Even more mysterious—and perhaps not unrelated—is our ability to “reflect” on ourselves as the first introspective primates. This ability displays itself in ways as different as the mythical Narcissus looking at his reflection in a lake to Internet pioneer Jaron Lanier's invention of virtual reality to transport you outside your own body.
