Famous quotes containing the word standards:

    “With his brows knit, his mind made up, his will resolved and resistless, he advances, crashing his way through the host of weak, half-formed, dilettante opinions, honest and dishonest ways of thinking, with their standards raised, sentimentalities and conjectures, and tramples them all into dust. See how he prevails; you don’t even hear the groans of the wounded and dying.”
    —Henry David Thoreau (1817–1862)

    “As long as our people quote English standards they dwarf their own proportions.”
    —Ralph Waldo Emerson (1803–1882)

    “To arrive at a just estimate of a renowned man’s character one must judge it by the standards of his time, not ours.”
    —Mark Twain [Samuel Langhorne Clemens] (1835–1910)
