    Reasons For

    1 perspective
    Reason for
    ?
    • 1.The central justification for possibilism is that it provides truthmakers for modal propositions by grounding them in the modal properties of individuals.
      ?

      Think about whether this reason is strong or weak

    • 2.If the purported truthmakers for modal propositions could fail altogether to exist, then for all we know there may in fact be no such truthmakers.
      ?

      Think about whether this reason is strong or weak

    • 3.If there are no truthmakers for modal propositions, possibilism's central philosophical justification collapses.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Possibilism can ground modal truth in abstract possible worlds as primitive entities rather than in the modal properties of concrete individuals.
      ?

      Think about whether this reason is strong or weak

    • 2.If possible worlds themselves are necessary existents (as Lewis and Plantinga both hold for their respective frameworks), possibilism inherits necessitarian truthmakers without requiring necessitism about individuals.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore possibilism's justificatory structure does not depend on the necessary existence of possibilia, severing the claimed essential connection.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Williamson's own necessitism entails that merely possible individuals exist as necessary but propertyless abstracts, which are ontologically discontinuous from the robust possibilia possibilists invoke.
      ?

      Think about whether this reason is strong or weak

    • 2.A possibilism grounded in contingently existing but modally rich possibilia is coherent if one accepts a deflationary truthmaker theory where modal truths require only their truth conditions, not existing grounds.
      ?

      Think about whether this reason is strong or weak

    • 3.The claim that necessitism is essential to possibilism conflates Williamson's specific theoretical package with possibilism as a general modal-ontological commitment.

    Although it is a logical truth of SQML, necessitism is not analytically entailed by possibilism. There is, in particular, nothing in the idea of a mere possibile that demands its necessity, nothing that rules out worlds from which it might be altogether absent, worlds (in addition to those in which it is either concrete or non-concrete) in which nothing is identical to it. This might lead one to wonder whether SQML, by building necessitism into its logical foundations, has (from a possibilist pe
