All the existing æsthetic standards are built on this plan. Instead of giving a definition of true art, and then deciding what is and what is not good art by judging whether a work conforms or does not conform to the definition, a certain class of works, which for some reason please a certain circle of people, is accepted as being art, and a definition of art is then devised to cover all these productions. I recently came upon a remarkable instance of this method in a very good German work, _The History of Art in the Nineteenth Century_, by Muther. Describing the pre-Raphaelites, the Decadents and the Symbolists (who are already included in the canon of art), he not only does not venture to blame their tendency, but earnestly endeavours to widen his standard so that it may include them all, they appearing to him to represent a legitimate reaction from the excesses of realism. No matter what insanities appear in art, when once they find acceptance among the upper classes of our society a theory is quickly invented to explain and sanction them; just as if there had never been periods in history when certain special circles of people recognised and approved false, deformed, and insensate art which subsequently left no trace and has been utterly forgotten. And to what lengths the insanity and deformity of art may go, especially when, as in our days, it knows that it is considered infallible, may be seen by what is being done in the art of our circle to-day. So that the theory of art, founded on beauty, expounded by æsthetics, and, in dim outline, professed by the public, is nothing but the setting up as good, of that which has pleased and pleases us, _i.e._ pleases a certain class of people. In order to define any human activity, it is necessary to understand its sense and importance. And, in order to do that, it is primarily necessary to examine that activity in itself, in its dependence on its causes, and in connection with its effects, and not merely in relation to the pleasure we can get from it. If we say that the aim of any activity is merely our pleasure, and define it solely by that pleasure, our definition will evidently be a false one. But this is precisely what has occurred in the efforts to define art. Now, if we consider the food question, it will not occur to anyone to affirm that the importance of food consists in the pleasure we receive when eating it. Everyone understands that the satisfaction of our taste cannot serve as a basis for our definition of the merits of food, and that we have therefore no right to presuppose that the dinners with cayenne pepper, Limburg cheese, alcohol, etc., to which we are accustomed and which please us, form the very best human food. And in the same way, beauty, or that which pleases us, can in no sense serve as the basis for the definition of art; nor can a series of objects which afford us pleasure serve as the model of what art should be.
