Author’s Abstract1

  1. Chapters 5 to 7 concern the metaphysics of modality2, that is, metaphysical issues to do with possibility and necessity.
  2. In Chapter 5, after considering some analogies between time and modality3, I look at a well-known attempt to prove that true identity statements are necessarily true and raise some possible objections to this alleged proof. I also examine some of its supposed metaphysical implications, in particular its bearing upon the mind-body problem.
