[Sidenote: _Art as sum of content and form._]
Herbart looks on art as a complex fact, the combination of an extra-æsthetic element, content, which may have logical or psychological or any other kind of value, and a purely æsthetic element, form, which is an application of the fundamental æsthetic concepts. Man looks for that which is diverting, instructive, moving, majestic, ridiculous; and "all these are mingled with the beautiful in order to procure favour and interest for the work. The beautiful thus assumes various complexions, and becomes graceful, magnificent, tragic, or comic; it can become all these because the æsthetic judgement, in itself calmly serene, tolerates the company of the most diverse excitations of the soul which are no part of itself."[16] But all these things have nothing to do with beauty. In order to discover the objectively beautiful or ugly, one must make abstraction from every predicate concerning the content. "In order to recognize the objectively beautiful or ugly in poetry, one must show the difference between this and that thought, and the discussion will concern itself with thoughts; to recognize it in sculpture, one must show the difference between this and that outline, and the discussion will turn upon outlines; to recognize it in music, one should show the difference between this and that tone, and the discussion will turn upon tones. Now, such predicates as 'magnificent, charming, graceful' and so forth contain nothing whatever about tones, outlines or thoughts, and therefore tell us nothing about the objectively beautiful in poetry, sculpture, or music; indeed they rather lead us to believe in the existence of an objective beauty to which thought, outline, or tone are equally accidental, which may be approached by receiving impressions from poetry, sculpture, music and so forth, obliterating the object and giving oneself up to the pure emotion of mind."[17] Very different is the æsthetic judgement, the "cold judgement of the connoisseur" who considers exclusively form, _i.e._ objectively pleasant formal relations. This abstraction from the content in order to contemplate pure form is the catharsis produced by art. Content is transitory, relative, subject to moral law and liable to moral judgement: form is permanent, absolute, free.[18] Concrete art may be the sum of two or more values; but the æsthetic fact is form alone.
