Daniel Dennett has come to realize that the brain works in pretty much the same way as Hayek argued spontaneous orders work -- including the brain. The conflicts which arise among the neurons and the genes are precisely the kind I learned from J.T. Fraser underlie all complex processes.
Indeed, it turns out that if you understand how humans as agents interact in complex, self-organizing networks, you have a pretty good idea of how neurons interact in the brain. Hayek would not be surprised. Neither am I.
