Famous quotes containing the words dark and/or matter:

    Before the leaves can mount again
    To fill the trees with another shade,
    They must go down past things coming up.
    They must go down into the dark decayed.
    Robert Frost (1874–1963)

    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)
