What does science say about aesthetics? Why isn't everyone just having missionary sex for procreation, cooking basic food and not treating cooking as an art, doing something practical, etc? What is it that makes people create literature, art, music, film, etc? Why was a piece of music like this made? https://www.youtube.com/watch?v=Hp0yVCh5OKM

Why is such a major part of our lives, or if not basically our entire lives, our aesthetic sensibilities, being ignored in science?
