M ad. Macshaler was a em german phrenomenological philosopher who died too young. He generated what he called a sort of pyramid of values, which i have included in post books. In the bottommost level are those of utility and pleasure; above that come leben verta or values of life. And at the summit is dasliga, the holy: goodness, beauty and truth. But as diamond said, even in the sense of favouring sexual selection, that can't be the end of the story because you' still got to account for the existence of beauty.
