“The private experience that you perceive forms your world, period. But which world do you inhabit? For if you altered your private sensations of reality, then that world, seemingly the only one, would also change. You do go through transformations of beliefs all the time, and your perception of the world is different. You seem to be, no longer, the person you that you were. You are quite correct — you are not the person that you were, and your world has changed, and not just symbolically.”
