To criticise a work of art historically is to play the science-besotted fool. No more disastrous theory ever issued from the brain of a charlatan than that of evolution in art. Giotto did not creep, a grub, that Titian might flaunt, a butterfly. To think of a man's art as leading on to the art of someone else is to misunderstand it. To praise or abuse or be interested in a work of art because it leads or does not lead to another work of art is to treat it as though it were not a work of art. The connection of one work of art with another may have everything to do with history: it has nothing to do with appreciation. So soon as we begin to consider a work as anything else than an end in itself we leave the world of art. Though the development of painting from Giotto to Titian may be interesting historically, it cannot affect the value of any particular picture: aesthetically, it is of no consequence whatever. Every work of art must be judged on its own merits.
Therefore, be sure that, in my next chapter, I am not going to make aesthetic judgments in the light of history; I am going to read history in the light of aesthetic judgments. Having made my judgments, independently of any theory, aesthetic or non-aesthetic, I shall be amused to see how far the view of history that may be based on them agrees with accepted historical hypotheses. If my judgments and the dates furnished by historians be correct, it will follow that some ages have produced more good art than others: but, indeed, it is not disputed that the variety in the artistic significance of different ages is immense. I shall be curious to see what relation can be established between the art and the age that produced it. If my second hypothesis—that art is the expression of an emotion for ultimate reality—be correct, the relation between art and its age will be inevitable and intimate. In that case, an aesthetic judgment will imply some sort of judgment about the general state of mind of the artist and his admirers. In fact, anyone who accepts absolutely my second hypothesis with all its possible implications—which is more than I am willing to do—will not only see in the history of art the spiritual history of the race, but will be quite unable to think of one without thinking of the other.
If I do not go quite so far as that, I stop short only by a little. Certainly it is less absurd to see in art the key to history than to imagine that history can help us to an appreciation of art. In ages of spiritual fervour I look for great art. By ages of spiritual fervour I do not mean pleasant or romantic or humane or enlightened ages; I mean ages in which, for one reason or another, men have been unusually excited about their souls and unusually indifferent about their bodies. Such ages, as often as not, have been superstitious and cruel. Preoccupation with the soul may lead to superstition, indifference about the body to cruelty. I never said that ages of great art were sympathetic to the middle-classes. Art and a quiet life are incompatible I think; some stress and turmoil there must be. Need I add that in the snuggest age of materialism great artists may arise and flourish? Of course: but when the production of good art is at all widespread and continuous, near at hand I shall expect to find a restless generation. Also, having marked a period of spiritual stir, I shall look, not far off, for its manifestation in significant form. But the stir must be spiritual and genuine; a swirl of emotionalism or political frenzy will provoke nothing fine.[8] How far in any particular age the production of art is stimulated by general exaltation, or general exaltation by works of art, is a question hardly to be decided. Wisest, perhaps, is he who says that the two seem to have been interdependent. Just how dependent I believe them to have been, will appear when, in my next chapter, I attempt to sketch the rise, decline, and fall of the Christian slope.

ART AND ETHICS
Between me and the pleasant places of history remains, however, one ugly barrier. I cannot dabble and paddle in the pools and shallows of the past until I have answered a question so absurd that the nicest people never tire of asking it: "What is the moral justification of art?" Of course they are right who insist that the creation of art must be justified on ethical grounds: all human activities must be so justified. It is the philosopher's privilege to call upon the artist to show that what he is about is either good in itself or a means to good. It is the artist's duty to reply: "Art is good because it exalts to a state of ecstasy better far than anything a benumbed moralist can even guess at; so shut up." Philosophically he is quite right; only, philosophy is not so simple as that. Let us try to answer philosophically.
The moralist inquires whether art is either good in itself or a means to good. Before answering, we will ask what he means by the word "good," not because it is in the least doubtful, but to make him think. In fact, Mr. G.E. Moore has shown pretty conclusively in his Principia Ethica that by "good" everyone means just good. We all know quite well what we mean though we cannot define it. "Good" can no more be defined than "Red": no quality can be defined. Nevertheless we know perfectly well what we mean when we say that a thing is "good" or "red." This is so obviously true that its statement has greatly disconcerted, not to say enraged, the orthodox philosophers.
Orthodox philosophers are by no means agreed as to what we do mean by "good," only they are sure that we cannot mean what we say. They used to be fond of assuming that "good" meant pleasure; or, at any rate, that pleasure was the sole good as an end: two very different propositions. That "good" means "pleasure" and that pleasure is the sole good was the opinion of the Hedonists, and is still the opinion of any Utilitarians who may have lingered on into the twentieth century. They enjoy the honour of being the only ethical fallacies worth the powder and shot of a writer on art. I can imagine no more delicate or convincing piece of logic than that by which Mr. G.E. Moore disposes of both. But it is none of my business to do clumsily what Mr. Moore has done exquisitely. I have no mind by attempting to reproduce his dialectic to incur the merited ridicule of those familiar with the Principia Ethica or to spoil the pleasure of those who will be wise enough to run out this very minute and order a masterpiece with which they happen to be unacquainted. For my immediate purpose it is necessary only to borrow one shaft from that well-stocked armoury.
