19440 | How do you know you have conceived a thing deeply enough to assess its possibility? [Vaidya] |
Full Idea: The main issue with learning possibility from conceivability concerns how we can be confident that we have conceived things to the relevant level of depth required for the scenario to actually be a presentation or manifestation of a genuine possibility. | |
From: Anand Vaidya (The Epistemology of Modality [2015], 1.2.2) | |
A reaction: [He cites Van Inwagen 1998 for this idea] The point is that ignorant imagination can conceive of all sorts of absurd things which are seen to be impossible when enough information is available. We can hardly demand a criterion for this. |
16397 | If it might be true, it might be true in particular ways, and possible worlds describe such ways [Stalnaker] |
Full Idea: A clarifying assumption is that if something might be true, then it might be true in some particular way. …Possible worlds begin from this, and the assumption that what might be true can be described as how a possibility might be realised. | |
From: Robert C. Stalnaker (Reference and Necessity [1997], 2) | |
A reaction: This is a leading practitioner giving his best shot at explaining the rationale of the possible worlds approach, addressed to many sceptics. Most sceptics, I think, don't understand the qualifications the practitioners apply to their game. |
16399 | Possible worlds are ontologically neutral, but a commitment to possibilities remains [Stalnaker] |
Full Idea: I argue for the metaphysical neutrality of the possible worlds framework, but I do not suggest that its use is free of ontological commitment to possibilities (ways things might be, counterfactual situations, possible states of worlds). | |
From: Robert C. Stalnaker (Reference and Necessity [1997], 2) | |
A reaction: Glad to hear this, as I have always been puzzled at possible aspirations to eliminate modality (such as possibility) by introducing 'possible' worlds. Commitment to possibilities I take to be basic and unavoidable. |
16398 | Possible worlds allow discussion of modality without controversial modal auxiliaries [Stalnaker] |
Full Idea: The main benefit of the possible worlds move is to permit one to paraphrase modal claims in an extensional language that has quantifiers, but no modal auxiliaries, so the semantic stucture of modal discourse can be discussed without the controversies. | |
From: Robert C. Stalnaker (Reference and Necessity [1997], 2) | |
A reaction: The strategy introduces the controversy of possible worlds instead, but since they just boil down to collections of objects with properties, classical logic can reign. Possible worlds are one strategy alongside many others. |
16396 | Kripke's possible worlds are methodological, not metaphysical [Stalnaker] |
Full Idea: The possible worlds framework that Kripke introduces should be understood not as a metaphysical theory, but as a methodological framework. | |
From: Robert C. Stalnaker (Reference and Necessity [1997], Intro) | |
A reaction: That's certainly how I see possible worlds. I lose no sleep over whether they exist. I just take a set of possible worlds to be like cells in a spreadsheet, or records in a database. |
16408 | Rigid designation seems to presuppose that differing worlds contain the same individuals [Stalnaker] |
Full Idea: A rigid designator is a designator that denotes the same individual in all possible worlds; doesn't this presuppose that the same individuals can be found in differing possible worlds? | |
From: Robert C. Stalnaker (Reference and Necessity [1997], 5) | |
A reaction: This is part of Stalnaker's claim that Kripke already has a metaphysics in place when he starts on his semantics and his theory of reference. Kripke needs a global domain, not a variable domain. Possibilities suggest variable domains to me. |
