The Peripatetic treatise Peri pneumatos has recently received a great deal of scholarly attention. Some authors, predominantly A. Bos and R. Ferwerda, try to prove that the treatise is a genuine work of Aristotle and all the theories advanced in the text can be ultimately explained by references to this or that Aristotelian doctrine. Quite on the contrary, P. Gregoric, O. Lewis and M. Kuhar are firmly convinced that the treatise contains some physiological ideas introduced after Aristotle and are inclined (...) to support the traditional dating of the treatise to the time after Praxagoras of Cos. Largely in agreement with the latter proposition, in the present study I tentatively place this earliest and unique witness of the discussions on the source of growth and nourishment of the so-called connate pneuma in the context of the Peripatetic tradition of the Early Hellenistic period. The treatise is translated into the Russian for the first time. (shrink)

A fundamental problem in science is how to make logical inferences from scientific data. Mere data does not suffice since additional information is necessary to select a domain of models or hypotheses and thus determine the likelihood of each model or hypothesis. Thomas Bayes’ Theorem relates the data and prior information to posterior probabilities associated with differing models or hypotheses and thus is useful in identifying the roles played by the known data and the assumed prior information when making inferences. (...) Scientists, philosophers, and theologians accumulate knowledge when analyzing different aspects of reality and search for particular hypotheses or models to fit their respective subject matters. Of course, a main goal is then to integrate all kinds of knowledge into an all-encompassing worldview that would describe the whole of reality. A generous description of the whole of reality would span, in the order of complexity, from the purely physical to the supernatural. These two extreme aspects of reality are bridged by a nonphysical realm, which would include elements of life, man, consciousness, rationality, mental and mathematical abstractions, etc. An urgent problem in the theory of knowledge is what science is and what it is not. Albert Einstein’s notion of science in terms of sense perception is refined by defining operationally the data that makes up the subject matter of science. It is shown, for instance, that theological considerations included in the prior information assumed by Isaac Newton is irrelevant in relating the data logically to the model or hypothesis. In addition, the concepts of naturalism, intelligent design, and evolutionary theory are critically analyzed. Finally, Eugene P. Wigner’s suggestions concerning the nature of human consciousness, life, and the success of mathematics in the natural sciences is considered in the context of the creative power endowed in humans by God.

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)

THERE IS WIDESPREAD AGREEMENT among historians that the writings of Robert Boyle (1697-1691) constitute a valuable archive for understanding the concerns of seventeenth-century British natural philosophers. His writings have often been seen as representing, in one fashion or another, all of the leading intellectual currents of his day. ~ There is somewhat less consensus, however, on the proper historiographic method for interpreting these writings, as well as on the specific details of the beliefs expressed in them. Studies seeking to explicate (...) Boyle's thought have been, roughly speaking, of two general sorts. On the one hand there are those studies of a broadly "intellectualist" orientation which situate his natural philosophy within the intellectual context provided by metaphysics, religion, and early modern science. In this connection his corpuscularianism has been shown to be motivated by specific epistemological, theological, as well as empirical concerns. One of the central aims of such studies has been to show that apparently discordant elements in his scientific thought are rendered coherent by referring them to such "non-scientific" commitments. Among studies of this sort might be mentioned the works of John Hedley Brooke, E. A. Burtt, Gary B. Deason, J. E. McGuire, R. Hooykaas, Robert H. Kargon, Eugene M. Klaaren, P. M. Rattansi, and Richard S. Westfall. (shrink)

Syntax has to do with rules that constrain how words can combine to make acceptable sentences. Semantics (Frege and Russell) concerns the meaning of words and sentences, and pragmatics (Austin and Grice) has to do with the context bound use of meaning. We can hence distinguish between three competing principles of translation: S—translation preserves the syntax of an original text (ST) in the translation (TT); M—translation preserves the meaning of an ST in a TT; and P—translation preserves the pragmatics of (...) an ST in a TT. A prominent form of P is functionalism defended by linguists and translation theorists (J.R. Firth, Eugene Nida, Susan Bassnett and many others) and historically was defended by philosophers (Russell, Ogden and Richard) but abandoned by philosophers and criticized by Wittgenstein. If we adopt M, then a TT will always say exactly what the ST says, and hence all subsequent TTs, even alternative ones produced via M, will be consistent with each other. But if we adopt P, in contrast, we have no reason to believe that the TTs will say what the ST does, and moreover they can contradict each other. If such contradictory translations are produced on the basis of the totality of empirical evidence, it results in what Quine called the indeterminacy of translation. Yet, P is not easy to reject. In many cases, translation in accordance with M where the meaning to be preserved is linguistic results in TTs that are failures. In contrast to a language focused approach to semantics, I close by following a lead in the translation theory literature of identifying text-types (genres) as a tool for identifying translatable content in an ST. To individuate text-types I identify them with disciplines, as elucidated by the 2nd century Patañjali’s Yoga Sūtra. This allows for the definition of textual meaning as the discipline relative pragmatics of an ST and further for translation to proceed by way of M, while taking the intuitions that motivate P seriously. Translations that preserve textual meaning will not only have the same meaning as each other but will be pragmatically felicitous. (shrink)

MANEJO NA AVICULTURA: POSTURA, ILUMINAÇÃO E INCUBAÇÃO DOS OVOS -/- MANAGEMENT IN POULTRY: POSTURE, ILUMINATION AND INCUBATION OF THE EGGS -/- 1. INTRODUÇÃO A produção de ovos no Brasil está próxima de 45 bilhões de unidades por ano, mantendo um desenvolvimento constante em todos os seus aspectos: genética, instalações, patologia, alimentação, etc. Ao longo do presente trabalho, pretende-se estabelecer os conceitos que estão ligados à produção de ovos, distribuição de ovoprodutos e refletir as ideias básicas sobre os programas de iluminação (...) nas galinhas. Num segundo bloco serão analisados aspectos relacionados com a incubação dos ovos, como a higiene e o manejo, o tratamento do ovo e, por último, a caracterização dos fatores envolvidos no processo da incubação. 2. PREPARAÇÃO/POSTURA DOS OVOS A galinha começa a ovulação normalmente a partir das 20-22 semanas de vida, se bem que mediante práticas de manejo (alimentação, programas de luz, etc.) pode-se adiantar ou atrasar o momento do início das primeiras ovulações. A genética tem, logicamente, um papel importante na idade em que se alcança a puberdade das aves. Mencionamos ritmos de postura por ser a oviposição facilmente verificável, já que nem toda ovulação é seguida de oviposição, como nos casos de queda da gema na cavidade intraperitoneal. Aos primeiros sinais de postura de ovos em frangas jovens, frequentemente observam-se certas irregularidades como: a) Postura irregular: longos intervalos entre dois ovos ou mais de um ovo por dia (geralmente são anormais). b) Ovos com casca mole («soft shelled eggs»), sem a adequada classificação de cálcio. c) Ovos com duas gemas. Talvez estes fenômenos sejam provenientes de uma excessiva estimulação do ovário e disfunções do oviduto. Em suma, tudo isto pode ser consequência da falta de sincronização dos complexos mecanismos que regulam o processo. Uma vez regularizada a postura dos ovos, verifica-se que a galinha coloca um número de ovos sucessivos, seguido de uma pausa ou descanso na postura (choco) de um ou vários dias. O número de ovos que põe seguidos é chamado de sequência ou série de postura. Normalmente, essa “pausa” acontece após uma sequência de quatro a seis ovos postos. A sequência de postura de uma galinha pode ser regular, ou seja, que se repete sucessivamente o número de ovos postos de forma contínua, ou irregular quando essa sequência não obedece ao padrão normal, sendo ela derivada. O mesmo aconteceria com os dias de descanso. Como exemplo podemos encontrar: XXXX - XXXX - série e repouso regular XXX — XX — série e descanso irregular O espaço de tempo entre dois ovos de cada série é um caráter individual. Verificações de Menher (1969) indicam que o intervalo médio entre dois ovos sucessivos de uma série depende da duração desta. Em grandes séries diminui o tempo entre dois ovos sucessivos. À medida que a idade da galinha aumenta, as séries diminuem. Também observa-se que o tempo transcorrido entre dois ovos sucessivos é menor na metade da série e máximo no final da série. Uma galinha com uma série regular do tipo: XXXX - XXXX durante um período de tempo concreto permite-nos estabelecer que tem uma intensidade de postura de 80%. A intensidade de postura é definida como a porcentagem de ovos de um efetivo de galinhas num determinado período de tempo. A evolução da porcentagem de postura ao longo da vida produtiva do rebanho nos dá a curva de postura com três fases: crescimento, constância retilínea e decrescente. Define-se como período de postura o intervalo de tempo entre o início da postura da galinha (20-22 semanas) e o fim da mesma. A duração deste período pode ser variável (entre 12 e 20 meses), dependendo de vários fatores. Se observarmos a hora de oviposição dos diferentes ovos de uma série de galinhas, verificaríamos que a mesma se atrasa dia após dia. Este é um fato lógico, tendo em conta que a formação do ovo é superior a 24 horas. Também se comprova que em nenhum caso há oviposições nos períodos de escuridão quando se mantêm programas clássicos de iluminação (porém, é frequente comprovar que uma porcentagem de ovos podem ser postos durante o período de escuridão). O controle dos mecanismos que regulam os ritmos de ovulação e que definirão as séries é muito complexo, então tento fazer um pequeno resumo. Uma vez produzida a ovulação, a presença de um ovo em formação colocaria em funcionamento um sistema «Feedback» negativo da seguinte forma: gema → gera estímulos nervosos → hipotálamo → suprime RH → sem estimulação da hipófise → bloqueio de uma nova ovulação Esta ideia não é tão simples e se desconhecem em profundidade os mecanismos que a regulam. Observe uma figura que detalha melhor a formação do ovo e a passagem pelos respectivos compartimentos reprodutivos da galinha. 3. DISTRIBUIÇÃO DAS OVIPOSIÇÕES Com programas de iluminação clássicos (17L:7N) já assinalámos que a oviposição na galinha realiza-se no período de luz, e que diariamente o momento de tal oviposição irá sendo regredido (atrasado). No entanto, existe algumas horas onde a frequência máxima de postura é concentrada, que normalmente coincide com as 2-4 horas após a iluminação. Se, experimentalmente, fornecermos 24 horas de luz às galinhas, a postura ocorre durante todo o período, seja de forma aleatória ou através os estímulos a determinados pontos de referência de fatores externos periódicos: ruídos, entradas, fala de pessoas, etc., então podemos estabelecer que existe um certo sincronismo. Quando os programas de iluminação que se seguem nas granjas de galinhas poedeiras não se ajustam às 24 horas ou que seguem programas fraccionados, a resposta é diversificada e deixamos sua avaliação até não conhecer os distintos programas especiais de iluminação. 4. BASES DA ILUMINAÇÃO PARA GALINHAS POEDEIRAS O estabelecimento de programas de iluminação começa na fase de recria da franga e dada a influência que a luz exerce sobre o desenvolvimento da maturidade sexual, os programas que se instauram terão um impacto sobre o futuro produtivo das frangas. As considerações que devem ser levadas em conta no estabelecimento dos programas de iluminação são as seguintes: a) Os programas devem ser considerados como uma "globalidade" durante toda a vida da galinha. A instauração de programas de iluminação das galinhas poedeiras deve estar em conformidade com o programa seguido durante a fase de recria. b) Os aumentos no fotoperíodo durante a fase de recria implica um adiantamento no aparecimento da maturidade sexual da galinha. Este efeito deve ser considerado prejudicial, uma vez que esta postura precoce é acompanhada de tamanhos inferiores de ovos (cuja avaliação no mercado é reduzida). Este avanço no início da postura pode levar a uma falta de harmonia entre puberdade e o desenvolvimento corporal (aponta-se para uma maior incidência de prolapsos). Também indica-se que uma maturidade sexual precoce pode ser acompanhada de irregularidades na postura, pior qualidade da casca e até a um maior índice de mortalidade. c) A redução do fotoperíodo durante a recria permite atrasar o momento do início da postura e a produção de ovos é de uma maior dimensão inicial, o que compensa a ligeira diminuição do número de ovos na sua vida produtiva. d) Estabelecido um programa e posto em prática não pode alterar-se o mesmo. e) Nunca diminuir o fotoperíodo na fase de produção de ovos. f) As alterações do fotoperíodo (aumentos ou diminuições) não passam de um conceito de sensibilidade ao fato do que da magnitude dessas alterações. g) As alterações no fotoperíodo afetam inicialmente o consumo de ração das frangas, mas estas adaptam-se rapidamente aos seus níveis de ingestão e suprimento de exigências ao novo fotoperíodo. h) Ações qualitativas (limitação de um nutriente) ou quantitativas na ração fornecida podem permitir, em si mesmas, o atraso da maturidade sexual das frangas, embora não se apliquem normalmente para este fim. O controle quantitativo do gênero alimentício obedece a estratégias destinadas a obter o peso ideal para uma determinada idade de acordo com as normas fornecidas pelo fornecedor das diferentes estirpes comerciais. i) Na decisão final, ao se definir um programa deve-se ter presente: Tipo de alojamento: — Galpão com ambiente controlado. — Galpão convencionais com janelas. Neste último caso a época de nascimento das frangas será um fator relevante a ser levado em consideração. Como aspectos a destacar poderíamos citar: — Durante os primeiros dias de vida da galinha convém fornecer-lhe luz durante as 24 horas, a fim de facilitar a adaptação ao seu novo habitat (localização de comedouros e bebedouros, etc.). — Durante a fase de recria devem ser evitadas falhas que estabeleçam períodos fotocrescentes, já que alterarão a resposta produtiva posterior de tais frangas (especialmente se altera-se na última fase do período decrescente). 4.1 Programas práticos de iluminação na recria Ao longo do trabalho consideraremos sempre uma recria de 20 semanas, embora este dado possa ser variável de acordo com: a) Melhoria genética das estirpes atuais, as quais tendem a ser mais precoces. b) Tentativa de uma maior produção de ovos. No caso de reprodutoras semipesadas, a duração do período de recria pode ser de 21-22 semanas. 4.1.1 Galpões convencionais com janelas Neste tipo de galpão a iluminação externa incide no interior do navio e devem ser estabelecidos programas para combater o aumento de luz natural que se apresenta de janeiro a junho. 1. Programa de fotoperíodo decrescente Para realizar este tipo de programa pode-se seguir esta rotina: a) Verificar na tabela as horas de luz natural (x) que vão dispor-se quando as frangas cumprirem as 20 semanas de vida. b) Aumentar em 6 horas o valor observado na tabela (x + 6 horas) e fornecê-las aos 4 ou 5 dias de vida. c) Diminuir semanalmente a iluminação artificial, de tal forma que quando chegarem às 20 semanas de vida, a luz fornecida coincida com a luz solar. Exemplo prático: frangas nascidas em 8 de janeiro: a) Observa-se em tabela que cumprirão as 20 semanas em 28 de maio, tendo um comprimento do dia de 14 horas e 45 minutos. b) aumentamos em 6 horas e fornecemos 20 horas e 45 minutos a partir do quarto dia. c) Diminuímos semanalmente 360 minutos/20 semanas = 18 minutos e quando cumprirem as 20 semanas de vida, o fotoperíodo de que dispõem (14 horas e 45 minutos) coincide com o comprimento do dia. 2. Programa de fotoperíodo constante a) Para levar a cabo este tipo de programa deve-se verificar na tabela o comprimento do dia mais longo durante as 20 semanas que dura a recria. b) Proporcionar essas horas de luz a partir dos primeiros 3-4 dias durante as 20 semanas. O uso de programas de luz constante em galpões convencionais com janelas não é muito frequente, apesar da certa poupança energética que acarreta. 4.1.2 Galpões com ambiente controlado Neste tipo de galpão considera-se que a luz solar não exerce nenhuma ação no interior do mesmo. No entanto, é necessário atentar-se para que o conceito de galpão totalmente escuro seja levado até às suas últimas consequências, evitando que por sistemas de ventilação, etc., possam existir fugas de luz que alterariam os programas de iluminação propostos. Nos galpões com ambiente controlado seguem-se dois tipos de programas: 1. Programa decrescente-constante Durante as primeiras semanas vai-se diminuindo o fotoperíodo paulatinamente (1 ou 2 horas) até chegar a 8 ou 10 horas, que ficariam constantes até as 20 semanas de idade. Uma variável deste programa consiste em ir diminuindo lentamente as horas de luz e por volta da 12ª semana fazer uma diminuição brusca, deixando um fotoperíodo de 7-8 horas, que se perduraria até às 20 semanas de vida. 2. Programa constante Consiste em proporcionar de 7 a 10 horas de luz constante durante toda a fase de recria (com exceção dos primeiros dias, os quais se consideram de adaptação). Na hora de estabelecer a intensidade luminosa nesta fase de recria nos encontramos com intervalos muito amplos. Diferentes fornecedores de frangas recomendam de 20 a 40 lux durante os primeiros dias e ir diminuindo de tal forma que ao primeiro mês de vida estejam a 10-20 lux. A partir da 5 semana e até 3-4 meses vem sendo recomendada 5-10 lux para que possa, assim, aumentar a intensidade a partir dessa data para níveis de 10-30 lux. 4.2 Programas clássicos de iluminação na fase de postura Uma vez que as frangas tenham atingido as 20 semanas de idade, é preciso estabelecer os programas de iluminação para o período de postura. É necessário considerar, como se fazia no período de recria, o tipo de galpão em que vão residir durante todo o período de postura, bem como o programa seguido na fase de recria. Recordando novamente que ao longo do período de postura nunca se deve diminuir a duração do fotoperíodo, passamos a definir os programas de iluminação mais usuais em função do tipo de galpão: 4.2.1 Galpões convencionais com janelas 1. Programa crescente Consiste em ir incrementando o fotoperíodo a partir da 20ª semana. Podem existir várias opções: a) Aumento do fotoperíodo semanal de forma constante até atingir as 16-17 horas de iluminação. b) Aumento brusco do fotoperíodo às 21 e 23 semanas até atingir as 15,5 horas de iluminação, que ficariam fixas em toda a fase de postura. Esta é uma recomendação clássica de algumas casas comerciais. Em galpões convencionais com janelas, os programas de iluminação constante não costumam ser utilizados. 4.2.2 Galpões de ambiente controlado Neste tipo de galpão deve ser instaurado um programa de fotoperíodo crescente. Às 20 semanas e em função do fotoperíodo que seguiram na fase de recria o incremento pode ser brusco (caso de frangas recriadas com 8-10 horas de iluminação, pode-se passar a 12-13 horas) e seguir posteriormente com incrementos de 20-30 minutos até atingir as 16-17 horas de iluminação. A intensidade da luz durante a fase de produção de ovos é unânime em considerar os valores de 10-15 lux como os mais adequados, desde que exista homogeneidade na sua distribuição. Atualmente, as recomendações das diferentes casas comerciais de estirpes de poedeiras são mais elevadas: na ordem de 20 a 30 lux. Níveis muito superiores não têm efeito sobre a produção de ovos e podem desencadear problemas de arranque de penas quando a intensidade é excessiva. 4.3 Outros programas de iluminação Em instalações de ambiente controlado os custos energéticos representam um capítulo importante dentro dos custos de uma exploração avícola. A fim de economizar energia, uma série de programas de iluminação vem sendo ensaiada, especialmente para a fase de postura, que poderíamos englobar em dois grupos: a) intermitentes ou fracionados. b) Não ajustados a 24 horas. 5. HIGIENE E MANEJO DA INCUBAÇÃO A higiene de todo o processo de incubação deve servir para estabelecer uma primeira medida de ruptura da cadeia de infecção. Há uma série de doenças como Marek, pulorose, encefalomielite aviária, micoplasmose, etc., que estão associadas ao processo de incubação. A higiene de todo o processo deve corresponder inicialmente ao controle na exploração, de tal forma que os reprodutores devem estar, do ponto de vista sanitário, em perfeitas condições e estendê-las ao manejo mecânico do ovo, regulação de entradas e saídas e igualmente a todas as instalações. Antes de continuar com o manejo do ovo para a incubadora, convém recordar alguns aspectos do desenvolvimento embrionário que ocorre dentro da própria galinha: o ovo é fertilizado na parte distal do infundíbulo cerca de 15 minutos após a ovulação, e quando se encontra no istmo (às 5 horas) já se produzem as primeiras divisões celulares. Às 9 horas da ovulação, o blastodermo cresce até um estágio de 256 células e antes da oviposição a formação do tubo digestivo (gastrulação) já está completada no embrião (PARKHURST e MOUNTNEY, 2012). As divisões celulares continuam após a oviposição, desde que as temperaturas estejam acima de 26,8ºC (zero fisiológico). 6. MANEJO DO OVO PARA A INCUBAÇÃO A colheita dos ovos nas explorações de reprodução deve ser efetuada com uma certa periodicidade (três a cinco vezes por dia), a fim de evitar problemas de roturas e de ovos sujos. Não devemos esquecer que a colocação em um mesmo ninho de vários ovos originam modificações nas temperaturas dos mesmos (superiores a zero fisiológico), que poderiam estar associadas a um reinício das divisões celulares no embrião. Uma vez recolhidos, os ovos devem ser instalados num armazém que permita manter uma temperatura de 15-18ºC (nunca inferior a 10ºC) e uma umidade de 70-75% para evitar uma perda de peso excessiva. A temperatura de armazenagem dos ovos para incubação pode variar em função do tempo em que permanecerão armazenados, pelo que é conveniente programar temperaturas mais baixas para um período de armazenagem mais longo. Alguns autores estabelecem que os ovos que permanecerem 3 dias na incubadora podem ser programados com temperaturas de 15ºC, enquanto que os que se armazenam por mais de 9 dias a temperatura recomendada é de 12ºC. Os ovos com problemas de casca, tais como calcificações defeituosas, quebra ou fissura, ovos com formas anormais e ovos com casca lisa e bem formada, devem ser eliminados na própria instalação. A uniformidade do tamanho dos ovos é um aspecto a destacar e o intervalo de peso mais adequado é de 55-65 g. Os ovos de maior tamanho sempre apresentam níveis mais elevados de problemas de casca e o período de incubação do mesmo é superior (até mais de 12 horas), por isso não é aconselhável introduzi-los na incubadora, assim como os ovos pequenos e os de gema dupla. Os trabalhos de Ron Jones (1978) evidenciam a importância do tamanho dos ovos ao considerar que as perdas de peso por evaporação são mais rápidas nos ovos de menor peso, e inclusive assinala que os ovos de casca branca são mais porosos, sugerindo sua incubação separada em função do tamanho. A desinfecção dos ovos (fumigação) com uma solução de formalina é prática corrente (45 ml de uma solução de formalina a 40% e 30 g de permanganato de potássio por metro cúbico de espaço ou 10 g/m3 de paraformaldeído aquecido num fumigador eléctrico), segundo as recomendações do Guia Cobb (1991). Um excesso de gás formaldeído pode ser neutralizado através da introdução de amoníaco líquido concentrado, 20 ml/m3. Pode também utilizar-se uma solução de cloro (500 ppm) a 43ºC durante 2 minutos, bem como produtos com amônio quaternário. Quando o tempo de armazenamento dos ovos para incubação é inferior a uma semana, a posição dos ovos para incubação dificilmente influencia a incubabilidade posterior. No entanto, quando o tempo de armazenamento excede 2 semanas, a incubabilidade dos ovos melhora se eles são virados diariamente. Romanoff, em 1960, estabeleceu os valores de incubabilidade dos ovos em função do tempo de armazenagem, verificando-se que, à medida que o período de tempo entre a postura dos ovos e a colocação na incubadora aumenta, os resultados de incubação diminuem, como pode ser observado na tabela 1: Tabela 1: Valores de incubalidade dos ovos em função do tempo de armazenamento -/- Período de armazenamento (dias) Incubalidade (%) 14 80 21 70 28 30 32 < 10 Fonte: ROMANOFF, 1960. Para evitar mudanças bruscas de temperatura (da sala de armazenamento da incubadora), que podem causar transpirações nos ovos, recomenda-se um aumento gradual da temperatura (12 a 18 horas antes de serem introduzidos na incubadora). Os ovos fecundados que são submetidos a longos percursos até chegarem ao incubatório devem ser mantidos no armazém durante 1 ou 2 dias antes de serem colocados nas incubadoras, melhorando assim os resultados de incubação. Através dos poros há uma troca de gases durante o armazenamento. O dióxido de carbono difunde-se no exterior e a sua concentração no ovo diminui rapidamente nas primeiras 12 horas após a postura. Se juntarmos as perdas de vapor de água, descobriremos que o armazenamento tem um impacto negativo nos resultados finais do processo de incubação. Experimentalmente, o tempo de armazenagem dos ovos fertilizados pode ser prolongado através da embalagem hermética em atmosfera de nitrogênio ou de anidrido carbônico, incluindo o revestimento de óleos. Alguns incubatórios testam o revestimento dos ovos com materiais plásticos para evitar tais perdas, todavia não é muito indicado, uma vez que lacra a passagem do oxigênio exterior para o embrião interior. No caso de nos depararmos com ovos sujos, e apesar dos condicionantes sanitários que vão associados, pode-se recorrer à sua limpeza e lavá-lo com água e algum desinfetante. Se a limpeza for excessiva, deve considerar-se a alteração que pode ter sofrido a cutícula da casca, pelo que não se recomenda a raspagem manual ou mecânica da mesma. De acordo com o estabelecido pelo Guia Cobb (1991), os efeitos mais importantes do armazenamento dos ovos são: a) O armazenamento prolonga o tempo de incubação e, em média, um dia de armazenamento prolonga o tempo de incubação por 1 hora. b) A armazenagem reduz a incubabilidade dos ovos. Este efeito, descrito acima, é quantificado de forma que a partir do quinto dia de armazenamento, cada dia de armazenamento adicional representa perdas de 0,5 a 1% na incubabilidade. c) O peso dos ovos pode diminuir quando o armazenamento dos ovos é de 14 dias ou mais. 6.1 Carregamento dos ovos na incubadora Embora ainda existam incubatórios que introduzem os ovos diretamente do armazém para a incubadora, recomenda-se um pré-aquecimento suave dos ovos até atingir temperaturas próximas dos 23ºC em 6 horas, independentemente da temperatura de partida. Duas horas antes de serem colocados na incubadora, a temperatura considerada ideal é de 28ºC. 6.2 Tempo de incubação Como já foi explicado acima, o tempo necessário para a incubação dos ovos de galinha deriva de uma função de vários fatores, de modo que os 21 dias e 4 horas (508 horas) que são definidos como tempo de referência podem ser ligeiramente modificados. 7. FATORES ENVOLVIDOS NO PROCESSO DE INCUBAÇÃO Os resultados obtidos por diferentes incubatórios variam consideravelmente de um para outros. As causas destas variações podem estar relacionadas ao manejo dos reprodutores, fertilidade dos ovos e na própria incubação. Cada empresa que dispõe de incubatórios desenvolve seu próprio método de operação no processo de incubação e seus padrões de qualidade exigidos nos pintainhos são geralmente variáveis. Vários fatores que desempenham um papel importante no processo de incubação já foram descritos ao comentar o manejo do ovo para incubação: uniformidade de pesos, qualidade de casca, armazenamento, etc., por isso é necessário assinalar os parâmetros a controlar na incubadora e no nascedouro. Em suma, podem ser estabelecidas as seguintes condições: Parâmetros Incubadora Nascedouro Temperatura (ºC) 37,5 – 37,7 37,1 Umidade relativa (%) 55 – 60 < 75 Ventilação (m3/minuto/1000 ovos) 0,14 0,23 – 0,28 Nível de CO2 0,3 – 0,4 0,5 – 0,6 Nível de O2 21 21 Número de viagens/dia < 4 – 6 — Tabela 2: Condições aceitas para a incubação dos ovos e nascimento dos pintainhos. 7.1 Manejo com os pintainhos de 1 dia – do incubatório para os galpões Numa sala convenientemente climatizada, 22-25 ºC e 70-80% de umidade, procedem-se as seguintes operações: a) Triagem dos pintainhos - Eliminando os que apresentem anomalias ou tenham pouca viabilidade/vitalidade, problemas nos membros, bico, olhos, se apresentam-se fracos, etc. b) Sexagem dos pintainhos - A separação dos sexos tem um interesse relativo no caso dos criadouros e criadores, mas é uma operação obrigatória quando o que interessa é produzir galinhas de postura ou reprodutores. Para o processo de separação por sexo podem ser utilizados dois sistemas: — Exame da cloaca, seguindo o método de Masui e Hashimoto, no qual é preciso evaginar a cloaca, mediante pressão, e através de uma luz direta observar as protuberâncias que correspondem a cada sexo. A aplicação desta técnica requer um elevado grau de especialização e os erros daí resultantes são insignificantes. Como regra a seguir, quando se aplica esta técnica, é que sua realização deve estar o mais próximo possível ao momento do nascimento. — Mediante o exame de caracteres ligados ao sexo, os caracteres usados para a determinação do sexo nas aves são vários: cores da plumagem (prateados frente a dourados: lisos frente a barrados), mas o mais empregado na atualidade faz referência à comparação dos comprimentos das penas primárias frente às de cobertura (quando as penas primárias são mais longas que as de cobertura, é uma fêmea). Esta técnica também é realizada dentro de poucas horas de nascimento. c) Vacinação dos pintainhos - Durante as primeiras horas de vida, as aves são normalmente alimentadas por via oral (spray) ou por injeção (com vacina manual ou automática). Vacina-se, também, contra várias doenças no primeiro dia de vida dos pintainhos, como a Marek, Gumboro e Bouba Aviária. d) Embalagem - Desenvolvidas as anteriores operações e já dentro da zona de expedição, realiza-se a última triagem e classificação (no caso dos reprodutores e das frangas, o processo pode ter conotações comerciais e podem apresentar-se no mercado várias classes em função da qualidade do produto, que, neste caso, é normalmente o peso), para posteriormente, contar e introduzi-las nas embalagens correspondentes, que podem ser retornáveis ou não. Nas embalagens normalmente introduz-se uma centena de aves (2 por 100) sem custo como regra de compensação às baixas iniciais. Em todas estas operações, o controle da temperatura e da humidade deve ser rigoroso, tal como descrito acima. e) Transporte - Os veículos de transporte devem estar equipados com sistemas auxiliares de calor e arrefecimento que permitam garantir condições estabelecidas, independentemente da situação atmosférica externa. A temperatura do ar fornecido no transporte deve ser de 28ºC quando as frangas estão em embalagens de plástico, enquanto que se forem de papelão a temperatura requerida pode ser bastante inferior (20ºC), segundo o Guia Cobb (1991). A distribuição da carga no transporte (para que a distribuição térmica seja homogénea), o controle contínuo das condições ambientais e os cuidados na condução e na descarga da mercadoria são os últimos aspectos importantes a assinalar. 8. RESUMO E PRIMEIRAS CONCLUSÕES No presente trabalho, tentou-se expor de forma sucinta os aspectos relacionados com a postura dos ovos: irregularidades no início da postura, sequência de postura, intensidade de postura, curva de postura, período de postura e distribuição de oviposições. O controle da iluminação, com seus diferentes programas, tanto em recria como em postura, é objeto de especial desenvolvimento. Uma terceira parte trata da questão da incubação artificial, começando pela higiene e manejo da incubação. É feita especial referência ao manejo dos ovos a serem incubados, e se resume os fatores que controlam o processo de incubação. -/- Emanuel Isaque Cordeiro da Silva – Departamento de Zootecnia da UFRPE.

Albert Einstein once made the following remark about "the world of our sense experiences": "the fact that it is comprehensible is a miracle." (1936, p. 351) A few decades later, another physicist, Eugene Wigner, wondered about the unreasonable effectiveness of mathematics in the natural sciences, concluding his classic article thus: "the miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve" (1960, p. (...) 14). At least three factors are involved in Einstein's and Wigner's miracles: the physical world, mathematics, and human cognition. One way to relate these factors is to ask how the universe could possibly be structured in such a way that mathematics would be applicable to it, and we would be able to understand that application. This is roughly Wigner's question. Alternatively, the way of the mathematical naturalist is to argue that we abstract certain properties from the world, perhaps using our bodies and physical tools, thereby articulating basic mathematical concepts, which we continue building into the complex formal structures of mathematics. John Stuart Mill, Penelope Maddy, and Rafael Nuñez teach this strategy of cognitive abstraction, in very different manners. But what if the very concepts and basic principles of mathematics were built into our cognitive structure itself? Given such a cognitive a priori mathematical endowment, would the miracles of the link between world and cognition (Einstein) and mathematics and world (Wigner) not vanish, or at least significantly diminish? This is the stance of Stanislas Deheane and Elizabeth Brannon's 2011 anthology, following a venerable rationalist tradition including Plato and Immanuel Kant. (shrink)

When a technology is seen as the right solution to a recognized problem, the development of alternative technologies comes under threat. To secure much-needed resources, proponents of alternative technologies must, in these conditions, restart societal discussion on the status quo, a process at once technological and discursive known as ‘path creation’. In this article, we investigate discussion-restarting strategies employed by supporters of emerging technologies in the field of solar fuels, particularly the advocates of a technology referred to as ‘artificial photosynthesis’. (...) For illustrative purposes we explore four such strategies: revisiting weak spots, resizing the problem, redefining the game, and renegotiating labels. We conclude with a methodological reflection on the empirical study of discursive strategies in a socio-technical system. We further suggest a more systematic application of discourse-analytical and argumentation-theoretical insights that can complement current scholarship on path dependence and path creation. (shrink)

"Our literature is replete with complaints about the chaotic state of the systematics of psychoses and every psychiatrist knows that it is impossible to come to any common understanding on the basis of the old diagnostic labels. ... Thus, not even the masters of science can make themselves understood on the basis of the old concepts and with many patients the number of diagnoses made equals the number of institutions they have been too. ... Errors are the greatest obstacles to (...) the progress of science; to correct such errors is of more practical value than to achieve new knowledge. We have here eliminated chaos of terms behind which useful concepts of disease were mistakenly sought; we have eliminated a veritable forest of boundary posts, not one of which indicated any natural line of demarcation. ... By the term „dementia praecox“ or „schizophrenia“ we designate a group of psychoses whose course is at times chronic, at times marked by intermittent attacks, and which can stop or retrograde at any stage, but does not permit a full restitutio ad integrum. The disease is characterized by a specific type of alteration of thinking, feeling, and relation to the external world which appears nowhere else in this particular fashion." Eugen Bleuler.

Future-bias is the preference, all else being equal, for positive states of affairs to be located in the future not the past, and for negative states of affairs to be located in the past not the future. Three explanations for future-bias have been posited: the temporal metaphysics explanation, the practical irrelevance explanation, and the three mechanisms explanation. Understanding what explains future-bias is important not only for better understanding the phenomenon itself, but also because many philosophers think that which explanation is (...) the correct one has implications for our evaluation of the normative status of future-bias. In this paper we focus on the connection between future-bias and the temporal value asymmetry. The latter refers to the fact that people tend to assign more value to a state of affairs when it is located in the future, as opposed to being equidistant in the past. All three candidate explanations offered for future-bias proceed by explaining the temporal value asymmetry, and then supposing that future-bias is simply a manifestation of that asymmetry. Recently, however, it has been argued that the conditions under which people display the temporal value asymmetry and future-bias are different, and that this is reason to doubt that the latter is a manifestation of the former. In this paper we empirically test one response to this argument against the manifestation thesis—the simulation response—according to which once we control for the degree to which people can simulate the object of their preference, we find that people display future-bias and the temporal value asymmetry in the same conditions. We find no evidence in favour of the simulation response. Moreover, our results support some previous research that suggests that the temporal value asymmetry is less robust than previously thought, and this in itself casts doubt on the idea that future bias is just a manifestation of this asymmetry.

This paper empirically raises and examines the question of ‘conceptual control’: To what extent are competent thinkers able to reason properly with new senses of words? This question is crucial for conceptual engineering. This prominently discussed philosophical project seeks to improve our representational devices to help us reason better. It frequently involves giving new senses to familiar words, through normative explanations. Such efforts enhance, rather than reduce, our ability to reason properly, only if competent language users are able to abide (...) by the relevant explanations, in language comprehension and verbal reasoning. This paper examines to what extent we have such ‘conceptual control’ in reasoning with new senses. The paper draws on psycholinguistic findings about polysemy processing to render this question empirically tractable and builds on recent findings from experimental philosophy to address it. The paper identifies a philosophically important gap in thinkers’ control over the key process of stereotypical enrichment and discusses how conceptual engineers can use empirical methods to work around this gap in conceptual control. The paper thus empirically demonstrates the urgency of the question of conceptual control and explains how experimental philosophy can empirically address the question, to render conceptual engineering feasible as an ameliorative enterprise.

Traditional approaches to conflict are oriented towards establishing consensus, either in the form of a resolution of the conflict or in the form of an ‘agree-to-disagree’ standstill between the stakeholders. In this paper, we criticize these traditional approaches, each for specific reasons, and we propose and develop the agonistic approach to conflict. Based on Chantal Mouffe’s agonistic democratic theory, the agonistic approach to conflict is more welcoming of dissensus, replacing discussion stoppers with discussion starters and replacing standstills with contestation. We (...) illustrate such replacements and develop this approach, we analyse technological conflicts in a concrete R&D setting: the global hydrogen economy. From this context, we focus on the conflict between the proponents of blue hydrogen and those of green hydrogen. We conclude by highlighting the advantage of the agonistic approach but also drawing attention to its own specific risk, namely, antagonism. (shrink)

In philosophical thought experiments, as in ordinary discourse, our understanding of verbal case descriptions is enriched by automatic comprehension inferences. Such inferences have us routinely infer what else is also true of the cases described. We consider how such routine inferences from polysemous words can generate zombie intuitions: intuitions that are ‘killed’ (defeated) by contextual information but kept cognitively alive by the psycholinguistic phenomenon of linguistic salience bias. Extending ‘evidentiary’ experimental philosophy, this paper examines whether the ‘zombie argument’ against materialism (...) is built on zombie intuitions. We examine the hypothesis that contextually defeated stereotypical inferences from the noun ‘zombie’ influence intuitions about ‘philosophical zombies’. We document framing effects (‘zombie’ vs ‘duplicate’) predicted by the hypothesis. Findings undermine intuitions about the conceivability of ‘philosophical zombies’ and address the philosophical ‘hard problem of consciousness’. Findings support a deflationary response: The impression that principled obstacles prevent scientific explanation of how physical processes give rise to conscious experience is generated by philosophical arguments that rely on epistemically deficient intuitions.

Several important philosophical problems (including the problems of perception, free will, and scepticism) arise from antinomies that are developed through philosophical paradoxes. The critical strand of ordinary language philosophy (OLP), as practiced by J.L. Austin, provides an approach to such ‘antinomic problems’ that proceeds from an examination of ‘ordinary language’ (how people ordinarily talk about the phenomenon of interest) and ‘common sense’ (what they commonly think about it), and deploys findings to show that the problems at issue are artefacts of (...) fallacious reasoning. The approach is capable, and in need of, empirical development. Proceeding from a case-study on Austin’s paradigmatic treatment of the problem of perception, this paper identifies the key empirical assumptions informing the approach, assesses them in the light of empirical findings about default inferences, contextualisation failures, and belief fragmentation, and explores how these findings can be deployed to address the problem of perception. This facilitates a novel resolution of the problem of perception. Proceeding from this paradigm, the paper proposes ‘experimental critical OLP’ as a new research program in experimental philosophy that avoids apparent non-sequiturs of OLP, extends and transforms experimental philosophy’s ‘sources program’, and provides a promising new strategy for deploying empirical findings about how people ordinarily talk and think about phenomena, to address longstanding philosophical problems.

Taking the formal analogies between black holes and classical thermodynamics seriously seems to first require that classical thermodynamics applies in relativistic regimes. Yet, by scrutinizing how classical temperature is extended into special relativity, I argue that the concept falls apart. I examine four consilient procedures for establishing the classical temperature: the Carnot process, the thermometer, kinetic theory, and black-body radiation. I argue that their relativistic counterparts demonstrate no such consilience in defining the relativistic temperature. As such, classical temperature doesn’t appear (...) to survive a relativistic extension. I suggest two interpretations for this situation: eliminativism akin to simultaneity, or pluralism akin to rotation. (shrink)

Conventional wisdom holds that the von Neumann entropy corresponds to thermodynamic entropy, but Hemmo and Shenker (2006) have recently argued against this view by attacking von Neumann's (1955) argument. I argue that Hemmo and Shenker's arguments fail due to several misunderstandings: about statistical-mechanical and thermodynamic domains of applicability, about the nature of mixed states, and about the role of approximations in physics. As a result, their arguments fail in all cases: in the single-particle case, the finite particles case, and the (...) infinite particles case. (shrink)

Stereotypes shape inferences in philosophical thought, political discourse, and everyday life. These inferences are routinely made when thinkers engage in language comprehension or production: We make them whenever we hear, read, or formulate stories, reports, philosophical case-descriptions, or premises of arguments – on virtually any topic. These inferences are largely automatic: largely unconscious, non-intentional, and effortless. Accordingly, they shape our thought in ways we can properly understand only by complementing traditional forms of philosophical analysis with experimental methods from psycholinguistics. This (...) paper seeks, first, to bring out the wider philosophical relevance of stereotypical inference, well beyond familiar topics like gender and race. Second, we wish to provide philosophers with a toolkit to experimentally study these ubiquitous inferences and what intuitions they may generate. This paper explains what stereotypes are, and why they matter to current and traditional concerns in philosophy – experimental, analytic, and applied. It then assembles a psycholinguistic toolkit and demonstrates through two studies how potentially questionnaire-based measures can be combined with process measures to garner evidence for specific stereotypical inferences and study when they ‘go through’ and influence our thinking.

How does experimental philosophy address philosophical questions and problems? That is: What projects does experimental philosophy pursue? What is their philosophical relevance? And what empirical methods do they employ? Answers to these questions will reveal how experimental philosophy can contribute to the longstanding ambition of placing philosophy on the ‘secure path of a science’, as Kant put it. We argue that experimental philosophy has introduced a new methodological perspective – a ‘meta-philosophical naturalism’ that addresses philosophical questions about a phenomenon by (...) empirically investigating how people think about this phenomenon. This chapter asks how this novel perspective can be successfully implemented: How can the empirical investigation of how people think about something address genuinely philosophical problems? And what methods – and, specifically, what methods beyond the questionnaire – can this investigation employ? We first review core projects of experimental philosophy and raise the question of their philosophical relevance. For ambitious answers, we turn to experimental philosophy’s most direct historical precursor, mid-20th century ordinary language philosophy, and discuss empirical implementations of two of its research programmes that use experimental methods from psycholinguistics and corpus methods from the digital humanities.

Intuitive judgments elicited by verbal case-descriptions play key roles in philosophical problem-setting and argument. Experimental philosophy's ‘sources project’ seeks to develop psychological explanations of philosophically relevant intuitions which help us assess our warrant for accepting them. This article develops a psycholinguistic explanation of intuitions prompted by philosophical case-descriptions. For proof of concept, we target intuitions underlying a classic paradox about perception, trace them to stereotype-driven inferences automatically executed in verb comprehension, and employ a forced-choice plausibility-ranking task to elicit the relevant (...) stereotypical associations of perception- and appearance-verbs. We obtain a debunking explanation that resolves the philosophical paradox. (shrink)

Preparing general relativity for quantization in the Hamiltonian approach leads to the `problem of time,' rendering the world fundamentally timeless. One proposed solution is the `thermal time hypothesis,' which defines time in terms of states representing systems in thermal equilibrium. On this view, time is supposed to emerge thermodynamically even in a fundamentally timeless context. Here, I develop the worry that the thermal time hypothesis requires dynamics -- and hence time -- to get off the ground, thereby running into worries (...) of circularity. (shrink)

: Two common ways of explaining akrasia will be presented, one which focuses on strength of desire and the other which focuses on action issuing from practical judgment. Though each is intuitive in a certain way, they both fail as explanations of the most interesting cases of akrasia. Spinoza 's own thoughts on bondage and the affects follow, from which a Spinozist explanation of akrasia is constructed. This account is based in Spinoza 's mechanistic psychology of cognitive affects. Because Spinoza (...) 's account explains action asissuing from modes of mind that are both cognitive and affective, it captures the intuitions that motivate the two traditional views while avoiding the pitfalls that result from their one‐sided approaches. This project will allow us a fuller understanding of Spinozist moral psychology. In addition to this historical value, the Spinozist theory may offer a satisfactory explanation of certain hard cases of akrasia while avoiding the problems be set by other theories. For this reason, the Spinozist account could also be seen as a useful contribution to our philosophical understanding of the phenomenon of akrasia. (shrink)

Empirical evidence shows that people have multiple time-biases. One is near-bias, another is future-bias, and a third is present-bias. Philosophers are concerned with the normative status of these time-biases. They have argued that, at least in part, the normative status of these biases depends on the extent to which they tend to promote, or frustrate, wellbeing, where “wellbeing” is taken to be of fundamental value. Since near-bias is thought to be associated with impulsivity, lack of self-control, and poor long-term health (...) and financial outcomes, it has often been supposed that it is associated with lower wellbeing. On those grounds, philosophers have argued that near-bias is rationally impermissible. By contrast, philosophical views about the normative status of future-bias have been mixed, with some arguing that future-bias is impermissible because, they think, it frustrates wellbeing, and others arguing that it is at least permissible (and perhaps obligatory) because it is the product of mechanisms whose functioning can be expected to promote wellbeing. However, to date there are no studies that have directly probed how time-biases correlate with wellbeing. Since it's not a settled matter which psychological mechanisms underlie time-biases, it is not uncontroversial which things serve as proxies for these preferences. We directly empirically investigate the connection between time-biases and measures of wellbeing, to see which of these biases is associated with promoting, or frustrating wellbeing. Contrary to expectation, we found no evidence that near-bias or present-bias are associated with frustrating wellbeing on any of the constructs we measured. On the other hand, and contrary to what some philosophers have supposed, we found that future-bias was associated with higher measures of wellbeing on several measures. We consider the implications of these findings for the evaluation of the normative status of these time biases. (shrink)

This paper provides new tools for philosophical argument analysis and fresh empirical foundations for ‘critical’ ordinary language philosophy. Language comprehension routinely involves stereotypical inferences with contextual defeaters. J.L. Austin’s Sense and Sensibilia first mooted the idea that contextually inappropriate stereotypical inferences from verbal case-descriptions drive some philosophical paradoxes; these engender philosophical problems that can be resolved by exposing the underlying fallacies. We build on psycholinguistic research on salience effects to explain when and why even perfectly competent speakers cannot help making (...) stereotypical inferences which are contextually inappropriate. We analyse a classical paradox about perception, suggest it relies on contextually inappropriate stereotypical inferences from appearance-verbs, and show that the conditions we identified as leading to contextually inappropriate stereotypical inferences are met in formulations of the paradox. Three experiments use a forced-choice plausibility-ranking task to document the predicted inappropriate inferences, in English, German, and Japanese. The cross-linguistic study allows us to assess the wider relevance of the proposed analysis. Our findings open up new perspectives for ‘evidential’ experimental philosophy. (shrink)

Some conceptions of the role of philosophers in climate change focus mainly on theoretical progress in philosophy, or on philosophers as individual citizens. Against these views, I defend a skill view: philosophers should use our characteristic skills as philosophers to combat climate change by integrating it into our teaching, research, service, and community engagement. A focus on theoretical progress, citizenship, expertise, virtue, ability, social role, or power, rather than on skill, can allow for some of these contributions. But the skill (...) view, I argue, uniquely captures the breadth of philosophers’ role in climate change; promises to make us more effective in practice; and offers a compelling way to overcome our own lingering climate denial by integrating climate change into all aspects of philosophical activity.

Many philosophical thought experiments and arguments involve unusual cases. We present empirical reasons to doubt the reliability of intuitive judgments and conclusions about such cases. Inferences and intuitions prompted by verbal case descriptions are influenced by routine comprehension processes which invoke stereotypes. We build on psycholinguistic findings to determine conditions under which the stereotype associated with the most salient sense of a word predictably supports inappropriate inferences from descriptions of unusual (stereotype-divergent) cases. We conduct an experiment that combines plausibility ratings (...) with pupillometry to document this “salience bias.” We find that under certain conditions, competent speakers automatically make stereotypical inferences they know to be inappropriate.

Until recently, experimental philosophy has been associated with the questionnaire-based study of intuitions; however, experimental philosophers now adapt a wide range of empirical methods for new philosophical purposes. New methods include paradigms for behavioural experiments from across the social sciences as well as computational methods from the digital humanities that can process large bodies of text and evidence. This book offers an accessible overview of these exciting innovations. The volume brings together established and emerging research leaders from several areas of (...) experimental philosophy to explore how new empirical methods can contribute to philosophical debates. Each chapter presents one or several methods new to experimental philosophy, demonstrating their application in a key area of philosophy and discussing their strengths and limitations. Methods covered include eye tracking, virtual reality technology, neuroimaging, statistical learning, and experimental economics as well as corpus linguistics, visualisation techniques and data and text mining. The volume explores their use in moral philosophy and moral psychology, epistemology, philosophy of science, metaphysics, philosophy of language, philosophy of mind and the history of ideas. Methodological Advances in Experimental Philosophy is essential reading for undergraduates, graduate students and researchers working in experimental philosophy. (shrink)

In Everettian quantum mechanics, justifications for the Born rule appeal to self-locating uncertainty or decision theory. Such justifications have focused exclusively on a pure-state Everettian multiverse, represented by a wave function. Recent works in quantum foundations suggest that it is viable to consider a mixed-state Everettian multiverse, represented by a (mixed-state) density matrix. Here, we develop the conceptual foundations for decoherence and branching in a mixed-state multiverse, and extend the standard Everettian justifications for the Born rule to this setting. This (...) extended framework provides a unification of 'classical' and 'quantum' probabilities, and additional theoretical benefits, for the Everettian picture. (shrink)

We blame faulty brakes for a car crash, or rain for our bad mood. This “merely causal” blame is usually seen as uninteresting. I argue that it is crucial for understanding the interpersonal blame with which we target ourselves and each other. The two are often difficult to distinguish, in a way that plagues philosophical discussions of blame. And interpersonal blame is distinctive, I argue, partly in its causal focus: its attention to a person as cause. I argue that this (...) causal focus helps explain several central characteristics of interpersonal blame: its tendency to exaggerate a person’s causal role, its weakening through attention to personal history or thoughts about determinism, its characteristic ‘force’ or ‘sting’, and our sense that blame is often harmful or unfair. I conclude by drawing out one implication of blame's causal focus: in a certain range of cases, blame is partly under our voluntary control. (shrink)

Experimental philosophy’s much-discussed ‘restrictionist’ program seeks to delineate the extent to which philosophers may legitimately rely on intuitions about possible cases. The present paper shows that this program can be (i) put to the service of diagnostic problem-resolution (in the wake of J.L. Austin) and (ii) pursued by constructing and experimentally testing psycholinguistic explanations of intuitions which expose their lack of evidentiary value: The paper develops a psycholinguistic explanation of paradoxical intuitions that are prompted by verbal case-descriptions, and presents two (...) experiments that support the explanation. This debunking explanation helps resolve philosophical paradoxes about perception (known as ‘arguments from hallucination’). (shrink)

I argue that influential recent discussions have whitewashed blame, characterizing it in ways that deemphasize or ignore its morally problematic features. I distinguish “definitional,” “creeping,” and “emphasis” whitewash, and argue that they play a central role in overall endorsements of blame by T.M. Scanlon, George Sher, and Miranda Fricker. In particular, these endorsements treat blame as appropriate by definition (Scanlon), or as little more than a wish (Sher), and infer from blame's having one useful function that it is a good (...) practice overall (Fricker). I use an analogy with revenge to illustrate the mechanisms of whitewashing, including broadening a concept to include available alternatives to it and inference from one feature of a practice to an overall conclusion about that practice. Several features of blame make it particularly prone to whitewashing, including blamers' personal or emotional stake in blaming and widespread disagreement about the nature of blame. I argue that a non‐whitewashing treatment of blame must pay closer attention both to blame's harms, and to comparisons between blame and alternative, non‐blaming reactions. (shrink)

Psycholinguistic methods hold great promise for experimental philosophy. Many philosophical thought experiments and arguments proceed from verbal descriptions of possible cases. Many relevant intuitions and conclusions are driven by spontaneous inferences about what else must also be true in the cases described. Such inferences are continually made in language comprehension and production. This chapter explains how methods from psycholinguistics can be employed to study such routine automatic inferences, with a view to assessing intuitions and reconstructing arguments. We demonstrate how plausibility (...) ratings, pupillometry, and reading time measurements can be used to examine hypotheses about automatic inferences in speech and text comprehension. Two experiments on inferences from polysemous (perception-)verbs provide evidence of a potentially consequential ‘salience bias’. Findings help assess intuitions about unusual cases and analyse a philosophical paradox (‘argument from hallucination’). The paper thus illustrates how we can adapt psycholinguistic methods for philosophical purposes and demonstrates the methods’ philosophical usefulness. (shrink)

Dematerialization can be taken variously as meaning less materials used in objects technically, a less materialistic outlook on consumption, or as the virtualization of communication and interaction. These ideas are reviewed here. Considering material culture and technoculture in this light raises questions about contemporary materialism and technology more generally as well, where smaller is not necessarily simpler, and where smaller may not even be less.

The second article, in which the author suggests an analysis of other three authors' state of nature models and tries to define the role of the models in their respective law concepts. The analysis demonstrates that all three models share same basic idea, which is the concept of an independent reasonable individual; this very idea is what these different models are based upon. The concept of an individual itself does not have a substantiation.

Drawing on recent work in psychology, I argue that there are not one but several distinct virtues pertaining to willpower or strength of will: (1) the disposition to exercise willpower; (2) a distinctively volitional kind of modesty, or moderation in exposing oneself to volitional strain; and (3) a distinctively volitional kind of confidence, or proper inattention to the possibility of volitional failure. A multiple-virtue conception of willpower, I argue, provides a useful framework for cultivating a good relationship to one’s own (...) volitional limitations; resists an unhealthy emphasis on ‘powering through’ volitional obstacles; and avoids controversial empirical assumptions without giving up on making progress in ethical thought about willpower. I answer objections that the latter two virtues are incompatible, and that they add little of value to hope or belief in success. I then argue that combining these virtues requires a kind of flexible attention which, while difficult, is both psychologically possible and desirable. (shrink)

The paper builds on a methodological idea from experimental philosophy and on findings from psycholinguistics, to develop and defend ordinary language analysis (OLA) as practiced in J.L. Austin’s Sense and Sensibilia. That attack on sense-datum theories of perception focuses on the argument from illusion. Through a case-study on this paradoxical argument, the present paper argues for a form of OLA which is psychologically informed, seeks to expose epistemic, rather than semantic, defects in paradoxical arguments, and is immune to the main (...) objections to ordinary language philosophising, including those arising from the semantic/pragmatics distinction: A key project in current experimental philosophy is to develop psychological explanations of philosophically relevant intuitions that help us determine what warrant thinkers have for accepting them. Psycholinguistic work on the role of stereotypes in verb-comprehension has shown that intuitive judgments can be generated by automatic cognitive processes that duplicate both semantic and pragmatic inferences and are shaped by dominant uses of words. For systematic reasons, philosophers are prone to unwittingly deviate from such dominant uses. Where this happens, they are liable to automatically infer unwarranted conclusions that strike them as intuitively compelling. OLA helps us to determine those dominant uses, to identify unwitting deviations from them, and thus to expose unwarranted intuitions – e.g., in the premises of paradoxical arguments. Ordinary language does not determine the bounds of sense but shapes our leaps of thought. The paper shows how this enables its ‘Austinian’ analysis to contribute to a novel, epistemic, resolution of philosophical paradoxes and problems. (shrink)

The article deals with currents and tides. We look at the history of their observation in antiquity as well as alternative theories, designed to explain their nature. Major theories accessed are those by Aristotle, Posidonius and Seneca. Special attention is given to ancient explanation of the phenomenon of the periodical change of the stream in Euripus’ channel. Throughout we refl ect on an analogy between natural phenomena and the processes occurring in living organisms, common to our philosophers of nature, as (...) well as the peculiarities of their interpretation of the theory of mutual transformation of the elements. Besides, it is important to note the place of the method of analogy in their observations and theoretical constructions. (shrink)

Steven Spielberg‘s filmed representation of the Holocaust dares its viewers to experience, as secondary witnesses, atrocities committed by the Nazis in Poland. The film is yet another form of testimonial narrative (audio-visual but lacking a full historical context, except for a few on-screen titles) which aligns the survivors, who have come to be known as the Schindler Jews, and their descendants, on the one hand, and Spielberg‘s cameraman (comparable to an internalized narrator), Spielberg the film director (an external, omniscient narrator), (...) and the film-theater audience, on the other.

This is a transcript of a conversation between P F Strawson and Gareth Evans in 1973, filmed for The Open University.

On September 11, 2001, many of us experienced life as what it is not: we lived an extreme instance of the spectacle, of the sublime outside the realm of ethics. Starting with a few compelling questions that the media representations of the attack on the New York World Trade Center inevitably raise, this paper explores a series of similarities, continuums, and extrapolations of the aesthetic in different types of discourse from Friedrich Schiller to Guy Debord. My assessment of the individual‘s (...) dissolution in the ritual (former dissident and present Czech President Václav Havel‘s phrase) rejects the bleak Marxist theories of manipulation, without overlooking, at the same time, the potential dangers of unfreedom that the process of surrendering to the spectacle implies. Living life as show time may ultimately, and oxymoronically, prove to be the only option toward an infinitude of choices. (shrink)

Eugene Afonasin highlights the wealth of information on Pythagoras and his tradition preserved in Clement of Alexandria’s Stromateis and presents them against the background of Later Platonic philosophy. He  rst outlines what Clement knew about the Pythagoreans, and then what he made of the Pythagorean ideal and how he reinterpreted it for his own purposes. Clement clearly occupies an intermediate position between the Neopythagorean biographical tradition, rmly based on Nicomachus, and that more or less vague and difuse literary (...) situation which preceded the later developments, and in this respect is a very good source, worth studying for its own sake and as supplementary material which can help to understand the great Pythagorean synthesis attempted by Iamblichus. Developing their variants of the “exhortation to philosophy” (protreptikoi logoi), these men were much concerned with the educational value of the Pythagorean way of life rather than biographical circumstances, designed to place the ancient sage in the proper cultural context.

Responsible innovation is centered around the ideal that societal stakeholders are entitled to participate in scientific and technological decision-making by voicing their needs and worries. Individuals who believe in science conspiracies (referred to here as ‘science conspiracists’) pose a challenge to implementing this ideal because it is not clear under what conditions their inclusion in responsible innovation exercises is possible and advisable. Yet precisely because of this uncertain status, science conspiracists constitute an instructive case in point to travel towards the (...) edges of inclusion and understand how we draw the line between ‘includables' and ‘unincludables’. In this paper, we seek to explore this relationship between responsible innovation and science conspiracism by using the method of thought experimentaiton. We test four possible exclusion criteria for science conspiracists. We conclude by revisiting the relationship between conspiracism and responsible innovation and sketching a novel perspective on the ideal of stakeholder inclusion. (shrink)

The paper is devoted to Aristotle's solution to Meno's paradox: a person cannot search for what he knows -- he knows it, and there is no need to search for such a thing -- nor for what he doesn't know -- since he doesn't know what he's searching for. The autor argues that Aristotle proposes solutions of this paradox for every stage of cognition, not only for exercising available scientific knowledge as regarded by most Aristotelian scholars. He puts more focus (...) on the importance of the distinction between 'progignoskein' (pre-existing cognition) and 'proepistasthai' (pre-existong knowledge) for Aristotle's solution of this paradox.

An important strand of current experimental philosophy promotes a new kind of methodological naturalism. This chapter argues that this new ‘metaphilosophical naturalism’ is fundamentally consistent with key tenets of Wittgenstein’s metaphilosophy, and can provide empirical foundations for therapeutic conceptions of philosophy. Metaphilosophical naturalism invites us to contribute to the resolution of philosophical problems about X by turning to scientific findings about the way we think about X – in general or when doing philosophy. This new naturalism encourages us to use (...) resources from psychology that can empirically vindicate precisely some of the most controversial aspects of Wittgenstein’s conception of philosophy: They can establish the need, and provide key tools, for something worth calling ‘therapy’, in philosophy. As ‘pudding proof’ this chapter shows how methods and findings from psycholinguistics motivate and facilitate a therapeutic approach to a characteristically philosophical problem: ‘the problem of perception’.

Coffee and tea are two beverages commonly-consumed around the world. Therefore, there is much research regarding their physiological effects. However, less is known about their psychological meanings. Derived from a predicted lay association between coffee and arousal, we posit that exposure to coffee-related cues should increase arousal, even in the absence of actual ingestion, relative to exposure to tea-related cues. We further suggest that higher arousal levels should facilitate a concrete level of mental construal as conceptualized by Construal Level Theory. (...) In four experiments, we find that coffee cues prompted participants to see temporal distances as shorter and to think in more concrete, precise terms. Both subjective and physiological arousal explain the effects. We situate our work in the literature that connects food and beverage to cognition or decision-making. We also discuss the applied relevance of our results as coffee and tea are among the most prevalent beverages globally. (shrink)
