Abstract
To the origin of psychoanalysis, in the thought of his founder, Sigmund Freud, the unconscious is properly timeless. In this work we will analyze the concept of Real in Jacques Lacan's thought, and at the same time we will try to understand the functioning of après-coup temporality on the relationship between the time of trauma and the time of symptom. Doing this, we will try to answer an essential question: if the concept of
Real is the key concept of last Jacques Lacan's thought, which is his own temporality? Answering this question we will try to catch a pure and transcendental temporality of Real.
