On the one hand:The subject begins the analysis by talking about himself without talking to you or talking to you without talking about himself. When he can talk to you about himself the analysis is over. (Lacan: Introduction to Jean Hyppolite’s commentary on Freud’s Verneinung. Cf Écrits, 1966, p373)
