3Dism and 4Dism
Aha - something I've suspected for a while but been rebuked for thinking has been defended in print by someone else. In a recent paper in Erkenntnis (the link requires a subscription), Kristie Miller argues that three-dimensionalist and four-dimensionalist views about persistance are intertranslatable, equally simple, and equally explanatory. Though I'm not sure I'd go so far as to say they're 'metaphysically equivalent' as she does (I guess I hear that as conveying a bit more than she intends by it, as captured by her four clauses on p. 92), I have often wondered whether the two theories are really just two ways of describing the same underlying facts, and if so how much really hangs on which of them we choose.
