The human personality—including those aspects of it that are imaginative, expressive, and creative—cries out for a Darwinian explanation. If we're going to treat aspects of the personality, including the aesthetic expression, as adaptations, we've got to do it in terms of three factors.

Pleasure

universality

spontaneous development

We see them in the cross-cultural realities of music, the universality of storytelling, as well as things like food tastes, erotic interests, pet-keeping, sports interests, our fascination with puzzle solving, gossip

ask ourselves why the arts are universal. The notion that art is purely socially constructed

has to make way for something more complex.

Human life is lived in a middle position between our genetic determinants on the one hand and culture on the other

It's out of that that human freedom emerges

artistic works

are the ultimate expressions of freedom

It’s a great question, What is art?

Will anyone be interested in seeing them in a hundred years?
