Error begins when we try to deduce the expression from the concept, and to find in what takes its place the laws of the thing whose place is taken; when the difference between the second and the first step has not been observed, and when, in consequence, we declare that we are standing on the first step, when we are really standing on the second. This error is known as the _theory of artistic and literary kinds._
"What is the _æsthetic_ form of domestic life, of chivalry, of the idyll, of cruelty, and so forth? How should these contents be _represented_?" Such is the absurd problem implied in the theory of artistic and literary classes, when it has been shorn of excrescences and reduced to a simple formula. It is in this that consists all search after laws or rules of classes. Domestic life, chivalry, idyll, cruelty and the like, are not impressions, but concepts. They are not contents, but logical-æsthetic forms. You cannot express the form, for it is already itself expression. For what are the words cruelty, idyll, chivalry, domestic life, and so on, but the expression of those concepts?
Even the most refined of such distinctions, which possess the most philosophic appearance, do not resist criticism; as when works of art are divided into subjective and objective kinds, into lyric and epic, into works of feeling and decorative works. In æsthetic analysis it is impossible to separate subjective from objective, lyric from epic, the image of feeling from that of things.
[Sidenote: _Errors derived from this theory in judgements on art._]
From the theory of artistic and literary kinds derive those erroneous modes of judgement and of criticism, thanks to which, instead of asking before a work of art if it be expressive and what it expresses, whether it speak or stammer or is altogether silent, they ask if it obey the _laws_ of epic or of tragedy, of historical painting or of landscape. While making a verbal pretence of agreeing, or yielding a feigned obedience, artists have, however, really always disregarded these _laws of the kinds._ Every true work of art has violated some established kind and upset the ideas of the critics, who have thus been obliged to broaden the kinds, until finally even the broadened kind has proved too narrow, owing to the appearance of new works of art, naturally followed by new scandals, new upsettings and--new broadenings.
