In the red circle of the desert, in the dark and secret place, the prophet discovers the obvious things. I do not say it merely as a sneer, for obvious things are very easily forgotten; and indeed every high civilisation decays by forgetting obvious things. But it is true that in such a solitude men tend to take very simple ideas as if they were entirely new ideas. There is a love of concentration which comes from the lack of comparison. The lonely man looking at the lonely palm-tree does see the elementary truths about the palm-tree; and the elementary truths are very essential. Thus he does see that though the palm-tree may be a very simple design, it was not he who designed it. It may look like a tree drawn by a child, but he is not the child who could draw it. He has not command of that magic slate on which the pictures can come to life, or of that magic green chalk of which the green lines can grow. He sees at once that a power is at work in whose presence he and the palm-tree are alike little children. In other words, he is intelligent enough to believe in God; and the Moslem, the man of the desert, is intelligent enough to believe in God. But his belief is lacking in that humane complexity that comes from comparison. The man looking at the palm-tree does realise the simple fact that God made it; while the man looking at the lamp-post in a large modern city can be persuaded by a hundred sophistical circumlocutions that he made it himself. But the man in the desert cannot compare the palm-tree with the lamp-post, or even with all the other trees which may be better worth looking at than the lamp-post. Hence his religion, though true as far as it goes, has not the variety and vitality of the churches that were designed by men walking in the woods and orchards. I speak here of the Moslem type of religion and not of the oriental type of ornament, which is much older than the Moslem type of religion. But even the oriental type of ornament, admirable as it often is, is to the ornament of a gothic cathedral what a fossil forest is to a forest full of birds. In short, the man of the desert tends to simplify too much, and to take his first truth for the last truth. And as it is with religion so it is with morality. He who believes in the existence of God believes in the equality of man. And it has been one of the merits of the Moslem faith that it felt men as men, and was not incapable of welcoming men of many different races. But here again it was so hard and crude that its very equality was like a desert rather than a field. Its very humanity was inhuman.
