Why do we have schizophrenia in every culture on this planet? From an evolutionary perspective, schizophrenia is not a cool thing to have. ... Schizophrenia is not an adaptive trait. You can show this formally: schizophrenics have a lower rate of leaving copies of their genes in the next generation than unaffected siblings. By the rules, by the economics of evolution, this is a maladaptive trait. Yet, it chugs along at a one to two percent rate in every culture on this planet. So what's the adaptive advantage of schizophrenia? It has to do with a classic truism — this business that sometimes you have a genetic trait which in the full-blown version is a disaster, but the partial version is good news.

Additional quotes by Robert Sapolsky

Ecosystems majorly shape culture — but then that culture can be exported and persist in radically different places for millennia. Stated most straightforwardly, most of earth’s humans have inherited their beliefs about the nature of birth and death and everything in between and thereafter from preliterate Middle Eastern pastoralists.

The purpose of science in understanding who we are as humans is not to rob us of our sense of mystery, not to cure us of our sense of mystery. The purpose of science is to constantly reinvent and reinvigorate that mystery. To always use it in a context where we are helping people in trying to resist the forces of ideology that we are all familiar with.
