  1. (metaphysics) A proponent of ersatzism, the doctrine that possible worlds are merely abstract and do not have the same reality as the present world
    • 1986, David K. Lewis, On the Plurality of Worlds, edition 2001 Routledge ed., page 140:
      The ersatzers just do not believe in what I call worlds; and sometimes -- depending on which version of ersatzism we encounter -- I just do not believe in what they call worlds.

      My quarrel with the Ersatzer is perhaps not very deep, and I should not be too distressed if I were forced back to his position. But the quarrel is real. Mere representations of possibilities, which is what the Ersatzer uses, are not to be identified with the possibilities that we seek to represent.

      Now that the metaphysics and semantics have been given for ersatzer presentism, I should answer one possible objection: why is it that a certain atomic proposition p appears in a given E-related time if not because it was the case that p? But if this is the explanation, if this is how the story ultimately bottoms out, then how is ersatzer presentism any better off than Priorian presentism.
