"In these seminar sessions, philosopher Jacques Derrida deconstructs perhaps the oldest dichotomy of all-life and death-giving him the opportunity to delve into a broad range of topics, from the work of French geneticist FrancÌʹois Jacob and epistemologist Georges Canguilhem to Freudian psychoanalysis and modern German philosophy, especially Nietzsche and Heidegger. Throughout, Derrida's attention is, as ever, on language, especially when it comes to discourses (such as scientific ones) that he understands to be suppressing the inherent instability of linguistic signs and the ambiguities behind even the most innocuous of terms. Appearing for the first time in English in a masterful translation by Pascale-Anne Brault and Michael Naas, these seminars from 1975-1976 represent a turning point in Derrida's thought, one that helps us better understand the influential work he would go on to produce in the decades to come"--
