Abstract

One of the most certain truths in the world is Descartes' "I think, therefore I am". Descartes was so certain of the existence of some kind of essential _self_ that others have coined the term "Cartesian theater" to describe the sense that we all have of being the audience enjoying the rich play of our experiences. We tend to believe in an enduring self, independent of our individual percepts. Sometimes this virtual "self" in our mind, sitting in the audience of the Cartesian theater who watches our thoughts is referred to as a homunculus. This is not necessarily to imply that most of us believe that the self or homunculus is an identifiable region of the brain like the pineal gland, just that at some level of organization, we assume that there is a self that is separate from the stuff that self experiences, remembers, thinks about, etc.
