art in its entire completeness much science is requisite; e.g. a knowledge of ancient languages, a learned familiarity with classical authors, history, a knowledge of antiquities, etc. And hence these historical sciences, because they form the necessary preparation and basis for beautiful art, and also partly because under them is included the knowledge of the products of beautiful art (rhetoric and poetry), have come to be called beautiful sciences by a confusion of words.
If art which is adequate to the cognition of a possible object performs the actions requisite therefore merely in order to make it actual, it is mechanical art; but if it has for its immediate design the feeling of pleasure, it is called aesthetical art. This is again either pleasant or beautiful.
