 Transworld Identity or Worldbound Individuals?

Show Summary Details

Chapter 6 is an attempt to show that the Theory of Worldbound Individuals (TWI)—i.e. the theory that any object exists in exactly one possible world—is false, and that there's no good reason to deny that objects exist in more than one world. First, arguments that attempt to show that a denial of TWI entails a contradiction fail, and the so‐called Problem of Transworld Identity is no problem at all. Second, TWI should be rejected because it entails that all of an object's properties are essential to it. The defender of TWI may attempt to defend his view by adopting Counterpart Theory. I conclude by arguing that the Counterpart Theory is both semantically and metaphysically inadequate.
