Strong point you have there. But, there are still a lot of things that just feels “something” but cannot be understood as to why of it. The example you gave of the human anatomy according to me, doesn’t relate to this paragraph is because, human anatomy is worldly recognised. Its MEANT to be that way. So, people know that something is off. But, “art” isn’t MEANT to be any particular form. Its abstract. It depends on your mood. A colorful potrait might feel good at times but some other time or to some other person it might not.
I hope what I said contributed to a valuable discussion.
