Dimension-by-Dimension Evidence
What each persona's writings reveal about their stance on each of the six dimensions.
Time
Robert Stalnaker
Standard relativistic physical time.
Space
Robert Stalnaker
Standard relativistic space-time; the possible-worlds machinery operates over abstract structures, not concrete worlds.
Matter
Robert Stalnaker
Substantival; ontology of the actual world is whatever physics says.
Observer
Robert Stalnaker
Embodied epistemic agent; assertions and inquiries make sense in cooperative conversational contexts.
Energy
Robert Stalnaker
Conventional.
Information
Robert Stalnaker
Propositional content is set-theoretic — propositions as sets of possible worlds — and is conserved across logical-conversational manipulation.
Internal Tensions
Where each persona's working synthesis strains against itself.
Coarse-grained propositions (sets of possible worlds) have well-known difficulties accommodating the apparent fine-grained distinctions between necessarily equivalent claims; Stalnaker's pragmatic-presuppositional refinements address some but not all of the cases. The disagreement with Lewis on conditional excluded middle and on the metaphysics of worlds remains open.
