Famous quotes containing the words dark and/or matter:
“These are the arks, the trophies, I erect,
That fortify thy name against old age;
And these thy sacred virtues must protect
Against the dark and Time’s consuming rage.”
—Samuel Daniel (1562–1619)
“We only seem to learn from Life that Life doesn’t matter so much as it seemed to do—it’s not so burningly important, after all, what happens. We crawl, like blinking sea-creatures, out of the Ocean onto a spur of rock, we creep over the promontory bewildered and dazzled and hurting ourselves, then we drop in the ocean on the other side: and the little transit doesn’t matter so much.”
—D.H. (David Herbert)
