This clearing up can be accomplished only in closest touch with the actual experience of beauty; it must be performed upon our working preferences and judgments. It must be an interpretation of the actual history of art. There is no a priori method of establishing aesthetic standards. Just as no one can discover his life purpose apart from the process of living, or the purpose of another except through sympathy; so no one can know the meaning of art except through creating and enjoying and entering into the aesthetic life of other artists and art lovers.
This so-called normative—perhaps better, critical—moment in aesthetics introduces an inevitable personal element into every discussion of the subject. Even as every artist seeks to convince his public that what he offers is beautiful, so every philosopher of art undertakes to persuade of the validity of his own preferences. I would not make any secret of this with regard to the following pages of this book. Yet this intrusion of personality need not be harmful, but may, on the contrary, be valuable. It cannot be harmful if the writer proceeds undogmatically, making constant appeals to the judgment of his readers and claiming no authority for his statements except in so far as they find favor there. Influence rather than authority is what he should seek. In presenting his views, as he must, he should strive to stimulate the reader to make a clear and consistent formulation of his own preferences rather than to impose upon him standards ready made. And the good of the personal element comes from the power which one strong preference or conviction has of calling forth another, and compelling it to the discovery and defense of its grounds.
In so far as aesthetics is studied by the objective method it is a branch of psychology. Aesthetic facts are mental facts. A work of art, no matter how material it may at first seem to be, exists only as perceived and enjoyed. The marble statue is beautiful only when it enters into and becomes alive in the experience of the beholder. Keys and strings and vibrations of the air are but stimuli for the auditory experience which is the real nocturne or etude. Ether vibrations and the retina upon which they impinge are nothing more than instruments for the production of the colors which, together with the interpretation of them in terms of ideas and feelings, constitute the real picture which we appreciate and judge. The physical stimuli and the physiological reactions evoked by them are important for our purpose only so far as they help us to understand the inner experiences with which they are correlated. A large part of our work, therefore, will consist in the psychological analysis of the experience of art and the motives underlying its production. We shall have to distinguish the elements of mind that enter into it, show their interrelations, and differentiate the total experience from other types of experience. Since, moreover, art is a social phenomenon, we shall have to draw upon our knowledge of social psychology to illumine our analysis of the individual's experience. Art is a historical, even a technical, development; hence the personal enjoyment of beauty itself is conditioned by factors that spring from the traditions of groups of artists and art lovers. No one can understand his pleasure in beauty apart from the pleasure of others.
In so far, on the other hand, as aesthetics is an attempt to define the purpose of art and so to formulate the standards presupposed in judgments of taste, it is closely related to criticism. The relation is essentially that between theory and the application of theory. It is the office of the critic to deepen and diffuse the appreciation of particular works of art. For this purpose he must possess standards; but he need not be, and in fact often is not, aware of them. A fine taste may serve his ends. Not infrequently, however, the critic endeavors to make clear to himself and his readers the principles he is employing. Now, on its normative side, aesthetics is ideally the complete rationale of criticism, the systematic achievement, for its own sake, of what the thoughtful critic attempts with less exactness and for the direct purpose of appreciation. It is beyond the province of aesthetics to criticize any particular work of art, except by way of illustration. The importance of illustration for the sake of explaining and proving general principles is, however, fundamental; for, as we have seen, a valuable aesthetic theory is impossible unless developed out of the primary aesthetic life of enjoyment and estimation, a life of contact with individual beautiful things. No amount of psychological skill in analysis or philosophical aptitude for definition can compensate for want of a real love of beauty,—of the possession of something of the artistic temperament. People who do not love art, yet study it from the outside, may contribute to our knowledge of it through isolated bits of analysis, but their interpretations of its more fundamental nature are always superficial. Hence, just as the wise critic will not neglect aesthetics, so the philosopher of art should be something of a critic. Yet the division of labor is clear enough. The critic devotes himself to the appreciation of some special contemporary or historical field of art—Shakespearean drama, Renaissance sculpture, Italian painting, for example; while the philosopher of art looks for general principles, and gives attention to individual works of art and historical movements only for the purpose of discovering and illustrating them. And, since the philosopher of art seeks a universal idea of art rather than an understanding of this or that particular work of art, an intimate acquaintance with a few examples, through which this idea can be revealed to the loving eye, is of more importance than a wide but superficial aesthetic culture.
In our discussion thus far, we have been assuming the possibility of aesthetic theory. But what shall we say in answer to the mystic who tells us that beauty is indefinable? First of all, I think, we should remind him that his own thesis can be proved or refuted only through an attempt at a scientific investigation of beauty. Every attempt to master our experience through thought is an adventure; but the futility of adventures can be shown only by courageously entering into them. And, although the failure of previous efforts may lessen the probabilities of success in a new enterprise, it cannot prove that success is absolutely impossible. Through greater persistence and better methods the new may succeed where the old have failed. Moreover, although we are ready to grant that the pathway to our goal is full of pitfalls, marked by the wreckage of old theories, yet we claim that the skeptic or the mystic can know of their existence only by traveling over the pathway himself; for in the world of the inner life nothing can be known by hearsay. If, then, he would really know that the road to theoretical insight into beauty is impassable, let him travel with us and see; or, if not with us, alone by himself or with some one wiser than we as guide; let him compare fairly and sympathetically the results of theoretical analysis and construction with the data of his firsthand experience and observe whether the one is or is not adequate to the other.
Again, the cleft between thought and feeling, even subtle and fleeting aesthetic feeling, is not so great as the mystics suppose. For, after all, there is a recognizable identity and permanence even in these feelings; we should never call them by a common name or greet them as the same despite their shiftings from moment to moment if this were not true. Although whatever is unique in each individual experience of beauty, its distinctive flavor or nuance, cannot be adequately rendered in thought, but can only be felt; yet whatever each new experience has in common with the old, whatever is universal in all aesthetic experiences, can be formulated. The relations of beauty, too, its place in the whole of life, can be discovered by thought alone; for only by thought can we hold on to the various things whose relations we are seeking to establish; without thought our experience falls asunder into separate bits and never attains to unity. Finally, the mystics forget that the life of thought and the life of feeling have a common root; they are both parts of the one life of the mind and so cannot be foreign to each other.
The motive impelling to any kind of undertaking is usually complex, and that which leads to the development of aesthetic theory is no exception to the general rule. A disinterested love of understanding has certainly played a part. Every region of experience invites to the play of intelligence upon it; the lover of knowledge, as Plato says, loves the whole of his object. Yet even intelligence, insatiable and impartial as it is, has its predilections. The desire to understand a particular type of thing has its roots in an initial love of it. As the born botanist is the man who finds joy in contact with tree and moss and mushroom, so the student of aesthetics is commonly a lover of beauty. And, although the interest which he takes in aesthetic theory is largely just the pleasure in possessing clear ideas, one may question whether he would pursue it with such ardor except for the continual lover's touch with picture and statue and poem which it demands. For the intelligent lover of beauty, aesthetic theory requires no justification; it is as necessary and pleasurable for him to understand art as it is compulsive for him to seek out beautiful things to enjoy. To love without understanding is, to the thoughtful lover, an infidelity to his object. That the interest in aesthetic theory is partly rooted in feeling is shown from the fact that, when developed by artists, it takes the form of a defense of the type of art which they are producing. The aesthetic theory of the German Romanticists is an illustration of this; Hebbel and Wagner are other striking examples. These men could not rest until they had put into communicable and persuasive form the aesthetic values which they felt in creation. And we, too, who are not artists but only lovers of beauty, find in theory a satisfaction for a similar need with reference to our preferences.[Footnote: Compare Santayana: The Sense of Beauty, p. 11.]
More important to the average man is the help which aesthetic theory may render to appreciation itself. If to the basal interest in beauty be added an interest in understanding beauty, the former is quickened and fortified and the total measure of enjoyment increased. Even the love of beauty, strong as it commonly is, may well find support through connection with an equally powerful and enduring affection. The aesthetic interest is no exception to the general truth that each part of the mind gains in stability and intensity if connected with the others; isolated, it runs the risk of gradual decay in satiety or through the crowding out of other competing interests, which if joined with it, would have kept it alive instead. Moreover, the understanding of art may increase the appreciation of particular works of art. For the analysis and constant attention to the subtler details demanded by theory may bring to notice aspects of a work of art which do not exist for an unthinking appreciation. As a rule, the appreciations of the average man are very inadequate to the total possibilities offered, extending only to the more obvious features. Often enough besides, through a mere lack of understanding of the purpose of art in general and of the more special aims of the particular arts, people expect to find what cannot be given, and hence are prejudiced against what they might otherwise enjoy. The following pages will afford, I hope, abundant illustrations of this truth.
Finally, aesthetic theory may have a favorable influence upon the creation of art. Not that the student of aesthetics can prescribe to the artist what he shall or shall not do; for the latter can obey, for better or worse, only the inner imperative of his native genius. Yet, inevitably, the man of genius receives direction and cultivation from the aesthetic sentiment of the time into which he is born and grown; even when he reacts against it, he nevertheless feels its influence; a sound conception of the nature and purpose of art may save him from many mistakes. The French classical tradition in sculpture and painting, which is not merely academic, having become a part of public taste, prevented the production of the frightful crudities which passed for art in Germany and England during the present and past centuries. By helping to create a freer and more intelligent atmosphere for the artist to be born and educated in, and finer demands upon him when once he has begun to produce and is seeking recognition, the student of aesthetics may indirectly do not a little for him. And surely in our own country, where an educated public taste does not exist and the fiercest prejudices are rampant, there is abundant opportunity for service.
