18829 | The truth grounds for 'not A' are the possibilities incompatible with truth grounds for A [Rumfitt] |
Full Idea: The truth-grounds of '¬A' are precisely those possibilities that are incompatible with any truth-ground of A. | |
From: Ian Rumfitt (The Boundary Stones of Thought [2015], 7.1) | |
A reaction: This is Rumfitt's proposal for the semantics of 'not', based on the central idea of a possibility, rather than a possible world. The incompatibility tracks back to an absence of shared grounding. |
