That realization makes less shocking to me, albeit utterly dismaying, the many dogmatic behaviors exhibited today that seem outwardly irrational or close to it. The kinds of things that make it seem as if so many of us are, so to speak, losing it are actually signs of how difficult it can be to get past what we seem to be hard-wired for. Fanatic beliefs, furious ideologies and even, potentially, a sense of duty to harm people in the name of certain beliefs reflect the eternal temptation of a sense of belonging to a group, of being part of a larger story, of having a guiding sense of purpose.
