Let us for a moment put aside our own intellectual prejudices, our preconceptions, and follow Mr. Chesterton along his path of common sense. He himself, in his book on _Orthodoxy_, throws over the intellectuals. It is not that he refutes them--that would be a denial of his own method; nor that he has completely studied them--that would be a denial of his own character; but he does show us what havoc their methods may work upon the mind, what an overthrow of our workaday notions, our most vivid and keen impressions. If all the things that we seem to know the best, the emotions most natural to men "fighting peoples or proud mothers, or first love or fear upon the sea"--if all these things stand for nothing, if they are not to be thought about by our philosophers, what have we got left? The cosmos? "The cosmos is about the smallest hole that a man can hide his head in." He finds that the great popular thinkers--and it is right that he, a potent popular writer, should concern himself with these rather than with the systematic philosophers who observe conventions incomprehensible to the common mind--are each and all of them prone to follow exclusively some strange bent of thought, leading by pure reason to one of those awful conclusions which "tend to make a man lose his wits:" Tolstoy, for instance, reaching an unthinkable doctrine of self-sacrifice, Nietzsche an equally unthinkable doctrine of egoism, Ibsen, Haeckel, Mr. Shaw, Mr. McCabe--that never-to-be-forgotten Mr. McCabe--each of them by sheer force of logic betrayed into insanity.
Just as I am affected by the maniac, so I am affected by most modern thinkers. That unmistakable mood or note that I hear from Hanwell, I hear also from half the chairs of science and seats of learning to-day; and most of the mad doctors are mad doctors in more senses than one. They all have exactly that combination we have noted; the combination of one expansive and exhaustive reason with a contracted common sense. They are universal only in the sense that they take one thin explanation and carry it very far. But a pattern can stretch for ever and still be a small pattern. They see a chess-board white on black, and if the universe is paved with it, it is still white on black. Like the lunatic, they cannot alter their standpoint, they cannot make a mental effort and suddenly see it black on white.
