate... (shrink)

Thomas Aquinas embraces a controversial claim about the way in which parts of a substance depend on the substance’s substantial form. On his metaphysics, a ‘substantial form’ is not merely a relation among already existing things, in virtue of which (for example) the arrangement or configuration of those things would count as a substance. The substantial form is rather responsible for the identity or nature of the parts of the substance such a form constitutes. Aquinas’ controversial claim can be roughly (...) put as the view that things are members of their kind in virtue of their substantial form. To put it simply, Aquinas’ claim results in the implication that, every time the xs come to compose a y, those xs have to undergo a change in kind membership. -/- This has been called the “homonymy principle,” and it follows from Aquinas’ view of substantial forms, and specifically from the position that substantial forms inform prime matter, rather than substance-parts. The aim of this paper will be to defend that the Thomistic claim that substantial forms account for the determinate actuality of every part of a substance is plausible and coherent. After defending the Thomistic account, I propose that approaching problems of material composition as a Thomist has a significant, oft-overlooked advantage of involving a thorough-going naturalistic methodology that resolves such problems by appeal to empirical considerations.

The essay brings a summation of human efforts seeking to understand our existence. Plato and Kant & cognitive science complete reduction of philosophy to a neural mechanism, evolved along elementary Darwinian principles. Plato in his famous Cave Allegory explains that between reality and our experience of it there exists a great chasm, a metaphysical gap, fully confirmed through particle-wave duality of quantum physics. Kant found that we have two kinds of perception, two senses: By the spatial outer sense we perceive (...) phenomena, objects in space. Our temporal inner sense lets us perceive our inner state, noumena . Kant's two senses are fully confirmed through bilateral brain duality of cognitive science. The bilateral brain serves inner, temporal sense, logic & noumena in the left hemisphere. The right brain half is for the outer, spatial sense, geometry & phenomena. We form a whole system, a bilateral interior cosmos, a kind of world model, expressing what may lie beyond the metaphysical gap. In the right brain we build a phenomenal cosmos, to resemble the outer environment. In the brain's left hemisphere a noumenal cosmos, a model of our private world including Saint Teresa of Avila's castillo interior. The cosmos is regularly updated with novel sense data integrated into our memory banks. This was recognized early by Helmholtz (1860s). Our lives, health & well-being depend on us keeping our interior cosmos in good order. This used to be seen as saving one's precious soul from perdition. While we endeavour to keep our phenomenal cosmos neat & orderly by protecting the environment from harm, our noumenal cosmos to be livable requires us to engage in ethical conduct. This bilateral cosmos is responsible for our common sense judgment power, that we depend on for being able to lead a good & benign life. The 200 million neurons of BA10 in the prefrontal lobe have global access to the interior cosmos, & apply massive feedback to identify environmental conditions rapidly. The global access also gives conscious presence of the individual to itself, all that is present in the interior cosmos, for total freedom of action. In the left brain private ego, we are guarded by faith in divine mercy, & guided to choose the best course of action, able to survive under the most adverse conditions. For this, we receive directions from the Holy Ghost in Saint Teresa's castillo interior. (shrink)

The encounter of the medieval Muslims with Greek philosophy undeniably shaped the course of their philosophical and theological thought. This encounter led to the complex and contentious issue of ‘philosophy versus theology’. Medieval Muslim thinkers needed to develop a response to the issue of philosophy versus theology. The present article will first highlight the response of the Islamic theologians to their encounter with Greek philosophy in the form of three major trends in medieval Islamic theology: (1) strong (...) opposition to the application of reason and rationalist approach to Islamic doctrines, and strict adherence to the actual text of the Qur’an and the Hadith, (2) the adoption of Greek philosophy, and the application of reason and rationalist approach to explain and defend Islamic religion and (3) acknowledging the significance of reason in exploring the matters related to the natural world but, at the same time, stressing the subordination of reason to revelation. This article will discuss Atharism, Muʿtazilism and Ashʿarism as the representatives of the first, second and third trends, respectively. The response of the medieval Islamic theologians to the issue of philosophy versus theology serves as a context in which medieval Muslim philosophers carried out their philosophy–theology debate. The article will proceed to show that some medieval Muslim philosophers, such as Abu Bakr Al-Razi, subordinated religion or revelation to philosophy or reason. Other medieval Muslim philosophers, such as Al-Ghazali, subordinated philosophy to theology. The third group of medieval Islamic philosophers represented by Alfarabi argued for the reconciliation and harmonious co-existence of philosophy and religion. Contribution: This article highlights the response of medieval Islamic theologians and philosophers to the issue of philosophy versus theology that was caused by their encounter with Greek philosophy.

In this paper, we provide an account of the ontological status of Christ’s dead body, which remained in the tomb during the three days after his crucifixion. Our account holds that Christ’s dead body – during the time between his death and resurrection – was prime matter without a substantial form. We defend this account by showing how it is metaphysically possible for prime matter to exist in actuality without substantial forms. Our argument turns on the truth of (...) two theses: God is able to produce all acts of secondary causes without those secondary causes, and Substantial forms are secondary causes of the actuality of prime matter. We argue that the metaphysical possibility of matter without form is perfectly consistent with holding both there is only one substantial form in a material substance and that prime matter is pure potentiality. Moreover, we argue that the metaphysical possibility of matter without form does little-to-no damage to our natural understanding of material substances. (shrink)

Brian Leftow sets out to provide us with an account of Aquinas’s metaphysics of modality. Drawing on some important recent work, which is surely close to the spirit (if not quite the letter) of Aquinas’s thought, he frames his discussion in terms of “truthmakers”: what is it that makes true claims about possibility and necessity—that is to say, what serves as their ontological ground or ultimate metaphysical explanation? Leftow’s main thesis is that, for Aquinas, all true modal claims are made (...) true by one and the same thing—namely, God. Along the way, however, he also attempts to show that Aquinas’s endorsement of this thesis commits him to an objectionable form of Platonism about possible worlds. (shrink)

Between 1653 and 1655 Margaret Cavendish makes a radical transition in her theory of matter, rejecting her earlier atomism in favour of an infinitely-extended and infinitely-divisible material plenum, with matter being ubiquitously self-moving, sensing, and rational. It is unclear, however, if Cavendish can actually dispense of atomism. One of her arguments against atomism, for example, depends upon the created world being harmonious and orderly, a premise Cavendish herself repeatedly undermines by noting nature’s many disorders. I argue that her supposed difficulties (...) with atomism expose a deeper tension in her work between two fundamental metaphysical commitments each of which has substantial philosophical support: her monist theory of the material world (which maintains that there exists just one natural substance which is the single principal cause) and her occasional theory of causation (which requires multiple finite principal causes in nature -- causes that might be considered individual substances). Her monism undermines atomism while her theory of occasional cause seems to rest on a conception of nature that would be especially friendly to atomism. I argue further that we can solve this tension within a Cavendishian framework in such a way as to preserve her theory of causation and her monism, but that this solution depends upon our taking her monism in a particular (and weak) form. I finally note that we can best make sense of her unique and interesting form of monism by acknowledging her social-political motivations in addition to her motivations in natural philosophy.

Spinoza developed a highly interesting metaphysical theory of nature and individuality. In this paper, I endeavor to bring forward some ideas on how Spinozistic views on extended substance, physical world, and individuality can be approached using the concept of power as the basis of interpretation. Jonathan Bennett's ‘field metaphysical’ interpretation of Spinoza's doctrine of one extended substance has generated much discussion, and forms the other starting point of my paper. I believe that the field metaphysical interpretation enables one to deal (...) with the central questions concerning physical individuation — individuality and the persistence of individual being — in a rather novel way. My main question is this: what follows if physical individuals are seen as parts of a unified field of extended power? (shrink)

Practical research, according to Aristotle, strives to actualize the Supreme Good as the ultimate end of life. The Final Good could be determined if preceded by an outline based on conceptual analysis. For this reason, Aristotle considers agathón (ἀγαθόν), as the universal concept of good, and clarifies its conceptual-categorical structure to explain how we can understand it. In virtue of the similarity between good and existences for their extension of senses (good has as many meanings as existences), Aristotle proceeds to (...) analyze good compared to existence as an absolute philosophical conception. Alongside his comparative study of good and existence, we can consider a metaphysics for good similar to the metaphysics of being and question its possibility. Corresponding to the metaphysics of existence that considers being qua being, one can imagine a metaphysics for good that investigates goodness qua goodness and explores its philosophical characteristics and theoretical attributes aimed at the question of its possibility. It appears, in the process of Aristotle’s analysis that there is a common meaning and central definite characteristic in several significations and different categories of being by reference to one starting point: the primary being or substance. From the categorical point of view, similarly, various categories are accidental qualities of the fundamental category of substance. Because of the one principle of the primary being or substance, a metaphysics for being which contemplates on being qua being would be possible. But good, on the contrary, is used homonymously in various different senses without any common meaning and with no reference to one principle. Of the categorical attitude, good is applied in any individual category independently with no connection with each other and by no reference to one main category. There is not, in fact, any category of primary good or substantial good which constitutes universal meaning and a single category as an appropriate subject matter for the intended knowledge of the metaphysics of good. Consequently, it is not possible to establish one primary philosophy for goodness qua goodness in the same way as the first philosophy of being as being. Knowledge, according to Aristotle, is composed of the eidos (form or essence) as a universal absolute subject and eidetic attitude as a necessary theoretical way of understanding. Eidetic view and eidos entity are based on the common meaning and single principle which are not found in the concept of good. Thus, the theoretical approach to good, which could not constitute the eidos of good and eidetic knowledge, leads to the Platonic Idea of good and the dialectical attitude. But Aristotle who does not follow dialectic, cannot obtain the eidetic path to goodness either, and, therefore, reconstructs good as the well-being which is the final good that humankind can obtain practically. So he goes on to outline good not as the good in itself which in essence necessitates theoretical cognition, but as a final good of human life that is a condition that entails practical realization.

One big question in biology is what life is, but another is how life divides into living things. This is the problem of biological individuality. Proposed statements of the problem have been vague and incomplete. And proposed theories of biological individuality are not detailed enough to solve the problem even if they are correct. The root of these troubles is that their authors have not recognized the metaphysical claims presupposed in their statement of the problem. Making these claims explicit will (...) enable us to see better what the problem is and what form a solution to it would need to have. (shrink)

Kant and Leibniz are interested in explaining how a number of individuals can come together and form a single unified composite substance. Leibniz does not have a convincing account of how this is possible. In his pre-critical writings and in his later metaphysics lectures, Kant is committed to the claim that the idea of a world is the idea of a real whole, and hence is the idea of a composite substance. This metaphysical idea is taken over into his ethical (...) writings and becomes the idea of a realm of ends. I explain why a realm of ends, should be thought of as both a unum per se and as a real whole. A realm of ends is a whole of individuals unified by laws they have given themselves, that is, it is a community of autonomous individuals. Only such a community can be thought of as a composite individual. Such a whole will be real rather than ideal because the source of the unity of the whole is intrinsic to the whole, for what gives unity to the realm are laws and the sources of the laws are the individual members of the whole. It will be a unum per se because both the laws and the individuals constituting the realm are incomplete without one another. If this reading is correct, this requires a fundamental reevaluation of Kant’s notion of autonomy. To be autonomous is not, primarily, to be understood in terms of ruling oneself, but instead must be thought of primarily in terms of being a generative source of laws for an ideal community.

As there is currently a neo-Aristotelian revival currently taking place within contemporary metaphysics and dispositions, or causal powers are now being routinely utilised in theories of causality and modality, more attention is beginning to be paid to a central Aristotelian concern: the metaphysics of substantial unity, and the doctrine of hylomorphism. In this paper, I distinguish two strands of hylomorphism present in the contemporary literature and argue that not only does each engender unique conceptual difficulties, but neither adequately captures the (...) metaphysics of Aristotelian hylomorphism. Thus both strands of contemporary hylomorphism, I argue, fundamentally misunderstand what substantial unity amounts to in the hylomorphic framework – namely, the metaphysical inseparability of matter and form.

Amidst the broad divergence in opinion of philosophers and scientists at understanding reality that has lent character to the historical epochs of the Philosophical enterprise, the crucial realization has always been, of the necessity of Epistemology in our entire program of making inquiry into ‘What Is’. This realization seems born out of the erstwhile problem of knowing. Epistemology, which investigates the nature, sources, limitations and validating of knowledge, offers a striking challenge here. Since we have no direct access to our (...) world around us, outside of the subjective experience offered us by our senses, we are handicapped at making comparisons of our beliefs with a concrete world, out there, or with elements of the world. Our statements about the world seem to stand alone, buffeted against the intimidating tide of possible contradicting circumstances. Our putative claims to knowledge, therefore, face the exigency of justification. Ayer, expressing the urgency of resolving this persisting lacuna, provides an alternative criterion of knowing, as ‘having the right to be sure’. Thus, it is this deep-seated concern that has evolved, over time, to become the primary thrust of the project of Epistemology, raising the controversy over which, of Epistemology or Metaphysics, is to be accorded the prime status of first philosophy. However, Aquinas is wise to build his epistemological premise on a firm metaphysical support, clarifying the needed development from being to knowledge. For, being has to first exist to constitute the object of perception, belief, and knowledge. Accordingly, our exposition of Aquinas’ epistemology will first take a cursory look at the theoretical and historical background to Aquinas’ Philosophy, before offering a general characterization of his theory of knowledge. Then, the paper will discuss his concept of sense perception as a basis for all knowing, followed closely by an analysis of cognition and Scientia. (shrink)

Some attention has also been devoted to a particular kind of judgment or a particular form of the intellect’s second operation, sometimes named separatio by Thomas. Important editions of questions 5 and 6 of Thomas’s commentary on the De Trinitate of Boethius in 1948 and 1955 and the groundbreaking study by L. B. Geiger in 1947, all have set the stage for further emphasis on this distinctive type of intellectual operation when it comes to one’s discovery of being, or better, (...) of that notion of being that can serve as subject of a science of being as being rather than a science of being as material or as quantified. While this new development has remained largely unnoticed in certain regions of Thomistic scholarship for a number of years, it has been pursued in depth by other writers. At the same time, investigation of the same nicely dovetails with the renewed emphasis on existence and on judgment as the process required to discover being as existing to which we have referred above. For as will be seen below, at least one passage in Thomas’s commentary reinforces the contention that one must pass beyond simple apprehension to the mind’s second operation or to judgment if one is to grasp being explicitly as existing. This particular point, however, is not our primary concern here. (shrink)

Thomas Aquinas wrote a text later known as Quaestio de attributis and ordered it inserted in a precise location of his Commentary on the Sentences of Peter Lombard more than a decade after composing this work. Aquinas assigned exceptional importance to this text, in which he confronts the debate on the issue of the divine attributes that swept the most important centres of learning in 13th Century Europe and examines the answers given to the problem by the representatives of the (...) four mainstream schools of his time: the Greek mystic Dionysius Areopagita, the Latin Saint Anselm of Canterbury, the Jewish rabbi Moses Maimonides and the Muslim philosopher Ibn Sina. This in-depth study of Thomas Aquinas’ Quaestio de attributis (In I Sent., d. 2, q. 1, a. 3) binds together the findings of previous research on the unique history of this text by reconstructing the historical circumstances surrounding its composition, shows that the Quaestio contains Aquinas’ final answer to the dispute on the divine attributes, and thoroughly examines his interpretation of Maimonides’ position on the issue of the knowledge of God by analysing this and other texts related to it chronologically and doctrinally. The examination of the Quaestio reveals the background of Thomas Aquinas’ renewed interest in Maimonides’ position on the issue and brings to light elements of Aquinas’ interpretation that are absent from his earlier references to Maimonides. Moreover, the chronological and doctrinal connection of the Quaestio de attributis to other Thomistic works with explicit references to Maimonides enables a reconstruction of his comprehensive approach to Maimonides’ teaching on the possibility and extent of the knowledge of God in the Guide of the Perplexed and highlights the place of Maimonides’ philosophical teachings in Thomas’ own thought in issues like "Being" as the proper name of God, the multiplicity of the divine names, the beatific vision in the afterlife, the causes that prevent the instruction of the multitude in divine matters and the role of faith and prophecy in the acquisition of the true knowledge of God in this life. The last chapter examines the reasons behind Aquinas’ silencing of Maimonides’ name when introducing his Five Ways for the knowledge of the existence of God, in spite of the evident relation between these and Maimonides’ Four Speculations. The study is completed with an extensive appendix that includes the text of the Quaestio de attributis with an English translation and the critical edition of several chapters of the 13th Century Latin translation of the Guide of the Perplexed known as Dux neutrorum.

The belief that Aristotle opposes potency (dunamis) to actuality (energeia or entelecheia) has gone untested. This essay defines and distinguishes forms of the Opposition Hypothesis—the Actualization, Privation, and Modal—examining the texts and arguments adduced to support them. Using Aristotle’s own account of opposition, the texts appear instead to show that potency and actuality are compatible, while arguments for their opposition produce intractable problems. Notably, Aristotle’s refutation of the Megarian Identity Hypothesis applies with equal or greater force to the Opposition Hypothesis. (...) For Aristotle, then, potency and actuality are compatible.

Discussions of immortality in the Middles Ages tend to focus on the nature of the rational soul and its prospects for surviving the death of the body. The question of how medieval figures expected to experience everlasting life—what I will be calling the phenomenology of immortality—receives far less attention. In this paper, I explore the range of these expectations during a relatively narrow but intensely rich temporal and geographical slice of the Middle Ages (the thirteenth and fourteenth centuries in (...) the ‘Latin Christian West’). In section 1, I sketch the two central accounts of the rational soul and human nature (inspired by the Platonist and Aristotelian traditions) that set the metaphysical parameters for medieval discussions of our experience of the afterlife. In section 2, I address accounts that involve transcending the soul’s experiences of itself as an individual. In section 3, I turn to views that emphasize the embodied aspect of human existence and depict our unending union with God in affective and physical terms. In section 4, I argue that the views discussed in 2 and 3 form endpoints of an ‘experiential continuum of immortality’ that provides important context for scholastic accounts of immortality as well as expanding the traditional narrative of medieval philosophy.

In Aquinas's account of the beatific vision, human beings are joined to God in a never-ending act of contemplation of the divine essence: a state which utterly fulfills the human drive for knowledge and satisfies every desire of the human heart. In this paper, I argue that this state represents less a fulfillment of human nature, however, than a transcendence of that nature. Furthermore, what’s transcended is not incidental on a metaphysical, epistemological, or moral level.

The aim of this paper is to apply the metaphysics of John Duns Scotus in constructing a new conception of matter which does not stand in opposition to the mental realm, but is rather composed of both physical and mental elements. The paper is divided into four parts. Section one addresses Scotus’ claim that matter is intelligible and actual in itself. Section two aims to show that matter can be seen as a deprived thinking being. Section three analyzes Scotus’ conception (...) of place. The final section brings together the conclusions of the three preceding parts to confront the Cartesian psycho-physical problem anew and to suggest a viable solution. (shrink)

Arguments concerning the nature of natural evil vary in their conclusions depending on the particular approach with which they commence inquiry; one of the most contested conclusions regards evil as privation, sourcing its justification primarily from Aquinas’ metaphysical conception of good as being and evil as non-being. It should be of no surprise, then, that the dismissal of natural evil’s privative nature comes about when the understanding of natural evil favours a phenomenological approach rather than a metaphysical one. Proponents of (...) said dismissal generally centre their claims around the notion of pain and suffering as substantially contentful – as in, non-privative – experiences of evil. On the other hand, theorists espousing the privation account generally argue that characterisations of pain and suffering as necessarily evil do not consider the context of orientation towards individual wellbeing within which pain/suffering experiences naturally function. Furthermore, some of the arguments for the privation account’s dismissal seem to disregard completely the Thomistic sense of the form and hierarchy of the good, which ends up straw-manning the privation account to a point where it can no longer reconcile the awfulness of experienced pain and suffering with these experiences not being necessarily evil. The importance of understanding this Thomistic sense is further emphasised in its capacity to explain why a divine and fully good Creator would involve the world with such evil. Thus, this paper first considers the account of evil given in question one of Aquinas’ De malo, along with contemporary arguments for the nature and purpose of evil as privation; second, these are then used as resources to help make sense of, one, the general nature of pain and suffering, and two, some of their specific expressions as found in disease and depression, and throughout evolutionary history.

In this paper I argue that Aquinas’ account of analogy provides resources for resolving the prima facie conflict between his claims that (1) the divine relations constituting the persons are “one and the same” with the divine essence; (2) the divine persons are really distinct, (3) the divine essence is absolutely simple. Specifically, I argue that Aquinas adopts an analogical understanding of the concepts of being and unity, and that these concepts are implicit in his formulation of claims about substance (...) and relation in the Trinity. I then show how Aquinas appeals to key structural features of analogical concepts, notably, the simpliciter/secundum quid characterization, to resolve apparent conflicts between the unity of substance and distinction of relations in the Trinity.

The 16th and 17th centuries witnessed a philosophical shift that would help pave the way for modern science, a shift from metaphysical theories of material objects to other views embracing only the empirically-accessible parts of material things. One much-debated topic in the course of this shift was regarding prime matter. The late scholastic Jacobus Zabarella (1533-1589) arrived upon his views about prime matter via his version of the regressus method, a program for a sort of scientific reasoning. In (...) his De rebus naturalibus, Zabarella defends the position that prime matter is extended. However, it is less clear how he accounts for its extension. There is an important text where he apparently suggests that prime matter is extended in and of itself. However, there are two other texts apparently stating that matter is extended in virtue of a distinct accident in the category of quantity. I argue that a decisive reading based solely upon any particular texts is not available. Nevertheless, examining Zabarella’s writing on the topic as a whole, the trajectory of his overall argument is remarkably sympathetic to Averroes, who famously took the accidentally quantified position. Thus, from this systematic feature, the accidentally quantified reading is more reasonable. (shrink)

Predication is a lingual relation. We have this relation when a term is said (λέγεται) of another term. This simple definition, however, is not Aristotle’s own definition. In fact, he does not define predication but attaches his almost in a new field used word κατηγορεῖσθαι to λέγεται. In a predication, something is said of another thing, or, more simply, we have ‘something of something’ (ἓν καθ᾿ ἑνὸς). (PsA. , A, 22, 83b17-18) Therefore, a relation in which two terms are posited (...) to each other in a way that one is said (predicated) of the other is a predication. The term of which the other term is said is called a subject (ὑποκειμένον) and the other, which is said about the subject, is called the predicate. Thus, in a predication the predicate is predicated of the subject; given that being predicated is almost as the same as being said. The relation between being said and being predicated is so close that ‘if something is said of a subject both its name and its definition are necessarily predicated of the subject.’ (Cat., 5, 2a19-26) This, however, is true only about the second genera and not the accidents. a) Nature of relation in predication What is Aristotle’s theory about the nature of the relation in a predication? How does he fundamentally understand this relation? Phil Corkum distinguishes between predication logic and traditional term logic and argues that the relation between subject and predicate in Aristotle is of the latter kind. While in predicate logic, subjects and predicates have distinct roles, they have the same role in traditional term logic. In predication logic, subjects refer, but predicates characterize. Thereupon, a sentence expresses a truth if the object to which the subject refers is correctly characterized by the predicate. In traditional term logic, both subjects and predicates refer and a sentences expresses a truth if both name one and the same thing. He concludes that Aristotle ‘problematically conflates prediction and identity claims’ because while he thinks both subjects and predicates refer, he would deny that a sentence is true just in case the subject and the predicate name one and the same thing. Based on this, Corkum believes that Aristotle’s core semantic is not identity but the weaker relation of constitution, which is a mereological interpretation: ‘All men are mortal’ is true just in case the mereological sum of humans is part of the mereological sum of mortals. b) Aristotle’s theory of predication: one or two theories? Frank Lewis finds an inconsistent gap between the theory of predication in the Categories and that in the later books of the Metaphysics VII, 6. So too Joan Kung, Terry Irwin, Daniel Graham. c) Distinction of ‘being said of’ and ‘being in’ Owen enumerates the texts in which Aristotle’s distinction between ‘being said of’ and ‘being in’ is asserted: OI. 11b38-12a17; To., 127b1-4; Cat. 1a20-b9; 2a11-14; 2a27-b6; 2b15-17; 3a7-32; 9b22-24 d) Predication in Aristotle and the standard ‘S is P’ Marie De Rijk Lambertus thinks that the ‘S is P’ pattern is misleading when it comes to express predication in Aristotle. In his view, ‘The Aristotelian procedure should be described in terms of appositively assigning an attribute (κατηγορούμενον) to a substrate (ὑποκείμενον), rather than ascribing a predicate to a subject by means of a copula…. The comment should be considered an attribute which is said to fall to a substrate, without understanding this procedure in terms of sentence predication.’ e) Aristotle’s predication: bipartite or tripartite? It is a difficulty to make Aristotle’s theories of name-verb predication and tripartite predication consistent. The reason is that tripartite is not consistant with his name-verb structure based on which he says that the predicate term is the ‘verb.’ (20a31; 20b1-2; 16a13-5) The problem is that in a tripartite form like ‘Socrates is white’ we cannot take ‘is white’ as the verb because, based on Aristotle himself, no part of a verb can be significant itself. (16b6-7) However, his assertions about the equivalences between the two structures (OI. 12, 21b9-10; PrA. 51b13-16; Met., 1017b22-30) must mean that they are not inconsistent in his own view. Thus, as Allen Bāck points, ‘Aristotle seems to think that he has a single, consistent theory.’ The sense of saying or speaking as the root sense of rhema makes the relation between predication (saying something of something) and verb more interesting. The use of rhema in the sense of a long expression approves this. In Plato’s work (399ac) where Socrates claims that the name anthropos derives from anthron ha opopen (‘he who examines what he has seen’) we have an onoma from, or in place of, a rhema. 1) Subject The subject (ὑποκειμένον) is that of which another term is said or predicated. Aristotle’s own definition is of a much more philosophical value: ‘By subject I mean that which is expressed by an affirmative term (λέγω δὲ ὑποκείμενον τὸ κάταφάσει δηλούμενον).’ (Met., K, 1067b18) Throughout Aristotle’s work, three kinds of subjects can be found: possible, prime and absolute subject. a) Possible subject Those things that can take the position of a subject in a predication we call possible subjects, no matter they can or cannot take the position of predicate in any predication. All terms except the ultimate predicates are possible subjects because they can take the position of subject. b) Prime subject Those that in any predication can only take the position of a subject and not the position of a predicate are prime subjects. (Cat., 5, 3a36-b2; Met., Z, 1028b36-1029a1) This is the truest sense of subject and belongs only to substances. (Met., Z, 1029a1-2) In fact, ‘that which is not predicated of a subject, but of which all else is predicated’ is a substance. (Met., Z, 1029a7-9) In Categories, besides primary substances (Cat., 2, 1b3-6), individual qualities are also said not to be able to be said of anything else. (Cat., 2, 1a23-29) Aristotle’s examples are a certain ‘knowledge-of-grammar’ (τὶς γράμματικὴ) and ‘an individual white’ (τὸ τὶ λευκὸν). Thus, although substances are indeed in the truest sense individuals and, thereby, in the truest sense primary subjects, other individuals can take the position of subject as well. c) Absolute subject While substances are prime subjects of all other things, there is still something of which substances can be predicated and this predication is not an accidental predication: matter. (Met., Z, 1029a21-24) This predication is, indeed, the predication of a ‘form or this’ on matter and material substance. (Met., Θ, 1049a34-36) The only thing that is absolutely a subject, therefore, and can be a predicate is prime matter (πρώτη ὓλη). (Met., Θ, 1049a24-27) d) Subject and substance The most important thing in being a substance is being a subject: ‘It is because the primary substances are subjects for all the other things and all the other things are predicated of them or are in them, that they are called substances most of all.’ (Cat., 5, 2b15-17) And what is nearer to this position is more a substance as a species is more a substance than a genus.’ (Cat., 5, 2b7-8) e) Primary versus accidental subject A subject is a primary subject in a predication when the predicate is predicated of it as itself. In such a case, the subject is the subject of the predicate qua itself and not qua something else. A subject, on the one hand, is an accidental subject when it is not the primary subject of the predicate that is predicated on it. It means that a subject is an accidental subject when the predicate is predicated of it not qua itself but qua something else. An accidental subject is, therefore, anything other than a substance. 2) Predicate as universal It is evident from our discussion of kinds of subjects that except matter, primary substances (if we ignore both accidental predication and cases of absolute subjects) and other individuals, everything else can take the position of a predicate. Since primary substances are individuals, it results that everything except matter and individuals are capable to take the position of predicate. The immediate consequence of this is that the predicate must be a universal. When individuals cannot take the position of predicate, this position cannot be taken by any particular. Therefore, only universals can be predicated of others. Moreover, albeit universals can be a simple subject (for another universal), they are not prime subjects. The closeness of universal and predicate is to the extent that Aristotle differentiates universal from subject. (Met., Θ, 1049a27-30) 3) Categories or classes of predicates Aristotle distinguishes ten highest classes into one of which each predicate must necessarily fall: substance (or what a thing is), quality, quantity, relation, place, time, position, state, activity and passivity. (Cat., 4, 1b25-27; To., I, 9, 103b20- ; PsA., A, 22, 83b13-23) The substance counted among predicates must refer to secondary and not primary substances not only because Aristotle insists that primary substances cannot be predicated but also from his own examples of the category of substance: man and animal. (To., I, 9, 103b25) However, if a predicate be asserted of itself or its genus be asserted of it, the predicate signifies substance or what is; but if ‘one kind of predicate is asserted of another kind,’ it signifies one of the other nines. (To., I, 9, 103b30) These categories are so comprehensive that no predicate can remain outside them so that even non-being has as many senses as categories. (Met., M, 1089a26-30) a) That whether Aristotle’s categories are merely linguistic or fundamentally ontological is a so much controversial dispute. Some like G. E. R. Lloyd believe that ‘categories are primarily intended as a classification of reality … rather than of the signifying terms themselves.’ b) Although Aristotle’s categories have been historically regarded as a classification of predications, there are some recent commentators like Jonathan Barnes that think it is classifying predicates and not predications. 4) Kinds of predicates In his introduction of Categories, as J. W. Thorp truly points out , Aristotle distinguishes between the category of substance and the other categories using μὲν ... δὲ construction. This construction illustrates that beside tenfold classification of categories, there is an even more crucial differentiation between two kinds of predicates: substance or what is on the one hand and the other nine ones on the other hand: the distinction between what is predicated of the subject as what it is and what is predicated of it as an accident. Therefore, we have three kinds of classification - a twofold, a fourfold and a tenfold-complicatedly classifying the same thing, viz. the predicate. Predicates can be divided also to four kinds: property, definition, genus and accident. (To., I, 4, 101b11-20) A property is that predicate that is convertible with its subject and does not signify its essence. A definition is that predicate that is convertible with its subject and signifies its essence. It is a genus if it is not predicated convertibly and is contained in the definition of its subject. And it is an accident if it is neither convertible nor contained in the definition of its subject. (To., I, 8, ^103b3) All of these four kinds are among categories. (To., I, 9, 103b20) It seems that there might be some kind of relation between the twofold and the fourfold distinction: whereas genus and definition are predicated as what it is, accidents are not so predicated. There seems to be some rules that determine to each of these four kinds each predicate belongs. At To., IV, 123b30ff. Aristotle asserts: ‘If B has a contrary and A does not, then B does not belong to A as its genus.’ There is a dispute around per se accidents (τὰ καθ’ αὑτὰ συμβεβηκότα) (Topics., 102a18) whether they must be regarded as either of the four kinds or as a fifth kind. Barnes (1970) argued that they ‘do not fit at all neatly into the fourfold classification.’ He argues that based on the definition of accidents at A, 5, 102b4-5, they must be accidents but based on another definition, A, 5, 102b6-7, they cannot be accidents. He also defends the view that they are not properties. Barnes concludes: ‘This shows that the two definitions are not equivalent, and hence that the ‘predicables’ are not well-defined.’ Demetris J. Hadgopoulos defends the view that the two definitions of accidents are equivalent and per se accidents are properties. 5) Five types of predications We have five kinds of predications based on our division of subjects and our discussion of predicates: simple, primary (itself divided to substantial and accident), accidental (itself divided to primary and secondary), aoincidental and absolute predication. a) Simple predication. This is a predication in which a universal is predicated of either a particular or a universal subject. This sense of predication includes all other senses except the first kind of accidental predication. b) Primary predication. This is a predication in which a universal is predicated of a primary subject, namely a substance. A primary predication is of two kinds: i) Substantial predication. A primary predication in which the predicate is part of, or is included in, the definition of the subject. The universal that is the predicate here is the definition or the genus or the species or the diferentia of the subject. It is this predication that Aristotle calls a unity: ‘A statement may be called a unity … because it exhibits a single predicate as inhering not accidentally in a single subject.’ (PsA., B, 10, 93b35-37) It is only substantial predicates that can be predicated of each other: ‘Predicates which are not substantial are not predicated of one another.’ (PsA., A, 22, 83b18-19) Aristotle defines a substantial predication also in another way. A predication in which a higher genus is predicated on a lower genus, species, a substance or an individual, (or a species is predicated on an individual) is a substantial predication. Therefore, a substantial predication is a predication in a series that has individuals on one of its ends and a general category on its other end. In fact, only substantial predicates can be predicated of one another. (PsA., A, 22, 83b17-19) This series cannot be an infinite series because otherwise not only substances would not be definable but also a genus would be equal to one of its own species. (PsA., A, 22, 83b7-10) -/- ii) Accident predication. A primary predication in which the predicate is not part of, or is not included in, the definition of its subject. The universal that is the predicate here is the property or the accident of the subject. c) Accidental predication. This is a predication in which the subject is not a primary subject and its predicate is a substance. This predication is of two kinds: i) Primary accidental predication. This is a predication in which an accident is predicated of substance. Such a predication can go ad infinitum, which is inferable from Aristotle’s assertion that the secondary accidental predication cannot go ad infinitum. ii) Secondary accidental predication. It is a predication in which an accident is predicated of another accident. Such a predication, Aristotle asserts, cannot go ad infinitum because even more than two accidents cannot be combined. Now what is the meaning of Aristotle’s assertion that we cannot continue this ad infinitum? Does it mean that we cannot continue the predication ‘The musician is white’ and say ‘The white is Athenian?’ But why not? Or maybe he means that by adding any predication, we are still in a condition of predicating two accidents of a substance on each other. -/- As primary subjects, substances can also take the position of predicate though not essentially but accidentally. In propositions like ‘the white is a log’ or ‘That big thing is a log’ we observe substance taking the position of predicate but this is only accidentally: ‘When I affirm ‘the white is a log,’ I mean that something which happens to be white is a log- not that white is the subject in which log inheres (οὐχ ὡς τὸ ὑποκείμενον τῷ ξύλῳ τὸ λευκόν ἐστι), for it was not qua white or qua a species of white that the white (thing) came to be a log (οὔτε λευκὸν ὄν οὔθ᾿ ὃπερ λευκόν τι ἐγἐνετο ξύλον), and the white (thing) is consequently not a log except incidentally.’ (PsA., 22, 83a3-9) Aristotle compares this accidental use of substance in the position of predicate with the substantial use of it in the place of a subject: ‘On the other hand, when I affirm ‘the log is white,’ I do not mean that something else, which happens to be a log, is white (οὐχ ὃτι ἓτερόν τί ἐστι λευκόν, ἐκείνῳ δὲ συμβέβηκε ξύλῳ εἶναι), (as I should if I said ‘the musician is white,’ which would mean ‘The man who happens also to be a musician is white’); on the contrary, log is here the subject- the subject which actually came to be white, and did so qua wood or qua a species of wood and qua nothing else.’ (PsA., 22, 83a8-14) Aristotle asks us not to call propositions like ‘The white is a log’ a predication at all or at least call them accidental predication instead of simple (ἁπλως) predication. (PsA., A, 22, 83a14-17) An accidental predication, in which we have a substance in the place of predicate, is different from an essential predication in that while the subject of an accidental predication is said to be the predicate not by itself but as something different with which it coincides, the subject of an essential predicate is said to be the predicate by itself and not because it is something else: ‘Since there are attributes which are predicated of a subject essentially and not accidentally- not, that is, in the sense in which we say ‘That white (thing) is a man,’ which is not the same mode of predication as when we say ‘The man is white’: the man is white not because he is something else but because he is man, but the white is man because ‘being white’ coincides with ‘humanity’ within one subject. Therefore, there are terms such as are essentially subjects of predicates. (PsA., A, 19, 81a24-29) This capability of ‘non-essentially and only accidentally’ being a subject does belong, in fact, to all sensible things. (PsA., A, 27a32-36) d) Coincidental predication. this is a predication in which none of the subject and predicate are a substance or an individual. In this predication, one of the accidents of a substance or individual is predicated of one of the other accidentals of the same substance or individual. For example, when it is said that ‘The white is musical,’ there is an individual, say Socrates, for which both of white and musical are accidents. e) Absolute predication. This is a predication in which a form or a substance is predicated of a matter or a material substance. Some commentators like Loux and Lewis regarded this predication as close to accident predication, both based on inherence. As R.M. Dancy points out, these predications make Aristotle’s theory of predication immanentist: not only accident predications are explained by the immanence of accidents in substances, some of the substantial predications, which were not explained in Categories, are also explained by the immanence of form in matter. It is interesting that in this kind of predication, it is the predicate and not the subject, which is in the strictest sense substance. As the central books of Metaphysics claim, the form is the substance. Thus, in this predication, substance gets away from the sense of ὑποκείμενον. Corkum mentiones 68a19 as the only instance where Aristotle explicitly claims that a term may be predicated of itself, a passage that is, in Corkum’s view, problematic. 6) Demonstrable predicates Those predicates are demonstrable that are so related to their subjects that there are other predicates prior to them predicable of their subjects (ἔτι δ᾿ ἄλλος, εἰ ὧν πρότερα ἄττα κατηγορεῖται). (PsA., A, 22, 83b32-34) 7) Series of predications Since it is possible for a predicate to be itself the subject of another predication, we can have a series of predications in which the predicate of a predication is the subject of the next predication. This series has the following features: a) It has a limit (in number) (PsA., A, 22, 83b14-16) on the side of subjects: there are subjects that cannot themselves be predicated (PsA., A, 27, 43a39-41), which are, as we noted, prime subjects: particulars, i.e. prime substances and other individuals. (PsA., A, 19-22) Aristotle calls them ultimate (ὓστατον). (PsA., 21, 82a36-b1) b) It has a limit (in number of kinds) (PsA., A, 22, 83b14-16) also on the side of predicates: there must be predicates that cannot be subjects. (PsA., A, 19-22; PsA., A, 27, 43a36-39) Aristotle calls them primary (πρῶτον). (PsA., A, 21, 82b1-4) These are the highest categories or the highest genera of categories. (PsA., A, 22, 83b14-16) c) The series has an escalating shape from mere subjects at its downside to mere predicates at its upside. It is Aristotle himself whos uses the words up and down in this sense. (e.g. PsA., A, 22, 83b2-3) d) The predications that lie between lowest and highest ones must be finite in number. (PsA., A, 19-22 especially: 20, 82a21-35) These have subjects and predicates, each capable of both of the roles of being subject and being predicated. A result of this fitness is that neither demonstration can go to infinity nor everything is demonstrable, the two points Aristotle always insist on. e) The upward side includes the more universal ones and the downward the more particular ones. (PsA., 20, 82a21-23) f) It follows from the above features that ‘neither the ascending nor the descending series of predications … are infinite.’ (PsA., A, 22, 83b24-25) g) Reciprocation and convertibility. Except in case of terms (i.e. subjects and predicates) that are at each of the ends of series of predications, namely ultimates and primaries, it is possible to reciprocate (ἀντιστρέφειν) terms and convert the predication. (PsA., A, 19, 82a15-20) h) Antipredication. Antipredication means that in a predication (S is P), the subject becomes the predicate of its predicate (P is S) in the same category its predicate was predicated on it. For example, if P is in the category of quality, antipredication means that S be predicated of P in the category of quality. In other words, P is a quality of S and S is a quality of P. Aristotle rejects this. (PsA., A, 22, 83a36-b3) i) Self-predication versus other-predication. Aristotle distinguishes between a predication in which a term is said of itself and a predication in which a term is said of another. (Phy., Δ, 2, 209a31-33) j) Predicablity (Cat., 5, 3a36-b2): 1) Primary substances and individuals are not predicable. 2) Secondary substances are of two kinds: genus and species i) Genus is predicable able both of the species and of the individuals. ii) Species is predicable of the individual. 3) Differentiae are predicable both of the species and of the individuals. 8) Predication as classification a) Richard Patterson believes that Aristotle’s so repeated construction using hoper (estin A hoper B) in Topics (120a23 sq., 122b19, 26sq., 123a, 124a18, 125a29, 126a21, 128a35. Also in Posterior Analytics (83a24-30) (Brunschwig’s list. ‘expresses the fact that A is a kind of B (esti A B tis), that A is a species of the genus B.’ 9) Universal predication Aristotle defines universal predication (κατὰ παντὸς κατηγορεῖσθαι) as such: ‘wherever no instance of the subject (τῶν τοῦ ὑποκειμέμνου) can be found of which the other term cannot be asserted.’ (PrA., A, 24b27-29) In this predication, the subject is included in another as in a whole (ἐν ὃλῳ εἶναι) and the predicate is predicated of all of the subject (κατὰ παντὸς κατηγορεῖσθαι). (PrA., A, 24b26-27) Attach another discussion we had about ἐν ὃλῳ here. 10) Quantity of predication A predication, truly stated, has a quantity, which is the number of objects under the name of the subject of which the predicate is predicated. The quantity of subject can be stated in four ways: a. Indefinite: when the predicate belongs or does not belong to the subject without any mark to show to haw many of the particulars under the name of the subject it does or does not belong. E.g. ‘Man is white’; ‘Man is not white.’ (PrA., A, 24a20; OI., I, 7, 17b8-12) b. Universal quantity: When the predicate belongs to all or none of the subject. E.g. ‘Every man is animal’; ‘No man is animal.’ (PrA., A, 24a18-19; OI., I, 7, 17b5-6) The contrary of a predication of a universal quality is a predication of a universal quality. E.g. the contrary of ‘Every man is white’ is ‘No man is white.’ (OI., I, 7, 17b20-23) c. Particular quantity: When the predicate belongs (or does not belong) to some of the subject. E.g. ‘Some men are white’; ‘Some men are not white.’ (PrA., A, 24a19-20) d. Single quantity: when the subject is a proper name of only one object. E.g. ‘Socrates is white’; ‘Socrates is not white.’ The contrary of this predication is of a single quantity: ‘Socrates is not white.’ (OI., I, 7, 17b38-18a4) 11) Convertibility of predication. Some predications are convertible, that is, it is possible to change the place of subject and predicate in a true proposition so that the converted proposition remains true. This is supposed to mean that given the truth of a predication, the truth of the converted predication is inferable. The convert form of a predication depends on its quantity. a. Indefinite quantity: This predication has no strictly true convert because its quantity is not stated. b. Universal quantity: It can be converted in two ways: i) A negative universal can be converted to a negative universal in which the terms are changed. E.g. ‘No pleasure is good’ can be converted to ‘No good is pleasure.’ (PrA., A, 2, 25a5-8 and a14-19) ii) An affirmative universal can be converted to an affirmative particular in which the terms are changed. E.g. ‘Every pleasure is good’ can be converted to ‘Some good is pleasure.’ (PrA., A, 2, 25a7-9) c. Particular quantity: If it is negative, it cannot be converted but if it is affirmative, it can be converted to an affirmative predication with particular quantity. E.g. ‘Some pleasure is good’ can be converted to ‘Some good is pleasure.’ (PrA., A, 2, 25a10-13 and a20-24) d. Single quantity: It cannot be converted. 12) Characteristics of relations between subject and predicate 1. A predicate is of a wider range than its subject. It is based on this fact that Aristotle: a) Prevents individuals to be predicate because there is nothing of which an individual be of a wider range. In other words, it is due to the fact that since an individual is only ‘one particular’ thing and, thus, cannot be of a wider extent than anything that Aristotle prevents them of being a predicate. Matthews, however, thinks we cannot use Socrates, a substance and an individual, in the place of predicate and say it of Socrates because ‘Socrates does not classify Socrates: it names him.’ b) Prevents differentia, species and things under species to be predicated of genus. (To., Z, 6, 144a27-) c) Prevents the species and the things under it to be predicated of the differentia. (To., Z, 6, 144b1-4) d) Also about the effect because it is wider than its subject. (PsA., B, 17, 99a) e) Each attribute is wider than every individual it is predicated on, though several attributes, collectively considered, might not be wider but exactly the substance of a thing. (PsA., B, 13, 96a32-b1) 2. The predicate of a predicate of a subject will be predicated of the subject too: ‘whenever one thing is predicated of another as of a subject, all things said of what is predicated will be said of the subject too.’ (Cat., 3, 1b10-15) In fact, it is due to its predication of the subject that it is predicated of its predicate. (Cat., 5, 2a36-b1) Moreover, what is not predicated of the predicate of a subject cannot be predicated of it as well. (PrA., A, 27, 43b22-27) Thus, what, for example, is not predicated of animal, cannot be predicated of man. 3. The predicate of a subject can be predicated of its predicates as well. (Cat., 5, 3a1-6) For example, you call the individual man grammatical and, thence, you call both a man and an animal grammatical. Nonetheless, the predicate of a subject belongs to it more properly than to its higher predicates. (PrA., A, 27, 43a27-32) 4. It is only the subject that can be distributed and not the predicate. (PrA., A, 27, 43b16-22; OI, I, 7, 17b12-16) Therefore, we can say e.g. ‘Every man is animal’ but we cannot say ‘Every man is every animal.’ 5. It is the reason of the relation between subjects and predicates, that is the reason of predication, which is the subject of inquiry. (Met., Z, 1041a20-24) In other words, since it is a meaningless inquiry to ask why a thing is itself (Met., Z, 1041a14-15), the only remaining meaningful inquiry is to ask why something is something else, i.e. to ask about the reason of predication. 6. A subject cannot categorize its predicate in the same category in which it is categorized by it. If e.g. A is a quality of B, B cannot be a quality of A. Therefore, there is no reciprocation in the same category. (PsA., A, 22, 83a36-39) 13) Characteristics of series of predications 1. A series of secondary accidental predication cannot go ad infinitum for not even more than two terms can be comnbined. For an accident is not an accident of an accident, unless it be because both are accidents of the same subject. (Met., Γ, 1007b1-4) 2. Infinite series cannot be traversed in thought. (PsA., A, 22, 83b6-7) 3. The predications of genera on each other must be ended and cannot go to infinity because otherwise not only substances would not be definable but also a genus would be equal to one of its own species. (PsA., A, 22, 83b7-10) Therefore, a series of predication of genera on each other must be limited on both sides. There must be an upward limit in general categories as well as a downward limit in individual because they cannot be predicated of others. Whatever lies between these limits can both be predicated of others and others be predicated of them. (PrA., A, 27, 43a36-43) 4. The order of predicates matters: it makes a difference whether the series be ABC or BAC. (PsA., B, 13, 96b25-32) . (shrink)

The nature of vagueness is investigated via a preliminary definition and a discussion of the classical sorites paradox ; this is carried further by asking for the origins of vagueness and a critique of several attempts to remove it from language. It is shown that such attempts are ill motivated and doomed for failure since vagueness is not just a matter of ignorance but firmly grounded in epistemic and metaphysical facts. Finally, the philosophical interest of real (...) class='Hi'>vagueness is illustrated by the concept of “natural kind”, which is essential to realism/anti-realism debates. (shrink)

To the extent that dualism is even taken to be a serious option in contemporary discussions of personal identity and the philosophy of mind, it is almost exclusively either Cartesian dualism or property dualism that is considered. The more traditional dualism defended by Aristotelians and Thomists, what I call hylemorphic dualism, has only received scattered attention. In this essay I set out the main lines of the hylemorphic dualist position, with particular reference to personal identity. First I argue that overemphasis (...) of the problem of consciousness has had an unhealthy effect on recent debate, claiming instead that we should emphasize the concept of form. Then I bring in the concept of identity by means of the notion of substantial form. I continue by analyzing the relation between form and matter, defending the traditional theses of prime matter and of the unicity of substantial form. I then argue for the immateriality of the substantial form of the human person, viz. the soul, from an account of the human intellect. From this follows the soul's essential independence of matter. Finally, although the soul is the immaterial bearer of personal identity, that identity is still the identity of an essentially embodied being. I explain how these ideas are to be reconciled. Footnotesa I am grateful to Stephen Braude, John Cottingham, John Haldane, David Jehle, Joel Katzav, Eduardo Ortiz, and Fred Sommers for helpful comments and discussion of a draft of this essay. I would also like to thank Ellen Paul, whose suggestions have helped greatly to improve the essay's style and content. (shrink)

Aristotle analyses a large range of objects as composites of matter and form. But how exactly should we understand the relation between the matter and form of a composite? Some commentators have argued that forms themselves are somehow material, that is, forms are impure. Others have denied that claim and argued for the purity of forms. In this paper, I develop a new purist interpretation of Metaphysics Z.10-11, a text central to the debate, which I call 'hierarchical purism'. I argue (...) that hierarchical purism can overcome the difficulties faced by previous versions of purism as well as by impurism. Roughly, on hierarchical purism, each composite can be considered and defined in two different ways: From the perspective of metaphysics, composites are considered only insofar as they have forms and defined purely formally. From the perspective of physics, composites are considered insofar as they have forms and matter and defined with reference to both. Moreover, while the metaphysical definition is a definition in the strict sense of 'definition', the physical definition is a definition in a loose sense. Analogous points hold for intelligible composites and geometry. Finally, neither sort of definitional practice implies that, for Aristotle, forms are impure. (shrink)

Aquinas, Ockham, and Burdan all claim that a person can be numerically identical over time, despite changes in size, shape, and color. How can we reconcile this with the Indiscernibility of Identicals, the principle that numerical identity implies indiscernibility across time? Almost all contemporary metaphysicians regard the Indiscernibility of Identicals as axiomatic. But I will argue that Aquinas, Ockham, and Burdan would reject it, perhaps in favor of a principle restricted to indiscernibility at a time.

In this paper I argue that, in Leibniz’s mature metaphysics, primary matter is not a positive constituent which must be added to the form in order to have a substance. Primary matter is merely a way to express the negation of some further perfection. It does not have a positive ontological status and merely indicates the limitation or imperfection of a substance. To be sure, Leibniz is less than explicit on this point, and in many texts he writes as if (...) primary matter were a positive constituent of a substance. It seems to me, however, that the view most in keeping with the thrust of his mature philosophical system is that captured by a striking remark of 1695: “Materia rerum est nihilum: id est limitatio [The matter of things is nothing: that is, limitation].” This becomes especially apparent in texts showing that Leibniz’s conception of primary matter corresponds to his conception of creaturely limitation. I start by discussing the notion of primary matter in the scholastic tradition. I then show that although Leibniz places the scholastic terminology of primary matter at a crucial juncture of his metaphysics, he thinks of primary matter in a way which significantly deviates from earlier scholastic views. I conclude that despite his adoption of distinctive terminology of Aristotelian scholasticism, instead of holding a broadly Aristotelian concept of primary matter as the ultimate subject of inherence, Leibniz thinks of primary matter according to a Neoplatonic blue-print in which matter is non-being, privation, mere absence of perfection.

I argue that the prime matter that Leibniz posits in every created monad is understood by him to be a mere defect or negation, and not something real and positive. Further, I argue that Leibniz’s talk of prime matter in every created monad is inspired by the thirteenth-century doctrine of spiritual matter, but that such talk is simply one way in which Leibniz frames a point that he frequently makes elsewhere—namely, that each creaturely essence incorporates a limitation that (...) is the ultimate source of an original imperfection that affects the creature from the first moment of its existence.

[Encyclopedia entry] Born in Italy in 1225, and despite a relatively short career that ended around 50 years later in 1274, Thomas Aquinas went on to become one of the most influential medieval thinkers on political and legal questions. Aquinas was educated at both Cologne and Paris, later taking up (after some controversy) a chair as regent master in theology at the University of Paris, where he taught during two separate periods (1256-1259, 1269-1272). In the intermediate period he helped (...) establish a studium for his Order in Rome, beginning work on the Summa Theologiae, the masterwork for which he is still well-known. Subsequent to an experience (traditionally, a vision) Aquinas had on the feast of St. Nicholas in 1273, Aquinas intentionally refrained from further work on that text, so that it remained incomplete at the time of his death a year later in 1274. Apart from his own contributions, the Thomistic school – including followers within and without the Dominican Order to which Aquinas belonged – has had profound and far-reaching influence upon the history of legal thought in the West. Many of the classical developments of Thomistic thought are written as commentaries on the Summa Theologiae (hereafter, ST), including the works of Tomasso de Vio (Cajetan) and those of Domingo Banez, Francisco de Vitoria, Bartholome de las Casas, and the other highly influential members of the School of Salamanca who are noteworthy for developing Aquinas’ political and legal thought in the 16th century. Specifically, the ways in which Aquinas synthesized classical political and legal themes around the law, morality, and the common good provided a touchstone for what has come to be called ‘natural law jurisprudence.’ Natural law thinkers, in short, appeal to objective facts about what is good for human beings, and the social or political nature of the kind of creatures that we are, as a standard against which we measure the legal and social institutions created by human institutions. What is crucial here is that facts about human beings as social animals constitute reasons for individuals and groups to act or be structured in certain ways, such that ‘nature’ is the proper source for jurisprudential and political principles.

Divine simplicity is central to Thomas Aquinas’s philosophy of God. Most important for Aquinas is his view that God’s existence (esse) is identical to God’s essence; for everything other than God, there is a distinction between existence and essence. However, recent developments in analytic philosophy about the nature of existence threaten to undermine what Aquinas thought regarding divine simplicity. In the first chapter of this dissertation, I trace Aquinas’s thinking on divine simplicity through the various texts he wrote regarding the (...) matter. I establish that it is crucial for Aquinas that God is identical to his existence. But, is it even coherent to talk about “a thing’s existence?” In Chapter Two I summarize the arguments of C.J.F. Williams that existence is not a real property that individuals have and that predicating the word “exists” after the name of an individual produces linguistic gibberish. After considering, and rejecting, in Chapter Three attempts by some philosophers to refute Williams’s arguments, I turn, in Chapter Four, to a more detailed account of what Aquinas means by esse, the Latin word often rendered in English as “existence.” The conclusion that I come to is that Aquinas does not mean by esse what contemporary philosophers have usually meant by “existence.” Rather, he understands esse to be the act by which anything can be anything at all, instead of there being nothing whatsoever. In the final chapter, I turn to implications of this for Aquinas’s views of divine simplicity, showing that rather than being incoherent, Aquinas’s thinking on esse points toward the unfathomable mystery that is God.

This paper examines Hermann Cohen's idiosyncratic construction of a medieval Jewish philosophical tradition, focusing primarily, though not exclusively, on his Charakteristik der Ethik Maimunis . This construction, not unlike modern accounts, is filtered through the central place of Maimonides. For Cohen, however, Maimonides' centrality is defined not by his systematization of Aristotelianism, but by his elevation of ethics over metaphysics. The ethical and pantheistic concerns of Maimonides' precursors, according to this reading, anticipate his uniqueness. Whereas Shlomo ibn Gabirol's pantheistic (...) doctrine of emanation, for example, assigned little weight to ethics, Abraham ibn Daud rebelled against such a doctrine. Ibn Daud—much like Bahya ibn Paquda and Abraham ibn Ezra—becomes part of a Jewish philosophical tradition that culminates in Maimonides' rejection of Aristotelian metaphysics. In particular, this paper examines the way in which Cohen envisaged the pre-Maimonidean philosophical tradition, putting his highly critical reading of Shlomo ibn Gabirol and his pantheistic obsession with prime matter in counterpoint with his more favorable readings of Abraham ibn Daud and Bahya ibn Paquda.

Among medieval Aristotelians, William of Ockham defends a minimalist account of artifacts, assigning to statues and houses and beds a unity that is merely spatial or locational rather than metaphysical. Thus, in contrast to his predecessors, Thomas Aquinas and Duns Scotus, he denies that artifacts become such by means of an advening ‘artificial form’ or ‘form of the whole’ or any change that might tempt us to say that we are dealing with a new thing (res). Rather, he understands (...) artifacts as per accidens composites of parts that differ, but not so much that only divine power could unite them, as in the matter and form of a proper substance. For Ockham, artifacts are essentially rearrangements, via human agency, of already existing things, like the clay shaped by a sculptor into a statue or the stick and bristles and string one might fashion into a broom. Ockham does not think that a new thing is thereby created, although his emphasis on the contribution of human artisans seems to leave questions about the ontological status of their agency open. In any case, there are no such things as natural statues, any more than substances created by human artifice. (shrink)

Hylomorphists claim that substances—human beings, oak trees, chemical compounds—are compounds of matter and form. If a house is a substance, then its matter would be some bricks and timbers and its form the structure those bricks and timbers take on. While hylomorphism is traditionally presented as a theory of change, it only treats the coming-to-be and passing-away of matter-form compounds. But many hylomorphists understand forms to be entities in their own right, as parts or constituents of substances. So, a neglected (...) question arises: how, when, and from where do forms come to be? I take up the view of one prominent and representative hylomorphist, Kathrin Koslicki, and argue that she cannot answer these questions satisfactorily. I close with a proposal for an account of the generation of forms based on machinery many hylomorphists already accept, namely, causal powers, that points to a deflationary metaphysics of form.

Aquinas’s account of the human soul is the key to his theory of human nature. The soul’s nature as the substantial form of the human body appears at times to be in tension with its nature as immaterial intellect, however, and nowhere is this tension more evident than in Aquinas’s discussion of the ‘separated’ soul. In this paper I use the Biblical story of the rich man and Lazarus (which Aquinas took to involve actual separated souls) to highlight what I (...) will call the Two-Person Problem facing his account of human identity through death and the bodily resurrection. Aquinas claims that the rational soul is neither the human being nor the human person. When the rich man’s soul says “I am in agony,” then, what is the referent of “I?” It appears that there is a human person, ‘Dives,’ who is replaced at Dives’s death by the person ‘Dives’s soul,’ who is in turn replaced at the bodily resurrection by ‘Dives,’ whom Aquinas claims is numerically identical to the original person. But this seems hopeless as an identity-preserving account of human nature. I believe that Aquinas’s account of human nature does not, as it stands, possess the resources with which to overcome this difficulty; I conclude that reconstructing a(n otherwise) Thomistic account that involves immediate bodily resurrection, although a radical approach, is the one best suited to preserving the most essential features of Aquinas’s theory.

Hylomorphism is a metaphysical theory that accounts for the unity of the material parts of composite objects by appeal to a structure or ‘form’ characterizing those parts. I argue that hylomorphism is not merely a plausible or appealing solution to problems of material composition, but a position entailed by any coherent metaphysics of ordinary material objects. In fact, not only does hylomorphism have Aristotelian defenders, but it has had independent lives in both East and West. -/- I review three contemporary (...) hylomorphic theories appeal to ‘structure’ to explain the unity of material objects. Each, however, accepts a controversial principle: that substances can have other substances as proper parts. Such a principle is implausible and severely threatens the coherence of the theory. -/- I begin by showing that Thomas Aquinas’ account of form, which does not accept that substances can have other substances as parts, gives us a more coherent version of hylomorphism. Then I argue Zhu Xi, a Song dynasty Confucian thinker, developed a non-Aristotelian hylomorphism. Unlike Aristotelians, Zhu Xi’s metaphysics was formed in opposition to Buddhist versions of skepticism and gives us reasons to think that anyone who holds a view of objects stronger than Buddhists is committed to forms. In conclusion, I show directly, by appeal to some of those same considerations from Zhu Xi, why it is that all those who believe there are unified material objects will appeal to something like a substantial form. The traditional hylomorphic picture of material composition, then, remains a plausible framework for contemporary metaphysicians – and for good reason. (shrink)

One important task of metaphysics is to answer the question of what it is for an object to exist. The first part of this book offers a systematic reconstruction and critique of contemporary views on existence. The upshot of this part is that the contemporary debate has reached an impasse because none of the considered views is able to formulate a satisfactory answer to this fundamental metaphysical question. The second part reconstructs Thomas Aquinas’s view on existence (esse) and argues that (...) it contributes a new perspective which allows us to see why the contemporary debate has reached this impasse. It has come to this point because it has taken a premise for granted which Aquinas’s view rejects, namely, that the existence of an object consists in something’s having a property. A decisive contribution of Aquinas’s theory of esse is that it makes use of the ideas of metaphysical participation and composition. In this way, it can be explained how an object can have esse without being the case that esse is a property of it. This book brings together a reconstruction from the history of philosophy with a systematic study on existence and is therefore relevant for scholars interested in contemporary or medieval theories of existence.

The thinking demonstrated by the "no form action" theory is completely new, and no one has ever used this kind of thinking to consider problems. Using no form and form as the two dimensions to describe this world is like using the x-axis and y-axis as the two dimensions of a Cartesian coordinate system in mathematics. The no form here means having no form at all. The theory established by these two dimensions is called two-dimensional theory, which avoids the shortcomings (...) of dualism and the troubles it brings to philosophy. Since no form has no form at all, we cannot study it directly or use it directly. This is also a problem recognized by past philosophers (for example, Aristotle believed that pure no form does not exist). However, I have found three no form actions (manifestation action, isolation action, and motive force action). Through these three no form actions, we can explore this world and establish a metaphysical philosophical system called no form action theory. This allows us to deeply and effectively explain consciousness, logic, dialectics, freedom, aesthetics, time, space, and so on. Not only that, as a philosophical theory, the no form action theory can also explain modern quantum mechanics, which is something that previous metaphysical philosophical systems could not do. The no form action theory is a philosophical theory established with the main line of continuously interpreting consciousness because breaking through the difficult problem of consciousness is an essential path to achieve theoretical breakthroughs. -/- The core ideas of the first five sections of the No Form Action Theory: 1, The world can be understood using a two-dimensional framework consisting of "form" and "no form". 2, There are three key "actions" of no form: isolation, motive force, and manifestation. These create the possibility for things like individual objects, change, and perception to occur. Anything can be understood from the perspective of these three no form actions, which provides three approaches for research. 3, The three no form actions provide three perspectives to understand reality - the world of isolation (macro world), the world of motive force (quantum world), and the world of manifestation (world of consciousness). 4, Current research cannot fully explain consciousness because it focuses too much on form (e.g. physical processes in the brain) while neglecting no form. Studying consciousness requires transcending to the no form dimension. 5, Through the three perspectives of no form actions (isolation, motive force and manifestation), you proposed a classification of essence, substance and subject, which helps clarify confusions in concepts. 6, Humans only have three abilities: isolation, motive force and manifestation, which limits the human way of recognizing the world. 7, The theory uses no form actions themselves to explain the theory of no form actions, which is a very innovative way of thinking. Overall, this is an original and promising theory that could significantly advance consciousness studies and other fields by providing a new conceptual framework and ways of thinking. It has substantial value and depth for the progress of philosophy. (shrink)

This thesis is about the metaphysics of logic. I argue against a view I refer to as ‘logical realism’. This is the view that the logical constants represent a particular kind of metaphysical structure, which I dub ‘logico-metaphysical structure’. I argue instead for a more metaphysically lightweight view of logic which I dub ‘logical expressivism’. -/- In the first part of this thesis (Chapters I and II) I argue against a number of arguments that Theodore Sider has given for logical (...) realism. In Chapter I, I present an argument of his to the effect that logico-metaphysical structure provides the only good explanation of the semantic determinacy of the logical constants. I argue that other explanations are possible. In Chapter II, I present another argument of his to the effect that logico-metaphysical structure is something that comes along with ontological realism: the view that there is a non-language-relative fact of the matter about what exists. I argue that the connection between logical and ontological realism is not as close as Sider makes it out to be. -/- In the second part of this thesis (Chapters III – V) I set out a positive view of the logical constants that can explain both why their meanings are semantically determinate, and why they form part of our vocabulary. On that view, the primary bearers of logical structure are propositional attitudes, and the logical constants are in our language as vehicles for the expression of logically complex propositional attitudes. In Chapter III, I set out an expressivist theory of propositional logic. In Chapter IV, I use this theory to explain how the logical connectives end up having determinate meanings. In Chapter V, I extend the expressivist theory to predicate logic. (shrink)

This paper applies a very traditional position within Natural Law Theory to Cyberspace. I shall first justify a Natural Law approach to Cyberspace by exploring the difficulties raised by the Internet to traditional principles of jurisprudence and the difficulties this presents for a Positive Law Theory account of legislation of Cyberspace. This will focus on issues relating to geography. I shall then explicate the paradigm of Natural Law accounts, the Treatise on Law, by Thomas Aquinas. From this account will emerge (...) the structure of law and the metaphysics of justice. I shall explore those aspects of Cyberspace which cause geography to be problematic for Positive Law Theory and show how these are essential, unavoidable and beneficial. I will then apply Aquinas’s structure of law and metaphysics of justice to these characteristics. From this will emerge an alternative approach to cyberlaw which has no problem with the nature of Cyberspace as it is but treats it as a positive foundation for new legal developments. (shrink)

What does it mean to be an embodied thinker of abstract concepts? Does embodiment shape the character and quality of our understanding of universals such as 'dog' and 'beauty', and would a non-embodied mind understand such concepts differently? I examine these questions through the lens of Thomas Aquinas’s remarks on the differences between embodied (human) intellects and non-embodied (angelic) intellects. In Aquinas, I argue, the difference between embodied and non-embodied intellection of extramental realities is rooted in the fact that embodied (...) and non-embodied intellects grasp different kinds of universals by means of different kinds of intelligible species (intellectual likenesses), which elicit in them different “modes” of understanding. By spelling out what exactly it means to be an embodied knower, on Aquinas’s account, I argue, we can also shed new light on his mysterious claim that the embodied intellect “turns to phantasms”—the imagination’s likenesses of individuals—in its acts of understanding.

Bartolomeo Mastri’s Disputations on Metaphysics is the single most important work on metaphysics produced in the Scotist school during the Early Modern period. This contribution guides through the work by highlighting a selection of key passages that convey an impression of its historical-literary context, its subject matter, its main motifs and scientific aims, but also its limitations. Especially, we see Mastri emphasizing the theological aspect of theology, though he in the end refrains from exploring this aspect of metaphysics within his (...) work on metaphysics. I suggest that this discrepancy between Mastri’s concept of metaphysics and his work on metaphysics showcases the difficulty of organizing this discipline during the phase of transition from the traditional commentary format typical of medieval scholasticism to the Early Modern scholastic Cursus philosophicus literature.

When developing phylogenetic systematics, the entomologist Willi Hennig adopted elements from Nicolai Hartmann’s ontology. In this historical essay I take on the task of documenting this adoption. I argue that in order to build a metaphysical foundation for phylogenetic systematics, Hennig adopted from Hartmann four main metaphysical theses. These are (1) that what is real is what is temporal; (2) that the criterion of individuality is to have duration; (3) that species are supra-individuals; and (4) that there are levels of (...) reality, each of which may be subject to different kinds of law. Reliance on Hartmann’s metaphysics allowed Hennig to ground some of the main theoretical principles of phylogenetic systematics, namely that the biological categories—from the semaphoront to the highest rank—have reality and individuality despite not being universals, and that they form a hierarchy of levels, each of which may require different kinds of explanation. Hartmann’s metaphysics thereby provided a philosophical justification for Hennig’s phylogenetic systematics, both as a theory and as a method of classification. (shrink)
