This paper explores evolutionary debunking arguments as they arise in metaethics against moral realism and in philosophy of religion against naturalism. Both literatures have independently grappled with the question of which beliefs one may use to respond to a potential defeater. In this paper, I show how the literature on the argument against naturalism can help clarify and bring progress to the literature on moral realism with respect to this question. Of note, it will become clear that the objection that (...) the moral realist begs the question, when appealing to the truth of some of her moral beliefs, is unsuccessful. (shrink)

Evolutionary debunking arguments claim that evolution has influenced our moral faculties in such a way that, if moral realism is true, then we have no positive moral knowledge. I present several popular objections to the standard version of this argument, then give a new EDA that has clear advantages in responding to these objections. Whereas the Standard EDA argues that evolution has selected for many moral beliefs with certain contents, this New EDA claims that evolution has selected for one belief: (...) belief in the claim that categorical reasons exist. If moral realism is true, then this claim is entailed by all positive moral claims, and belief in it is defeated due to evolutionary influence. This entails that if realism is true, then we have no positive moral knowledge. While there may be objections against this New EDA, it is much stronger than the Standard EDA, and one realists ought to worry about. (shrink)

Joshua Greene has put forward the bold empirical hypothesis that deontology is a confabulation of moral emotions. Deontological philosophy does not steam from "true" moral reasoning, but from emotional reactions, backed up by post hoc rationalizations which play no role in generating the initial moral beliefs. In this paper, I will argue against the confabulation hypothesis. First, I will highlight several points in Greene’s discussion of confabulation, and identify two possible models. Then, I will argue that the evidence does not (...) illustrate the relevant model of deontological confabulation. In fact, I will make the case that deontology is unlikely to be a confabulation because alarm-like emotions, which allegedly drive deontological theorizing, are resistant to be subject to confabulation. I will end by clarifying what kind of claims can the confabulation data support. The upshot of the final section is that confabulation data cannot be used to undermine deontological theory in itself, and ironically, if one commits to the claim that a deontological justification is a confabulation in a particular case, then the data suggests that in general deontology has a prima facie validity.

This paper is a survey of the supervenience challenge to non-naturalist moral realism. I formulate a version of the challenge, consider the most promising non-naturalist replies to it, and suggest that no fully effective reply has yet been given.

It has long been claimed that moral judgements are dominated by reason. In recent years, however, the tide has turned. Many psychologists and philosophers now hold the view that there is a close empirical association between moral judgements and emotions. In particular, they claim that emotions (1) co-occur with moral judgements, (2) causally influence moral judgements, (3) are causally sufficient for moral judgements, and (4) are causally necessary for moral judgements. At first sight these hypotheses seem well-supported. In this paper (...) I show, however, that appearances are deceiving. If one considers the relevant scientific studies in detail, one finds that in many interpretations the above hypotheses are either not supported or even contradicted by the available evidence. This conclusion is significant both for our understanding of moral judgements qua empirical phenomena and for normative ethics and metaethics. (shrink)

According to robust moral realism, there exist objective, non-natural moral facts. Moral facts of this sort do not fit easily into the world as illuminated by natural science. Further, if such facts exist at all, it is hard to see how we could know of their existence by any familiar means. Yet robust realists are not moral skeptics; they believe that we do know the moral facts. Thus robust moral realism comes with a number of hard-to-defend ontological and epistemological commitments. (...) Recently, Sharon Street has claimed, in light of these commitments, that robust moral realism requires a kind of faith and “has become a strange form of religion.” I believe that Street is right. I argue at some length that robust moral realism does require faith, and is a religion. However, I further argue that it is an excellent religion. I argue that it has three principal advantages: it is avoids wishful thinking, is guaranteed not to contradict the results of natural science, and is profoundly simple in its ontological commitments. Further, robust moral realism may be rationally defensible on evidentialist grounds. Consequently, even if the standard arguments for traditional religions are not compelling, there might still be compelling arguments for robust moral realism. (shrink)

In this article, I argue that God is authoritative over us because he is our divine, causal parent. As our causal parent, God has duties to relate to us, but he can only fulfill those duties if he has the practical authority to give us commands aimed at our sanctification. From ought-implies-can reasoning, I conclude that God has that authority. After I make this argument, I show how the view has significant advantages over extant arguments for divine authority and can (...) help solve other significant problems in philosophy of religion.

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.

Many hope that our values, purged of messy human contingency, could aspire to correspond with mind-independent, rationally obligatory, and eternal ethical facts. But if the arguments of this thesis are on the right track, we should reject the search for non-natural and mind-independent moral truths.

Moral realism faces a well known genealogical debunking challenge. I argue that the moral realist’s best response may involve abandoning metaphysical naturalism in favor of some form of axiarchism—the view, very roughly, that the natural world is “ordered to the good.” Axiarchism comes in both theistic and non-theistic forms, but all forms agree that the natural world exists and has certain basic features because it is good for it to exist and have those features. I argue that theistic and non-theistic (...) forms of axiarchism are better positioned than metaphysical naturalism to avoid two commitments that a moral realist should seek to avoid: that the correctness of our moral beliefs is a major coincidence, and that there is a complete explanation of our moral beliefs that does not mention any moral truths. (shrink)

Non-naturalism is the view that there are sui generis, non-natural moral properties. This paper poses a dilemma for theists who accept this view. Either God explains why non-moral properties make sui generis, non-natural moral properties obtain, or God does not explain this. If the former, then God is unacceptably involved in the explanation of his own moral goodness. If the latter, then God’s sovereignty, stature, and importance are undermined, and an unacceptable queerness is introduced into the world. This paper concludes (...) that theists have good reasons to reject non-naturalism on account of the unacceptable consequences of accepting either horn. (shrink)

What is it that we are doing when we make ethical claims and judgments, such as the claim that we morally ought to assist refugees? This dissertation introduces and defends a novel theory of ethical thought and discourse. I begin by identifying the surface features of ethical thought and discourse to be explained, including the realist and cognitivist (i.e. belief-like) appearance of ethical judgments, and the apparent close connection between making a sincere ethical judgment and being motivated to act on (...) it. I examine prominent attempts to explain these features, with a focus on recent ‘hybrid’ theories combining elements of expressivism and cognitivism. Despite their initial promise, I argue that extant hybrid theories are nevertheless committed to problematic semantic, metasemantic, or pragmatic assumptions. I then discuss what I take to be the strongest existing option, ethical neo-expressivism (Bar-On and Chrisman, 2009; Bar-On, Chrisman, and Sias, 2014), and develop it into an explicitly hybrid theory proposing that ethical judgments incorporate both motivationally-charged affective states and moral beliefs. I then supplement this account with a theory of the proper function (following Millikan, 1984) of ethical claims and judgments, arguing that they function simultaneously to track the morally salient features of social situations, and to coordinate our behavior around these features. Finally, I defend one of the cognitivist commitments of the theory – namely, that objective moral knowledge is possible – by applying recent work on the epistemology of fundamental or ‘core’ intellectual commitments (Lynch, 2012; Pritchard, 2016) to the moral realm.

The Reliability Challenge to moral non-naturalism has received substantial attention recently in the literature on moral epistemology. While the popularity of this particular challenge is a recent development, the challenge has a long history, as the form of this challenge can be traced back to a skeptical challenge in the philosophy of mathematics raised by Paul Benacerraf. The current Reliability Challenge is widely regarded as the most sophisticated way to develop this skeptical line of thinking, making the Reliability Challenge the (...) strongest epistemic challenge to normative nonnaturalism. In this paper, I argue that the innovations that have occurred since Benacerraf’s statement of the challenge are misconceived and confused in a number of ways. The Reliability Challenge is not the most potent epistemic challenge to moral non-naturalism. The most potent challenge comes from the fact that there is a causal condition on knowledge – or, more precisely, a becaual condition – that non-natural moral facts cannot satisfy. (shrink)

Metaethical debunking arguments often conclude that no moral belief is epistemically justified. Early versions of such arguments largely relied on metaphors and analogies and left the epistemology of debunking underspecified. Debunkers have since come to take on substantial and broad-ranging epistemological commitments. The plausibility of metaethical debunking has thereby become entangled in thorny epistemological issues. In this thesis, I provide a critical yet sympathetic evaluation of the prospects and challenges facing such arguments in light of this development. In doing so, (...) I address the following central question: how could genealogical information undermine the epistemic justification of moral beliefs? In Part I, I begin answering the central question by extracting explicit and implicit epistemic principles from three popular debunking arguments. These arguments, due to Gilbert Harman, Richard Joyce, and Sharon Street, generate principles concerning ontological parsimony, explanatory dispensability, epistemic insensitivity, lack of epistemic safety, unexplained reliability, epistemic coincidences, and explanatory constraints on rational belief. Having set out the principles tasked with explaining how genealogical information undermines, Part II of the thesis seeks to evaluate whether debunking arguments built on them succeed. To this end, I consider two types of challenges faced by such arguments. First, there are strategies that attempt to block global moral debunking arguments. I argue that one popular such strategy, the so-called ‘third-factor strategy’, has been misunderstood. When understood correctly, it is of no help in answering debunking arguments. I then flesh out an alternative and more promising strategy for blocking such arguments. I then turn to internal challenges facing debunkers, particularly those who rely on ‘explanationist’ principles. I argue that explanationist debunking arguments, as well as most others, fall prey to one or more of four internal challenges: the implausibility of first-order epistemic principles, the threat of overgeneralization, the threat of self-defeat, and the need for costly metaepistemic commitments. I conclude that current debunking arguments fail to establish that no moral belief is justified. By analyzing why existing arguments fail, I develop two conditions of adequacy that debunkers must satisfy in order to navigate the internal challenges successfully. I end by suggesting future directions that debunkers should pursue to rehabilitate the prospects for global moral debunking arguments. (shrink)

The view that human law can be analyzed in terms of commands was subjected to devastating criticism by H. L. A. Hart in his 1961 The Concept of Law. Two objections that Hart levels against the command theory of law also make serious trouble for divine command theory. Divine command theorists would do well to jettison command as the central concept of their moral theory and, following Hart’s lead, instead appeal to the concept of a rule. Such a successor view—divine (...) legislation theory—has the attractions of divine command theory without the unacceptable limitations of command theories that Hart identifies. (shrink)

Erik Wielenberg [2014] and Mark Murphy [2017], [2018] have defended a series of arguments for the conclusion that creatures are not good intrinsically. In response, I take two steps. First, I introduce a conception of intrinsic value that makes created intrinsic value unproblematic. Second, I respond to their arguments in turn. The first argument is from the sovereignty-aseity intuition and an analysis of intrinsicality that makes derivative good extrinsic. I challenge the analysis. The second comes from a conception of perfection (...) where God exhausts all possibilities for goodness. I challenge this conception. The third comes from the contingency of creation and the internal logic of intrinsic value. I challenge the assumption that connects the two. I then present an argument from reference magnetism that the only conception of God, God's perfections, and religious language that makes it plausible that the sentence "God is intrinsically good and creatures are not" is true involves a strongly univocalist position. A view that is either unstatable or places strong demands on our conception of God, God's perfections and religious language thereby loses plausibility. (shrink)

There is now a burgeoning literature on evolutionary debunking arguments (EDAs) against moral beliefs, but perhaps surprisingly, a relatively small literature on EDAs against religious beliefs. There is an even smaller literature comparing the two. This essay aims to further the investigation of how the two sorts of arguments compare with each other. To begin with, I shall offer some remarks on how to best formulate these arguments, focusing on four different formulations that one can discern in the literature and (...) that can be applied to both sorts of beliefs. I shall then go on to make a series of comparisons regarding the relative vulnerabilities of moral beliefs and theistic religious beliefs to these four arguments, suggesting that there are a number of respects in which theistic religious beliefs are somewhat less liable than moral beliefs to be undercut by EDAs.

As a matter of fact, few, if any, theists have been expressivists about morality. This is probably because expressivism is thought to have unacceptable theological implications. That is, it is thought to imply (1) that God’s goodness depends on our desire-like states, (2) that God’s goodness is not a real property, (3) that it is not true that God is good, and (4) that God’s moral thoughts have no explanation. I argue that expressivism has no such implications and conclude that (...) expressivism is theologically acceptable. (shrink)

Traditional theism says that the goodness of everything comes from God. Moreover, the goodness of something intrinsically valuable can only come from what has it. Many conclude from these two claims that no creatures have intrinsic value if traditional theism is true. I argue that the exemplarist theory of the divine ideas gives the theist a way out. According to exemplarism, God creates everything according to ideas that are about himself, and so everything resembles God. Since God is wholly good (...) in every way, and since ethical supervenience is true, it follows that creatures have intrinsic value. (shrink)

Several theistic arguments are formulated as arguments for the best explanation. This article discusses how one can determine that some phenomenon actually needs an explanation. One way to demonstrate that an explanation is needed is by providing one. The proposed explanation ought to either make the occurrence of the phenomenon in question more probable than it occurring by chance, or it has to sufficiently increase our understanding of the phenomenon. A second way to demonstrate that an explanation is needed is (...) to show that the phenomenon in question both violates our expectations and is particularly noticeable. (shrink)

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.

This article examines two arguments that a worship-worthy agent cannot command worship. The first argument is based on the idea that any agent who commands worship is egotistical, and hence not worship-worthy. The second argument is based on Campbell Brown and Yujin Nagasawa's (2005) idea that people cannot comply with the command to worship because if people are offering genuine worship, they cannot be motivated by a command to do so. One might then argue that a worship-worthy agent would have (...) no reason to issue a command to worship. I argue that both these arguments fail. (shrink)

A familiar claim, meant as a challenge to moral knowledge, is that we can credibly accept putative moral facts just in case they explain natural facts. This paper critically addresses Elizabeth Tropman’s response to a version of that claim. Her response has interest partly because it falls within, and extends, an influential philosophical tradition – that of trying to expose (some) skeptical challenges as spurious or ill-conceived. Also, Tropman’s target is not just any version of the claim just mentioned. It (...) is Gilbert Harman’s classic version, according to which putative moral facts must earn credibility by explaining the formation of moral beliefs. This version has wide influence, and variations of it can arise in many areas. Tropman’s response is thus well worth attention. (shrink)

There has lately been substantial interest in scrutinizing our evaluative attitudes in light of our evolutionary history. However, these discussions have been hampered by an insufficiently expansive vantage. Our history did not begin ex nihilo a few million years ago with the appearance of hominins, or apes, or primates—those are very recent chapters of a much larger story that spans billions of years. This paper situates the mechanisms underlying normative thought within this broader context. I argue that this historical perspective (...) creates difficulties for metaethical nonnaturalists. The expanded scope enables the story to be anchored in negative claims about value, making room for novel epistemological and metaphysical challenges that are more threatening than extant evolutionary debunking arguments.

Street’s “Darwinian Dilemma” is a well-known epistemological objection to moral realism. In this paper, I argue that “third-factor” replies to this argument on behalf of the moral realist, as popularized by Enoch :413–438, 2010, Taking morality seriously: a defense of robust realism, Oxford University Press, Oxford, 2011), Skarsaune :229–243, 2011) and Wielenberg :441–464, 2010, Robust ethics: the metaphysics and epistemology of godless normative realism, Oxford University Press, Oxford, 2014), cannot succeed. This is because they are instances of the illegitimate form (...) of reasoning known as “bootstrapping.” The phenomenon of bootstrapping has been discussed in detail, most notably by Vogel :602–623, 2000) and Cohen :309–329, 2002), in a different context as an objection to reliabilism and related theories of knowledge. I introduce four different characterizations of the error of bootstrapping from the epistemic literature in order to argue that the form of reasoning exemplified by third-factor replies would be deemed illegitimate by every one of them. I conclude that the moral realist should abandon third-factor replies, or else suggest a novel diagnosis for what goes wrong in bootstrapping cases that does not apply equally to the realist’s form of argument. However, I am not optimistic about the prospects for this latter strategy. (shrink)

Este texto tem como objetivo apresentar a principal motivação filosófica para se defender uma teoria causal da memória, que é explicar como pode um evento que se deu no passado estar relacionado a uma experiência mnêmica que se dá no presente. Para tanto, iniciaremos apresentando a noção de memória de maneira informal e geral, para depois apresentar elementos mais detalhados. Finalizamos apresentando uma teoria causal da memória que se beneficia da noção de veritação (truthmaking).

Normative explanations, which specify why things have the normative features they do, are ubiquitous in normative theory and ordinary thought. But there is much less work on normative explanation than on scientific or metaphysical explanation. Skow (2016) argues that a complete answer to the question why some fact Q occurs consists in all of the reasons why Q occurs. This paper explores this theory as a case study of a general theory that promises to offer us a grip on normative (...) explanation which is independent of particular normative theories. I first argue that the theory doesn’t give an adequate account of certain enablers of reasons which are important in normative explanation. I then formulate and reject three responses on behalf of the theory. But I suggest that since theories of this general sort have the right kind of resources to illuminate how normative explanation might be similar to and different from explanations in other domains, they nonetheless merit further exploration by normative theorists.

Several moral objectivists try to explain the reliability of moral beliefs by appealing to a third factor, a substantive moral claim that explains, first, why we have the moral beliefs that we have and, second, why these beliefs are true. Folke Tersman has recently suggested that moral disagreement constrains the epistemic legitimacy of third-factor explanations. Apart from constraining third-factor explanations, Tersman’s challenge could support the view that the epistemic significance of debunking explanations depends on the epistemic significance of disagreement. This (...) paper aims to show that disagreement does not constrain the epistemic legitimacy of third-factor explanations in metaethics, and it suggests a way forward in addressing the view that debunking depends on disagreement. First, Tersman’s constraints are impossible to violate, given the assumption that the justification relation exhibits monotonicity. Second, some disagreements are irrelevant, given that they cannot be about beliefs whose reliability the objectivist seeks to defend. Third, actual disagreement about moral beliefs is implausible, given recent ethnographic findings. In light of this discussion, the paper shows that the prospects of the disagreement view depend on which moral beliefs objectivists need to defend and the criteria we use to assess epistemically relevant moral disagreement.

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)

In this introductory chapter, I not only present the essays that make up this volume but also I offer an extensive critical overview of moral skepticism with the hope that it will turn out to be useful particularly to the uninitiated reader. I first provide a taxonomy of varieties of moral skepticism, then discuss the main arguments advanced in their favor, and finally summarize the ten essays here collected, which deal with one or more of those skeptical stances and arguments.

Error theories have been proposed and defended in several different areas of philosophy. In addition to ethics, there are error theories about numbers, color, free will, and personal identity. Moral error theories differ in scope. Theories at one end of the spectrum take normative judgments in general—of which moral judgments are a subclass—to be uniformly false, whereas theories at the other end of the spectrum take only a subclass of moral judgments—example those concerning duty and obligation, but not those concerning (...) virtue and vice—to be uniformly false. Moral error theorists typically join forces with non-naturalist realists, against naturalism and non-cognitivism. Facts that are normative in the reason-implying sense are irreducibly normative, and they are very different. Many non-naturalist realists and error theorists maintain that it is impossible to give a plausible naturalistic account of moral facts, precisely because they are irreducibly normative; moral naturalism therefore falls prey to the "normativity objection".

Evolutionary debunking arguments purport to show that robust moral realism, the metaethical view that there are non-natural and mind-independent moral properties and facts that we can know about, is incompatible with evolutionary explanations of morality. One of the most prominent evolutionary debunking arguments is advanced by Sharon Street, who argues that if moral realism were true, then objective moral knowledge is unlikely because realist moral properties are evolutionary irrelevant and moral beliefs about those properties would not be selected for. However, (...) no evolutionary, causal explanation plays an essential role in reaching the argument’s epistemological conclusion. Street’s argument depends on the Benacerraf-Field challenge, which is the challenge to explain the reliability of our moral beliefs about causally inert moral properties. The Benacerraf-Field challenge relies on metaphysically necessary facts about realist moral properties, rather than on contingent Darwinian facts about the origin of our moral beliefs. Attempting to include an essential causal empirical premise yet avoiding recourse to the Benacerraf-Field problem yields an argument that is either self-defeating or of limited scope. Ultimately, evolutionary, causal explanations of our moral beliefs and their consequences do not present the strongest case against robust moral realism. Rather, the question is whether knowledge of casually-inert, mind-intendent properties is plausible at all. (shrink)

I address Andrew Moon's recent discussion (2016, this journal) of the question whether third-factor accounts are valid responses to debunking arguments against moral realism. Moon argues that third-factor responses are valid under certain conditions but leaves open whether moral realists can use his interpretation of the third-factor response to defuse the evolutionary debunking challenge. I rebut Moon's claim and answer his question. Moon's third-factor reply is valid only if we accept externalism about epistemic defeaters. However, even if we do, I (...) argue, the conditions Moon identifies for a valid third-factor response are not met in the case of moral realism. (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)

Divine command theories come in several different forms but at their core all of these theories claim that certain moral statuses exist in virtue of the fact that God has commanded them to exist. Several authors argue that this core version of the DCT is vulnerable to an epistemological objection. According to this objection, DCT is deficient because certain groups of moral agents lack epistemic access to God’s commands. But there is confusion as to the precise nature and significance of (...) this objection, and critiques of its key premises. In this article, I try to clear up this confusion and address these critiques. I do so in three ways. First, I offer a simplified general version of the objection. Second, I address the leading criticisms of the premises of this objection, focusing in particular on the role of moral risk/uncertainty in our understanding of God’s commands. And third, I outline four possible interpretations of the argument, each with a differing degree of significance for the proponent of the DCT. (shrink)

Metaethical realists disagree about the nature of normative properties. Naturalists think that they are ordinary natural properties: causally efficacious, a posteriori knowable, and usable in the best explanations of natural and social sciences. Non-naturalist realists, in contrast, argue that they are sui generis: causally inert, a priori knowable and not a part of the subject matter of sciences. It has been assumed so far that naturalists can explain causally how the normative predicates manage to refer to normative properties, whereas non-naturalists (...) are unable to provide equally satisfactory metasemantic explanations. This article first describes how the previous non-naturalist accounts of reference fail to tell us how the normative predicates could have come to refer to the non-natural properties rather than to the natural ones. I will then use the so-called qua-problem to show how the causal theories of reference of naturalists also fail to fix the reference of normative predicates to unique natural properties. Finally, I will suggest that, just as naturalists need to rely on the non-causal mechanism of reference magnetism to solve the previous problem, non-naturalists, too, can rely on the very same idea to respond to the pressing metasemantic challenges that they face concerning reference.

David Enoch has recently proposed that the deliberative indispensability of irreducibly normative facts suffices to support their inclusion in our ontology, even if they are not necessary for the explanation of any observable phenomena. He challenges dissenters to point to a relevant asymmetry between explanation and deliberation that shows why explanatory indispensability, but not deliberative indispensability, is a legitimate guide to ontology. In this paper, I aim to do just that. Given that an entity figures in the actual explanation of (...) some phenomenon, it is not an open question whether that entity exists. Thus, if you can manage to find actual explanations, you can find answers to ontological questions. In contrast, even if some entity is indispensable to deliberation, it still might not exist. For example, even if some form of libertarian free will is deliberatively indispensable, we still might not have libertarian free will. So even if you manage to discover the indispensable commitments of deliberation, there is still more work to do to get to the bottom of things. That additional work is explanatory work, and so deliberative indispensability is not an independent guide to what there is. (shrink)

In this thesis, I will explore the epistemological evolutionary debunking arguments in meta-ethics. I will defend these arguments by accomplishing two tasks: I will offer the best way to understand the EDA and I will also respond to two strongest objections to the EDA. Firstly, in Part I of this thesis, I will offer my account of how the EDA should be best formulated. I will start from how evolution has significantly influenced our moral beliefs. I will then explain why, (...) due to their evolutionary origin, our moral beliefs are not tracking the moral truth reliably. Furthermore, I will argue that the fact that our moral beliefs are not tracking the moral truth also provides an undercutting and a higher-order defeater for those beliefs. As a result, I will conclude that the epistemic status of our moral beliefs is undermined because of these two kinds of defeaters. Secondly, in Part II of this thesis, I will turn my attention to the two strongest objections to the EDA – the Conceptual Truth Objection and the Third Factor Objection. I will first offer two responses to the Conceptual Truth Objection and, based on these two responses, I will argue that the Conceptual Truth Objection fails as a challenge to the EDA. I will then also argue that there currently doesn’t exist an acceptable version of the Third Factor Objection and it is also unlikely that such a version could be constructed in the future. I will finally conclude that both objections are problematic and they are thus unable to give us reason to doubt the EDA. (shrink)

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)

: Recently, Erik Wielenberg has developed a novel objection to divine command meta-ethics. The objection that DCM "has the implausible implication that psychopaths have no moral obligations and hence their evil acts, no matter how evil, are morally permissible". This article criticizes Wielenberg's argument. Section 1 will expound Wielenberg's new "psychopath" argument in the context of the recent debate over the Promulgation Objection. Section 2 will discuss two ambiguities in the argument; in particular, Wielenberg’s formulation is ambiguous between whether Wielenberg (...) uses the word "obligation" in an objective or subjective sense. Section 3 will argue that this ambiguity undercuts the argument. If Wielenberg is using the word obligation in a subjective sense, his arguments do not show that that psychopaths "have no moral obligations". By contrast, if Wielenberg is using the word obligation in an objective sense, his arguments do not show that Divine command theorists are committed to denying psychopaths have obligations. (shrink)

Quasi-realist expressivists set themselves the task of developing a metaethical theory that at once captures what they call the “realist-sounding” elements of ordinary moral thought and discourse but is also distinctively antirealist. Its critics have long suspected that the position cannot have what it wants. In this essay, I develop this suspicion. I do so by distinguishing two paradigmatic versions of the view—what I call Thin and Thick expressivism respectively. I contend that there is a metaethical datum regarding our epistemic (...) achievements in the moral domain that presents challenges for each variety of expressivism. Thin expressivism opts not to accommodate and explain this datum but I contend that its rationale for not doing so rests on a suspect methodology. Thick expressivism looks as if it must accommodate and explain this datum but I argue that it is poorly situated to do so. I conclude that we have reason to believe that paradigmatic expressivism cannot have all that it wants. (shrink)

Theological stateist theories, the most well-known of which is Divine Command Theory (DCT), ground our moral obligations directly in some state of God. The prior obligations objection poses a challenge to theological stateism. Is there a moral obligation to obey God’s commands? If no, it is hard to see how God’s commands can generate any moral obligations for us. If yes, then what grounds this prior obligation? To avoid circularity, the moral obligation must be grounded independent of God’s commands; and (...) therefore DCT fails to ground all moral obligations in God’s commands. I argue that DCT proponents should embrace “metaethical DCT.” On this view, there is no moral obligation to obey God. God creates our moral obligations out of normative nothingness. I argue that this helps DCT proponents to escape the prior obligations objection. Other theological stateist theories can modify their theory similarly to meet this objection. (shrink)

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)

Debunking arguments in metaethics are often presented as particularly challenging for non‐naturalistic versions of moral realism. The first aim of this paper is to explore and defend a response on behalf of non‐naturalism. The second aim of the paper is to argue that although non‐naturalism’s response is satisfactory, this does not mean that debunking arguments are metaethically uninteresting. They have a limited and indirect role to play in the exchange between non‐naturalists and moral error theorists. In the end, debunking arguments (...) can do less for sceptics and nihilists than what is commonly thought, but not nothing. (shrink)

Many philosophers believe that when a theory is committed to an apparently unexplainable massive correlation, that fact counts significantly against the theory. Philosophical theories that imply that we have knowledge of non-causal mind-independent facts are especially prone to this objection. Prominent examples of such theories are mathematical Platonism, robust normative realism and modal realism. It is sometimes thought that theists can easily respond to this sort of challenge and that theism therefore has an epistemic advantage over atheism. In this paper, (...) I will argue that, contrary to widespread thought, some versions of theism only push the challenge one step further and thus are in no better position than atheism. (shrink)
