This article argues that introductory ethics classes can unwittingly create or confirm skeptical views toward morality. Introductory courses frequently include critical discussion of skeptical positions such as moral relativism and psychological egoism as a way to head off this unintended outcome. But this method of forestalling skepticism can have a residual (and unintended) skeptical effect. The problem calls for deeper pedagogical-cum-philosophical engagement with the underlying sources of skepticism. The paper provides examples of how to do this and explains the additional (...) benefits of teaching moral skepticism. (shrink)

Christine Korsgaard has argued recently that the thesis that reasons are "essentially public" undermines the distinction between agent-neutral and agent-relative reasons, thus refuting egoism by rejecting its commitment to the universal availability of agent-relative reasons. I conclude that Korsgaard's invocation of the essential publicity of reasons trades on ambiguities concerning the "sharing" of reasons and so does not refute egoism and does not ground moral normativity. Her account of the publicity of reasons shows that solipsism is incoherent, but the egoist (...) need not be a solipsist, nor is she an incompetent user of moral language or the language of reasons.

It is commonly suggested that evolutionary considerations generate an epistemological challenge for moral realism. At first approximation, the challenge for the moral realist is to explain our having many true moral beliefs, given that those beliefs are the products of evolutionary forces that would be indifferent to the moral truth. An important question surrounding this challenge is the extent to which it generalizes. In particular, it is of interest whether the Evolutionary Challenge for moral realism is equally a challenge for (...) mathematical realism. It is widely thought not to be. In this paper, I argue that the Evolutionary Challenge for moral realism is equally a challenge for mathematical realism. Along the way, I substantially clarify the Evolutionary Challenge, discuss its relation to more familiar epistemological challenges, and broach a number of foundational issues in metaphysics. The paper should be of interest to ethicists because it places pressure on anyone who rejects moral realism on the basis of the Evolutionary Challenge to reject mathematical realism as well. And the paper should be of interest to philosophers of mathematics because it presents a new epistemological challenge for mathematical realism that bears, I argue, no simple relation to Paul Benacerraf's familiar challenge.

I first argue that there are many true claims of the form: x-ing would be morally required, if anything is. I then explain why the following conditional-type is true: If x-ing would be morally required, if anything is, then x-ing is actually morally required. These results allow us to construct valid proofs for the existence of some substantive moral facts—proofs that some particular acts really are morally required. Most importantly, none of my argumentation presupposes any substantive moral claim; I use (...) only plausible claims that most moral skeptics and error theorists can and do accept. The final section diagnoses why my arguments work. Here, I offer an explanation for the supervenience of the moral on the non-moral that may help those worried that the strategy is a sophisticated trick. I conclude by considering two objections. In replying to these objections, I explain why the strategy may allow us to demonstrate more than “obvious” moral truths, and why it may also address a stronger version of error theory, according to which, moral truths are not possible.

This thesis sets out an argument in defence of moral objectivism. It takes Mackie as the critic of objectivism and it ends by proposing that the best defence of objectivism may be found in what I shall call Kantian intuitionism, which brings together elements of the intuitionism of Ross and a Kantian epistemology. The argument is fundamentally transcendental in form and it proceeds by first setting out what we intuitively believe, rejecting the sceptical attacks on those beliefs, and by then (...) proposing a theory that can legitimize what we already do believe. Chapter One sets out our intuitive understanding of morality: (1) that morality is cognitive, moral beliefs can be true or false; (2) that morality is real, we do not construct it; (3) that morality is rational, we can learn about it by rational investigation; and (4) that morality places us under an absolute constraint. The chapter ends by clarifying the nature of that absolute demand and by arguing that the critical idea within morality is the idea of duty. In Chapter Two Mackie’s sceptical attack on objectivism is examined. Four key arguments are identified: (1) that moral beliefs are relative to bfferent agents; (2) that morality is based upon on non-rational causes; (3) that the idea of moral properties or entities is too queer to be sustainable; and (4) that moral objectivism involves queer epistemological commitments. Essentially all of these arguments are shown to be ambiguous; however it is proposed that Mackie has an underlying epistemological and metaphysical theory, scientific empiricism, which is (a) hostile to objectivism and (b) a theory that many find attractive for reasons that are independent of morality. Chapter Three explores the nature of moral rationality and whether scientific empiricism can use the idea of reflective equilibrium to offer a reasonable account of moral rationality. It concludes that, while reflective equilibrium is a useful account of moral rationality, it cannot be effectively reconciled with scientific empiricism. In order to function effectively as a rational process, reflective equilibrium must be rationally constrained by our moral judgements and our moral principles. Chapter Four begins the process of exploring some alternative epistemologies and argues that the only account that remains true to objectivism and the needs of reflective equilibrium is the account of intuitionism proposed by Ross. However this account can be developed further by drawing upon number of Kantian ideas and using them to supplement Ross ’ s intuitionism. So Chapter Five draws upon a number of Kant's ideas, most notably some key notions from the Critique of Judgement. These ideas are: (1) that we possess a rational will that is subject to the Moral law and determined by practical reason; (2) that we possess a faculty of judgement which enables us to become aware of moral properties and (3) that these two faculties together with the third faculty of thought can function to constitute the moral understanding. Using these ideas the thesis explores whether they can serve to explain how intuitions can be rational and how objectivism can be justified. (shrink)

Skeptical theism contends that, due to our cognitive limitations, we cannot expect to be able to determine whether there are reasons which justify God’s permission of apparently unjustified evils. Because this is so, the existence of these evils does not constituted evidence against God’s existence. A common criticism is that the skeptical theist is implicitly committed to other, less palatable forms of skepticism, especially moral skepticism. I examine a recent defense against this charge mounted by Michael Bergmann. I point out (...) that the Bergmannian skeptical theist is unable to determine concerning any event or feature of the world whether that feature or event is good or evil all-things-considered. Because of this the skeptical theist must abandon any attempt to act in such a way that the world becomes better rather than worse as a result. These, I claim, are seriously skeptical conclusions, and should cause us to be skeptical about skeptical theism itself. (shrink)

Any metaethicist tempted to dismiss a defense of moral intuitionism as too flaky to merit serious attention should think twice. Ethical Intuitionism is a forceful, clear, original, and intelligent piece of philosophy, and Michael Huemer can be proud of his efforts. He proceeds by identifying an exhaustive list of five possible metaethical positions, then knocks down four until only his favored intuitionism remains. One of the advantages of any such “last man standing” strategy is that even the most hardened opponent (...) is likely to be cheering on the author at least a lot of the time: The noncognitivist will support the demolition of subjectivism, the naturalist will applaud the humbling of the noncognitivist, and so on. Speaking as a moral error theorist, I was myself nodding along as Huemer undermined first the noncognitivist, then the subjectivist, and then the reductive naturalist. Yet even here, where my sympathies lay firmly with Huemer’s negative conclusions, I could perceive avenues for reply against his charges. But I don’t at present have the luxury of space to speak in defense of those whom I would, on other occasions and on other grounds, myself attack. Let them tell their own tales. I remain more-or-less on Huemer’s side through the first four chapters, and it is not until he gets to the case against moral nihilism that my own favorite view comes under attack. Thus, for the remainder, I shall don my moral nihilist’s hat and speak against Huemer’s dismissal of that viewpoint. (shrink)

There is an ancient, yet still lively, debate in moral epistemology about the epistemic significance of disagreement. One of the important questions in that debate is whether, and to what extent, the prevalence and persistence of disagreement between our moral intuitions causes problems for those who seek to rely on intuitions in order to make moral decisions, issue moral judgments, and craft moral theories. Meanwhile, in general epistemology, there is a relatively young, and very lively, debate about the epistemic significance (...) of disagreement. A central question in that debate concerns peer disagreement: When I am confronted with an epistemic peer with whom I disagree, how should my confidence in my beliefs change (if at all)? The disagreement debate in moral epistemology has not been brought into much contact with the disagreement debate in general epistemology (though McGrath [2007] is an important exception). A purpose of this paper is to increase the area of contact between these two debates. In Section 1, I try to clarify the question I want to ask in this paper – this is the question whether we have any reasons to believe what I shall call “anti-intuitivism.” In Section 2, I argue that anti-intuitivism cannot be supported solely by investigating the mechanisms that produce our intuitions. In Section 3, I discuss an anti-intuitivist argument from disagreement which relies on the so-called “Equal Weight View.” In Section 4, I pause to clarify the notion of epistemic parity and to explain how it ought to be understood in the epistemology of moral intuition. In Section 5, I return to the anti-intuitivist argument from disagreement and explain how an apparently-vulnerable premise of that argument may be quite resilient. In Section 6, I introduce a novel objection against the Equal Weight View in order to show how I think we can successfully resist the anti-intuitivist argument from disagreement. (shrink)

This essay offers a new interpretation of Nietzsche's argument for moral skepticism (i.e., the metaphysical thesis that there do not exist any objective moral properties or facts), an argument that should be of independent philosophical interest as well. On this account, Nietzsche offers a version of the argument from moral disagreement, but, unlike familiar varieties, it does not purport to exploit anthropological reports about the moral views of exotic cultures, or even garden-variety conflicting moral intuitions about concrete cases. Nietzsche, instead, (...) calls attention to the single most important and embarrassing fact about the history of moral theorizing by philosophers over two millennia: namely, that no rational consensus has been secured on any substantive, foundational proposition about morality. Persistent and apparently intractable disagreement on foundational questions, of course, distinguishes moral theory from inquiry in the sciences and mathematics (perhaps in kind, certainly in degree). According to Nietzsche, the best explanation for this disagreement is that, even though moral skepticism is true, philosophers can still construct valid dialectical justifications for moral propositions because the premises of different justifications will answer to the psychological needs of at least some philosophers and thus be deemed true by some of them. The essay concludes by considering various attempts to defuse this abductive argument for skepticism based on moral disagreement and by addressing the question whether the argument "proves too much," that is, whether it might entail an implausible skepticism about a wide range of topics about which there is philosophical disagreement.

Julia Annas has affirmed that the kind of modern moral skepticism which denies the existence of objective moral values rests upon a contrast between morality and some other system of beliefs about the world which is not called into doubt. Richard Bett, on the other hand, has argued that the existence of such a contrast is not a necessary condition for espousing that kind of moral skepticism. My purpose in this paper is to show that Bett fails to make a (...) good case against Annas’ thesis. To accomplish this, it will be helpful to consider the Pyrrhonean attitude towards morality as expounded in Sextus Empiricus’ work. (shrink)

Skeptical theism claims that the probability of a perfect God’s existence isn’t at all reduced by our failure to see how such a God could allow the horrific suffering that occurs in our world. Given our finite grasp of the realm of value, skeptical theists argue, it shouldn’t surprise us that we fail to see the reasons that justify God in allowing such suffering, and thus our failure to see those reasons is no evidence against God’s existence or perfection. Critics (...) object that skeptical theism implies a degree of moral skepticism that even skeptical theists will find objectionable and that it undermines moral obligations that even skeptical theists will want to preserve. I discuss a version of the first objection and defend a version of the second. (shrink)

In this paper, I develop a neglected puzzle for the moral realist. I then canvass some potential responses. Although I endorse one response as the most promising of those I survey, my primary goal is to make vivid how formidable the puzzle is, as opposed to offering a definitive solution.

We are strongly inclined to believe in moral responsibility, that some human agents truly deserve moral praise or blame for some of their actions. However, recent philosophical discussion has put this natural belief in the reality of moral responsibility under suspicion. There are important reasons to think that moral responsibility is incompatible with both determinism and indeterminism, possibly rendering moral responsibility an impossibility. This book lays out the major arguments for skepticism about moral responsibility and subjects them to sustained and (...) penetrating critical analysis. Moral Responsibility lays out the intricate dialectic involved in these issues in a helpful and accessible way. The book goes on to suggest a way in which skepticism can be avoided, arguing that an excessive pre-eminence given to the will might lie at the root of skepticism of moral responsibility. Carlos Moya offers an alternative to skepticism, showing how a cognitive approach to moral responsibility which stresses the importance of belief would rescue our natural and centrally important faith in the reality of moral responsibility.

Walter Sinnott-Armstrong's recent defense of moral skepticism raises the debate to a new level, but I argue that it is unsatisfactory because of problems with its assumption of global skepticism, with its use of the Skeptical Hypothesis Argument, and with its use of the idea of contrast classes and the correlative distinction between "everyday" justification and "philosophical" justification. I draw on Chisholm's treatment of the Problem of the Criterion to show that my claim that I know that, e.g., baby-torture is (...) wrong, is no more question-begging than Sinnott-Armstrong's denial that I know this.

I argue that the answer is affirmative, pace Oppy.

Some evidential arguments from evil rely on an inference of the following sort: ?If, after thinking hard, we can't think of any God-justifying reason for permitting some horrific evil then it is likely that there is no such reason?. Sceptical theists, us included, say that this inference is not a good one and that evidential arguments from evil that depend on it are, as a result, unsound. Michael Almeida and Graham Oppy have argued (in a previous issue of this journal) (...) that Michael Bergmann's way of developing the sceptical theist response to such arguments fails because it commits those who endorse it to a sort of scepticism that undermines ordinary moral practice. In this paper, we defend Bergmann's sceptical theist response against this charge. (shrink)

Several theists have adopted a position known as ‘sceptical theism’, according to which God is justified in allowing suffering, but the justification is often beyond human comprehension. A problem for sceptical theism is that if there are unknown justifications for suffering, then we cannot know whether it is right for a human being to relieve suffering. After examining several proposed solutions to this problem, I conclude that one who is committed to a revealed religion has a simpler and (...) more effective solution. In particular, according to traditional Judaism, God has permitted us, indeed commanded us, to relieve suffering, so we know that it is right for us to do so. I further show how God's command, according to Judaism, that we save lives provides an answer to an analogous argument put forward by David Hume. Thus, revealed theistic religions can sometimes solve problems more effectively than theism alone. (Published Online January 15 2007). (shrink)

: Moral-theory skepticism not an option in any sort of thinking that could actually be used in resolving dilemmas in applied ethics, since its characteristic doctrines entail positions that in practice often will lead to a kind of paralysis in moral reasoning, where persons faced with having to decide what to do in particularly difficult cases are unable to rule out the most implausible conclusions. Moral-theory skepticism thus makes it difficult to formulate decision-making procedures that will provide guidance in action (...) and, so, seems not to succeed as a fully coherent account of moral reasoning. (shrink)

Natural disasters would seem to constitute evidence against the existence of God, for, on the face of things, it is mysterious why a completely good and all-powerful God would allow the sort of suffering we see from earthquakes, diseases, and the like. The skeptical theist replies that we should not expect to be able to understand God’s ways, and thus we should not regard it as surprising or mysterious that God would allow natural evil. I argue that skeptical theism leads (...) to moral paralysis: accepting skeptical theism would undermine our ability to make any moral judgments whatsoever. Second, and more briefly, I argue that skeptical theism would undercut our ability to accept any form of the argument from design, including recent approaches based on fine-tuning. (shrink)

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

Thomas Nagel has proposed that the existence of moral luck mandates a general attitude of skepticism in ethics. One popular way of arguing against Nagel’s claim is to insist that the phenomenon of moral luck itself is an illusion , in the sense that situations in which it seems to occur may be plausibly re-described so as to show that agents need not be held responsible for the unlucky outcomes of their actions. Here I argue that this strategy for explaining (...) away moral luck fails because it does not take account of the fact that agents in morally unlucky circumstances are uniformly subject to a very specific type of epistemic obligation. I then proceed to sketch out an alternative strategy for blocking the inference to skepticism, one that makes use of the distinctive explanatory resources provided by epistemic virtue theory. Key Words: moral luck • moral skepticism • Thomas Nagel • virtue epistemology • Linda Zagzebski. (shrink)

My book, Moral Skepticisms, is intended to serve as an introduction to moral epistemology as well as a development of my own moral epistemology. Hence, my opening chapter surveys the field of moral epistemology and the varieties of moral scepticism. The main lesson is that we should stop arguing about moral scepticism in general, because there are too many kinds that differ in too many important details.

I very much appreciate the time and care that Jamie Dreier and David McNaughton put into my book, Moral Skepticisms. Their comments raise profound and challenging issues that I cannot treat adequately here. All I can hope to do is point to some directions in which further discussion should proceed.

This précis summarizes my book Moral Skepticisms, with emphasis on my contrastivist analysis of justified moral belief and my Pyrrhonian moral scepticism based on meta-scepticism about relevance. This complex moral epistemology escapes a common paradox facing moral philosophers.

All contentious moral issues--from gay marriage to abortion and affirmative action--raise difficult questions about the justification of moral beliefs. How can we be justified in holding on to our own moral beliefs while recognizing that other intelligent people feel quite differently and that many moral beliefs are distorted by self-interest and by corrupt cultures? Even when almost everyone agrees--e.g. that experimental surgery without consent is immoral--can we know that such beliefs are true? If so, how? These profound questions lead to (...) fundamental issues about the nature of morality, language, metaphysics, justification, and knowledge. They also have tremendous practical importance in handling controversial moral questions in health care ethics, politics, law, and education. Sinnott-Armstrong here provides an extensive overview of these difficult subjects, looking at a wide variety of questions, including: Are any moral beliefs true? Are any justified? What is justified belief? The second half of the book explores various moral theories that have grappled with these issues, such as naturalism, normativism, intuitionism, and coherentism, all of which are attempts to answer moral skepticism. Sinnott-Armstrong argues that all these approaches fail to rule out moral nihilism--the view that nothing is really morally wrong or right, bad or good. Then he develops his own novel theory,--"moderate Pyrrhonian moral skepticism"--which concludes that some moral beliefs can be justified out of a modest contrast class but no moral beliefs can be justified out of an extreme contrast class. While explaining this original position and criticizing alternatives, Sinnott-Armstrong provides a wide-ranging survey of the epistemology of moral beliefs. (shrink)

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

Over the last decade there have been various attempts to use empirical data about people’s dispositions to choose to undermine various moral positions by arguing that our judgements about what to do are unreliable. Usually they are directed at non-consequentialists by consequentialists, but they have also been directed at all moral theories by skeptics about morality. Walter Sinnott-Armstrong has been one of the leading proponents of such general skepticism. He has argued that empirical results particularly undermine intuitionist moral epistemology. This (...) paper is an attempt to look at what intuitionists should say in response. Consider the following argument : Regress (R1) If any person S is ever justified in believing a normative claim that p then S must be able to infer p from other beliefs of S. (shrink)

I consider some themes and issues arising in recent work on moral responsibility, focusing on three recent books —Carlos Moya's Moral Responsibility, Al Mele's Free Will and Luck, and John Martin Fischer's My Way. I argue that these texts collectively suggest some difficulties with the way in which many issues are currently framed in the free will debates, including disputes about what constitutes compatibilism and incompatibilism and the relevance of intuitions and ordinary language for describing the metaphysics of free will (...) and moral responsibility. I also argue that each of the accounts raise more particular puzzles: it is unclear to what extent Moya’s account is properly an account of free will; Mele’s account raises questions about the significance of luck for compatibilist theories; and Fischer’s account of the value of responsibility as self-expression raises questions about the normative significance of moral responsibility.

This is a review of Christian Illies: The Grounds of Ethical Judgement: New Transcendental Arguments in Moral Philosophy (Clarendon Press, 2003).

In his early writings, Kant says that the solution to the puzzle of how morality can serve as a motivating force in human life is nothing less than the “philosophers’ stone.” In this dissertation I show that for years Kant searched for the philosophers’ stone in the concept of “respect” (Achtung), which he understood as the complex effect practical reason has on feeling. I sketch the history of that search in Chapters 1-2. In Chapter 3 I show that Kant’s analysis (...) in Groundwork I is incomplete because it does not explain how respect functions as a feeling in motivating choice. In Chapter 4 I argue that Kant’s subsequent attempt to sidestep this explanation in Groundwork III is unsuccessful, and that his position remains open to a skeptical threat. The argument in the second Critique, which I reconstruct in Chapters 5-6, overcomes this threat, and in doing so explains how the feeling of respect is both painful and pleasurable. -/- In the course of defending these claims, I provide an alternative reading of the shift in Kant’s ethical project from the Groundwork of 1785 to the second Critique of 1788 Against a common view in the literature, I argue that the shift does not concern the direction of Kant’s deduction (from freedom to morality, or morality to freedom); rather, it concerns his view of human sensibility and the resources he thinks we have to make our practical self-understanding intelligible. In the second Critique, I argue, Kant develops a novel approach to moral feeling from the perspective of the human agent; and this in turn clears room in his ethics for a new kind of a priori knowledge—namely, knowledge of what the activity of practical reason must feel like. By way of conclusion, I offer a few reasons for why the form of Kant’s argument in the second Critique is still relevant today, as it shows why we can only address moral skepticism from a first-personal perspective.
