The philosopher’s task was well compared by Neurath to that of a mariner who must rebuild his ship on the open sea.”
—Willard Van Orman Quine (b. 1908)
“Mankind have such a deep stake in inward illumination, that there is much to be said by the hermit or monk in defence of his life of thought and prayer.”
—Ralph Waldo Emerson (1803–1882)
