A BODY THAT EXPERIENCES AND EVALUATES: ETHICS IN DELEUZE IN THE LIGHT OF THE "GREAT IDENTITY" SPINOZA-NIETZSCHE

Ethics is a constant theme in Gilles Deleuze's philosophy even though it does not seem to figure as the main subject in his books. This happens because, according to him, practical philosophy,formed both by ethics and politics - is coextensive to philosophy as a whole. On the one hand, there is no purely theoretical or speculative philosophy; on the other hand, ethics is not one amongst other philosophical disciplines, but its practical and always present dimension, there being no reason to be treated separately Thus, to approach ethics in Deleuze's thought means to go through all his writings to choose one key The aim of this paper is to explore how Deleuze launches what he calls a great Spinoza-Nietzsche identity as the key the basis,for his conception ofethics. Alormula is pmposedfor ethics in Deleuze philosophy: a body that experiments and evaluates. From this formula, a first axis to be worked is highlighted: Deleuzean ethics as a body ethics. The second axis hey on the important opposition between ethics and morals. A third axis is the relation between ethics and ontology. Finally a fourth and last axis is ethical formation understood as continuous apprenticeship.
