It is difficult to place Deleuze’s philosophy within the hermeneutic paradigm that characterizes the philosophy of the second half of the XXth century, since he contrasted always the experimentation principle to the concepts of understanding and interpretation. Deleuze intended to forge his philosophy as experimental thought, as an alternative to the intents to establish everywhere ‘interpretation machines’. This paper thus seeks to sketch, the singularities of Deleuze’s experimentalism, from his practice as a historian of phi- losophy, to his project of (...) a philosophical constructivism. (shrink)
