Evolutionary debunking arguments move from a premise about the influence of evolutionary forces on our moral beliefs to a skeptical conclusion about those beliefs. My primary aim is to clarify this empirically grounded epistemological challenge. I begin by distinguishing among importantly different sorts of epistemological attacks. I then demonstrate that instances of each appear in the literature under the ‘evolutionary debunking’ title. Distinguishing them clears up some confusions and helps us better understand the structure and potential of evolutionary debunking arguments.

Manuel Vargas advocates a revised understanding of the terms “free will” and “moral responsibility” that eliminates the problematic libertarian commitments inherent to the commonsense understanding of these terms. I argue that in order to make a plausible case for why philosophers ought to adopt his recommendations, Vargas must explain why we ought to retain the retributivist elements that figure prominently in both commonsense views about morality and philosophical discussions concerning free will and moral responsibility. Furthermore, I argue that his revisionist (...) account lacks the resources necessary to accommodate retributivist attitudes and practices. (shrink)

Are values objective or subjective? To clarify this question we start with an overview of the main concepts and debates in the philosophy of values. We then discuss the arguments for and against value realism, the thesis that there are objective evaluative facts. By contrast with value anti-realism, which is generally associated with sentimentalism, according to which evaluative judgements are grounded in sentiments, value realism is commonly coupled with rationalism. Against this common view, we argue that value realism can be (...) combined with sentimentalism, and we suggest that a plausible account, which we call ‘sentimental realism’, and according to which evaluative judgements are closely related to emotions, can be developped.

The fact of moral disagreement when conjoined with Conciliationism, an independently attractive view about the epistemic significance disagreement, seems to entail moral skepticism. This worries those who like Conciliationism, the independently attractive view, but dislike moral skepticism. Others, equally inclined against moral skepticism, think this is a reductio of Conciliationism. I argue that they are both wrong. There is no reductio and nothing to worry about.

Metaethical absolutism is the view that moral concepts have non-relative satisfaction conditions that are constant across judges and their particular beliefs, attitudes, and cultural embedding. If it is correct, there is an important sense in which parties of moral disputes are concerned to get the same things right, such that their disputes can be settled by the facts. If it is not correct, as various forms of relativism and non-cognitivism imply, such coordination of concerns will be limited. The most influential (...) support for absolutism comes from an argument with two related premises. According to the first premise, moral thinking and moral discourse display a number of features that are characteristically found in paradigmatically absolutist domains, and only partly in uncontroversially non-absolutist domains. According to the second, the best way of making sense of these features is to assume that absolutism is correct. This paper defends the prospect of a non-ad hoc, non-absolutist, explanation of these "absolutist" features, thus calling into question the second premise. But instead of attempting to directly explain why the moral domain displays these features, it attends to how they are partially displayed by paradigmatically non-absolutists judgments about taste and likelihood. Based on this, it proposes independently motivated general accounts of attributions of agreement, disagreement, correctness and incorrectness that can explain both why absolutist domains display all "absolutist" features and why these non-absolutist domains display some. Based on these accounts, it provides preliminary reasons to think that these features of moral discourse can be given a non-absolutist explanation. (shrink)

L’objectif de cette article est de comprendre la neutralité axiologique non pas comme une exigence épistémologique, mais plutôt comme un idéal éducationnel. Max Weber propose une science basée sur la description factuelle, de laquelle on exclut la formulation de jugements de valeur. Or, il faut démontrer pourquoi il est préférable de séparer les jugements descriptifs des jugements évaluatifs. L’objectif de Weber est de préserver l'autonomie intellectuelle des étudiants. Pour Weber, la classe et l'académie en général sont des lieux politiques. Ces (...) rapports au sein de la classe sont nécessaires pour transmettre des connaissances, des méthodes et le goût de l'autonomie intellectuelle. Or, il serait contraire au principe d'autonomie de laisser le professeur influencer et convaincre ses étudiants, de façon partisane, d'adhérer à certaines thèses normatives. Weber propose ainsi un mécanisme pour éviter que le professeur n'ixnfluence ses étudiants de manière illégitime. (shrink)

Foundations for Moral Relativism consists of five self-standing, though loosely related, essays on the nature of agency and its metaethical foundations. The essays do not aspire to offer any grand theory of agency or metaethics, but only to lay out some of the foundations for such theories. These foundations portray how agency in general is constructed in the social context of a community, how moral agency in particular is constructed in the social context of a community, and how a derivative (...) relativist account of morality can be not only intellectually respectable but also plausible. In paving the way for moral relativism, Velleman clarifies popular confusions about relativism, responds to a number of traditional objections and sketches a sophisticated version of moral relativism that is meant to improve on more simplistic versions.There is much to praise in these thought provoking essays and they are highly recommended to anyone working on agency and metaethics. They are lucid, succi .. (shrink)

In an influential book, Gilbert Harman writes, "In explaining the observations that support a physical theory, scientists typically appeal to mathematical principles. On the other hand, one never seems to need to appeal in this way to moral principles [1977, 9 – 10]." What is the epistemological relevance of this contrast, if genuine? In this article, I argue that ethicists and philosophers of mathematics have misunderstood it. They have confused what I will call the justificatory challenge for realism about an (...) area, D – the challenge to justify our D-beliefs – with the reliability challenge for D-realism – the challenge to explain the reliability of our D-beliefs. Harman’s contrast is relevant to the first, but not, evidently, to the second. One upshot of the discussion is that genealogical debunking arguments are fallacious. Another is that indispensability considerations cannot answer the Benacerraf-Field epistemological challenge for mathematical realism. (shrink)

Recent work in the psychology of happiness has led some to conclude that we are unreliable assessors of our lives and that skepticism about whether we are happy is a genuine possibility worth taking very seriously. I argue that such claims, if true, have worrisome implications for procreation. In particular, they show that skepticism about whether many if not most people are well positioned to create persons is a genuine possibility worth taking very seriously. This skeptical worry should not be (...) confused with a related but much stronger version of the argument, which says that all human lives are very bad and not worth starting. I criticize the latter stance, but take seriously the former stance and hope it can be answered in future work. (shrink)

Both realist and anti-realist accounts of natural kinds possess prima facie virtues: realists can straightforwardly make sense of the apparent objectivity of the natural kinds, and anti-realists, their knowability. This paper formulates a properly anti-realist account designed to capture both merits. In particular, it recommends understanding natural kinds as ‘categorical bottlenecks,’ those categories that not only best serve us, with our idiosyncratic aims and cognitive capacities, but also those of a wide range of alternative agents. By endorsing an ultimately subjective (...) categorical principle, this view sidesteps epistemological difficulties facing realist views. Yet, it nevertheless identifies natural kinds that are fairly, though not completely, stance-independent or objective. (shrink)

Creatures inveterately wrong in their inductions have a pathetic but praiseworthy tendency to die before reproducing their kind.- Quine (1969)We think that some facts - for example, the fact that someone is suffering, or the fact that all previously encountered tigers were carnivorous – supply us with normative reasons for action and belief. The former fact, we think, is a reason to help the suffering person; the latter fact is a reason to believe that the next tiger we see will (...) also be carnivorous. But how is the reason-giving status of such facts best understood? In particular, is it best understood as ultimately “conferred” upon these facts by our own evaluative attitudes, or do at least some facts possess normative reason-giving status in a way that is robustly independent of our attitudes? This is the modern, secular version of Plato's “Euthyphro question” - couched here in the philosophically useful, though not essential, language of normative reasons. (shrink)

What implications, if any, does evolutionary biology have for metaethics? Many believe that our evolutionary background supports a deflationary metaethics, providing a basis at least for debunking ethical realism. Some arguments for this conclusion appeal to claims about the etiology of the mental capacities we employ in ethical judgment, while others appeal to the etiology of the content of our moral beliefs. In both cases the debunkers’ claim is that the causal roles played by evolutionary factors raise deep epistemic problems (...) for realism: if ethical truths are objective or independent of our evaluative attitudes, as realists maintain, then we lose our justification for our ethical beliefs once we become aware of the evolutionary shaping of our ethical capacities or beliefs, which would not have disposed us reliably to track independent ethical truths; realism, they claim, thus saddles us with ethical skepticism. I distinguish and spell out various evolutionary debunking arguments along these lines and argue that they all fail: the capacity etiology argument fails to raise any special or serious problem for realism, and the content etiology arguments all rely on strong explanatory claims about our moral beliefs that are simply not supported by the science unless it is supplemented by philosophical claims that just beg the question against realism from the start. While the various debunking arguments do bring out some interesting commitments of ethical realism, and even raise some good challenges as realists develop positive moral epistemologies, they fall far short of their debunking ambitions.

Our project in this essay is to showcase nonnaturalistic moral realism’s resources for responding to metaphysical and epistemological objections by taking the view in some new directions. The central thesis we will argue for is that there is a battery of substantive moral propositions that are also nonnaturalistic conceptual truths. We call these propositions the moral fixed points. We will argue that they must find a place in any system of moral norms that applies to beings like us, in worlds (...) similar to our own. By committing themselves to true propositions of these sorts, nonnaturalists can fashion a view that is highly attractive in its own right, and resistant to the most prominent objections that have been pressed against it.

One of the alleged advantages of a constructivist theory in metaethics is that the theory avoids the epistemological problems with moral realism while reaping many of realism's benefits. According to evolutionary debunking arguments, the epistemological problem with moral realism is that the evolutionary history of our moral beliefs makes it hard to see how our moral beliefs count as knowledge of moral facts, realistically construed. Certain forms of constructivism are supposed to be immune to this argument, giving the view a (...) key advantage. This paper considers the challenge that evolutionary debunking arguments pose for the possibility of moral knowledge and concludes that such arguments do not reveal any advantages for constructivism. Furthermore, once we consider how defenders of moral knowledge should best respond to this epistemological objection, constructivists may face more difficulties, not less, explaining how our moral beliefs represent moral knowledge.

In recent years, William Lane Craig has vigorously championed a moral argument for God's existence. The backbone of Craig's argument is the claim that only God can provide a ' sound foundation in reality' for morality. The present article has three principal aims. The first is to interpret and clarify the account of the ontological foundation of morality proposed by Craig. The second is to press home an important objection to that account. The third is to expose the weakness of (...) Craig's case for saying that without God morality would be groundless and illusory. (shrink)

Argues that there are two distinct senses in which knowledge is incompatible with accidental truth - each of which can be traced to a distinct role played by everyday knowledge attributions.

Suppose we grant that evolutionary forces have had a profound effect on the contours of our normative judgments and intuitions. Can we conclude anything from this about the correct metaethical theory? I argue that, for the most part, we cannot. Focusing my attention on Sharon Street’s justly famous argument that the evolutionary origins of our normative judgments and intuitions cause insuperable epistemological difficulties for a metaethical view she calls "normative realism," I argue that there are two largely independent lines of (...) argument in Street’s work which need to be teased apart. The first of these involves a genuine appeal to evolutionary considerations, but it can fairly easily be met by her opponents. The second line of argument is more troubling; it raises a significant problem, one of the most difficult in all of philosophy, namely how to justify our reliance on our most basic cognitive faculties without relying on those same faculties in a question-begging manner. However, evolutionary considerations add little to this old problem, and rejecting normative realism is not a way to solve it. (shrink)

Does evolutionary theory have the potential to undermine morality? In his book The Evolution of Morality, Richard Joyce (2006) argues for a positive answer. He contends that an evolutionary account of morality would undermine moral judgements and lend support to moral scepticism. I offer a critique of Joyce’s argument. As it turns out, his case can be read in two different ways. It could be construed as an argument to establish a general scepticism about the justification of moral judgements. Or (...) it could be read as an argument that targets only a particular meta-ethical position, namely moral realism. My claim is that it fails on both interpretations. There is no reason to believe that evolutionary considerations undermine morality. (shrink)

The causal nominalist theory of properties appears at first glance to offer a novel nominalist approach and one that can provide an illuminating response to the one over many problem. I argue, however, that on closer inspection causal ‘nominalism’ collapses into either a version of realism or a mere variant of one of the traditional nominalist approaches. In the case of Whittle’s specific brand of causal nominalism, I suggest it is best thought of as a version of what Armstrong calls (...) ‘ostrich’ nominalism, a view which ultimately refuses to acknowledge the one over many problem rather than provide a solution to it.

In this paper I defend what I call the argument from epistemic reasons against the moral error theory. I argue that the moral error theory entails that there are no epistemic reasons for belief and that this is bad news for the moral error theory since, if there are no epistemic reasons for belief, no one knows anything. If no one knows anything, then no one knows that there is thought when they are thinking, and no one knows that they (...) do not know everything. And it could not be the case that we do not know that there is thought when we believe that there is thought and that we do not know that we do not know everything. I address several objections to the claim that the moral error theory entails that there are no epistemic reasons for belief. It might seem that arguing against the error theory on the grounds that it entails that no one knows anything is just providing a Moorean argument against the moral error theory. I show that even if my argument against the error theory is indeed a Moorean one, it avoids Streumer's, McPherson's and Olson's objections to previous Moorean arguments against the error theory and is a more powerful argument against the error theory than Moore's argument against external world skepticism is against external world skepticism.

This paper provides a discussion of the role that emotions may play in the justification of punishment. On the expressivist account of punishment, punishment has the purpose of expressing appropriate emotional reactions to wrongdoing, such as indignation, resentment or guilt. I will argue that this expressivist approach fails as these emotions can be expressed other than through the infliction of punishment. Another argument for hard treatment put forward by expressivists states that punitive sanctions are necessary in order for the law (...) to be valid. But this justification of punishment, too, is unconvincing. There are no good reasons to assume that we have to resort to punitive measures in order to vindicate the law. I will then raise the more general worry whether there is any intelligible link at all between moral emotions such as indignation, resentment or guilt and retributive behaviour. I will finally conclude with some sceptical remarks on the moral worth of retribution. (shrink)

This entry addresses the nature and epistemological role of intuition by considering the following questions: (1) What are intuitions?, (2) What roles do they serve in philosophical (and other “armchair”) inquiry?, (3) Ought they serve such roles?, (4) What are the implications of the empirical investigation of intuitions for their proper roles?, and (5) What is the content of intuitions prompted by the consideration of hypothetical cases?

Evolutionary accounts of the origins of human morality may lead us to doubt the truth of our moral judgments. Sidgwick tried to vindicate ethics from this kind of external attack. However, he ended The Methods in despair over another problem—an apparent conflict between rational egoism and universal benevolence, which he called the “dualism of practical reason.” Drawing on Sidgwick, we show that one way of defending objectivity in ethics against Sharon Street’s recent evolutionary critique also puts us in a position (...) to support a bold claim: the dualism of practical reason can be resolved in favor of impartiality.

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)

Call the ethos understanding rightness in terms of spiritual purity and piety, and wrongness in terms of corruption and sacrilege, the “fetish ethic.” Jonathan Haidt and his colleagues suggest that this ethos is particularly salient to political conservatives and non-liberal cultures around the globe. In this essay, I point to numerous examples of moral fetishism in mainstream academic ethics. Once we see how deeply “infected” our ethical reasoning is by fetishistic intuitions, we can respond by 1) repudiating the fetishistic impulse, (...) by 2) “sublimating” our fetishism into liberal rationales, or by 3) accepting the fetishism on its own terms. Of these options, I argue that sublimating our fetishism is not advisable, and that embracing our ethical fetishism isn’t as obviously misguided as some suggest. (shrink)

A prominent argument for moral realism notes that we are inclined to accept realism in science because scientific inquiry supports a robust set of critical practices—error, improvement, explanation, and the like. It then argues that because morality displays a comparable set of critical practices, a claim to moral realism is just as warranted as a claim to scientific realism. But the argument is only as strong as its central analogy—and here there is trouble. If the analogy between the critical practices (...) of science and morality is loosely interpreted, the argument does not support moral realism—for paradigmatically constructivist discourses like fashion display the relevant critical practices just as well. So if the argument is to have force, the realist must say more about why the critical practices of morality are sufficiently like those of science to warrant realism. But this cannot be done—moral inquiry differs from scientific inquiry in too many important ways. So the analogy with the critical practices of science fails to vindicate moral realism. But there are further lessons: in looking closely at the critical practices of our moral discourse—and in comparing them to the critical practices of science and fashion—we gain insight into what is distinctive about morality objectivity and moral metaphysics.

This dissertation is a critique of synthetic ethical naturalism (SEN). SEN is a view in metaethics that comprises three key theses: first, there are moral properties and facts that are independent of the beliefs and attitudes of moral appraisers (moral realism); second, moral properties and facts are identical to (or constituted only by) natural properties and facts (ethical naturalism); and third, sentences used to assert identity or constitution relations between moral and natural properties are expressions of synthetic, a posteriori necessities. (...) The last of these theses, which distinguishes SEN from other forms of ethical naturalism, is supported by a fourth: the semantic contents of the central moral predicates such as 'morally right' and 'morally good' are fixed in part by features external to the minds of speakers (moral semantic externalism). Chapter 1 introduces SEN and discusses the most common motivations for accepting it. The next three chapters discuss the influential "Moral Twin Earth" argument against moral semantic externalism. In Chapter 2, I defend this argument from the charge that the thought experiment upon which it depends is defective. In Chapters 3 and 4, I consider two attempts to amend SEN so as to render it immune to the Moral Twin Earth argument. I show that each of these proposed amendments amounts to an abandonment of SEN. Chapter Five explores Richard Boyd's proposal that moral goodness is a "homeostatic property cluster." If true, Boyd's hypothesis could be used to support several metaphysical, epistemological, and semantic claims made on behalf of SEN. I advance three arguments against this account of moral goodness. In the sixth chapter, I argue that moral facts are not needed in the best a posteriori explanations of our moral beliefs and moral sensibility. Because of this, those who accept a metaphysical naturalism ought to deny the existence of such facts or else accept skepticism about moral knowledge. In Chapter 7, I consider a counterargument on behalf of SEN to the effect that moral facts are needed in order to explain the predictive success of our best moral theories. I show that this argument fails. (shrink)

This paper applies the theory of teleosemantics to the issue of moral content. Two versions of teleosemantics are distinguished: input-based and output-based. It is argued that applying either to the case of moral judgements generates the conclusion that such judgements have both descriptive (belief-like) and directive (desire-like) content, intimately entwined. This conclusion directly validates neither descriptivism nor expressivism, but the application of teleosemantics to moral content does leave the descriptivist with explanatory challenges which the expressivist does not face. Since teleosemantics (...) ties content to function, the paper also offers an account of the evolutionary function of moral judgements. (shrink)

Abstract Street has argued that the meta-ethical realist is faced with a dilemma. Either evolutionary forces have had a distorting influenced on our ability to track moral properties or evolutionary forces influenced our beliefs in the direction of tracking moral properties. Street argues that if the realist accepts the first horn of the dilemma, the realist must accept implausible skepticism regarding moral beliefs. If the realist accepts the second horn of the dilemma, the realist owes an explanation of the fitness (...) producing nature of moral beliefs. As Street establishes the dialectic, the anti-realist’s explanation is better. I will argue that Street’s first horn is question begging then I will grasp the second horn of the dilemma and argue that only the realist can explain the role of moral beliefs in our evolutionary history. My argument will take the form of a dilemma. For our evaluative judgments to be fitness conducive, they must be responsive to the right sort of external world properties. The non-reductive realist can provide such a set of properties. On the first horn of the dilemma, the anti-realist cannot. The realist, unlike the anti-realist, can explain why our evaluative judgments are fitness conducive. The realist has won the explanatory battle. On the second horn of the dilemma, the anti-realist can provide a set of non-normative external world properties that our evaluative attitudes are responsive to. In doing so, the anti-realist has provided the heretofore-missing component of the reductive realist’s project. Again, the realist has won. (shrink)

In "Mathematical Truth", Paul Benacerraf articulated an epistemological problem for mathematical realism. His formulation of the problem relied on a causal theory of knowledge which is now widely rejected. But it is generally agreed that Benacerraf was onto a genuine problem for mathematical realism nevertheless. Hartry Field describes it as the problem of explaining the reliability of our mathematical beliefs, realistically construed. In this paper, I argue that the Benacerraf Problem cannot be made out. There simply is no intelligible problem (...) that satisfies all of the constraints which have been placed on the Benacerraf Problem. The point generalizes to all arguments with the structure of the Benacerraf Problem aimed at realism about a domain meeting certain conditions. Such arguments include so-called "Evolutionary Debunking Arguments" aimed at moral realism. I conclude with some suggestions about the relationship between the Benacerraf Problem and the Gettier Problem. (shrink)

Adaptationist accounts of morality attempt to explain the evolution of morality in terms of the selective advantage that judging in moral terms secured for our ancestors (e.g. Ruse 1998; Joyce 2006; Street 2006). So-called by-product explanations of morality have been presented as an alternative to adaptationist accounts (e.g. Prinz 2009; Ayala 2010; cf. Darwin 2004/1871). In assessing the relationship between adaptationist and by-product accounts, care must be taken to distinguish several related but importantly different notions: innateness, adaptation, exaptation, spandrel, and (...) by-product.

Constructivism in ethics is the view that insofar as there are normative truths, for example, truths about what we ought to do, they are in some sense determined by an idealized process of rational deliberation, choice, or agreement. As a “first-order moral account”--an account of which moral principles are correct-- constructivism is the view that the moral principles we ought to accept or follow are the ones that agents would agree to or endorse were they to engage in a hypothetical (...) or idealized process of rational deliberation. As a “metaethical account” – an account of whether there are any normative truths and, if so, what they are like – constructivism holds that there are normative truths. These truths are not fixed by facts that are independent of the practical standpoint, however characterized; rather, they are constituted by what agents would agree to under some specified conditions of choice. In working to provide a more precise definition of constructivism in metaethics, the focus of this entry, one faces two main difficulties. The first difficulty is that constructivism comes in several varieties, each of which claims a different niche within metaethics, and some claim no space at all. The second difficulty concerns where to place constructivism on the metaethical map in relation to realism and anti-realism. These are terms of art, and it is highly contested which views count as realist and which as antirealist. These two difficulties will be addressed in what follows by focusing on the distinctive questions that constructivist theories are designed to answer. Section §1 defines the scope of constructivism in ethics, in contrast to constructivism in political theory. Sections §§2-5 illustrate the main varieties of metaethical constructivism, which are designed to account for the nature of normative truths and practical reasons. Section §6 presents the main varieties of constructivist accounts of the justification of moral judgments of right and wrong. Section §7 discusses the metaethical status of constructivism, and its distinctive import. (shrink)

Intuitions are widely assumed to play an important evidential role in ethical inquiry. In this paper I critically discuss a recently influential claim that the epistemological credentials of ethical intuitions are undermined by their causal pedigree and functional role. I argue that this claim is exaggerated. In the course of doing so I argue that the challenge to ethical intuitions embodied in this claim should be understood not only as a narrowly epistemological challenge, but also as a substantially ethical one. (...) I argue that this fact illuminates the epistemology of ethical intuitions. (shrink)

I believe that Tom is the proud father of a baby boy. Why do I think his child is a boy? A natural answer might be that I remember that his name is ‘Owen’ which is usually a boy’s name. Here I’ve given information that might be part of a causal explanation of my believing that Tom’s baby is a boy. I do have such a memory and it is largely what sustains my conviction. But I haven’t given you just (...) any causally relevant information, I’ve given my grounds for my belief. I’ve given reasons that might justify me in supposing that Tom’s baby is a boy. Less naturally, the question might be taken as a request for a broader causal explanation of my holding this belief. Appropriate answers might cite all manner of facts concerning the evolution of the human race, why I chose to pursue philosophy and hence came to know Tom, the mechanisms of email transmission, the firing of various neurons, the circumstances of concept formation as a result of which I’m able to grasp the thought that Tom’s baby is a boy, and so on. It is an interesting question what distinguishes the narrower set of answers that I first suggested. I won’t pursue that here. I assume you have a good enough sense of the distinction I’m drawing. We might call the narrower set of answers justifying reasons, the kind of reasons I might cite in justifying my belief. Answers of the first sort are clearly relevant to epistemological evaluation. In assessing whether you know p or are rational in believing it to the degree you do, I will naturally want to consider what reasons you have for your belief. In deliberating myself about whether to believe p, in seeking an answer to the question of whether p, I will naturally consider what reasons or grounds I have to suppose that p. But what I want to focus on here is how explanations of the broader sort bear on such questions as whether to believe p. From a third-person perspective we can ask, ‘In assessing the epistemic status of S’s belief that p, what is the relevance of causal information that lies outside of the realm of justifying reasons?’ From the first-person standpoint we can ask ‘In seeking to answer whether p, how should such causal information affect my deliberations?’ At first it might seem that such broader causal information could have little relevance if any. Like any belief my belief that p can be traced back to innumerable causes from far and wide.. (shrink)

According to some recent arguments, if our moral beliefs are products of natural selection, then we do not have moral knowledge. In defense of this inference, its proponents argue that natural selection is a process that fails to track moral facts. In this paper, I argue that our having moral knowledge is consistent with, the hypothesis that our moral beliefs are products of natural selection, and the claim that natural selection fails to track moral facts. I also argue that natural (...) selection is a process that could track moral facts, albeit imperfectly. I do not argue that we do have moral knowledge. I argue instead that Darwinian considerations provide us with no reason to doubt that we do, and with some reasons to suppose that we might. (shrink)

We think of logic as objective. We also think that we are reliable about logic. These views jointly generate a puzzle: How is it that we are reliable about logic? How is it that our logical beliefs match an objective domain of logical fact? This is an instance of a more general challenge to explain our reliability about a priori domains. In this paper, I argue that the nature of this challenge has not been properly understood. I explicate the challenge (...) both in general and for the particular case of logic. I also argue that two seemingly attractive responses – appealing to a faculty of rational insight or to the nature of concept possession – are incapable of answering the challenge. (shrink)

The Principle of Sufficient Reason is a powerful and controversial philosophical principle stipulating that everything must have a reason or cause. This simple demand for thoroughgoing intelligibility yields some of the boldest and most challenging theses in the history of metaphysics and epistemology. In this entry we begin with explaining the Principle, and then turn to the history of the debates around it. A section on recent discussions of the Principle will be added in the near future.

The “ ethics of belief” refers to a cluster of questions at the intersection of epistemology, philosophy of mind, psychology, and ethics. The central question in the debate is whether there are norms of some sort governing our habits of belief formation, belief maintenance, and belief relinquishment. Is it ever or always morally wrong to hold a belief on insufficient evidence? Is it ever or always morally right to believe on the basis of sufficient evidence, or to withhold belief in (...) the perceived absence of it? Is it ever or always obligatory to seek out all available epistemic evidence for a belief? Are there some ways of obtaining evidence that are themselves immoral or imprudent? -/-. (shrink)

Most agree that when it comes to so-called 'first-order' normative ethics and political philosophy, constructivist views are a powerful family of positions. When it comes to metaethics, however, there is serious disagreement about what, if anything, constructivism has to contribute. In this paper I argue that constructivist views in ethics include not just a family of substantive normative positions, but also a distinct and highly attractive metaethical view. I argue that the widely accepted 'proceduralist characterization' of constructivism in ethics is (...) inadequate, and I propose what I call the 'practical standpoint characterization' in its place. I then offer a general taxonomy of constructivist positions in ethics. Since constructivism's standing as a family of substantive normative positions is relatively uncontested, I devote the remainder of the paper to addressing skeptics' worries about the distinctiveness of constructivism understood as a metaethical view. I compare and contrast constructivism with three other standard metaethical positions with which it is often confused or mistakenly thought to be compatible: realism; naturalist reductions in terms of an ideal response; and expressivism. In discussing the contrast with expressivism, I explain the sense in which, according to the constructivist, the distinction between substantive normative ethics and metaethics breaks down. I conclude by distinguishing between two importantly different debates about the mind-dependence of value. I argue that a failure to make this distinction is part of what explains why the possibility of constructivism as a metaethical view is often overlooked. (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.

This paper defends moral realism against Sharon Street’s “Darwinian Dilemma for Realist Theories of Value” (this journal, 2006). I argue by separation of cases: From the assumption that a certain normative claim is true, I argue that the first horn of the dilemma is tenable for realists. Then, from the assumption that the same normative claim is false, I argue that the second horn is tenable. Either way, then, the Darwinian dilemma does not add anything to realists’ epistemic worries.

It has been claimed that the recent wave of neuroscientific research into the physiological underpinnings of our moral intuitions has normative implications. In particular, it has been claimed that this research discredits our deontological intuitions about cases, without discrediting our consequentialist intuitions about cases. In this paper I demur. I argue that such attempts to extract normative conclusions from neuroscientific research face a fundamental dilemma: either they focus on the emotional or evolved nature of the psychological processes underlying deontological intuitions, (...) in which case the arguments rely on a blatantly fallacious inference, or they appeal to the (alleged) moral irrelevance of the factors to which deontological intuitions respond, in which case the neuroscientific results end up playing no role in the overall argument.

Robert Nozick's experience machine thought experiment is often considered a decisive refutation of hedonism. I argue that the conclusions we draw from Nozick's thought experiment ought to be informed by considerations concerning the operation of our intuitions about value. First, I argue that, in order to show that practical hedonistic reasons are not causing our negative reaction to the experience machine, we must not merely stipulate their irrelevance (since our intuitions are not always responsive to stipulation) but fill in the (...) concrete details that would make them irrelevant. If we do this, we may see our feelings about the experience machine becoming less negative. Second, I argue that, even if our feelings about the experience machine do not perfectly track hedonistic reasons, there are various reasons to doubt the reliability of our anti-hedonistic intuitions. And finally, I argue that, since in the actual world seeing certain things besides pleasure as ends in themselves may best serve hedonistic ends, hedonism may justify our taking these other things to be intrinsically valuable, thus again making the existence of our seemingly anti-hedonistic intuitions far from straightforward evidence for the falsity of hedonism.

Evolutionary debunking arguments are arguments that appeal to the evolutionary origins of evaluative beliefs to undermine their justification. This paper aims to clarify the premises and presuppositions of EDAs—a form of argument that is increasingly put to use in normative ethics. I argue that such arguments face serious obstacles. It is often overlooked, for example, that they presuppose the truth of metaethical objectivism. More importantly, even if objectivism is assumed, the use of EDAs in normative ethics is incompatible with a (...) parallel and more sweeping global evolutionary debunking argument that has been discussed in recent metaethics. After examining several ways of responding to this global debunking argument, I end by arguing that even if we could resist it, this would still not rehabilitate the current targeted use of EDAs in normative ethics given that, if EDAs work at all, they will in any case lead to a truly radical revision of our evaluative outlook.
