St. Francis of Assisi talked to flowers and rocks. The idea that mind was a property of all matter -- panpsychism -- was commonplace back then. Modern philosophers view mind is an emergent property, a very special something-out-of-nothing that mysteriously emerges from matter that seemingly doesn’t have mind as a property. Emergent systems are everywhere, so I can buy the idea that mind is an emergent property, but part of me wonders if man can confidently predict the limits on where and how mind might emerge in a universe that is billions of years old. Yo, listen up rock. I’m talking here.
