Avant-garde and Kitsch
(Auto-generated)

But even during the Renaissance, and as long as Western art was endeavoring to perfect its technique, victories in this realm could only be signalized by success in realistic imitation, since there was no other objective criterion at hand.

objective = fact-based and not influenced by personal feelings or preferences
It has been in search of the absolute that the avant-garde has arrived at "abstract" or "nonobjective" art — and poetry, too.†

nonobjective = not fact-based; or influenced by personal feelings or preferences

standard prefix: The prefix "non-" in nonobjective means not and reverses the meaning of objective. This is the same pattern you see in words like nonfat, nonfiction, and nonprofit.

Definitions:

(1) (objective as in: our objective is to...)
a goal (some end desired to be achieved)
(2) (objective as in: an objective viewpoint)
fact-based without the influence of personal feelings or preferences

Objective is often contrasted with subjective--which means "influenced by personal belief, feelings, or preferences (rather than being based purely upon fact)."
(3) (meaning too rare to warrant focus)
Less common meanings of objective include:
- In philosophy -- existing outside of the mind.
- In grammar -- the object of a verb or of certain prepositions.
- In optics -- the lens nearest the object being viewed
