Ordinal polytheism is motivated by the cosmological and design arguments. It is also motivated by Leibnizian–Lewisian modal realism. Just as there are many universes, so there are many gods. Gods are necessary concrete grounds of universes. The god-universe relation is one-to-one. Ordinal polytheism argues for a hierarchy of ranks of ever more perfect gods, one rank for every ordinal number. Since there are no maximally perfect gods, ordinal polytheism avoids many of the familiar problems of monotheism. It links theology with (...) counterpart theory, mathematics and computer science. And it entails that the system of universes has an attractive axiological structure. (shrink)

In his influential “Naming and Necessity,” Saul Kripke has deployed a new sort of analytical apparatus in support of the classical Cartesian argument that minds and bodies must be distinct because they can be imagined separately. In the initial section of this paper, I shall first paraphrase Kripke's version of that argument, and then suggest a way in which even one who accepts all of its philosophical presuppositions may avoid its conclusion. In the second section, I shall defend this suggestion (...) against some of the possible objections to it.Recent materialists have not been overly impressed by the Cartesian claim that minds and bodies can be imagined or conceived separately from each other. Their usual reply is that this is only to be expected, given the contingent nature of the identify involved. Kripke, however, has argued persuasively that such a reply is unacceptable because it overlooks a crucial fact about the terms in which the identity theory is couched. (shrink)

In “Naming and Necessity” Saul Kripke describes some cases which, he claims, provide counterexamples both to cluster theories and, more generally, to description theories of proper names. My view of these cases is that while they do not provide counterexamples to cluster theories, they can be used to provide evidence against single-description theories. In this paper I shall defend both of the claims involved in my view.
