10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / b. Conceivable but impossible

10652	Conceivability may indicate possibility, but literary fantasy does not [Varzi]
	Full Idea: Conceivability may well be a guide to possibility, but literary fantasy is by itself no evidence of conceivability.
	From: Achille Varzi (Mereology [2003], 2.1)
	A reaction: Very nice. People who cite 'conceivability' in this context often have a disgracefully loose usage for the word. Really, really conceivable is probably our only guide to possibility.

10. Modality / E. Possible worlds / 3. Transworld Objects / b. Rigid designation

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.
