The Blind Painter. Have you seen this video? It is an example of how a systems view can help us understand how perception works. He was born with no eyes, yet paints landscapes and buildings with great skill.
He is demonstrating the feedback loop of perception. The senses input information from the environment, the perception apparatus, which includes the whole body in it’s scope, produces an internal model of the environment, that the hands use to paint. Remove eyes from the loop and it continues with what is available. The system demands that the perception loop be functional in all mobile species.
Even single celled creatures have a rudimentary perception loop going on. Like the lactose intolerant e. coli or stem cells reacting to their environment to form bone and muscle(Bruce Lipton). The intelligence is in the system.
