For sites on the subject of George Santayana (1863-1952), whose naturalism and emphasis on constructive imagination announced important intellectual changes on both sides of the Atlantic.
"To have imagination and taste, to love the best, to be carried by the contemplation of nature to a vivid faith in the ideal, all this is more, a great deal more, than any science can hope to be. The poets and philosophers who express this aesthetic experience and stimulate the same function in us by their example, do a greater service to mankind and deserve higher honor than the discoveries of historical truths."
