Famous quotes containing the word license:

    It would much conduce to the public benefit, if, instead of discouraging free-thinking, there was erected in the midst of this free country a dianoetic academy, or seminary for free-thinkers, provided with retired chambers, and galleries, and shady walks and groves, where, after seven years spent in silence and meditation, a man might commence a genuine free-thinker, and from that time forward, have license to think what he pleased, and a badge to distinguish him from counterfeits.
    George Berkeley (1685–1753)
