We know how it sounds when the voice of those who are absent animate their words as we read them, as if from the inside of the text. How long after a disappearance is a voice activated through a postcard, a note on a piece of paper or a book? I reach for Bernard Stiegler’s books soon after receiving the news of his death in early August. There are many in my shelf, but far from all of the more than thirty that he wrote since the first volume of “La technique et le temps” in 1994. I read and I hear.
