Why art?

(A question similar to this one was asked three years ago. I think it can be asked again.)

What do humans gain by making art? Why do we value it?

Museums and collectors clamor for paintings and pay fortunes for some. Theaters proclaim great plays, and people stream to see them.

I travel and take in art museums and performances. I have been moved to tears by pieces of beautiful art, both visual and performing.

What does art mean to you? What do you get from it?
