Because I could have not married her (failed to take the English honors class where we met, e.g.) and still have been *myself*. Consider Kripke's table T, which is brown and made of wood. We can have a possible world in which T is black because someone painted it. But can we have a world in which T itself, that very table, was made of another material? There might be some other table, T', which served a corresponding function (sitting in my dining room, for example), that was made of plastic. But that would not mean that T' = T. Whereas T is T whether painted black or not. Thus Kripke and me. -- John Cowan cowan@ccil.org One art/there is/no less/no more/All things/to do/with sparks/galore --Douglas Hofstadter
