Ce premier volume de La Nuit des Olympica. Essai sur le national cartésianisme (deux livres en quatre tomes) inaugure l'une des plus saines entreprises de la pensée contemporaine : que cesse le mythe Descartes! Finissons-en avec l'imagerie nationale. Suivons René Descartes dans les moments clés de sa vie, ancrons-le dans son époque de reconquête catholique et de consolidation de l'absolutisme. Traquons en ses feintes le premier de ces hommes en qui Nietzsche dénonçait un " prêtre masqué ", le philosophe. Multipliant (...) points de vue et rapprochements, enrichissant le texte de très abondantes notes, souvent surprenantes, l'auteur instruit le procès de cette source vive de la tradition française, rationaliste et spiritualiste, tant avec insolence et humour que dans une écriture aux antipodes de tout académisme.

The vertebrate retina is said to be inverted because the photoreceptors are oriented in the posterior direction and are thus unable to maximize photodetection under conditions of low illumination. The tapetum lucidum is a photoreflective structure located posterior to the photoreceptors in the eyes of some fish and terrestrial animals. The tapetum reflects light forward, giving incident photons a “second chance” to collide with a photoreceptor, substantially enhancing retinal photosensitivity in dim light. Across vertebrates (and arthropods), there are a wide (...) variety of tapeta that vary in structure, chemical composition, and even tissue architecture, indicating repeated convergent evolution. To date, the tapetum has not been observed in any cephalopod, however, which also possess a camera‐like eye, but with the retinal photoreceptors oriented in the anterior direction. We therefore hypothesize that the tapetum lucidum is a compensatory adaptation for the suboptimal design of the inverted retina of vertebrates. (shrink)

L'origine du Mal chez l'être humain demeure toujours une question sans véritable réponse officielle! Ainsi, à partir de l'expérience vécue de Gaston, un grand-père résistant, déporté et victime, l'auteur s'est efforcé de circonscrire une réflexion personnelle à cet inconnaissable-là, qui n'en finit pas de hanter la conscience des hommes. Pour y parvenir, il a fallu relier des pensées d'ordre utile dans les domaines aussi variés que la psychologie, la philosophie, l'anthropologie, l'ontologie et la spiritualité. Puis, les confronter à celles en (...) lien avec son expérience clinique d'arthérapeute analyste. Ce texte, aujourd'hui, en atteste : comprendre le Mal humain ne peut, ni faire l'économie d'une refonte globale de l'idée du Mal ni de la nécessité impérieuse de recourir à une introspection solitaire et solidaire pour conjurer cette malignité de l'âme. Le risque est permanent! Le Mal peut à chaque fois renaître, dès lors que nous sommes tous tentés de refouler cette question au plus profond de nos certitudes. (shrink)

Gerald Graff argues that our schools and colleges make the intellectual life seem more opaque, narrowly specialized, and beyond normal learning capacities than it is or needs to be. Left clueless in the academic world, many students view the life of the mind as a secret society for which only an elite few qualify. In a refreshing departure from standard diatribes against academia, Graff shows how academic unintelligibility is unwittingly reinforced not only by academic jargon and obscure writing, but (...) by the disconnection of the curriculum and the failure to exploit the many connections between academia and popular culture. Finally, Graff offers a wealth of practical suggestions for making the culture of ideas and arguments more accessible to students, showing how students can enter the public debates that permeate their lives.

Das Volksmärchen L’Arbre du Bœuf vom Typ ATU 511 [Ein-, Zwei-, Dreiäuglein] ist nach P. Delarue und M.-L. Tenèze das einzige französische Märchen, welches dem Subtyp AT 511 A [Kleiner Roter Ochse] angehört. L’Arbre du Bœuf ist darüber hinaus aufgrund einiger Motive besonders interessant, weil sie vermutlich aus archaischen Glaubensvorstellungen stammen: So ist die mystische „Reise zur Sonne“ ein bestimmendes Thema, welches seinen Ursprung im indoeuropäischen Mythos findet. Der Weltbaum als Axis Mundi und die Seelenbrücke sind Verbindungen zwischen dem Dies- (...) und Jenseits, die der Märchenheld ebenso wie der Schamane bei seiner ekstatischen Reise in die lichte Himmelswelt benutzt. Magische Tier- und Helferwesen treten im Zaubermärchen auf und sind integrale Bestandteile schamanistischer Glaubenswelten. Wenn im Märchen auf oder aus dem geopferten Ochsen als heiliges Tier der Weltbaum sprießt, so findet dieses Sujet Entsprechungen in urtümlichen Kosmogonien. Damit ideell verwandt ist vielleicht das Motiv vom „Tierhorn als Weltbaum“, welches sich in archaischen kosmologischen Vorstellungen findet und sich von da her womöglich ebenso in die Märchenwelten eingemischt hat. Le conte populaire L’Arbre du Bœuf du type ATU 511 [Un Œil, Deux Yeux, Trois Yeux] d’après P. Delarue et M.-L. Tenèze est le seul conte de fées français appartenant au sous-type AT 511 A [Petit Bœuf Rouge]. En outre, L’Arbre du Bœuf est particulièrement intéressant en raison de certains motifs probablement issus de croyances archaïques : Le « voyage mystique au soleil » est un thème déterminant qui tire son origine du mythe indo-européen. L’Arbre du Monde en tant qu’Axis Mundi et le pont d’autre monde sont des liens entre l’ici et l’au-delà, que le héros de conte et le chaman utilisent dans leur voyage extatique dans le ciel lumineux. Les animaux magiques et les êtres auxiliaires apparaissent dans le conte de fées et font partie intégrante du monde de croyances chamaniques. Tout comme dans le conte de fées, l’Arbre du Monde pousse sur ou bien du bœuf sacrifié et sacré, ce motif trouve des correspondances dans les anciennes cosmogonies. Le motif de la « corne animale en tant qu’Arbre du Monde » est peut-être associé à ce concept mythique. Il se trouve dans les conceptions cosmologiques archaïques et s’est mêlé de là au monde des contes de fées. The folk tale L’Arbre du Bœuf of the type ATU 511 [One Eye, Two Eyes, Three Eyes] is according to P. Delarue and M.-L. Tenèze the only French fairy tale that belongs to the subtype AT 511 A [Little Red Ox]. In addition, L’Arbre du Bœuf is particularly interesting due to some of the motifs that probably stem from archaic beliefs: The mystical “journey to the sun” is a determining theme, which finds its origin in the Indo-European myth. The World Tree as Axis Mundi and the Soul Bridge are connections between this world and the hereafter which are harnessed by the fairy tale hero as well as the shaman in his ecstatic journey into the bright world of heaven. Magical animals and helping entities appear in the fairy tale and are fundamental parts of shamanistic beliefs. The World Tree as it sprouts on or out of the sacrificed and sacred ox finds its equivalent in ancient cosmogonies. Perhaps ideally related to this is the motif of the “animal horn as the World Tree”, which is present in archaic cosmological conceptions and has possibly interfered with the fairytale worlds as well.

In this essay, I criticize Laudan's view that methodological rules in science are best understood as hypothetical imperatives, for example, to realize cognitive aim A, follow method B. I criticize his idea that such rules are best evaluated by a naturalized philosophy of science which collects the empirical evidence bearing on the soundness of these rules. My claim is that this view yields a poor explanation of (1) the role of methodological rules in establishing the rationality of scientific practices, (2) (...) the debates scientists have over rival methodological rules, and (3) the reasons on the basis of which scientists actually embrace, challenge, or transform methodological rules. A better explanation is provided by treating at least some methodological rules as foundational standards of theory-appraisal which define the criteria of scientific truth, knowledge, evidence, proof, explanations, etc., for a certain tradition or community of scientific practice. Such standards are in turn grounded or challenged on the basis of their coherence or incoherence with a wider body of scientific judgments. This view leads away from a naturalized philosophy of science back to its more classical epistemological conception. (shrink)

∗ This paper has been presented to the Philosophy Departments of Tulane University and the University of Arizona and, originally, to the 1999 Sociedad Filosofica Ibero Americana (SOFIA) Conference on Legal and Political Philosophy, in Mazatlan, Mexico. I am most thankful to all the participants. I am especially grateful for discussions with Julia Annes, Tom Christiano, Eric Mack, Geoff Sayre-McCord, David Schmidtz and Michael Smith.

The moral issues involved in doctors assisting patients to die with dignity are of absolutely central concern to the medical profession, ethicists, and the public at large. The debate is fuelled by cases that extend far beyond passive euthanasia to the active consideration of killing by physicians. The need for a sophisticated but lucid exposition of the two sides of the argument is now urgent. This book supplies that need. Two prominent philosophers, Gerald Dworkin and R. G. Frey present (...) the case for legalization of physician-assisted suicide. One of the best-known ethicists in the US, Sissela Bok, argues the case against. (shrink)

Does human nature possess normative significance? If so, what is it and what implications does it have for biotechnology? This essay critically examines three answers to these questions. One answer focuses on human nature as the ground of natural goods or goods dependent on human nature, another answer finds normative significance in the indeterminacy or malleability of human nature, and a third answer treats human nature as a natural sign of divine grace. Kathryn Tanner, who offers the second answer, and (...) Karl Barth, who offers the third, deny that nature has normative status in itself, apart from grace, but differ over the relation of grace to human nature as created. While indebted to Tanner, this essay favors Barth’s view as best suited to a Christian ethics of biotechnology. (shrink)

In this essay, I critically evaluate the approaches to explaining the success of science in Kuhn and the works of inference-to-the-best-explanation scientific realists. Kuhn ’s challenge to realists, who invoke the truth of theories to explain their success, is two-fold. His paradigm-account of success confronts realists with the problem of theory change, and the historical fact of successful theories later rejected as false. Secondly, Kuhn ’s account of the success of science has no need to bring truth into the explanation. (...) In turn, I argue that weakness in Kuhn and the prevailing forms of scientific realism motivate a better account of realism which I characterize as ‘best current theory realism’ and defend against the pessimistic meta-induction and the problem of theory-change. This realism argues that the best explanation of the success of current and past scientific theories only requires the simple claim that our best current theories are true. Kuhn ’s account can explain how normal science succeeds but cannot account for why its problem solutions work where they do and why they fail for other puzzles. (shrink)

In " Re-Emergence" he explores the question of conscious properties arising from brute, unthinking matter, making the case that there is no equally plausible non-emergent alternative.

What kind of thing is a reason for action? Are reasons for action subjective states of the agent, such as desires and/or beliefs? Or are they, rather, objective features of situations that favor certain actions? The suggestion offered in this article is that neither strategy satisfies. What is needed is a third category for classifying reasons which makes them out to be neither purely subjective nor purely objective. In brief: a reason for action is a feature of the situation that (...) matters to the agent. On this proposal, subjective states of the agent are indeed indispensable in characterizing reasons for action. Precisely which set of situational features matter to an agent—precisely what shape the agent experiences the situation as having—depends on the agent's psychological makeup. Those features themselves are not psychological states, however, and it is precisely those features that constitute the agent's reasons for action. (shrink)

O'Collins, Gerald Where was Christology, as developed not only by Roman Catholics but also by other Christians, heading when the Second Vatican Council closed on 8 December 1965? Any adequate stocktaking should take note of what was ending and what had already begun and would affect the future path of Christology.

What does it mean for Christ to be the "image of God"? And, if Christ is the "image of God," can the human person also unequivocally be understood to be the "image of God"? Augustine's Early Theology of Image examines Augustine's conception of the imago dei and makes the case that it represents a significant departure from the Latin pro-Nicene theologies of Hilary of Poitiers, Marius Victorinus, and Ambrose of Milan only a generation earlier. Augustine's predecessors understood the imago dei (...) principally as a Christological term designating the unity of divine substance. But, Gerald P. Boersma argues, Augustine affirms that Christ is an image of equal likeness, while the human person is an image of unequal likeness. Boersma's careful study thus argues that a Platonic and participatory evaluation of the nature of "image" enables Augustine's early theology of the image of God to move beyond that of his Latin predecessors and affirm the imago dei both of Christ and of the human person.

Parmenides didn't mention reference as such, but if he had he would have undoubtedly agreed with the philosophers who nowadays hold what is called "the axiom of existence": that one can only refer to what exists. The sources of possible support for this view are examined and rejected. Primary support for the axiom is given by two sorts of argument; one concerning quantification, the other summarizing a standard Parmenidean puzzle. Weaknesses in both are exposed. Finally, the relations between the axiom (...) and connected claims about predication and truth are probed, and an attempt is made to determine the limits of the mutual support these claims give one another.
