On the Foundations of Chalmers’ Modal Monism

22 April 2024  |  15:00  |  Maria Zambrano Seminar


David Chalmers’ famous two-dimensional argument against materialism presupposes “Modal Monism,” i.e., that in analyzing both metaphysical necessity and apriority, we can do with a single space of possible worlds. Chalmers suggests that a sentence S can be true at a single world W in two different ways: W considered as actual (“W verifies S”) and W considered as counterfactual (“W satisfies S”). He contends that this framework provides a unified analysis of the necessary a posteriori (and the contingent a priori). In the talk, I continue my critical examination of Chalmers’ framework. I raise some new worries concerning it.
