This 1986 conversation with Jacques Derrida about Heidegger offers Derrida at his most disarmed and tentative, venturing into areas of Heidegger's thought that he was 'the least sure about' around the mid 1980s. Topics discussed include the status of the question, technology, animality, the problem of life, epochality, the ontological difference, as well as a brief but poignant discussion on how to avoid future Holocausts.
