10. Modality / C. Sources of Modality / 1. Sources of Necessity

12687	Metaphysical necessities are those depending on the essential nature of things [Ellis]
	Full Idea: A metaphysically necessary proposition is one that is true in virtue of the essential nature of things.
	From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 6)
	A reaction: It take this to be what Kit Fine argues for, though it tracks back to Aristotle. I also take it to be correct, though one might ask whether there are any other metaphysical necessities, ones not depending on essences.
