Abstract: This contribution discusses the dissociation in the work of Heidegger of terms as central as “silence”, “truth”, and “essence”, through the game of silence with the “non-essence of truth (das Unwesen der Wahrheit)”, the “change of the essence of truth (Wesenswandel der Wahrheit)” and the “non-essence in the essence of truth (das Unwesenim Wesen der Wahrheit)”.
