I am a strange loop

Deep down, a human brain is made of particles; on a higher level, neurons; on a yet higher level, abstractions called "symbols." The central symbol is the one we call "I," which seems utterly real. But is it real, or merely a convenient fiction? Does it control the particles in our brain, or is it manipulated by the laws of physics? The author of Godel, Escher, Bach finds the key to the mystery in the "strange loop," an abstract feedback loop inhabiting our brains.
