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. CHAPTER II DEFINITION OF ART
