G. K. Chesterton’s explanation of on what evidences he accepts the claims of Christianity was too compelling and too thorough to summarize or to quote only in part. Here is his extended argument quoted in at length:
If I am asked, as a purely intellectual question, why I believe in Christianity, I can only answer, “For the same reason that an intelligent agnostic disbelieves in Christianity.” I believe in it quite rationally upon the evidence. But the evidence in my case, as in that of the intelligent agnostic, is not really in this or that alleged demonstration; it is in an enormous accumulation of small but unanimous facts. The secularist is not to be blamed because his objections to Christianity are miscellaneous and even scrappy; it is precisely such scrappy evidence that does convince the mind. I mean that a man may well be less convinced of a philosophy from four books, than from one book, one battle, one landscape, and one old friend. The very fact that the things are of different kinds increases the importance of the fact that they all point to one conclusion.
Now, the non-Christianity of the average educated man to-day is almost always, to do him justice, made up of these loose but living experiences. I can only say that my evidences for Christianity are of the same vivid but varied kind as his evidences against it. For when I look at these various anti-Christian truths, I simply discover that none of them are true. I discover that the true tide and force of all the facts flows the other way. Let us take cases.
Many a sensible modern man must have abandoned Christianity under the pressure of three such converging convictions as these: first, that men, with their shape, structure, and sexuality, are, after all, very much like beasts, a mere variety of the animal kingdom; second, that primeval religion arose in ignorance and fear; third, that priests have blighted societies with bitterness and gloom. Those three anti-Christian arguments are very different; but they are all quite logical and legitimate; and they all converge. The only objection to them (I discover) is that they are all untrue.
If you leave off looking at books about beasts and men, if you begin to look at beasts and men then (if you have any humour or imagination, any sense of the frantic or the farcical) you will observe that the startling thing is not how like man is to the brutes, but how unlike he is. It is the monstrous scale of his divergence that requires an explanation. That man and brute are like is, in a sense, a truism; but that being so like they should then be so insanely unlike, that is the shock and the enigma. That an ape has hands is far less interesting to the philosopher than the fact that having hands he does next to nothing with them; does not play knuckle-bones or the violin; does not carve marble or carve mutton. People talk of barbaric architecture and debased art. But elephants do not build colossal temples of ivory even in a roccoco style; camels do not paint even bad pictures, though equipped with the material of many camel’s-hair brushes. Certain modern dreamers say that ants and bees have a society superior to ours. They have, indeed, a civilization; but that very truth only reminds us that it is an inferior civilization. Who ever found an ant-hill decorated with the statues of celebrated ants? Who has seen a bee-hive carved with the images of gorgeous queens of old?
No; the chasm between man and other creatures may have a natural explanation, but it is a chasm. We talk of wild animals; but man is the only wild animal. It is man that has broken out. All other animals are tame animals; following the rugged respectability of the tribe or type. All other animals are domestic animals; man alone is ever undomestic, either as a profligate or a monk. So that this first superficial reason for materialism is, if anything, a reason for its opposite; it is exactly where biology leaves off that all religion begins.
He concludes thus:
This, therefore, is, in conclusion, my reason for accepting the religion and not merely the scattered and secular truths out of the religion. I do it because the thing has not merely told this truth or that truth, but has revealed itself as a truth-telling thing. All other philosophies say the things that plainly seem to be true; only this philosophy has again and again said the thing that does not seem to be true, but is true. Alone of all creeds it is convincing where it is not attractive
