What we get from all this: Wittgenstein and the Philosophy of Life

Coming back from a reflection on a contemporary work of art and its convincing speculative suggestion, this paper is devoted to test the ambition to make sense of the statement that << life is desire >> - an instance of Lebensphilosophie, so to say - from the standpoint of the Wittgensteinian critique of philosophical discourse both according to the Tractatus and to the Philosophical Investigations. Coming forward this way we finally get, of course, to the conclusion that Vitalism would be basically unsinnig. But there would be some different passages of Wittgenstein's work which could include a reference to a kind of aesthetic `truth', so that we will end by trying an appeal to the Nietzschean criterion of truth in order to be able understand the subject in a deeper sense.
