Famous quotes containing the word activity:

    The mob is man voluntarily descending to the nature of the beast. Its fit hour of activity is night. Its actions are insane like its whole constitution. It persecutes a principle; it would whip a right; it would tar and feather justice, by inflicting fire and outrage upon the houses and persons of those who have these. It resembles the prank of boys, who run with fire-engines to put out the ruddy aurora streaming to the stars.
    Ralph Waldo Emerson (1803–1882)

    A constant smirk upon the face, and a whiffling activity of the body, are strong indications of futility.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    Every writer is necessarily a critic—that is, each sentence is a skeleton accompanied by enormous activity of rejection; and each selection is governed by general principles concerning truth, force, beauty, and so on.... The critic that is in every fabulist is like the iceberg—nine-tenths of him is under water.
    Thornton Wilder (1897–1975)
