...I want to engage you in a discussion of the deep history of beauty. By deep I mean as seen from an evolutionary perspective. I am an "evolutionary psychologist". I believe that to understand and fully appreciate human mental traits, we need to know why they are there — which is to say what biological function they are serving. Evolutionary psychology has been making pretty good progress. But, as we say, "there are still some elephants in the living room" — big issues that no one wants to talk about. And human beings worship of the beautiful remains one of the biggest.
