From the very moment of your life, culture is leaving an imprint on who you are. - Robert Sapolsky

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.

Like so many other animals, we have an often-frantic need to conform, belong, and obey. Such conformity can be markedly maladaptive, as we forgo better solutions in the name of the foolishness of the crowd.

I am a reasonably emotional person, and I see no reason why that's incompatible with being a scientist. Even if we learn about how everything works, that doesn't mean anything at all. You can reduce how an impala leaps to a bunch of biomechanical equations. You can turn Bach into contrapuntal equations, and that doesn't reduce in the slightest our capacity to be moved by a gazelle leaping or Bach thundering. There is no reason to be less moved by nature around us simply because it's revealed to have more layers of complexity than we first observed. The more important reason why people shouldn't be afraid is, we're never going to inadvertently go and explain everything. We may learn everything about something, and we may learn something about everything, but we're never going to learn everything about everything. When you study science, and especially these realms of the biology of what makes us human, what's clear is that every time you find out something, that brings up ten new questions, and half of those are better questions than you started with.
