Panni les aspects remarquables de l'Aristarque (1644) de Roberval, on relève la répétition fréquente dans le texte de l'abréviation« P.N.E.M.». Ces lettres signifient « pondere, numero et mensura ». Ces mots sont tirés du Livre de la Sagesse, XI, 20: « Pondere, mensura, numero Deus omnia fecit » (Vulgate). Ce verset est cité chez beaucoup d'auteurs qui veulent louer Dieu Géomètre. Cependant, Roberval n'est nullement pieux. Il s'agit donc ici de savoir pourquoi il se sert de « P.N.E.M.» dans son (...) texte. Roberval se montre-t-il ainsi solidaire de ses confrères mathématiciens du Collège royal, dont le verset serait la devise? (shrink)

Discrepancies between the Uniform Determination of Death Act (UDDA) and the adult and pediatric diagnostic guidelines for brain death (BD) (the “Guidelines”) have motivated proposals to revise the UDDA. A revision proposed by Lewis, Bonnie and Pope (the RUDDA), has received particular attention, the three novelties of which would be: (1) to specify the Guidelines as the legally recognized “medical standard,” (2) to exclude hypothalamic function from the category of “brain function,” and (3) to authorize physicians to conduct an apnea (...) test without consent and even over a proxy’s objection. One hundred seven experts in medicine, bioethics, philosophy, and law, spanning a wide variety of perspectives, have come together in agreement that while the UDDA needs revision, the RUDDA is not the way to do it. Specifically, (1) the Guidelines have a non-negligible risk of false-positive error, (2) hypothalamic function is more relevant to the organism as a whole than any brainstem reflex, and (3) the apnea test carries a risk of precipitating BD in a non-BD patient, provides no benefit to the patient, does not reliably accomplish its intended purpose, and is not even absolutely necessary for diagnosing BD according to the internal logic of the Guidelines; it should at the very least require informed consent, as do many procedures that are much more beneficial and less risky. Finally, objections to a neurologic criterion of death are not based only on religious belief or ignorance. People have a right to not have a concept of death that experts vigorously debate imposed upon them against their judgment and conscience; any revision of the UDDA should therefore contain an opt-out clause for those who accept only a circulatory-respiratory criterion.

The mainstream rationale for equating brain death (BD) with death is that the brain confers integrative unity upon the body, transforming it from a mere collection of organs and tissues to an organism as a whole. In support of this conclusion, the impressive list of the brains myriad integrative functions is often cited. Upon closer examination, and after operational definition of terms, however, one discovers that most integrative functions of the brain are actually not somatically integrating, and, conversely, most integrative (...) functions of the body are not brain-mediated. With respect to organism-level vitality, the brains role is more modulatory than constitutive, enhancing the quality and survival potential of a presupposedly living organism. Integrative unity of a complex organism is an inherently nonlocalizable, holistic feature involving the mutual interaction among all the parts, not a top-down coordination imposed by one part upon a passive multiplicity of other parts. Loss of somatic integrative unity is not a physiologically tenable rationale for equating BD with death of the organism as a whole. (shrink)

At its inception, “brain death” was proposed not as a coherent concept but as a useful one. The 1968 Ad Hoc Committee of the Harvard Medical School to Examine the Definition of Brain Death gave no reason that “irreversible coma” should be death itself, but simply asserted that the time had come for it to be declared so. Subsequent writings by chairman Henry Beecher made clear that, to him at least, death was essentially a social construct, and society could define (...) it however it pleased. The first widely endorsed attempt at a philosophical justification appeared thirteen years later, with a report from the President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research and a seminal paper by James Bernat, Charles Culver, and Bernard Gert, which introduced the insightful tripartite scheme of concept, criterion, and tests for death. Their paper proposed that the correct concept of death is the “permanent cessation of functioning of the organism as a whole,” which tenuously remains the mainstream concept to this day. In this essay, I focus on this mainstream concept, arguing that equating brain death with death involves several levels of incoherence: between concept and criterion, between criterion and tests, between tests and concept, and between all of these and actual brain death praxis.

From the start, I followed the case of Jahi McMath with great interest. In December 2013, she clearly fulfilled the diagnostic criteria for brain death. As a neurologist with a special interest in chronic brain death, I was not surprised that, after she was flown to New Jersey, where she became statutorily resurrected and was treated as a comatose patient, Jahi's condition quickly improved. In 2014, her family reported that she sometimes responded to simple motor commands. I shared the general (...) skepticism regarding these reports, assuming that the family was in denial and was misinterpreting spinal myoclonus (a rapid, involuntary twitch generated by the spinal cord) as volitional. The family had noticed that when Jahi's heart rate was above eighty beats per minute, she was more likely to respond, as though the heart rate reflected some sort of inner level of arousal. So they began to make video recordings. I have been privileged to be entrusted with copies of these recordings, forty‐eight of which proved suitable for assessing alleged responsiveness. All have been certified by a forensic video expert as unaltered. The first thing that struck me was that the great majority of the alleged responses were not spinal myoclonus. In fact, they did not resemble any type of spontaneous, involuntary movement described in patients paralyzed from high spinal cord lesions. (shrink)

: American society traditionally has assumed a univocal notion of "death," largely because we have only one word for it and, until recently, have not needed a more nuanced notion. The reality of death-processes does not preclude the reality of death events. Linguistically, "death" can be understood only as an event; there are other words for the process. Our death vocabulary should expand to reflect multiple events along the process from sickness to decomposition. Depending on context, some death-related events may (...) constitute a more obvious discontinuity than others and more justifiably may be considered "death" within that context. There is no reason to assume a priori that there must be an overarching, unitary concept of death from which all diagnostic criteria must derive. Regarding organ transplantation, the relevant question is not "Is the patient dead?" but rather "Can organs X, Y, Z . . . be removed without causing or hastening death or harming the patient?".

The chapter emphasizes the complexity of the relations between philosophy and science in the eighteenth century, as they must be seen against the background that, in the early modern period, as in the preceding centuries, philosophy generally included physics or natural philosophy, mathematics, and metaphysics. Showing the variance in attitudes among Leibniz, Newton, and Locke on how to draw a line of division between metaphysics and physics with regard to a sample of topics, this chapter draws attention to the divergent (...) starting points of British and German metaphysical conceptions in the course of the eighteenth century. Tracing a trajectory of such conceptions in Britain – Berkeley, Hume, Cullen – and contrasting it with the position of Kant in Germany, this essay records the trembling or perhaps even crumbling of metaphysics caused by the growing tensions between metaphysics/philosophy and natural philosophy/science. In the end, this state of affairs led to a remarkably indifferent attitude toward metaphysics (Cullen) and, alternatively, to a radical critique of its epistemological foundations (Kant). (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Melon and the Dictionary:Reflections on Descartes's DreamsAlan Gabbey and Robert E. HallThe interpretation of dreams is rarely answerable to either evidential or settled theoretical control. When the phantasms of the dreaming mind seem unaccountable, as they often do, they seem to belong to a mental world beyond the reach of historical, philosophical, or scientific analysis, a world for which the rules of methodological engagement seem inappropriate, rather (...) than merely impossible to observe. So in advance we ask the reader's indulgence if we appear somewhat to ignore the historian's normal duty to transmute favored speculations into well-argued conclusions based on solid evidence. We do have evidence to present, however, and indeed one or two conclusions that seem to us compelling. But if skeptics question their value, at least they will do so without envy, since they will not want to chase after our speculations on the Dreams—unless with the intention of chasing them and us out of the Cartesian arena altogether.Most of that arena is set aside for exegetical tussles with the respectable philosophizing of the Meditations, the Discourse on Method, and The Principles of Philosophy or The Passions of the Soul. But for some of the liveliest Cartesian games, you must move to that part of the arena where biographers, psychologists, psychoanalysts, and historians have fun with the "petit registre en parchemin," as the Stockholm Inventory describes it.1 This notebook contained [End Page 651] the twelve-page Olympica, in which Descartes recounted the three Dreams, announced his discovery of the foundations of "a wonderful science," and in the margin of the manuscript noted a year later his emerging understanding of "the foundation of a wonderful discovery." Later we'll rerun a few of the Olympian performances of previous interpreters, as preliminaries to a couple of our own interpretative games.First let us recall what happened on Saint Martin's Eve, the night of 10 November 1619, in Descartes's twenty-fourth year.2 In the days preceding that night Descartes's concern with the search for truth gave him much mental torment which the society of his friends could not dissipate. This tired him so much that his brain became inflamed: "he fell into a kind of enthusiasm, which left him in such a state that his depressed spirit was ready to receive dreams and visions." Retiring to bed "full of enthusiasm" from "having found that day the foundations of a wonderful science," Descartes (Baillet tells us) had three dreams "which he imagined could have come only from on high." In Dream I, while he was walking through the streets, his imagination was haunted by terrifying phantoms (fantômes). A severe disabling weakness in his right side forced him to bend over to his left so that he could continue toward his destination. Ashamed of walking in that way, he tried to straighten up, but a strong whirlwind spun him round three or four times on his left foot. Still more terrifying was the thought that he was falling at every step because of the difficulty in dragging himself through the streets.Then seeing a college with open gates, he entered, seeking relief from his afflictions, and intending to pray in the college chapel. But he had passed someone he knew without hailing him. He tried to return to greet him and was hurled back by the wind blowing against the chapel. At the same time he saw in the middle of the college courtyard another person who greeted him civilly by name, and told him that if he cared to look for Monsieur N., "he had something to give him." "M. Descartes imagined that it was a melon that someone had brought from some foreign country." But even more surprising was the fact that those who gathered round him to talk were standing straight and firm on their feet, whereas he was still bent over and staggering about, even though the wind which had threatened several times to blow him over had now greatly abated. At this point he awoke to feel a pain that made him fear that all this was the [End Page 652] work of... (shrink)

Most people in the philosophical world have combed, perused, written about, taught from, or at least heard of or wondered about the Leibniz-Clarke correspondence. So it’s surprising that until now there has been no full-scale study of these famous letters, though there are lots of articles that deal with various aspects of the exchanges. Perhaps it’s even more surprising because Ezio Vailati has shown how to manage a serious and ordered analysis of these exchanges. I suspect there are one or (...) two historians of early modern philosophy who are wishing they had had the same idea as Vailati and brought it to fruition. This is a welcome volume, combining analytic thoroughness with solid documentation. (shrink)

In 1996, Alan Sokal, a Professor of Physics at New York University, wrote a paper for the cultural-studies journal Social Text, entitled: 'Transgressing the Boundaries: Towards a transformative hermeneutics of quantum gravity'. It was reviewed, accepted and published. Sokal immediately confessed that the whole article was a hoax - a cunningly worded paper designed to expose and parody the style of extreme postmodernist criticism of science. The story became front-page news around the world and triggered fierce and wide-ranging controversy. -/- (...) Sokal is one of the most powerful voices in the continuing debate about the status of evidence-based knowledge. In Beyond the Hoax he turns his attention to a new set of targets - pseudo-science, religion, and misinformation in public life. 'Whether my targets are the postmodernists of the left, the fundamentalists of the right, or the muddle-headed of all political and apolitical stripes, the bottom line is that clear thinking, combined with a respect for evidence, are of the utmost importance to the survival of the human race in the twenty-first century.' The book also includes a hugely illuminating annotated text of the Hoax itself, and a reflection on the furore it provoked. (shrink)

When it was published in France, this book shocked the philosophers of the Left Bank with its plain-speaking attack on some of France's greatest minds.

More than any other figure, Friedrich Nietzsche is cited as the philosopher who anticipates and previews the philosophical themes that have dominated French theory since structuralism. Informed by the latest developments in both contemporary French philosophy and Nietzsche scholarship, Alan Schrift's Nietzsche's French Legacy provides a detailed examination and analysis of the way the French have appropriated Nietzsche in developing their own critical projects. Using Nietzsche's thought as a springboard, this study makes accessible the ideas of some of the most (...) important and difficult of contemporary French poststructuralist theorists including Jacques Derrida, Gilles Deleuze, Michel Foucault and Helene Cixous. Through a careful analysis and close reading of the texts of Nietzsche and French poststructuralism, Schrift illuminates the ways in which Nietzsche's thought prefigures certain poststructuralist motifs. He demonstrates how several dominant themes in contemporary Frenchphilosophy emerge out of Nietzsche's own thinking. As one of the first books to critically examine the work of the new French anti-Nietzschean's, Schrift defends the value of poststructuralism and Nietzsche as critical resources for confronting the present.

In spite of a powerful tradition, more than two thousand years old, that in a valid argument the premises must be relevant to the conclusion, twentieth-century logicians neglected the concept of relevance until the publication of Volume I of this monumental work. Since that time relevance logic has achieved an important place in the field of philosophy: Volume II of Entailment brings to a conclusion a powerful and authoritative presentation of the subject by most of the top people working in (...) the area. Originally the aim of Volume II was simply to cover certain topics not treated in the first volume--quantification, for example--or to extend the coverage of certain topics, such as semantics. However, because of the technical progress that has occurred since the publication of the first volume, Volume II now includes other material. The book contains the work of Alasdair Urquhart, who has shown that the principal sentential systems of relevance logic are undecidable, and of Kit Fine, who has demonstrated that, although the first-order systems are incomplete with respect to the conjectured constant domain semantics, they are still complete with respect to a semantics based on "arbitrary objects." Also presented is important work by the other contributing authors, who are Daniel Cohen, Steven Giambrone, Dorothy L. Grover, Anil Gupta, Glen Helman, Errol P. Martin, Michael A. McRobbie, and Stuart Shapiro. Robert G. Wolf's bibliography of 3000 items is a valuable addition to the volume. (shrink)

This paper targets the constitutive basis of social cognition. It begins by describing the traditional and still dominant cognitivist view. Cognitivism assumes internalism about the realisers of social cognition; thus, the embodied and embedded elements of intersubjective engagement are ruled out from playing anything but a basic causal role in an account of social cognition. It then goes on to advance and clarify an alternative to the cognitivist view; namely, an enactive account of social cognition. It does so first by (...) articulating a diachronic constitutive account for how embodied engagement can play a constitutive role in social cognition. It then proceeds to consider an objection; the causal-constitutive fallacy (Adams & Aizawa 2001, 2008; Block 2005) against enactive social cognition. The paper proceeds to deflate this objection by establishing that the distinction between constitution and causation is not co-extensive with the distinction between internal constitutive elements and external causal elements. It is then shown that there is a different reason for thinking that an enactive account of social cognition is problematic. We call this objection the ‘poverty of the interactional stimulus argument’. This objection turns on the role and characteristics of anticipation in enactive social cognition. It argues that anticipatory processes are mediated by an internally realised model or tacit theory (Carruthers 2015; Seth 2015). The final part of this paper dissolves this objection by arguing that it is possible to cast anticipatory processes as orchestrated as well as maintained by sensorimotor couplings between individuals in face-to-face interaction.
