"Mille Plateaux (Paris, Éditions de Minuit, 1980) est le second des deux volumes ayant pour sous-titre Capitalisme et schizophrénie issu de la collaboration entre le philosophe Gilles Deleuze et le philosophe et psychanalyste Félix Guattari. Cet ouvrage continue à explorer par des voies inédites - en s'attaquant notamment à une série d'erreurs afférentes selon les auteurs à l'arborescence, à l'État, au langage... - la question déjà avancée dans L'Anti-Œdipe (premier volume) d'une ontologie révolutionnaire des devenirs ("presque imperceptibles") qui ne (...) cessent de défaire l'histoire des identités ("primauté des lignes de fuite") et de produire des "coups" imprévisibles au sociologue et au militant. Sans doute le livre politique de Deleuze et Guattari le plus important, grâce à sa conception originale du pluralisme (l'individu n'y est pas conçu comme fondement de l'organisation sociale : les subjectivités sociales sont toujours au-dessus ou en dessous du niveau de l'individu, composant et décomposant des collectivités de toutes sortes)"--Wikipedia = Mille Plateaux (Paris: Editions de Minuit, 1980) is the second of two volumes which comes in the series of Capitalism and Schizophrenia is a result of collaboration between the philosopher Gilles Deleuze and Felix Guattari, philosopher and psychoanalyst. This book continues to explore new paths - including addressing a series of errors by the authors related to the tree, the state, the language... - that are already dealt with in Anti-Oedipus (first volume) of an ontology of revolutionary futures; the latter continues to unravel the history of identities ("primacy of lines of flight") and produce "coups" unforeseeable to the sociologist and activist. No doubt the political book of Deleuze and Guattari's is the most important, with its original conception of pluralism (the individual is not conceived as the foundation of social organization: social subjectivities are always above or below of the individual level, composing and decomposing communities of all kinds).".

Deleuze and Guattari differentiate between philosophy, science, and the arts - seeing each as a means of confronting chaos - and challenge the common view that philosophy is an extension of logic. The authors also discuss the similarities and distinctions between creative and philosophical writing. Fresh anecdotes from the history of philosophy illuminate this book, along with engaging discussions of composers, painters, writers, and architects.

Considered one of the most important works of one of France's foremost philosophers, and long-awaited in English, "The Logic Of Sense" is an essay in literary and psychoanalytic theory, and philosophy, and helps to illuminate such works as "Anti-Oedipus".

Examines the philosophical foundations of Foucault's writings and discusses his views on knowledge, punishment, power, and subjectivation.

Examines the philosophy of Henri Bergson, explains his concepts of duration, memory, and elan vital, and discusses the influence of science on Bergson.

For those not yet acquainted with the work of this philosopher, this book provides a point of entry to his complex theories. For those more familiar with Deleuze, this collection should be useful in broadening their understanding of this influential thinker's journey in search of knowledge.

Il faudrait que le dialogue se fasse, non pas entre des personnes, mais entre les lignes, entre des chapitres ou des parties de chapitre. Ce seraient les vrais personnages. Perdre la mémoire : il faudrait plutôt dresser des " blocs ", les faire flotter. Un bloc d'enfance n'est pas un souvenir d'enfant. Un bloc nous accompagne, est toujours anonyme et contemporain, et fonctionne dans le présent - Oublier l'histoire : la question des devenirs, et de leur géographie. Un devenir-révolutionnaire est (...) plus important que l'avenir ou le passé de la révolution. Un devenir-femme, un devenir-animal sont plus importants que la différence des sexes et des règnes - Ne pas " faire le point " : plutôt tracer des lignes. Les lignes n'ont pas d'origine, et poussent par le milieu. On ne fait jamais table rase, on est toujours au milieu de quelque chose, comme l'herbe. Plus on prend le monde là où il est, plus on a de chance de le changer... Se séparer de l'appareil d'Etat et de tout système qui le prend pour modèle ou veut le conquérir : la présence diffuse de machines de guerre irréductibles au modèle d'Etat, toute une histoire populaire qui n'a pas été recueillie, un nomadisme même immobile. Devenir ou re-devenir marxiste : aucune analyse n'est possible si elle ne porte aussi sur les mécanismes industriels et surtout financiers dans un champ social. Non pas suprême instance, mais lignes, et régimes de signes, qui s'enchaînent avec les autres, et dont les flottaisons s'agencent avec d'autres flux. (shrink)

La philosophie n'est ni contemplation, ni réflexion, ni communication. Elle est l'activité qui crée les concepts. Comment se distingue-t-elle de ses rivales, qui prétendent nous fournir en concepts? La philosophie doit nous dire quelle est la nature créative du concept, et quels en sont les concomitants : la pure immanence, le plan d'immanence, et les personnages conceptuels. Par là, la philosophie se distingue de la science et de la logique. Celles-ci n'opèrent pas par concepts, mais par fonctions, sur un plan (...) de référence et avec des observateurs partiels. L'art opère par percepts et affects, sur un plan de composition avec des figures esthétiques. La philosophie n'est pas interdisciplinaire, elle est elle-même une discipline entière qui entre en résonance avec la science et avec l'art, comme ceux-ci avec elle : trouver le concept d'une fonction, etc. C'est que les trois plans sont les trois manières dont le cerveau recoupe le chaos, et l'affronte. Ce sont les Chaoïdes. La pensée ne se constitue que dans ce rapport où elle risque toujours de sombrer. (shrink)

"Durée, mémoire, élan vital marquent les grandes étapes de la philosophie bergsonienne. L'objet de ce livre est la détermination du rapport entre ces trois notions et du progrès qu'elles impliquent. L'intuition est la méthode du bergsonisme et l'intuition telle qu'il l'entend méthodiquement suppose la durée". Analysant le travail philosophique de Bergson, Gilles Deleuze s'interroge sur la possibilité d'établir une méthode philosophique rigoureuse et précise, fondée sur l'intuition et sur la manière dont Bergson en a élaboré les règles pour construire (...) sa philosophie. Il s'attache à étudier les relations établies tout au long de l'oeuvre, entre les trois concepts majeurs de la philosophie bergsonienne : la durée comme donnée immédiate, la mémoire comme existence virtuelle et l'élan vital comme mouvement de la différenciation.

A playful, personal, and profound interview with Gilles Deleuze, covering topics from “Animal” to “Zigzag.” Although Gilles Deleuze never wanted a film to be made about him, he agreed to Claire Parnet's proposal to film a series of conversations in which each letter of the alphabet would evoke a word: From A to Z. These DVDs, elegantly transtlated and subtitled in English, make these conversations available for English-speaking audiences? for the first time. In dialogue with Parnet, the philosopher (...) exhibited the modest and thrilling transparency that his seminal works reveal. The sessions were taped when Deleuze was already terminally ill; he and Parnet agreed that the film would not be shown publicly until after his death. The awareness of mortality floats through the dialogues, making them not just intellectually stimulating but also emotionally engaging. Because Parnet knew Deleuze so well, she was able to draw him out—as no one else had—to what might be the 1001st plateau: a place of brilliance, rigor, and charm. In “A as in Animal,” for example, Deleuze vents his hatred of pets: “A bark,” he declares, “really seems to me the stupidest cry.” Instead, he praises the tick: “... in a nature teeming with life, [the tick] extracts three things”: light, smell, and touch. This, he claims, in a sense is philosophy. “And that is your life's dream?” Parnet wryly asks. “That's what constitutes a world,” he replies. For Deleuze, doing philosophy meant not just creating concepts but living a life in philosophy. Gilles Deleuze from A to Z presents the mind of a great philosopher at work. (shrink)

Translated and with an Introduction by Daniel W. Smith Afterword by Tom Conley Gilles Deleuze had several paintings by Francis Bacon hanging in his Paris apartment, and the painter’s method and style as well as his motifs of seriality, difference, and repetition influenced Deleuze’s work. This first English translation shows us one of the most original and important French philosophers of the twentieth century in intimate confrontation with one of that century’s most original and important painters. In considering Bacon, (...) Deleuze offers implicit and explicit insights into the origins and development of his own philosophical and aesthetic ideas, ideas that represent a turning point in his intellectual trajectory. First published in French in 1981, _Francis Bacon_ has come to be recognized as one of Deleuze’s most significant texts in aesthetics. Anticipating his work on cinema, the baroque, and literary criticism, the book can be read not only as a study of Bacon’s paintings but also as a crucial text within Deleuze’s broader philosophy of art. In it, Deleuze creates a series of philosophical concepts, each of which relates to a particular aspect of Bacon’s paintings but at the same time finds a place in the “general logic of sensation.” Illuminating Bacon’s paintings, the nonrational logic of sensation, and the act of painting itself, this work—presented in lucid and nuanced translation—also points beyond painting toward connections with other arts such as music, cinema, and literature. _Francis Bacon_ is an indispensable entry point into the conceptual proliferation of Deleuze’s philosophy as a whole. Gilles Deleuze was professor of philosophy at the University of Paris, Vincennes–St. Denis. He coauthored _Anti-Oedipus_ and _A Thousand Plateaus_ with Félix Guattari. These works, as well as _Cinema 1, Cinema 2, The Fold, Proust and Signs_, and others, are published in English by Minnesota. Daniel W. Smith teaches in the Department of Philosophy at Purdue University. (shrink)

In this extraordinary work Gilles Deleuze reflects on one of the figures of the past who has most influenced his own sweeping reconfiguration of the tasks of philosophy.

Conceptual integration—“blending”—is a general cognitive operation on a par with analogy, recursion, mental modeling, conceptual categorization, and framing. It serves a variety of cognitive purposes. It is dynamic, supple, and active in the moment of thinking. It yields products that frequently become entrenched in conceptual structure and grammar, and it often performs new work on its previously entrenched products as inputs. Blending is easy to detect in spectacular cases but it is for the most part a routine, workaday process that (...) escapes detection except on technical analysis. It is not reserved for special purposes, and is not costly.In blending, structure from input mental spaces is projected to a separate, “blended” mental space. The projection is selective. Through completion and elaboration, the blend develops structure not provided by the inputs. Inferences, arguments, and ideas developed in the blend can have effect in cognition, leading us to modify the initial inputs and to change our view of the corresponding situations.Blending operates according to a set of uniform structural and dynamic principles. It additionally observes a set of optimality principles. (shrink)

Texts and interviews from the period that saw the publication of Deleuze's major works. People tend to confuse winning freedom with conversion to capitalism. It is doubtful that the joys of capitalism are enough to free peoples.... The American “revolution” failed long ago, long before the Soviet one. Revolutionary situations and attempts are born of capitalism itself and will not soon disappear, alas. Philosophy remains tied to a revolutionary becoming that is not to be confused with the history of revolutions.—from (...) Two Regimes of Madness Covering the last twenty years of Gilles Deleuze's life, the texts and interviews gathered in this volume complete those collected in Desert Islands and Other Texts. This period saw the publication of his major works: A Thousand Plateaus, Cinema I: Image-Movement, Cinema II: Image-Time, all leading through language, concept and art to What is Philosophy?. Two Regimes of Madness also documents Deleuze's increasing involvement with politics. Both volumes were conceived by the author himself and will be his last. Michel Foucault famously wrote: “One day, perhaps, this century will be Deleuzian.” This book provides a prodigious entry into the work of the most important philosopher of our time. Unlike Foucault, Deleuze never stopped digging further into the same furrow. Concepts for him came from life. He was a vitalist and remained one to the last. This volume restores the full text of the original French edition. (shrink)

Le pli a toujours existé dans les arts, mais le propre du Baroque est de porter le pli à l'infini. Si la philosophie de Leibniz est baroque par excellence, c'est parce que tout se plie, se déplie, se replie. Sa thèse la plus célèbre est celle de l'âme comme " monade " sans porte ni fenêtre, qui tire d'un sombre fond toutes ses perceptions claires : elle ne peut se confondre que par analogie avec l'intérieur d'une chapelle baroque, de marbre (...) noir, où la lumière n'arrive que par des ouvertures imperceptibles à l'observateur du dedans : aussi l'âme est-elle pleine de plis obscurs. Pour découvrir un néo-Baroque moderne, il suffit de suivre l'histoire du pli infini dans tous les arts : " pli selon pli " avec la poésie de Mallarmé et le roman de Proust, mais aussi l'œuvre de Michaux, la musique de Boulez, la peinture de Hantaï. Et ce néoleibnizianisme n'a cessé d'inspirer la philosophie. (shrink)

Le livre que j'ai fait, ce n'est pas l'histoire de la philosophie, c'est un livre que j'aurai voulu faire avec0 (Michel Foucault), avec l'idée que j'ai de lui et mon admiration pour lui. Si ce livre avait pu avoir une valeur poétique, ç'aurait été ce que les poètes appellent un "tombeau". Gilles Deleuze, Pourparlers.

Ce n'est pas le moindre des mérites de la pensée de Gilles Deleuze que de penser l'individuation de l'art sous le signe d'une logique du sensible où esthétique et clinique sont en présuppositions réciproques. En explorant les coupes et les tensions névralgiques qui irriguent cette logique, les études ici réunies trouvent leur commune impulsion dans le souci de remettre en chantier la cartographie deleuzienne des arts, et d'interroger les écarts et les résonances internes qui l'animent. La spécificité de cet (...) ouvrage est de croiser non seulement des lectures d'éminents spécialistes de la philosophie de Gilles Deleuze, venant sonder à nouveaux frais son rapport singulier aux variations du sensible, mais aussi des contributions de théoriciens de la théorie littéraire, de la musique, du cinéma ou encore de l'histoire de l'art, réinterrogeant depuis leur point de vue une pensée de la création dont on ne mesure pas encore pleinement la puissance et la fécondité.

La tesis central de este artículo es que “los centros de encierro” disciplinarios descritas por Foucault: “cárcel, hospital, fábrica, escuela, familia, atraviesan una crisis generalizada”. Vivimos la decadencia de la “sociedad disciplinaria”, que fue “la sucesora de las sociedades de soberanía”, cuyos fines y funciones eran completamente distintos. Estas surgieron en los siglos XVII y XVIII hasta mediados del XX, y fueron el tema central de las investigaciones de Foucault. La sociedad actual es denominada como “sociedad de control” y éste (...) se ejerce fluidamente en espacios abiertos, en forma desterritorializada, mediante los psico-fármacos, el consumo televisivo, el marketing, el endeudamiento privado, el consumo, entre otras modalidades. Lo esencial en ellas son las cifras fluctuantes e intercambiables como las que muestran el valor de una moneda en las otras, el movimiento incesante del surf que sustituye los deportes lentos y estratégicos como el box. Las fábricas son reemplazadas por las empresas, que son formaciones dúctiles y cambiantes, las máquinas simples por sistemas computarizados de producción y control. La in-dividualidad es sustituida por “divuales” externos, informatizados e informatizables, que se desplazan en un espacio virtual. (shrink)

Contemporary experimental research has emphasised the role of centrally generated signals arising from premotor areas in voluntary muscular force perception. It is therefore generally accepted that judgements of force are based on a central sense, known as the sense of effort, rather than on a sense of intra-muscular tension. Interestingly, the concept of effort is also present in the classical philosophy: to the French philosopher Maine de Biran [Maine de Biran . Mémoire sur la décomposition de la pensée , Vrin, (...) Paris ], the sense of effort is the fundamental component of self-experience, the landmark of the exercise of the will. In the present review, after a presentation of the nature and neurophysiological bases of effort sensation, we will examine its possible involvement in the neurocognitive process of agency. We will further focus on delusions of alien control in schizophrenic patients. Experimental data suggest that these patients have an abnormal awareness of effort caused by cerebral anomalies in the frontal and parietal lobes. (shrink)

Most models of response time (RT) in elementary cognitive tasks implicitly assume that the speed-accuracy trade-off is continuous: When payoffs or instructions gradually increase the level of speed stress, people are assumed to gradually sacrifice response accuracy in exchange for gradual increases in response speed. This trade-off presumably operates over the entire range from accurate but slow responding to fast but chance-level responding (i.e., guessing). In this article, we challenge the assumption of continuity and propose a phase transition model for (...) RTs and accuracy. Analogous to the fast guess model (Ollman, 1966), our model postulates two modes of processing: a guess mode and a stimulus-controlled mode. From catastrophe theory, we derive two important predictions that allow us to test our model against the fast guess model and against the popular class of sequential sampling models. The first prediction—hysteresis in the transitions between guessing and stimulus-controlled behavior—was confirmed in an experiment that gradually changed the reward for speed versus accuracy. The second prediction—bimodal RT distributions—was confirmed in an experiment that required participants to respond in a way that is intermediate between guessing and accurate responding. (shrink)

Perhaps the question “What is philosophy?” can only be posed late in life, when old age has come, and with it the time to speak in concrete terms. It is a question one poses when one no longer has anything to ask for, but its consequences can be considerable. One was asking the question before, one never ceased asking it, but it was too artificial, too abstract; one expounded and dominated the question, more than being grabbed by it. There are (...) cases in which old age bestows not an eternal youth, but on the contrary a sovereign freedom, a pure necessity where one enjoys a moment of grace between life and death, and where all the parts of the machine combine to dispatch into the future a trait that traverses the ages: Turner, Monet, Matisse. The elderly Turner acquired or conquered the right to lead painting down a deserted path from which there was no return, and that was no longer distinguishable from a final question. In the same way, in philosophy, Kant’s Critique of Judgment is a work of old age, a wild work from which descendants will never cease to flow.We cannot lay claim to such a status. The time has simply come for us to ask what philosophy is. And we have never ceased to do this in the past, and we already had the response, which has not varied: philosophy is the art of forming, inventing, and fabricating concepts. But it was not only necessary for the response to take note of the question; it also had to determine a time, an occasion, the circumstances, the landscapes and personae, the conditions and unknowns of the question. One had to be able to pose the question “between friends” as a confidence or a trust, or else, faced with an enemy, as a challenge, and at the same time one had to reach that moment, between dog and wolf, when one mistrusts even the friend. Gilles Deleuze was professor of philosophy at the University of Paris VIII, Vincennes-St.-Denis, until his retirement in 1987. Among his books translated into English are the two-volume Capitalism and Schizophrenia , the two-volume Cinema , The Logic of Sense , and Expressionism in Philosophy: Spinoza . Daniel W.

This article presents a formal ontology which accounts for the general nature of artefacts. The objective is to help structure application ontologies in areas where specific artefacts are present - in other words, virtually any area of activity. The conceptualization relies on recent philosophical and psychological research on artefacts, having resulted in a largely consensual theoretical basis. Furthermore, this ontology of artefacts extends the foundational DOLCE ontology and supplements its axiomatization. The conceptual primitives are as follows: artificial entity, intentional production (...) of entities, (state of) capacity, capacity to play a role in actions of a given type, function and functional object. These primitives enable artefacts in general to be characterized as intentionally and successfully produced entities, and isolate an important subclass of “technical” artefacts to which a function is ascribed. Lastly, we emphasize the novelty of this ontology by comparing it with other works with similar objectives. (shrink)

Pourquoi réunir des textes d'entretiens qui s'étendent presque sur vingt ans? Il arrive que des pourparlers durent si longtemps qu'on ne sait plus s'ils font encore partie de la guerre ou déjà de la paix. Il est vrai que la philosophie ne se sépare pas d'une colère contre l'époque, mais aussi d'une sérénité qu'elle nous assure. La philosophie cependant n'est pas une Puissance. Les religions, les Etats, le capitalisme, la science, le droit, l'opinion, la télévision sont des puissances, mais pas (...) la philosophie. La philosophie peut avoir de grandes batailles intérieures (idéalisme - réalisme etc.) mais ce sont des batailles pour rire. N'étant pas une puissance, la philosophie ne peut pas engager de bataille avec les puissances, elle mène en revanche une guerre sans bataille, une guérilla contre elles. Et elle ne peut pas parler avec elles, elle n'a rien à leur dire, rien à communiquer, et mène seulement des pourparlers. Comme les puissances ne se contentent pas d'être extérieures, mais aussi passent en chacun de nous, c'est chacun de nous qui se trouve sans cesse en pourparlers et en guérilla avec lui-même, grâce à la philosophie.

Until recently, cognitive science focused on such mental functions as problem solving, grammar, and pattern-the functions in which the human mind most closely resembles a computer. But humans are more than computers: we invent new meanings, imagine wildly, and even have ideas that have never existed before. Today the cutting edge of cognitive science addresses precisely these mysterious, creative aspects of the mind.The Way We Think is a landmark analysis of the imaginative nature of the mind. Conceptual blending is already (...) widely known in research laboratories throughout the world; this book, written to be accessible to both lay readers and interested scientists, is its definitive statement. Gilles Fauconnier and Mark Turner show that conceptual blending is the root of the cognitively modern human mind, and that conceptual blends themselves are continually combined and reblended to create the rich mental fabric in which we live.The Way We Think shows how this blending operates; how it is affected by (and gives rise to) language, identity, culture, and invention; and how we imagine what could be and what might have been. The result is a bold and exciting new view of how the mind works. (shrink)

At last available in paperback, this book anticipates and explains the post-structuralist turn to empiricism. Presenting a challenging reading of David Hume's philosophy, the work is invaluable for understanding the progress of Deleuze's thought.
