The whole history of the thing called rhyme can be found between those two things: the simple pleasure of rhyming “diddle” to “fiddle,” and the more sophisticated pleasure of rhyming “diddle” to “idyll.” Now the fatal mistake about poetry, and more than half of the fatal mistake about humanity, consists in forgetting that we should have the first kind of pleasure as well as the second. It might be said that we should have the first pleasure as the basis of the second; or yet more truly, the first pleasure inside the second. The fatal metaphor of progress, which means leaving things behind us, has utterly obscured the real idea of growth, which means leaving things inside us. The heart of the tree remains the same, however many rings are added to it; and a man cannot leave his heart behind by running hard with his legs. In the core of all culture are the things that may be said, in every sense, to be learned by heart. In the innermost part of all poetry is the nursery rhyme, the nonsense that is too happy even to care about being nonsensical. It may lead on to the more elaborate nonsense of the Gilbertian line, or even the far less poetic nonsense of some of the Browningesque rhymes. But the true enjoyment of poetry is always in having the simple pleasure as well as the subtle pleasure. Indeed it is on this primary point that so many of our artistic and other reforms seem to go wrong. What is the matter with the modern world is that it is trying to get simplicity in everything except the soul. Where the soul really has simplicity it can be grateful for anything--even complexity. Many peasants have to be vegetarians, and their ordinary life is really a simple life. But the peasants do not despise a good dinner when they can get it; they wolf it down with enthusiasm, because they have not only the simple life but the simple spirit. And it is so with the modern modes of art which revert, very rightly, to what is “primitive.” But their moral mistake is that they try to combine the ruggedness that should belong to simplicity with a superciliousness that should only belong to satiety. The last Futurist draughtsmanship, for instance, evidently has the aim of drawing a tree as it might be drawn by a child of ten. I think the new artists would admit it; nor do I merely sneer at it. I am willing to admit, especially for the sake of argument, that there is a truth of philosophy and psychology in this attempt to attain the clarity even through the crudity of childhood. In this sense I can see what a man is driving at when he draws a tree merely as a stick with smaller sticks standing out of it. He may be trying to trace in black and white or grey a primeval and almost prenatal illumination; that it is very remarkable that a stick should exist, and still more remarkable that a stick should stick up or stick out. He may be similarly enchanted with his own stick of charcoal or grey chalk; he may be enraptured, as a child is, with the
