The authors of this collection fail to make clear the distinction between naturalistic and purely logical/methodological approaches to the philosophy of science. I also criticise Thomas Nickles's attempt to devise an explanatory method for discovery in science using programs that produce trial and error explorations of a domain, which he thinks replaces the need for a conjecture a refutation approach (cf. Popper and Campbell). Such programs embody undeclared conjectures in the way they are set up.

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)

REPRODUÇÃO ANIMAL: O CICLO ESTRAL DE BOVINOS LEITEIROS – Desenvolvimento Folicular, Corpo Lúteo e Etapas do Estro ANIMAL REPRODUCTION: THE OESTROUS CYCLE OF DAIRY BOVINES -Follicular Development, Corpus Luteum and Stages of Estrus Apoio: Emanuel Isaque Cordeiro da Silva Departamento de Zootecnia da UFRPE E-mail: [email protected] WhatsApp: (82)98143-8399 FISIOLOGIA CLÍNICA DO CICLO ESTRAL DE BOVINOS LEITEIROS 1. RESUMO A fêmea bovina apresenta ciclos estrais em intervalos de 19 a 23 dias e estes só são interrompidos durante a gestação ou devido (...) a alguma patologia. O estro é o período de aceitação da cópula e tem uma duração de 8 a 18 horas. Durante o metaestro ocorre a ovulação e se desenvolve o corpo lúteo. O diestro é o estágio mais longo do ciclo e é caracterizado pela presença de um corpo lúteo. Se a gestação não for estabelecida, o endométrio segrega prostaglandina F2α(PGF2α) o que induz a luteólise, reiniciando assim um novo ciclo. 2. EIXO HIPOTÁLAMO-HIPÓFISE-OVÁRIO As hormonas são substâncias produzidas por diferentes células do organismo que exercem funções específicas em outras células (células brancas). Algumas hormonas atuam na mesma célula que a secreta (atividade autocrina), outras nas células vizinhas (atividade parácrina) e outras são transportadas pelo sangue e exercem a sua função em células de outros órgãos (atividade endócrina). Existem outros tipos de hormônios que comunicam a diferentes indivíduos e são conhecidos como feromônios. Os feromônios regulam diferentes funções, entre as quais se destacam as reprodutivas. O hipotálamo encontra-se na base do cérebro, é formado por núcleos pares de neurônios e comunica-se com a hipófise através de um sistema circulatório especializado conhecido como sistema porta-hipotálamo-hipofisário. Os neurônios da área ventromedial e da área pré-óptica do hipotálamo secretam a hormona libertadora das gonadotropinas (GnRH), que por sua vez chega à hipófise através do sistema porta-hipotálamo-hipofisário e estimula a secreção da hormona luteinizante (LH) e da hormona folículo estimulante (FSH). A LH mantém um padrão de secreção paralelo à secreção da GnRH; ou seja, uma parcela de GnRH corresponde a uma parcela de LH, ao contrário da FSH que tem uma produção basal elevada inibida pelo estradiol e inibina, por este motivo, a sua secreção não apresenta um padrão pulsante semelhante à LH. A GnRH tem duas formas de secreção: a primeira é pulsante ou tônica, regulada por estímulos externos (fotoperíodo, bioestimulação, amamentação) e por estímulos internos (metabolitos, hormonas metabólicas, hormonas sexuais); a segunda forma é pré-ovulatória ou cíclica e é estimulada pelos estrogênios durante o estro e inibida pela progesterona. A secreção de alguns hormônios, bem como diversos processos fisiológicos, são sincronizados com a duração do dia e da noite (ritmos endógenos). A luz é percebida pelos fotorreceptores da retina e o sinal luminoso chega à glândula pineal através de conexões neuronais (trato retino-hipotalâmico). Na glândula pineal, o estímulo produzido pela luz inibe a síntese da melatonina. Desta forma, a duração do dia e da noite (fotoperíodo) é registada pelas variações nas concentrações da melatonina. Na vaca, sabe-se que o fotoperíodo influencia alguns processos reprodutivos, embora não seja, em sentido estrito, uma espécie com um padrão reprodutivo sazonal. Os feromônios sexuais são excretados através da urina, fezes e fluidos corporais; eles são percebidos pelo epitélio olfatório e órgão vomeronasal. Posteriormente, algumas vias nervosas, estimulam no hipotálamo a frequência dos pulsos de secreção da GnRH. A exposição a feromonas femininas provoca no macho um aumento na frequência de secreção do LH e isto por sua vez aumenta as concentrações de testosterona. Os feromônios masculinos induzem na fêmea um aumento da frequência de secreção do LH, estimulando o crescimento folicular e a secreção de estradiol. A estimulação sexual provocada pelo macho ou pela fêmea é denominada bioestimulação. As alterações na condição corporal estão positivamente correlacionadas com as concentrações séricas de insulina, fator de crescimento semelhante à insulina tipo I (IGF- I) e leptina. Assim, quanto maior a classificação da condição corporal, maior é a concentração sérica destas hormonas, que atuam como sinais que chegam ao hipotálamo e modificam a frequência de secreção da GnRH. Por exemplo, a transição do anestro para a ciclicidade coincide com um aumento da condição corporal e das concentrações de insulina, IGF- I e leptina (figura 1). Figura 1. A transição do anestro para a ciclicidade coincide com um aumento da condição corporal e das concentrações de insulina, IGF- I e leptina. Estas hormonas atuam como sinais que chegam ao hipotálamo e aumentam a frequência de secreção da GnRH. Fonte: GALINA, et al. 2008. Os estrogênios podem ter um feedback positivo ou negativo sobre a secreção da GnRH, o que depende da fase do ciclo reprodutivo. Em animais pré-púberes e em anestro pós-parto, os estrogênios inibem a secreção de GnRH, mas durante o período de proestro e estro há uma estimulação para a secreção de GnRH. A progesterona reduz a secreção da GnRH, bem como a resposta da hipófise à GnRH, inibindo assim a maturação folicular e a ovulação. Por esta razão, a progesterona foi utilizada com sucesso como contraceptivo em humanos e para o controle artificial da reprodução em animais domésticos (figura 2). Figura 2. Retroalimentação entre o hipotálamo, hipófise e o ovário. A GnRH estimula na hipófise a síntese e secreção de LH e FSH. Na fase pré-púbere e no anestro pós-parto, os estrogênios inibem a secreção de GnRH, enquanto no proestro e estro, estimulam-na. A progesterona inibe a secreção da GnRH e diminui a resposta da hipófise à GnRH. Os estrogênios e a inibina suprimem a secreção de FSH diretamente na hipófise. Fonte: GALINA, et al. 2008. Os neurônios secretores da GnRH não têm receptores para estrogênios nem progesterona, pelo que estas hormonas não têm forma de regular diretamente a secreção da GnRH. Existe um grupo de neurônios hipotalâmicos que exprimem o gene Kiss-1 que codifica o peptídeo kisspeptina. Os neurônios secretores da GnRH têm receptores para este peptídeo, de modo que a kisspeptina fornece a informação aos neurônios secretores da GnRH em relação às concentrações de hormônios sexuais. A kisspeptina é um potente estimulador (secretagogo) da secreção da GnRH e é muito provável que nos próximos anos venha a fazer parte dos recursos hormonais para o controle artificial da reprodução, não só nos bovinos, mas em todas as espécies domésticas. 3. DESENVOLVIMENTO FOLICULAR O ovário é responsável pela produção de ovócitos e pela síntese de hormônios sexuais, estrogênios e progesterona, que promovem e regulam a fertilização do ovócito e a manutenção da gestação. O ovócito encontra-se no interior do folículo ovárico rodeado por células granulosas que participam de forma ativa no seu crescimento e maturação. As experiências in vitro demonstram a dependência dos ovócitos das células da granulosa, assim, quando os ovócitos são induzidos a amadurecer devem estar rodeados por várias camadas de células da granulosa para que este processo seja bem sucedido, caso contrário, não adquirem o potencial para desenvolver um embrião. Embora as células da teca interna não estejam em contato direto com o ovócito, seu papel na maturação deste o exercem mediante a produção de andrógenos, mesmos que são convertidos em estrogênios pelas células da granulosa. Além disso, as células da teca favorecem o estabelecimento da rede capilar que apoia o desenvolvimento folicular. Por outro lado, os novos conhecimentos indicam que o ovócito não é um elemento passivo no desenvolvimento folicular, mas regula a função das células foliculares; o que significa que ele próprio participa na criação de um microambiente ideal para a sua maturação. Além disso, é possível que o ovócito tenha um papel na ativação do desenvolvimento dos folículos primordiais. A fêmea bovina nasce com aproximadamente 200 mil folículos, dos quais muito poucos se ativam e iniciam seu crescimento, e a maior parte deles sofre atresia em diferentes etapas de desenvolvimento. Ao nascimento, os folículos estão na fase mais elementar e são conhecidos como folículos primordiais. Posteriormente estes folículos se ativam e se transformam em folículos primários e secundários; até este momento os folículos não têm antro (etapa pré-antral) e seu desenvolvimento é independente das gonadotropinas. Quando os folículos formam o antro são conhecidos como folículos terciários e seu desenvolvimento é dependente das gonadotropinas (etapa antral). O crescimento folicular no estágio antral ocorre em forma de ondas e cada onda começa com um aumento nos níveis de FSH, o qual promove o crescimento de um grupo de cinco a seis folículos (~4 mm de diâmetro); este processo é conhecido como recrutamento. Subsequentemente, um único folículo continua a crescer (folículo dominante), o que provoca um aumento das concentrações de estrogênios e inibina, uma diminuição das concentrações de FSH e atresia dos folículos subordinados, pois eles dependem totalmente desta hormona, enquanto o folículo dominante continua o seu desenvolvimento estimulado pela LH. O folículo dominante perdura de quatro a seis dias e se não chega a ovular, sofre atresia. Após a atresia do folículo dominante, diminuem-se os níveis de estrogênio e inibina, observa-se um aumento das concentrações de FSH e inicia-se uma nova onda folicular. O folículo dominante que está presente quando o corpo lúteo sofre regressão, continua seu desenvolvimento e ovula, em resposta ao pico pré-ovulatório de LH. Além de promover a liberação do ovócito, a secreção pré-ovulatória de LH regula a formação do corpo lúteo a partir das células foliculares, processo conhecido como luteinização. Durante o ciclo estral são apresentadas de duas a três ondas foliculares. As vacas com três ondas foliculares têm uma fase lútea mais longa e, consequentemente, um ciclo estral mais longo, de 22 a 23 dias; enquanto as vacas com duas ondas apresentam um ciclo estral de 18 a 21 dias. Nas vacas leiteiras, cerca de 70% apresentam duas ondas foliculares, enquanto 30% exibem três ondas (figura 3 e 4). Nas vacas com duas ondas foliculares, o período de dominação folicular é maior do que nas de três ondas. O tempo de dominação influencia o potencial dos ovócitos para desenvolver um embrião viável; assim, a porcentagem de concepção é menor quando ovulam folículos que tiveram mais dias de dominação dos que quando ovulam folículos com menor tempo de dominação (figura 5). Figura 5. O crescimento folicular no estágio antral ocorre na forma de ondas. Cada onda começa com um aumento nas concentrações de FSH, o que promove o recrutamento de cinco a seis folículos (~4 mm de diâmetro). Posteriormente um único folículo continua crescendo (folículo dominante), enquanto seus companheiros (subordinados) sofrem atresia. O folículo dominante perdura de quatro a seis dias e se não chega a ovular, sofre atresia. Após a atresia do folículo dominante observa-se um aumento das concentrações de FSH, iniciando-se uma nova onda folicular. 3.1 Ovulação múltipla Nos últimos anos tem-se observado um aumento na proporção de vacas com ovulação múltipla (20% x 1% em novilhas), o que tem provocado um aumento da proporção de partos gêmeos (8% x 1% em novilhas). A frequência de vacas com ovulação múltipla está associada com a alta produção de leite; de modo que, as vacas que produzem menos de 40 kg mostram 6% de ovulações múltiplas e aquelas que produzem mais de 50 kg alcançam até 50%. A causa deste fenômeno ainda é obscura, contudo, observaram-se diferenças nas concentrações de FSH, de tal forma que as vacas que desenvolvem de dois a três folículos dominantes numa onda folicular, apresentam níveis de FSH mais elevados que as vacas que têm apenas um folículo dominante. Em vacas em lactação, a concentração de progesterona é baixa devido ao aumento do metabolismo hepático, o que aumenta a sua taxa de eliminação. Foi observado que as vacas que tiveram uma fase lútea com níveis de progesterona mais elevados, no ciclo anterior à inseminação, apresentam menos ovulações múltiplas em comparação com as vacas que tiveram níveis de progesterona mais baixos. Propõe-se que as baixas concentrações de progesterona permitam um aumento da frequência de secreção da GnRH e, consequentemente, da LH e da FSH, favorecendo a predominância múltipla e, eventualmente, a ovulação de mais de um folículo. Nos rebanhos leiteiros, as gestações gêmeas não são desejáveis porque aumenta o risco de perda da gestação e, se esta chegar ao término, haverá o risco de perda da gestação e, se esta for concluída, o risco de distorcia é consideravelmente mais elevado (figuras 6, 7, 8 e 9). Figura 6. As baixas concentrações de progesterona sérica nas vacas em lactação permitem um aumento da frequência de secreção da GnRH, bem como o aumento da LH e da FSH. Isto favorece a dominação múltipla e eventualmente a ovulação de mais de um folículo. Esta figura mostra a dominância de dois folículos em cada onda folicular (codominância). Figura 7.

Ovários de uma vaca leiteira com dois corpos hemorrágicos. Fonte: Acervo pessoal do autor. IFPE, 2017-18. 4. DESENVOLVIMENTO E CONTROLE DA FUNÇÃO DO CORPO LÚTEO Quando o folículo dominante completa sua maturação, ele produz níveis de estrogênio suficientes para provocar a liberação máxima da GnRH, o que desencadeia o pico pré-ovulatório da LH. Esta secreção de LH provoca a ovulação e inicia as mudanças para que o folículo se transforme em um corpo lúteo, processo conhecido como luteinização. A luteinização compreende todas as mudanças morfológicas, endócrinas e enzimáticas que ocorrem no folículo ovulatório até que este se transforme num corpo lúteo. O processo de luteinização começa a partir da elevação pré-ovulatória de LH; mesmo antes da ovulação. A luteinização do folículo dominante (≥8 mm de diâmetro) pode ser induzida hormonalmente pela injeção de GnRH ou gonadotropina coriónica humana (hCG). A ovulação ocorre em média 30 horas após o pico pré-ovulatório de LH. A secreção pré-ovulatória de LH desencadeia a liberação de enzimas proteolíticas e de mediadores da inflamação na parede folicular, as quais degradam o tecido conjuntivo e ocasionam morte celular. Posteriormente, a PGF2α induz contrações da teca externa, levando à ruptura folicular e à expulsão do ovócito. Após a ovulação, as células da teca interna e da granulosa migram e distribuem-se nas paredes do folículo. As células da teca interna se diferenciam e se multiplicam em células lúteas pequenas, enquanto que as células da granulosa se hipertrofiam e dão origem às células lúteas grandes. Estas alterações são facilitadas pela ruptura da membrana basal que separa a camada celular da granulosa da teca interna. Em forma paralela começa a formação de uma ampla rede de capilares que se distribuem em todo o corpo lúteo em formação, e chegam a constituir até 20% do volume desta estrutura (figuras 10 e 11). A progesterona é o principal produto de secreção do corpo lúteo. No quinto dia do ciclo estral, as concentrações séricas desta hormona são superiores a 1 ng/ ml, indicando que o corpo lúteo adquiriu a sua plena funcionalidade. A progesterona atua basicamente sobre os órgãos genitais da fêmea, sendo responsável pela preparação do útero para o estabelecimento e manutenção da gestação. Na mucosa do oviduto e do útero, estimula a secreção de substâncias que promovem o desenvolvimento do embrião, até que este comece a nutrir-se através da placenta. A progesterona suprime a resposta imunitária do útero, o que é necessário para tolerar o embrião, já que este é um tecido estranho para a vaca. Além disso, a progesterona evita as contrações do útero, fecha o colo do útero e modifica as características do muco cervical, tornando-o mais viscoso, impedindo a passagem de agentes estranhos para o interior do útero. Na glândula mamária estimula o desenvolvimento do sistema alveolar, preparando-a para a síntese e a secreção de leite. 5. REGRESSÃO DO CORPO LÚTEO A regressão lútea é um processo ativo ocasionado pela secreção uterina da PGF2α. O mecanismo pelo qual se inicia a síntese e secreção da PGF2α depende de uma interação entre o corpo lúteo, os folículos e o útero. Os estrogênios produzidos no folículo dominante desempenham um papel importante no início da secreção de PGF2α, uma vez que promovem a síntese de receptores para oxitocina. Além disso, os estrogénios estimulam no endométrio a produção da fosfolipase A e da ciclooxigenase; enzimas indispensáveis para a síntese da PGF2α. Durante o ciclo estral, a progesterona inibe a síntese da PGF2α através da supressão da formação de receptores para o estradiol. Após um período de 12 a 14 dias de exposição à progesterona, as células endometriais tornam-se insensíveis à progesterona. Quando isso ocorre, as células endometriais sintetizam receptores para estradiol, permitindo que o estradiol produzido no folículo dominante estimule a síntese de receptores para oxitocina. Neste momento, o endométrio está pronto para sintetizar e secretar PGF2α, em resposta ao estímulo da oxitocina. A primeira secreção de oxitocina é de origem hipotalâmica, o que desencadeia o primeiro pulso de PGF2α. Os seguintes episódios de PGF2α são induzidos pela oxitocina produzida no corpo lúteo. A PGF2α é secretada em episódios (pulsos) com intervalos de seis a oito horas, sendo necessários cinco a seis episódios para a luteólise ocorrer. Se a PGF2α não seguir este padrão de secreção, a regressão do corpo lúteo falhará. Além da PGF2α de origem uterina, o corpo lúteo também produz PGF2α, que aumenta o efeito luteolítico. A falta de sensibilidade à PGF2α observada nos corpos lúteos imaturos (primeiros cinco dias após a ovulação) deve-se ao fato de, neste período, o corpo lúteo ainda não produzir PGF2α (figura 12, 13 e 14). 6. ETAPAS DO CICLO ESTRAL O ciclo estral é dividido em quatro etapas bem definidas. 6.1 Estro Neste estágio a fêmea aceita a cópula ou a monta de outra vaca. O estro é provocado pelo aumento significativo das concentrações de estradiol produzido pelo folículo pré-ovulatório e pela ausência de um corpo lúteo. A duração desta etapa é de 8 a 18 horas. 6.2 Metaestro O metaestro é a etapa posterior ao estro, tem uma duração de quatro a cinco dias. Durante esta etapa ocorre a ovulação e se desenvolve o corpo de lúteo. Após a ovulação, observa-se uma depressão no lugar ocupado pelo folículo ovulatório (depressão ovulatória) e, posteriormente, se desenvolve o corpo hemorrágico (corpo lúteo em processo de formação). Durante o metaestro, as concentrações de progesterona começam a aumentar até atingirem níveis superiores a 1 ng/ml, momento a partir da qual considera-se que o corpo lúteo atingiu a maturidade. O momento em que as concentrações de progesterona são superiores a 1 ng/ml toma-se como critério fisiológico a determinação do fim do metaestro e o início do diestro. Um evento hormonal que se destaca neste período consiste na apresentação do pico pós-ovulatório de FSH, o qual desencadeia a primeira onda de desenvolvimento folicular. Algumas vacas apresentam sangramento conhecido como sangramento metaestral (figura 15). 6.3 Diestro O diestro é o estágio de maior duração do ciclo estral, de 12 a 14 dias. Durante este estágio o corpo lúteo mantém sua plena funcionalidade, o que se reflete em concentrações sanguíneas de progesterona, maiores que 1 ng/ml. Além disso, nesta fase, pode-se encontrar folículos de tamanho diferente devido às ondas foliculares. Após 12-14 dias de exposição à progesterona, o endométrio começa a secretar PGF2α em um padrão pulsátil, ao qual termina com a vida do corpo lúteo e com o diestro. Em termos endócrinos, quando o corpo lúteo perde a sua funcionalidade, ou seja, quando as concentrações de progesterona diminuem abaixo de 1 ng/ml, finaliza-se o diestro e começa o proestro. Convém mencionar que durante esta fase, a LH é secretada com uma frequência muito baixa e a FSH tem incrementos responsáveis pelas ondas foliculares. 6.4 Proestro O proestro caracteriza-se pela ausência de um corpo lúteo funcional e pelo desenvolvimento e maturação do folículo ovulatório. O proestro na vaca dura de dois a três dias. Um evento hormonal característico desta etapa é o aumento da frequência dos pulsos de secreção de LH que levam à maturação final do folículo ovulatório e ao aumento do estradiol sérico, que desencadeia o estro. Para além da classificação do ciclo estral acima descrita, existe outra que divide o ciclo em duas fases: progestacional (lútea) e estrogênica (folicular). A fase progestacional inclui o metaestro e o diestro, e a fase estrogênica ao proestro e estro (figura 16). Figura 16. Etapas do ciclo estral. Adaptado e elaborado a partir de FERREIRA, 2010. 7.

Abstract: Samples of LaxSr1-xMnO3 (x = 0.5, 0.55, 0.6, 0.66, and 0.7) were prepared by the citrate-nitrate autocombustion method. The prepared nano-particles were investigated and characterized using X-Ray diffraction (XRD) and Transmission Electron Microscopy (TEM) to confirm the formation of the samples in single phase without any impurities and to calculate the particle size. The magnetic susceptibility χM was measured as a function of temperature and magnetic field intensity. From χM(T) and M(H) the saturation magnetization (Ms), remanent magnetization (Mr) and (...) coercivity (Hc) of the samples were estimated. The correlation among physical properties and the ratio of divalent cation substitution was discussed and reported to shed more light on technological applications of the investigated samples.

Abstract: Smoke detectors are critical devices for early fire detection and life-saving interventions. This research paper explores the application of Artificial Neural Networks (ANNs) in smoke detection systems. The study aims to develop a robust and accurate smoke detection model using ANNs. Surprisingly, the results indicate a 100% accuracy rate, suggesting promising potential for ANNs in enhancing smoke detection technology. However, this paper acknowledges the need for a comprehensive evaluation beyond accuracy. It discusses potential challenges, such as overfitting, dataset size, (...) and class imbalance, and presents strategies employed to address these issues. Additionally, the paper emphasizes the importance of alternative evaluation metrics, including precision, recall, and F1-score, to assess the model's performance comprehensively. Detailed information regarding the model architecture, data preprocessing, and hyperparameter tuning is provided to enhance the reproducibility of the research. The study also discusses ethical considerations and the implications of false positives and false negatives in smoke detection applications. While achieving 100% accuracy is a notable accomplishment, this paper calls for cautious interpretation and further validation in real-world settings. It concludes by highlighting areas for future research and improvement in smoke detection technology, emphasizing the need for practical deployment and the reduction of false alarms. (shrink)

Psychopathy refers to a range of complex behaviors and personality traits, including callousness and antisocial behavior, typically studied in criminal populations. Recent studies have used self-reports to examine psychopathic traits among noncriminal samples. The goal of the current study was to examine the underlying factor structure of the Self-Report of Psychopathy Scale–Short Form (SRP-SF) across complementary samples and examine the impact of gender on factor structure. We examined the structure of the SRP-SF among 2,554 young adults from three undergraduate samples (...) and a high-risk young adult sample. Using confirmatory factor analysis, a four-correlated factor model and a four-bifactor model showed good fit to the data. Evidence of weak invariance was found for both models across gender. These findings highlight that the SRP-SF is a useful measure of low-level psychopathic traits in noncriminal samples, although the underlying factor structure may not fully translate across men and women.

For the Intentionalist, utterance content is wholly determined by a speaker’s meaning-intentions; the sentence uttered serves merely to facilitate the audience’s recovering these intentions. We argue that Intentionalists ought to be Particularists, holding that the only “principles” of meaning recovery needed are those governing inferences to the best explanation; “principles” that are both defeasible and, in a sense to be elaborated, variable. We discuss some ways in which some theorists have erred in trying to tame the “wild west” of pragmatics (...) and context-sensitivity -- including recent work that makes essential appeal to the information structure of a discourse -- and in so doing, offer a general recipe for defending the Particularist picture of utterance content and its recovery that we favor.

One of the standard approaches to the metaphysics of personal identity has some counter-intuitive ethical consequences when combined with maximising consequentialism and a plausible doctrine about aggregation of consequences. This metaphysical doctrine is the so-called ‘multiple occupancy’ approach to puzzles about fission and fusion. It gives rise to a new version of the ‘utility monster’ problem, particularly difficult problems about infinite utility, and a new version of a Parfit-style ‘repugnant conclusion’. While the article focuses on maximising consequentialism for simplicity, the (...) problems demonstrated apply more widely to a range of ethical views, especially flavours of consequentialism. This article demonstrates how these problems arise, and discusses a number of options available in the light of these problems for a consequentialist tempted by a multiple occupancy metaphysics.

In performing an act of assertion we are sometimes responsible for more than the content of the literal meaning of the words we have used, sometimes less. A recently popular research program seeks to explain certain of the commitments we make in speech in terms of responsiveness to the conversational subject matter. We raise some issues for this view with the aim of providing a more general account of linguistic commitment: one that is grounded in a more general action‐theoretic notion (...) of responsibility.

Propositions are the things we believe, intend, desire, and so on, but discussions are often less precise than they could be and an important driver of this deficiency has been a focus on the objects but a neglect of the attitudinal relations we bear to them. In what follows, we will offer some thoughts on what it means for a proposition to be the object of an attitude and we will argue that an important part of the story lies with (...) the attitude relations rather than the propositions. As we will see there are infinitely many relations we might bear to a proposition, but the propositional attitude relations are special amongst them. Accounting for what makes them special will be an important component in the discussion that follows. We will argue that once one appreciates certain facts about propositional attitude relations, various claims that metaphysicians often make regarding propositions themselves begin to look undermotivated. In fact, many views on the metaphysical nature of propositions come to look like plausible candidates for being that to which our propositional attitudes relate us. As will emerge, we will see that the principle role of propositions in the theory of mind is simply to keep track of how our attitudinal states represent things as being. But, we argue, in order to do this work, very few constraints must be placed on the nature of propositions themselves. In particular, contra much of the recent work on the metaphysics of propositions, they need not represent nor must they be structured. In light of these observations, we conclude by sketching our own favored minimalist view of propositions. (shrink)

David Lewis (1974, 1994/1999) proposed to reduce the facts about mental representation to facts about sensory evidence, dispositions to act, and rationality. Recently, Robert Williams (2020) and Adam Pautz (2021) have taken up and developed Lewis’s project in sophisticated and novel ways. In this paper, we aim to present, clarify, and ultimately object to the core thesis that they all build their own views around. The different sophisticated developments and defenses notwithstanding, we think the core thesis is vulnerable. We pose (...) a dilemma by considering the two sides of a current epistemological controversy over the relation between evidence and rational belief: permissivism vs. uniqueness. As we argue, the prospects for the Lewisian project look dim when either supposition is clearly made. (shrink)

It has recently been argued that our use of vague language poses an intractable problem for any account of content and communication on which (i) the things we assert are propositions and (ii) understanding an assertion requires recognizing which proposition the speaker asserted. John MacFarlane has argued that this problem concerning vague language is itself a species of an even more general problem for such traditional accounts – the problem posed by “felicitous” underspecification. Repurposing certain ideas from Allan Gibbard, MacFarlane (...) offers a novel theory of vagueness, plan-expressivism, as an account that can handle both vagueness and such underspecification in communication. -/- In this paper, I argue that despite its many virtues, plan-expressivism fails as a general account of meaning and communication. In particular, I show that when it comes to the problem of felicitous underspecification, plan-expressivism fares no better than the more traditional accounts of content and communication it is intended to replace. Along the way, I argue that the problem of felicitous underspecification puts considerable pressure on an assumption that is at the core of both plan-expressivism and the accounts of its more traditionalist rivals - namely, that in cases of successful linguistic communication, we must always be able to find something -- whether a propositional content or a conversational update -- that the speaker is intending to share with her audience.

In ‘What Reference Has to Tell Us about Meaning’, Stephen Schiffer argues that many of the objects of our beliefs, and the contents of our assertoric speech acts, have what he calls the relativity feature. A proposition has the relativity feature just in case it is an object-dependent proposition ‘the entertainment of which requires different people, or the same person at different times or places, to think of [the relevant object] in different ways’ (129). But as no Fregean or Russellian (...) proposition can possibly have such a feature, we must either (i) give up on these traditional theories of propositional content in favor of an account that can allow for the relativity feature, or else (ii) explain why the things we believe, and say, oftentimes seem to have this feature even though they, in fact, do not. Schiffer pursues the former option; in this essay, I pursue the latter. (shrink)

Your belief that Obama is a Democrat would not be the belief that it is if it did not represent Obama, nor would the pain in your ankle be the state that it is if, say, it felt like an itch. Accordingly, it is tempting to hold that phenomenal and representational properties are essential to the mental states that have them. But, as several theorists have forcefully argued (including Kripke (1980) and Burge (1979, 1982)) this attractive idea is seemingly in (...) tension with another equally attractive thesis, namely, the token-identity thesis; the thesis according to which every mental state token is identical with some or other token physical state. In this paper, we show that these seemingly incontrovertible essentialist intuitions are in fact compatible with “token physicalism” regarding the mental. Given a suitably plentitudinous ontology of objects, we argue that there are physical things with which our token mental states can be identified. This is preferable to existing views that give up the essentiality claims or simply reject the token-identity thesis. (shrink)

Confirmation and falsification are different strategies for testing theories and characterizing the outcomes of those tests. Roughly speaking, confirmation is the act of using evidence or reason to verify or certify that a statement is true, definite, or approximately true, whereas falsification is the act of classifying a statement as false in the light of observation reports. After expounding the intellectual history behind confirmation and falsificationism, reaching back to Plato and Aristotle, I survey some of the main controversial issues and (...) arguments that pertain to the choice between these strategies: the Raven Paradox, the Duhem/Quine problem and the Grue Paradox.

In this paper, we outline an approach to giving extensional truth-theoretic semantics for what have traditionally been seen as opaque sentential contexts. We outline an approach to providing a compositional truth-theoretic semantics for opaque contexts which does not require quantifying over intensional entities of any kind, and meets standard objections to such accounts. The account we present aims to meet the following desiderata on a semantic theory T for opaque contexts: (D1) T can be formulated in a first-order extensional language; (...) (D2) T does not require quantification over intensional entities­i.e., meanings, propositions, properties, relations, or the like­in its treatment of opaque contexts; (D3) T captures the entailment relations that hold in virtue of form between sentences in the language for which it is a theory; (D4) T has a finite number of axioms. If the approach outlined here is correct, it resolves a longstanding complex of problems in metaphysics, the philosophy of mind and the philosophy of language. (shrink)

Rene Descartes (1596 – 1650) is considered the founder of modern philosophy. Profoundly influenced by the new physics and astronomy of Kepler and Galileo, Descartes was a scientist and mathematician whose most long-lasting contributions in science were the invention of Cartesian coordinates, the application of algebra to geometry, and the discovery of the law of refraction, what we now call Snell’s law.His most important books on philosophy were The discourse on method(1637) and The meditations(1642). Descartes’ writings display an exemplary degree (...) of clarity and an aversion to pedantry. I explore Descartes' break with Aristotle, but also shine a light on the intellectual continuity Descartes had with Aristotle's thought. I also draw attention to some overlooked but interesting possibilities for an experimental test of a dualistic theory of mind. (shrink)

This chapter argues that while quotation marks are polysemous, the thread that runs through all uses of quotation marks that involve reference to expressions is pure quotation, in which an expression formed by enclosing another expression in quotation marks refers to that enclosed expression. We defend a version of the so-called disquotational theory of pure quotation and show how this device is used in direct discourse and attitude attributions, in exposition in scholarly contexts, and in so-called mixed quotation in indirect (...) discourse and attitude attributions. We argue that uses of quotation marks that extend beyond pure quotation have two features in common. First, the expressions appearing in quotation marks are intended to be understood, and that they are intended to be understood is essential to the function that such quotations play in communication, though this does not always involve the expressions contributing their extensional properties to fixing truth conditions for the sentences in which they appear. Second, they appeal to a relation to the expression appearing in quotation marks that plays a role in determining the truth conditions of the sentences in which they appear. (shrink)

A brief intellectual biography of Sir Karl Popper.

In the film classic Blade Runner, the story explores the notion of personal identity through that of carefully crafted androids. Can an android have a personality; can androids be persons? The title of the original story by Philip K. Dick is Do Androids Dream of Electric Sheep? The story suggests that our sense of being a person depends on our having memories that connect us with our childhood. In the movie, the androids are only a couple of years old, but (...) have adult bodies. To complete them as persons they are given simulated memories of childhood. Some psychiatrists have decided that even humans dream only of electric sheep. I explore how Popper’s world 3 can help to defend a notion of personhood that can be used to criticize the thesis that persons are simply complex physical processes and that all their serious life-problems can be conceptualised as a form of physical illness.

It is facile and factually incorrect to represent suicide terrorists as simply seeking mass destruction, as demented or believing that they will be rewarded by "seventy-two virgins in paradise". In my book The Myth of the Closed Mind: Understanding How and Why People are Rational I felt it was important to deal with the issue of terrorism by consulting explanatory theories of human behaviour and the substantial research on the strategic pattern of terrorist incidents over the decades, led principally by (...) Professor Robert Pape of Chicago University. -/- To defeat your enemy, you must first understand him. Strangely, we must first grant that, though morally depraved, terrorists are rational: they concoct and execute detailed plans with definite strategic goals in mind. Only once we have granted the terrorist a rational mind can we, in the end, create peace. My argument is that while religion may have a small role in terrorism, it is principally politics, or the logic of territorial control, that is the key to understanding the threat we face. -/- This extract from my book is principally about Al Qaeda, but a similar analysis applies to ISIS, the current greatest threat to our peace in the west. -/- The strategic goal of Al Qaeda was simply to repulse what they saw as foreign intervention. ISIS has the same goal, but in order to continue its growth as a state in the sense of a monopoly of coercion over a given geographical area. -/- ISIS, a rogue state that arose in ungoverned space created unintentionally by foreign intervention in Iraq, is now lashing out at foreign governments that have severely shrunk the territory ISIS occupies. Before October 2015, ISIS confined its terrorism to the goal of extending its territory in Iraq and Syria, and there were no significant ISIS-led or inspired suicide terrorist attacks outside Iraq and Syria. But now, as their territory collapses, they are attacking the countries that have strangled their control of territory in Iraq and Syria: the coalition of western governments – Britain, Belgium, Canada, France, Morocco, Turkey, Russia, the U.S.A. and others – exactly the countries that have recently seen an explosion of suicide terrorism.

A brief survey of British philosophy of education.

The answer given to 'the problem of evil' in the Bible that apologists, theologians, and philosophers have not recognized or understood, having sought for answers to the problem outside the sacred texts wherein alone the unequivoval answer can be found, if only one puts together the relevant texts, as for instance, the book of Job, the book of Isaiah concerning prophecies related to the return of Christ, the book of Ezekiel, the 24th chapter of Matthew, certain passages from the letters (...) of Paul, and the book of Reveation. The central theme in this work is that evil exists now not by reason of God's presence, but by reason of God's absence. We have been left to our own devices. The reason for this is very clear in these texts, and the work spells this out in no uncertain terms, and once this reason is made fully apparent, and undeniable, it will leave no viable excuse for anyone to reject the return of the King of kings, and His eternal rule over all as the Prince of peace.

No evangelistic erroneous network of ideas can guarantee the satisfaction of these two demands : (1) propagate the network without revision and (2) completely insulate itself against losses in credibility and adherents through criticism. If a network of ideas is false, or inconsistent or fails to solve its intended problem, or unfeasible, or is too costly in terms of necessarily forsaken goals, its acceptability may be undermined given only true assumptions and valid arguments. People prefer to adopt ideologies that (i) (...) are logically consistent, (ii) are more truth-like and of higher information content than their rivals, (iii) are systematically organised, (iv) solve their problems better than their rivals, (v) do not contain unfeasible demands, and (vi) do not contain uneconomic demands. Truth and validity therefore act as Darwinian-like filters on ideologies. Using Popper's notion of situational analysis and with reference to Darwinian evolution, considered as a special case of the former, and Bartley's theory of comprehensively critical rationalism I argue that a propagandist cannot guarantee his message or his movement from sound criticism. All positions are in a methodological sense open to argument. Moreover, the logic of a propagandist's situation constrains him into making his message and himself open to criticism in order to maximize its chances of being propagated through the population. But he then loses control of the message in two respects. Firstly, his audience are disposed to select from the competing ideas they encounter those that satisfy (i) to (vi) because of man's evolutionary history. Secondly, he cannot guarantee protection from criticism even a privileged section of his message because he cannot predict in a systematic way what logical repercussions each protective reformulation of the ideology will have on other sections of the ideology and what criticism the ideology will encounter. He cannot do the latter because of certain logical properties of theories that endow them with unfathomable depths. Marxism and Freudianism serve as case studies, especially for the analysis of Popper's notion of the immunizing stratagem, a methodological/logical device that is supposed to save theories from criticism. "Immunizing stratagems" either abandon the ideology they are meant to protect or seriously lower its chances of being reproduced. (shrink)

A sorites argument is a symptom of the vagueness of the predicate with which it is constructed. A vague predicate admits of at least one dimension of variation (and typically more than one) in its intended range along which we are at a loss when to say the predicate ceases to apply, though we start out confident that it does. It is this feature of them that the sorites arguments exploit. Exactly how is part of the subject of this paper. (...) The majority of philosophers writing on vagueness take it to be a kind of semantic phenomenon. If we are right, they are correct in this assumption, which is surely the default position, but they have not so far provided a satisfactory account of the implications of this or a satisfactory diagnosis of the sorites arguments. Other philosophers have urged more exotic responses, which range from the view that the fault lies not in our language, but in the world, which they propose to be populated with vague objects which our semantics precisely reflects, to the view that the world and language are both perfectly in order, but that the fault lies with our knowledge of the properties of the words we use (epistemicism). In contrast to the exotica to which some philosophers have found themselves driven in an attempt to respond to the sorites puzzles, we undertake a defense of the commonsense view that vague terms are semantically vague. Our strategy is to take fresh look at the phenomenon of vagueness. Rather than attempting to adjudicate between different extant theories, we begin with certain pre-theoretic intuitions about vague terms, and a default position on classical logic. The aim is to see whether (i) a natural story can be told which will explain the vagueness phenomenon and the puzzling nature of soritical arguments, and, in the course of this, to see whether (ii) there arises any compelling pressure to give up the natural stance. We conclude that there is a simple and natural story to be told, and we tell it, and that there is no good reason to abandon our intuitively compelling starting point. The importance of the strategy lies in its dialectical structure. Not all positions on vagueness are on a par. Some are so incredible that even their defenders think of them as positions of last resort, positions to which we must be driven by the power of philosophical argument. We aim to show that there is no pressure to adopt these incredible positions, obviating the need to respond to them directly. If we are right, semantic vagueness is neither surprising, nor threatening. It provides no reason to suppose that the logic of natural languages is not classical or to give up any independently plausible principle of bivalence. Properly understood, it provides us with a satisfying diagnosis of the sorites argumentation. It would be rash to claim to have any completely novel view about a topic so well worked as vagueness. But we believe that the subject, though ancient, still retains its power to inform and challenge us. In particular, we will argue that taking seriously the central phenomenon of predicate vagueness—the “boundarylessness” of vague predicates—on the commonsense assumption that vagueness is semantic, leads ineluctably to the view that no sentences containing vague expressions (henceforth ‘vague sentences’) are truth-evaluable. This runs counter to much of the literature on vagueness, which commonly assumes that, though some applications of vague predicates to objects fail to be truth-evaluable, in clear positive and negative cases vague sentences are unproblematically true or false. It is clarity on this, and related points, that removes the puzzles associated with vagueness, and helps us to a satisfying diagnosis of why the sorites arguments both seem compelling and yet so obviously a bit of trickery. We give a proof that semantically vague predicates neither apply nor fail-to-apply to anything, and that consequently it is a mistake to diagnose sorites arguments, as is commonly done, by attempting to locate in them a false premise. Sorites arguments are not sound, but not unsound either. We offer an explanation of their appeal, and defend our position against a variety of worries that might arise about it. The plan of the paper is as follows. We first introduce an important distinction in terms of which we characterize what has gone wrong with vague predicates. We characterize what we believe to be our natural starting point in thinking about the phenomenon of vagueness, from which only a powerful argument should move us, and then trace out the consequences of accepting this starting point. We consider the charge that among the consequences of semantic vagueness are that we must give up classical logic and the principle of bivalence, which has figured prominently in arguments for epistemicism. We argue there are no such consequences of our view: neither the view that the logic of natural languages is classical, nor any plausible principle of bivalence, need be given up. Next, we offer a diagnosis of what has gone wrong in sorites arguments on the basis of our account. We then present an argument to show that our account must be accepted on pain of embracing (in one way or another) the epistemic view of “vagueness”, i.e., of denying that there are any semantically vague terms at all. Next, we discuss some worries that may arise about the intelligibility of our linguistic practices if our account is correct. We argue none of these worries should force us from our intuitive starting point. Finally, we cast a quick glance at other forms of semantic incompleteness. (shrink)

According to the classical account, propositions are sui generis, abstract, intrinsically-representational entities and our cognitive attitudes, and the token states within us that realize those attitudes, represent as they do in virtue of their propositional objects. In light of a desire to explain how it could be that propositions represent, much of the recent literature on propositions has pressured various aspects of this account. In place of the classical account, revisionists have aimed to understand propositions in terms of more familiar (...) entities such as facts, types of mental or linguistic acts, and even properties. But we think that the metaphysical story about propositions is much simpler than either the classical theorist or the revisionist would have you believe. In what follows, we argue that a proper understanding of the nature of our cognitive relations to propositions shows that the question of whether propositions themselves represent is, at best, a distraction. We will argue that once this distraction is removed, the possibility of a very pleasing, minimalist story of propositions emerges; a story that appeals only to assumptions that are shared by all theorists in the relevant debate.

As a philosopher, psychologist, and physician, the German thinker Hermann Lotze defies classification. Working in the mid-nineteenth-century era of programmatic realism, he critically reviewed and rearranged theories and concepts in books on pathology, physiology, medical psychology, anthropology, history, aesthetics, metaphysics, logic, and religion. Leading anatomists and physiologists reworked his hypotheses about the central and autonomic nervous systems. Dozens of fin-de-siècle philosophical contemporaries emulated him, yet often without acknowledgment, precisely because he had made conjecture and refutation into a method. In spite (...) of Lotze's status as a pivotal figure in nineteenth-century intellectual thought, no complete treatment of his work exists, and certainly no effort to take account of the feminist secondary literature.

Justificationism is the epistemology that enjoins us to choose our beliefs according to this principle: choose all and only those beliefs and at an appropriate degree of confidence that one can justify, either by an intellectual certificate or empirical warrant. My article argues that most forms of justificationism require the truth of doxastic voluntarism, the doctrine that one may choose ones specific beliefs. However, since belief is involuntary, justificationism is severely undermined. Justificationism as stated couldn’t be practised; since believing is (...) not something we can do at will as a basic action. Although devastating to any subjectivist justificationism, it does not undermine our ability to cultivate, through long-term choices, the most rational attitude in the search for truth and the growth of knowledge. A major rival of subjective justiticationism (SJ) is critical rationalism (CR). CR is the doctrine that progress in the growth of knowledge occurs through the unrelenting criticism of competing unjustified conjectural attempts to solve problems. The objective methods and standards involved in CR are unaffected because following (or not) an objective method is something we can do at will. (shrink)

In what way might the new classicism gain support from evolutionary theory? My rough answer is that evolutionary theory can help defend a return to more classical artistic standards and also explain why classical standards are not simply imposed by social conditioning or by powerful elites, but arise naturally from something more fundamental in the human constitution. Classical standards and themes are an expression of our evolutionary history. The mind can be seen as a biological organ or function, produced by (...) evolutionary selection pressure. The most arguable and interesting expression of this point of view is that which says that the human mind is more like a Swiss army knife than a general-purpose computer or sponge for information. Our minds are modular. First propounded by Jerry Fodor, the idea was taken up by evolutionary psychologists and fleshed out with a history. Evolution has given us cognitive modules, partly self-contained mental “machines” that are attuned to solving problems with a narrowly defined domain. Darwinian evolution has shaped our minds in particular ways that fundamentally affect our evaluation of everything we perceive and therefore our appreciation of art. I draw out a surprising implication of combining the modular view with evolution: that our aesthetic standards may, to some extent, be fragmented and not quite as universal as held by the orthodox defence of classical art.

David Ray Griffin does not fully come to terms with the fact that science has already abandoned the narrow materialist view of bits of matter pushing each other around. Even as early as Newton's law of gravitation, and most obviously with quantum physics, science has embraced the view that the world consists of relationships (often described as laws) between different types of processes and states.

Natural resources are infinite. This is possible because humans can create theories whose potential goes beyond the limited imaginative capacity of the inventor. For instance, no number of people can work out all the economic potential of quantum theory. Economic Resources are created by an interaction of Karl Popper's Worlds 1, 2 and 3, the worlds of physics, psychology and the abstract products of the human mind, such as scientific theories. Knowledge such as scientific theories has unfathomable information content, is (...) universally applicable, and infinitely copyable. The point can be made with technological knowledge such as that embodied in the wheel. The theory of the wheel has un- bounded potential to be embodied in unforeseeable new technologies, is useful on the Moon as on Earth, and can be infinitely copied. Unlike a piece of land (using fixed factors), such knowledge shows increasing returns. This helps to explain Julian Simon's observation that "natural" resources are now less scarce than they used to be and why an increasing population can increase resources in the long-run. It was Simon's breakthrough to elaborate on the abstract character of "natural" resources. I further explore this abstract character and thereby explain why natural resources are infinitely expandable. Economic growth and the creation of natural resources depends on the rate of invention. F. Machlup's suggestion (Machlup 1962) that the opportunity for new inventions increases geometrically with the number of inventions at hand is acknowledged for its suggestiveness, but criticised for its conservative position. Frank Tipler's fascinating argument for indefinite economic growth (Tipler 1994), is reinforced by my argument by making a distinction between information in the engineer's sense and the infinite potential "information" in our scientific knowledge based on Popper's notion of information content.

Richard Dawkins tries to establish an analogy between computer viruses and theistic belief systems, analyzing the latter in terms of his concept of the meme. The underlying thrust of Dawkins' argument is to downplay the role of truth and logic in the survival of theories and to emphasize humankind's helpless liability to incurable infection by doctrines that Dawkins regards as absurd. Dawkins supplies a list of "symptoms” of mind-infection. However, on closer investigation these characteristics are found to be either rather (...) weak protection against criticism or quite virtuous. Dawkins relies on a crude justificationism that could just as well be called a mind-virus. Applying Dawkins’ own selection of the general characteristics of a good meme protector and propagator leads to the conclusion that his particular theistic examples would actually impair copyability. -/- Scientific theories are better examples of memes with high longevity, fecundity, and fidelity. A Darwinian analysis of wishful and fearful thinking as useful to hypotheses-testing and goal-seeking organisms undermines Dawkins' attribution of absolute irrational stubbornness to theists. To counterbalance Dawkins' emphasis on the propagation of the absurd, I rehabilitate the Socratic emphasis on the importance of truth and logic in rhetoric, interpreted broadly as the theory of the successful propagation of a message. I use Popper's notion of situational analysis, and an evolutionary perspective to argue that rational standards of a message enhance its copyability. I further apply Popper’s notions of World 3, 2, and 1 to memes; this helps us see the perpetuation of a doctrine as a logical task. (shrink)
