But there are some people, nevertheless—and I am one of them—who think that the most practical and important thing about a man is still his view of the universe. We think that for a landlady considering a lodger, it is important to know his income, but still more important to know his philosophy. We think that for a general about to fight an enemy, it is important to know the enemy’s numbers, but still more important to know the enemy’s philosophy. We think the question is not whether the theory of the cosmos affects matters, but whether in the long run, anything else affects them. In the fifteenth century men cross-examined and tormented a man because he preached some immoral attitude; in the nineteenth century we feted and flattered Oscar Wilde because he preached such an attitude, and then broke his heart in penal servitude because he carried it out. It may be a question which of the two methods was the more cruel; there can be no kind of question which was the more ludicrous. The age of the Inquisition has not at least the disgrace of having produced a society which made an idol of the very same man for preaching the very same things which it made him a convict for practising. Now, in our time, philosophy or religion, our theory, that is, about ultimate things, has been driven out, more or less simultaneously, from two fields which it used to occupy. General ideals used to dominate literature. They have been driven out by the cry of “art for art’s sake.” General ideals used to dominate politics. They have been driven out by the cry of “efficiency,” which may roughly be translated as “politics for politics’ sake.” Persistently for the last twenty years the ideals of order or liberty have dwindled in our books; the ambitions of wit and eloquence have dwindled in our parliaments. Literature has purposely become less political; politics have purposely become less literary. General theories of the relation of things have thus been extruded from both; and we are in a position to ask, “What have we gained or lost by this extrusion? Is literature better, is politics better, for having discarded the moralist and the philosopher?”
