The theme or content cannot, therefore, be practically or morally charged with epithets of praise or blame. When critics of art remark that a theme is _badly selected,_ in cases where that observation has a just foundation, it is a question of blaming, not the selection of the theme (which would be absurd), but the manner in which the artist has treated it, the failure of the expression due to the contradictions which it contains. And when the same critics object to the theme or content of works which they proclaim to be artistically perfect as being unworthy of art and blameworthy; if these expressions really are perfect, there is nothing to be done but to advise the critics to leave the artists in peace, for they can only derive inspiration from what has moved their soul. They should rather direct their attention towards effecting changes in surrounding nature and society, that such impressions and states of soul should not recur. If ugliness were to vanish from the world, if universal virtue and felicity were established there, perhaps artists would no longer represent perverse or pessimistic feelings, but calm, innocent and joyous feelings, Arcadians of a real Arcady. But so long as ugliness and turpitude exist in nature and impose themselves upon the artist, to prevent the expression of these things also is impossible; and when it has arisen, _factum infectum fieri nequit._ We speak thus entirely from the æsthetic point of view, and of pure criticism of art. We are not concerned to estimate the damage which the criticism of "choice" does to artistic production, with the prejudices which it produces or maintains among the artists themselves, and with the conflict to which it gives rise between artistic impulse and critical demands. It is true that sometimes it seems also to do some good, by aiding artists to discover themselves, that is, their own impressions and their own inspiration, and to acquire consciousness of the task which is, as it were, imposed upon them by the historical moment in which they live, and by their individual temperament. In these cases, criticism of "choice," while believing that it generates, merely recognizes and aids the expressions which are already being formed. It believes itself to be the mother, where, at most, it is only the midwife. [Sidenote: _The independence of art._] The impossibility of choice of content completes the theorem of the _independence of art,_ and is also the only legitimate meaning of the expression: _art for art's sake._ Art is independent both of science and of the useful and the moral. There should be no fear lest frivolous or cold art should thus be justified, since what is truly frivolous or cold is so because it has not been raised to expression; or in other words, frivolity and frigidity come always from the form of the æsthetic treatment, from failure to grasp a content, not from the material qualities of the content itself.
