Famous quotes containing the word actions:

    “One will seldom go wrong in attributing extreme actions to vanity, moderate ones to habit, and petty ones to fear.”
    —Friedrich Nietzsche (1844–1900)

    “From a purely external point of view there is no will; and to find will in any phenomenon requires a certain empathy; we observe a man’s actions and place ourselves partly but not wholly in his position; or we act, and place ourselves partly in the position of an outsider.”
    —T.S. (Thomas Stearns)

    “I judge a man by his actions with men, much more than by his declarations Godwards—When I find him to be envious, carping, spiteful, hating the successes of others, and complaining that the world has never done enough for him, I am apt to doubt whether his humility before God will atone for his want of manliness.”
    —Anthony Trollope (1815–1882)
