Famous quotes containing the word write:
“It is dangerous to leave written that which is badly written. A chance word, upon paper, may destroy the world. Watch carefully and erase, while the power is still yours, I say to myself, for all that is put down, once it escapes, may rot its way into a thousand minds, the corn become a black smut, and all libraries, of necessity, be burned to the ground as a consequence. Only one answer: write carelessly so that nothing that is not green will survive.”
—William Carlos Williams (1883–1963)
