 Deleuze is noteworthy for his rejection of the Heideggerian notion of the “end of metaphysics.” In an interview, he once offered this self-assessment: “I feel myself to be a pure metaphysician.... Bergson says that modern science hasn’t found its metaphysics, the metaphysics it would need. It is this metaphysics that interests me.” (Villani 1999: 130) We should also point to the extent of his non-philosophical references (inter alia, differential calculus, thermodynamics, geology, molecular biology, population genetics, ethology, embryology, anthropology, psychoanalysis, economics, linguistics, and even esoteric thought); his colleague Jean-François Lyotard spoke of him as a “library of Babel.” Deleuze’s influence reaches beyond philosophy; his work is approvingly cited by, and his concepts put to use by, researchers in architecture, urban studies, geography, film studies, musicology, anthropology, gender studies, literary studies and other fields.
