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.

A long-standing family of worries about moral realism focuses on its implications for moral epistemology. The underlying concern is that if moral truths have the nature that realists believe, it is hard to see how we could know what they are. This objection may be called the “argument from skepticism” against moral realism. Realists have primarily responded to this argument by presenting accounts of how we could acquire knowledge of moral truths that are consistent with realist assumptions about their (...) nature. Less time has been spent, however, on the question of why it would be a problem for moral realism if it leads to skepticism in the first place, and on the related question of which skeptical conclusions it would be problematic for realists to simply accept. This paper considers several answers to these questions, thereby distinguishing a number of versions of the argument from skepticism, and discusses their prospects. (shrink)

Inquiring minds want to know, not merely to believe or even to believe truly. They want knowledge of “the facts,” at least the facts in a relevant domain. Epistemology thus investigates and elucidates what inquiring minds want. So, epistemology is valuable to inquiring minds, whatever their domains of interest. A person might settle for true belief and remain lazily indifferent to knowledge, but this would be odd indeed. Inquiring minds seek something better grounded than true belief based just on lucky (...) guesswork, for example. They want true beliefs grounded in adequate evidence, if only to avoid the vicissitudes of ungrounded belief. (shrink)

The focus of this paper is the following claim: as a purely conceptual matter, the moral truths could be pretty much anything, and we should assume this in assessing our reliability at grasping moral truths. This claim, which I call No Content, plays a key role in an important skeptical argument against realist moral knowledge – the Normative Lottery Argument. In this paper, I argue that moral realists can, and should, reject No Content. My argument centers on the idea of (...) practical intelligibility. I explore different aspects of practical intelligibility, and I argue that such intelligibility sets a constraint on the possibilities we should consider when assessing our reliability at grasping moral truths.

The Cartesian skeptic’s strategy is to tell a story about the world that is entirely consistent with all of the empirical evidence that we do, or can, have, but according to which many or all of our ordinary beliefs are false. He then suggests that, since we cannot show that his story is false, we ought to surrender those beliefs. In this paper I offer a decision-theoretic response to skepticism. Say that a cognitive attitude is a propositional attitude that (...) may be true or false. I argue that rejecting the skeptic’s story, and so retaining our ordinary opinions, will yield for us true cognitive attitudes, no matter whether the skeptic’s story is true or false, and that the best any alternative can do is yield no cognitive attitudes at all. Hence, it is rational to retain our ordinary opinions. One may be concerned that I can maintain this surprising conclusion because the cognitive attitudes at issue are not real beliefs, and do not represent the real world. I conclude the paper by arguing that this concern is misplaced. (shrink)

In this paper, I discuss two different metaethical challenges based on population ethical impossibility results. According to the anti-realist challenge, the results pose a serious threat to the existence of objective moral facts. According to the skeptical challenge, the results pose a serious threat to the reliability of our moral intuitions. My aim is to systematically explore and evaluate these challenges. In addition to clarifying the issues, I argue that population ethical impossibility results do not in fact support any anti-realist (...) or skeptical conclusions. (shrink)

The purpose of the paper is to cast doubt on the alleged intuitive or natural character of the skeptical argument about the external world. In §1, we examine a version of the skeptical argument based on the epistemic closure principle and the indifference principle. In §2, in order to deepen the view defended by Michael Williams, we offer a novel examination of the Cartesian skeptical argumentation to show that it is clear that the alleged naturalness claimed by the skeptic is (...) nowhere to be found in two arguments which can be found in such argumentative strategy; moreover, to reach her conclusion, the skeptic needs to commit to epistemological realism, namely, the claim that each of our beliefs belongs to an epistemological hierarchy based solely on its content. In §3, based on arguments inspired by Wittgenstein, contra epistemological realism, we show how each belief has a justificatory role based on its context. (shrink)

For several decades, renewed interest in the connection between perception and knowledge has sustained a robust debate over external world skepticism. Recently, however, a growing consensus claims the skeptical challenge has been substantially met, and that realism in some robust form has emerged a clear victor. I invite us to rethink this consensus in a two-part response. The first forges a temporary alliance with skepticism against prominent forms of contemporary realism. That these fail to rebuff ews bolsters Barry (...) Stroud’s call for a new paradigm of objectivity. In the second part I sketch such a paradigm based upon a transactional interpretation of John Dewey’s pragmatism, and indicate its resilience to skeptical attacks. (shrink)

In the discipline of international relations there are contending general theories or theoretical perspectives. Realism, also known as political realism, is a view of international politics that stresses its competitive and conflictual side. It is usually contrasted with idealism or liberalism, which tends to emphasize cooperation. Realists consider the principal actors in the international arena to be states, which are concerned with their own security, act in pursuit of their own national interests, and struggle for power. The negative side of (...) the realists’ emphasis on power and selfinterest is often their skepticism regarding the relevance of ethical norms to relations among states. National politics is the realm of authority and law, whereas international politics, they sometimes claim, is a sphere without justice, characterized by active or potential conflict among states. Not all realists, however, deny the presence of ethics in international relations. The article presents a comprehensive picture of political realism. -/- Korab-Karpowicz, W.

A 1% skeptic is someone who has about a 99% credence in non-skeptical realism and about a 1% credence in the disjunction of all radically skeptical scenarios combined. The first half of this essay defends the epistemic rationality of 1% skepticism, appealing to dream skepticism, simulation skepticism, cosmological skepticism, and wildcard skepticism. The second half of the essay explores the practical behavioral consequences of 1% skepticism, arguing that 1% skepticism need not be behaviorally (...) inert. (shrink)

Skepticism has been (and remains) a central concern of the theory of knowledge. Indeed, some philosophers think that, without the problem of skepticism, we would not know what to make of the idea of distinctively philosophical theories of knowledge. However, a philosopher who thinks along these lines is likely to have in mind a rather special form of skepticism. Let us call it philosophical skepticism. Philosophical skepticism has a long history. Indeed, it is almost coeval (...) with systematic philosophy itself. (shrink)

Neo-Kantian constructivism aspires to respond to moral skepticism by compelling agents to act morally on pain of irrationality. According to Christine Korsgaard, a leading proponent of constructivism, we construct all reasons for action by following correct deliberative procedures. But if we follow these procedures we will find that we only have reasons to act in morally permissible ways. Thus, we can show the skeptic that he is rationally constrained to act morally. Unfortunately, as I argue in my first chapter, (...) this strong response to moral skepticism renders deliberate immoral action unintelligible. This result is problematic since we often do interpret ourselves and others as deliberately choosing to do wrong. I further suggest that this problem follows from central commitments of Korsgaard’s constructivism, so that any adequate account of immoral action must abandon constructivist metaethics in favor of moral realism, a suggestion reinforced by the argument of my second chapter. There, I call attention to Kant’s solution to a similar problem in his own account of morality. I argue that Korsgaard’s constructivist commitments prevent her from embracing Kant’s solution. I proceed in my third chapter to argue that there is a further tension between Korsgaard’s response to moral skepticism and her work in non-ideal theory. In particular, Korsgaard maintains that, when confronted with injustice, the virtuous person may have reason to do what is wrong in the name of morality. She thus relies on the assumption that one can deliberately do wrong. I argue that this assumption undermines the response to skepticism that motivated Korsgaard’s constructivism in the first place. But despite the problems with constructivism, we may worry that moral realism fails to offer an adequate response to moral skepticism. Indeed, Korsgaard rejects realism in part because she believes that realists simply refuse to respond to moral skepticism. I thus conclude by arguing that moral realists can offer adequate responses to moral skepticism. In fact, I believe Korsgaard’s response is no more effective than those suggested by some moral realists. (shrink)

I take up two questions raised by Luz Christopher Seiberth's meticulous reconstruction of Wilfrid Sellars's theory of intentionality. The first is whether we should regard Sellars as a transcendental phenomenalist in the most interesting sense of the term: as denying that even an ideally adequate conceptual structure would enable us to represent worldly objects as they are in themselves. I agree with Seiberth that the answer is probably yes, but I suggest that this is due not to Sellars's rejection of (...) the Myth of the Given or appeal to image-models (as Seiberth maintains), but to his view of modality as categorial but as absent from the world an sich. The second is whether, as Richard Rorty complained, Sellars's appeal to picturing lands his theory of intentionality in intractable skepticism. Pace Seiberth, I argue that the transcendental role of picturing does not mitigate this problem, and I suggest that Sellars's most fruitful resource for doing so is not his semantic externalism, but his purely pragmatic response to skepticism.

In response to Ari Armstrong's essay, "A Direct Realist's Challenge to Skepticism," Huemer defends his views on two issues concerning the nature of perception, against the Objectivist position: First, he argues that perceptual experiences have propositional but nonconceptual content; second, he argues that in perceptual illusions, the senses misrepresent their objects. He finds that the Objectivist view that perception cannot misrepresent because it lacks propositional content not only is absurd but opens the door to philosophical skepticism.

In this paper I argue for the importance of treating mental experience on its own terms. In defense of “experiential realism” I offer a critique of modern psychology’s all-too-frequent attempts to effect an objectification and quantification of personal subjectivity. The question is “What can we learn about experiential reality from indices that, in the service of scientific objectification, transform the qualitative properties of experience into quantitative indices?” I conclude that such treatment is neither necessary for realizing, nor sufficient for capturing, (...) subjectively given states (such as perception, pain, imagery, fear, thought, memory) – that is, for understanding many of the principle objects of psychological inquiry. A “science of mind” that approaches its subject matter from a third-person perspective should, I contend, be treated with a healthy amount of informed skepticism. (shrink)

I defend external world realism. I assume that the principle of inference to the best explanation is justified: roughly, a hypothesis that provides a better explanation of the total evidence is more probable than one that does not. I argue that the existence of a world of spatial objects provides a systematic explanation of the spatial contents of visual experience, and that it provides a better explanation than traditional skeptical hypotheses. This paper thus pursues the explanationist strategy of Laurence BonJour (...) and Jonathan Vogel. It is an improved, more compelling defense, for at least two reasons. First, the attention to spatial properties, and in particular to what I call perspectival projections, makes the explanatory power of the realist hypothesis much more vivid and concrete. Second, the argument preserves and elucidates much that seems correct in the explanationist arguments others have offered while avoiding significant problems and shortcomings. (shrink)

This chapter offers a new interpretation of Nietzsche’s argument for moral skepticism, 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. 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 claims 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 chapter concludes by considering various attempts to defuse this abductive argument for scepticism. (shrink)

A 1% skeptic is someone who has about a 99% credence in non-skeptical realism and about a 1% credence that some radically skeptical scenario obtains.

The second half of the essay explores the practical behavioral consequences of 1% skepticism.

Within much contemporary epistemology, Kant’s response to skepticism has come to be epitomized by an appeal to transcendental arguments. This form of argument is said to provide a distinctively Kantian way of dealing with the skeptic, by showing that what the skeptic questions is in fact a condition for her being able to raise that question in the first place, if she is to have language, thoughts, or experiences at all. In this way, it is hoped, the game played (...) by the skeptic can be turned against herself.1 At the same time, however, this appeal to transcendental arguments is also widely felt to show what is wrong with Kant’s response to skepticism: for, it is suggested, such arguments can only be made to work against the background of his transcendental idealism. As we shall see, what this doctrine amounts to is much disputed; but as with any form of idealism, the worry is that it means compromising the very realism and objectivity we want to defend against skepticism in the first place, so that the price for adopting this Kantian strategy appears too high—the cure of using transcendental arguments in conjunction with transcendental idealism is almost as bad as the disease.2 Faced with this difficulty, two kinds of response have been canvassed. On the first, it is accepted that transcendental arguments do require a commitment to the wider philosophical framework of transcendental idealism, but it is claimed that this framework can and should be defended against the suggestion that it is itself ‘‘quasi-skeptical.’’ On the second, transcendental idealism is indeed abandoned as wrongheaded, but it is held that Kant’s transcendental arguments can be made to..

In _Realistic Rationalism_, Jerrold J. Katz develops a new philosophical position integrating realism and rationalism. Realism here means that the objects of study in mathematics and other formal sciences are abstract; rationalism means that our knowledge of them is not empirical. Katz uses this position to meet the principal challenges to realism. In exposing the flaws in criticisms of the antirealists, he shows that realists can explain knowledge of abstract objects without supposing we have causal contact with them, that numbers (...) are determinate objects, and that the standard counterexamples to the abstract/concrete distinction have no force. Generalizing the account of knowledge used to meet the challenges to realism, he develops a rationalist and non-naturalist account of philosophical knowledge and argues that it is preferable to contemporary naturalist and empiricist accounts. The book illuminates a wide range of philosophical issues, including the nature of necessity, the distinction between the formal and natural sciences, empiricist holism, the structure of ontology, and philosophical skepticism. Philosophers will use this fresh treatment of realism and rationalism as a starting point for new directions in their own research. (shrink)

Many philosophers have been attracted to a restricted version of the principle of indifference in the case of self-locating belief. Roughly speaking, this principle states that, within any given possible world, one should be indifferent between different hypotheses concerning who one is within that possible world, so long as those hypotheses are compatible with one’s evidence. My first goal is to defend a more precise version of this principle. After responding to several existing criticisms of such a principle, I argue (...) that existing formulations of the principle are crucially ambiguous, and I go on to defend a particular disambiguation of the principle. According to the disambiguation I defend, how we should apply this restricted principle of indifference sensitively depends on our background metaphysical beliefs. My second goal is to apply this disambiguated principle to classical skeptical problems in epistemology. In particular, I argue that Eternalism threatens to lead us to external world skepticism, and Modal Realism threatens to lead us to inductive skepticism. (shrink)

One of the most important and perennially debated philosophical questions is whether we can have knowledge of the external world. Butchvarov here considers whether and how skepticism with regard to such knowledge can be refuted or at least answered. He argues that only a direct realist view of perception has any hope of providing a compelling response to the skeptic and introduces the radical innovation that the direct object of perceptual, and even dreaming and hallucinatory, experience is always a (...) material object, but not necessarily one that actually exists. This leads him to a metaphysics in which reality is ultimately constructed by human decisions out of objects that are ontologically more basic but which cannot be said in themselves to be either real or unreal.

Michael WiIliams maintains that skepticism about the extemal worId is vitiated by a commitment to foundationalism and epistemological realism. (The latter is, approximately, the view that there is such a thing as knowledge of the extemal world in general, which the skeptic can take as a target). I argue that skepticism is not encumbered in the ways Williams supposes. What matters, first of all, is that we can’t perceive the difference between being in an ordinary environment and being (...) in the sort of situation the skeptic describes (e.g. having one’s brain manipulated by deceitful experimenters). This point can be upheld without embracing any substantial foundationalist tenet, such as the existence of basic beliefs, the availabiIity of something “given,” or the epistemic priority of experience.

Disagreement is a pervasive feature of human life whose skeptical implications have been emphasized particularly by the ancient Pyrrhonists and by contemporary moral skeptics. Although the connection between disagreement and skepticism is also a focus of analysis in the emerging and burgeoning area of epistemology concerned with the significance of controversy, it has arguably not received the full attention it deserves. The present volume explores for the first time the possible skeptical consequences of disagreement in different areas and from (...) different perspectives, with an emphasis in the current debate over the epistemic impact of disagreement. The thirteen new essays collected here examine the Pyrrhonian approach to disagreement and its relevance to the present epistemological discussions of the topic; the relationship between disagreement and moral realism and antirealism; disagreement-based skeptical arguments in contemporary epistemology; and disagreement and the possibility of philosophical knowledge and justified belief. Given the ever-growing interest in both the significance of disagreement and the challenge of skepticism, this volume makes a new contribution by conjugating two important trends in current philosophical research.

Sharon Street (2006) has argued that, given certain plausible evolutionary considerations, normative realism leads to normative skepticism. Street calls this ‘the Darwinian dilemma’. This paper considers the two most popular responses to the Darwinian dilemma and argues that both are problematic. According to the naturalist response, the evolutionary account of our normative dispositions reveals that there was selection for normative dispositions that were reliable with respect to normative truth. According to the minimalist response, the evolutionary account reveals that there (...) was selection of normative dispositions that were reliable with respect to normative truth. This paper argues that the minimalist response is in principle unacceptable, and that the naturalist response faces a very serious difficulty. (shrink)

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

Free will skepticism maintains that what we do, and the way we are, is ultimately the result of factors beyond our control and because of this we are never morally responsible for our actions in the basic desert sense—the sense that would make us truly deserving of praise and blame. In recent years, a number of contemporary philosophers have advanced and defended versions of free will skepticism, including Derk Pereboom (2001, 2014), Galen Strawson (2010), Neil Levy (2011), Bruce (...) Waller (2011, 2015), and myself (Caruso 2012, 2013, forthcoming). Critics, however, often complain that adopting such views would have dire consequences for ourselves, society, morality, meaning, and the law. They fear, for instance, that relinquishing belief in free will and basic desert moral responsibility would leave us unable to adequately deal with criminal behavior, increase anti-social conduct, and undermine meaning in life. -/- In response, free will skeptics argue that life without free will and basic desert moral responsibility would not be as destructive as many people believe (see, e.g., Pereboom 2001, 2014; Waller 2011, 2015; Caruso 2016, forthcoming). According to optimistic skeptics, prospects of finding meaning in life or of sustaining good interpersonal relationships, for instance, would not be threatened. And although retributivism and severe punishment, such as the death penalty, would be ruled out, incapacitation and rehabilitation programs would still be justified (see Pereboom 2001, 2013, 2014; Levy 2012; Caruso 2016; Pereboom and Caruso, forthcoming). In this paper, I attempt to extend this general optimism about the practical implications of free will skepticism to the question of creativity. -/- In Section I, I spell out the question of creativity and explain why it’s relevant to the problem of free will. In Section II, I identify three different conceptions of creativity and explain the practical concerns critics have with free will skepticism. In Section III, I distinguish between three different conceptions of moral responsibility and argue that at least two of them are consistent with free will skepticism. I further contend that forward-looking accounts of moral responsibility, which are perfectly consistent with free will skepticism, can justify calling agents to account for immoral behavior as well as providing encouragement for creative activities since these are important for moral and creative formation and development. I conclude in Section IV by arguing that relinquishing belief in free will and basic desert would not mean the death of creativity or our sense of achievement since important and realistic conceptions of both remain in place.

In Explaining Attitudes, Baker argues that we should treat our everyday practices as relevant to metaphysical debates, resulting in a stance of realism with respect to intentional explanations. In this chapter I will argue that if one is going to be a practical realist about anything, it should be the self, or subject of attention. I will use research on attention combined with the stance of practical realism to argue in favor of a substantive self. That is, I will present (...) an account of the self that directs and controls attention, in line with our everyday view of the self. I will contrast this account with what I call the “illusion view,” which presents the self and its apparent causal power in the case of attention as an illusion. My account of the self will make use of several of Baker's ideas, including non-reductive materialism and broad supervenience. (shrink)
