There are many special or “cross-filed” chains of abstractions (of interconnected concepts) in man’s mind. Cognitive abstractions are the fundamental chain, on which all the others depend. Such chains are mental integrations, serving a special purpose and formed accordingly by a special criterion.
Cognitive abstractions are formed by the criterion of: what is essential? (epistemologically essential to distinguish one class of existents from all others). Normative abstractions are formed by the criterion of: what is good? Esthetic abstractions are formed by the criterion of: what is important?
An artist does not fake reality—he stylizes it. He selects those aspects of existence which he regards as metaphysically significant—and by isolating and stressing them, by omitting the insignificant and accidental, he presents his view of existence. His concepts are not divorced from the facts of reality—they are concepts which integrate the facts and his metaphysical evaluation of the facts. His selection constitutes his evaluation: everything included in a work of art—from theme to subject to brushstroke or adjective—acquires metaphysical significance by the mere fact of being included, of being important enough to include.
An artist (as, for instance, the sculptors of Ancient Greece) who presents man as a god-like figure is aware of the fact that men may be crippled or diseased or helpless; but he regards these conditions as accidental, as irrelevant to the essential nature of man—and he presents a figure embodying strength, beauty, intelligence, self-confidence, as man’s proper, natural state.
An artist (as, for instance, the sculptors of the Middle Ages) who presents man as a deformed monstrosity is aware of the fact that there are men who are healthy, happy or confident; but he regards these conditions as accidental or illusory, as irrelevant to man’s essential nature—and he presents a tortured figure embodying pain, ugliness, terror, as man’s proper, natural state.
