A lot of classic art depicted the brokenness of the world. Saturn Devouring his Son, anything titled โThe Rape of theโฆโ etc. Art isnโt just about good thoughts and emotions, itโs about communicating any part of the human experience.
I do sometimes think it could be useful to categorize art into what kind of way itโs trying to communicate. Putting a urinal in a gallery space is very different from Jackson Pollock is very different from Michelangelo. But I actually get calling them all art even if some art I donโt like as much.
