The well-known game of chess has traditionally been modeled in artificial intelligence studies by search engines with advanced pruning techniques. The models were thus centered on an inference engine manipulating passive symbols in the form of tokens. It is beyond doubt, however, that human players do not carry out such processes. Instead, chess masters instead carry out perceptual processes, carefully categorizing the chunks perceived in a position and gradually building complex dynamic structures to represent the subtle pressures embedded in the (...) positions. In this paper we will consider two hypotheses concerning the underlying subcognitive processes and architecture. In the first hypothesis, a multiple-leveled chess representational structure is presented, which includes distance graphs (with varying levels of quality) between pieces, piece mobilities, and abstract roles. These representational schemes seem to account for numerous characteristics of human player’s psychology. The second hypothesis concerns the extension of the architecture proposed in the Copycat project as central for modeling the emergent intuitive perception of a chess position. We provide a synthesis on how the postulated architecture models chess intuition as an emergent mixture of simultaneous distance estimations, chunk perceptions, abstract role awareness, and intention activations. This is an alternative model to the traditional AI approaches, focusing on the philosophy of active symbols. (shrink)
Jean-Guillaume-César-Alexandre-Hippolyte de Colins (1783-1859), a Belgian baron who lived mainly in Paris, sought to develop a position—rational socialism—intermediate between the extremes of full capitalism (with only private property) and full communism (with only collective property). All persons fully own themselves and the artifactual wealth that they produce, and they are entitled to an equal share of the natural resources and of the assets inherited from previous generations. Gifts and bequests are to be subject to heavy taxation (although at less (...) than 100% of their value, for efficiency reasons). Natural resources are subject to a rent-tax. A warning about the following reading: Colins writes in many places as if he held that an unrestricted right to make gifts and bequests is both necessary for efficient social functioning and required by justice. His ultimate view, however, is that efficient social functioning requires only some kind of weak (partially restricted) right to make gifts and bequest, and that justice does not require any such right. More specifically, he holds that justice requires that gifts and bequests be taxed as much as compatible with efficient social functioning. (shrink)
Alexandre Kojve (1902-1968) was Hegel's most famous interpreter, reading Hegel through the eyes of Marx and Heidegger simultaneously. The result was a wild if not hypnotic mlange of ideas. In this book, Drury reveals the nature of Kojve's Hegelianism and the extraordinary influence it has had on French postmodernists on the left (Raymond Queneau, Georges Bataille, and Michel Foucault) and American postmodernists on the right (Leo Strauss, Allan Bloom, and Francis Fukuyama). According to Drury, Kojve followed Hegel in thinking (...) that reason has triumphed in the course of history, but it is a cold, soulless, instrumental, and uninspired rationalism that has conquered and disenchanted the world. Drury maintains that Kojve's conception of modernity as the fateful triumph of this arid rationality is the cornerstone of postmodern thought. Kojve's picture of the world gives birth to a dark romanticism that manifests itself in a profound nostalgia for what reason has banished - myth, madness, disorder, spontaneity, instinct, passion, and virility. In Drury's view, these ideas romanticize the gratuitous violence and irrationalism that characterize the postmodern world. (shrink)
This book is the first study of the ontological system of Alexander of Aphrodisias (floruit c. 200 AD), famous for his commentaries on the works of Aristotle.
This collection of six essays centers on Professor Koyre;'s great theme: the relative importance of metaphysics and observation, with controlled experiment a kind of marriage between the two. Professor Koyre;'s thesis might be summed up as a claim that when one is seeking to explain the scientific revolution, attention must be concentrated on the philosophical outlook of the scientist and away from speculative theories. At the time of his death, Alexandre Koyre; was a professor at the Ecole Pratique des (...) Hautes Études (Sorbonne) and a memeber of the Institute for Advanced Study in Princeton. (shrink)
This article explores the relation between the concept of symmetry and its formalisms. The standard view among philosophers and physicists is that symmetry is completely formalized by mathematical groups. For some mathematicians however, the groupoid is a competing and more general formalism. An analysis of symmetry that justifies this extension has not been adequately spelled out. After a brief explication of how groups, equivalence, and symmetries classes are related, we show that, while it’s true in some instances that groups are (...) too restrictive, there are other instances for which the standard extension to groupoids is too un restrictive. The connection between groups and equivalence classes, when generalized to groupoids, suggests a middle ground between the two. *Received July 2007. †To contact the authors, please write to: Alexandre Guay, UFR Sciences et Techniques, Université de Bourgogne, 9 Avenue Alain Savary, 21078 Dijon Cedex, France; e‐mail: alexandre.guay@gmail.com ; or to Brian Hepburn, Department of Philosophy, University of British Columbia, 1866 Main Mall E370, Vancouver, BC, Canada V6T 1Z1; e‐mail: brh15@interchange.ubc.ca.

Abstract ‘Prayer’ can be defined as ‘the offering, in public worship or private devotion, of petition, confession, adoration, or thanksgiving to God; also the form of words in which such an offering is made’ (cf. Cohn-Sherbok 2010 ). In addition to this simple definition it could be said that there are different forms of prayer: some are vocal and articulate and others are only mental in nature; some prayers are communal and liturgical and other prayers are spontaneous or at least (...) composed by the one saying the prayer (cf. Stump 1999 ). Accordingly, it is evident that there are manifold intricacies involved in any characterisation of ‘prayer’. In this article my aims are twofold. First, I explore the implications of Martin Buber’s philosophy, particularly of his conception of God as Thou for our understanding of ‘prayer’; second, I will argue that Buber’s understanding of ‘prayer’ as dialogue serves as a way for the individual to seek reconciliation with itself, with others, and with God.

Alexandre Germain | : Le problème du partage des bénéfices liés aux ressources naturelles ne peut faire l’économie de la question territoriale. Cette question est de plus en plus abordée sous l’angle des droits territoriaux sans toutefois reposer sur une théorie générale de la territorialité qui permettrait d’éviter l’écueil de l’ethnocentricité. Nous proposons donc une définition fonctionnaliste de la territorialité permettant de distinguer des territorialités matérielles et idéelles, des territoires formels et fonctionnels, et des conceptions verticale et horizontale du (...) territoire. Ces distinctions nous permettent de formuler une question fondamentale que la philosophie politique a trop peu abordée (et elle offre les outils conceptuels pour y répondre) : comment gérer la concurrence des légitimités territoriales dans un même espace ? | : The problem of how to share the benefits generated from the extraction of natural resources is directly linked to territorial issues. These issues have been increasingly addressed from a perspective of territorial rights without, however, developing a theory of territoriality that would avoid the risk of ethnocentrism. I thus propose a functionalist definition of territoriality that would allow for a distinction between two types of territoriality (material and ideational), two kinds of territories (formal and functional), and two different conceptions of territory (vertical and horizontal). These distinctions lay the groundwork for formulating a fundamental question that has been neglected by political philosophy — how should concurrent territorial legitimacies be managed ? — and provide us with the conceptual tools to tackle it.

Motivationally unconscious (M-unconscious) states are unconscious states that can directly motivate a subject’s behavior and whose unconscious character typically results from a form of repression. The basic argument for M-unconscious states claims that they provide the best explanation to some seemingly non rational behaviors, like akrasia, impulsivity or apparent self-deception. This basic argument has been challenged on theoretical, empirical and conceptual grounds. Drawing on recent works on apparent self-deception and on the ‘cognitive unconscious’ I assess those objections. I argue that (...) (i) even if there is a good theoretical argument for its existence, (ii) most empirical vindications of the M-unconscious miss their target. (iii) As for the conceptual objections, they compel us to modify the classical picture of the M-unconscious. I conclude that M-unconscious states and processes must be affective states and processes that the subject really feels and experiences —and which are in this sense conscious— even though they are not, or not well, cognitively accessible to him. Dual process psychology and the literature on cold-hot empathy gaps partly support the existence of such M-unconscious states. (shrink)
A recent proposal by Norton (2003) to show that a simple Newtonian system can exhibit stochastic acausal behavior by giving rise to spontaneous movements of a mass on the dome of a certain shape is examined. We discuss the physical significance of an often overlooked and yet important Lipschitz condition the violation of which leads to the existence of anomalous nontrivial solutions in this and similar cases. We show that the Lipschitz condition is closely linked with the time reversibility of (...) certain solutions in Newtonian mechanics and the failure to incorporate this condition within Newtonian mechanics may unsurprisingly lead to physically impossible solutions that have no serious metaphysical implications. ‡I thank Steven Savitt of the Philosophy Department at the University of British Columbia for drawing my attention to the Lipschitz condition, and Alexei Cheviakov of the Mathematics Department at the University of British Columbia for useful discussions. †To contact the author, please write to: Department of Philosophy, University of British Columbia, Vancouver, BC, V6T 1Z1, Canada; e-mail: korolev@interchange.ubc.ca.

The purpose of this study was to identify general characteristics attributed to ethical business cultures by executives from a variety of industries. Our research identified five clusters of characteristics: Mission- and Values-Driven, Stakeholder Balance, Leadership Effectiveness, Process Integrity, and Long-term Perspective. We propose that these characteristics be used as a foundation of a comprehensive model that can be engaged to influence operational practices in creating and sustaining an ethical business culture.
In this paper I examine three historically significant readings of the epochal transition from the Middle Ages to the modern world: that provided by Alexandre Koyré in From the Closed World to the Infinite Universe , that of Hans Blumenberg in The Legitimacy of the Modern Age and that of Hannah Arendt in The Human Condition . Each of these readings isolates crucial aspects of the epochal transition which contribute to an understanding of the loss or transformation of traditional (...) measures for knowing and doing consequent upon the shift from the contemplative to the active life. Blumenberg provides a philosophical explanation for the cosmological shift which Koyré describes, while Arendt thematizes the dangers inherent in the loss of an ethical measure which accompanies this transition. Yet both Blumenberg and Arendt conclude that the search for a world-immanent epistemological measure, which would allow us to gauge the adequacy of our descriptions of the world, is not simply a problem for the modern philosopher to address, but rather an impossibility already abandoned in the transition to the modern age. I argue that, on the contrary, such a measure is a requisite of the modern scientific enterprise. (shrink)
The singularity arising from the violation of the Lipschitz condition in the simple Newtonian system proposed recently by Norton (2003) is so fragile as to be completely and irreparably destroyed by slightly relaxing certain (infinite) idealizations pertaining to elastic phenomena in this model. I demonstrate that this is also true for several other Lipschitz-indeterministic systems, which, unlike Norton's example, have no surface curvature singularities. As a result, indeterminism in these systems should rather be viewed as an artefact of certain infinite (...) idealizations essential for these models, depriving them of much of their intended metaphysical import.

Moral status is a vexing topic. Linked for so long to the unending debates about ensoulment and the morality of abortion, it has recently resurfaced in the embryonic stem cell controversy. In this new context, it should benefit from new insights originating in recent scientific advances. We believe that the recently observed capability of somatic cells to return to a pluripotential state (a capability we propose to name 'reversed potency') in a controlled manner requires us to modify the traditional concept (...) of moral status and to consider it as referring not only to intrinsic properties (like 'to possess reason' or 'to be a person'), but also to extrinsic or relational ones.

One objection to enhancement technologies is that they might lead us to live inauthentic lives. Memory modification technologies (MMTs) raise this worry in a particularly acute manner. In this paper I describe four scenarios where the use of MMTs might be said to lead to an inauthentic life. I then undertake to justify that judgment. I review the main existing accounts of authenticity, and present my own version of what I call a “true self” account (intended as a complement, rather (...) than a substitute, to existing accounts). I briefly describe current and prospective MMTs, distinguishing between memory enhancement and memory editing . Moving then to an assessment of the initial scenarios in the light of the accounts previously described, I argue that memory enhancement does not, by its very nature, raise serious concerns about authenticity. The main threat to authenticity posed by MMTs comes, I suggest, from memory editing. Rejecting as inadequate the worries about identity raised by the President’s Council on Bioethics in Beyond Therapy , I argue instead that memory editing can cause us to live an inauthentic life in two main ways: first, by threatening its truthfulness, and secondly, by interfering with our disposition to respond in certain ways to some past events, when we have reasons to respond in such ways. This consideration allows us to justify the charge of inauthenticity in cases where existing accounts fail. It also gives us a significant moral reason not to use MMTs in ways that would lead to such an outcome. (shrink)
The uses of analogy are ancient. It can even be argued that analogical thinking is the most basic cognitive tool humans have to move from the unknown to the known (Gentner et al. 2001). As Olson succinctly puts it, “analogies are useful when it is desired to compare an unfamiliar system with one that is better known” (Olson 1943, p. i). Analogical thinking is thus ubiquitous and found in many texts at least since Homer in Antiquity (Lloyd 1966). For example, (...) it is well known that to explain the properties of atoms, Aristotle compared them to the letters of alphabets, something much better known to his readers than invisible atoms (Hallyn 2000).Many studies have looked at particular uses of analogies among the ..

emantic pathologies of self-reference include the Liar (‘this sentence is false’), the Truth-Teller (‘this sentence is true’) and the Open Pair (‘the neighbouring sentence is false’ ‘the neighbouring sentence is false’). Although they seem like perfectly meaningful declarative sentences, truth value assignment to their uses seems either inconsistent (the Liar) or arbitrary (the Truth-Teller and the Open-Pair). These pathologies thus call for a resolution. I propose such a resolution in terms of relative-truth: the truth value of a pathological sentence use (...) varies with the context of its assessment. It always has a determinate truth value, but this truth value is relative to the context of its assessment. I start by considering a fairly esoteric pathology: the Truth-Teller, that is, sentences which assert nothing but their own truth. I make the case that truth value of a given truth-teller use must in general depend on the context of its assessment, and that one can indeed change its truth value at will. I then show how the notion of assessment-sensitive truth can help us provide solutions to other semantic paradoxes such as the Liar and the Open Pair and that those solutions are immune to revenge problems. I conclude by situating my proposal among the main approaches to the semantic paradoxes, and by drawing a very broad moral about pathological self-reference and intentionality. (shrink)
The elucidation of the gauge principle "is the most pressing problem in current philosophy of physics" Michael Redhead in 2003. This paper argues for two points that contribute to this elucidation in the context of Yang-Mills theories. 1) Yang-Mills theories, including quantum electrodynamics, form a class. They should be interpreted together. To focus on electrodynamics is potentially misleading. 2) The essential role of gauge and BRST symmetries is to provide a local field theory that can be quantized and would be (...) equivalent to the quantization of the non-local reduced theory. If this is correct, the gauge symmetry is significant, not so much because it implies ontological consequences, but because it allows us to quantize theories that we would not be able to quantize otherwise. Thus, in the context of Yang-Mills theories, it is essentially a pragmatic principle. This does not seem to be the case for the gauge symmetry in general relativity. (shrink)
Kant proposes a unique and necessary presupposition of our faculty of judgment. Empirical nature, together with its diverse laws, must be judged as if it were a coherent unity. In a teleological judgment, we add that nature must be judged as if it were purposively designed for our faculty of judgment. In this article, I argue that Kant's insights on reflective teleological judgment - the least commentedupon element of the Critical philosophy - are adopted by Dworkin towards a philosophy of (...) law and adjudication. I claim Dworkin's concept of ‘integrity’ strictly, but tacitly, partakes of the structure of Kant's teleological judgment in its presumption of systematicity in juridical laws and unity of community which designs and abides its own principles. Throughout, I draw on Gilles Deleuze - a philosopher who complains of being ‘against judgment’ and wishes ‘to have done with judgment’ - to critique both the presuppositions and effects of such teleological judgment and the image of law it proposes. Using Deleuze I hope to characterize and criticize the teleological theory of judgment and also fruitfully engage Deleuze with problems of law scarcely addressed either by himself or by commentary. Key Words: Gilles Deleuze • Ronald Dworkin • integrity • judgment • Immanuel Kant • law • principle • teleology. (shrink)

Alexandre Koyré ha scritto che Newton e la scienza che è seguita sono responsabili di aver spaccato il mondo in due: da un lato il «mondo delle qualità e delle percezioni sensibili», dall’altra il «mondo della quantità e della geometria reificata». Un confronto anche sommario tra i fatti che risultano veri per il senso comune e falsi nell’immagine scientifica (o viceversa) sembra dar ragione a Koyré e ai tanti filosofi che hanno adottato la dicotomia. Ma si tratta davvero (...) di una dicotomia reale? Il mondo del senso comune è davvero un «altro mondo» rispetto a quello delle scienze fisiche? Nelle pagine che seguono cercheremo di articolare una risposta negativa a queste domande. (shrink)
A recent proposal to solve the halting problem with the quantum adiabatic algorithm is criticized and found wanting. Contrary to other physical hypercomputers, where one believes that a physical process “computes” a (recursive-theoretic) non-computable function simply because one believes the physical theory that presumably governs or describes such process, believing the theory (i.e., quantum mechanics) in the case of the quantum adiabatic “hypercomputer” is tantamount to acknowledging that the hypercomputer cannot perform its task.
This study focuses on comparison of perceptions of ethical business cultures in large business organizations from four largest emerging economies, commonly referred to as the BRICs (Brazil, Russia, India, and China), and from the US.

The study found significant differences among BRIC countries, with respondents from India and Brazil providing more favorable assessments of ethical cultures of their organizations than respondents from China and (...) Russia. Overall, highest mean scores were provided by respondents from India, the US, and Brazil. There were significant similarities in ratings between the US and Brazil. (shrink)
