 Chalmers has entered into these interpretive questions in considerable detail over many publications. The starting point for his approach is outlined in (Chalmers and Jackson 2001), where he suggests that scenarios can be understood as PQTI sentences: where P states microphysical truths, Q states phenomenal truths, T is a ‘that’s all’ clause indicating that P and Q provide a complete description of a possible universe, and I indicates the subject’s notional location within that universe. P and Q employ a canonical vocabulary that fully specifies the essential nature of the fundamental properties upon which all other properties in a possible world supervene. Thus, PQTI sentences provide an epistemically transparent access to the space of epistemic and metaphysical possibility (simply removing the self-locating information from a PQTI sentence yields a complete description of a corresponding possible world, PQT). The 1-intensions of one’s ordinary language expressions are then determined by the individual subject’s ideally reflective dispositions to judge sentences true, assuming the truth of different PQTI-sentences. And 2-intensions are fixed by one’s reasoning about PQT sentences considered as counterfactual (given assumptions about PQTI). (Chalmers 2006, 2011b) further articulates how the space of epistemic possibility can be understood, how scenarios are related to possible worlds, and how 1- and 2-intensions are assigned to token representations.
