HERACLITUS

Martin Heidegger

Th e following is the fi rst complete English translation of Volume 55 of Martin Heidegger’s Gesamtausgabe , published by Vittorio Klostermann in 1979 (three years aft er Heidegger’s death) and revised in 1987. Edited by Manfred Frings, GA 55 contains two lecture- courses off ered by Heidegger at the University of Freiburg: the fi rst, Th e Inception of Occidental Th inking (given in the Summer semester of 1943); the second, Heraclitus’s Doctrine of the Logos (given in the Summer semester of 1944). Taken together, these two lecture- courses off er Heidegger’s most sustained and focused engagement with the early-Greek thinker Heraclitus, whom Heidegger considered to be one of only three thinkers (the others being Anaximander and Parmenides) who thought within the region of the inception of Occidental thinking, and who thought something of that inception itself.
