Can love be in aught allied to dissipation? Let us love by refusing, not accepting one another. Love and lust are far asunder. The one is good, the other bad.
(Henry David Thoreau (1817-1862), U.S. philosopher, author, naturalist. Essay on "Chastity and Sensuality" in letter, September 1852, to Harrison Blake, in The Writings of Henry David Thoreau, vol. 6, p. 206, Houghton Mifflin (1906).)
