Abstract

I show how Hans Jonas, one of Heidegger's most distinguished Jewish students, traces his mentor's susceptibility to Nazism to a moral nihilism at the heart of Heidegger's teaching in "Being and Time". I then demonstrate how Jonas's own "existential interpretation of the biological facts" and metaphysical grounding of "an imperative of responsibility" provide one of the most systematic and challenging rejoinders to the moral failings of Heidegger's thought
