Jean Beaufret is perhaps best known for posing the questions to which Martin Heidegger responded in his famous “Letter on Humanism.” These questions, hastily written in a Paris café, constitute an early and improvised moment that was to form a profound philosophical engagement and friendship between the two thinkers. Mark Sinclair presents, for the first time in English translation, the first of four volumes of correspondence between Heidegger and Beaufret. This volume covers Heidegger’s attachments to Greek thinking in six letters—“The Birth of Philosophy,” “Heraclitus and Parmenides,” “Reading Parmenides,” “Zeno,” “A Note on Plato and Aristotle,” and “Energeia and Actus.” This frank exchange shows Heidegger in a more personal and tentative light and brings out his deep attachments to French intellectual traditions.
