The present work that seeks to elaborate the subject's idea in Lacan. Initially, determined by the "social aspect", later by the "imaginary dimension", and last, for the "dimension of the language", thus subverted to the significant. After this digression, it is clarifield, as much as possible, Lacan's subject idea, through the analysis of the notion of the subject subversion. The analysis of that notion consists, basically, in a comment of the text "Subversion du Sujet et Dialectique du Désir dans I'lnconscient Freudien".
