Composition is a process of combination, in which thought puts together complementary truths, and talent fuses into harmony the most contrary qualities of style. So that there is no composition without effort, without pain even, as in all bringing forth. The reward is the giving birth to something living--something, that is to say, which, by a kind of magic, makes a living unity out of such opposed attributes as orderliness and spontaneity, thought and imagination, solidity and charm.
