One of the important questions in the discourse of Valery, French author of 20th century, is the question of another who achieves the knowledge. Another is treated in a new way. Indeed, another is defined in touch with Me of the author, that’s the reflection of Me, and a dialectic is established between the two: Me and another. In his discourse, who receives the meaning is in front of two instances of who enunciates: ipseity and samely, one-idem and one-ipse. Indeed, Paul Valery defines another in oneself who speaks. He tries to show the relationship between Me and another. We benefit from semiotics of Paris school, the work of Jacques Fontanille and also the analysis of Paul Ricoeur, specially his work: oneself as another. The objective of this research is to show how another defines itself compared with me and how the author achieves the knowledge and recognizes himself.
