Famous quotes containing the word necessity:

    “Old-fashioned determinism was what we may call hard determinism. It did not shrink from such words as fatality, bondage of the will, necessitation, and the like. Nowadays, we have a soft determinism which abhors harsh words, and, repudiating fatality, necessity, and even predetermination, says that its real name is freedom; for freedom is only necessity understood, and bondage to the highest is identical with true freedom.”
    —William James (1842–1910)

    “All real freedom springs from necessity, for it can be gained only through the exercise of the individual will, and that will can be roused to energetic action only by the force of necessity acting upon it from the outside to spur it to effort.”
    —Anna C. Brackett (1836–1911)

    “Perhaps love is a compelling necessity imposed on man by God that has something to do with suffering”
    —Zora Neale Hurston (1891–1960)
