I show (a) that if spatial relations are, as seems plausible, of such a nature that it makes no sense to say of one thing that it is related to itself, then the Principle is a logical truth, asserting that a certain kind of state of affairs is impossible because the kind of sentence purporting to express it is ill-formed and (b) that even if the Principle were such a truth the problem of individuation would remain. I then examine some of what Leibniz and Wittgenstein have said about the notions of individuation, difference and nonidentity},number = {3},journal = {Philosophy of Science},pages = {260--272},author = {Edwin B.
