We say, not lightly but very literally, that the truth has made us free. They say that it makes us so free that it cannot be the truth. To them it is like believing in fairyland to believe in such freedom as we enjoy. It is like believing in men with wings to entertain the fancy of men with wills. It is like accepting a fable about a squirrel in conversation with a mountain to believe in a man who is free to ask or a God who is free to answer. This is a manly and a rational negation, for which I for one shall always show respect. But I decline to show any respect for those who first of all clip the bird and cage the squirrel, rivet the chains and refuse the freedom, close all the doors of the cosmic prison on us with a clang of eternal iron, tell us that our emancipation is a dream and our dungeon a necessity; and then calmly turn round and tell us they have a freer thought and a more liberal theology.
The timidity of the child or the savage is entirely reasonable; they are alarmed at this world, because this world is a very alarming place. They dislike being alone because it is verily and indeed an awful idea to be alone. Barbarians fear the unknown for the same reason that Agnostics worship it - because it is a fact.
Poets do not go mad; but chess-players do. Mathematicians go mad, and cashiers; but creative artists very seldom. I am not, as will be seen, in any sense attacking logic: I only say that this danger does lie in logic, not in imagination.
