12185 | Logical necessity is epistemic necessity, which is the old notion of a priori [Edgington, by McFetridge] |
Full Idea: Edgington's position is that logical necessity is an epistemic notion: epistemic necessity which, she claims, is the old notion of the a priori. Like Kripke, she thinks this is two-way independent of metaphysical necessity. | |
From: report of Dorothy Edgington (Epistemic and Metaphysical Possibility [1985]) by Ian McFetridge - Logical Necessity: Some Issues §1 | |
A reaction: [her paper was unpublished] She hence thinks an argument can be logically valid, while metaphysically its conclusion may not follow. Dubious, though I think I favour the view that logical necessity is underwritten by metaphysical necessity. |
3447 | All theory is against free will, and all experience is in favour of it [Johnson,S] |
Full Idea: All theory is against free will, and all experience is in favour of it. | |
From: Samuel Johnson (works [1770]), quoted by PG - Db (ideas) |
19399 | Prime matter is nothing when it is at rest [Leibniz] |
Full Idea: Primary matter is nothing if considered at rest. | |
From: Gottfried Leibniz (Aristotle and Descartes on Matter [1671], p.90) | |
A reaction: This goes with Leibniz's Idea 13393, that activity is the hallmark of existence. No one seems to have been able to make good sense of prime matter, and it plays little role in Aristotle's writings. |
