"Imagine a society where, if anyone works hard enough, they can make a living and raise a family ... But that society might not be sustainable in the long run: its population might get unhealthier, or less intelligent, or less psychologically stable. "Is that dark?" Yes, it is dark as hell. Without feeding the bloodthirsty maw of evolution, deleterious alleles accumulate. That makes many things that are clearly evil, like death, necessary. Darwin's description of the world is ultimately a successful theodicy, a story that vindicates Satan. "Here's why we need evil in the world." "Here's why the optimal number of dead babies is greater than zero." What could be darker? I wish that made it wrong.
