Question from a student: “I’m scared of metaphysics. A friend of mine wrote an essay for another course, in which he denied the persistence of personal identity. According to my friend, since some things about me have changed during the last two years, the me of today isn’t the same as the me of two years ago. We are literally different persons. This is deeply disturbing."
Reply: "... if my personal identity has no persistence, then how could ‘I’ find it disturbing? The problem with your friend’s argument isn’t metaphysical reasoning, but flawed metaphysical reasoning... there must be a real you that persists through the changes. If that weren’t true, then it wouldn’t even make sense for you to say “I have changed” -- because at the moment of the change, “I” would have ceased to exist.... Metaphysics is just thinking carefully about what the real world is like.... Trust me. You exist.”
