Gilles Deleuze (January 18, 1925–November 4, 1995) was one of the most influential and prolific French philosophers of the second half of the twentieth century. Deleuze conceived of philosophy as the production of concepts, and he characterized himself as a “pure metaphysician.” In his magnum opus Difference and Repetition , he tries to develop a metaphysics adequate to contemporary mathematics and science—a metaphysics in which the concept of multiplicity replaces that of substance, event replaces essence and virtuality replaces possibility. Deleuze (...) was also well-known for a number of important monographs he published in the history of philosophy (on Hume, Nietzsche, Kant, Bergson, Spinoza, Foucault, and Leibniz), as well as for his writings on the various arts, which include a two- volume study of the cinema, books on Proust and Sacher-Masoch, a monograph on the painter Francis Bacon, and a collection of essays on literature. Deleuze considered these latter works as pure philosophy, and not criticism, since he sought to create the concepts that correspond to the artistic practices of painters, filmmakers, and writers. In 1968, he met Félix Guattari, a political activist and radical psychoanalyst, with whom he wrote several works, among them the two-volume Capitalism and Schizophrenia , comprised of Anti-Oedipus (1972) and A Thousand Plateaus (1980). Their final collaboration was What is Philosophy? (1991). (shrink)

The aim of this article is to clarify the meaning of a naturalistic position within philosophy of biology, against the background of an alternative view, founded on the basic insights of transcendental philosophy. It is argued that the apparently minimal and neutral constraints naturalism imposes on philosophy of science turn out to involve a quite heavily constraining metaphysics, due to the naturalism’s fundamental neglect of its own perspective. Because of its intrinsic sensitivity to perspectivity and historicity, transcendental philosophy can avoid (...) this type of hidden metaphysics. (shrink)

In What Is Philosophy?, Gilles Deleuze and Félix Guattari distinguish the functions of philosophy, art and science. According to this distinction, the primary purpose of philosophy is to invent concepts, the purpose of art to bring forth percepts, or sensorial aggregates, and that of science to delineate functions. This article aims to show that these distinctions are not as clear-cut as they appear. Using Deleuze and Guattari’s proposition that ‘philosophy is the art of forming, inventing, and fabricating concepts’ as a (...) reference point, it suggests that the corresponding philosophical practice is intimately connected to art and science. Studying the conceptual drawings in Deleuze’s texts, the article situates his philosophy in the French tradition of epistemology (Cavaillès, Bachelard and Canguilhem). As a result, the conceptual work of this philosophy can be seen as intensively responding to the creative problems posed by the dynamics of science in contemporary societies. (shrink)
