Famous quotes containing the word universal:
“We have had many harbingers and forerunners; but of a purely spiritual life, history has afforded no example. I mean we have yet no man who has leaned entirely on his character, and eaten angels’ food; who, trusting to his sentiments, found life made of miracles; who, working for universal aims, found himself fed, he knew not how; clothed, sheltered, and weaponed, he knew not how, and yet it was done by his own hands.”
—Ralph Waldo Emerson (1803–1882)
