Abstract
The aim of this paper is to review the game concept of the French philosopher Gilles Deleuze (1925-1995) in his books Logic of Sense (1969) and The fold (1988). As suggested by other authors of contemporary metaphysics, Deleuze's issue with game arises from the evaluation of the philosophical and historical importance that reason represents for Leibniz. In this sense, this article gets the notion of play of principles in which Deleuze attempted, in 1988, to characterize the concept of principle in the German author. Because of the connections with the problem of ideal game, we focussed on establishing links with the principles with which Deleuze describes the game in Logic of Sense.
