Agency from individual neurons

What I’m going to argue today is that agency is a fundamental property of the brain. Not only is agency the function of the brain — and thus it’s very reason for existence — but it’s also built into the brain’s fabric and architecture. Because even neurons have agency, in the form of (metabolic) selfishness, higher-order brain systems don’t need to create agency ‘from scratch’ out of mindless robotic slaves. They inherit agency pretty much for free.

The question of agency occassionally sucks me into a deep whirlpool of introspection. The idea that it might arise as an emergent property simply from the huge number of neurons is intriguing.
