10. Modality / D. Knowledge of Modality / 1. A Priori Necessary

12553	Some of our ideas contain relations which we cannot conceive to be absent [Locke]
	Full Idea: In some of our ideas there are certain relations, habitudes, and connexions, so visibly included in the nature of the ideas themselves, that we cannot conceive them separable from them, by any power whatsoever.
	From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.03.29)
	A reaction: This is the conceptual version of a priori necessity. The question then becomes whether this necessity can be traced back to reality, or merely to conventions which created the ideas in the first place. Analytic philosophy likes this idea.

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.
