Famous quotes containing the words activity and/or human:

    In literary circles, the men of trust and consideration, bookmakers, editors, university deans and professors, bishops, too, were by no means men of the largest literary talent, but usually of a low and ordinary intellectuality, with a sort of mercantile activity and working talent. Indifferent hacks and mediocrities tower, by pushing their forces to a lucrative point, or by working power, over multitudes of superior men, in Old as in New England.
    Ralph Waldo Emerson (1803–1882)

    Women—one half the human race at least—care fifty times more for a marriage than a ministry.
    Walter Bagehot (1826–1877)
