Different versions of moral projectivism are delineated: minimal, metaphysical, nihilistic, and noncognitivist. Minimal projectivism (the focus of this paper) is the conjunction of two subtheses: (1) that we experience morality as an objective aspect of the world and (2) that this experience has its origin in an affective attitude (e.g., an emotion) rather than in perceptual faculties. Both are empirical claims and must be tested as such. This paper does not offer ideas on any specific test procedures, but rather undertakes (...) the important preliminary task of clarifying the content of these subtheses (e.g., what is meant by "objective"? what is meant by "experience"?). Finally, attention is given to the relation between (a) acknowledging that the projectivist account might be true of a token moral judgment and (b) maintaining moral projectivism to be true as a general thesis.

Animal ethicists have been debating the morality of speciesism for over forty years. Despite rather persuasive arguments against this form of discrimination, many philosophers continue to assign humans a higher moral status than nonhuman animals. The primary source of evidence for this position is our intuition that humans’ interests matter more than the similar interests of other animals. And it must be acknowledged that this intuition is both powerful and widespread. But should we trust it for all that? The present (...) paper defends a negative answer to that question, based on a debunking argument. The intuitive belief that humans matter more than other animals is unjustified because it results from an epistemically defective process. It is largely shaped by tribalism, our tendency to favor ingroup members as opposed to outgroup members. And this influence is distortive for two reasons. First, tribalism evolved for reasons unrelated to moral truths; hence, it would at best produce true moral beliefs accidentally. Second, tribalism generates a vast quantity of false moral beliefs, starting with racist beliefs. Once this intuition is discarded, little evidence remains that speciesism is morally acceptable.

Many people believe that human interests matter much more than the like interests of non-human animals, and this “speciesist belief” plays a crucial role in the philosophical debate over the moral status of animals. In this paper, I develop a debunking argument against it. My contention is that this belief is unjustified because it is largely due to an off-track process: our attempt to reduce the cognitive dissonance generated by the “meat paradox”. Most meat-eaters believe that it is wrong to (...) harm animals unnecessarily, yet they routinely and deliberately behave in ways that cause great unnecessary suffering to animals. As recent research suggests, this practical inconsistency puts them in an unpleasant state of dissonance, which they try to escape by resolving the paradox. And they do so in part by adopting the speciesist belief—if animal suffering matters much less than human suffering, then harming animals cannot be so wrong after all. Since this belief-forming process does not track moral truth, I conclude that we are not justified in believing that human interests matter more than the similar interests of non-humans. (shrink)

According to pluralistic intuitionist theories, some of our moral beliefs are non-inferentially justified, and these beliefs come in both an a priori and an a posteriori variety. In this paper I present new support for this pluralistic form of intuitionism by examining the deeply social nature of moral inquiry. This is something that intuitionists have tended to neglect. It does play an important role in an intuitionist theory offered by Bengson, Cuneo, and Shafer-Landau (forth), but whilst they invoke the social (...) nature of moral inquiry in order to argue that ordinary moral intuitions are trustworthy, my argument focuses on what I will call the ‘frontiers’ of moral inquiry. I will show that inclusive and cooperative dialogue is necessary at moral inquiry’s frontiers, and that intuitionists can expect such dialogue to result in both a priori and a posteriori moral beliefs.

Moral abolitionists recommend that we get rid of moral discourse and moral judgement. At first glance this seems repugnant, but abolitionists think that we have overestimated the practical value of our moral framework and that eliminating it would be in our interests. I argue that abolitionism has a surprising amount going for it. Traditionally, abolitionism has been treated as an option available to moral error theorists. Error theorists say that moral discourse and judgement are committed to the existence of moral (...) properties, and that no such properties exist. After error theory is established, abolitionism is one potential way to proceed. However, many error theorists suggest that we retain moral discourse as a sort of fiction. I evaluate some attractions of both fictionalism and abolitionism, arguing that abolitionism is a plausible position. No one doubts that error theorists can be abolitionists. However, what has gone largely undiscussed is that it is open to others to be abolitionists as well. I argue that moral realists of a metaphysically robust sort can and perhaps should be abolitionists. ‘Realist abolitionism’ makes for a surprisingly neat theoretical package, and I conclude that it represents an interesting new option in the theoretical landscape.

The justificatory force of empirical reasoning always depends upon the existence of some synthetic, a priori justification. The reasoner must begin with justified, substantive constraints on both the prior probability of the conclusion and certain conditional probabilities; otherwise, all possible degrees of belief in the conclusion are left open given the premises. Such constraints cannot in general be empirically justified, on pain of infinite regress. Nor does subjective Bayesianism offer a way out for the empiricist. Despite often-cited convergence theorems, subjective (...) Bayesians cannot hold that any empirical hypothesis is ever objectively justified in the relevant sense. Rationalism is thus the only alternative to an implausible skepticism. (shrink)

Debunking skeptics claim that our moral beliefs are formed by processes unsuited to identifying objective facts, such as emotions inculcated by our genes and culture; therefore, they say, even if there are objective moral facts, we probably don’t know them. I argue that the debunking skeptics cannot explain the pervasive trend toward liberalization of values over human history, and that the best explanation is the realist’s: humanity is becoming increasingly liberal because liberalism is the objectively correct moral stance.

Many philosophers have argued that moral disagreement raises metaphysical and/or epistemological challenges for moral realism. In this paper, I consider whether widespread moral disagreement raises a different sort of challenge by threatening the semantic commitments of moral realism. In particular, I suggest that the character of many moral disagreements gives us reason to suspect that not all competent moral speakers pick out the same properties as one another when they use moral terms. If this is so, both sides of a (...) moral dispute may speak truly, and the standard realist diagnosis of such disputes—that at most one party can be correct—is mistaken. My argumentative strategy is to first isolate some features of linguistic exchanges that provide evidence of a lack of co-reference, and then argue that many moral disputes have these features. I conclude by suggesting that there are plausible accounts of moral disputes that do not require co-reference. (shrink)

I would like to thank Sonja Rinofner-Kreidl and Søren Overgaard for their penetrating and challenging criticisms of my book, Perception and Knowledge (henceforth ‘‘PK’’). What follows are responses to some, though by no means all, of the critical points each raises.

Hume seems to claim that there does not exist a valid argument that has all non-ethical sentences as premises and an ethical sentence as its conclusion. Starting with Prior, a number of counterexamples to this claim have been proposed. Unfortunately, all of these proposals are controversial. Even the most plausible have a premise that seems like it might be an ethical sentence or a conclusion that seems like it might be non-ethical. Since it is difficult to tell whether any of (...) these counterexamples are genuine, we need a taxonomy that sorts out ethical sentences from non-ethical ones. We need to know the difference between an ‘Is’ and an ‘Ought’. In the first part of the paper, I establish the need for a taxonomy. I consider some of the most influential ‘Is’–‘Ought’ derivations. These include proposals by Prior and Searle. I argue that each proposal has a premise whose status as ethical or non-ethical is difficult to determine. In the second part of the paper, I consider taxonomies proposed by Karmo and Maitzen. I argue against both taxonomies. I end with the claim that we need a taxonomy of ethical sentences and that none of the current proposals are adequate. (shrink)

Toomas Karmo claims that his taxonomy of ethical sentences has the result that there does not exist a sound argument with all non-ethical premises and an ethical conclusion. In a recent paper, Mark T. Nelson argues against this claim. Nelson presents a sound argument that he takes to be such that (i) Karmo’s taxonomy classifies that argument’s single premise as non-ethical and (ii) Karmo’s taxonomy classifies that argument’s conclusion as ethical. I attempt to show that Nelson is mistaken about (ii). (...) For any possible world at which the premise of Nelson’s argument is true, Karmo’s taxonomy classifies the conclusion of Nelson’s argument as non-ethical. (shrink)

If moral properties lacked causal powers, would moral skepticism be true? I argue that it would. Along the way I respond to various arguments that it would not.

This paper provides a novel critique of Walter Sinnott-Armstrong’s influential argument against epistemological moral intuitionism, the view that some people are non-inferentially justified in believing some moral propositions. At the beginning of the twenty-first century, this view experienced a revival, which coincided with an increasing interest in empirical research on intuitions. The results of that research are seen by some as casting serious doubt on the reliability of our moral intuitions. According to Sinnott-Armstrong, empirical evidence shows that our moral beliefs (...) have a high error rate in general, which creates a need for inferential confirmation for every single moral belief. His argument involves the problematic assumption that it is reasonable for informed moral believers to ascribe a high probability of error to every particular moral belief unless the believer has some special evidence that this particular moral belief belongs to a class that has a lower probability of error than the class of moral beliefs. Focussing on the non-moral example that Sinnott-Armstrong uses in the latest reformulation of his argument, the “Californian wine example”, I argue that apart from exceptional circumstances, the description of moral agents as ascribing correctness probabilities to their moral beliefs is odd, ERROR reveals an awkward picture of how agents relate to their moral beliefs and ERROR is problematic from the perspective of moral competence. This critique goes deeper than the worries raised by other critics to earlier versions of the argument, and part of it applies to moral intuitionism as well. (shrink)

It is a common idea that morality, or moral truths, if there are any, must have some sort of source, or grounding. It has also been claimed that constructivist theories in metaethics have an advantage over realist theories in that the former but not the latter can provide such a grounding. This paper has two goals. First, it attempts to show that constructivism does not in fact provide a complete grounding for morality, and so is on a par with realism (...) in this respect. Second, it explains why it seems that morality in fact couldn't have a source. (shrink)

It is widely held, even among nonnaturalists, that the moral supervenes on the natural. This is to say that for any two metaphysically possible worlds w and w′, and for any entities x in w and y in w′, any isomorphism between x and y that preserves the natural properties preserves the moral properties. In this paper, I put forward a conceivability argument against moral supervenience, assuming non-naturalism. First, I argue that though utilitarianism may be true, and the trolley driver (...) is permitted to kill the one to save the five, there is a conceivable scenario that is just like our world in all natural respects, yet at which deontology is true, and the trolly driver is not permitted to kill the one to save the five. I then argue that in the special case of morality, it is possible to infer from the conceivability of such a scenario to its possibility. It follows that supervenience is false. (shrink)

In this article, various objections will be discussed that have been put forward against ethical relativism, but which haven’t been considered seriously enough on the part of relativists and have been overrated on the part of their opponents. The objections will be concentrated into three arguments: the action-theoretic, the epistemological and the truth-theoretic argument. The article will discuss whether they can be rebutted by proponents of the two main types of relativism: indexical relativism and truth-relativism. The conclusion will be as (...) follows: one version of indexical relativism, the analytical version, gets into serious troubles by the action-theoretic argument, while its revisionary version will remain unaffected, the epistemological argument fails with respect to indexical relativism and stands on shaky ground as regards truth-relativism, the truth-theoretic argument puts considerable pressure on truth-relativism.

The argument from faultless disagreement against moral realism is based on the alleged possibility of cognitively faultless moral disagreement, CFD. This possibility contradicts the pre-theoretic intuition that moral truth is knowable, in principle, the so-called epistemic constraint on moral truth, EC. In this paper, I discuss the realist’s two options to cope with this argument. First of all, I point out the realist’s strategies to explain the possibility of cognitively faultless error, which is implied by CFD. Then I discuss one (...) promising option to respond to the argument from faultless disagreement: accepting both CFD and EC but blocking the ensuing contradiction by invoking an equivocation as regards the notion of knowability. After pointing out the drawbacks of this solution I discuss the other promising option: rejecting CFD by drawing on an agnostic stance on the part of cognitively blameless thinkers as regards moral propositions they cannot agree on. Yet this option faces the problem that EC has to be denied. In concluding the paper, I outline the prospects of an attractive objectivist shape of moral antirealism, which is also affected by the argument from faultless disagreement. (shrink)

This paper presents a moral argument in support of the view that the mind is a nonphysical object. It is intuitively obvious that we, the bearers of conscious experiences, have an inherent value that is not reducible to the value of our conscious experiences. It remains intuitively obvious that we have inherent value even when we represent ourselves to have no physical bodies whatsoever. Given certain assumptions about morality and moral intuitions, this implies that the bearers of conscious experiences—the objects (...) possessing inherent value—are not physical objects. This moral evidence is corroborated by introspective evidence. (shrink)

Benatar’s central argument for antinatalism develops an asymmetry between the pain and pleasure in a potential life. I am going to present an alternative route to the antinatalist conclusion. I argue that duties require victims and that as a result there is no duty to create the pleasures contained within a prospective life but a duty not to create any of its sufferings. My argument can supplement Benatar’s, but it also enjoys some advantages: it achieves a better fit with our (...) intuitions; it does not require us to acknowledge that life is a harm, or that a world devoid of life is a good thing; and it is easy to see why it does not have any pro-mortalist implications.

I’ll raise a problem for Retributivism, the view that legal punishment is justified on the basis of desert. I’ll focus primarily on Mitchell Berman’s recent defense of the view. He gives one of the most sophisticated and careful statements of it. And his argument is representative, so the problem I’ll raise for it will apply to other versions of Retributivism. His insights about justification also help to make the problem particularly obvious. I’ll also show how the problem extends to non-retributive (...) justifications of punishment. I’ll argue that Berman’s argument makes a questionable assumption about the standard of justification that justifications of punishment must meet to be successful. If we think about what it takes to justify punishment and reflect on the intuitions that retributivists appeal to, it turns out that the intuitions aren’t obviously up to the task. (shrink)

When libertarian political philosophy attracted wide public notice in the 1970s, a common view was that the distinctive individual rights advocated in libertarian theory required grounding in a theory of ethics. Recently, this view has come under challenge. It has been argued that resort to such grounding in ethical theory is unneeded. An appeal to common sense intuitions suffices to justify libertarianism. First, a brief account of libertarianism will be presented. Then, some examples of the older, pro-grounding position will be (...) discussed. Then, the principal defense of the newer view, Michael Huemer’s The Problem of Political Authority, will be examined. This discussion constitutes the substance of the present paper. The principal contention of the present article will be that the argument to libertarianism from intuitions does not succeed. In conclusion, it will be suggested that a return to the earlier, grounding view is indicated for philosophers who wish to defend libertarianism. (shrink)

Timothy O’Connor presents a novel and powerful version of the cosmological argument from contingency. What distinguishes his argument is that it does not depend on the Principle of Sufficient Reason. This version thus avoids powerful objections facing the Principle. We present and develop the argument, strengthening it in various ways. We fill in big gaps in the argument and answer criticisms. These include the criticisms that O’Connor considers as well as new criticisms. We explain how his replies to a Kantian (...) criticism and to the demand for contrastive explanation fail, and properly answer the criticism and the demand. We develop two new criticisms, the objection from opaqueness and the objection from constitution, and explain how these objections can be answered. (shrink)

In this paper I lay out, argue for, and defend ethical Mooreanism. In essence, the view says that some moral propositions are Moorean propositions and thus are epistemically superior to the conjunctions of the premises of skeptical arguments to the contrary. In Sect. 1 I explain Mooreanism and then ethical Mooreanism. In Sect. 2 I argue for ethical Mooreanism by noting a number of important epistemic parities that hold between certain moral truths and standard Moorean facts. In Sect. 3 I (...) defend ethical Mooreanism against the objection that moral propositions are too epistemically dissimilar to standard Moorean facts to count as Moorean truths. (shrink)

Ethical intuitionists regard moral knowledge as deriving from moral intuition, moral observation, moral emotion and inference. However, moral intuitions, observations and emotions are cultural artefacts which often differ starkly between cultures. Intuitionists attribute uncongenial moral intuitions, observations or emotions to bias or to intellectual or moral failings; but that leads to sectarian ad hominen attacks. Intuitionists try to avoid that by restricting epistemically genuine intuitions, observations or emotions to those which are widely agreed. That does not avoid the problem. It (...) also limits epistemically genuine intuitions, observations or emotions to those with meagre content, and the intuitionists offer no plausible explanation for how inference from such insubstantial propositions can engender substantial moral knowledge. Instead of moral knowledge, intuitionism offers the prospect of mutual name-calling between intellectually stagnant groups. I criticise and reject the principle of phenomenal conservatism, to which intuitionists sometimes appeal. (shrink)

A dogma of contemporary normative theorizing holds that some reasons are distinctively moral while others are not. Call this view Reasons Pluralism. This essay looks at four approaches to vindicating the apparent distinction between moral and non-moral reasons. In the end, however, all are found wanting. Though not dispositive, the failure of these approaches supplies strong evidence that the dogma of Reasons Pluralism is ill-founded.

Non-naturalists claim that the nature of normativity precludes the possibility of normative naturalism. In particular, they think that normative reduction amounts to normative elimination. This is because it always leaves out the normative. In this paper, I examine the force that the normativity objection has against Humean reductionism. I argue that the normativity objection has no argumentative force against reductionism. When it is presented as a bare intuition, it begs the question against reduction. A more interesting reading of the argument (...) claims that the normative cannot be explained in terms of the natural because the natural is arbitrary. Yet, this version of the argument fails as well because the natural is not arbitrary in the relevant sense. The natural is contingent, so what has value is contingent. That is not an elimination of the normative though, because contingent reasons are still reasons. (shrink)

Introduction: characterizing ethical realismIt is useful to begin a survey of recent work on ethical realism with a look at current disputes over what makes a theory of ethics count as ‘realist’ in the first place. Nearly all characterizations of ethical realism include some version of the following two core claims: Ethical discourse is assertoric and descriptive: ethical claims purport to state ethical facts by attributing ethical properties to people, actions, institutions, etc., and are thus true or false depending on (...) whether their descriptions of things are accurate or not . 1 At least some ethical claims, when literally construed, are true in the above sense.Sayre-McCord maintains that these two conditions are necessary and sufficient to characterize ethical realism; others argue that further conditions must be added to yield ethical realism, or at least ‘paradigmatic’ or ‘robust’ ethical realism. Before turning to that, however, it is worth noting that some have recently denied that the above two conditions are even necessary for ethical realism. In probing new work on metaethical taxonomy, Miller argues that the core of ethical realism is simply the metaphysical commitment to objective ethical properties and facts, which is strictly independent of the semantic claims above. If one holds that there are objective facts about the wrongness of slavery, for example, then one ought to count as an ethical realist regardless of whatever views one might hold about the semantics of the contingent forms of discourse that have evolved among language users. Even if our ethical discourse turns out primarily to express conative states ), or all moral claims turn out to be false because …. (shrink)

I begin by distinguishing two general approaches to metaethics and ontology. One in effect puts our experience as engaged ethical agents on hold while independent metaphysical and epistemological inquiries, operating by their own lights, deliver metaethical verdicts on acceptable interpretations of our ethical lives; the other instead keeps engaged ethical experience in focus and allows our reflective interpretation of it to shape our metaphysical and epistemological views, including our ontology. While the former approach often leads to deflationary views, the latter (...) may lead us to enrich our metaethical picture as needed to capture robust objectivity and categorical normative authority for ethics. Assuming, as I have argued elsewhere, that this requires positing irreducibly evaluative or normative properties and facts, the question I take up here is what ontological implications this has. I argue against quietist non-naturalist views, which maintain that positing such properties and facts either has no ontological implications or has only domain-specific ontological implications that likewise imply nothing about what the world contains. Against these views, I advocate a worldly, dual-aspect view, locating irreducibly evaluative or normative properties as features of relevant worldly things. But while I have previously defended this view as a form of non-naturalism, I here explore the possibility of instead seeing it as a new, more expansive form of naturalism—what might be called “Non-Scientistic Naturalism”—inspired by parallel attempts in the philosophy of mind to accommodate irreducibly phenomenal properties within a more expansive physicalism.

Suppose that disgust can provide evidence of moral wrongdoing. What account of disgust might make sense of this? A recent and promising theory is the social contagion view, proposed by Alexandra Plakias. After criticizing both its descriptive and normative claims, I draw two conclusions. First, we should question the wisdom of drawing so straight a line from biological poisons and pathogens to social counterparts. Second, we don’t need to explain the evidential value of disgust by appealing to what the response (...) tracks. These lessons point toward an alternative: namely, that disgust is a moral heuristic. On the heuristic view, disgust is a trigger for the subconscious use of a particular rule: I show how this view fits with a plausible hypothesis about the social function of disgust, and then apply it to Leon Kass’s famous use of repugnance to criticize cloning.

Survey of some recent literature on normativity, including nonreductionist, neo-Aristotelian, neo-Humean, expressivist, and constructivist views.

Farbod Akhlaghi (2021) argues that noncognitivists and naturalists cannot explain the epistemic possibility of wholesale moral error. This would show that noncognitivism and naturalism are false. I argue that noncognitivists and naturalists have no trouble explaining the epistemic possibility of wholesale moral error and that the requirement to explain this possibility is plausible only on one particular conception of epistemic possibility.

Metaethical—or, more generally, metanormative— realism faces a serious epistemological challenge. Realists owe us—very roughly speaking—an account of how it is that we can have epistemic access to the normative truths about which they are realists. This much is, it seems, uncontroversial among metaethicists, myself included. But this is as far as the agreement goes, for it is not clear—nor uncontroversial—how best to understand the challenge, what the best realist way of coping with it is, and how successful this attempt is. (...) In this paper I try, first, to present the challenge in its strongest version, and second, to show how realists—indeed, robust realists—can cope with it. The strongest version of the challenge is, I argue, that of explaining the correlation between our normative beliefs and the independent normative truths. And I suggest an evolutionary explanation as a way of solving it. (shrink)

In recent work, Bengson, Cuneo, and Shafer‐Landau (2020) develop a new social version of moral intuitionism that promises to explain why our moral intuitions are trustworthy. In this paper, we raise several worries for their account and present some general challenges for the broader class of views we call Social Moral Intuitionism. We close by reflecting on Bengson, Cuneo, and Shafer‐Landau's comparison between what they call the “perceptual practice” and the “moral intuition practice”, which we take to raise some difficult (...) normative and meta‐normative questions for theorists of all stripes.

I outline the debate in metaphysics between those who believe time is tensed and those who believe it is tenseless. I describe the terms in which this debate has been carried out, and the significance to it of ordinary tensed language and widespread common sense beliefs that time is tensed. I then outline a case for thinking that our intuitive beliefs about tense constitute an Adaptive Imaginary Representation (Wilson, in Biol Philos 5:37–62, 1990; Wilson, in Biol Philos 10:77–97, 1995). I (...) also outline a case for thinking that our ordinary tensed beliefs and tensed language owe their tensed nature to its being adaptive to adopt a temporally self-locating perspective on reality. If these conclusions are right, then common sense intuitions and temporal language will be utterly misleading guides to the nature of temporal reality. (shrink)

It seems that intuitions are indispensable in philosophical theorizing. Yet, there is evidence that our intuitions are heavily influenced by biases. This generates a puzzle: we must use our intuitions, but we seemingly cannot fully trust those very intuitions. In this paper, I develop a methodology for philosophical theorizing which attempts to avoid this puzzle. Specifically, I develop and defend a methodology that I call Extra-Wide Reflective Equilibrium. I argue that this method allows us to use intuitions, while also providing (...) a mechanism to check the influence of bias on our intuitions. In section I, defend the claim that intuitions are indispensable in philosophical theorizing. In section II, I outline recent arguments against the reliability of intuitions. In section III, I explain and defend my account of Extra-Wide Reflective Equilibrium. (shrink)

As the science and technology of the brain and mind develop, so do the ways in which brains and minds may be surveilled and manipulated. Some cognitive libertarians worry that these developments undermine cognitive liberty, or “freedom of thought.” I argue that protecting an individual’s cognitive liberty undermines others’ ability to use their own cognitive liberty. Given that the threatening devices and processes are not relevantly different from ordinary and frequent intrusions upon one’s brain and mind, strong protections of cognitive (...) liberty may proscribe neurotechnological intrusions, but also ordinary intrusions. Thus, the cognitive libertarian position “hog-ties” others’ use of their own liberties. This problem for the cognitive libertarian is the same problem that ordinary libertarianism faces in protecting individual rights to property and person. But the libertarian strategies for resolving the problem don’t work for the cognitive libertarian. I conclude that the right to mental privacy is weaker than what cognitive libertarians want it to be. (shrink)

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.

This paper concerns the epistemology of difficult moral cases where the difficulty is not traceable to ignorance about non-moral matters. The paper first argues for a principle concerning the epistemic status of moral beliefs about difficult moral cases. The basic idea behind the principle is that one’s belief about the moral status of a potential action in a difficult moral case is not justified unless one has some appreciation of what the relevant moral considerations are and how they bear on (...) the moral status of the potential action. The paper then argues that this principle has important ramifications for moral epistemology and moral metaphysics. It puts pressure on some views of the justification of moral belief, such as ethical intuitionism and reliabilism. It puts pressure on some antirealist views of moral metaphysics, including simple versions of relativism. It also provides some direct positive support for broadly realist views of morality.

Moral debunking arguments are meant to show that, by realist lights, moral beliefs are not explained by moral facts, which in turn is meant to show that they lack some significant counterfactual connection to the moral facts (e.g., safety, sensitivity, reliability). The dominant, “minimalist” response to the arguments—sometimes defended under the heading of “third-factors” or “pre-established harmonies”—involves affirming that moral beliefs enjoy the relevant counterfactual connection while granting that these beliefs are not explained by the moral facts. We show that (...) the minimalist gambit rests on a controversial thesis about epistemic priority: that explanatory concessions derive their epistemic import from what they reveal about counterfactual connections. We then challenge this epistemic priority thesis, which undermines the minimalist response to debunking arguments (in ethics and elsewhere). (shrink)

One of the most important disputes in the foundations of ethics concerns the source of practical reasons. On the desire-based view, only one’s desires provide one with reasons to act. On the value-based view, reasons are instead provided by the objective evaluative facts, and never by our desires. Similarly, there are desire-based and non-desired-based theories about two other phenomena: pleasure and welfare. It has been argued, and is natural to think, that holding a desire-based theory about either pleasure or welfare (...) commits one to recognizing that desires do provide reasons for action – i.e., commits one to abandoning the value-based theory of reasons. The purpose of this paper is to show that this is not so. All of the following can be true: pleasure and welfare provide reasons; pleasure and welfare are to be understood in terms of desire; desires never provide reasons, in the relevant way. (shrink)

This paper critically examines coincidence arguments and evolutionary debunking arguments against non-naturalist realism in metaethics. It advances a version of these arguments that goes roughly like this: Given a non-naturalist, realist metaethic, it would be cosmically coincidental if our first order normative beliefs were true. This coincidence undermines any prima facie justification enjoyed by those beliefs.

Are there such things as moral truths? How do we know what we should do? And does it matter? Constructivism states that moral truths are neither invented nor discovered, but rather are constructed by rational agents in order to solve practical problems. While constructivism has become the focus of many philosophical debates in normative ethics, meta-ethics and action theory, its importance is still to be fully appreciated. These new essays written by leading scholars define and assess this new approach in (...) ethics, addressing such questions as the nature of constructivism, how constructivism improves our understanding of moral obligations, how it accounts for the development of normative practices, whether moral truths change over time, and many other topics. The volume will be valuable for advanced students and scholars of ethics and all who are interested in questions about the foundation of morality. (shrink)

Aesthetic non-naturalism is the view that there are objective aesthetic truths that hold in virtue of sui generis facts. This view is seldom explicitly endorsed in philosophical aesthetics. I argue that many aestheticians should treat it as the view to beat, since (a) their commitments favour aesthetic realism, (b) non-naturalistic forms of aesthetic realism are particularly promising and (c) non-naturalists have reasonable answers to four important objections.

Debunking arguments use empirical evidence about our moral beliefs - in particular, about their causal origins, or about how they depend on various causes - in order to reach an epistemic conclusion about the trustworthiness of such beliefs. In this thesis, I investigate the scope and limits of debunking arguments, and their implications for what we should believe about morality. I argue that debunking arguments can in principle work - they are based on plausible epistemic premises, and at least some (...) of them avoid putative problems concerning regress and redundancy. However, I also argue that some debunking arguments fall short because they are insufficiently supported by the empirical evidence. By considering different objections, analyses, and a case study, I explore the conditions for a successful debunking argument. (shrink)

Evolutionary debunking arguments abound, but it is widely assumed that they do not arise for our perceptual beliefs about midsized objects, insofar as the adaptive value of our object beliefs cannot be explained without reference to the objects themselves. I argue that this is a mistake. Just as with moral beliefs, the adaptive value of our object beliefs can be explained without assuming that the beliefs are accurate. I then explore the prospects for other sorts of vindications of our object (...) beliefs—which involve “bootstrapping” from our experiences as of midsized objects—and I defend bootstrapping maneuvers against a variety of objections. Finally, I argue for an explanatory constraint on legitimate bootstrapping and show how some attempts to respond to debunking arguments run afoul of the constraint. (shrink)

This thesis motivates a novel account of desire as the best explanation of an intuitive datum. The intuitive datum is that often when an agent desires P she will immediately, outright know that she has a reason to bring P about. Existing explanations of the intuitive datum cannot simultaneously satisfy two desiderata. We want to explain how desires enable outright knowledge of reasons and also explain the fallibility of desires. Existing views satisfy the first desideratum at the expense of the (...) second, or vice versa. I propose an epistemological disjunctivist account of desire that satisfies both. On this view, a desire for P represents the value of P in a manner analogous to perception. Desires come in two distinct epistemic kinds: an awareness of value or an illusion of value. An awareness of value enables outright knowledge of reasons and allows the agent to tell by reflection that she has such knowledge. An illusion of value merely seems to provide grounds for knowledge, which explains the fallibility of desires. The proposed account is a strong candidate for the truth because it best explains central features of our practical agency. (shrink)
