Famous quotes containing the words dark and/or matter:
“Light silence, dark speech.”
—Samuel Beckett (1906–1989)
“See, in the Navy, during the war, I got used to the idea that something might happen to me, I might not make it. Well, I also got used to the idea that my wife and children were safe at home, they’d be all right no matter what. But what I didn’t reckon with was that in this, this kind of a monstrous war, something might happen to them, and not to me. Well it did, and I can’t, I can’t cope with it.”
—John Paxton (1911–1985)
