    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Materialism, as a thesis about the actual world, entails no commitments about the ontological status of non-actual possible worlds.
      ?

      Think about whether this reason is strong or weak

    • 2.Modal realism (Lewis) and materialism are logically independent doctrines: one can be a materialist nominalist who rejects possible worlds entirely.
      ?

      Think about whether this reason is strong or weak

    • 3.Quine's extensionalist materialism explicitly denied possible worlds as ontologically profligate, showing materialism can undercut rather than support modal realism.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.The modal entailment account presupposes possible worlds semantics, making the argument circular: worlds are used to validate materialism which then validates worlds.
      ?

      Think about whether this reason is strong or weak

    • 2.Chalmers' conceivability arguments demonstrate that materialist modal entailment fails precisely where phenomenal consciousness is concerned, undermining the modal bridge.
      ?

      Think about whether this reason is strong or weak
