Jacques Lacan's 1959–60 seminar The Ethics of Psychoanalysis is rich in ideas and deserves a very careful commentary, the kind that Bill Richardson has undertaken so successfully over the years. Even so, what I propose to do here is much more modest; I would like to highlight some of the key elements of Lacan's discussion in the last section of the seminar and suggest a possibly illuminating parallel between Lacan and Heidegger.
