For we must remember that the materialist philosophy (whether true or not) is certainly much more limiting than any religion. In one sense, of course, all intelligent ideas are narrow. They cannot be broader than themselves. A Christian is only restricted in the same sense that an atheist is restricted. He cannot think Christianity false and continue to be a Christian; and the atheist cannot think atheism false and continue to be an atheist. But as it happens, there is a very special sense in which materialism has more restrictions than spiritualism. Mr. McCabe thinks me a slave because I am not allowed to believe in determinism. I think Mr. McCabe a slave because he is not allowed to believe in fairies. But if we examine the two vetoes we shall see that his is really much more of a pure veto than mine. The Christian is quite free to believe that there is a considerable amount of settled order and inevitable development in the universe. But the materialist is not allowed to admit into his spotless machine the slightest speck of spiritualism or miracle. Poor Mr. McCabe is not allowed to retain even the tiniest imp, though it might be hiding in a pimpernel. The Christian admits that the universe is manifold and even miscellaneous, just as a sane man knows that he is complex. The sane man knows that he has a touch of the beast, a touch of the devil, a touch of the saint, a touch of the citizen. Nay, the really sane man knows that he has a touch of the madman. But the materialist's world is quite simple and solid, just as the madman is quite sure he is sane. The materialist is sure that history has been simply and solely a chain of causation, just as the interesting person before mentioned is quite sure that he is simply and solely a chicken. Materialists and madmen never have doubts.
Spiritual doctrines do not actually limit the mind as do materialistic denials. Even if I believe in immortality I need not think about it. But if I disbelieve in immortality I must not think about it. In the first case the road is open and I can go as far as I like; in the second the road is shut. But the case is even stronger, and the parallel with madness is yet more strange. For it was our case against the exhaustive and logical theory of the lunatic that, right or wrong, it gradually destroyed his humanity. Now it is the charge against the main deductions of the materialist that, right or wrong, they gradually destroy his humanity; I do not mean only kindness, I mean hope, courage, poetry, initiative, all that is human. For instance, when materialism leads men to complete fatalism (as it generally does), it is quite idle to pretend that it is in any sense a liberating force. It is absurd to say that you are especially advancing freedom when you only use free thought to destroy free will. The determinists come to bind, not to loose. They may well call their law the "chain" of causation. It is the worst chain that ever fettered a human being. You may use the language of liberty, if you like, about materialistic teaching, but it is obvious that this is just as inapplicable to it as a whole as the same language when applied to a man locked up in a mad-house. You may say, if you like, that the man is free to think himself a poached egg. But it is surely a more massive and important fact that if he is a poached egg he is not free to eat, drink, sleep, walk, or smoke a cigarette. Similarly you may say, if you like, that the bold determinist speculator is free to disbelieve in the reality of the will. But it is a much more massive and important fact that he is not free to praise, to curse, to thank, to justify, to urge, to punish, to resist temptations, to incite mobs, to make New Year resolutions, to pardon sinners, to rebuke tyrants, or even to say "thank you" for the mustard.
In passing from this subject I may note that there is a queer fallacy to the effect that materialistic fatalism is in some way favourable to mercy, to the abolition of cruel punishments or punishments of any kind. This is startlingly the reverse of the truth. It is quite tenable that the doctrine of necessity makes no difference at all; that it leaves the flogger flogging and the kind friend exhorting as before. But obviously if it stops either of them it stops the kind exhortation. That the sins are inevitable does not prevent punishment; if it prevents anything it prevents persuasion. Determinism is quite as likely to lead to cruelty as it is certain to lead to cowardice. Determinism is not inconsistent with the cruel treatment of criminals. What it is (perhaps) inconsistent with is the generous treatment of criminals; with any appeal to their better feelings or encouragement in their moral struggle. The determinist does not believe in appealing to the will, but he does believe in changing the environment. He must not say to the sinner, "Go and sin no more," because the sinner cannot help it. But he can put him in boiling oil; for boiling oil is an environment. Considered as a figure, therefore, the materialist has the fantastic outline of the figure of the madman. Both take up a position at once unanswerable and intolerable.
Of course it is not only of the materialist that all this is true. The same would apply to the other extreme of speculative logic. There is a sceptic far more terrible than he who believes that everything began in matter. It is possible to meet the sceptic who believes that everything began in himself. He doubts not the existence of angels or devils, but the existence of men and cows. For him his own friends are a mythology made up by himself. He created his own father and his own mother. This horrible fancy has in it something decidedly attractive to the somewhat mystical egoism of our day. That publisher who thought that men would get on if they believed in themselves, those seekers after the Superman who are always looking for him in the looking-glass, those writers who talk about impressing their personalities instead of creating life for the world, all these people have really only an inch between them and this awful emptiness. Then when this kindly world all round the man has been blackened out like a lie; when friends fade into ghosts, and the foundations of the world fail; then when the man, believing in nothing and in no man, is alone in his own nightmare, then the great individualistic motto shall be written over him in avenging irony. The stars will be only dots in the blackness of his own brain; his mother's face will be only a sketch from his own insane pencil on the walls of his cell. But over his cell shall be written, with dreadful truth, "He believes in himself."
All that concerns us here, however, is to note that this panegoistic extreme of thought exhibits the same paradox as the other extreme of materialism. It is equally complete in theory and equally crippling in practice. For the sake of simplicity, it is easier to state the notion by saying that a man can believe that he is always in a dream. Now, obviously there can be no positive proof given to him that he is not in a dream, for the simple reason that no proof can be offered that might not be offered in a dream. But if the man began to burn down London and say that his housekeeper would soon call him to breakfast, we should take him and put him with other logicians in a place which has often been alluded to in the course of this chapter. The man who cannot believe his senses, and the man who cannot believe anything else, are both insane, but their insanity is proved not by any error in their argument, but by the manifest mistake of their whole lives. They have both locked themselves up in two boxes, painted inside with the sun and stars; they are both unable to get out, the one into the health and happiness of heaven, the other even into the health and happiness of the earth. Their position is quite reasonable; nay, in a sense it is infinitely reasonable, just as a threepenny bit is infinitely circular. But there is such a thing as a mean infinity, a base and slavish eternity. It is amusing to notice that many of the moderns, whether sceptics or mystics, have taken as their sign a certain eastern symbol, which is the very symbol of this ultimate nullity. When they wish to represent eternity, they represent it by a serpent with his tail in his mouth. There is a startling sarcasm in the image of that very unsatisfactory meal. The eternity of the material fatalists, the eternity of the eastern pessimists, the eternity of the supercilious theosophists and higher scientists of to-day is, indeed, very well presented by a serpent eating his tail, a degraded animal who destroys even himself.
