The words seduction and ethics, which at first sight seem mutually exclusive, are at the heart of the analytic perspective. Vivian Chetrit-Vatine takes as her starting-point an encounter, which is not necessarily consensual, between Emmanuel Levinas's 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.
