What the denouncer of dogma really means is not that dogma is bad; but rather that dogma is too good to be true. That is, he means that dogma is too liberal to be likely. Dogma gives man too much freedom when it permits him to fall. Dogma gives even God too much freedom when it permits him to die. That is what the intelligent sceptics ought to say; and it is not in the least my intention to deny that there is something to be said for it. They mean that the universe is itself a universal prison; that existence itself is a limitation and a control; and it is not for nothing that they call causation a chain. In a word, they mean quite simply that they cannot believe these things; not in the least that they are unworthy of belief. 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 moral of all this is an old one; that religion is revelation. In other words, it is a vision, and a vision received by faith; but it is a vision of reality. The faith consists in a conviction of its reality. That, for example, is the difference between a vision and a day-dream. And that is the difference between religion and mythology. That is the difference between faith and all that fancy-work, quite human and more or less healthy, which we considered under the head of mythology. There is something in the reasonable use of the very word vision that implies two things about it; first that it comes very rarely, possibly that it comes only once; and secondly that it probably comes once and for all. A day-dream may come every day. A day-dream may be different every day. It is something more than the difference between telling ghost-stories and meeting a ghost.
