By Martin Heidegger (writer), Carlos Másmela (translator)

In the winter semester of 1942-1943, Martin Heidegger gave a lecture at the University of Freiburg under the title "Parmenides and Heraclitus". In it the German philosopher dealt with the interpretation of the Parmenidean Poem, with a deep and fertile reflection on the name and the word alétheia, its translation, the conflict of its unconcealment-concealment, the look, the being.
