We want to stand upon our own feet and look fair and square at the world-- its good facts, its bad facts, its beauties, and its ugliness;
see the world as it is and be not afraid of it. Conquer the world by intelligence and not merely by being slavishly subdued by the terror that comes from it.
-- Bertrand Russell
