Famous quotes containing the word license:

    Surely the fates are forever kind, though Nature’s laws are more immutable than any despot’s, yet to man’s daily life they rarely seem rigid, but permit him to relax with license in summer weather. He is not harshly reminded of the things he may not do.
    Henry David Thoreau (1817–1862)
