2021 marks Dylan's 80th birthday and his 60th year in the music world. It invites us to look back on his career and the multitudes that it contains. Is he a song and dance man? A political hero? A protest singer? A self-portrait artist who has yet to paint his masterpiece? Is he Shakespeare in the alley? The greatest living exponent of American music? An ironsmith? Internet radio DJ? Poet (who knows it)? Is he a spiritual and religious parking meter? (...) Judas? The voice of a generation or a false prophet, jokerman, and thief? Dylan is all these and none. The essays in this book explore the Nobel laureate’s masks, collectively reflecting upon their meaning through time, change, movement, and age. They are written by wonderful and diverse set of contributors, all here for his 80th birthday bash: celebrated Dylanologists like Michael Gray and Laura Tenschert; recording artists such as Robyn Hitchcock, Barb Jungr, Amy Rigby, and Emma Swift; and 'the professors’ who all like his looks: David Boucher, Anne Margaret Daniel, Ray Monk, Galen Strawson, and more.

‘Poor Bertie’ Beatrice Webb wrote after receiving a visit from Bertrand Russell in 1931, ‘he has made a mess of his life and he knows it’. In the 1931 version of his Autobiography, Russell himself seemed to share Webb’s estimate of his achievements. Emotionally, intellectually and politically, he wrote, his life had been a failure. This sense of failure pervades the second volume of Ray Monk’s engrossing and insightful biography. At its heart is the failure of Russell’s marriages to Dora (...) Black and Patricia (Peter) Spence, his poor relationships with his children John and Kate, and the decline in his reputation as a philosopher. Russell, who had changed the direction of philosophy irrevocably, was in later years unable to find permanent academic employment in Britain, ousted from his professorship at the City College of New York because of his views on sex and marriage, and was reduced to giving nonspecialist lectures at a foundation established by the Philadelphia philanthropist Albert C. Barnes. Eventually in 1944 he returned to Cambridge, but by then the philosophical world was in the grip of Ludwig Wittgenstein’s ideas, and Russell was largely ignored. (shrink)

Alguns anos atrás, cheguei ao ponto onde eu normalmente pode dizer a partir do título de um livro, ou pelo menos a partir dos títulos do capítulo, que tipos de erros filosóficos serão feitas e com que freqüência. No caso de obras nominalmente científicas, estas podem ser largamente restritas a certos capítulos que enceram filosóficos ou tentam tirar conclusões gerais sobre o significado ou significado a longo prazo do trabalho. Normalmente entretanto as matérias científicas do fato são misturado generosa com (...) o jargão filosófico a respeito do que estes fatos significam. As distinções claras que Wittgenstein descreveu cerca de 80 anos atrás entre questões científicas e suas descrições por vários jogos de linguagem são raramente levados em consideração, e assim um é alternadamente impressionados pela ciência e desanimado por sua incoerente Análise.

Ele está encantado com modelos, teorias e conceitos, e o impulso de explicar, enquanto Wittgenstein nos mostrou que só precisamos descrever, e que as teorias, conceitos etc, são apenas maneiras de usar a linguagem (jogos de linguagem) que têm valor apenas na medida em que eles têm uma clara teste (claro que os verdadeiros, ou como John Searle (crítico mais famoso da AI) gosta de dizer, claro condições de satisfação (COS)).

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

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

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

You are morally permitted to save your friend at the expense of a few strangers, but not at the expense of very many. However, there seems no number of strangers that marks a precise upper bound here. Consequently, there are borderline cases of groups at the expense of which you are permitted to save your friend. This essay discusses the question of what explains ethical vagueness like this, arguing that there are interesting metaethical consequences of various explanations.

Nearly everyone prefers pain to be in the past rather than the future. This seems like a rationally permissible preference. But I argue that appearances are misleading, and that future-biased preferences are in fact irrational. My argument appeals to trade-offs between hedonic experiences and other goods. I argue that we are rationally required to adopt an exchange rate between a hedonic experience and another type of good that stays fixed, regardless of whether the hedonic experience is in the past or (...) future.

How wrong is it to deceive someone into sex by lying, say, about one's profession? The answer is seriously wrong when the liar's actual profession would be a deal breaker for the victim of the deception: this deception vitiates the victim's sexual consent, and it is seriously wrong to have sex with someone while lacking his or her consent.

The anglophone philosophy profession has a well-known problem with gender equity. A sig-nificant aspect of the problem is the fact that there are simply so many more male philoso-phers than female philosophers among students and faculty alike. The problem is at its stark-est at the faculty level, where only 22% - 24% of philosophers are female in the United States (Van Camp 2014), the United Kingdom (Beebee & Saul 2011) and Australia (Goddard 2008).<1> While this is a result of the (...) percentage of women declining at each point through-out the standard career trajectory, recent large-scale studies in the United States (Paxton et al. 2012) and Australia (Goddard et al. 2008) have identified a key drop-off point as the transi-tion between taking introductory classes and majoring in philosophy. So why do dispropor-tionately few female students choose to major in philosophy? (shrink)

Though one of anti-intellectualism’s key historical figures, Henri Bergson’s thought has not played a significant role in ongoing discussions of that topic. This paper attempts to help change this situation by discussing the notion at the centre of Bergson’s anti-intellectualism (namely, intuition) alongside the notion at the centre of a central form of contemporary anti-intellectualism (namely, know-how or skill). In doing so, it focuses on perhaps the most common objection to both Bergson and contemporary anti-intellectualists: that their anti-intellectualisms are rather (...) forms of irrationalism. It argues that in fact only a narrow charge of irrationalism applies to Bergsonian intuition and that a form of contemporary anti-intellectualism may offer help in responding to this remaining accusation.

In an influential paper, L. A. Paul argues that one cannot rationally decide whether to have children. In particular, she argues that such a decision is intractable for standard decision theory. Paul's central argument in this paper rests on the claim that becoming a parent is ``epistemically transformative''---prior to becoming a parent, it is impossible to know what being a parent is like. Paul argues that because parenting is epistemically transformative, one cannot estimate the values of the various outcomes of (...) a decision whether to become a parent. In response, we argue that it is possible to estimate the value of epistemically transformative experiences. Therefore, there is no special difficulty involved in deciding whether to undergo epistemically transformative experiences. Insofar as major life decisions do pose a challenge to decision theory, we suggest that this is because they often involve separate, familiar problems. (shrink)

This paper argues for a reinterpretation of the skill analogy in virtue ethics. It argues that the skill analogy should not be understood as proposing that being virtuous is analogous to possessing a practical skill but, rather, as proposing that being virtuous is analogous to being a good occupant of a skill-involving role. The paper argues for this by engaging with various standard objections to the analogy, two recent defences of it, and Aristotle’s treatment of it in developing his account (...) of virtue in the Nicomachean Ethics. It aims to show that neither virtue nor the skill analogy is correctly understood without recourse to the notion of a role and that once we have recourse to that notion, many objections to the analogy are met.

There is, in some quarters, concern about high–level machine intelligence and superintelligent AI coming up in a few decades, bringing with it significant risks for humanity. In other quarters, these issues are ignored or considered science fiction. We wanted to clarify what the distribution of opinions actually is, what probability the best experts currently assign to high–level machine intelligence coming up within a particular time–frame, which risks they see with that development, and how fast they see these developing. We thus (...) designed a brief questionnaire and distributed it to four groups of experts in 2012/2013. The median estimate of respondents was for a one in two chance that high-level machine intelligence will be developed around 2040-2050, rising to a nine in ten chance by 2075. Experts expect that systems will move on to superintelligence in less than 30 years thereafter. They estimate the chance is about one in three that this development turns out to be ‘bad’ or ‘extremely bad’ for humanity. (shrink)

Qualitative fieldwork research on sensitive topics sometimes requires that interviewees be granted confidentiality and anonymity. When qualitative researchers later publish their findings, they must ensure that any statements obtained during fieldwork interviews cannot be traced back to the interviewees. Given these protections to interviewees, the integrity of the published findings cannot usually be verified or replicated by third parties, and the scholarly community must trust the word of qualitative researchers when they publish their results. This trust is fundamentally abused, however, (...) when researchers publish articles reporting qualitative fieldwork data that they never collected. Using only publicly available information, I argue that a 2017 article in an Elsevier foreign policy and international relations journal presents anonymised fieldwork interviews that could not have occurred as described. As an exercise in post-publication peer review (PPPR), this paper examines the evidence that calls into question the reliability of the putative fieldwork quotations. I show further that the 2017 article is not a unique case. The anonymity and confidentiality protections common in some areas of research create an ethical problem: the protections necessary for obtaining research data can be used as a cover to hide substandard research practices as well as research misconduct.

Credences are beliefs about evidential probabilities. We give the view an assessment-sensitive formulation, show how it evades the standard objections, and give several arguments in support.

Most of us are “time-biased” in preferring pains to be past rather than future and pleasures to be future rather than past. However, it turns out that if you are risk averse and time-biased, then you can be turned into a “pain pump”—in order to insure yourself against misfortune, you will take a series of pills which leaves you with more pain and better off in no respect. Since this vulnerability seems rationally impermissible, while time-bias and risk aversion seem rationally (...) permissible, we are left with a puzzle. (shrink)

Some contextually sensitive expressions are such that their context independent conventional meanings need to be in some way supplemented in context for the expressions to secure semantic values in those contexts. As we’ll see, it is not clear that there is a paradigm here, but ‘he’ used demonstratively is a clear example of such an expression. Call expressions of this sort supplementives in order to highlight the fact that their context independent meanings need to be supplemented in context for them (...) to have semantic values relative to the context. Many philosophers and linguists think that there is a lot of contextual sensitivity in natural language that goes well beyond the pure indexicals and supplementives like ‘he’. Constructions/expressions that are good candidates for being contextually sensitive include: quantifiers, gradable adjectives including “predicates of personal taste”, modals, conditionals, possessives and relational expressions taking implicit arguments. It would appear that in none of these cases does the expression/construction in question have a context independent meaning that when placed in context suffices to secure a semantic value for the expression/construction in the context. In each case, some sort of supplementation is required to do this. Hence, all these expressions are supplementives in my sense. For a given supplementive, the question arises as to what the mechanism is for supplementing its conventional meanings in context so as to secure a semantic value for it in context. That is, what form does the supplementation take? The question also arises as to whether different supplementives require different kinds of supplementation. Let us call an account of what, in addition to its conventional meaning, secures a semantic value for a supplementive in context a metasemantics for that supplementive. So we can put our two questions thus: what is the proper metasemantics for a given supplementive; and do all supplementives have the same metasemantics? In the present work, I sketch the metasemantics I formulated for demonstratives in earlier work. Next, I briefly consider a number of other supplementives that I think the metasemantics I propose plausibly applies to and explain why I think that. Finally, I consider the prospects for extending the account to all supplementives. In so doing, I take up arguments due to Michael Glanzberg to the effect that supplementives are governed by two different metasemantics and attempt to respond to them. (shrink)

This article is an annotated bibliography, listing and discussing research by, on, and in dialogue with Gilbert Ryle.

What sort of logic do we get if we adopt a supervaluational semantics for vagueness? As it turns out, the answer depends crucially on how the standard notion of validity as truth preservation is recasted. There are several ways of doing that within a supervaluational framework, the main alternative being between “global” construals (e.g., an argument is valid iff it preserves truth-under-all-precisifications) and “local” construals (an argument is valid iff, under all precisifications, it preserves truth). The former alternative is by (...) far more popular, but I argue in favor of the latter, for (i) it does not suffer from a number of serious objections, and (ii) it makes it possible to restore global validity as a defined notion.

So-called money pump arguments aim to show that intransitive preferences are irrational because they will lead someone to accept a series of deals that leaves his/her financially worse off and better off in no respect. A common response to these arguments is the foresight response, which counters that the agent in question may see the exploitation coming, and refuse to trade at all. To obviate this response, I offer a “deluxe money pump argument” that applies dominance reasoning to a modified (...) money pump case. (shrink)

Will future lethal autonomous weapon systems (LAWS), or ‘killer robots’, be a threat to humanity? The European Parliament has called for a moratorium or ban of LAWS; the ‘Contracting Parties to the Geneva Convention at the United Nations’ are presently discussing such a ban, which is supported by the great majority of writers and campaigners on the issue. However, the main arguments in favour of a ban are unsound. LAWS do not support extrajudicial killings, they do not take responsibility away (...) from humans; in fact they increase the abil-ity to hold humans accountable for war crimes. Using LAWS in war would probably reduce human suffering overall. Finally, the availability of LAWS would probably not increase the probability of war or other lethal conflict—especially as compared to extant remote-controlled weapons. The widespread fear of killer robots is unfounded: They are probably good news. (shrink)

In her 2004 book Carol Gould addresses the fundamental issue of democratizing globalization, that is to say of finding ways to open transnational institutions and communities to democratic participation by those widely affected by their decisions. The book develops a framework for expanding participation in crossborder decisions, arguing for a broader understanding of human rights and introducing a new role for the ideas of care and solidarity at a distance. Reinterpreting the idea of universality to accommodate a multiplicity of cultural (...) perspectives, the author takes up a number of applied issues, including the persistence of racism, cultural rights, women's human rights, the democratic management of firms, the use of the Internet to enhance political participation, and the importance of empathy and genuine democracy in understanding terrorism and responding to it. Accessibly written with a minimum of technical jargon this is a major contribution to political philosophy. (shrink)

This paper presents an account of Iris Murdoch's engagement with the work of Martin Heidegger. It covers her early discussions and evaluations of him in The Sovereignty of Good, through to her late Heidegger manuscript, covering both his early and late work. It details the significant changes that occur in her evaluation of him, as well as the key sympathies identified and criticisms developed in the late manuscript. The focus is on her insistence that only 'the Good', and not Heidegger's (...) 'Being', can fill the space left by the traditional Western God, and of the related failure in Heidegger to account properly for value. (shrink)

In Wrongs and Crimes, Victor Tadros clarifies the debate about whether consent needs to be communicated by separating the question of whether consent requires expressive behaviour from the question of whether it requires “uptake” in the form of comprehension by the consent-receiver. Once this distinction is drawn, Tadros argues both that consent does not require uptake and that consent does not require expressive behaviour that provides evidence to the consent-receiver. As a result, Tadros takes the view that consent requires an (...) attempt to communicate, but nothing more. While I have found Tadros’s arguments for this conclusion intriguing and challenging, I am yet to be persuaded by them. In this essay, I try to say why. (shrink)

The contribution of the body to cognition and control in natural and artificial agents is increasingly described as “off-loading computation from the brain to the body”, where the body is said to perform “morphological computation”. Our investigation of four characteristic cases of morphological computation in animals and robots shows that the ‘off-loading’ perspective is misleading. Actually, the contribution of body morphology to cognition and control is rarely computational, in any useful sense of the word. We thus distinguish (1) morphology that (...) facilitates control, (2) morphology that facilitates perception and the rare cases of (3) morphological computation proper, such as ‘reservoir computing.’ where the body is actually used for computation. This result contributes to the understanding of the relation between embodiment and computation: The question for robot design and cognitive science is not whether computation is offloaded to the body, but to what extent the body facilitates cognition and control – how it contributes to the overall ‘orchestration’ of intelligent behaviour.

Cognitive penetration of perception is the idea that what we see is influenced by such states as beliefs, expectations, and so on. A perceptual belief that results from cognitive penetration may be less justified than a nonpenetrated one. Inferentialism is a kind of internalist view that tries to account for this by claiming that some experiences are epistemically evaluable, on the basis of why the perceiver has that experience, and the familiar canons of good inference provide the appropriate standards by (...) which experiences are evaluated. I examine recent defenses of inferentialism by Susanna Siegel, Peter Markie, and Matthew McGrath and argue that the prospects for inferentialism are dim. (shrink)

One logic or many? I say—many. Or rather, I say there is one logic for each way of specifying the class of all possible circumstances, or models, i.e., all ways of interpreting a given language. But because there is no unique way of doing this, I say there is no unique logic except in a relative sense. Indeed, given any two competing logical theories T1 and T2 (in the same language) one could always consider their common core, T, and settle (...) on that theory. So, given any language L, one could settle on the minimal logic T0 corresponding to the common core shared by all competitors. That would be a way of resisting relativism, as long as one is willing to redraw the bounds of logic accordingly. However, such a minimal theory T0 may be empty if the syntax of L contains no special ingredients the interpretation of which is independent of the specification of the relevant L-models. And generally—I argue—this is indeed the case. (shrink)

The anglophone philosophy profession has a well-known problem with gender equity. A sig-nificant aspect of the problem is the fact that there are simply so many more male philoso-phers than female philosophers among students and faculty alike. The problem is at its stark-est at the faculty level, where only 22% - 24% of philosophers are female in the United States (Van Camp 2014), the United Kingdom (Beebee & Saul 2011) and Australia (Goddard 2008).<1> While this is a result of the (...) percentage of women declining at each point through-out the standard career trajectory, recent large-scale studies in the United States (Paxton et al. 2012) and Australia (Goddard et al. 2008) have identified a key drop-off point as the transi-tion between taking introductory classes and majoring in philosophy. So why do dispropor-tionately few female students choose to major in philosophy? (shrink)

This paper aims to shed light on an underexplored aspect of Gilbert Ryle’s interest in the notion of “knowing-how”. It is argued that in addition to his motive of discounting a certain theory of mind, his interest in the notion also stemmed (and perhaps stemmed more deeply) from two ethical interests: one concerning his own life as a philosopher and whether the philosopher has any meaningful task, and one concerning the ancient issue of whether virtue is a kind of knowledge. (...) It is argued that Ryle saw know-how as crucial in both respects and that he continued to be interested in these ethical issues throughout his career. (shrink)

A classic objection to act-consequentialism is that it is overdemanding: it requires agents to bear too many costs for the sake of promoting the impersonal good. I develop the complementary objection that act-consequentialism is underdemanding: it fails to acknowledge that agents have moral reasons to bear certain costs themselves, even when it would be impersonally better for others to bear these costs.

What should we make of claims by members of other groups to have moralities different from our own? Human Rights in Chinese Thought gives an extended answer to this question in the first study of its kind. It integrates a full account of the development of Chinese rights discourse - reaching back to important, though neglected, origins of that discourse in 17th and 18th century Confucianism - with philosophical consideration of how various communities should respond to contemporary Chinese claims about (...) the uniqueness of their human rights concepts. The book elaborates a plausible kind of moral pluralism and demonstrates that Chinese ideas of human rights do indeed have distinctive characteristics, but it nonetheless argues for the importance and promise of cross-cultural moral engagement.

You ought to save a larger group of people rather than a distinct smaller group of people, all else equal. A consequentialist may say that you ought to do so because this produces the most good.

Secondly, you are rationally required to achieve as many of these ends as possible, if you have these ends. (shrink)

This article diagnoses the problem of plagiarism in academic books and articles in the disciplines of philosophy and theology. It identifies three impediments to institutional reform. They are: (1) a misplaced desire to preserve personal and institutional reputations; (2) a failure to recognize that attribution in academic writing admits of degrees; and (3) a disproportionate emphasis on the socalled “intention to plagiarize.” A detailed case study provides an illustration of the need for institutional reform in the post-publication processes in the (...) disciplines of philosophy and theology.

The relation between body and mind is one of the oldest riddles that has puzzled mankind. That material and mental events may interact is accepted even by the law: our mental capacity to concentrate on the task can be seriously reduced by drugs. Physical and chemical processes may act upon the mind; and when we are writing a difficult letter, our mind acts upon our body and, through a chain of physical events, upon the mind of the recipient of the (...) letter. This is what the authors of this book call the 'interaction of mental and physical events'. We know very little about this interaction; and according to recent philosophical fashions this is explained by the alleged fact that we have brains but no thoughts. The authors of this book stress that they cannot solve the body mind problem; but they hope that they have been able to shed new light on it. Eccles especially with his theory that the brain is a detector and amplifier; a theory that has given rise to important new developments, including new and exciting experiments; and Popper with his highly controversial theory of 'World 3'. They show that certain fashionable solutions which have been offered fail to understand the seriousness of the problems of the emergence of life, or consciousness and of the creativity of our minds. In Part I, Popper discusses the philosophical issue between dualist or even pluralist interaction on the one side, and materialism and parallelism on the other. There is also a historical review of these issues. In Part II, Eccles examines the mind from the neurological standpoint: the structure of the brain and its functional performance under normal as well as abnormal circumstances. The result is a radical and intriguing hypothesis on the interaction between mental events and detailed neurological occurrences in the cerebral cortex. Part III, based on twelve recorded conversations, reflects the exciting exchange between the authors as they attempt to come to terms with their opinions. (shrink)

In general, epistemic internalists hold that an individual’s justification for a belief is exhausted by her reflectively accessible reasons for thinking that the contents of her beliefs are true. Applying this to the epistemology of testimony, a hearer’s justification for beliefs acquired through testimony is exhausted by her reflectively accessible reasons to think that the contents of the speaker’s testimony is true. A consequence of internalism is that subjects that are alike with respect to their reflectively accessible reasons are alike (...) with respect to what they have justification to believe. Testimony should be thought no different: hearers that are alike with respect to reflectively accessible reasons to think that a speaker’s testimony is true are alike with respect to their justification for beliefs based upon that testimony. But it has been recently argued that this view faces powerful counterexamples. So the central question is this: assuming that a hearer can acquire justification to believe a proposition through the testimony of a speaker, can epistemic internalism provide the resources to explain how such justification is possible? My aim in this paper is to address these counterexamples, and in so doing, defend epistemic internalist accounts of testimony. (shrink)

Transdisciplinary research knits together knowledge from diverse epistemic communities in addressing social-environmental challenges, such as biodiversity loss, climate crises, food insecurity, and public health.

We offer a critical assessment of demarcationist approaches in philosophy of science and outline a constructive alternative of transdisciplinary philosophy of science. While a demarcationist focus obscures the complex relations between epistemic communities, transdisciplinary (...) philosophy of science provides resources for meeting epistemic and political challenges of collaborative knowledge production.

Epistemic Authority is a mature work of a leading epistemologist and philosopher of religion. It is a work primarily in epistemology with applications to religious epistemology. There are obvious applications of the notion of epistemic authority to philosophy of religion. For, on the face of it, the notion of some kind of ”epistemic authority’ may serve as a conceptual anchor for our understanding of faith. Indeed, there is ample historical precedent for this. Faith, says Locke, is ”the assent to any (...) proposition... upon the credit of the proposer, as coming from God, in some extraordinary way of communication’. 1 In later Lockeans, ”credit’ is often rendered ”authority’, and the terms were used synonymously at the time of his writing. 2 One of the beauties of Locke’s view is its reductionism, that is, it’s parsimony, which is a species of elegance and therefore beauty. Zagzebski’s notion is more high-octane than Locke’s. In this essay I will do four things. In Section 1 I will describe two kinds or notions of authority or at least two usages of the word ”authority’. In Section 2 I will describe Zagzebski’s use of one of these notions, the non-Lockean one, to ground the reasonableness of religious belief. In Section 3 I will give four arguments against her view. In section 4 I will reply to her critique of Locke. The upshot, in my view, is that though we learn much from Epistemic Authority, a more Lockean approach to the nature of faith is still preferable.

In the four sections that follow, I respond to the objections.

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

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