The Summary: "A Darwinian theory of beauty"

In this lecture, it says that people have different ideas or opinions beauty depending on their values and cultures. But in Denis Dutton's theory, there are universal beauties which belongs to our human psychology; furthermore, there are natural selection and sexual selection in common. These selections are never changed since human beings are living; for example, people like a landscape like Venice even some poeple don't have the scene in their countries. This is the example of natural beauty. In artistic beauty, on the other hand, he says there is no universal beauty. But people also find the beauty in something done well. In conclusion, beauty is not from eyes, but is from "deep in our mind", and it is "a gift from our ancestors".
