St. Thomas Aquinas by G.K. Chesterton — Read

The fact that Thomism is the philosophy of common sense is itself a matter of common sense. Yet it wants a word of explanation, because we have so long taken such matters in a very uncommon sense. For good or evil, Europe since the Reformation, and most especially England since the Reformation, has been in a peculiar sense the home of paradox. I mean in the very peculiar sense that paradox was at home, and that men were at home with it. The most familiar example is the English boasting that they are practical because they are not logical. To an ancient Greek or a Chinaman this would seem exactly like saying that London clerks excel in adding up their ledgers, because they are not accurate in their arithmetic. But the point is not that it is a paradox; it is that parodoxy has become orthodoxy; that men repose in a paradox as placidly as in a platitude. It is not that the practical man stands on his head, which may sometimes be a stimulating if startling gymnastic; it is that he rests on his head; and even sleeps on his head. This is an important point, because the use of paradox is to awaken the mind. Take a good paradox, like that of Oliver Wendell Holmes: "Give us the luxuries of life and we will dispense with the necessities." It is amusing and therefore arresting; it has a fine air of defiance; it contains a real if romantic truth. It is all part of the fun that it is stated almost in the form of a contradiction in terms. But most people would agree that there would be considerable danger in basing the whole social system on the notion that necessities are not necessary; as some have based the whole British Constitution on the notion that nonsense will always work out as common sense. Yet even here, it might be said that the invidious example has spread, and that the modern industrial system does really say, "Give us luxuries like coal-tar soap, and we will dispense with necessities like corn."

So much is familiar; but what is not even now realised is that not only the practical politics, but the abstract philosophies of the modern world have had this queer twist. Since the modern world began in the sixteenth century, nobody's system of philosophy has really corresponded to everybody's sense of reality: to what, if left to themselves, common men would call common sense. Each started with a paradox: a peculiar point of view demanding the sacrifice of what they would call a sane point of view. That is the one thing common to Hobbes and Hegel, to Kant and Bergson, to Berkeley and William James. A man had to believe something that no normal man would believe, if it were suddenly propounded to his simplicity; as that law is above right, or right is outside reason, or things are only as we think them, or everything is relative to a reality that is not there. The modern philosopher claims, like a sort of confidence man, that if once we will grant him this, the rest will be easy; he will straighten out the world, if once he is allowed to give this one twist to the mind.
