Abstract

There is something undeniably puzzling, difficult, about relations. Socrates is a fine individual substance, and his paleness a fine accident; but what of his being taller than Simmias? If to our eyes Aristotle is working no harder in chapter seven of the Categories than in chapter eight, to medieval eyes things were messier there—or at any rate sufficiently unsettled to yield an extended and hotly disputed controversy than which only the question of universals is knottier. Leibniz evidently managed no better than Aristotle, which scarcely counts against him: there were of course more medieval thinkers offering their glosses on Aristotle on relations than there are Leibniz scholars, but those of the latter who’ve thought they had something helpful to say about Leibniz on relations would agree that things are unsettled, and maybe even hotly disputed. Readers can gain some sense of this from Dennis Plaisted’s excellent but sadly under-reviewed contribution to the debate in Leibniz on Purely Extrinsic Denominations, which represents the most extended and detailed attack on broadly “reductionist” readings of Leibniz on relations to date. For reasons owing more to divine intervention than creaturely freedom, the present review is delinquent in a way that discussion of Plaisted’s work should not be.
