Famous quotes containing the words natural, science and/or technology:

    “Art is not tame, and Nature is not wild, in the ordinary sense. A perfect work of man’s art would also be wild or natural in a good sense.”
    —Henry David Thoreau (1817–1862)

    “The great pagan world of which Egypt and Greece were the last living terms ... once had a vast and perhaps perfect science of its own, a science in terms of life. In our era this science crumbled into magic and charlatanry. But even wisdom crumbles.”
    —D.H. (David Herbert)

    “The successor to politics will be propaganda. Propaganda, not in the sense of a message or ideology, but as the impact of the whole technology of the times.”
    —Marshall McLuhan (1911–1980)
