Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

The Planteome project provides a suite of reference and species-specific ontologies for plants and annotations to genes and phenotypes. Ontologies serve as common standards for semantic integration of a large and growing corpus of plant genomics, phenomics and genetics data. The reference ontologies include the Plant Ontology, Plant Trait Ontology, and the Plant Experimental Conditions Ontology developed by the Planteome project, along with the Gene Ontology, Chemical Entities of Biological Interest, Phenotype and Attribute Ontology, and others. The project also provides (...) access to species-specific Crop Ontologies developed by various plant breeding and research communities from around the world. We provide integrated data on plant traits, phenotypes, and gene function and expression from 95 plant taxa, annotated with reference ontology terms. (shrink)

The conditions of hunting and gathering through which one line of primates evolved into humans form the basis of what I term the wild self, a self marked by developmental needs of prolonged human neoteny and by deep attunement to the profusion of communicative signs of instinctive intelligence in which relatively “unmatured” hominids found themselves immersed. The passionate attunement to, and inquiry into, earth-drama, in tracking, hunting, foraging, rhythming, singing, and other arts/sciences, provided the trail to becoming human, and provide (...) external grammatical structures that became the basis of human language and animate mind. I outline my new philosophy of history as a progress in precision, counteracted by a regressive contraction of mind. The progress associated with history since the beginning of agriculturally-based civilizations can be considered as a regressive contraction from animate mind of our hunter-gatherer evolutionary past, to anthropocentric mind, and finally to the ghost in the machine world-view of mechanico-centric mind. Contemporary consumption culture represents an inversion of the original conditions of the human self, and indeed, targets aspects of developmental neoteny to condition conformity to its rational-mechanical system imperatives.

Plato’s Laws include what H.L.A. Hart called the ‘classical thesis’ about the nature and role of law: the law exists to see that one leads a morally good life. This paper develops Hart’s brief remarks by providing a panorama of the classical thesis in Laws. This is done by considering two themes: (1) the extent to which Laws is paternalistic, and (2) the extent to which Laws is naturalistic. These themes are significant for a number of reasons, including because they (...) show how Laws might be viewed as a sophisticated forerunner of natural law theory. The upshot is that Plato's metaphysical commitments about legal ontology allow him to base the truth of legal propositions on the way they relate to the truth of corresponding moral propositions.

Thus far most of the scholarship on the axial age has followed Karl Jaspers’ denial that nature could be a significant source and continuing influence in the historical development of human consciousness. Yet more than a half century before Jaspers, the originator of the first nuanced theory of what Jaspers termed the axial age, John Stuart-Glennie, mapped out a contrasting philosophy of history that allowed a central role to nature in historical human development. This essay concerns issues related to my (...) book, From the Axial Age to the Moral Revolution, and begins with a discussion of how I came to uncover the forgotten work of John Stuart-Glennie. Although Jaspers and Stuart-Glennie each drew similar conclusions regarding many of the facts of the moral revolution respectively the Axial Age, there are significant differences in their philosophies of history, concerning, for example the problem, whether history can be regarded deterministically or as an open whole, and whether nature can be a source of profound spiritual significance and even transcendence or whether that realm is limited to historical consciousness. I also briefly discuss two other overlooked contributors, namely D. H. Lawrence, who wrote on the phenomena twenty years before Jaspers, and Lewis Mumford, who is one of the first writers to draw from Jaspers' work. I then respond to four diverse scholarly essays on my book, delineating in the process my own philosophy of history as a progress in precision, paradoxically counteracted by a regressive contraction of mind.

The revolutionary outbreak in a variety of civilizations centered around 600 B.C.E., a period in which the great world religions as well as philosophy emerged, from Hebrew scriptures and the teachings of Buddha to the works of Greek and Chinese philosophers, has been named the Axial Age by Karl Jaspers. Yet 75 years earlier, in 1873, unknown to Jaspers and still unknown to the world, John Stuart Stuart-Glennie elaborated a fully developed and more nuanced theory of what he termed The (...) Moral Revolution to characterize the period. This book also brings to light the previously undiscussed ideas of D. H. Lawrence on the phenomenon from 20 years before Jaspers, the seldom mentioned contributions of Lewis Mumford, and proposes a new context for understanding the phenomenon. Halton rewrites the history of this fascinating theory and opens new ways of conceiving the meaning of The Moral Revolution for today. (shrink)

[Accepted for publication in Lakatos's Undone Work: The Practical Turn and the Division of Philosophy of Mathematics and Philosophy of Science, special issue of Kriterion: Journal of Philosophy. Edited by S. Nagler, H. Pilin, and D. Sarikaya.] Lakatos’s analysis of progress and degeneration in the Methodology of Scientific Research Programmes is well-known. Less known, however, are his thoughts on degeneration in Proofs and Refutations. I propose and motivate two new criteria for degeneration based on the discussion in Proofs and Refutations (...) – superfluity and authoritarianism. I show how these criteria augment the account in Methodology of Scientific Research Programmes, providing a generalized Lakatosian account of progress and degeneration. I then apply this generalized account to a key transition point in the history of entropy – the transition to an information-theoretic interpretation of entropy – by assessing Jaynes’s 1957 paper on information theory and statistical mechanics.

History can be understood as involving a problematic interplay between the long-term legacy of human evolution, still tempered into the human body today, and the shorter-term heritage of civilization from its beginnings to the present. Each of us lives in a tension between our indigenous bodies and our civilized selves, between the philosophy of the earth and that which I characterize as “the philosophy of escape from the earth.” The standard story of civilization is one of linear upward progress, a (...) story that I contest with an alternative philosophy of history, picturing history instead as a set of concentric circles. I have devised a new philosophy of history with a three-part approach to understanding human development, taking civilization not as a linear advance of progress, but rather as a progress in precision, paradoxically counteracted by a regression in mind: history as a contraction of mind. I describe three stages in the contraction of mind: 1) animate mind as the evolved outlook of foraging life; 2) anthropocentric mind as representing the contracting transformation of consciousness produced by agriculturally-based civilization; 3) mechanico-centric mind as representing a further contraction from human-centered to a machine-centered consciousness, produced by the rise of modern civilization and the mechanical scientific worldview. Hence, this progressive contraction is marked by a turn from original practical and reverential attunement to the living earth in hunting and gathering societies, or animate mind, to a narrower focus of anthropocentric mind beginning with the development of early civilizations, where the human element became central and the wild devalued. And it moves to an even more narrow focus of mechanico-centric mind, expanding out of late medieval Europe and the development of modern science, where the machine became model of the ultimate, the objectivist filter through which the world is to be understood and made to fit. Far from controlling nature, humans have been consuming it in an unsustainable Malthusian-like trajectory whose limits are being reached in our time. (shrink)

The great divide of modern thought is whether mind is real or naught. The conceit that either mind is reducible to matter or that mind is utterly ethereal is rooted in a mind-versus-matter dichotomy that can be characterized as the modern error, a fatally flawed fallacy rooted in the philosophy and culture of nominalism. A Peircean semiotic outlook, applied to an understanding of social life, provides a new and full-bodied understanding of semiosis as the bridge between mind and matter, and (...) human biology and culture. I begin by first delineating the false divide and showing Charles Sanders Peirce’s alternative to it, then explore the implications of a semiotic approach to mind as trans-action, then consider the self-transcending nature of the human body-mind. Finally I outline my ecological, biosemiotic account of mind, which reveals that, indeed, mind matters, and in ways that unexpect-edly resemble the forms of animism that characterized the hunting-gathering foragers through whom we anatomically modern humans emerged.

The rise and legacy of world religions out of that period centered roughly around 500-600 BCE, what John Stuart-Glennie termed in 1873 the moral revolution, and Karl Jaspers later, in 1949, called the axial age, has been marked by heightened ideas of transcendence. Yet ironically, the world itself, in the literal sense of the actual earth, took on a diminished role as a central element of religious sensibility in the world religions, particularly in the Abrahamic religions. Given the issue today (...) of ecological unsustainability, including massive die-offs of wildlife and ever-increasing global human population and consumption, the legacy of those world religions face the question I consider here: Can religion transcend the earth in the long run? With the Axial Age/Moral Revolution, comes the possibility of transcendence of the world per se. The moral revolution/Axial Age represented significant changes in civilization, to be sure, but it can also be taken, as I do, as a second phase in the radical shift to anthropocentric mind already begun with the advent of agriculturally based civilization. The axial ideal of transcendence connects to a larger ideal, manifest not only in the legacies of the world religions but in contemporary science and technology, of a philosophy of escape from the earth. I show how ideas of axial transcendence, celebrated by scholars such as Jaspers and Bellah, nevertheless involve an unacknowledged tragic cost, the forgetting of the earth and its lessons and limits as central to what I have termed elsewhere, “sustainable wisdom.” .

Harms of medical interventions are systematically underestimated in clinical research. Numerous factors—conceptual, methodological, and social—contribute to this underestimation. I articulate the depth of such underestimation by describing these factors at the various stages of clinical research. Before any evidence is gathered, the ways harms are operationalized in clinical research contributes to their underestimation. Medical interventions are first tested in phase 1 ‘first in human’ trials, but evidence from these trials is rarely published, despite the fact that such trials provide the (...) foundation for assessing the harm profile of medical interventions. If a medical intervention is deemed safe in a phase 1 trial, it is tested in larger phase 2 and 3 clinical trials. One way to think about the problem of underestimating harms is in terms of the statistical ‘power’ of a clinical trial—the ability of a trial to detect a difference of a certain effect size between the experimental group and the control group. Power is normally thought to be pertinent to detecting benefits of medical interventions. It is important, though, to distinguish between the ability of a trial to detect benefits and the ability of a trial to detect harms. I refer to the former as power-B and the latter as power-H. I identify several factors that maximize power-B by sacrificing powerH in phase 3 clinical trials. If a medical intervention is approved for general use, it is evaluated by phase 4 post-market surveillance. Phase 4 surveillance of harms further contributes to underestimating the harm profile of medical interventions. At every stage of clinical research the hunt for harms is shrouded in secrecy, which further contributes to the underestimation of the harm profiles of medical interventions. (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)

In today’s neoliberal audit cultures university rankings, quantitative evaluation of publications by JIF or researchers by h-index are believed to be indispensable instruments for “quality assurance” in the sciences. Yet there is increasing resistance against “impactitis” and “evaluitis”.

Analysing the “Joshua Lederberg Papers” I want to illuminate eventually successful ‘invention’ (...) of science citation indexing is a product of contingent factors. To overcome severe resistance Eugene Garfield, the “father” of citation indexing, had to foster overoptimistic attitudes and to downplay the severe problems connected to global and multidisciplinary citation indexing. The difficulties to handle different formats of references and footnotes, non-Anglo-American names, and of publications in non-English languages were known to the pioneers of citation indexing. Nowadays the huge for-profit North-American media corporation Thomson Reuters is the owner of the citation databases founded by Garfield. Thomson Reuters’ influence on funding decisions, individual careers, departments, universities, disciplines and countries is immense and ambivalent. Huge technological systems show a heavy inertness. This insight of technology studies is applicable to the large citation indexes by Thomson Reuters, too. (shrink)

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

The Louvre Museum is the largest of the world's art museums by its exhibition surface. These represent the Western art of the Middle Ages in 1848, those of the ancient civilizations that preceded and influenced it (Oriental, Egyptian, Greek, Etruscan and Roman), and the arts of early Christians and Islam. At the origin of the Louvre existed a castle, built by King Philip Augustus in 1190, and occupying the southwest quarter of the current Cour Carrée. In 1594, Henri IV decided (...) to unite the palace of the Louvre with the palace of the Tuileries built by Catherine de Medicis. The Cour Carrée was built by the architects Lemercier and then Le Vau, under the reign of Louis XIII and Louis XIV. The Department of Paintings currently has about 7,500 paintings (of which 3,400 are exposed), covering a period that goes from the Middle Ages to 1848 (date of the beginning of the Second Republic). By including the deposits, the collection is, with 12,660 works, the largest collection of ancient paintings in the world. With rare exceptions, the works after 1848 were transferred to the Musée d'Orsay when it was created in 1986.

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.

Frankfurt cases are purported counterexamples to the Principle of Alternative Possibilities, which implies that we are not morally responsible for unavoidable actions. A major permutation of the counterexample strategy features buffered alternatives; this permutation is designed to overcome an influential defense of the Principle of Alternative Possibilities. Here we defend the buffering strategy against two recent objections, both of which stress the timing of an agent’s decision. We argue that attributions of moral responsibility aren’t time-sensitive in the way the objectors (...) suppose. We then turn to the crucial question of when an action is relevantly avoidable—when, in the parlance of the literature, an alternative possibility is robust. We call attention to two plausible tests for robustness that merit further consideration, showing that the agents in buffered Frankfurt cases don’t pass these tests, despite being morally responsible for their actions.

Accounts of scientific explanation disagree about what’s required for a cause, law, or other fact to be a reason why an event occurs. In short, they disagree about the conditions for explanatory relevance. Nonetheless, most accounts presuppose that claims about explanatory relevance play a descriptive role in tracking reality. By rejecting the need for this descriptivist assumption, I develop an expressivist account of explanatory relevance and explanation: to judge that an answer is explanatory is to express an attitude of _being (...) for being satisfied by that answer_. I show how expressivism vindicates ordinary scientific discourse about explanation, including claims about the objectivity and mind-independence of explanations. By avoiding commitment to ontic relevance relations, I rehabilitate an irrealist conception of explanation. (shrink)

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.

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)

The paper investigates whether imaginative states about propositions can be assessed in terms of fittingness (also known as correctness, appropriateness, aptness). After characterizing propositional imaginings and explaining the idea of fittingness, I present some considerations in favour of the no conditions view: imagining seems to be the sort of action that cannot be done unfittingly, and imaginings have no external cognitive nor conative goals in light of which they could be unfitting. I then examine the local conditions view, that there (...) can be fittingness conditions on imaginings, but that these are inherited from the mental projects in which imaginings can play a role. Given that there are virtues of the imagination such as creativity and spontaneity, and given that imaginings are subject to purposive mechanisms, and given that there are cases in which it is unfitting to fail to imagine, I endorse the general conditions view, on which imaginings have a goal, and therefore fittingness conditions, even outside the context of mental projects. I then examine 4 versions of the general conditions view and argue that imaginings aim to make contents available to mental projects. (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)

The principle of alternate possibilities (PAP), making the ability to do otherwise a necessary condition for moral responsibility, is supposed by Harry Frankfurt, John Fischer, and others to succumb to a peculiar kind of counterexample. The paper reviews the main problems with the counterexample that have surfaced over the years, and shows how most can be addressed within the terms of the current debate. But one problem seems ineliminable: because Frankfurt''s example relies on a counterfactual intervener to preclude alternatives to (...) the person''s action, it is not possible for it to preclude all alternatives (intervention that is contingent upon a trigger cannot bring it about that the trigger never occurred). This makes it possible for the determined PAPist to maintain that some pre-intervention deviation is always available to ground moral responsibility. In reply, the critic of PAP can examine all the candidate deviations and argue their irrelevance to moral responsibility (a daunting prospect); or the critic can dispense with counterfactual intervention altogether. The paper pursues the second of these strategies, developing three examples of noncounterfactual intervention in which (i) the agent has no alternatives (and a fortiori no morally relevant alternatives), yet (ii) there is just as much reason to think that the agent is morally responsible as there was in Frankfurt''s original example. The new counterexamples do suffer from one liability, but this is insufficient in the end to repair PAP''s conceptual connection between moral responsibility and alternate possibilities. (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)

Short online essay on the state of policing in liberal societies, discussing how executive discretionary power has grown to such a degree that it has trended toward illiberal practices and policies.

Science frequently gives us multiple, compatible ways of solving the same problem or formulating the same theory. These compatible formulations change our understanding of the world, despite providing the same explanations. According to what I call "conceptualism," reformulations change our understanding by clarifying the epistemic structure of theories. I illustrate conceptualism by analyzing a typical example of symmetry-based reformulation in chemical physics. This case study poses a problem for "explanationism," the rival thesis that differences in understanding require ontic explanatory differences. (...) To defend conceptualism, I consider how prominent accounts of explanation might accommodate this case study. I argue that either they do not succeed, or they generate a skeptical challenge. (shrink)

ABSTRACT Co-parents who differ in their ideal child rearing policies should compromise, argues Marcus William Hunt. Josh Milburn and Carlo Alvaro dispute this when it comes to veganism. Milburn argues that veganism is a matter of justice and that to compromise over justice is (typically) impermissible. I suggest that compromise over justice is often permissible, and that compromise over justice may be required by justice itself. Alvaro offers aesthetic, gustatory, and virtue-based arguments for ethical veganism, showing that veganism involves (...) sensibilities and virtues, and argues that veganism involves a belief. Alvaro takes this to show that parental compromise is impermissible. I suggest that Alvaro’s arguments are implausible and that the shaping of a child’s sensibilities and virtues is an apt matter for parental compromise. (shrink)

I claim that there is pro tanto moral reason for parents to not raise their child on a vegan diet because a vegan diet bears a risk of harm to both the physical and the social well-being of children. After giving the empirical evidence from nutrition science and sociology that supports this claim, I turn to the question of how vegan parents should take this moral reason into account. Since many different moral frameworks have been used to argue for veganism, (...) this is a complex question. I suggest that, on some of these moral frameworks, the moral reason that some parents have for not raising their child on a vegan diet on account of this risk is plausibly as strong as the reason they have for raising their child on a vegan diet. In other words, the moral reason I outline is weighty enough to justify some vegan parents in plausibly finding it permissible to not raise their child on a vegan diet. (shrink)

Prima facie, rule-consequentialism as a moral theory would correlate with the concerns of an omnibenevolent being should one exist. Indeed, such a being would be divine, and under the lenses of the three Abrahamic religions, would inter alia, also be omnipotent and omniscient. In this paper, I consider the attitude of such a being to rule-consequentialism in human society. I argue, from a probabilistic perspective, that the evidence of Abrahamic scripture confirms, to a degree, that God would judge rule-consequentialism to (...) be a sound moral theory in different societies. I also consider a similar argument from a secular perspective. (shrink)

The use of deception and dishonesty is widely accepted as a fact of life in policing. This paper thus defends a counterintuitive claim: Good faith is a normative foundation for the police as a political institution. Good faith is a core value of contracts, and policing is contractual in nature both broadly (as a matter of social contract theory) and narrowly (in regard to concrete encounters between law enforcement officers and the public). Given the centrality of good faith to policing, (...) dishonesty and deception on par with fraud are justified only as a narrowly circumscribed investigative tool that is constrained by institutional commitments to the fair distribution of security and the rule of law. The practical upshot is the preclusion of most dishonest and deceptive police tactics on par with fraud, leading to an institution that is less proactive and more reactive. (shrink)

A summary of common arguments for belief in God - teleological, cosmological, ontological, and reformed epistemology.

Why does institutional police brutality continue so brazenly? Criminologists and other social scientists typically theorize about the causes of such violence, but less attention is given to normative questions regarding the demands of justice. Some philosophers have taken a teleological approach, arguing that social institutions such as the police exist to realize collective ends and goods based upon the idea of collective moral responsibility. Others have approached normative questions in policing from a more explicit social-contract perspective, suggesting that legitimacy is (...) derived by adhering to (limited) authority. This article examines methodologies within political philosophy for analyzing police injustice. The methodological inquiry leads to an account of how justice constrains the police through both special (or positional) moral requirements that officers assume voluntarily, as well as general moral requirements in virtue of a polity’s commitment to moral, political and legal values beyond law enforcement and crime reduction. The upshot is a conception of a police role that is constrained by justice from multiple foundational stances. (shrink)

This is a contribution to an Author Meets Critics special issue on John Martin Fischer's _Our Fate: Essays on God and Free Will_.

The paper argues that ‘All varieties of gratitude are only overall fitting when targeted towards agents,’ for instance that any variety of gratitude for the beautiful sunset is only overall fitting if a supernatural agent such as God exists. The first premise is that ‘Prepositional gratitude is overall fitting only when targeted towards agents.’ For this premise, intuitive judgments are offered. The second premise is that ‘Prepositional gratitude is the paradigmatic variety of gratitude.’ For this premise, an aspect of the (...) common consent of philosophers about gratitude is noted and the metaphysical basicness of prepositional gratitude is argued for. This gives the intermediate conclusion that ‘The paradigmatic variety of gratitude is overall fitting only when targeted towards agents.’ The fourth premise is that ‘If the paradigmatic variety of gratitude is overall fitting only when targeted towards agents, then all varieties of gratitude are overall fitting only when targeted towards agents.’ To supply the conditional of this premise, the Paradigmatic Fittingness Principle is offered, which states that ‘Paradigmatic emotions set the fittingness conditions for their non-paradigmatic varieties.’ This principle is argued for by noting that it vindicates some popular and plausible intuitive judgements and gives an error theory of why one might think that gratitude could be fittingly targeted towards non-agents, and by suggesting the absence of any other plausible source of fittingness conditions for non-paradigmatic emotions.

Reformulating a scientific theory often leads to a significantly different way of understanding the world. Nevertheless, accounts of both theoretical equivalence and scientific understanding have neglected this important aspect of scientific theorizing. This essay provides a positive account of how reformulation changes our understanding. My account simultaneously addresses a serious challenge facing existing accounts of scientific understanding. These accounts have failed to characterize understanding in a way that goes beyond the epistemology of scientific explanation. By focusing on cases in which (...) we have differences in understanding without differences in explanation, I show that understanding does not reduce to explanation. (shrink)

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)

Policing in many parts of the world—the United States in particular—has embraced an archetypal model: a conception of the police based on the tenets of individuated archetypes, such as the heroic police “warrior” or “guardian.” Such policing has in part motivated moves to (1) a reallocative model: reallocating societal resources such that the police are no longer needed in society (defunding and abolishing) because reform strategies cannot fix the way societal problems become manifest in (archetypal) policing; and (2) an algorithmic (...) model: subsuming policing into technocratic judgements encoded in algorithms through strategies such as predictive policing (mitigating archetypal bias). This paper begins by considering the normative basis of the relationship between political community and policing. It then examines the justification of reallocative and algorithmic models in light of the relationship between political community and police. Given commitments to the depth and distribution of security—and proscriptions against dehumanizing strategies—the paper concludes that a nonideal-theory priority rule promoting respect for personhood (manifest in community and dignity-promoting policing strategies) is a necessary condition for the justification of the above models.

This book provides a comprehensive examination of the police role from within a broader philosophical context. Contending that the police are in the midst of an identity crisis that exacerbates unjustified law enforcement tactics, Luke William Hunt examines various major conceptions of the police—those seeing them as heroes, warriors, and guardians. The book looks at the police role considering the overarching societal goal of justice and seeks to present a synthetic theory that draws upon history, law, society, psychology, and (...) philosophy. Each major conception of the police role is examined in light of how it affects the pursuit of justice, and how it may be contrary to seeking justice holistically and collectively. The book sets forth a conception of the police role that is consistent with the basic values of a constitutional democracy in the liberal tradition. Hunt’s intent is that clarifying the police role will likewise elucidate any constraints upon policing strategies, including algorithmic strategies such as predictive policing. This book is essential reading for thoughtful policing and legal scholars as well as those interested in political philosophy, political theory, psychology, and related areas. Now more than ever, the nature of the police role is a philosophical topic that is relevant not just to police officials and social scientists, but to everyone. (shrink)

The paper begins with a description of a grey seal performing conspecific infanticide. The paper then gives an account of “nobleness” and “brutishness.” Roughly, a behavioural-disposition is noble/brutish if it is one that would be a moral virtue/vice if the possessor of the behavioural-disposition were a moral agent. The paper then advances two pairs of axiological claims. The first pair of claims is that nobleness is good and that brutishness is bad. The second pair of claims is about an axiological (...) interaction between nobleness/brutishness and well-being. That any non-human animal lacks well-being is bad. Yet, it is worse that a noble non-human animal lacks well-being, and not so bad that a brutish non-human animal lacks well-being. Lastly, the paper discusses some potential moral implications of these axiological claims, for instance that factory farming is especially wrong because it causes noble non-human animals to lack well-being.

There is a growing sense that many liberal states are in the midst of a shift in legal and political norms—a shift that is happening slowly and for a variety of reasons relating to security. The internet and tech booms—paving the way for new forms of electronic surveillance—predated the 9/11 attacks by several years, while the police’s vast use of secret informants and deceptive operations began well before that. On the other hand, the recent uptick in reactionary movements—movements in which (...) the rule of law seems expendable—began many years after 9/11 and continues to this day. One way to describe this book is an examination of the moral limits on modern police practices that flow from the basic legal and political tenets of the liberal tradition. The central argument is that policing in liberal states is constrained by a liberal conception of persons coupled with particular rule of law principles. Part I consists of three chapters that constitute the book’s theoretical foundation, including an overview of the police’s law enforcement role in the liberal polity and a methodology for evaluating that role. Part II consists of three chapters that address applications of the theory, including the police’s use of informants, deceptive operations, and surveillance. The upshot is that policing in liberal societies has become illiberal in light of its response to both internal and external threats to security. The book provides an account of what it might mean to retrieve policing that is consistent with the basic tenets of liberalism and the limits imposed by those tenets. [This is an uncorrected draft of the book's preface and introduction, forthcoming from Oxford University Press.]. (shrink)

The paper offers a three-premise argument that a person with first-hand experience of possession and exorcism, such as an exorcist, can have a justified belief in the existence of demons. (1) “Exorcism involves a process by which the exorcist comes to believe that testimony is offered by a demon.” Cited for (1) are the Gospels, the Roman Ritual, some modern cases of exorcism, and exorcism practices in non-Christian contexts. (2) “If defeaters are absent, the exorcist may treat as reliable the (...) process by which he comes to believe that testimony is offered by a demon.” For (2) a case is offered that we have a reliable ability to identify when testimony is being offered and when it is being offered by particular types of agents, what is termed testifier-identification. (3) “In many cases of exorcism, defeaters are absent.” An inductive case is given for (3) by responding to possible defeaters, including several suggested recently by David Kyle Johnson. Therefore, in many cases of exorcism the exorcist may treat as reliable the processes by which he comes to believe that testimony is offered by a demon, and so can have a justified belief in the existence of demons.

I distinguish between a _metaphysical_ problem generated by the argument for theological fatalism, and a _theological_ problem posed by the argument. Some responses to the argument, including ones associated with Boethius, Aquinas and Ockham, address only the theological problem. Even if such responses succeed in showing that God's foreknowledge doesn't threaten human freedom, they fail to take the full measure of the argument for theological fatalism, since the metaphysical problem remains to be solved.

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.

The paper that follows continues a discussion with Tomis Kapitan in the pages of this journal over the compatibility of divine agency with divine foreknowledge. I had earlier argued against two premises in Kapitan's case for omniscient impotence: (i) that intentionally A-ing presupposes prior acquisition of the intention to A, and (ii) that acquiring the intention to A presupposes prior ignorance whether one will A. In response to my criticisms, Kapitan has recently offered new defences for these two premises. I (...) show in reply why neither defence succeeds in rehabilitating the case against omniscient agency. (Note that the very first sentence of the published version has a misprint: instead of "To claim that divine foreknowledge is inconsistent with divine agency has been pressed with increasing frequency of late . . .", it should read, "_The_ claim . . ."!).
