Rather than as a set of absolute physical principles, reality is best understood as a set of phenomena our brain constructs to guide our behavior. To put it simply: we actively create everything we see, and there is no aspect of reality that does not depend on consciousness.
His research interests include Vision, Cognitive Science, Consciousness, and Evolutionary Models of Perception.
