Famous quotes containing the word necessity:
“No picture of life can have any veracity that does not admit the odious facts. A man’s power is hooped in by a necessity which, by many experiments, he touches on every side until he learns its arc.”
—Ralph Waldo Emerson (1803–1882)
“The secret of the illusoriness is in the necessity of a succession of moods or objects. Gladly we would anchor, but the anchorage is quicksand.”
—Ralph Waldo Emerson (1803–1882)
“Whoever is not in the possession of leisure can hardly be said to possess independence. They talk of the dignity of work. Bosh. True work is the necessity of poor humanity’s earthly condition. The dignity is in leisure. Besides, 99 hundredths of all the work done in the world is either foolish and unnecessary, or harmful and wicked.”
—Herman Melville (1819–1891)
