The openness of Dasein.

In a letter to Jean Beaufret on November 23, 1945, Heidegger writes: “‘Dasein’ is a keyword of my thought and therefore also the occasion for gross misinterpretations. ‘Da-sein’ for me means not so much ‘Here I am!’ but—if I can put it in a perhaps impossible French—‘being-the-there.’ And ‘the there’ is equal to ἀλήθεια: unconcealment – openness.” The letter is printed with a French translation in Martin Heidegger, Lettre sur l’humanisme, ed. and trans. Roger Munier (Paris: Aubier, 1964), 180–85, here 182–83.
