10. Modality / A. Necessity / 5. Metaphysical Necessity

3105	Is 'Hesperus = Phosphorus' metaphysically necessary, but not logically or epistemologically necessary? [Segal]
	Full Idea: It is metaphysically necessary that Hesperus is Phosphorus, but not logically necessary, since logical deduction could not reveal its truth, and it is not epistemologically necessary, as the ancient Greeks didn't know the identity. (Natural necessity?)
	From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 1.6)
