A circumstance that has also contributed to the absence or to the failure of aesthetic speculation is the subjectivity of the phenomenon with which it deals. Man has a prejudice against himself: anything which is a product of his mind seems to him to be unreal or comparatively insignificant. We are satisfied only when we fancy ourselves surrounded by objects and laws independent of our nature. The ancients long speculated about the constitution of the universe before they became aware of that mind which is the instrument of all speculation. The moderns, also, even within the field of psychology, have studied first the function of perception and the theory of knowledge, by which we seem to be informed about external things; they have in comparison neglected the exclusively subjective and human department of imagination and emotion. We have still to recognize in practice the truth that from these despised feelings of ours the great world of perception derives all its value, if not also its existence. Things are interesting because we care about them, and important because we need them. Had our perceptions no connexion with our pleasures, we should soon close our eyes on this world; if our intelligence were of no service to our passions, we should come to doubt, in the lazy freedom of reverie, whether two and two make four. Yet so strong is the popular sense of the unworthiness and insignificance of things purely emotional, that those who have taken moral problems to heart and felt their dignity have often been led into attempts to discover some external right and beauty of which, our moral and aesthetic feelings should be perceptions or discoveries, just as our intellectual activity is, in men's opinion, a perception or discovery of external fact. These philosophers seem to feel that unless moral and aesthetic judgments are expressions of objective truth, and not merely expressions of human nature, they stand condemned of hopeless triviality. A judgment is not trivial, however, because it rests on human feelings; on the contrary, triviality consists in abstraction from human interests; only those judgments and opinions are truly insignificant which wander beyond the reach of verification, and have no function in the ordering and enriching of life. Both ethics and aesthetics have suffered much from the prejudice against the subjective. They have not suffered more because both have a subject-matter which is partly objective. Ethics deals with conduct as much as with emotion, and therefore considers the causes of events and their consequences as well as our judgments of their value. Esthetics also is apt to include the history and philosophy of art, and to add much descriptive and critical matter to the theory of our susceptibility to beauty. A certain confusion is thereby introduced into these inquiries, but at the same time the discussion is enlivened by excursions into neighbouring provinces, perhaps more interesting to the general reader.
