Le savoir comme construction
Authors: Lepage François
Published: April 2010

Le dernier ouvrage d'Yvon Gauthier, son quatrième, n'est certes pas d'une lecture des plus faciles. Le bon lecteur devrait à la fois être familier du formalisme de la mécanique quantique et des labyrinthes lacaniens, connaître la théorie des modéles êt etre revenu de Heidegger.

Tout cela rend la tâche d'un critique de Gauthier ardue et périlleuse; aussi je prierai le lecteur (le mien) de m'excuser à l'avance si, dans le foisonnement philosophique de l'ouvrage, j'ai dû restreindre mon attention à certains aspects particuliers.
L'imagination, produit d'une métaphore?
Authors: Lefebvre René
Published: April 2010

It would be contradictory to ask phainesthai to support both the strict sense (M. Schofield, M. Nussbaum), and metaphorical use (Simplicius) of phantasia. De anima, 428a2, raises many issues. When discovering imagination, Aristotle himself seems to use the word phantasia metaphorically.
La tension de la donation ultime et de la pensée herméneutique de l'application chez Jean-Luc Marion
Authors: Grondin Jean
Published: April 2010

La phénoménologie a connu trop peu de sommets créateurs depuis Husserl et Heidegger pour qu'il soit possible d'ignorer le dernier ouvrage de Jean-Luc Marion, aussi superbement écrit qu'il est ambitieux. Certes, de très exhaustives encyclopédies conçues par nos collègues américains, pour lesquels le terme de phénoménologie sert un peu d'équivalent à celui de philosophie continentale (c'est-à-dire «non analytique»!), recenseront des légions de phénoménologues depuis Husserl et Heidegger, mais aucun n'aura eu d'impact vraimentdéterminantsur la conception même de la discipline. Ces listes comprendront de redoutables penseurs comme Jean-Paul Sartre, Maurice Merleau-Ponty, Emmanuel Levinas et Paul Ricœur, où l'on reconnaîtra les plus illustres représentants de la tradition de la phénoménologie française (les autres traditions dites phénoménologiques étant beaucoup moins riches).
Moral Truth
Authors:   Ethics Research Group
Published: April 2010

Is worrying about whether moral judgments are true or false a philosophical waste of time? It can seem to be if moral truth claims are redundant on thejudgments they claim to be true. If to claim that the judgment “x is wrong” is true is simply to judge x wrong, anyone who is prepared to make judgments can consistently make truth claims. A concern for moral truth is then merely a concern for whether anything is right or wrong, not a separable concern for whether moral judgments are true or false.
Two Conceptions of the Structure of Happiness
Authors: Shea Joseph
Published: April 2010

It has been many years since the Classical notion of an objective, determinate account of the human good, applicable to all people, has played the central role in most moral theories. One contribution to this decline has been the Kantian belief that one cannot say what happiness is. Kant thinks that happiness is a purely empirical concept and is therefore dependent on contingent, unpredictable objects and states of affairs.
Natural-Agency Theory as an Alternative to Hume: A Reply to Andrew Ward
Authors: Gerwin Martin
Published: April 2010

Martin Gerwin répond ici aux critiques adressées par Andrew Ward à son article de 1987 « Causality and Agency: A Refutation of Hume». Contre la position de Hume sur l'origine de notre idée de connexion causale, Gerwin défend une théorie actantielle; il est de ceux pour qui le processus d'acquisition des concepts causaux dépend de manière cruciale de notre expérience d'être agent et non seulement spectateur. Il soutient que le processus implique un usage de l'imagination créatrice pour l'invention des concepts et des hypothèses, qui aurait été exclu par les principes de Hume, mais qui s'accorde bien avec les résultats de la psychologie expérimentale.
La logique peut-elle mouvoir l'esprit?
Authors: Engel Pascal
Published: April 2010

This paper attempts to take a new look at the famous Lewis Carroll paradox about Achilles and the Tortoise. It examines in particular the connections between Lewis Carroll's regress argument for logical inferences and a similar regress for practical inferences. The Tortoise's point of view is espoused: no norm of reasoning or of conduct can in itself “make the mind move,” only the brute force of belief can. This conclusion is a Humean one. But it does not imply that we renounce altogether the normative force of such principles of reasoning as modus ponens. Connexions with the Wittgensteinian rule-following problem are indicated.
Wittgenstein's Philosophy of Arithmetic
Authors: Joseph Marc A.
Published: April 2010

Cet article étudie les éléments centraux de la philosophic de l'arithmétique du premier Wittgenstein. Dans la première section, j'examine les traits de la conception du langage du Tractatus qui sont pertinents pour cette philosophic de l'arithmétique; l'accent est alors mis sur le concept de forme logique et sur la stratégie qu'emploie le Tractatus pour expliquer la signification des constantes logiques. Dans la deuxième section, je me tourne vers le traitement du nombre chez le premier Wittgenstein, en montrant ce qu'il doit à l'idée de forme du Tractatus et en l'intégrant au premier projet philosophique de Wittgenstein. J'esquisse enfin, brièvement, une voie qui, à partir de cette façon de comprendre l'arithmétique, conduit à quelques-unes des idées que l'on retrouve dans la philosophie postérieure de Wittgenstein.
Just Talk?
Authors: Weinstock Daniel M.
Published: April 2010

One of the most prominent themes of recent political philosophy, at least in the English-speaking world, has been the challenge which the cultural and moral diversity of modern Western societies poses for traditional liberal theories of justice. Given that these theories, in their classical formulations, either ignored the issue of social heterogeneity, or operated on the tacit assumption that the societies to which they would be applied were essentially homogeneous, what changes should a new appreciation of diversity impose upon both the content and the pattern of justification of theories of justice? Philosophers have been far from unanimous in their answers to this basic question. Some, like Will Kymlicka, have argued that recognizably liberal, autonomy-based justificatory arguments should lead us to change our view of liberalism's content, in that it should now incorporate collective rights to the traditional repertoire of individual rights. Others, like Iris Young, have argued that a real recognition of “difference” should lead to the wholesale abandonment of the liberal framework. Still others have argued that it is the manner in which liberalism goes about justifying normative principles that ought to be rethought, given the “fact of pluralism.” The disagreements on moral and political issues which are constitutive of modern societies have led some to argue that we can no longer hope to justify substantive principles deductively on the basis of general moral propositions taken as axiomatic. Authors who follow this line have argued that, in order not to tread on the moral or cultural toes of a diverse citizenry, liberal justification must ultimately reduce to the outcome of certain deliberative procedures. In radically plural societies, justified norms of social interactions are those to which people in conversation with one another would agree.
L'éristique mise en formules
Authors: Fait Paolo
Published: April 2010

L'objet principal de l'ouvrage d'Aristote intituléRéfutations sophistiquesest la théorie de la réfutation apparente, c'est-à-dire de l'argumentation qui, se développant dans le cadre d'un échange dialectique, masque quelque erreur. Aristote propose une taxinomie des réfutations apparentes d'après laquelle elles se rangent en deux groupes: celles qui relèvent du langage et celles qui n'en relèvent pas. Dans le premier groupe tombent six types de réfutation, l'homonymie, l'amphibolie, la liaison, la séparation, la forme de l'expression et l'accent; dans le deuxième l'accident, la conséquence, l'ignorance de la réfutation, la fausse cause, l'interrogation multiple, la pétition de principe et la confusion de l'absolu et du relatif. Il s'agit de la fameuse table des treize paralogismes oufallaciœque la tradition a consacrée. Dans le cadre de ces treize types de sophisme le texte d'Aristote nous offre la discussion de maints exemples parmi lesquels certains étonnent pour leur difficulté, d'autres pour leur trivialité.
La contrainte
Authors: Neuberg Marc
Published: April 2010

La réflexion philosophique sur le phénomène de la contrainte a été fortement marquée par l'analyse qu'en ont donné Aristote et saint Thomas. Cette analyse classique établit un critère très général de la contrainte mais n'aborde pas des questions plus spécifiques, telles que la distinction entre une tentative de contrainte et un avertissement ou la différence entre une offre et une tentative de contrainte. Ces distinctions, qui sont loin d'être évidentes (pour autant que I'on creuse quelque peu le sujet), présentent un intérêt non négligeable pour quiconque est amené à réfléchir sur des matières impliquant les relations humaines, tel le philosophe moral, le théoricien du droit, le sociologue ou l'économiste. Par exemple, peut-on dire que l'administration des contributions exerce une contrainte sur les contribuables en leur envoyant leur note d'imposition comportant un avertissement de payer dans les dix jours qui suivent la reception? Le détenteur d'un monopole — une société de distribution d'eau par exemple — contraint-il ses clients lorsqu'il augmente ses prix ou bien ne fait-il que changer les termes de son offre? Ce genre de questions ne peut pas recevoir de réponse dans l'analyse classique vu le niveau trap général de celle-ci.
Consciousness and Synchronic Identity
Authors: Matheson Carl
Published: April 2010

The question “What makes a group of simultaneous experiences the experiences of a single person?” has been nearly ignored in the philosophical literature for the past few decades. The most common answer (e.g., Parfit 1984) to this much neglected question is “Two simultaneous experiences belong to a single person if there is a common consciousness or awareness of them.” However, consciousness and awareness are difficult concepts to analyze, so that little of substance has been said of the answer. Recently, Oaklander has argued that the awareness answer is deficient for a different reason, claiming that it fails because “it ultimately rests on an analysis of the unity of consciousness that is itself circular or otherwise inadequate” Oaklander 1987, p. 525). Oaklander's criticism is especially interesting because, according to it, the awareness account of synchronic personal identity falls prey to the main problem facing the memory (or psychological connectedness) account of diachronic identity, namely the problem of branching. In this paper, I shall argue that there is no important symmetry. Whatever its other flaws may be, the awareness account is immune to the branching problem; its immunity is due to formal differences between synchronic and diachronic identity.
Wittgenstein on Logical Form and Kantian Geometry
Authors: Summerfield Donna M.
Published: April 2010

That Wittgenstein in the Tractatus likens logic to geometry has been noticed; however, the extent and force of the analogy he develops between logical form and a broadly Kantian account of geometry has not been sufficiently appreciated. In this paper, I trace Wittgenstein's analogy in detail by looking closely at the relevant texts. I then suggest that we regard the fact that Wittgenstein develops his account of logical form by analogy with a Kantian account of geometry as evidence for the bold thesis that Wittgenstein belongs within a Kantian epistemological tradition. Finally, I supply two small pieces of the interpretive puzzle needed to support the larger thesis: first, evidence that Wittgenstein's concern with logical form involves a crucial epistemological component; second, a sketch of how Wittgenstein's account of logical and mathematical knowledge can be viewed as continuing a Kantian tradition.

Kant's Transcendental Deductions
Authors: Glouberman Mark
Published: April 2010

In default of astounding findings — Lampe penned much of the critical corpus — it is likely that continued Kantian exegesis will perforce be featured by more pain for less gain. And since philosophical events must in many respects overtake even so monumental a figure as Kant, does not the treatment of Kantian documents in current terms court anachronism? In a fashion which encourages such musings, the contents of this handsomely produced collection of essays, the proceedings of a 1987 conference at Stanford, deviate from straight exegesis. The contributors include prominent commentators on Kant: Lewis White Beck, Paul Guyer, Jules Vuillemin. A number — P. F. Strawson, John Rawls, Stuart Hampshire — are original philosophers of high calibre. Given the divergent pressures of textual fidelity, of novelty, and of philosophicality, the interaction challenges us to consider the prospects. An especially illuminating portion of the discussion in this regard brings together Dieter Henrich, Guyer, and Strawson.
The Responsibilities of Scientists

Published: April 2010

The high quality of the 20 papers in this collection is evidence that even in an area which has been repeatedly mined, there is always room for interesting, well presented thought.

The authors represented include both philosophers and working scientists. Some are well known contributors to philosophical discussion, while the work of others (including a number of European scientists and philosophers) will be less familiar to North American journal audiences.
Quine's Truth: The Unending Pursuit
Authors: Patton Thomas E.
Published: April 2010

This book is both shorter and more comprehensive than any of Quine's other six since Word and Object. But let this description raise no fears that it must stretch itself too thin, at least for veteran students of his major philosophical project, “to examine the evidential support of science” (p. 2). For with less detail in focus, the structural elements of that project stand revealed as never before. Improvements in presentation, as Quine sees them, help here. And veterans can learn of certain changes, notable if not huge, in various Quinean views. For besides summing up and explaining, Pursuit of Truth moves on.
Foucault historien et “historien ” du présent
Authors: Kaufmann J. N
Published: April 2010

Michel Foucault disait de ses propres travaux qu'ils avaient été des essais aveugles (Archéologie du savoir, 26) qui ne s'éclairaient qu'en cours de route, au fur et à mesure que se précisait la méthode d'analyse historique qui y était appliquée. Us ont été reçus comme oeuvres d'his-torien. Cet accueil laissait cependant l'inconfortable impression que Foucault envahissait le champ de l'histoire en se comportant en his-torien cannibale, en dissolvant de son regard de sauvage les évidences incontestées et en résolvant avec facilité les problèmes sur lesquels les spécialistes se cassaient les dents. Cela lui a valu une réception controversée. Foucault eut, en effet, maille à partir non seulement avec les historiens, mais aussi avec les spécialistes des disciplines auxquelles il s'intéressait. De plus, chaque fois qu'on lui demandait de définir le “point d'où il soulevait la terre épistémique ”, de circonscrire l'espace blanc où il s'installe quand il fait ses enquêtes et fabrique les histoires sur l a folie, sur la maladie et la naissance de la clinique, sur l'apparition des sciences de la vie, du langage et de l'économie, sur la naissance de la prison et sur l'usage des plaisirs des grecs au dix-neuvième siècle, Foucault répondait en véritable anarchiste qu'il n'était ni ceci, ni cela, qu'il était plutôt contre toutes ces étiquettes que l'on essayait de lui coller.
How Scientific Laws Can Be About Individuals
Authors: Martin Robert M.
Published: April 2010

The assumption is often made that there cannot be scientific laws about individuals. I shall try to provide a plausible semantics and epistemology for scientific laws about individuals. This would be interesting, however, only ifone were tempted to believe that mentioning individuals did not disqualify a sentence from scientific lawhood. To begin with, I will try to provide such a temptation.
“I Don't Get No Respect
Authors: Cooper W. E.
Published: April 2010

The author struggles to come to grips here with the philosophical complexities and personal tragedies that disorient us when we reflect on the great and pervasive inequalities in human societies. His egalitarianism is radical in denying the justice of the inequalities that liberals like Rawls would countenance, and in denying that justice and capitalism are compatible. Nielsen displays a masterly knowledge of the literature of social justice, especially that which bears on Rawls's A Theory of Justice and Nozick's Anarchy, State and Utopia, the celebrated philosophical flagships of liberalism and conservatism respectively; this feature of the book should be useful for advanced students of social and political philosophy who need to acquire a sense for the texture of contemporary argument in the field. The thicket of sturdy arguments in Equality and Liberty should convince Rawlsians to accept many tenets of Nielsen's radical egalitarianism, or else to re-examine their thinking about social justice. And the extended critique of Anarchy, State and Utopia should persuade Nozickians of the need for “a reasonably sophisticated political sociology and a sound critical theory of society” if one is to philosophize adequately about social justice (5). Many will find this critique the most valuable part of the book.
The Formalist Treatment of Spinoza
Authors: Maxwell Vance
Published: April 2010

Professor Bennett's new book on Spinoza is a notably ambitious one. It i s ambitious in two ways. First, having worked on the book for twenty-five years, Bennett intends a treatment of Spinoza's Ethics at once comprehensive in scope and detailed in analysis. He tells us that his book “expounds and argues with Spinoza's Ethics, in the hope of drawing into the argument philosophers who have not previously brought Spinoza into their work as an energetic collaborator or antagonist” (1). Second, Bennett claims to have written a book superior to other commentaries in that “The courtly deference which pretends that Spinoza is always or usually right, under some rescuing interpretation is one thing; it is quite another to look to him, as I have throughout this book, as a teacher, one who can help us to see things which we might not have seen for ourselves. This is showing him a deeper respect, but also holding him to a more demanding standard” (372).
Erratum
Authors: Armour Leslie
Published: April 2010

In our article, “The Faces of Reason and Its Critics”, Dialogue 25/1 (Spring 1986), 105–118, Elizabeth Trott and I said (106) that, in his presidential address to the Canadian Philosophical Association (Dialogue 16/1 [March 1977], 3–21), Francis Sparshott “mysteriously seemed to have confused … John Clark Murray … with John Macmurray”. In footnote 6 (107), we reported Martyn Estall's theory that there might, indeed, have been no confusion because Sparshott probably did mean Macmurray who was being “promoted” at Queen's at the time. Professor Sparshott reports that Professor Estall's surmise is the correct solution to the “mystery”. He also reminds us that, when he came to Canada in 1950 he was at University College, Toronto. Later, from 1955 onwards, he was John Irving's colleague at Victoria College.
From Concept to Judgement: Rethinking Hegel's Overcoming of Formal Logic
Authors: Winfield Richard Dien
Published: April 2010

La doctrine hégélienne du concept et du jugementpermet une approche à la fois non circulaire et non formelle, capable de légitimer lew rôle privilégié comme véhicules de la vérité. Pour le voir, ilfaut d'abord clarifier le rapport intrinsèque entre le concept, l'autodétermination et les catégories d'universalité, de particularité et d'individualité. Au cœur de ce rapport se trouve la manière dont l'universalité, la particularité et l'individualité sont elles-mêmes interreliées. Cette interconnexion peut sembler prendre tour à tour deux formes différentes, l'une qui se manifeste dans les jugements où l'individu opère comme universel particularisé, et l'autre qui apparait lorsque l'individu englobe l'universel particularisé. Ces caractéristiques ne sont pas exclusives l'une de l'autre; mais c'est plutôt que I'individualité comme universel particularisé sous-tend l'individualité comme particulier différencié et entraine ainsi la détermination du jugement dans lequel ce dernier se trouve contenu. La compréhension de ces rapports fournit la clé pour concevoir de manière non arbitraire la relation qu'ily a entre le concept et le jugement.
The Infinite Movement of Self-Conception and Its Inconceivable Finitude: Hegel onLogosand Language
Authors: De Boer Karin
Published: April 2010

Bien que Hegel soit parfaitement conscient du fait que l'activité de penser nepuisse devenir ce qu'elle est que dans etpar le langage, on peut dire qu'ila préservé une distinction hiérarchisée entre la pensée et le langage dans lequel elle s'exprime. Dans le but de clarifier ce qu'il veut dire exactement lorsqu'il distingue entre, d'un côté, la totalité des concepts purs et, de l'autre, le langage, la première partie du présent article—qui en est aussi la plus longue—fournit une interprétation deplusieurs textes de Hegel sur le rapport entre la pensée pure et le langage, et montre pourquoi la conception qu'il se fait de cette relation est plus difficile à critiquer qu'on ne l'a souvent cru. L'article part de la conception hégélienne du concept absolu et, après avoir briévement esquissé la relation entre la Logique et la philosophic de la nature et de l'esprit, examine divers passages sur le langage, tirés, entre autres, des leçons sur la philosophic de l'histoire mondiale. La deuxième partie de l'article propose—dans une veine heideggérienne—une perspective à partir de laquelle une déconstruction des présupposés de base de cette conception pourrait avoir quelque chance de succès.
Les mathématiques sont-elles une syntaxe du langage?
Authors: Gödel Kurt
Published: April 2010

Nous publions sous ce titre la traduction française de l'essai philosophique de Kurt Gödel intitulé: «Is Mathematics Syntax of Language?» Inédit jusqu'à présent, l'original paraîtra dans le 3e volume des Collected Works de Gödel, dont la publication est imminente. Nous savons par Hao Wang que, le 15 mai 1953, Paul Arthur Schilpp avait invité Gödel à apporter sa contribution au volume consacré à Carnap dans The Library of Living Philosophers. Le manuscrit de Gödel «Carnap and the Ontology of Mathematics», devait être remis au plus tard le 2 avril 1954. Dés le 2 juillet 1953, Gödel donnait son accord à Schilpp pour la rédaction d'un article intitulé «Some Observations on the Nominalistic View of the Nature of Mathematics.» Cependant, le volume consacré à Carnap paraîtra en 1963 sans qu'y figure la contribution de Gödel. En effet — toujours selon Wang — Gödel avait informé Schilpp, le 2 février 1959, qu'il renonçait à l'envoi de l'article, dont il avait composé, surtout en 1954–1955, plusieur s versions sous le titre «Is Mathematics Syntax of Language?» Pour expliquer cet abandon, Wang avance les raisons suivantes: En premier lieu, Gödel était bien convaincu d'avoir réfuté la thése syntaxique, mais il n'était pas satisfait de son argumentation en faveur du platonisme. Deuxiémement, les critiques de Gödel s'adressent aux théses soutenues par Carnap en 1934 plutôt qu'à celles que ce dernier défendra vingt ans aprés, et qui paraissent moins hostiles au platonisme de son interlocuteur. II pouvait paraître douteux, en troisieme lieu, que Carnap ait eu le temps de rédiger, en 1959, la réponse qu'il aurait du faire, conformément aux régies de la collection, à Gödel. Or, en 1943 déjà, Gödel avait voulu retirer sa contribution au volume consacré à Russell dans la même serie, parce que ce dernier n'avait pu répondre à l'article de Gödel dont la rédaction lui avait été communiquée trop tardivement.
Shame and Blame: The Self through Time and Change
Authors: Radden Jennifer
Published: April 2010

Do our customary notions of shame, blame and guilt require us to adopt a particular view of the self's singularity and invariance through time? Consider the intriguing case of John Demjanjuk, tried in Israel during 1987 and 1988 for the crimes of “Ivan the Terrible,” a concentration camp guard at Treblinka in Poland, during 1942–43. John Demjanjuk, a retired factory worker living in Cleveland, Ohio, appeared banal at his trial—old, quiet, ordinary and helpless; descriptions from survivors of Treblinka cast Ivan as monstrous in his vigorous brutality. Should John be found guilty and punished for Ivan's crimes? This question takes us beyond any answers sought at the trial. Even if the spatio-temporal identity of the later John and earlier Ivan had been established conclusively, still the justice of punishing the later man for the earlier one's crimes may be questioned. For a philosophical puzzle of personal identity lingers: is the later John the same person as the earlier Ivan? In cases such as this the passage of time and radical changes of character and personality seem to invite the notion that one self or person has succeeded another in the same body. If this were so, would—or should—culpability transfer undiminished from one self to another?
Justified Belief
Authors: Goldstick D.
Published: April 2010

A “hypothetical imperative” tells what to do to get a certain result. Equivalently, it says what is the “right” thing to do to achieve that result. Insofar as achieving that result is the sole end in view, wondering what is the right thing to do to achieve it just is: wondering what to do. Insofar as it is the sole end in view, deciding what is the right thing to do to achieve it is simply deciding what to do. Something's being the right thing to do to achieve a certain goal does not, of course, guarantee that it actually will succeed in achieving that goal: the meaning is only that, in the existing circumstances, it is more apt to achieve the goal than any available alternative.
From Königsberg to Vienna: Coffa on the Rise of Modern Semantics
Authors: Creath Richard
Published: April 2010

Shortly before he died Alberto Coffa said he was writing “a very grumpy book.” It has turned out to be grumpy indeed, but also funny and deep and wonderful. When he began his work nearly 20 years ago he chose what must have seemed the most unpromising topic imaginable: the history of the a priori, both in the nineteenth century and especially among the logical positivists in the decade following 1925. In the early 1970s it was risky for a promising young philosopher of science to concentrate on historical topics. The nineteenth century was, with a few notable exceptions, terra incognita to analytically inclined philosophers. The positivists were pariahs. And many philosophers were convinced that there was no such thing as the a priori to be studied. Times have changed a bit, but this book still covers new territory. And though I cannot accept all of his conclusions, Coffa has much to teach, perhaps especially to those who would have found the whole investigation unpromising.
L'infinité divine dans l'Antiquité et au Moyen Âge
Authors: Côté Antoine
Published: April 2010

Vers la fin des années cinquante, un jeune érudit jésuite publia un article intitulé «AreApeiriaandAoristiaSynonyms?» qui allait être le premier d'une longue série de travaux portant sur une problématique à laquelle il s'attaquait en véritable pionnier: la doctrine de l'infinité divine dans l'Antiquité et au Moyen Âge. Certes, les historiens s'étaient déjà intéressés quelque peu à cette question, mais ils l'avaient fait sans une conscience claire de sa complexité. Force était donc de reprendre la problématique à nouveaux frais. C'est ce que fit Leo Sweeney, qui publiera, sur une carrière de plus de trentecinq ans, une quantité impressionnante d'articles étudiant les conditions de l'émergence de l'infinité divine au Moyen Âge, ainsi que la conception de l'infíni chez les grandes fígures de l'Antiquité et du christianisme médiéval. Ce sont ces articles, dont certains ont fait l'objet de profonds remaniements, et auxquels viennent s'ajouter deux travaux inédits, qu'a réunis l'éditeur Peter Lang dans un ouvrage de près de six cents pages, dont il faut bien dire qu'il constitue une manière d'événement dans le monde des études anciennes et médiévales.
Is There Any Ontology in Aristotle?
Authors: Owens Joseph
Published: April 2010

The term “ontology”, as is well enough known, is of seventeenth-century vintage. According to current research, it first appears in the year 1613. By the end of the century it had waxed firm in common recognition. Through the influence of Christian Wolff in the following century, the eighteenth, it quickly became standard in the school tradition for the science of being in general, the science of beingquabeing. In its morphology the term showed clearly enough that it was meant to designate a science that bore upon being in the widest range of the notion. In that tenor it was described at the time asmetaphysica de ente, philosophia de ente, doctrina de ente, orentis scientia, in the sense that “being” denoted its proper subject matter (objectum proprium) more correctly than did “metaphysics”.' Accordingly, it was intended to imply that “being”,tout court, was to be regarded as the object of a philosophical science quite as “soul”, for instance, played the role of object for psychology.
Forrester's Paradox
Authors: Jacquette Dale
Published: April 2010

In “Gentle Murder, Or The Adverbial Samaritan”, James William Forrester presents what he describes as “the most powerful version yet put forward” of Lennart Åqvist's Good Samaritan paradox in deontic logic. Forrester suggests that the paradox may make it necessary to reject the standard deontic inference principle

(where “r” is an index for any source of obligation). This desperate conclusion, as Forrester acknowledges, would imply that all of standard deontic logic “must be in a bad way”. But Forrester's “paradox” is not nearly so deep or intractable as he maintains.
COMING TO TERMS WITH THE PAST: GERMAN ACADEMIA AND HISTORICAL RELATIONS BETWEEN THE ARAB LANDS AND NAZI GERMANY
Authors: Wien Peter
Published: April 2010

The books that are the subject of this review essay comprise three new contributions and one revised edition about a topic that has become paradigmatic in defining scholarly and political approaches to key areas of Middle Eastern history. It has shaped studies of the historical and ideological roots of Arab nationalism, the Arab–Israeli conflict, and the emergence and perseverance of authoritarian regimes in the modern Middle East. The ways that politicians, intellectuals, political movements, and the Arab public related to Nazism and Nazi anti-Semitism have been used to contest the legitimacy of 20th-century Arab political movements across the ideological spectrum. Historians have theorized about the involvement of individuals such as Grand Mufti Amin al-Husseini in the crimes of Adolf Hitler, Heinrich Himmler, and Adolf Eichmann; the roots of Arab nationalist doctrine in German Volk ideas; the mimicry of Nazism in organizations such as the Iraqi al-Futuwwa and Antun Saadeh's Syrian Social Nationalist Party; and Arab public sympathies for Nazi anti-Semitism dating from the 1930s or even earlier. Until recently, European and Anglo-American research on these topics—often based on a history of ideas approach—tended to take a natural affinity of Arabs toward Nazism for granted. More recent works have contextualized authoritarian and totalitarian trends in the Arab world within a broad political spectrum, choosing subaltern perspectives and privileging the analysis of local voices in the press over colonial archives and the voices of grand theoreticians. The works of Israel Gershoni have taken the lead in this emerging scholarship of Arab nationalism. This approach was also the common denominator of a research project on “Arab Encounters with National Socialism,” which the Berlin Center for Modern Oriental Studies (Zentrum Moderner Orient) hosted from 2000 to 2003. Its members included the author of this review and the authors of two of the books under review (Nordbruch and Wildangel). The project used indigenous Arabic sources, especially local newspapers, for a close scrutiny of Arab reactions to the challenge of Nazism in a period when Arabs, especially nationalists, perceived that quasicolonial regimes undermined the ostensibly democratic and liberal ethos of the British and French Mandate powers.
LIMINAL CRAFT, EXCEPTIONAL LAW: PRELIMINARY NOTES ON MIDWIVES IN MEDIEVAL ISLAMIC WRITINGS
Authors: Giladi Avner
Published: April 2010

In this article, the first fruit of an ongoing research on the sociocultural history of midwifery in medieval Muslim societies, I trace the attitudes toward midwives as revealed in Arabic biographical, medical, and legal texts. These texts, the product of male scholars, mirror an ambivalent attitude toward midwives: a mixture of repressed admiration, open repulsion, and fear. Thus, midwives are almost totally absent from Islamic scriptures, and Muslim writers make them play only a minor role in biographical and hagiographic literature, where the midwives of the Prophet's family are consciously or unconsciously “blocked” from becoming mythological figures. Women, sometimes hesitatingly identified as midwives, nevertheless played a role through their very presence at the moment of the Prophet's birth. In a storylike manner, they set an example for the implication of the legal rules concerning the midwife's exceptional status as a witness in court, rules that were formulated and consolidated in the formative period of Islamic law side by side with the traditions on the Prophet Muhammad's birth.
The effect of confining impermeable boundaries on gravity currents in a porous medium
Authors: GOLDING MADELEINE J. , HUPPERT HERBERT E.
Published: April 2010

The effect of confining boundaries on gravity currents in porous media is investigated theoretically and experimentally. Similarity solutions are derived for currents when the volume increases as tα in horizontal channels of uniform cross-section with boundary height b satisfying b ~ a|y/a|n, where y is the cross-channel coordinate and a is a length scale of the channel width. Experiments were carried out in V-shaped and semicircular channels for the case of gravity currents with constant volume (α=0) and constant flux (α=1). These showed generally good agreement with the theory.

Typically, we find that the propagation of the current is well described by L ~ tc for some scalar c. We study the dependence of c on the time exponent of the volume of fluid in the current, α, and the geometry of the channel, parameterized by n. For all channel shapes, there exists a critical value of α, αc = 1/2, above which increasing n causes an increase in c and below which increasing n causes a decrease in c, where increasing n corresponds to opening up the channel boundary to the horizontal. The current height increases or decreases with respect to time depending on whether α is greater or less than αc. It is this fact, along with global mass conservation, which explains why varying the channel shape n affects the propagation rate c in different ways depending on α.

We also consider channels inclined at an angle θ to the horizontal. When the slope of the channel is much greater than the slope of the free surface of the current, the component of gravity parallel to the slope dominates, causing the current to move with a constant velocity, Vf say, regardless of channel shape n and flux parameter α, in agreement with results for a two-dimensional gravity current obtained by Huppert & Woods (1995) and some initially axisymmetric gravity currents presented by Vella & Huppert (2006). If the effect of the component of gravity perpendicular to the channel may not be neglected, i.e. if the slopes of the channel and free surface of the current are comparable, we find that, in a frame moving with speed Vf, the form of the governing equation for the height of a current in an equivalent horizontal channel is recovered. We calculate that the height of a constant flux gravity current down an inclined channel will tend to a fixed depth, which is determined by the channel shape, n, and the physical properties of the fluid and rock. Experimental and numerical results for inclined V-shaped channels agree very well with this theory.
Gravity current flow past a circular cylinder: forces, wall shear stresses and implications for scour
Authors: GONZALEZ-JUEZ E. , MEIBURG E. , TOKYAY T. , CONSTANTINESCU G.
Published: April 2010

The flow of compositional gravity currents past circular cylinders mounted above a wall is investigated numerically. Two- and three-dimensional Navier–Stokes simulations are employed to quantify the force load on the cylinder, along with the friction velocity at the bottom wall near the cylinder, for Reynolds numbers in the range of 2000–45 000. While two-dimensional simulations accurately capture the impact stage, they are seen to overpredict the force and friction velocity fluctuations throughout the transient stage. Comparisons between gravity current and constant-density flows past circular cylinders show that the impact and transient stages are unique to gravity current flows. During the quasi-steady stage, on the other hand, the wake structures and the values of the drag, the peak-to-peak lift, the vortex shedding frequency and the friction velocity below the cylinder are comparable.

The friction velocity below the cylinder depends chiefly on the Reynolds number formed with the front velocity and the gap width. The maximum friction velocity at impact is about 60% larger than during the quasi-steady stage or in a constant-density flow. This raises the possibility of aggressive erosion behaviour at impact, which may occur in a spanwise localized fashion because of the larger friction velocity near the lobes.
Large-scale structures in turbulent and reverse-transitional sink flow boundary layers

Published: April 2010

Aspects of large-scale organized structures in sink flow turbulent and reverse-transitional boundary layers are studied experimentally using hot-wire anemometry. Each of the present sink flow boundary layers is in a state of ‘perfect equilibrium’ or ‘exact self-preservation’ in the sense of Townsend (The Structure of Turbulent Shear Flow, 1st and 2nd edns, 1956, 1976, Cambridge University Press) and Rotta (Progr. Aeronaut. Sci., vol. 2, 1962, pp. 1–220) and conforms to the notion of ‘pure wall-flow’ (Coles,J. Aerosp. Sci., vol. 24, 1957, pp. 495–506), at least for the turbulent cases. It is found that the characteristic inclination angle of the structure undergoes a systematic decrease with the increase in strength of the streamwise favourable pressure gradient. Detectable wall-normal extent of the structure is found to be typically half of the boundary layer thickness. Streamwise extent of the structure shows marked increase as the favourable pressure gradient is made progressively severe. Proposals for the typical eddy forms in sink flow turbulent and reverse-transitional flows are presented, and the possibility of structural self-organization (i.e. individual hairpin vortices forming streamwise coherent hairpin packets) in these flows is also discussed. It is further indicated that these structural ideas may be used to explain, from a structural viewpoint, the phenomenon ofsoftrelaminarization or reverse transition of turbulent boundary layers when subjected to strong streamwise favourable pressure gradients. Taylor's ‘frozen turbulence’ hypothesis is experimentally shown to be valid for flows in the present study even though large streamwise accelerations are involved, the flow being even reverse transitional in some cases. Possible conditions, which are required to be satisfied for the safe use of Taylor's hypothesis in pressure-gradient-driven flows, are also outlined. Measured convection velocities are found to be fairly close to the local mean velocities (typically 90% or more) suggesting that the structure gets convected downstream almost along with the mean flow.
Dynamics of concentrated suspensions of non-colloidal particles in Couette flow
Authors: YEO KYONGMIN , MAXEY MARTIN R.
Published: April 2010

Fully three-dimensional numerical simulations of concentrated suspensions of O(1000) particles in a Couette flow at zero Reynolds number are performed with the goal of determining the wall effects on concentrated suspensions of non-colloidal particles. The simulations, based on the force-coupling method, are performed for 0.2 ≤ φ ≤ 0.4 and 10 < Ly/a < 30, where φ denotes the volume fraction and Ly and a are, respectively, the channel height and the particle radius. It is shown that the suspensions can be divided into three regions depending on the microstructures; the wall region where a structured particle layering is dominant, the core region in which the suspension field is quasi-homogeneous, and the buffer region which shows the characteristics of both the particle layer and the shear structure. The width of the inhomogeneous region (wall and buffer) is a function of φ and not sensitive to Ly/a, once Ly/a is larger than a threshold. Rheological properties in the inhomogeneous and quasi-homogeneous regions are investigated. The particle stresses are compared with previous rheological models.
Air cushioning and bubble entrapment in three-dimensional droplet impacts
Authors: HICKS PETER D. , PURVIS RICHARD
Published: April 2010

Droplet deformation by air cushioning prior to impact is considered. A model is presented coupling the free-surface deformation of a droplet with the pressure field in the narrow air layer generated as a droplet approaches an impact. The model is based upon the density and viscosity in the air being small compared with those in the liquid. Additionally, the Reynolds number, defined using the droplet radius ℛ and approach velocity l, is such that lubrication forces dominate in the air layer. In the absence of significant surface tension or compressibility effects, these assumptions lead to coupled nonlinear integro-differential equations describing the evolution of a droplet free surface approaching a solid wall through air, with or without topography.

The problem is studied numerically with a boundary-element method in the inviscid droplet coupled with a finite-difference method in the lubricating air. In normal impacts, air cushioning will be shown to deflect the free surface upwards, delaying the moment of touchdown and trapping a bubble. The volume of the bubble is found to be (μg4/3ℛ5/3/ρl4/3l4/3), where μg is the gas viscosity and ρl is the liquid density and the numerically computed pre-factor = 94.48. Bubble volumes predicted by this relationship are shown to be in good agreement with experimental observations. In oblique impact or impact with a moving surface with sufficient horizontal motion a bubble is not trapped beneath the approaching droplet. In this case, the region of touchdown is initially crescent shaped with air effects accelerating the moment of touchdown.
Turbulent rotating convection at high Rayleigh and Taylor numbers

Published: April 2010

We report heat transport measurements in a cylindrical convection apparatus rotating about the vertical axis. The aspect ratio was 1/2. The working fluid was cryogenic helium gas and the following parameter ranges applied: the Rayleigh number, Ra, varied in the range 1011 < Ra < 4.3 × 1015, the Taylor number, Ta, varied in the range 1011 < Ta < 3 × 1015, the convective Rossby number, Ro, varied in the range 0.4 < Ro < 1.6 and the Prandtl number, Pr, varied in the range 0.7 < Pr < 5.9. Boussinesq conditions applied quite closely. The heat transport for steady rotation, under all conditions of the present experiments, was smaller than that for the non-rotating case. When the rotation rate varied periodically in time, a sharp transition to a state of significantly enhanced heat transport was observed for modulation Taylor numbers Ta* ≳ 1014, where Ta* is based on the peak value of the modulation angular velocity.
Segregation of particles in incompressible random flows: singularities, intermittency and random uncorrelated motion
Authors: IJZERMANS RUTGER H. A. , MENEGUZ ELENA , REEKS MICHAEL W.
Published: April 2010

The results presented here are part of a long-term study in which we analyse the segregation of inertial particles in turbulent flows using the so called full Lagrangian method (FLM) to evaluate the ‘compressibility’ of the particle phase along a particle trajectory. In the present work, particles are advected by Stokes drag in a random flow field consisting of counter-rotating vortices and in a flow field composed of 200 random Fourier modes. Both flows are incompressible and, like turbulence, have structure and a distribution of scales with finite lifetime. The compressibility is obtained by first calculating the deformation tensor Jij associated with an infinitesimally small volume of particles following the trajectory of an individual particle. The fraction of the initial volume occupied by the particles centred around a position x at time t is denoted by |J|, where J ≡ det(Jij) and Jij ≡ ∂xi(x0, t)/∂x0,j, x0 denoting the initial position of the particle. The quantity d〈ln|J|〉/dt is shown to be equal to the particle averaged compressibility of the particle velocity field 〈∇ · v〉, which gives a measure of the rate-of-change of the total volume occupied by the particle phase as a continuum. In both flow fields the compressibility of the particle velocity field is shown to decrease continuously if the Stokes number St (the dimensionless particle relaxation time) is below a threshold value Stcr, indicating that the segregation of particles continues indefinitely. We show analytically and numerically that the long-time limit of 〈∇ · v〉 for sufficiently small values of St is proportional to St2 in the flow field composed of random Fourier modes, and to St in the flow field consisting of counter-rotating vortices. If St > Stcr, however, the particles are ‘mixed’. The level of mixing can be quantified by the degree of random uncorrelated motion (RUM) of particles which is a measure of the decorrelation of the velocities of two nearby particles. RUM is zero for fluid particles and increases rapidly with the Stokes number if St > Stcr, approaching unity for St ≫ 1. The spatial averages of the higher-order moments of the particle number density are shown to diverge with time indicating that the spatial distribution of particles may be very intermittent, being associated with non-zero values of RUM and the occurrence of singularities in the particle velocity field. Our results are consistent with previous observations of the radial distribution function in Chun et al. (J. Fluid Mech., vol. 536, 2005, p. 219).
Transient flow of a viscous compressible fluid in a circular tube after a sudden point impulse transverse to the axis
Authors: FELDERHOF B. U.
Published: April 2010

The flow of a viscous compressible fluid in a circular tube generated by a sudden impulse at a point on the axis and directed transverse to the axis is studied on the basis of the linearized Navier–Stokes equations. A no-slip boundary condition is assumed to hold on the wall of the tube. The flow behaviour differs qualitatively from that for a point impulse in the direction of the axis in that there is no coupling to a diffusive sound mode. As a consequence, the transverse velocity autocorrelation function of a suspended Brownian particle decays at long times faster than t−3/2.
