 Relatedly, supervenience can also be used to capture the traditional distinction between internal and external relations. As Lewis has noted (1986b, 62), an internal relation (such as being taller than) supervenes on the intrinsic natures of its relata. An extrinsic relation (such as being 3 kilometers from ) does not. The main difference between this case and those above is that here there is no real dispute about whether the supervenience thesis holds or not; it is widely agreed that there are two kinds of relations.
