Famous quotes containing the word defects:

    The machine is impersonal, it takes the pride away from a piece of work, the individual merits and defects that go along with all work that is not done by a machine—which is to say, its little bit of humanity.
    Friedrich Nietzsche (1844–1900)

    We often make use of envenomed praise, that reveals on the rebound, as it were, defects in those praised which we dare not expose any other way.
    François, Duc De La Rochefoucauld (1613–1680)

    All conservatives are such from personal defects. They have been effeminated by position or nature, born halt and blind, through luxury of their parents, and can only, like invalids, act on the defensive. But strong natures, backwoodsmen, New Hampshire giants, Napoleons, Burkes, Broughams, Websters, Kossuths, are inevitable patriots, until their life ebbs, and their defects and gout, palsy and money, warp them.
    Ralph Waldo Emerson (1803–1882)
