In this article I analize the concept of Truth and the way it affects the subject and its perception of reality and the world. I demonstrate that, ultimately, as Lacan has established in Book 11, our unconscious is structured like a language, which means that behind the Real that inhabits us there is no essence, no ultimate meaning to help us understand, for instance, the difference between reality and fiction, good and bad, justice and injustice, democracy and dictatorship. There are no more clear boundaries and there is no Absolute, no certainty. Instead there is a split, a division, a doubleness. This twofoldness has resulted in a crisis that has affected the main institutions of Western civilization. That situation has been scrutinized by different literary texts and in particular by writers like mexican Enrique Serna, who deconstructs and criticizes the social and political environment that surrounds the main character in his novel La doble vida deJesús.
