Moral psychologists have recently turned their attention to a phenomenon they call 'moral dumbfounding'. Moral dumbfounding occurs when someone confidently pronounces a moral judgment, then finds that he or she has little or nothing to say in defense of it. This paper addresses recent attempts by Jonathan Haidt and Marc Hauser to make sense of moral dumbfounding in terms of their respective theories of moral judgment; Haidt in terms of a 'social intuitionist' model of moral judgment, and Hauser in terms (...) of his 'Rawlsian creature' model of moral judgment. I show that Haidt and Hauser assume that moral dumbfounding is to be explained in terms of features of a.) moral judgment that are b.) construed in terms of the intrinsic features of individuals. By contrast, I hypothesize that moral dumbfounding is to be explained in terms of moral reasoning, more specifically in terms of the social dynamics of such reasoning. Finally, I argue that this hypothesis points towards an externalistic account of both moral reasoning and moral judgment. (shrink)

In this paper, I motivate skepticism about the causal efficacy of moral properties in two ways. First, I highlight a tension that arises between two claims that moral realists may want to accept. The first claim is that physically indistinguishable things do not differ in any causally efficacious respect. The second claim is that physically indistinguishable things that differ in certain historical respects have different moral properties. The tension arises to the extent to which these different moral properties are supposed (...) to have different effects on people. I will introduce a class of cases in which this tension arises and suggest that the moral properties in these cases have no causal power. I will also question whether there are differences between the moral properties in these cases and moral properties in other cases that do not involve physically indistinguishable things that could make the latter moral properties causally efficacious. The second way that I motivate skepticism consists in pointing out a unique feature of cases in which moral properties are supposed both to supervene on historical properties and to be causally efficacious. These cases allow us to change moral properties with alleged effects while we hold constant the nonmoral candidates for causal contribution to those effects. This feature of these cases is unique because in most other cases the moral properties supervene on the physical properties in the nonmoral candidates, such that we cannot change the former while holding constant the latter. This way of changing moral properties provides empirical grounds for testing their causal efficacy. (shrink)

The ' argument from queerness', made famous by J. L. Mackie, remains one of the most influential arguments in metaethics. However, many philosophers focus on just one or two of its strands, while others assume a particular but by no means universal reading of it. This essay attempts to disentangle and evaluate all strands of the argument. Surprisingly, when this is done, not much is left as a distinct argument from queerness. Much of the argument collapses into other types of (...) argument, and what is left, though intuitively appealing, is not viable as philosophical argument. (shrink)

I defend a naturalist theory of moral justification, "Confirmation Theory", from an objection raised by David Copp and Geoffrey Sayre-McCord. Confirmation Theory holds that some moral theory is justified because it is needed in the best empirical explanation of the world. The objection is that moral explanations are "incidental", that even if a moral theory is indispensable, this doesn't establish that any moral standard is justified. I show that the naturalist can concede that moral explanations are incidental and still maintain (...) the attractive elements of Confirmation Theory. (shrink)

We elucidate the conditions under which any hypothesis is explanatorily relevant by analyzing several tests of explanatory relevance and explanations based on those tests. A new causal criterion of explanatory relevance is developed and defended. We show how the causal criterion succeeds in establishing, at the very least, a very strong presumption against moral facts.

This paper seeks to refute one variant of a view that scientific disciplines are intrinsically more objective than non?scientific ones, and that this greater objectivity explains increasing social agreement about the findings of science, by contrast with increasing disagreement about the findings of, e.g., ethics. Such a view rests on the implicit assumption that all forms of discourse aim equally at the generation of consensus; instead, differing degrees of consensus in different disciplines are often explicable by sociological, not metaphysical, differences (...) in the disciplines concerned. A detailed example is presented of a discipline (Indian folk dietary medicine) in which considerable lack of consensus is observed, for sociologically explicable reasons, in spite of its claims to scientific objectivity. It is concluded that disciplines may differ in the degree of truth of the claims advanced in them, and in the importance of consensus among their social aims. But neither of these is to be explained by differences in respect of some independent property of objectivity. (shrink)

An increasingly popular moral argument has it that the story of human evolution shows that we can explain the human disposition to make moral judgments without relying on a realm of moral facts. Such facts can thus be dispensed with. But this argument is a threat to moral realism only if there is no realist position that can explain, in the context of human evolution, the relationship between our particular moral sense and a realm of moral facts. I sketch a (...) plausible evolutionary story that illuminates this relationship. First, the sorts of adaptive pressures facing early humans would have produced more than just potent prosocial emotions, as evolutionary antirealists like to claim; it would have produced judgments—often situated within emotions—to the effect that others could reasonably disapprove of some bit of conduct, for an early human who cared deeply about how others might respond to her action enjoyed the benefits of more cooperative exchanges than those early humans who did not. Second, according to objectivist versions of moral constructivism, moral facts just are facts about how others, ideally situated, would respond to one's conduct. Thus if any objectivist moral constructivism story is true, then we can intelligibly assert that a) our capacity for moral judgment is the product of adaptive pressures acting on early humans and b) some moral judgments are objectively true.

In this paper the author considers a number of objections to the views he expressed in "kant's examples of the first formulation of the categorical imperative" ("the philosophical quarterly", Volume 7, Number 26, January, 1973) by professor kemp in "kant's examples of the categorical imperative" ("the philosophical quarterly", Volume 8, Number 30, January, 1957) and does what he can to reply to them.

In this paper, I argue that an externalist theory of thought content provides the means to resolve two debates in moral philosophy. The first—that between judgement internalism and judgement externalism—concerns the question of whether there is a conceptual connection between moral judgement and motivation. The second—that between reasons internalism and reasons externalism—concerns the relationship between moral reasons and an agent's subjective motivational set. The resolutions essentially stem from the externalist claim that concepts can be grasped partially, and a new moral (...) theory, which I call ‘moral externalism’, emerges. (shrink)

In order to defend the Cornell variety of naturalistic moral realism from Horgan and Timmons’ Moral Twin Earth objection, several philosophers have proposed what I call Normatively Enriched Moral Meta-Semantics. According to NEMMS, the natural properties that serve as the contents of moral predicates are fixed by non- moral normative facts. In this paper, I elucidate two versions of NEMMS: one proposed by David Brink, and the other proposed by Mark van Roojen. I show what these meta-semantics have in common, (...) and how each one promises the Cornell realist a response to the Moral Twin Earth objection. I then argue that Cornell realists ought to be wary of adopting NEMMS. A naturalist realist who adopts this meta-semantics confronts a trilemma. The proponent of NEMMS owes a meta-ethical account of the relevant content-fixing normative facts. Such facts are either reducible to recognizably natural facts or they are not. If they are not reducible, then NEMMS entails the denial of ethical naturalism. If such facts are taken to be reducible to facts about agents’ actual or hypothetical attitudes, then the account renders moral facts stance-dependent. Consequently, moral realism is false. Alternatively, one might propose that the content-fixing normative facts are reducible to attitude-independent natural facts. However, such a proposal is refuted by its own Twin Earth objection.

Michael Ruse has proposed in his recent book Taking Darwin Seriously and elsewhere a new Darwinian ethics distinct from traditional evolutionary ethics, one that avoids the latter's inadequate accounts of the nature of morality and its failed attempts to provide a naturalistic justification of morality. Ruse argues for a sociobiologically based account of moral sentiments, and an evolutionary based casual explanation of their function, rejecting the possibility of ultimate ethical justification. We find that Ruse's proposal distorts, overextends and weakens both (...) Darwinism and naturalism. So we propose an alternative Darwinian metaethics that both remedies the problems in Ruse's proposal and shows how a Darwinian naturalistic account of the moral good in terms of human fitness avoids the naturalistic fallacy and can provide genuine, even if limited, justifications for substantive ethical claims. Thus, we propose to really take Darwin seriously. (shrink)

The author takes up three metaphysical conceptions of morality — realism, projectivism, constructivism — and the account of justification or reason that makes these pictures possible. It is argued that the right meta-ethical conception should be the one that entails the most plausible conception of reason-giving, rather than by any other consideration. Realism and projectivism, when understood in ways consistent with their fundamental commitments, generate unsatisfactory models of justification; constructivism alone does not. The author also argues for a particular interpretation (...) of how “objective moral obligation” is to be understood within constructivism. (shrink)

This paper presents a regress challenge to the selective psychological debunking of moral judgments. A selective psychological debunking argument conjoins an empirical claim about the psychological origins of certain moral judgments to a theoretical claim that these psychological origins cannot track moral truth, leading to the conclusion that the moral judgments are unreliable. I argue that psychological debunking arguments are vulnerable to a regress challenge, because the theoretical claim that ‘such-and-such psychological process is not moral-truth-tracking’ relies upon moral judgments. We (...) must then ask about the psychological origins of these judgments, and then make a further evaluative judgment about these psychological origins… and so on. This chain of empirical and evaluative claims may continue indefinitely and, I will argue, proponents of the debunking argument are in a dialectical position where they may not simply call a halt to the process. Hence, their argument cannot terminate, and its debunking conclusion cannot be upheld. (shrink)

The effects of anthropogenic climate change may be devastating. Nevertheless, most people do not seem to be seriously concerned. We consume as much as we always did, drive as much as we always did, eat as much meat as we always did. What can we do to overcome this collective apathy? In order to be able to develop effective measures, we must first get clear about the causes of climate change inaction. In this paper I ask whether moral nihilism is (...) a significant cause of climate change inaction. The answer to this question depends mainly on the extent to which being a moral nihilist reduces one's likelihood of taking action against climate change. At first sight, the extent seems to be considerable. I argue, however, that this assumption is false. Only slightly more non-nihilists than nihilists are led to climate-friendly actions by moral considerations. And in absolute terms, morality plays such a minor role in leading people to act that the difference is barely noticeable. (shrink)

My first paper on the Is/Ought issue. The young Arthur Prior endorsed the Autonomy of Ethics, in the form of Hume’s No-Ought-From-Is (NOFI) but the later Prior developed a seemingly devastating counter-argument. I defend Prior's earlier logical thesis (albeit in a modified form) against his later self. However it is important to distinguish between three versions of the Autonomy of Ethics: Ontological, Semantic and Ontological. Ontological Autonomy is the thesis that moral judgments, to be true, must answer to a realm (...) of sui generis non-natural PROPERTIES. Semantic autonomy insists on a realm of sui generis non-natural PREDICATES which do not mean the same as any natural counterparts. Logical Autonomy maintains that moral conclusions cannot be derived from non-moral premises.-moral premises with the aid of logic alone. Logical Autonomy does not entail Semantic Autonomy and Semantic Autonomy does not entail Ontological Autonomy. But, given some plausible assumptions Ontological Autonomy entails Semantic Autonomy and given the conservativeness of logic – the idea that in a valid argument you don’t get out what you haven’t put in – Semantic Autonomy entails Logical Autonomy. So if Logical Autonomy is false – as Prior appears to prove – then Semantic and Ontological Autonomy would appear to be false too! I develop a version of Logical Autonomy (or NOFI) and vindicate it against Prior’s counterexamples, which are also counterexamples to the conservativeness of logic as traditionally conceived. The key concept here is an idea derived in part from Quine - that of INFERENCE-RELATIVE VACUITY. I prove that you cannot derive conclusions in which the moral terms appear non-vacuously from premises from which they are absent. But this is because you cannot derive conclusions in which ANY (non-logical) terms appear non-vacuously from premises from which they are absent Thus NOFI or Logical Autonomy comes out as an instance of the conservativeness of logic. This means that the reverse entailment that I have suggested turns out to be a mistake. The falsehood of Logical Autonomy would not entail either the falsehood Semantic Autonomy or the falsehood of Ontological Autonomy, since Semantic Autonomy only entails Logical Autonomy with the aid of the conservativeness of logic of which Logical Autonomy is simply an instance. Thus NOFI or Logical Autonomy is vindicated, but it turns out to be a less world-shattering thesis than some have supposed. It provides no support for either non-cognitivism or non-naturalism.

Someone who knew everything about the world’s physical nature could, apparently, suffer from ignorance about various aspects of conscious experience. Someone who knew everything about the world’s physical and mental nature could, apparently, suffer from moral ignorance. Does it follow that there are ways the world is, over and above the way it is physically or psychophysically? This paper defends a negative answer, based on a distinction between knowing the fact that p and knowing that p. This distinction is made (...) intelligible by reference to criterial connections between the possession of moral or phenomenal knowledge, and the satisfaction of cognitively neutral conditions of desire and experiential history. The existence of such connections in the moral case makes for an efficient dissolution of the so-called moral problem. (shrink)

Debunking arguments typically attempt to show that a set of beliefs or other intensional mental states bear no appropriate explanatory connection to the facts they purport to be about. That is, a debunking argument will attempt to show that beliefs about p are not held because of the facts about p. Such beliefs, if true, would then only be accidentally so. Thus, their causal origins constitute an undermining defeater. Debunking arguments arise in various philosophical domains, targeting beliefs about morality, the (...) existence of God, logic, and others. They have also arisen in material-object metaphysics, often aimed at debunking common-sense ontology. And while most of these arguments feature appeals to ‘biological and cultural contingencies’ that are ostensibly responsible for our beliefs about which kinds of objects exist, few of them take a serious look at what those contingencies might actually be. The purpose of this paper is twofold. First, to remedy this by providing empirical substantiation for a key premise in these debunking arguments by examining data from cognitive science, evolutionary biology, and developmental psychology that support a ‘debunking explanation’ of our common-sense beliefs and intuitions about which objects exist. Second, to argue that such data also undermines a particular kind of rationalist defense of common-sense ontology, sometimes employed as a response to the debunking threat. (shrink)

Philosophical theorizing is often, either tacitly or explicitly, guided by intuitions about cases. Theories that accord with our intuitions are generally considered to be prima facie better than those that do not. However, recent empirical work has suggested that philosophically significant intuitions are variable and unstable in a number of ways. This variability of intuitions has led naturalistically inclined philosophers to disparage the practice of relying on intuitions for doing philosophy in general (e.g. Stich & Weinberg 2001) and for doing (...) moral philosophy in particular (Appiah 2008; Doris & Stich 2005; Horowitz 1998; Nadelhoffer & Feltz 2008; Sinnott Armstrong 2008). In this paper, we will draw on naturalistic considerations to offer some solace to philosophers who rely on intuitions. We wouldn’t call this a defense of intuitions, exactly, since we are sympathetic with much of the naturalists’ critique. But we want to introduce into the debate some neglected naturalistic reasons to be optimistic about intuitions, focusing especially on ethical intuitions. (shrink)

Alexander Miller has recently considered an ingenious extension of Frank Jackson and Philip Pettit's account of 'program explanation' as a way of defending non-reductive naturalist versions of moral realism against Harman's explanatory criticism. Despite the ingenuity of this extension, Miller concludes that program explanation cannot help such moral realists in their attempt to defend moral properties. Specifically, he argues that such moral program explanations are dispensable from an epistemically unlimited point of view. I show that Miller's argument for this negative (...) claim is inadequate, and that he has, in spite of himself, identified a promising defence of moral realism. (shrink)

Charles Pigden has argued for a logical Is/Ought gap on the grounds of the conservativeness of logic. I offer a counter-example which shows that Pigden’s argument is unsound and that there need be no logical gap between Is-premises and an Ought-conclusion. My counter-example is an argument which is logically valid, has only Is-premises and an Ought-conclusion, does not purport to violate the conservativeness of logic, and does not rely on controversial assumptions about Aristotelian biology or 'institutional facts.'.

In this paper I will argue that this entire dialectic is somewhat misguided. The mental states which are generally assumed to fall under the category of ‘intuition’ likely comprise a highly heterogeneous group; from the point of view of psychology or of neuroscience, in fact, ‘intuitions’ appear to be generated by several fundamentally different sorts of mental processes. If this is correct, then the term ‘intuition’ may simply carve things too broadly. I will argue that it is a mistake to (...) focus on the ‘reliability of intuition’; empirical evidence suggests that the reliability of one type of intuition may tell us next to nothing about the reliability of other types. Rather than debating the evidential status of intuition as a whole, philosophers interested in methodology would do well to focus their investigations much more narrowly. (shrink)

In his recent book Error Theory: History, Critique, Defence, Jonas Olson attempts to revive the argument from queerness originally made famous by J.L. Mackie. In this paper, we do three things. First, we eliminate four untenable formulations of the argument. Second, we argue that the most plausible formulation is one that depends crucially upon considerations of parsimony. Finally, we evaluate this formulation of the argument. We conclude that it is unproblematic for proponents of moral non-naturalism—the target of the argument from (...) queerness. (shrink)

Recent work in various branches of philosophy has reinvigorated debate over the psychology behind moral judgment. Using Marc Hauser's categorization of theories as “Kantian,” “Humean,” or “Rawlsian” to frame the discussion, I argue that the existing evidence weighs against the Kantian model and partly in favor of both the Humean and the Rawlsian models. Emotions do play a causal role in the formation of our moral judgments, as the Humean model claims, but there are also unconscious principles shaping our moral (...) judgments, as the Rawlsian model predicts. Thus, Hauser's tripartite division of possible models of moral psychology is inadequate. Drawing on research in cognitive neuroscience, clinical and behavioral psychology, and psychopathology, I sketch a new, developmental sentimentalist model of moral psychology. I call it a “Mencian” model, after the Confucian philosopher Mencius. On this model, moral judgments are caused by emotions, but because of the way emotions are mapped onto particular actions, moral judgments unconsciously reflect certain principled distinctions.

One class of central debates between normative realists appears to concern whether we should be naturalists or reductionists about the normative. However, metaethical discussion of naturalism and reduction is often inconsistent, murky, or uninformative. This can make it hard to see why commitments relative to these metaphysical categories should matter to normative realists. This paper aims to clarify the nature of these categories, and their significance in debates between normative realists. I develop and defend what I call the joint-carving taxonomy, (...) which builds on David Lewis’ notion of elite properties. I argue that this taxonomy is clear and metaphysically interesting, and answers to distinctive taxonomic interests of normative realists. I also suggest that it has important implications for the project of adjudicating debates among normative realists. (shrink)

On the face of it, some of our knowledge is of moral facts (for example, that this promise should not be broken in these circumstances), and some of it is of non-moral facts (for example, that the kettle has just boiled). But, some argue, there is reason to believe that we do not, after all, know any moral facts. For example, according to J. L. Mackie, if we had moral knowledge (‘‘if we were aware of [objective values]’’), ‘‘it would have (...) to be by some special faculty of moral perception or intuition, utterly different from our ordinary ways of knowing everything else’’(1977,p.38).But wehavenosuchspecialfaculty.So,wehavenomoralknowledge. Following Mackie, let us distinguish two questions: Q1: Assuming that we have moral knowledge, how do we have it? Q2: Do we in fact have any moral knowledge? In response to the first question, I argue that if we have moral knowledge, we have some of it in the same way we have knowledge of our immediate environment: by perception. Many people think that this answer leads to moral skepticism, because they think that we obviously cannot have moral knowledge by perception. But I will argue that this is incorrect. The plan for the paper is as follows. In Sections 2–4, I work up to my answer to Q1 by considering rivals. In Section 5, I explain what marks my answer to Q1 as a distinctive view, and defend it. In Section 6, I briefly discuss how this answer to Q1 affects what we say in response to Q2. (shrink)

The purpose of this paper is to demonstrate that Francis Hutcheson’s moral sense theory offers a satisfactory account of moral perception. I introduce Hutcheson’s work in §1 and indicate why the existence of a sixth sense is not implausible. I provide a summary of Robert Cowan and Robert Audi’s respective theories of evaluative perception in §2, identifying three problematic objections: the Directness Objection to Cowan’s ethical perception and the aesthetic and perceptual model objections to Audi’s moral perception. §3 examines Hutcheson’s (...) moral sense theory, focusing on his discussion of benevolence, the desire for the happiness of others. I deal with the unresolved issues in Hutcheson’s account by recourse to Charles Darwin’s evolutionary perspective on the moral sense in §4, arguing for the moral sense as the second-order faculty for judging benevolence. I return, in §5, to the objections, showing that moral sense theory solves all three problems and therefore offers a satisfactory account of moral perception. (shrink)

The metaphysical dispute between moral realists and antirealists is cast in terms of properties: the realist holds that moral properties exist, the antirealist denies this claim. There is a longstanding philosophical dispute over the nature of properties, and the obscurity of properties may make the realist/antirealist dispute even more obscure. In the spirit of deflationary theories of truth, we can turn to a deflationary theory of properties in order to clarify this issue. One might reasonably worry that such an account (...) of properties would not be capable of properly characterizing disputes regarding the existence or nonexistence of genuine moral properties. In this paper, I will show that, within this framework, the traditional disputes over the existence of moral properties can be characterized in a far clearer fashion than is usually the case. A deflationary account of properties, along with an explanatory hierarchy of properties, makes the dispute in ontology clear. (shrink)

One of the primary motivations behind moral anti-realism is a deep-rooted scepticism about moral knowledge. Moral realists attempt counter this worry by sketching a plausible moral epistemology. One of the most radical proposals in the recent literature is that we know moral facts by perception – we can literally see that an action is wrong, etc. A serious objection to moral perception is the causal objection. It is widely conceded that perception requires a causal connection between the perceived and the (...) perceiver. But, the objection continues, we are not in appropriate causal contact with moral properties. Therefore, we cannot perceive moral properties. This papers demonstrates that the causal objection is unsound whether moral properties turn out to be secondary, natural properties; non-secondary, natural properties; or non-natural properties. 1.

One popular reason for rejecting moral realism is the lack of a plausible epistemology that explains how we come to know moral facts. Recently, a number of philosophers have insisted that it is possible to have moral knowledge in a very straightforward way—by perception. However, there is a significant objection to the possibility of moral perception: it does not seem that we could have a perceptual experience that represents a moral property, but a necessary condition for coming to know that (...) X is F by perception is the ability to have a perceptual experience that represents something as being F . Call this the ‘Representation Objection’ to moral perception. In this paper I argue that the Representation Objection to moral perception fails. Thus I offer a limited defense of moral perception. (shrink)

Some in public relations have suggested that practitioners adopt a philosophy of enlightened self-interest as an ethical baseline. The author contends that such a theory must be rejected because even the enlightened variety does not adequately weigh the needs of significant others - a central consideration in any effort to define ethical behavior. The author maintains that genuine sacrifice - at times required of those desiring to do the right thing - clearly can conflict with any theory espousing self-interest as (...) a baseline. Further, there is a social dimension to ethics. By virtue of occupational title, the author holds that public relations practitioners have a particular responsibility to advance the social order. Ethical behavior - especially as it relates to public relations - must go well beyond a narrow concern that no injustice is done to individual persons. (shrink)

The use of other animals for human purposes is as contentious an issue as one is likely to find in ethics. And this is so not only because there are both passionate defenders and opponents of such use, but also because even among the latter there are adamant and diametric differences about the bases of their opposition. In both disputes, the approach taken tends to be that of applied ethics, by which a position on the issue is derived from a (...) fundamental moral commitment. This commitment in turn depends on normative ethics, which investigates the various moral theories for the best fit to our moral intuitions. Thus it is that the use of animals in biomedical research is typically defended by appeal to a utilitarian theory, which legitimates harm to some for the greater good of others; while the opposition condemns that use either by appeal to the same theory, but disagreeing about the actual efficacy of animal experimentation, or by appeal to an alternative theory, such as the right of all sentient beings not to be exploited. Unfortunately, the normative issue seems likely never to be resolved, hence leaving the applied issue in limbo. The present essay seeks to circumvent this impasse by dispensing altogether with any moral claim or argument, thereby cutting the Gordian knot of animal ethics with a meta-ethical sword. The alternative schema defended is simply to advance relevant considerations, whereupon “there is nothing left but to feel.” In a word, motivation replaces justification. (shrink)

Discussion of moral explanation has reached an impasse, with proponents of contemporary ethical naturalism upholding the explanatory integrity of moral facts and properties, and opponents--including both antirealists and non-naturalistic realists--insisting that such robustly explanatory pretensions as moral theory has be explained away. I propose that the key to solving the problem lies in the question whether instances of moral properties are causally efficacious. It is argued that, given the truth of contemporary ethical naturalism, moral properties are causally efficacious if the (...) properties of the special sciences are. (shrink)

There is a familiar argument for the falsity of determinism, an argument that proceeds from the claim that agents are morally responsible. A number of authors have challenged the soundness of this argument. I pose a different challenge, one that grants its soundness. The challenge is that, given certain plausible assumptions, one cannot know the conclusion of this argument on the basis of knowing its premises. That is, one cannot know that determinism is false on the basis of this argument (...) even if agents are in fact morally responsible and moral responsibility is in fact incompatible with determinism. A slightly different version of the challenge tells also against the claim that one can be justified in believing that determinism is false on the basis of the argument, so that the challenge cannot be evaded by a retreat to an epistemic position weaker than knowledge. I compare my challenge to the challenge posed by the external world sceptic, and argue that there are asymmetries between these challenges that make it reasonable to accept the former and reject the latter. I close by considering the prospects for developing an epistemology of moral responsibility that is adequate to answer the challenge. (shrink)

A main thread of the debate over mathematical realism has come down to whether mathematics does explanatory work of its own in some of our best scientific explanations of empirical facts. Realists argue that it does; anti-realists argue that it doesn't. Part of this debate depends on how mathematics might be able to do explanatory work in an explanation. Everyone agrees that it's not enough that there merely be some mathematics in the explanation. Anti-realists claim there is nothing mathematics can (...) do to make an explanation mathematical ; realists think something can be done, but they are not clear about what that something is. I argue that many of the examples of mathematical explanations of empirical facts in the literature can be accounted for in terms of Jackson and Pettit's [1990] notion of program explanation, and that mathematical realists can use the notion of program explanation to support their realism. This is exactly what has happened in a recent thread of the debate over moral realism. I explain how the two debates are analogous and how moves that have been made in the moral realism debate can be made in the mathematical realism debate. However, I conclude that one can be a mathematical realist without having to be a moral realist. (shrink)

One of the central tasks of meta-ethical inquiry is to accommodate the common-sense assumptions deeply embedded in our moral discourse. A comparison of the potential of secular and theistic ethics shows that, in the end, theists have a greater facility in achieving this accommodation task; it is easier to appreciate the action-guiding authority and binding nature of morality in a theistic rather than in a secular context. Theistic ethics has a further advantage in being able to accommodate not only this (...) essential conceptual feature of morality, but also the existence of moral requirements and their source of normativity.

Cornell realists claim, among other things, that moral knowledge can be acquired in the same basic way that scientific knowledge is acquired. Recently in this journal Elizabeth Tropman has presented two arguments against this claim. In the present article, I attempt to show that the first argument attacks a straw man and the second mischaracterizes the Cornell realists' epistemology and ends up begging the question. I close by suggesting that, given Tropman's own apparent views, her objections are also probably misplaced.

It is often said that our moral experience, broadly construed to include our ways of thinking and talking about morality, has a certain objective-seeming character to it, and that this supports a presumption in favor of objectivist theories and against anti-objectivist theories like Mackie’s error theory. In this paper, I argue that our experience of morality does not support objectivist moral theories in this way. I begin by arguing that our moral experience does not have the uniformly objective-seeming character it (...) is typically claimed to have. I go on to argue that even if moral experience were to presuppose or display morality as a realm of fact, we would still need a reason for taking that to support theories according to which it is such a realm. I consider what I take to be the four most promising ways of attempting to supply such a reason: inference to the best explanation, epistemic conservatism, the Principle of Credulity, and the method of wide reflective equilibrium. In each case, I argue, the strategy in question does not support a presumption in favor of objectivist moral theories. (shrink)

I develop two different epistemic roles for emotion and desire. Caring for moral ends and people plays a pivotal though contingent role in ensuring reliable awareness of morally salient details; possession of various emotions and motives is a necessary condition for autonomous understanding of moral concepts themselves. Those who believe such connections compromise the "objective" status of morality tend to assume rather than argue for the bifurcated conception of reason and affect this essay challenges.

In the introduction to his Realism, mathematics and modality, and in earlier papers included in that collection, Hartry Field offered an epistemological challenge to platonism in the philosophy of mathematics. Justin Clarke-Doane Truth, objects, infinity: New perspectives on the philosophy of Paul Benacerraf, 2016) argues that Field’s challenge is an illusion: it does not pose a genuine problem for platonism. My aim is to show that Clarke-Doane’s argument relies on a misunderstanding of Field’s challenge.
