Famous quotes containing the word write:
“To write is to make oneself the echo of what cannot cease speakingand since it cannot, in order to become its echo I have, in a way, to silence it. I bring to this incessant speech the decisiveness, the authority of my own silence.”
—Maurice Blanchot (b. 1907)
