Famous quotes containing the word action:

    ...a fixed aim furnishes us with a fixed measure, by which we can decide whether such or such an action proposed is worth trying for or not, and as aims must vary with the individual, the decisions of any two people as to the desirableness of an action may not be the same.
    Anna C. Brackett (1836–1911)

    His eloquence was of every kind, and he excelled in the argumentative as well as in the declamatory way. But his invectives were terrible, and uttered with such energy of diction, and stern dignity of action and countenance, that he intimidated those who were the most willing and the best able to encounter him. Their arms fell out of their hands, and they shrunk under the ascendant which his genius gained over theirs.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    The beginning, middle, and end of the birth, growth, and perfection of whatever we behold is from contraries, by contraries, and to contraries; and whatever contrarity is, there is action and reaction, there is motion, diversity, multitude, and order, there are degrees, succession and vicissitude.
    Giordano Bruno (1548–1600)
