Robin I.M. Dunbar

“It's perhaps not so much how your amygdala is tuned that makes you politically extreme, but that your intrinsic nervousness makes you more responsive to things that might seem to threaten your particular social world. Education probably plays an important role in dampening that response by allowing the brain's frontal lobes (where much of the brain's conscious work goes on) to counteract the emotional responses with a more considered view, so explaining why education is invariably the friend of liberal politics.”
― Robin Dunbar, How Many Friends Does One Person Need?

“There are probably two key aspects of culture that stand out as being uniquely human. One is religion and the other is story-telling. There is no other living species, whether ape or crow, that do either of these. They are entirely and genuinely unique to humans.”
― Robin Dunbar, Human Evolution: A Pelican Introduction
