Abstract

Sartre presented ‘Existentialism and Humanism’ to a popular audience in Paris late in 1945. As he implies in the discussion which is appended to the text of the lecture (pp. 57–58), he was here simplifying his views so as to make them intelligible to a wide audience. In this he succeeded only too well; the lecture has become exceedingly well known and has been regarded as a definitive presentation not only of Sartre's philosophy at the time, but also of ‘existentialism’. One thing I hope to show in this essay is that this is not a sensible view to take; Sartre's text requires a good deal of interpretation and qualification in the light of his other writings of the period, and what emerges is a position which is uniquely his own. One way in which this can be seen is by considering Heidegger's ‘Letter on Humanism’ of 1947 which is a response to Sartre's lecture and is, indeed, Heidegger's only direct response to Sartre's work. In the lecture Sartre had associated Heidegger with himself as an ‘existential atheist’ (p. 26), but in his letter Heidegger emphatically dissociates himself both from atheism and from existentialism as characterized by Sartre, and goes on to criticize the position advanced by Sartre in the lecture. Yet despite the popular exaggeration of the significance of Sartre's lecture, it is certainly worth studying; for not only is it short and accessible, though in some respects misleading, it is also one of Sartre's few indications of the positive ethical theory which so many of his writings require but do not supply.
