1 The letter in its published form dates from 1947. Since 1945, Heidegger had been living in enforced retirement, and Beaufret's query gave him the opportunity (probably a welcome one) to expose in fuller scope the mise au point suggested in WM: Ep, bringing into clearer focus the relation between Heidegger I and Heidegger II. It is especially valuable, therefore, for the author's self-interpretation, although this aspect of the letter is less important for us who, thanks to subsequent publication of several works from the 1929–1947 period, are more familiar with the course of his development than his readers could be at that time." /> Letter on humanism - Richardson William | sdvig press
