Single Idea 15398

[filed under theme 8. Modes of Existence / B. Properties / 4. Intrinsic Properties ]

Full Idea

If a globally intrinsic properties are those that never vary between duplicates across possible worlds, then necessarily coextensive properties will either be both intrinsic or both extrinsic.

Gist of Idea

Global intrinsic may make necessarily coextensive properties both intrinsic or both extrinsic

Source

comment on David Lewis (On the Plurality of Worlds [1986], p.61-2) by Ross P. Cameron - Intrinsic and Extrinsic Properties 'Analysis'

Book Ref

'Routledge Companion to Metaphysics', ed/tr. Le Poidevin/Simons etc [Routledge 2012], p.268

A Reaction

Presumably this problem would arise if some intrinsic property entailed an extrinsic property (or, less likely, vice versa). These sorts of problems arise when you try to define everything extensionally (even across possible worlds).
