What is the function of beauty in art?

“It is [the] spiritual and evolutionary function of beauty—the power to generate life-affirming change—that is so vital to the visual arts and culture in general, and it is what is intentionally absent in much postmodern art…. Restoring the centrality of beauty in art may signal more than visual relief from the tawdriness of today’s art. It would also be a confident assertion that the future we seek is connected to our desire for beauty and to an appreciation of how beauty can help lead us to a more perfect tomorrow.”                   by Carol Ann Raphael       “The Beauty We Create”
