Famous quotes containing the words evidence, comparative and/or anatomy:

    Faith. Belief without evidence in what is told by one who speaks without knowledge, of things without parallel.
    Ambrose Bierce (1842–1914)

    That hour in the life of a man when first the help of humanity fails him, and he learns that in his obscurity and indigence humanity holds him a dog and no man: that hour is a hard one, but not the hardest. There is still another hour which follows, when he learns that in his infinite comparative minuteness and abjectness, the gods do likewise despise him, and own him not of their clan.
    Herman Melville (1819–1891)

    Man is a shrewd inventor, and is ever taking the hint of a new machine from his own structure, adapting some secret of his own anatomy in iron, wood, and leather, to some required function in the work of the world.
    Ralph Waldo Emerson (1803–1882)
