Billy Dunaway develops and defends a framework for realism about morality. He defends the idea that moral properties are privileged parts of reality which are the referents for our moral terms. He suggests how it is that we can know about morality, and what the limits to moral disagreement are.

This paper looks at the phenomenon of ethical vagueness by asking the question, how ought one to reason about what to do when confronted with a case of ethical vagueness? I begin by arguing that we must confront this question, since ethical vagueness is inescapable. I then outline one attractive answer to the question: we ought to maximize expected moral value when confronted with ethical vagueness. This idea yields determinate results for what one rationally ought to do in cases of (...) ethical vagueness. But what it recommends is dependent on which substantive theory of vagueness is true; one can't draw conclusions about how to reason about vagueness in ethics in the absence of concrete assumptions about the nature of vagueness.

Quasi-realist Expressivists offer accounts of normative truth, normative facts, and normative properties which make their view apparently indistinguishable from Realist views on these subjects. This chapter explores the idea that there is still a substantial metaphysical difference between Realism and Quasi-realism, since they differ over the extent to which normative properties are metaphysically elite in David Lewis’s sense. Eliteness is an explanatory notion, and Realists need the explanatory features of eliteness to explain how different communities refer to the same property (...) with their word “ought.” While Quasi-realists can agree with Realists about which property “ought” refers to, the same resources they use to explain normative truth, reference, and facthood also explain why the referential facts are this way. Thus eliteness does not enter the explanatory picture for the Quasi-realist, and the metaphysics of obligation looks very different on the Realist and Quasi-realist views. (shrink)

This paper is about avoiding commitment to an ontology of possible worlds with two primitives: a hyperintensional connective like ‘in virtue of’, and primitive quantification into predicate position. I argue that these tools (which some believe can be independently motivated) render dispensable the ontology of possible worlds needed by traditional anaylses of modality. They also shed new light on the notion of truth-at-a-world.

James Dreier (Philos Perspect 18: 23-44, 2004) states what he calls the "Problem of Creeping Minimalism": that metaethical Expressivists can accept a series of claims about meaning, under which all of the sentences that Realists can accept are consistent with Expressivism. This would allow Expressivists to accept all of the Realist's sentences, and as Dreier points out, make it difficult to say what the difference between the two views is. That Expressivists can accept these claims about meaning has been suggested (...) by Simon Blackburn on behalf of his "quasirealist". I argue against the assumption that there is a way to interpret the Realist's sentences in a way that renders them consistent with Expressivism. (shrink)

To what extent are the answers to theological questions knowable? And if the relevant answers are knowable, which sorts of inquirers are in a position to know them? In this chapter we shall not answer these questions directly but instead supply a range of tools that may help us make progress here. The tools consist of plausible structural constraints on knowledge. After articulating them, we shall go on to indicate some ways in which they interact with theological scepticism. In some (...) cases the structural constraints bear directly on whether one can know answers to theological questions. But the structural considerations are related to theological scepticism in other interesting ways as well; for instance we will also be using them to explore the significance of scepticism, by addressing questions such as ‘To what extent does it matter whether or not we can know the answer to theological questions?’.

It is not an exaggeration to say that Allan Gibbard is one of the most significant contributors to philosophy over the last five decades. Gibbard's work covers an impressive number of subfields within philosophy, including ethics, philosophy of language, decision theory, epistemology, and metaphysics. It also engages with, and makes significant contributions to, work from the natural and social sciences. This volume is not a collection of artifacts from past decades of philosophy. Instead, it is a collection of essays that (...) each make a significant contribution to contemporary work in philosophy. This reflects the fact that Gibbard's work has not only had a massive influence on past discussion in philosophy but also continues to influence new directions of philosophical research. With contributions from: Sara Aronowitz, Simon Blackburn, Paul Boghossian, David Braddon-Mitchell, Nate Charlow, Stephen Darwall, Jamie Dreier, Billy Dunaway, Melissa Fusco, Sona Ghosh, Allan Gibbard, Bill Harper, Paul Horwich, Zoë Johnson King, Tristram McPherson, Howard Nye, Lauren Olin, Caleb Perl, David Plunkett, Peter Railton, Connie Rosati, Mark Schroeder, Alex Silk, Daniel J.

Anti-realism is often claimed to be preferable to realism on epistemological grounds: while realists have difficulty explaining how we can ever know claims if we are realists about it, anti-realism faces no analogous problem. This paper focuses on anti-realism about normativity to investigate this alleged advantage to anti-realism in detail. I set up a framework in which a version of anti-realism explains a type of modal reliability that appears to be epistemologically promising, and plausibly explains the appearance of an epistemological (...) advantage to realism. But, I argue, this appearance is illusory, and on closer investigation the anti-realist view does not succeed in explaining the presence of familiar epistemological properties for normative belief like knowledge or the absence of defeat. My conclusion on the basis of this framework is that there is a tension in the anti-realist view between the urge to idealize the conditions in which normative beliefs ground normative facts, and a robust kind of reliability that normative belief can have if the anti-realist resists these idealizations.

This paper advances two theses about evolutionary debunking arguments in ethics. The first is that, while such arguments are often motivated with the rhetoric of ‘luck', proponents of these arguments have not distinguished between the kinds of luck that might lead to the formation of a true belief. Once we make the needed distinctions, the relevance of the kind of luck which can be derived from broadly evolutionary explanations to the epistemological conclusions debunkers draw is suspect. The second thesis is (...) that debunkers might successfully show that epistemic luck is relevant to their concerns. But they will need to include specific premises about the kind of evolutionary mechanism that explains the beliefs that the debunker targets. Proponents of debunking arguments, if they continue to insist on using luck-based considerations, are then hostage to empirical fortune in a way not previously recognized. (shrink)

This article sketches how the debate over divine predications should be informed by the medieval Islamicate tradition. We emphasize the focus not only on the metaphysics and language of divine predications by al-Ghazali, Maimonides, and others, but also on the epistemology of divine predications. In particular, we emphasize the importance of a theory that explains not only what it takes to make a divine predication true, but also whether these predications are knowable. The epistemological element is central, because traditional views (...) of theology aim to avoid theological skepticism, which is the view that, even if there are theological truths, these truths are unknowable. We pursue this point by emphasizing the role of substantives in al-Ghazalı’s theory of divine predicates, and Maimonides’s discussion of negative predications. In closing we apply these lessons to some recent discussions of theological predication. (shrink)

It is often claimed that realism about normativity entails that it is difficult for us to know anything about it. I refine this thought by characterizing realism as a thesis which is committed to explaining a semantic thesis about possible uses of normative language: that normative terms like ‘ought’ are semantically stable, in the sense that the term refers to the same property even if it is used differently. There are independent arguments which show that a realist view, if it (...) is plausible, should entail semantic stability for ‘ought’. In this paper I argue that, if the realist succeeds in explaining semantic stability, the realist view implies that normative beliefs will be at risk of being false, and hence not knowledge. Central to this argument is a phenomenon I call meta-semantic risk. I argue that the phenomenon of meta-semantic risk gives rise to a significant dose of normative skepticism for the realist, but it does not entail wholesale skepticism, since the epistemic threats are only contingent, and threatens only precise normative beliefs. I close by sketching two arguments that may show that even this limited form of skepticism counts significantly against the realist view. (shrink)

Philosophers and theologians have traditionally been impressed with arguments which purport to show that predicates such as ‘wise,’ ‘good,’ and ‘powerful’ cannot, when applied to God, mean what they ordinarily mean when applied to everyday creatures. Theological predications, according to these arguments, cannot be univocal with ordinary predications. Philosophers in the Jewish, Christian, and Islamic traditions presented accounts of how non-univocal theological predications could be true of God. These are commonly known as analogical and apophatic accounts of the divine predicates. (...) In this paper, I argue that representatives from each tradition also took epistemological constraints on an account of theological predication seriously. That is, they took it to be important to show not only how a predicate could be true of God, but also how we could know that it is true. Epistemological constraints of this kind, I argue, are non-trivial, since many accounts of the truth of theological predications entail that it is impossible or difficult to know them. Moreover, epistemological constraints are also important for ongoing discussions of theological predication, as they are violated by several contemporary accounts in the literature. (shrink)

Much of experimental philosophy consists of surveying 'folk' intuitions about philosophically relevant issues. Are the results of these surveys evidence that the relevant folk intuitions cannot be predicted from the ‘armchair’? We found that a solid majority of philosophers could predict even results claimed to be 'surprising'. But, we argue, this does not mean that such experiments have no role at all in philosophy.

Oxford Studies in Metaethics is the only publication devoted exclusively to original philosophical work in the foundations of ethics. It provides an annual selection of much of the best new scholarship being done in the field.

Bringing together powerful new tools from set theory and the philosophy of language, this book proposes a solution to one of the few unresolved paradoxes from antiquity, the Paradox of the Liar. Treating truth as a property of propositions, not sentences, the authors model two distinct conceptions of propositions: one based on the standard notion used by Bertrand Russell, among others, and the other based on J.L. Austin's work on truth. Comparing these two accounts, the authors show that while the (...) Russellian conception of the relation between sentences, propositions, and truth is crucially flawed in limiting cases, the Austinian perspective has fruitful applications to the analysis of semantic paradox. In the course of their study of a language admitting circular reference and containing its own truth predicate, Barwise and Etchemendy also develop a wide range of model-theoretic techniques--based on a new set-theoretic tool, Peter Aczel's theory of hypersets--that open up new avenues in logical and formal semantics.

The present volume collects some of Barwise's papers written since then, those directly concerned with relations among logic, situation theory, and situation semantics. Several papers appear here for the first time.

Situation theory is the result of an interdisciplinary effort to create a full-fledged theory of information. Created by scholars and scientists from cognitive science, computer science, AI, linguistics, logic, philosophy, and mathematics, the theory is forging a common set of tools for the analysis of phenomena from all these fields. This volume presents work that evolved out of the Second Conference on Situation Theory and its Applications. Twenty-six essays exhibit the wide range of the theory, covering such topics as natural (...) language semantics, philosophical issues about information, mathematical applications, and the visual representation of information in computer systems.Jon Barwise is a professor of philosophy, mathematics, and logic at Indiana University in Bloomington. Jean Mark Gawron is a researcher at SRI International and a consultant at Hewlett-Packard Laboratories. Gordon Plotkin is a professor of theoretical computer science at the University of Edinburgh.

Jon Elster has written a comprehensive, wide-ranging book on the emotions in which he considers the full range of theoretical approaches. Drawing on history, literature, philosophy and psychology, Elster presents a complete account of the role of the emotions in human behaviour. While acknowledging the importance of neurophysiology and laboratory experiment for the study of emotions, Elster argues that the serious student of the emotions can learn more from the great thinkers and writers of the past, from Aristotle to Jane (...) Austen. He attaches particular importance to the work of the French moralists, notably La Rochefoucauld, who demonstrated the way esteem and self-esteem shape human motivation. The book also maintains a running dialogue with economists and rational-choice theorists. Combining methodological and theoretical arguments with empirical case-studies and written with Elster's customary verve and economy, this book has great cross-disciplinary appeal. (shrink)

The chapter explores whether, or to what extent, recent work in experimental philosophy puts pressure on the idea that the concept of causation is ‘egalitarian’. Causal selection – where experimental subjects tend to rate the causal strength of (for example) a norm-violator more strongly than a non-norm-violator – is a well established phenomenon, and is in prima facie tension with an egalitarian conception of causation; it also, indirectly, puts prima facie pressure on the idea that causation is a worldly phenomenon (...) whose obtaining is independent of facts about norms. The chapter explores both the various psychological mechanisms and the broadly pragmatic approaches to explaining causal selection. It argues that the answer to the question whether or not the concept of causation is egalitarian is currently significantly empirically underdetermined, and suggests some avenues for further investigation.

Professionalism requires that physicians uphold the best interests of patients while simultaneously insuring just use of health care resources. Current articulations of these obligations like the American Board of Internal Medicine Foundation's Physician Charter do not reconcile how these obligations fit together when they conflict. This is the problem of dual agency. The most common ways of dealing with dual agency: “bunkering”—physicians act as though societal cost issues are not their problem; “bailing”—physicians assume that they are merely agents of society (...) and deliver care typically based on a strongly consequentialist public health ethic; or “balancing”—a vaguely specified attempt to uphold both patient welfare and societal need for judicious resource use simultaneously—all fail. Here I propose how the problem of dual agency might begin to be addressed with rigor and consistency. Without dealing with the dual agency problem and getting more specific about how to reconcile its norms when they conflict, the expectations of professionalism risk being written off as cute, nonbinding aphorisms from the medical profession.

The detailed analysis of a particular quasi-historical numerical example is used to illustrate the way in which a Bayesian personalist approach to scientific inference resolves the Duhemian problem of which of a conjunction of hypotheses to reject when they jointly yield a prediction which is refuted. Numbers intended to be approximately historically accurate for my example show, in agreement with the views of Lakatos, that a refutation need have astonishingly little effect on a scientist's confidence in the ‘hard core’ of (...) a successful research programme even when a comparable confirmation would greatly enhance that confidence.

The term “virtual reality” was first coined by Antonin Artaud to describe a value-adding characteristic of certain types of theatrical performances. The expression has more recently come to refer to a broad range of incipient digital technologies that many current philosophers regard as a serious threat to human autonomy and well-being. Their concerns, which are formulated most succinctly in “brain in a vat”-type thought experiments and in Robert Nozick's famous “experience machine” argument, reflect a fundamental misunderstanding of the way that (...) such technologies would probably have to work. They also considerably underestimate the positive contributions that virtual reality technologies could make to the growth of human knowledge. Here, we examine and critique Nozick's claim that no reasonable person would want to plug into his hypothetical experience machine in light of a broadly enactivist understanding of how future VR technologies might be expected to function. We then sketch out a tentative theory of the phenomenon of truth in fiction, in order to characterize some of the distinct epistemic opportunities that VR technologies promise to provide. (shrink)

We evaluate here the performance of four models of cross-situational word learning: two global models, which extract and retain multiple referential alternatives from each word occurrence; and two local models, which extract just a single referent from each occurrence. One of these local models, dubbed Pursuit, uses an associative learning mechanism to estimate word-referent probability but pursues and tests the best referent-meaning at any given time. Pursuit is found to perform as well as global models under many conditions extracted from (...) naturalistic corpora of parent-child interactions, even though the model maintains far less information than global models. Moreover, Pursuit is found to best capture human experimental findings from several relevant cross-situational word-learning experiments, including those of Yu and Smith (), the paradigm example of a finding believed to support fully global cross-situational models. Implications and limitations of these results are discussed, most notably that the model characterizes only the earliest stages of word learning, when reliance on the co-occurring referent world is at its greatest.

It is tempting to analyse causality in terms of just one of the indicators of causal relationships, e.g., mechanisms, probabilistic dependencies or independencies, counterfactual conditionals or agency considerations. While such an analysis will surely shed light on some aspect of our concept of cause, it will fail to capture the whole, rather multifarious, notion. So one might instead plump for pluralism: a different analysis for a different occasion. But we do not seem to have lots of different concepts of cause (...) – just one eclectic notion. The resolution of this conundrum, I think, requires us to accept that our causal beliefs are generated by a wide variety of indicators, but to deny that this variety of indicators yields a variety of concepts of cause. This focus on the relation between evidence and causal beliefs leads to what I call epistemic causality. Under this view, certain causal beliefs are appropriate or rational on the basis of observed evidence; our notion of cause can be understood purely in terms of these rational beliefs. Causality, then, is a feature of our epistemic representation of the world, rather than of the world itself. This yields one, multifaceted notion of cause. (shrink)

The Recursive Bayesian Net (RBN) formalism was originally developed for modelling nested causal relationships. In this paper we argue that the formalism can also be applied to modelling the hierarchical structure of mechanisms. The resulting network contains quantitative information about probabilities, as well as qualitative information about mechanistic structure and causal relations. Since information about probabilities, mechanisms and causal relations is vital for prediction, explanation and control respectively, an RBN can be applied to all these tasks. We show in particular (...) how a simple two-level RBN can be used to model a mechanism in cancer science. The higher level of our model contains variables at the clinical level, while the lower level maps the structure of the cell's mechanism for apoptosis. (shrink)

Standard accounts of semantics for counterfactuals confront the true–true problem: when the antecedent and consequent of a counterfactual are both actually true, the counterfactual is automatically true. This problem presents a challenge to safety-based accounts of knowledge. In this paper, drawing on work by Angelika Kratzer, Alan Penczek, and Duncan Pritchard, we propose a revised understanding of semantics for counterfactuals utilizing machinery from generalized quantifier theory which enables safety theorists to meet the challenge of the true–true problem.

Kyburg goes half-way towards objective Bayesianism. He accepts that frequencies constrain rational belief to an interval but stops short of isolating an optimal degree of belief within this interval. I examine the case for going the whole hog.

Part I of this paper introduces a range of mechanistic theories of causality, including process theories and the complex-systems theories, and some of the problems they face. Part II argues that while there is a decisive case against a purely mechanistic analysis, a viable theory of causality must incorporate mechanisms as an ingredient, and describes one way of providing an analysis of causality which reaps the rewards of the mechanistic approach without succumbing to its pitfalls.

The mechanistic and causal accounts of explanation are often conflated to yield a ‘causal-mechanical’ account. This paper prizes them apart and asks: if the mechanistic account is correct, how can causal explanations be explanatory? The answer to this question varies according to how causality itself is understood. It is argued that difference-making, mechanistic, dualist and inferentialist accounts of causality all struggle to yield explanatory causal explanations, but that an epistemic account of causality is more promising in this regard.

It is argued in this paper that the valid argument forms coming under the general heading of Demonstrative Induction have played a highly significant role in the history of theoretical physics. This situation was thoroughly appreciated by several earlier philosophers of science and deserves to be more widely known and understood.
