This article analyzes the links between the conception of the body and of sexuality found in Freud and Merleau-Ponty. The French philosopher refers to Freud in various of his works, and performs a reading of Freud through which he rescues the meaning that the latter gives to sexuality as he integrates it into the totality of the person, without making it into a blind or merely instinctive force. As a consequence of this integration, the notions of the unconscious and of instinct or drive are interpreted in the light of the meaning or signification that they have in the person's behavior. Merleau-Ponty's notion of pre-reflective knowledge plays a decisive role in this understanding of meaning.
