Famous quotes containing the word levers:

    There are two levers for moving men—interest and fear.
    Napoleon Bonaparte (1769–1821)

    The sense of doing good , the satisfaction of being right, the joy of looking favorably upon oneself, dear sir, are powerful levers for keeping us upright and making us progress. On the other hand, if men are deprived of that feeling, they are changed into rabid dogs.
    Albert Camus (1913–1960)

    Certain anthropologists hold that man, having discovered tools, ceased to evolve biologically. Animals, never having discovered them, continue to fashion drills out of their beaks, oars out of their hind feet, wings out of their forefeet, suits of armor out of their hides, levers out of their horns, saws out of their teeth. Whether this be true or not, all authorities agree that man is the tool-using animal. It sets him off from the rest of the animal kingdom as drastically as does speech.
    Stuart Chase (1888–1985)
