Single Idea 18383

[catalogued under 10. Modality / E. Possible worlds / 1. Possible Worlds / d. Possible worlds actualism]

Full Idea

Plantinga rejects other possible worlds, but adds to our world an uncountable multitude of sets of propositions, each set a way that the world might have been, but is in fact not. (Roughly, for each Lewis world, Plantinga has such a set).

Gist of Idea

Plantinga says there is just this world, with possibilities expressed in propositions

A Reaction

To me it seems as ontologically extravagant to postulate unexpressed propositions as to postulate concrete possible worlds. I think the best line is that there is just the actual world, with the possibilities implied in its dispositions.
