There is a great deal of difference between the optimism which says that things are perfect and the optimism which merely says (with a more primeval modesty) that they are very good. One optimism says that a one-legged man has two legs because it would be so dreadful if he had not. The other optimism says that the fact that the one-legged was born of a woman, has a soul, has been in love, and has stood alive under the stars, is a fact so enormous and thrilling that, in comparison, it does not matter whether he has one leg or five. One optimism says that this is the best of all possible worlds. The other says that it is certainly not the best of all possible worlds, but it is the best of all possible things that a world should be possible.

-G.F. Watts (1904)
