Here I defend the position that some singular terms for properties are rigid designators, responding to Stephen P. Schwartz’s interesting criticisms of that position. First, I argue that my position does not depend on ontological parsimony with respect to properties – e.g., there is no need to claim that there are only natural properties – to get around the problem of “unusual properties.” Second, I argue that my position does not confuse sameness of meaning across possible worlds with sameness of designation, or rigid designation. Third, I argue that my position does not founder by way of failing to assign rigidity the work of grounding a posteriori necessity.

More than a century ago, G. E. Moore famously offered an extended inference to reject what are in effect two substantially different types of ethical naturalism. Although some naturalistic doctrines targeted by that inference make semantic claims that, if true, would entail certain metaphysical claims, it is also possible that those semantic doctrines could be false and the metaphysical ones true at the same time. For if semantic naturalism is true, then moral terms and sentences are reducible, by an analysis of what they mean, into some purely descriptive terms and sentences. But, if metaphysical naturalism is true, then the moral properties and propositions expressed by moral terms and sentences are reducible to purely natural properties and propositions. By conflating claims about meaning with claims about reference, Moore‟s original inference proved vulnerable to a number of well known objections. But we believe there is a revised Moorean inference that can succeed, and we offer that argument here. Its scope is restricted to semantic reductivist forms of ethical naturalism: those that rest on theses claiming the reducibility of expressions in the moral vocabulary to expressions in a non-moral one. A not uncommon philosophical view in Moore‟s day, such theses remain live options in metaethics (as we‟ll presently show). Although our inference is run for some putative equivalences between moral and purely descriptive terms, it could easily be adapted against ethical naturalist theses 1 involving moral concepts and thoughts as well as sentences. Like Moore, we take the successful inference to consist in an open question argument („OQA’) followed by the naturalistic-fallacy charge („NFC‟). But, unlike Moore, we identify semantic naturalism as the only naturalistic doctrine vulnerable to the inference, and we offer adequate support for the inference‟s premises. Naturalism in ethics is thus undermined, though not refuted in all its forms: semantical naturalism comes out false, but metaphysical naturalism might still be true..

It is generally assumed that rigidity plays a key role in explaining the necessary a posteriori status of identity statements, both between proper names and between natural kind terms. However, while the notion of rigid designation is well defined for singular terms, there is no generally accepted definition of what it is for a general term to be rigid. In this paper I argue that the most common view, according to which rigid general terms are the ones which designate the same kind in all possible worlds, fails to deliver a posteriori necessities. I also present an alternative view, on which the work of explaining a posteriori necessities is not done by rigidity, but by a related metasemantic notion, which I call actuality - dependence.

What are the conditions on a successful naturalistic account of moral properties? In this paper I discuss one such condition: the possibility of moral concepts playing a role in good empirical theories on a par with those of the natural and social sciences. I argue that Peter Railton’s influential account of moral rightness fails to meet this condition, and thus is only viable in the hands of a naturalist who doesn’t insist on it. This conclusion generalises to all versions of naturalism that give a significant role to a dispositional characterisation of moral properties. I also argue, however, that the epistemological and semantic motivations behind naturalism are consistent with a version of naturalism that doesn’t insist on the explanatory condition. The conclusion is that those naturalists who are attracted to accounts of moral properties such as Railton’s would do better not to insist on this\break condition.

In the first post World War II identity theories (e.g., Place 1956, Smart 1962), mind brain identities were held to be contingent. However, in work beginning in the late 1960's, Saul Kripke (1971, 1980) convinced the philosophical community that true identity statements involving names and natural kind terms are necessarily true and furthermore, that many such necessary identities can only be known a posteriori. Kripke also offered an explanation of the a posteriori nature of ordinary theoretical identities such as that water = H2O. We identify the kinds and substances involved in theoretical identities by certain of their contingent properties. What we discover when we discover a theoretical identity is the underlying nature of the kind that we identify by those contingent properties. Now, of course, it was being a posteriori, not being contingent, that mattered to the identity theorists anyway, so the necessity of identity is not, in itself, damaging to mind brain identity theories. However, Kripke also argued persuasively that the alleged mind brain identities could not be treated in the same way as ordinary theoretical identities. We "identify" pain by feeling it, and surely how it feels is an essential property of pain, not a contingent property. Thus, a mind body identity theory must provide a different explanation of why its identities are a posteriori. A new wave of materialists has appeared on the scene with a new strategy for explaining [1] the a posteriori nature of its alleged identities. The strategy is to locate the explanation for the a posteriori nature of mind body identities, not on the side of the world, but on the side of the mind -in different ways of thinking about or imagining, or in different concepts. Thus, on this new view, there is only one property—this brain process type, which is identical with this pain..

Take naturalism to be the idea that there is no such person as God or anything like God. Many philosophers hold that naturalism can accommodate serious moral realism. Many philosophers (and many of the same philosophers) also believe that moral properties supervene on non-moral properties, and even on naturalistic properties (where a naturalistic property is one such that its exemplification is compatible with naturalism). I agree that they do thus supervene, and argue that this makes trouble for anyone hoping to argue that naturalism can accommodate morality.

While "moral naturalism" is sometimes used to refer to any approach to metaethics intended to cohere with naturalism in metaphysics more generally, the label is more usually reserved for naturalistic forms of moral realism according to which there are objective moral facts and properties and these moral facts and properties are natural facts and properties. Views of this kind appeal to many as combining the advantages of naturalism and realism but have seemed to many others to do inadequate justice to central dimensions of our practice with our moral concepts. This entry examines some of these concerns and some ways in which moral naturalists have responded to them. It also profiles central aspects of the more particular views of some leading contemporary advocates of moral naturalism.

More than a century ago, G. E. Moore famously attempted to refute all versions of moral naturalism by offering the open question argument (OQA) followed by the “naturalistic fallacy” charge (NF).1 Although there is consensus that this extended inference fails to undermine all varieties of moral naturalism, OQA is often vindicated as an argument against analytical moral naturalism. By contrast, NF usually finds no takers at all. ln this paper we argue that analytical naturalism of the sort recently proposed by Frank Jackson and Michael Smith does after all rest on a mistake — though perhaps not the NF. Analytical moral naturalism is roughly the doctrine that some moral predicates and sentences are a priori equivalent to predicates and sentences framed in non-moral terms (Jackson 2003: 558). Given moral naturalism, it is at least possible that there are some such a priori or conceptual equivalences. But a properly construed OQA challenges this reductive strategy by showing that it is open to doubt on a priori grounds. We further contend that, in the dialectical context created by our OQA, a "digging in the heeis" defense of the strategy would beg the question. ll..

The “scientific essentialist” doctrine asserts that the following are examples of a posteriori necessary identities: water is H2O; gold is the element with atomic number 79; and heat is the motion of molecules. Evidence in support of this assertion, however, is difficult to find. Both Hilary Putnam and Saul Kripke have argued convincingly for the existence of a posteriori necessities. Furthermore, Kripke has argued for the existence of a posteriori necessary identities in regard to a particular class of statements involving proper names. Neither Kripke nor Putnam, however, has argued convincingly that sentences containing syntactically complex terms or descriptive phrases can express a posteriori necessary identities. I will argue by way of a hypothetical example that ‘water is H2O’ does not express a necessary identity. My argument is unique in that it attacks the relevant sufficiency claim needed to underwrite this putative necessary identity.1 That is, even if we grant that water is necessarily composed of H2O, we should not accept that H2O necessarily forms water.
