According to Jacques Andre, "the patient's encounter with the analyst is a scene of seduction, the seductive statement being that of the fundamental rule or the invitation to address that which is most intimate or personal to a complete stranger." But the practice of psychoanalysis can only unfold if there is a strict respect for ethics. The words seduction and ethics, which at first sight seem mutually exclusive, are thus, as the author shows, at the heart of the analytic perspective. The author takes as her starting-point an encounter, which is not necessarily consensual, between Emmanuel Levinas' thought and his conception of philosophy as ethics - ethics understood as responsibility for the other - and that of the psychoanalyst Jean Laplanche, who posits the first adult other as a seducer of the young psyche from the outset, due to the transmission of enigmatic messages compromised by his or her unconscious. The analyst's ethical position is re-examined and with it the feminine/maternal origins of the human capacity for responsibility for the other.
