“Not speaking and speaking are both human ways of being in the world, and there are kinds and grades of each. There is the dumb silence of slumber or apathy; the sober silence that goes with a solemn animal face; the fertile silence of awareness, pasturing the soul, whence emerge new thoughts; the alive silence of alert perception, ready to say, “This… this…”; the musical silence that accompanies absorbed activity; the silence of listening to another speak, catching the drift and helping him be clear; the noisy silence of resentment and self-recrimination, loud and subvocal speech but sullen to say it; baffled silence; the silence of peaceful accord with other persons or communion with the cosmos.”
