Proponents of impure moral perception claim that, while there are perceptual moral experiences, these experiences epistemically depend on a priori moral knowledge. Proponents of pure moral perception claim that moral experiences can justify independently of substantive a priori moral knowledge. Some philosophers, most notably David Faraci, have argued that the pure view is mistaken, since moral perception requires previous moral background knowledge, and such knowledge could not itself be perceptual. I defend pure moral perception against this objection. I consider two (...) ways to understand the notion of “background knowledge” that is crucial to the objection. On a reading, the claim that background knowledge is necessary for moral perception is likely false. On a second and weaker reading, the claim is true, but the background knowledge in question could be perceptual, and thus compatible with pure moral perception. Thus, the objection fails. (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.

There are several important arguments in metaethics that rely on explanatory considerations. Gilbert Harman has presented a challenge to the existence of moral facts that depends on the claim that the best explanation of our moral beliefs does not involve moral facts. The Reliability Challenge against moral realism depends on the claim that moral realism is incompatible with there being a satisfying explanation of our reliability about moral truths. The purpose of this chapter is to examine these and related arguments. (...) In particular, this chapter will discuss four kinds of arguments – Harman’s Challenge, evolutionary debunking arguments, irrelevant influence arguments, and the Reliability Challenge – understood as arguments against moral realism. The main goals of this chapter are (i) to articulate the strongest version of these arguments; (ii) to present and assess the central epistemological principles underlying these arguments; and (iii) to determine what a realist would have to do to adequately respond to these arguments.

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)

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)

This chapter discusses epistemic objections to non-naturalist moral realism. The goal of the chapter is to determine which objections are pressing and which objections can safely be dismissed. The chapter examines five families of objections: (i) one involving necessary conditions on knowledge, (ii) one involving the idea that the causal history of our moral beliefs reflects the significant impact of irrelevant influences, (iii) one relying on the idea that moral truths do not play a role in explaining our moral beliefs, (...) (iv) one involving the claim that if moral realism is true then our moral beliefs are unlikely to be reliable, and (v) one involving the claim that moral realism is incompatible with there being a plausible explanation of our reliability about morality. The overall conclusion of the chapter is that the final objection is by far the most pressing. (shrink)

This article explores the respective roles that medical and technological cognitive enhancements, on the one hand, and the moral and epistemic virtues traditionally understood, on the other, can play in enabling us to lead the good life. It will be shown that neither the virtues nor cognitive enhancements (of the kind we have access to today or in the foreseeable future) on their own are likely to enable most people to lead the good life. While the moral and epistemic virtues (...) quite plausibly are both necessary and sufficient for the good life in theory, virtue ethics is often criticised for being elitist and unachievable in practice for the vast majority. Some cognitive enhancements, on the other hand, might be necessary for the good life but are far from sufficient for such an existence. Here it will be proposed that a combination of virtue and some cognitive enhancements is preferable. (shrink)

This dissertation examines the psychology of moral judgment and its implications for normative ethics and metaethics. Recent empirical findings in moral psychology, such as the impact of emotions, intuitions, and situational factors on moral judgments, have sparked a debate about whether ordinary moral judgments are systematically error-prone. Some philosophers, such as Peter Singer and Joshua Greene, argue that these findings challenge the reliability of moral intuitions and support more "reasoned", consequentialist approaches over deontological ones. The first part of the dissertation (...) reviews these provocative findings and the philosophical reactions to them, which often invoke the notion of 'moral relevance' - the idea that some factors shaping moral judgments are morally irrelevant. The second part develops a psychological account of moral relevance, drawing on theories of the moral domain, the role of emotions, and models of moral cognition. This account reveals the complex interplay of intuitive and reasoned processes in generating impressions of moral relevance. The final part reevaluates the philosophical discussions in light of this psychological understanding. It contends that the evolutionary background of moral intuitions does not necessarily render them inadequate, and that both deontological and consequentialist judgments likely depend on evolved intuitions to a significant degree. Furthermore, the tendency to dismiss certain influences on moral judgment as irrelevant can itself be explained psychologically. Considering the psychological account presented, mind-independent accounts of morality become less plausible. The dissertation concludes that while empirical moral psychology reveals important constraints on normative theorizing, it does not decisively favor consequentialism over deontology. To assess the significance of empirical-scientific findings for ethics, a nuanced understanding of the origins of moral judgments is nevertheless indispensable. (shrink)

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)

Debunking arguments against both moral and mathematical realism have been pressed, based on the claim that our moral and mathematical beliefs are insensitive to the moral/mathematical facts. In the mathematical case, I argue that the role of Hume’s Principle as a conceptual truth speaks against the debunkers’ claim that it is intelligible to imagine the facts about numbers being otherwise while our evolved responses remain the same. Analogously, I argue, the conceptual supervenience of the moral on the natural speaks presents (...) a difficulty for the debunker’s claim that, had the moral facts been otherwise, our evolved moral beliefs would have remained the same.

This chapter offers an overview of four key debates about the roles of emotion in morality. First, many believe that emotions are an important psychological mechanism for explaining altruistic behavior and moral conscience in humans. Second, there is considerable debate about the causal role of affective reactions in moral judgment. Third, some philosophers have argued that emotions have a constitutive role in moral thought and even moral facts. Finally, philosophers disagree about whether affective influence undermines the justification of moral beliefs (...) or, in suitable circumstances, guides us toward moral truth. (shrink)

This chapter examines the influence of the empirical sciences (e.g., physics, biology, psychology) in contemporary analytic philosophy, with focus on philosophical theories that are guided by findings from the empirical sciences. Scientific approaches to philosophy follow a tradition of philosophical naturalism associated with Quine, which strives to ally philosophical methods and theories more closely with the empirical sciences and away from a priori theorizing and conceptual analysis.

I stipulate that an academic discipline is societally relevant insofar as it helps to resolve a society’s real problems. What makes such a view correct depends on meta-normative views. I show how one’s meta-normative view significantly determines the likelihood that disciplinary philosophy is of societal relevance. On normative non-naturalism, normative naturalism, and normative scepticism, the societal relevance of philosophy is in doubt. I then argue that philosophers should aim for two remedies. They should be what I call omnivores and 'synthesisers, (...) aiming for empirically sound knowledge and interdisciplinary integration to achieve societal relevance independently of the correct meta-normative view.

I discuss Benacerraf's epistemological challenge for realism about areas like mathematics, metalogic, and modality, and describe the pluralist response to it. I explain why normative pluralism is peculiarly unsatisfactory, and use this explanation to formulate a radicalization of Moore's Open Question Argument. According to the argument, the facts -- even the normative facts -- fail to settle the practical questions at the center of our normative lives. One lesson is that the concepts of realism and objectivity, which are widely identified, (...) are actually in tension. (shrink)

Arguments attempting to debunk moral beliefs, by showing they are unjustified, have tended to be global, targeting all moral beliefs or a large set of them. Popular debunking arguments point to various factors purportedly influencing moral beliefs, from evolutionary pressures, to automatic and emotionally-driven processes, to framing effects. We show that these sweeping arguments face a debunker’s dilemma: either the relevant factor is not a main basis for belief or it does not render the relevant beliefs unjustified. Empirical debunking arguments (...) in ethics can avoid this predicament, but only if they are refocused on highly selective classes of moral belief. Experimental data can combine with familiar consistency reasoning to reveal that like cases are not being treated alike. Selective debunking arguments are unlikely to yield sweeping sceptical conclusions, but they can lead to rational moral change. (shrink)

According to moral error theory, morality is something invented, constructed or made; but mistakenly presents itself to us as if it were an independent object of discovery. According to moral constructivism, morality is something invented, constructed or made. In this paper I argue that constructivism is both compatible with, and in certain cases explanatory of, some of the allegedly mistaken commitments to which arguments for moral skepticism appeal. I focus on two particular allegations that are sometimes associated with moral skepticism. (...) The first is the suspicion that in making moral claims we are merely projecting our attitudes onto the world. The second is the suspicion that in arguing for and against moral views we are merely attempting to influence each other to give similar answers to questions that have no determinate answer.

In this chapter, we will investigate the ramifications of moral knowledge for naturalism (roughly, the view that all that exists is the natural world). Specifically, we will draw attention to a certain problem we face if the world is purely naturalistic. We will then show how theism provides resources for solving this problem. We’ll argue that the fact that we have lots of moral knowledge fi ts better with theism than with naturalism. Specifically, we’ll present reasons to think that (1) (...) naturalists who think we have lots of moral knowledge will have trouble rationally maintaining both their naturalism and their belief that we have such knowledge and (2) theism better explains the fact that we have lots of moral knowledge than naturalism does.

Unlike any other field, the science of morality has drawn attention from an extraordinarily diverse set of disciplines. An interdisciplinary research program has formed in which economists, biologists, neuroscientists, psychologists, and even philosophers have been eager to provide answers to puzzling questions raised by the existence of human morality. Models and simulations, for a variety of reasons, have played various important roles in this endeavor. Their use, however, has sometimes been deemed as useless, trivial and inadequate. The role of models (...) in the science of morality has been vastly underappreciated. This omission shall be remedied here, offering a much more positive picture on the contributions modelers made to our understanding of morality. (shrink)

I discuss the structure of genealogical debunking arguments. I argue that they undermine our mathematical beliefs if they undermine our moral beliefs. The contrary appearance stems from a confusion of arithmetic truths with (first-order) logical truths, or from a confusion of reliability with justification. I conclude with a discussion of the cogency of debunking arguments, in light of the above. Their cogency depends on whether information can undermine all of our beliefs of a kind, F, without giving us direct reason (...) to doubt that our F-beliefs are modally secure. (shrink)

What are the consequences, for human moral practice, of an evolutionary understanding of that practice? By ‘moral practice’ we mean the way in which human beings think, talk and debate in moral terms. We suggest that the proper upshot of such considerations is moderate support for anti-realism in ethics.

This chapter develops Moral Occasionalism, according to which moral facts are grounded in certain natural facts, which are called sub-moral grounds, and these sub-moral grounds influence us in such a way as to induce largely correct moral beliefs. Moral Occasionalism is designed to explain the correlation of moral beliefs with the moral facts—and to do so in a way that is consistent with non-interactionist views, according to which moral facts neither influence nor are influenced by moral beliefs. It is argued (...) that moral non-naturalists and others who are committed to non-interactionist views ought to be in the business of defending Moral Occasionalism. The chapter shows that Moral Occasionalism has major advantages over its chief non-interactionist rival, namely David Enoch’s “godless pre-established harmony” view. The chapter anticipates and responds to several objections. (shrink)

Imagine coming across an alternative community such that, while they have normative terms like 'ought' with the same action-guiding roles and relationships to each other, their normative terms come to pick out different properties. When we come across such a community, or even just imagine it, those of us who strive to be moral and rational want to ask something like the following: Further Question: Which set of concepts ought we use—theirs or ours? The problem, first raised by Eklund, is (...) that on almost any metasemantic theory, Further Question cannot be stated in a way that captures the spirit of what we want to ask. This is because any way of asking the question makes use of our own normative concepts, and thus their reference is already fixed on the properties that our current normative concepts refer to. Any purported solution to this problem must meet two conditions. First, it must capture the spirit of what Further Question is intuitively attempting to ask. Second, it must reframe the inquiry in a way that makes the answer neither trivial nor ineffable. In this paper, I propose a solution to this problem by appeal to edenic representation, inspired by, but not identical to, Chalmers’ notion of edenic content. The rough idea here is that representation is edenic to the extent that the representational vehicle mirrors, in quality and structure, the represented property. I argue that a reframing of Further Question in terms of edenic representation can capture the spirit of the question, without collapsing it into a question with a trivial or ineffable answer. Thus, the realist about normative properties can face the problem of the alternative normative community head on, without collapsing into incoherence or triviality. If correct, this solution is of further interest to any metanormative realist concerned with metasemantic questions, because it can tell us more about how the proper representation of the robustly normative would look.

In metaethics, evolutionary debunking arguments combine empirical and epistemological premises to purportedly show that our moral judgments are unjustified. One objection to these arguments has been to distinguish between those judgments that evolutionary influence might undermine versus those that it does not. This response is powerful but not well understood. In this paper I flesh out the response by drawing upon a familiar distinction in the natural sciences, where it is common to distinguish folk judgments from theoretical judgments. I argue (...) that this in turn illuminates the proper scope of the evolutionary debunking argument, but not in an obvious way: it is a very specific type of undermining argument that targets those theories where theoretical judgments are inferred merely from folk judgments. One upshot of this conclusion is that it reveals a verboten methodology in metaethics. The evolutionary debunking argument is therefore much less powerful than its proponents have supposed, but it nevertheless rules out what is perhaps a common way of attempting to justify moral judgments.

The idea that there are some facts that call for explanation serves as an unexamined premise in influential arguments for the inexistence of moral or mathematical facts and for the existence of a god and of other universes. This book is the first to offer a comprehensive and critical treatment of this idea. It argues that calling for explanation is a sometimes-misleading figure of speech rather than a fundamental property of facts.

This paper develops an interpretation of Nietzsche’s ethics and metaethics that reconciles his apparent antirealism with his engagement in normative discourse. Interpreting Nietzsche as a metaethical constructivist—as holding, to a first approximation, that evaluative facts are grounded purely in facts about the evaluative attitudes of the creatures to whom they apply—reconciles his vehement declarations that nothing is valuable in itself with his passionate expressions of a particular evaluative perspective and injunctions for the free spirits to create new values. Drawing on (...) Nietzsche’s broader epistemological and psychological views, I develop a distinctive, and genuinely Nietzschean, version of constructivism. On this account, evaluative properties are grounded in affective valuations of the new philosophers. The proposed interpretation synthesizes a variety of disparate features of Nietzsche’s writings and improves on existing interpretations in the literature. The resulting version of constr.. (shrink)

In this article, I explore the method of genealogy in moral philosophy, with a focus on evaluating the credibility of moral progress judgments. Despite genealogy becoming a new trend in this field, I critique three types of defective grand narrative genealogies represented by the works of Peter Railton, Michael Huemer, and Nicholas Smyth. I argue that their genealogies fail to be adequate for evaluating moral progress judgments’ credibility. Railton’s genealogy lacks specificity regarding the relatum of the causal story he presents, (...) Huemer’s fails to withstand the scrutiny of historical evidence, and Smyth’s gives no clear verdict on the credibility of the moral progress judgments it explains. These failures, I argue, stem from grand narratives’ neglect of the particularities in each case of moral belief emergence. The disregard for details renders grand narratives generally inadequate for credibility evaluation. Instead, I propose a case study approach that takes into account four types of particulars in each case. I argue that this approach is more methodologically adequate in evaluating the credibility of moral progress judgments since these case-specific details are essential in determining the credibility of a moral belief.

The thesis investigates the implications for moral philosophy of research in psychology. In addition to an introduction and concluding remarks, the thesis consists of four chapters, each exploring various more specific challenges or inputs to moral philosophy from cognitive, social, personality, developmental, and evolutionary psychology. Chapter 1 explores and clarifies the issue of whether or not morality is innate. The chapter’s general conclusion is that evolution has equipped us with a basic suite of emotions that shape our moral judgments in (...) important ways. Chapter 2 presents and investigates the challenge presented to deontological ethics by Joshua Greene’s so-called dual process theory. The chapter partly agrees with his conclusion that the dual process view neutralizes some common criticisms against utilitarianism founded on deontological intuitions, but also points to avenues left to explore for deontologists. Chapter 3 focuses on Katarzyna de Lazari-Radek and Peter Singer’s suggestion that utilitarianism is less vulnerable to so-called evolutionary debunking than other moral theories. The chapter is by and large critical of their attempt. In the final chapter 4, attention is directed at the issue of whether or not social psychology has shown that people lack stable character traits, and hence that the virtue ethical view is premised on false or tenuous assumptions. Though this so-called situationist challenge at one time seemed like a serious threat to virtue ethics, the chapter argues for a moderate position, pointing to the fragility of much of the empirical research invoked to substantiate this challenge while also suggesting revisions to the virtue-ethical view as such.

Can there be an objective morality without God? Derek Parfit argues that it can and offers a theory of morality that is neither theistic nor naturalistic. This book provides a critical assessment of Parfit's metaethical theory. Jakobsen identifies some problems in Parfit’s theory – problems concerning moral normativity, the ontological status of morality, and evolutionary influence on our moral beliefs – and argues that theological resources can help solve them. By showing how Parfit’s theory may be improved by the help (...) of theology, Jakobsen demonstrates the relevance of theology in philosophical and metaethical debates and argues that Christian theism offers a better explanation of morality than what Parfit’s non-naturalism does.

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)

Recently some philosophers suggested an exclusion problem for moral non-naturalism, which is similar to the exclusion problem in philosophy of mind. In this article, the author aims to advance the discussion of exclusion in morality by investigating two influential solutions to the exclusion problem: the autonomy solution and the overdetermination solution. The author attempts to show that the moral non-naturalist can solve the exclusion problem in a way that is different from the approach to solving mental-physical exclusion. First, the author (...) argues that while the autonomy solution to mental exclusion may work, a similar autonomy approach to moral exclusion is implausible. Second, the author argues that whereas the overdetermination solution to mental exclusion fails, a similar overdetermination solution to moral exclusion is promising. (shrink)

I critically discuss Sutton’s 2012 attempt to solve the so-called “grounding problem” for coincident objects, namely, the difficulty of explaining how such objects, such as a statue and the lump of clay from which it was made, can have distinct kind and modal properties, even though they share the same proper parts and basic microphysical properties. Sutton bases her solution on an account of the extrinsic composition of the different sorts of objects involved in such cases - in particular, artefacts, (...) organisms and persons. I show that the accounts she gives of their composition are flawed, and that her proposal therefore does not solve the grounding problem. (shrink)

In this paper I clarify a major affinity between Nietzsche and Spinoza that has been neglected in the literature—but that Nietzsche was aware of—namely a tendency to what I call etiology. Etiologies provide second- order explanations of some opponents’ first-order views, but not in order to decide first-order matters. The example I take up here is Nietzsche’s and Spinoza’s rejections of free will—and especially their etiologies concerning how we wrongly come to think that we may boast of such a capacity. (...) In working through the former (i.e., their rejections of free will) in order to make my central metaphilosophical point regarding the latter (i.e., their accounts of why we generally affirm that we have free will), I shed important new light on Nietzsche’s relation to Spinoza. I also further our understanding of what role such second-order accounts play within each of their larger projects on their own terms. (shrink)

Debunking arguments in ethics contend that our moral beliefs have dubious evolutionary, cultural, or psychological origins—hence concluding that we should doubt such beliefs. Debates about debunking are often couched in coarse-grained terms—about whether our moral beliefs are justified or not, for instance. In this paper, I propose a more detailed Bayesian analysis of debunking arguments, which proceeds in the fine-grained framework of rational confidence. Such analysis promises several payoffs: it highlights how debunking arguments don’t affect all agents, but rather only (...) those agents who updated on their intuitions using a specific range of evidentiary weights; it underscores how the debunkers shouldn’t conclude that we should reduce confidence beyond some threshold, but rather only that we should reduce confidence by some amount; and it proposes a method of integrating different kinds of evidence—about the kinds of epistemic flaws at play, about the different possible origins of our moral beliefs, about the background normative assumptions we’re entitled to make—in order to arrive at a rational moral credence in light of debunking.

Science promises benefits, some true and some illusory. Consider a scientific agnostic who thinks that to reap the true benefits of a scientific theory he does not have to believe in its theoretical posits. Instead, it is enough if he believes that the theory successfully predicts the behavior of the observables, as ultimately only such predictions matter. -/- Say, however, that given the results of her thorough research, a psychologist proposes a theory describing a psychological mechanism underlying a certain class (...) of normative judgments. Moreover, the mechanism seems unfit for the task—once you see the details of the mechanism, you will realize that this is not the way they should be produced. Therefore, if the psychologist is right, it seems that these normative judgments should not inform one's normative theorizing or one's actions (Greene 2008, 2014, Kelly 2014). And say that the agnostic accepts the psychologist's theory, trusting that it makes correct predictions about, for example, fMRI images and subjects' reaction times, as they are observable. He also thinks that if the psychologist's description of the mechanism is correct, the judgments should not be trusted. Yet, since the mechanism posited by the theory is not observable, the agnostic is agnostic about it. He thus cannot be convinced that these judgments are produced in a flawed way and, consequently, has no reason to distrust them. -/- Scientific agnosticism comes, therefore, at the cost of dismissing normative arguments that invoke unobservable posits of psychological models. The ability to make such arguments is a true (rather than illusory) benefit of science, despite the agnostic's promise that his philosophical theory leaves intact benefits that genuinely matter.

An important strand in the debate on abortion focuses on the moral status of fetuses. Knowledge of the moral value of fetuses is needed to assess fetuses’ moral status. As Errol Lord argues, acquaintance plays a key role in moral and aesthetic knowledge. Many pregnant persons have acquaintance with their fetus that provides privileged access to knowledge about that fetus’ moral value. This knowledge is (a) very difficult to acquire without being pregnant and (b) relevant for assessing the moral status (...) of fetuses. This has implications for public debate on abortion and the research methods of philosophers working on abortion. (shrink)

Philosophical arguments usually are and nearly always should be abductive. Across many areas, philosophers are starting to recognize that often the best we can do in theorizing some phenomena is put forward our best overall account of it, warts and all. This is especially true in esoteric areas like logic, aesthetics, mathematics, and morality where the data to be explained is often based in our stubborn intuitions. -/- While this methodological shift is welcome, it's not without problems. Abductive arguments involve (...) significant theoretical resources which themselves can be part of what's being disputed. This means that we will sometimes find otherwise good arguments which suggest their own grounds are problematic. In particular, sometimes revising our beliefs on the basis of such an argument can undermine the very justification we used in that argument. -/- This feature, which I'll call self-effacingness, occurs most dramatically in arguments against our standing views on the esoteric subject matters mentioned above: logic, mathematics, aesthetics, and morality. This is because these subject matters all play a role in how we reason abductively. This isn't an idle fact; we can resist some challenges to our standing beliefs about these subject matters exactly because the challenges are self-effacing. The self-effacing character of certain arguments is thus both a benefit and limitation of the abductive turn and deserves serious attention. I aim to give it the attention it deserves. (shrink)

I argue that certain species of belief, such as mathematical, logical, and normative beliefs, are insulated from a form of Harman-style debunking argument whereas moral beliefs, the primary target of such arguments, are not. Harman-style arguments have been misunderstood as attempts to directly undermine our moral beliefs. They are rather best given as burden-shifting arguments, concluding that we need additional reasons to maintain our moral beliefs. If we understand them this way, then we can see why moral beliefs are vulnerable (...) to such arguments while mathematical, logical, and normative beliefs are not—the very construction of Harman-style skeptical arguments requires the truth of significant fragments of our mathematical, logical, and normative beliefs, but requires no such thing of our moral beliefs. Given this property, Harman-style skeptical arguments against logical, mathematical, and normative beliefs are self-effacing; doubting these beliefs on the basis of such arguments results in the loss of our reasons for doubt. But we can cleanly doubt the truth of morality. (shrink)

An influential species of evolutionary debunking argument against moral realism holds that since cumulative natural selection shaped the contents of our moral beliefs, those beliefs do not count as knowledge. Critics have taken issue with a range of empirical, epistemic, and metaphysical assumptions that EDAs are said to rely on, which has engendered a complex debate over whether and to what extent the debunking challenge succeeds. However, recently it has been argued that we can reject EDAs without having to enter (...) this thicket of issues. EDAs supposedly fail at the outset, by trading on a glaring misunderstanding about the scope of natural selection explanations. I argue that this objection to EDAs fails, and itself rests on a mistaken view of natural selection explanation and its relation to justification. (shrink)

A common line of thought in contemporary metaethics is that certain facts about the evolutionary history of humans make moral realism implausible. Two of the most developed evolutionary cases against realism are found in the works of Richard Joyce and Sharon Street. In what follows, I argue that a form of moral realism that I call proper-function moral realism can meet Joyce and Street's challenges. I begin by sketching the basics of proper-function moral realism. I then present what I take (...) to be the essence of Street's and Joyce's objections, and I show how proper-function realism answers them. (shrink)

Terence Cuneo has recently argued that we have to be committed to the existence of epistemic facts insofar as they are indispensable to theorizing. Furthermore, he argues that the epistemic properties of these facts are inextricably ‘ontologically entangled’ with certain moral properties, such that there exist ‘moral-epistemic’ facts. Cuneo, therefore, concludes that moral realism is true. I argue that Cuneo’s appeal to the existence of moral-epistemic facts is problematic, even granting his argument for the existence of indispensable epistemic facts. I (...) conclude, therefore, that Cuneo’s argument fails to justify moral realism. (shrink)

The naturalistic approach to metaethics is sometimes identified with a supervenience theory relating moral properties to underlying descriptive properties, thereby securing the possibility of objective knowledge in morality as in chemistry. I reject this approach along with the purely anthropological approach which leads to an objectionable form of relativism. There is no single method for arriving at moral objectivity any more than there is a single method that has taken us from alchemy to modern chemistry. Rather, there is an ensemble (...) of instruments, techniques, experiments and observations that contribute to eliminating moral error, delivering what we are entitled to call greater objectivity.

This paper focuses on an early Chinese conception of genealogical argumentation in the late Warring States text Han Feizi and a possible response it has to the problem of genealogical self-defeat as identified by Amia Srinivasan —i.e., the genealogist cannot seem to support their argument with premises their interlocutor or they themselves can accept, given their own argument. The paper offers a reading of Han Fei’s genealogical method that traces back to the meditative practice of an earlier Daoist text the (...)
