The human brain is only meat. The enigma has always been how a mere hunk of matter can be conscious, and can reason, create, fantasize and feel. At least one of the crucial answers is that, in a chaotic, uncertain world in constant flux, the brain learned to predict. Prediction fuels a variety of mental states, including perceiving and imagining, and the intentions that lead to our actions are expressions of these mechanisms. A complicated web of neurological connections at a variety of levels generates these predictions – probabilistic assessments of the immediate future. The “predictive processing (PP)” theory offers an intriguing perspective on the way the human brain interacts with the world.
