The death-drive runs as a red thread through a reading of Lacan. Starting from a clinic of suicide, Lacan proposes a theory whih is based on a split that is present at every level of the human structure: the real (biological), the imaginary (narcissistic), the symbolic (linguistic), up to and including the fantasma (primordial masochism). We attempt to draw a lesson from this concerning the cure and the problematic field of mental health.
