"Afraid!" cried Gale, as if with indignation; "afraid you are a materialist! You haven't got much notion of what there really is to be afraid of! Materialists are all right; they are at least near enough to heaven to accept the earth and not imagine they made it. The dreadful doubts are not the doubts of the materialist. The dreadful doubts, the deadly and damnable doubts, are the doubts of the idealist."

"I always imagined you were an idealist," said Garth.

"I use the word idealist in its philosophical sense. I mean the real sceptic who doubts matter and the minds of others and everything except his own ego. I have been through it myself; as I have been through nearly every form of infernal idiocy. That is the only use I am in the world; having been every kind of idiot. But believe me, the worst and most miserable sort of idiot is he who seems to create and contain all things. Man is a creature; all his happiness consists in being a creature; or, as the Great Voice commanded us, in becoming a child. All his fun is in having a gift or present; which the child, with profound understanding, values because it is 'a surprise'. But surprise implies that a thing comes from outside ourselves; and gratitude that it comes from someone other than ourselves. It is thrust through the letter-box; it is thrown in at the window; it is thrown over the wall. Those limits are the lines of the very plan of human pleasure.

"I also dreamed that I had dreamed of the whole creation. I had given myself the stars for a gift; I had handed myself the sun and moon. I had been behind and at the beginning of all things; and without me nothing was made that was made. Anybody who has been in that centre of the cosmos knows that it is to be in hell. And there is only one cure for it. Oh, I know that people have written all kinds of cant and false comfort about the cause of evil; and of why there is pain in the world. God forbid that we should add ourselves to such a chattering monkey-house of moralists. But for all that, this truth is true; objectively and experimentally true. There is no cure for that nightmare of omnipotence except pain; because that is the thing a man knows he would not tolerate if he could really control it. A man must be in some place from which he would certainly escape if he could, if he is really to realize that all things do not come from within. That is the meaning of that mad parable or mystery play you have seen acted here like an allegory. I doubt whether any of our action is really anything but an allegory. I doubt whether any truth can be told except in a parable."
