Famous quotes containing the word substituted:

    Methinks the human method of expression by sound of tongue is very elementary, & ought to be substituted for some ingenious invention which should be able to give vent to at least six coherent sentences at once.
    Virginia Woolf (1882–1941)

    Verily, the Indian has but a feeble hold on his bow now; but the curiosity of the white man is insatiable, and from the first he has been eager to witness this forest accomplishment. That elastic piece of wood with its feathered dart, so sure to be unstrung by contact with civilization, will serve for the type, the coat-of-arms of the savage. Alas for the Hunter Race! the white man has driven off their game, and substituted a cent in its place.
    Henry David Thoreau (1817–1862)

    A point of view can be a dangerous luxury when substituted for insight and understanding.
    Marshall McLuhan (1911–1980)
