Martin Heidegger
What is Being? We have forgotten the question.
Being and Time essential
His main book, written and published by him. An unfinished treatise: the announced second part never appeared. Our corpus has extracts (§ 1-4, 9, 27, 40, 46-53) in German, with Martineau's French (1985) and Macquarrie and Robinson's English (1962), both from unproofread scans.
What Is Metaphysics? essential
Inaugural lecture at the University of Freiburg (24 July 1929), written and published by him: this is where we read "the nothing nothings". We have the first 1929 printing in German (poor scan), without the 1943 postface or the 1949 introduction, with Miles Groth's very literal English.
The Self-Assertion of the German University (rectoral address)
Delivered on 27 May 1933 at Freiburg, when he was rector and a member of the Nazi party. Not in our corpus. See the box on the Nazi commitment.
Letter on Humanism essential
Written in autumn 1946 in answer to Jean Beaufret, published in 1947, written and published by him. He also answers Sartre in it. We do not have the German text: we quote Capuzzi's English (1998) and Munier's French (1957, reprinted 1966).
The Question Concerning Technology essential
Lecture given in Munich (1953), published in 1954, written and published by him. We only have William Lovitt's English (1977), not the German.
Black Notebooks (Schwarze Hefte)
Personal notes from 1931 to the 1970s, published from 2014 (Gesamtausgabe, vol. 94 and following), after his death. They contain antisemitic passages. Not in our corpus. See the box.
