To contribute more to the topic; a Randian view on modern art. This is from @the-ego-is-you
Rand liked to keep strict definitions, as she valued logical coherence.
She thus didn’t accept the concept of the so called “modern art” as any kind of real art, even if she recognized that there could still be a smaller artistic aspect to a piece or its creation.
Leonard Peikoff did a very brief and informative show where he defined and discussed the subject together with a fellow objectivist art historian. (The below video clip is actually the last out of 4 parts)
