"THE PESSIMIST is commonly spoken of as the man in revolt. He is not. Firstly, because it requires some cheerfulness to continue in revolt, and secondly, because pessimism appeals to the weaker side of everybody, and the pessimist, therefore, drives as roaring a trade as the publican. The person who is really in revolt is the optimist, who generally lives and dies in a desperate and suicidal effort to persuade all the other people how good they are. It has been proved a hundred times over that if you really wish to enrage people and make them angry, even unto death, the right way to do it is to tell them that they are all the sons of God. Jesus Christ was crucified, it may be remembered, not because of anything he said about God, but on a charge of saying that a man could in three days pull down and rebuild the Temple. Every one of the great revolutionists, from Isaiah to Shelley, have been optimists. They have been indignant, not about the badness of existence, but about the slowness of men in realizing its goodness. The prophet who is stoned is not a brawler or a marplot. He is simply a rejected lover. He suffers from an unrequited attachment to things in general."
