We're used to thinking about the self as an independent entity, something that we either have or are. In The Ego Tunnel, philosopher Thomas Metzinger claims otherwise: No such thing as a self exists. The conscious self is the content of a model created by our brain - an internal image, but one we cannot experience as an image. Everything we experience is "a virtual self in a virtual reality." But if the self is not "real," why and how did it evolve? How does the brain construct it?
