Famous quotes containing the word necessity:

    The use of force alone is but temporary. It may subdue for a moment; but it does not remove the necessity of subduing again: and a nation is not governed, which is perpetually to be conquered.
    Edmund Burke (1729–1797)

    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)
