According to rationalism regarding the psychology of moral judgment, people’s moral judgments are generally the result of a process of reasoning that relies on moral principles or rules. By contrast, intuitionist models of moral judgment hold that people generally come to have moral judgments about particular cases on the basis of gut-level, emotion-driven intuition, and do so without reliance on reasoning and hence without reliance on moral principles. In recent years the intuitionist model has been forcefully defended by Jonathan Haidt. One important implication of Haidt’s model is that in giving reasons for their moral judgments people tend to confabulate – the reasons they give in attempting to explain their moral judgments are not really operative in producing those judgments. Moral reason-giving on Haidt’s view is generally a matter of post hoc confabulation. Against Haidt, we argue for a version of rationalism that we call ‘morphological rationalism.’ We label our version ‘morphological’ because according to it, the information contained in moral principles is embodied in the standing structure of a typical individual’s cognitive system, and this morphologically embodied information plays a causal role in the generation of particular moral judgments. The manner in which the principles play this role is via ‘proceduralization’ – such principles operate automatically. In contrast to Haidt’s intuitionism, then, our view does not imply that people’s moral reason-giving practices are matters of confabulation. In defense of our view, we appeal to what we call the ‘nonjarring’ character of the phenomenology of making moral judgments and of giving reasons for those judgments.

Causal compatibilism claims that even though physics is causally closed, and even though mental properties are multiply realizable and are not identical to physical causal properties, mental properties are causal properties nonetheless. This position asserts that there is genuine causation at multiple descriptive/ontological levels; physics-level causal claims are not really incompatible with mentalistic causal claims. I articulate and defend a version of causal compatibilism that incorporates three key contentions. First, causation crucially involves robust patterns of counterfactual dependence among properties.Second, often several distinct such patterns, all subsuming a single phenomenon, exist at different descriptive/ontological levels (e.g., microphysical, neurobiological, macrobiological, and psychological). Third, the concept of causation is governed by an implicit contextual parameter that normally determines a specific descriptive/ontological level as the contextually relevant level, for the context-sensitive semantic evaluation of causal statements.

This chapter formulates and motivates the current favored articulation of the metaphysical doctrine of materialism. It describes an alternative metaphysical position called minimal emergentism, which has two versions; and then contrasts it with stronger kinds of emergentism. Minimal emergentism posits certain inter-level necessitation relations — either nomically necessary connections, or metaphysically necessary connections — that are metaphysically brute. The chapter sets forth what it takes to be some very powerful challenges to materialism — challenges involving features of human consciousness. Finally, the chapter argues that in light of these challenges, minimal emergentism is a viable and theoretically appealing non-materialist metaphysic of mind.

You are given a choice between two envelopes. You are told, reliably, that each envelope has some money in it—some whole number of dollars, say—and that one envelope contains twice as much money as the other. You don’t know which has the higher amount and which has the lower. You choose one, but are given the opportunity to switch to the other. Here is an argument that it is rationally preferable to switch: Let x be the quantity of money in your chosen envelope. Then the quantity in the other is either 1/2x or 2x, and these possibilities are equally likely. So the expected utility of switching is 1/2(1/2x) + 1/2(2x) = 1.25x, whereas that for sticking is only x. So it is rationally preferable to switch. There is clearly something wrong with this argument. For one thing, it is obvious that neither choice is rationally preferable to the other: it’s a tossup. For another, if you switched on the basis of this reasoning, then the same argument could immediately be given for switching back; and so on, indefinitely. For another, there is a parallel argument for the rational preferability of sticking, in terms of the quantity y in the other envelope. But the problem is to provide an adequate account of how the argument goes wrong. This is the two envelope paradox. In an earlier paper Horgan 2000) I offered a diagnosis of the paradox. I argued that the flaw in the argument is considerably more subtle and interesting than is usually believed, and that an adequate diagnosis reveals important morals about both probability and the foundations of decision theory. One moral is that there is a kind of expected utility, not previously noticed as far as I know, that I call nonstandard expected utility. I proposed a general normative principle governing the proper application of nonstandard expected utility in rational decisionmaking. But this principle is inadequate in several respects, some of which I acknowledged in note added in press and some of which I have meanwhile discovered..

In “Generalized Conditionalization and the Sleeping Beauty Problem,” Anna Mahtani and I offer a new argument for thirdism that relies on what we call “generalized conditionalization.” Generalized conditionalization goes beyond conventional conditionalization in two respects: first, by sometimes deploying a space of synchronic, essentially temporal, candidate-possibilities that are not “prior” possibilities; and second, by allowing for the use of preliminary probabilities that arise by first bracketing, and then conditionalizing upon, “old evidence.” In “Beauty and Conditionalization: Reply to Horgan and Mahtani,” Joel Pust replies to the Horgan/mahtani argument, raising several objections. In my view his objections do not undermine the argument, but they do reveal a need to provide several further elaborations of it—elaborations that I think are independently plausible. In this paper I will address his objections, by providing the elaborations that I think they prompt.

The philosophical account of vagueness I call "transvaluationism" makes three fundamental claims. First, vagueness is logically incoherent in a certain way: it essentially involves mutually unsatisfiable requirements that govern vague language, vague thought-content, and putative vague objects and properties. Second, vagueness in language and thought (i.e., semantic vagueness) is a genuine phenomenon despite possessing this form of incoherence—and is viable, legitimate, and indeed indispensable. Third, vagueness as a feature of objects, properties, or relations (i.e., ontological vagueness) is impossible, because of the mutually unsatisfiable conditions that such putative items would have to meet. In this paper I set forth the core claims of transvaluationism in a way that acknowledges and explicitly addresses a challenging critique by Timothy Williamson of my prior attempts to articulate and defend this approach to vagueness. I sketch my favored approach to truth and ontological commitment, and I explain how it accommodates the impossibility of ontological vagueness. I argue that any approach to the logic and semantics of vagueness that both (i) eschews epistemicism and (ii) thoroughly avoids positing any arbitrary sharp boundaries (either first-order or higher-order) will have to be not an alternative to transvaluationism but an implementation of it. I sketch my reasons for repudiating epistemicism. I briefly describe my current thinking about how to accommodate intentional mental properties with vague content within an ontology that eschews ontological vagueness. And I revisit the idea, which played a key role in my earlier articulations of transvaluationism, that moral conflicts provide an illuminating model for understanding vagueness.

Existence monism is defended against priority monism. Schaffer's arguments for priority monism and against pluralism are reviewed, such as the argument from gunk. The whole does not require parts. Ontological vagueness is impossible. If ordinary objects are in the right ontology then they are vague. So ordinary objects are not included in the right ontology; and hence thought and talk about them cannot be accommodated via fully ontological vindication. Partially ontological vindication is not viable. Semantical theorizing outside the ontology room and semantical theorizing in the doorway. Existence monism is theoretically preferable to priority monism.

Moral phenomenology is concerned with the elements of one's moral experiences that are generally available to introspection. Some philosophers argue that one's moral experiences, such as experiencing oneself as being morally obligated to perform some action on some occasion, contain elements that (1) are available to introspection and (2) carry ontological objectivist purportargument from phenomenological introspection.neutrality thesisthe phenomenological data regarding one's moral experiences that is available to introspection is neutral with respect to the issue of whether such experiences carry ontological objectivist purport

A provocative ontological-cum-semantic position asserting that the right ontology is austere in its exclusion of numerous common-sense and scientific posits and that many statements employing such posits are nonetheless true. The authors of Austere Realism describe and defend a provocative ontological-cum-semantic position, asserting that the right ontology is minimal or austere, in that it excludes numerous common-sense posits, and that statements employing such posits are nonetheless true, when truth is understood to be semantic correctness under contextually operative semantic standards. Terence Horgan and Matjaz Potrc argue that austere realism emerges naturally from consideration of the deep problems within the naive common-sense approach to truth and ontology. They offer an account of truth that confronts these deep internal problems and is independently plausible: contextual semantics, which asserts that truth is semantically correct affirmability. Under contextual semantics, much ordinary and scientific thought and discourse is true because its truth is indirect correspondence to the world. After offering further arguments for austere realism and addressing objections to it, Horgan and Potrc consider various alternative austere ontologies. They advance a specific version they call "blobjectivism"--the view that the right ontology includes only one concrete particular, the entire cosmos, which, although it has enormous local spatiotemporal variability, does not have any proper parts. The arguments in Austere Realism are powerfully made and concisely and lucidly set out. The authors' contentions and their methodological approach--products of a decade-long collaboration--will generate lively debate among scholars in metaphysics, ontology, and philosophy.

Alvin Goldman’s contributions to contemporary epistemology are impressive—few epistemologists have provided others so many occasions for reflecting on the fundamental character of their discipline and its concepts. His work has informed the way epistemological questions have changed (and remained consistent) over the last two decades. We (the authors of this paper) can perhaps best suggest our indebtedness by noting that there is probably no paper on epistemology that either of us individually or jointly have produced that does not in its notes and references bear clear testimony to the influence of Professor Goldman’s arguments. The present paper is no exception (and this would be a particularly inapt place to break with our tradition of indebtedness). Professor Goldman has produced a series of discussions that we find particularly important for coming to terms with the venerable idea that there may be truths that can be known a priori (Goldman 1992a, 1992b, 1999). We do not altogether follow his lead, while he draws on the idea that a priori justification has something to do with innateness or processess, we prefer to accentuate the idea that a priori justification turns on a conceptually grounded truths and access via acquired conceptual competence (at least in many significant philosophical cases). Still, in developing our understanding we have been aided by much that Professor Goldman says regarding concepts, conceptual competence, and related psychological processes. The influences should become progressively clear, particularly in the later sections of this paper. What would it take for there to be a priori knowledge or justification? We can begin by reflecting on a widely agreed on answer to this question—one that purports to identify something that would at least be adequate for a priori justification. The answer will then serve as one anchor for the present investigation, a bit of shared ground on which empiricists and rationalists can, and typically do, agree..

I maintain, in defending “thirdism,” that Sleeping Beauty should do Bayesian updating after assigning the “preliminary probability” 1/4 to the statement S: “Today is Tuesday and the coin flip is heads.” (This preliminary probability obtains relative to a specific proper subset I of her available information.) Pust objects that her preliminary probability for S is really zero, because she could not be in an epistemic situation in which S is true. I reply that the impossibility of being in such an epistemic situation is irrelevant, because relative to I, statement S nonetheless has degree of evidential support 1/4.

The paradox of analysis asks how a putative conceptual analysis can be both true and informative. If it is true then isn’t it analytic? And if it is analytic then how can it be informative? Our proposed solution rests on a distinction between explicit knowledge of meaning and implicit knowledge of meaning and on a correlative distinction between two kinds of conceptual competence. If one initially possesses only implicit knowledge of the meaning of a given concept and the associated linguistic expression, then a conceptual analysis can be both analytic and informative.

We sketch the view we call contextual semantics. It asserts that truth is semantically correct affirmability under contextually variable semantic standards, that truth is frequently an indirect form of correspondence between thought/language and the world, and that many Quinean commitments are not genuine ontological commitments. We argue that contextualist semantics fits very naturally with the view that the pertinent semantic standards are particularist rather than being systematizable as exceptionless general principles.
