I think first and foremost its important to step back and look more closely at what modern art 'actually' is, and what it represents in the current art-meta.
Hopefully that wasn't too difficult to understand. In case you found it hard to comprehend easily, which is completely understandable, we recommend you study some lesser forms of art such as impressionism, surrealism, or aestheticism so that you may have a better tool kit to fully appreciate this lesson.
