If there is anything I have learned about men and women, it is that there is a deeper spirit of altruism than is ever evident. Just as the rivers we see are minor compared to the underground streams, so, too, the idealism that is visible is minor compared to what people carry in their hearts unreleased or scarcely released.
Albert SchweitzerThe last fact which knowledge can discover is that the world is a manifestation, and in every way a puzzling manifestation, of the universal will to live.
