In this analysis I intend to explicate in a critical manner the concept of "truth" as formulated within the philosophic framework of Gilles Deleuze. The main text I will focus on in coming to understand Deleuze's "truth" is his Proust and Signs. This work, while being devoted towards understanding Proust's A la Recherche du temps perdu, is not just an explication of Proust's own thought but is rather Deleuze's own thinking within the Proustian "world." Deleuze will argue that Proust's Search is a search for truth, which is derived entirely from the multiplicity of signs and their relationship to the different lines of time. In order to further understand what Deleuze's conception consists of, I will look to Alain Badiou's criticism of Deleuzian thought as presented in his Deleuze: The Clamor of Being. I hope to show that Badiou's characterization of Deleuze as a Neoplatonist is a misreading. In order to do this I will investigate into the greater Deleuzian canon, as well as contemporary commentators and critics, in order to show that the conception of truth is intimately related to the multiplicity of signs, and the "essence" of which they are a product of. I will show that contrary to what some commentators and critics argue, truth is not only important for Deleuze's ontology, but absolutely fundamental.
