It is true that in the absence of an instinctive reaction we can still apply these epithets by an appeal to usage. We may agree that an action is bad, or a building good, because we recognize in them a character which we have learned to designate by that adjective; but unless there is in us some trace of passionate reprobation or of sensible delight, there is no moral or aesthetic judgment. It is all a question of propriety of speech, and of the empty titles of things. The verbal and mechanical proposition, that passes for judgment of worth, is the great cloak of ineptitude in these matters. Insensibility is very quick in the conventional use of words. If we appealed more often to actual feeling, our judgments would be more diverse, but they would be more legitimate and instructive. Verbal judgments are often useful instruments of thought, but it is not by them that worth can ultimately be determined. Values spring from the immediate and inexplicable reaction of vital impulse, and from the irrational part of our nature. The rational part is by its essence relative; it leads us from data to conclusions, or from parts to wholes; it never furnishes the data with which it works. If any preference or precept were declared to be ultimate and primitive, it would thereby be declared to be irrational, since mediation, inference, and synthesis are the essence of rationality. The ideal of rationality is itself as arbitrary, as much dependent on the needs of a finite organization, as any other ideal. Only as ultimately securing tranquillity of mind, which the philosopher instinctively pursues, has it for him any necessity. In spite of the verbal propriety of saying that reason demands rationality, what really demands rationality, what makes it a good and indispensable thing and gives it all its authority, is not its own nature, but our need of it both in safe and economical action and in the pleasures of comprehension. It is evident that beauty is a species of value, and what we have said of value in general applies to this particular kind. A first approach to a definition of beauty has therefore been made by the exclusion of all intellectual judgments, all judgments of matter of fact or of relation. To substitute judgments of fact for judgments of value, is a sign of a pedantic and borrowed criticism. If we approach a work of art or nature scientifically, for the sake of its historical connexions or proper classification, we do not approach it aesthetically. The discovery of its date or of its author may be otherwise interesting; it only remotely affects our aesthetic appreciation by adding to the direct effect certain associations. If the direct effect were absent, and the object in itself uninteresting, the circumstances would be immaterial. Moliere's _Misanthrope_ says to the court poet who commends his sonnet as written in a quarter of an hour, Voyons, monsieur, le temps ne fait rien a l'affaire,
