8963 | Four theories of possible worlds: conceptualist, combinatorial, abstract, or concrete [Hoffman/Rosenkrantz] |
Full Idea: There are four models of the ontological status of possible worlds: conceptualist (mental constructions), combinatorial (all combinations of the actual world), abstract worlds (conjunction of propositions), and concrete worlds (collections of concreta). | |
From: J Hoffman/G Rosenkrantz (Platonistic Theories of Universals [2003], 4) | |
A reaction: [the proponents cited are, in order, Rescher, Cresswell, Plantinga and Lewis] They dismiss Rescher and Cresswell, both of whom seem to me more plausible than Plantinga or Lewis. 'Possible' can't figure in the definition. Possible to us, or in reality? |
15530 | A logically determinate name names the same thing in every possible world [Lewis] |
Full Idea: A logically determinate name is one which names the same thing in every possible world. | |
From: David Lewis (How to Define Theoretical Terms [1970], III) | |
A reaction: This appears to be rigid designation, before Kripke introduced the new word. |
