Why am I me? and why is my world so classical?
  This is an attempt to apply Nagel's distinction between internal and external statements to the interpretation of quantum mechanics. I propose that this distinction resolves the contradiction between unitary evolution and the projection postulate. I also propose a more empirically realistic version of the projection postulate. The result is a version of Everett's relative-state interpretation, including a proposal for how probabilities are to be understood.   Based on a talk given at the 9th UK Foundations of Physics meeting in Birmingham on 12 September 2000.
