One of Jacques Derrida's most provocative works, Life Death deconstructs a deeply rooted dichotomy of Western thought: life and death. In rethinking the relationship between life and death, Derrida undertakes a multi-disciplinary analysis of a range of topics across philosophy, linguistics, and the life sciences. Derrida gave this seminar over fourteen sessions between 1975 and 1976 at the École normale supérieure in Paris to prepare students for the agrégation, a notoriously competitive exam. The theme for the exam that year was "Life and Death," but Derrida made a critical modification to the title by dropping the coordinating conjunction. The resulting title of Life Death poses a philosophical question about the close relationship between life and death. Through close readings of Freudian psychoanalysis, the philosophy of Nietzsche and Heidegger, French geneticist François Jacob, and epistemologist Georges Canguilhem, Derrida argues that death must be considered neither as the opposite of life nor as the truth or fulfillment of it, but rather as that which both limits life and makes it possible. Derrida thus not only questions traditional understandings of the relationship between life and death but also ultimately develops a new way of thinking about what he calls "life death."
