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. (shrink)
