Replying to me here, Graham Harman explains his objections to relational ontologies, arguing that they fail to make a distinction between the “two sorts of relations” in which an entity is involved. These are not “the famous ‘internal’ and ‘external’ relations,” but are what he “somewhat whimsically” calles the “domestic” and “foreign” relations of an object. (I like this distinction, though I’m not sure how it’s different from internal and external relations.)
GH: “Surely Adrian doesn’t want to claim that the cane toad is a set of all its relations? If Mars were five inches further along in its course than it currently is, would the cane toad be a different cane toad than it is now?” [. . .]
