The civility of no race can be perfect whilst another race is degraded.
(Ralph Waldo Emerson (1803-1882), U.S. essayist, poet, philosopher. "Address Delivered in Concord on the Anniversary of the Emancipation of the Negroes in the British West Indies, August 1, 1844," Miscellanies (1883, repr. 1903).)
Perfect friendship is the friendship of men who are good, and alike in excellence; for these wish well alike to each other qua good, and they are good in themselves.
(Aristotle (384-323 B.C.), Greek philosopher. Nicomachean Ethics 8.3; 1156b6-10, trans. by Ross-Urmson, The Complete Works of Aristotle, ed. Jonathan Barnes, Princeton, Princeton University Press (1985).)
