Mixed Selectivity and Network-Level Meaning

Philip Ball is a former Nature editor of 20 years and the author of over 30 books spanning quantum physics, consciousness, and the strange frontiers of biology. In How Life Works, he argues that everything we’ve been taught about life — genes, blueprints, biological machines — is deeply incomplete.

Get How Life Works: https://amzn.to/46dQRMlBiology isn’t built from instructions. It’s built from self-organising systems that sense, evaluate, predict and act. Cognition didn’t start with brains. Purpose isn’t mystical. And causation may not live where we think it does.

Expect to learn why genes aren’t in control, how cells make decisions without neurons, what combinatorial explosion means for biology, why self-organisation shapes development, how agency emerges from physics, and what all of this means for consciousness — and much more…
