Single Idea 19258

[filed under theme 10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / a. Conceivable as possible ]

Full Idea

For Chalmers, that water is XYZ is 'primary possible' (a priori, or conceptually), because it is true in some world considered as actual. It is 'secondary impossible', when it is evaluated from the Earth as actual.

Gist of Idea

Evaluate primary possibility from some world, and secondary possibility from this world

A Reaction

[compressed] This is Chalmers' account of how we can know possibility from conceivability, via his two-dimensional semantics (see alphabetical themes).


The 26 ideas with the same theme [ if conceivable then it is possible]:

Scholastics assess possibility by what has actually happened in reality [Suárez, by Boulter]
People who are ignorant of true causes imagine anything can change into anything else [Spinoza]
Error does not result from imagining, but from lacking the evidence of impossibility [Spinoza]
What is thinkable is possible [Wittgenstein]
Conceivability is no proof of possibility [Putnam]
Imagination tests what is possible for all we know, not true possibility [Ellis]
Empirical evidence shows that imagining a phenomenon can show it is possible [Shoemaker]
Imagination reveals conceptual possibility, where descriptions avoid contradiction or incoherence [Shoemaker]
'Conceivable' is either not-provably-false, or compatible with what we know? [Shoemaker]
Kripke's essentialist necessary a posteriori opened the gap between conceivable and really possible [Soames on Kripke]
Kripke gets to the necessary a posteriori by only allowing conceivability when combined with actuality [Kripke, by Soames]
We can imagine being beetles or alligators, so it is possible we might have such bodies [Plantinga]
It is hard or impossible to think of Caesar as not human [Wiggins]
Modal Rationalism: conceivability gives a priori access to modal truths [Chalmers, by Stalnaker]
Evaluate primary possibility from some world, and secondary possibility from this world [Chalmers, by Vaidya]
Maybe logical possibility does imply conceivability - by an ideal mind [Chalmers]
Williamson can't base metaphysical necessity on the psychology of causal counterfactuals [Lowe on Williamson]
We scorn imagination as a test of possibility, forgetting its role in counterfactuals [Williamson]
A proposition is 'correctly' conceivable if an ominiscient being could conceive it [Rosen]
Empiricism explores necessities and concept-limits by imagining negations of truths [Sidelle]
Contradictoriness limits what is possible and what is imaginable [Sidelle]
Empiricist saw imaginability and possibility as close, but now they seem remote [Bird]
Only ideal conceivability could indicate what is possible [Schaffer,J]
If conceivability is a priori coherence, that implies possibility [Tahko]
How do you know you have conceived a thing deeply enough to assess its possibility? [Vaidya]
Define conceivable; how reliable is it; does inconceivability help; and what type of possibility results? [Vaidya]
