coevolution

Of course, even before Flaubert, people knew stupidity existed, but they understood it somewhat differently: it was considered a simple absence of knowledge, a defect correctable by education. In Flaubert's novels, stupidity is an inseparable dimension of human existence. It accompanies poor Emma throughout her days, to her bed of love and to her deathbed, over which two deadly agélastes, Homais and Bournisien, go on endlessly trading their inanities like a kind of funeral oration. But the most shocking, the most scandalous thing about Flaubert's vision of stupidity is this: Stupidity does not give way to science, technology, modernity, progress; on the contrary, it progresses right along with progress!

In a Fisherian world, animals are slaves to evolutionary fashion, evolving extravagant and arbitrary displays and tastes that are all "meaningless"; they do not involve anything other than perceived qualities.
