The justification of Bayes' rule by cognitive rationality principles is undertaken by extending the propositional axiom systems usually proposed in two contexts of belief change: revising and updating. Probabilistic belief change axioms are introduced, either by direct transcription of the set-theoretic ones, or in a stronger way but nevertheless in the spirit of the underlying propositional principles. Weak revising axioms are shown to be satisfied by a General Conditioning rule, extending Bayes' rule but also compatible with others, and weak updating (...) axioms by a General Imaging rule, extending Lewis' rule. Strong axioms (equivalent to the Miller–Popper axiom system) are necessary to justify Bayes' rule in a revising context, and justify in fact an extended Bayes' rule which applies, even if the message has zero probability.

Despite its importance in various fields, analogical reasoning has not yet received a unified formal representation. Our contribution proposes a general scheme of inference that is compatible with different types of logic (deductive, probabilistic, non-monotonic). Firstly, analogical assessment precisely defines the similarity of two objects according to their properties, in a relative rather than absolute way. Secondly, analogical inference transfers a new property from one object to a similar one, thanks to an over-hypothesis linking two sets of properties. The belief (...) strength in the conclusion is then directly related to the belief strength in this meta-hypothesis. (shrink)

Abduction was first introduced in the epistemological context of scientific discovery. It was more recently analyzed in artificial intelligence, especially with respect to diagnosis analysis or ordinary reasoning. These two fields share a common view of abduction as a general process of hypotheses formation. More precisely, abduction is conceived as a kind of reverse explanation where a hypothesis H can be abduced from events E if H is a good explanation of E. The paper surveys four known schemes for abduction (...) that can be used in both fields. Its first contribution is a taxonomy of these schemes according to a common semantic framework based on belief revision. Its second contribution is to produce, for each non-trivial scheme, a representation theorem linking its semantic framework to a set of postulates. Its third contribution is to present semantic and axiomatic arguments in favor of one of these schemes, ordered abduction, which has never been vindicated in the literature. (shrink)

Two main schemes explain how a system adapts to its environment. Evolutionary models are grounded on three usual processes (variation, transmission, selection) acting at the population level. Learning models are concerned with the endogenous search for a better performance at the individual level. The first ones were initially favored by biology and the second well illustrated by game theory. The article examines first how game theory went to evolution and how biology later considered learning. It shows some examples of a (...) hybrid use of models of each type. It finally proposes a common framework for both types of models. (shrink)

RésuméEn dépit de son importance dans divers domaines, le raisonnement analogique n'a pas encore reçu de représentation formelle unifiée. Notre contribution propose un schéma d'inférence général, compatible avec différentes logiques (déductive, probabiliste, non monotone). Premièrement, un énoncé analogique définit précisément la similarité entre deux objets en fonction de leurs propriétés, de façon relative et non absolue. Deuxièmement, une inférence analogique transfère une propriété nouvelle d'un objet à un objet similaire, grâce à une hypothèse d'arrière-plan qui relie deux ensembles de propriétés. (...) Le degré de croyance dans la conclusion est alors directement relié au degré de croyance dans cette méta-hypothèse. (shrink)

L’article propose d’abord une version simplifiée d’une ontologie universelle, conçue comme un cadre général de description du monde matériel et mental. Il examine les notions d’entité, de propriété, de relation et de temporalité et leurs développements conjoints en termes de rapport entre les parties et le tout ou encore d’émergence d’une entité nouvelle. Il illustre ensuite les principes précédents en ce qui concerne la science économique, dont les entités de base sont les agents, les biens et les institutions. Il insiste (...) sur le couplage que cette dernière réalise entre leurs propriétés physiques ou psychologiques et le raisonnement qu’elle propose en termes d’équilibre et plus récemment d’apprentissage.

The Sleeping Beauty problem is presented in a formalized framework which summarizes the underlying probability structure. The two rival solutions proposed by Elga and Lewis differ by a single parameter concerning her prior probability. They can be supported by considering, respectively, that Sleeping Beauty is “fuzzy-minded” and “blank-minded”, the first interpretation being more natural than the second. The traditional absent -minded driver problem is reinterpreted in this framework and sustains Elga’s solution.

The paper studies a specific adaptive learning rule when each player faces a unidimensional strategy set. The rule states that a player keeps on incrementing her strategy in the same direction if her utility increased and reverses direction if it decreased.

We study in general the (...) behavior of the system in the interior as well as on the borders of the strategy space. We then describe the system asymptotic behavior for symmetric, zero-sum, and twin games. Original patterns emerge. For instance, for the “prisoner’s dilemma” with symmetric initial conditions, the system goes directly to the symmetric Pareto optimum. For “matching pennies,” the system follows slowly expanding cycles around the mixed strategy equilibrium. (shrink)

Conscious experience is one of the most difficult and thorny problems in psychological science. Its study has been neglected for many years, either because it was thought to be too difficult, or because the relevant evidence was thought to be poor. Bernard Baars suggests a way to specify empirical constraints on a theory of consciousness by contrasting well-established conscious phenomena - such as stimulus representations known to be attended, perceptual, and informative - with closely comparable unconscious ones - such (...) as stimulus representations known to be preperceptual, unattended, or habituated. Adducing data to show that consciousness is associated with a kind of global workplace in the nervous system, and that several brain structures are known to behave in accordance with his theory, Baars helps to clarify many difficult problems.

Descartes has often been called the 'father of modern philosophy'. His attempts to find foundations for knowledge, and to reconcile the existence of the soul with the emerging science of his time, are among the most influential and widely studied in the history of philosophy. This is a classic and challenging introduction to Descartes by one of the most distinguished modern philosophers. Bernard Williams not only analyzes Descartes' project of founding knowledge on certainty, but uncovers the philosophical motives for (...) his search. With acute insight, he demonstrates how Descartes' _Meditations _are not merely a description but the very enactment of philosophical thought and discovery. Williams covers all of the key areas of Descartes' thought, including God, the will, the possibility of knowledge, and the mind and its place in nature. He also makes profound contributions to the theory of knowledge, metaphysics and philosophy generally. With a new foreword by John Cottingham. (shrink)

In Morality Bernard Williams confronts the problems of writing moral philosophy, and offers a stimulating alternative to more systematic accounts which seem nevertheless to have left all the important issues somewhere off the page.

This book presents the thought of the Kyoto School in comparison with continental philosophers better known in the West and addresses the affiliation of some of its members with the militarism of the 1930s and 1940s.

In the aftermath of the First World War, the poet Paul Valéry wrote of a "crisis of spirit", brought about by the instrumentalization of knowledge and the destructive subordination of culture to profit. Recent events demonstrate all too clearly that the stock of mind, or spirit, continues to fall. The economy is toxically organized around the pursuit of short-term gain, supported by an infantilizing, dumbed-down media. Advertising technologies make relentless demands on our attention, reducing us to idiotic beasts, no longer (...) capable of living. Spiralling rates of mental illness show that the fragile life of the mind is at breaking point. Underlying these multiple symptoms is consumer capitalism, which systematically immiserates those whom it purports to liberate. Returning to Marxʹs theory, Stiegler argues that consumerism marks a new stage in the history of proletarianization. It is no longer just labour that is exploited, pushed below the limits of subsistence, but the desire that is characteristic of human spirit. The cure to this malaise is to be found in what Stiegler calls a "pharmacology of the spirit". Here, pharmacology has nothing to do with the chemical supplements developed by the pharmaceutical industry. The pharmakon, defined as both cure and poison, refers to the technical objects through which we open ourselves to new futures, and thereby create the spirit that makes us human. By reference to a range of figures, from Socrates, Simondon and Derrida to the child psychoanalyst Donald Winnicott, Stiegler shows that technics are both the cause of our suffering and also what makes life worth living. -- Publisher description.

Die "Paradoxien des Unendlichen" sind ein Klassiker der Philosophie der Mathematik und zugleich eine gute Einführung in das Denken des "Urgroßvaters" der analytischen Philosophie. Das Unendliche - seit jeher ein Faszinosum für die philosophische Reflexion - wurde in der Zeit nach der Grundlegung der Analysis durch Leibniz und Newton in der Mathematik zunächst als Problem betrachtet, das sich nicht vollkommen widerspruchsfrei behandeln lässt. Bernard Bolzano, der heute als "Urgroßvater der analytischen Philosophie" (Michael Dummett) gilt, zeigt in diesem klassisch gewordenen (...) Text jedoch, dass es beim Nachdenken über das Unendliche, sofern man begrifflich differenziert argumentiert und klare Definitionen zugrunde legt, keine echten Widersprüche gibt und sich die "Paradoxien des Unendlichen" auflösen lassen. Bolzano setzt sich zunächst mit den Unendlichkeitsbegriffen der Mathematik und der (idealistisch geprägten) Philosophie seiner Zeit auseinander, bevor er sich Schritt für Schritt die analytischen Grundlagen einer konsistenten Theorie des Unendlichen erarbeitet. Bereits einige Jahrzehnte vor Georg Cantors bis heute maßgeblicher mathematischer Unendlichkeitsdefinition gelingt Bolzano mit diesem Werk, dessen logische Klarheit und dessen Grad an philosophischer Durchdachtheit bis heute Beispielcharakter haben, die Rehabilitation des Unendlichen für die Philosophie der Mathematik. Die "Paradoxien des Unendlichen" wurden zuerst 1851 aus dem Nachlass herausgegeben. Diese Neuausgabe beruht auf dem der Erstausgabe zugrundeliegenden Manuskript. (shrink)

Epistemic decolonization, in its various conceptual formulations and presentations, could be taken to hold promise for either the completion of the anti-colonial struggle or the self-re-discovery of the formerly colonized and oppressed. In Africa this project has had a long history as both a counter to hegemonic histories of claimed Western epistemological superiority as well as theories of racism and racist practices against black people of African descent. What is not entirely clear are the precise achievements of decolonial thought and (...) practice. I interrogate the relevance, use and continuation of decoloniality as a genre of thought and practice on the African continent against the background of the perennial problems of material underdevelopment and stifled political spaces that render the supposed beneficiaries of decolonization hopeless subjects who continue to be disempowered and oppressed in their own home. This interrogation is to be carried alongside another inquiry aimed at evaluating the achievements of African philosophy as a form of epistemic decolonization. If African philosophy is a form of decolonization, as it should be, it should be able to clearly demonstrate its achievements and how they have had an effect on broader goals of decolonizing and empowering inhabitants of the African continent.

El presente artículo es una aproximación exploratoria a las redes de cuidados que están proliferando entre los vecinos de las grandes ciudades españolas como una reacción de la sociedad civil para acometer la crisis ocasionada por la COVID-19, que afecta actualmente a los hogares estructuralmente más vulnerables. Los efectos de la emergencia alimentaria sobrevenida como consecuencia de la pandemia tienen un fuerte componente socio-espacial, y ponen en cuestión el modelo de bienestar de la ciudad de Madrid, el caso en que (...) se centra el estudio. Examinaremos los orígenes de las redes de cuidados en la ciudad, su vinculación con el movimiento vecinal, y los efectos del cambio en el modelo de ciudad entre gobiernos conservadores y neo municipalistas. Analizaremos la estructura de las redes de cuidados, su actuación, y especialmente el posible papel de sus integrantes como actores políticos en la ciudad neoliberal, desde tres enfoques teóricos distintos: el de los movimientos sociales, el de la innovación social y el de la gobernanza urbana.

Peu de philosophes contemporains choisissent de faire vivre leurs outils critiques grâce au terreau d'une association, d'un collectif. C'est le cas de Bernard Stiegler, qui a fondé Ars Industrialis en 2005. Le manifeste de l'association, Réenchanter le monde (Flammarion, 2005 ; 7400 ventes en Champs), devait connaître un grand retentissement. Depuis, les travaux et contributions fleurissent (de l'économiste André Gréau au comédien Robin Renucci, en passant par les spécialistes des digital studies), et Ars Industrialis franchit un cap en s'associant (...) à des collectivités locales (Nantes) ou en nouant des partenariats internationaux (Grande-Bretagne, Allemagne). Cet ouvrage fournit une synthèse de tous ces travaux en proposant un vocabulaire philosophique à la fois ambitieux et accessible. Qu'est-ce le marketing - le psychopouvoir - et pourquoi est-il un des dangers majeurs de notre époque? En quoi la technique influence-t-elle des fonctions aussi capitales que la mémoire ou l'écriture? Quelle nouvelle vision de l'éducation devons-nous mettre à jour depuis l'avènement du numérique? Que sont la bêtise et l'intelligence? Comment aider la transformation de citoyens passifs et débordés en amateurs, acteurs et membres d'une communauté de goûts et de savoirs? Faire attention propose, dans ces courts essais-définitions, le manifeste d'une époque charnière qui voit définitivement s'éloigner le monde ancien, tout en souhaitant mettre les outils de l'extrême contemporain au service d'un nouvel humanisme.

Boucs émissaires, violences sacrificielles, désir mimétique, autant de thèmes que René Girard (1923-2015) n'a cessé d'explorer et qui sont devenus des ressources essentielles pour notre compréhension des sociétés. L'anthropologie mimétique, dont il a posé les bases, a en effet eu des échos multiples dans les sciences humaines et les religions. Avec ce livre, Bernard Perret offre une présentation éloquente de ce vaste chantier théorique. Il éclaire notamment la fonction et la signification de la violence dans les rapports humains, des (...) origines à nos jours, tout en explorant les liens et les différences entre la pensée de Girard et celle d'autres grands auteurs du XXe siècle (Lacan, Lévi-Strauss, Mauss...). Le lien particulier de Girard aux Écritures juives et chrétiennes, le sens à la fois novateur et controversé qu'il donne à la passion et à la mort du Christ, ne sont pas éludés, tout comme sa vision apocalyptique du politique. En exposant la cohérence profonde et la fécondité d'une pensée majeure de notre temps, ce livre permet de ressaisir tous les débats passionnants auxquels elle a donné et donne toujours lieu."--Page 4 of cover.

The paper examines the view that Nietzsche's perspectivism about practical judgments, understood as a form of internalism about practical reasons, implies that any legitimate criticism of judgments emanating from a foreign perspective must be in terms that are internal to this perspective. Insofar as it is thought to be motivated by certain general theoretical strictures of perspectivism, this view is incoherent. The paper argues that, on the contrary Nietzsche's recourse to a strategy of internal criticism is motivated by his own (...) particular commitment to preserving the freedom of spirit of his interlocutors. The paper concludes with a discussion of how freedom of spirit is preserved by internal criticism, and how the nature of freedom of spirit affects the particular form such criticism will assume.

Time is analyzed as being those processes by which a system notes the processes which comprise its own existence. The directionality of time is given by the concepts, past, present, and future. To understand the meaning of these concepts, a set of experiments was carried out with four male subjects in which areas of time were expanded or ablated by means of post-hypnotic suggestions. These operations were carried out singly or in combination. The data suggest that the present is primarily (...) associated with stimulus input, the past with the criteria for defining that input as well as the development of response inhibitions and the future with the directionality of that input. Marked personality changes which range from the occurence of catatonic-like states to obsessive types of reaction and manic-like reactions are associated with different combinations of time alterations. Some of the changes are in accord with the serialist position on time of J. W. Dunne. The concept of death is very important both with regard to one’s view of time and how one lives. While it is important to live in the present, the present has no meaning without at least a past or a future. Implications of these findings for psychopathology in general and schizophrenia in particular are considered. (shrink)

1ere edition: Aubier, 1999 En assignant pour tache a la philosophie de surmonter la contingence, Hegel accomplit un geste original et difficile. Original parce qu'il s'ecarte aussi bien des rationalismes qui pensent n'en avoir fini avec le contingent que lorsqu'ils l'ont ramene au necessaire, que des penseurs qui estiment que reconnaitre la contingence, c'est y voir le tout autre de la raison. Hegel ne prone ni le regne de la necessite ni la capitulation devant l'absurde, mais une philosophie de la (...) liberte. Difficile, parce que, en decidant de penser ensemble et la consistance et la rationalite du contingent, Hegel doit a la fois reconnaitre ce qu'il appelle son droit monstrueux et au moment meme ou la raison avoue ses limites devant une contingence sans regle et sans frein ne jamais renoncer a l'exigence de dire le sens de cette limitation meme. A travers cette epreuve de la contingence, l'ouvrage tente d'offrir une interpretation d'ensemble du systeme aussi attentive a la lettre des textes qu'attachee a mettre en lumiere les apories que la philosophie hegelienne rencontre ou engendre.

Paris, 1943. In a flash, a book is published that will shape post-war Europe like none other. Jean-Paul Sartre’s Being and Nothingness discloses utterly new insights about human freedom, about feelings such as shame and desire, and about death. The new edition of the renowned book of commentary on the magnum opus of French existentialism opens access to the work through the latest state of research.

La science est un modèle qui mime dans l'abstrait le comportement de la nature. Créations du chercheur, les théories pour un fait donné peuvent être multiples et chacune valide. La science a des lois, la nature n'en a pas. L'ordre de la nature, c'est le chercheur qui l'y met. L'esprit, façonnant un amorphe premier, participe à la mise en forme de la nature produisant le Réel "en nous". Celle-ci, réciproquement, modèle l'esprit. De ce fait, l'univers n'existerait plus si l'homme disparaissait...

A bold new interpretation of Aristotelian thought is central to Bernard Yack's provocative new book. He shows that for Aristotle, community is a conflict-ridden fact of everyday life, as well as an ideal of social harmony and integration. From political justice and the rule of law to class struggle and moral conflict, Yack maintains that Aristotle intended to explain the conditions of everyday political life, not just, as most commentators assume, to represent the hypothetical achievements of an idealistic "best (...) regime." By showing how Aristotelian ideas can provide new insight into our own political life, Yack makes a valuable contribution to contemporary discourse and debate. His work will excite interest among a wide range of social, moral, and political theorists. (shrink)
