Letter on Humanism

The influence of Heidegger on Sartre's Being and Nothingness is marked, but Heidegger felt that Sartre had misread his work, as he argued in later texts such as the "Letter on 'Humanism'." "Letter on 'Humanism'" is often seen as a direct response to Sartre's 1945 lecture "Existentialism is a Humanism."
