Stan Persky’s book review of Barry Dainton’s Self: Philosophy in Transit is an extended, entertaining, and instructive grand tour of many ideas about the self, that remarkable ability humans have “to sleepily glance at the bathroom mirror in the morning, and not only recognize ourselves, but also reflectively note, ‘Hmm, I don’t like myself very much these days. I wonder what I can do to change who and/or what I am.’” Thought experiments like the “ultimate simulation simulation machine” and “teleportation” make an appearance along the way.
