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.

Morphological content is information that is implicitly embodied in the standing structure of a cognitive system and is automatically accommodated during cognitive processing without first becoming explicit in consciousness. We maintain that much belief-formation in human cognition is essentially morphological : i.e., it draws heavily on large amounts of morphological content, and must do so in order to tractably accommodate the holistic evidential relevance of background information possessed by the cognitive agent. We also advocate a form of experiential evidentialism concerning epistemic justification—roughly, the view that the justification-status of an agent’s beliefs is fully determined by the character of the agent’s conscious experience. We have previously defended both the thesis that much belief-formation is essentially morphological, and also a version of evidentialism. Here we explain how experiential evidentialism can be smoothly and plausibly combined with the thesis that much of the cognitive processing that generates justified beliefs is essentially morphological. The leading idea is this: even though epistemically relevant morphological content does not become explicit in consciousness during the process of belief-generation, nevertheless such content does affect the overall character of conscious experience in an epistemically significant way: it is implicit in conscious experience, and is implicitly appreciated by the experiencing agent.

The semantic blindness objection to contextualism challenges the view that there is no incompatibility between (i) denials of external-world knowledge in contexts where radical-deception scenarios are salient, and (ii) affirmations of external-world knowledge in contexts where such scenarios are not salient. Contextualism allegedly attributes a gross and implausible form of semantic incompetence in the use of the concept of knowledge to people who are otherwise quite competent in its use; this blindness supposedly consists in wrongly judging that there is genuine conflict between claims of type (i) and type (ii). We distinguish two broad versions of contextualism: relativistic-content contextualism and categorical-content contextualism. We argue that although the semantic blindness objection evidently is applicable to the former, it does not apply to the latter. We describe a subtle form of conflict between claims of types (i) and (ii), which we call différance-based affirmatory conflict. We argue that people confronted with radical-deception scenarios are prone to experience a form of semantic myopia (as we call it): a failure to distinguish between différance-based affirmatory conflict and outright inconsistency. Attributing such semantic myopia to people who are otherwise competent with the concept of knowledge explains the bafflement about knowledge-claims that so often arises when radical-deception scenarios are made salient. Such myopia is not some crude form of semantic blindness at all; rather, it is an understandable mistake grounded in semantic competence itself: what we call a competence-based performance error

Within cognitive science, mental processing is often construed as computation over mental representations—i.e., as the manipulation and transformation of mental representations in accordance with rules of the kind expressible in the form of a computer program. This foundational approach has encountered a long-standing, persistently recalcitrant, problem often called the frame problem; it is sometimes called the relevance problem. In this paper we describe the frame problem and certain of its apparent morals concerning human cognition, and we argue that these morals have significant import regarding both the nature of moral normativity and the human capacity for mastering moral normativity. The morals of the frame problem bode well, we argue, for the claim that moral normativity is not fully systematizable by exceptionless general principles, and for the correlative claim that such systematizability is not required in order for humans to master moral normativity.

What is real? Less than you might think. We advocate austere metaphysical realism---a form of metaphysical realism claiming that a correct ontological theory will repudiate numerous putative entities and properties that are posited in everyday thought and discourse, and also will even repudiate numerous putative objects and properties that are posited by well confirmed scientific theories. We have lately defended a specific version of austere metaphysical realism which asserts that there is really only one concrete particular, viz., the entire cosmos (see Horgan and Potr (2000, 2002), Potr (2003)). But there are various potential versions of the generic position we are here calling austere metaphysical realism; and it is the generic view that constitutes the ontological part of the overall approach to realism and truth that we will describe here. What is true? More than you might think, given our austere metaphysical realism. We maintain that truth is semantically correct affirmability, under contextually operative semantic standards. We also maintain that most of the time, the contextually operative semantic standards work in such a way that semantic correctness (i.e., truth) is a matter of indirect correspondence rather than direct correspondence between thought or language on the one hand, and the world on the other.1 When correspondence is indirect rather than direct, a given statement (or thought) can be true even if the correct ontology does not include items answering to all the referential commitments (as we will here call them) of the statement. 2 This means that even if a putative object is repudiated by a correct ontological theory, ordinary statements that are putatively about that object may still be true. For instance, the statement “The University of St. Andrews is in Scotland” can be semantically correct (i.e., true) even if the right ontology does not include any entity answering to the referring term ‘The University of St. Andrews’, or any entity...

Metaethics, understood as a distinct branch of ethics, is often traced to G. E. Moore's 1903 classic, Principia Ethica. Whereas normative ethics is concerned to answer first order moral questions about what is good and bad, right and wrong, metaethics is concerned to answer second order non-moral questions about the semantics, metaphysics, and epistemology of moral thought and discourse. Moore has continued to exert a powerful influence, and the sixteen essays here (most of them specially written for the volume) represent the most up-to-date work in metaethics after, and in some cases directly inspired by, the work of Moore.

We propose an approach to epistemic justification that incorporates elements of both reliabilism and evidentialism, while also transforming these elements in significant ways. After briefly describing and motivating the non-standard version of reliabilism that Henderson and Horgan call “transglobal” reliabilism, we harness some of Henderson and Horgan’s conceptual machinery to provide a non-reliabilist account of propositional justification (i.e., evidential support). We then invoke this account, together with the notion of a transglobally reliable belief-forming process, to give an account of doxastic justification.

The ancient sorites paradox has important implications for metaphysics, for logic, and for semantics. Metaphysically, the paradox can be harnessed to produce a powerful argument for the claim that there cannot be vague objects or vague properties. With respect to logic, the paradox forces a choice between the highly counterintuitive ‘epistemic’ account of vagueness and the rejection of classical two-valued logic. Regarding semantics, nonclassical approaches to the logic of vagueness lead naturally to the idea that truth, for vague discourse, is not direct language-world correspondence grounded in referential connections linking a statement’s basic subsentential constituents (names, predicates, the apparatus of quantification) to real objects and real properties; rather, truth is a matter of indirect correspondence between vague language and nonvague reality

I advocate a two part view concerning vagueness. On one hand I claim that vagueness is logically incoherent; but on the other hand I claim that vagueness is also a benign, beneficial, and indeed essential feature of human language and thought. I will call this view transvaluationism, a name which seems to me appropriate for several reasons. First, the term suggests that we should move beyond the idea that the successive statements in a sorites sequence can be assigned differing truth values in some logically coherent way that fully respects the nature of vagueness -a way that [1] fully eschews any arbitrarily precise semantic transitions. We should transcend this impossible goal by accepting that vagueness harbors logical incoherence. Second, just as Nietzsche held that one can overcome nihilism by embracing what he called the transvaluation of all values, my position affirms vagueness, rather than despairing in the face of the logical absurdity residing at its very core. This affirmation amounts to a transvaluation of truth values, as far as sorites sequences are concerned. Third, the term ’transvaluationism’ has a nice ring to it, especially since one of the principal philosophical approaches to vagueness is called supervaluationism. I will call the first claim of transvaluationism, that vagueness is logically incoherent, the incoherence thesis . I will call the second claim, that vagueness is benign, beneficial, and essential, the legitimacy thesis . The legitimacy thesis, taken by itself, seems overwhelmingly plausible; anyone who denies it assumes a heavy burden of proof. But prima facie, it seems dubious that the legitimacy thesis can be maintained in conjunction with the incoherence thesis. For, there is reason to doubt whether there is any cogent way to embrace the incoherence thesis without thereby becoming mired in what Williamson (1994) calls global nihilism about vagueness -the view that vague terms are empty (i.e., they do not, and cannot, apply to anything). Global nihilism, Williamson argues, has such destructively negative consequences that it does not deserve to be taken seriously -for instance, the consequence that vastly many of our common sense beliefs are false, and the consequence that these beliefs are not even useful (since the constituent terms in ’Common sense beliefs are useful’ are vague and hence this statement turns out, given the [2] incoherence thesis, to be false itself). In short, the idea that one can adopt the incoherence thesis and then somehow transcend nihilism might initially seem hopelessly optimistic; transvaluationism would then be an unattainable, chimerical, goal rather than an intelligible and conceptually stable position concerning vagueness. Given certain widely held philosophical views about how language and thought must map onto the world in order for statements and the beliefs they express to be true -views that fall appropriately under the label ’referential semantics’ -transvaluationism probably is a chimerical goal.
