Even though the lines of thought that support skepticism are extremely compelling, we're inclined to look for ways of blocking them because it appears to be an impossible view to accept, both for intellectual and practical reasons. One goal of this paper is to show that when skepticism is packaged right, it has few problematic implications (or at least fewer than is often assumed). It is, for example, compatible with all the following claims (when these are correctly interpreted).

My concern in this paper will be to explore and develop a version of nonsocratic skepticism about weakness of will. In my view, socratism is incorrect, but like Socrates, I think that the common understanding of weakness of will raises serious problems. Contrary to socratism, it is possible for a person knowingly to act contrary to his or her better judgment. But this description does not exhaust the common view of weakness. Also implicit in this view is the belief (...) that actions which are contrary to one's better judgment are free in the sense that the agent could have done otherwise. To take seriously the possibility of acting contrary to one's better judgment is at the same time to raise problems about the distinction between weakness and compulsion. I argue that the common view, according to which the differentiating feature is that the weak are able to conform their behavior to their practical judgments, is unjustified. Instead, I have proposed that weakness of will involves the failure to develop certain normal capacities of self-control, whereas compulsion involves desires which even the possession of such capacities would not enable one to resist.

We propose a model of motivated skepticism that helps explain when and why citizens are biased information processors. Two experimental studies explore how citizens evaluate arguments about affirmative action and gun control, finding strong evidence of a prior attitude effect such that attitudinally congruent arguments are evaluated as stronger than attitudinally incongruent arguments. When reading pro and con arguments, participants (Ps) counterargue the contrary arguments and uncritically accept supporting arguments, evidence of a disconfirmation bias. We also find a confirmation (...) bias—the seeking out of confirmatory evidence—when Ps are free to self-select the source of the arguments they read. Both the confirmation and disconfirmation biases lead to attitude polarization—the strengthening of t2 over t1 attitudes—especially among those with the strongest priors and highest levels of political sophistication. We conclude with a discussion of the normative implications of these findings for rational behavior in a democracy. (shrink)

The first part of this article discusses recent skepticism about character traits. The second describes various forms of virtue ethics as reactions to such skepticism. The philosopher J.-P. Sartre argued in the 1940s that character traits are pretenses, a view that the sociologist E. Goffman elaborated in the 1950s. Since then social psychologists have shown that attributions of character traits tend to be inaccurate through the ignoring of situational factors. (Personality psychology has tended to concentrate on people's conceptions (...) of personality and character rather than on the accuracy of these conceptions). Similarly, the political theorist R. Hardin has argued for situational explanations of bloody social disputes in the former Yugoslavia and in Africa, rather than explanations in terms of ethnic hatred for example. A version of virtue ethics might identify virtues as characteristics of acts rather than character traits, as traits consisting in actual regularities in behavior, or as robust dispositions that would manifest themselves also in counterfactual situations.

Radical skepticism endorses the extreme claim that large swaths of our ordinary beliefs, such as those produced by perception or memory, are irrational. The best arguments for such skepticism are, in their essentials, as familiar as a popular science fiction movie and yet even seasoned epistemologists continue to find them strangely seductive. Moreover, although most contemporary philosophers dismiss radical skepticism, they cannot agree on how best to respond to the challenge it presents. In the tradition of the (...) 18th century Scottish philosopher, Thomas Reid, Radical Skepticism and Epistemic Intuition joins this discussion by taking up four main tasks. First, it identifies the strongest arguments for radical skepticism, namely, underdetermination arguments, which emphasize the gap between our evidence and our ordinary beliefs based on that evidence. Second, it rejects all inferential or argument-based responses to radical skepticism, which aim to lay out good noncircular reasoning from the evidence on which we base our ordinary beliefs to the conclusion that those beliefs are probably true. Third, it develops a commonsense noninferential response to radical skepticism with two distinctive features: it consciously and extensively relies on epistemic intuitions, which are seemings about epistemic goods, such as knowledge and rationality, and it can be endorsed without difficulty by both internalists and externalists in epistemology. Fourth, and finally, it defends this commonsense epistemic-intuition-based response to radical skepticism against a variety of objections, including those connected with underdetermination worries, epistemic circularity, disagreement problems, experimental philosophy, and concerns about whether it engages skepticism in a sufficiently serious way.

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)

Memory skepticism denies our memory beliefs could have any notable epistemic good. One route to memory skepticism is to challenge memory’s epistemic trustworthiness, that is, its functioning in a way necessary for it to provide epistemic justification. In this paper we develop and respond to this challenge. It could threaten memory in such a way that we altogether lack doxastic attitudes. If it threatens memory in this way, then the challenge is importantly self-defeating. If it does not threaten (...) memory in this way, then the challenge leaves a foundation for an inference to the best explanation response, one we articulate and support. (shrink)

Pyrrhonism was one of the two main ancient skeptical traditions. In this second paper of the three‐part series devoted to ancient skepticism, I present and discuss some of the issues on Pyrrhonian skepticism which have been the focus of much attention in the recent literature. The topics to be addressed concern the outlooks of Pyrrho, Aenesidemus, and Sextus Empiricus.

The extreme skepticism that Hume’s dangerous dilemma introduces at the end of the first Book of the Treatise is deeply unsettling, in part because it seems to undermine Hume’s commitments to common life and philosophy, but also because Hume seems not to take its sweeping doubts seriously. He refuses to abandon his daily activities and philosophical pursuits, and he offers no clear account of what entitles him to sustain them. This paper explores a variety of tactics for addressing these (...) opposing elements of his thought. The most radical approach has Hume endorse nothing whatsoever in the Treatise, a maneuver that prevents any conflict between his doubts and his commitments from arising, though at a tremendous cost. A more charitable strategy allows Hume to speak with one consistent voice throughout the text by rejecting, repurposing, or restricting either his doubts or his commitments in a way that resolves the tension between them. Yet a third approach takes Hume to advance incompatible and irreconcilable positions but holds that the inconsistency in his thinking is not as destructive as it initially appears. None of the most promising ways of developing these proposals eliminates or satisfactorily eases the conflict in Hume’s work, and the enormous obstacles that they face give us little reason to hope for something better.

It is sometimes objected that we cannot adopt skepticism about moral responsibility, because the criminal justice system plays an indispensable social function. In this paper, I examine the implications of moral responsibility skepticism for the punishment of those convicted of crime, with special attention to recent arguments by Saul Smilansky. Smilansky claims that the skeptic is committed to fully compensating the incarcerated for their detention, and that this compensation would both be too costly to be practical and would (...) remove the deterrent function from incarceration. I argue that the skeptic is not committed to full compensation of the offender, and that the costs of such compensation would in any case be far smaller than Smilansky thinks. In fact, I claim, the costs of the criminal justice system to which the skeptic is committed might be very much lower than the costs – economic, social and moral – we currently pay as a consequence of our system of punishment.

Some of the best and most provocative work in recent philosophy has been on the ancient topic of scepticism. This book collects together the most important contributions to the recent discussion. It features essays by Anthony Brueckner, Keith DeRose, Fred Dretske, Graeme Forbes, Christopher Hill, David Lewis, Thomas Nagel, Robert Nozick, Hilary Putnam, Ernest Sosa, Gail Stine, Barry Stroud, Peter Unger, and Ted Warfield.

Talk of epistemic dilemmas is old talk in epistemology. But are there such things? In this paper I argue for modest skepticism about epistemic dilemmas. In order to do that, I first point out that not all normative conflicts constitute dilemmas: more needs to be the case. Second, I look into the moral dilemmas literature for inspiration and identify a set of conditions that need to be at work for a mere normative conflict to be a genuine normative dilemma. (...) Last, I argue that, while our epistemic life is peppered with epistemic normative conflict, epistemic dilemmas are much harder to find than we thought. (shrink)

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. As to “epistemological realism,” I find that Williams has offered no principled way to distinguish between ordinary chaIIenges to knowledge and skeptical challenges which, supposedly, have no cIaim on our concem.

Skeptical theism is a popular response to arguments from evil. Many hold that it undermines a key inference often used by such arguments. However, the case for skeptical theism is often kept at an intuitive level: no one has offered an explicit argument for the truth of skeptical theism. In this article, I aim to remedy this situation: I construct an explicit, rigorous argument for the truth of skeptical theism.

The ethics of the Zhuāngzi is distinctive for its valorization of psychological qualities such as open-mindedness, adaptability, and tolerance. The paper discusses how these qualities and their consequences for morality and politics relate to the text’s views onskepticism and value. Chad Hansen has argued that Zhuangist ethical views are motivated by skepticism about our ability to know a privileged scheme of action-guiding distinctions, which in turn is grounded in a form of relativism about such distinctions. Against this, Icontend that (...) the Zhuāngzi’s skepticism and its ethical stance jointly rest on a metaethical view of value as inherently plural, perspectival, heterogeneous, and contingent. This view provides grounds for moral consideration toward others and for political liberalism. It also explains how the psychological qualities valorized in the Zhuāngzi contribute to the value of our individual lives, by showing what their absence costs us. (shrink)

There is perhaps no more widely shared conviction in contemporary metaethics, even among those who hold otherwise divergent views, than that practical normativity must be capable of being naturalized (i.e., captured fully within a metaphysically naturalist worldview). My aim is to illuminate the central reasons for skepticism about this. While certain naturalizing projects are plausible for very limited purposes, it is unlikely that any can provide everything we might reasonably want from an account of goodness and badness, rightness and (...) wrongness, and unqualified reasons for acting—at least if we are unwilling to accept certain deflationary or bullet-biting moves. Some naturalizing views can be shown to fail outright to capture the relevant normative facts or properties, while others have more promise but can also be seen to have certain limitations and costs, failing to capture elements that some of us take to be important to an adequate theory of practical normativity. There are, of course, far more naturalizing moves than can be considered here, so the aim is not to establish the truth of nonnaturalism through a process of elimination. But I hope to say enough to bring out the central worries about naturalizing projects and to pose some challenges that apply more widely, with the aim of showing that ethical nonnaturalism remains an attractive and well-motivated option at least for those of us who reject both nihilism and various forms of ethical deflation.

Ideally, our account of knowledge would help us to understand the appeal of (and flaws in) skepticism,2 while remaining consistent with our ‘intuitions,' and supporting epistemic principles that seem eminently plausible. Of course, we don't always get what we want; we may not be able to move from intuitions and principles to an account that fully squares with them. As a last resort, we may have to move in the other direction, and give up intuitions or principles that are (...) undermined by an otherwise compelling account of knowledge, so as to achieve ‘reflective equilibrium.'3 But last resorts come last.

This paper analyzes the apraxia argument in Cicero’s Academica. It proposes that the argument assumes two modes: the evidential mode maintains that skepticism is false, while the pragmatic claims that it is disadvantageous. The paper then develops a tension between the two modes, and concludes by exploring some differences between ancient and contemporary skepticism.

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)

Radical skepticism is the view that we know nothing or at least next to nothing. Nearly no one actually believes that skepticism is true. Yet it has remained a serious topic of discussion for millennia and it looms large in popular culture. What explains its persistent and widespread appeal? How does the skeptic get us to doubt what we ordinarily take ourselves to know? I present evidence from two experiments that classic skeptical arguments gain potency from an interaction (...) between two factors. First, people evaluate inferential belief more harshly than perceptual belief. Second, people evaluate inferential belief more harshly when its content is negative (i.e., that something is not the case) than when it is positive (i.e., that something is the case). It just so happens that potent skeptical arguments tend to focus our attention on negative inferential beliefs, and we are especially prone to doubt that such beliefs count as knowledge. That is, our cognitive evaluations are biased against this specific combination of source and content. The skeptic sows seeds of doubt by exploiting this feature of our psychology. (shrink)

Cartesian skepticism requires scenarios of massive deception to make its case. The inability to rule out such possibilities in which our beliefs about the external world are massively mistaken motivates the conclusion that we lack everyday knowledge. Some authors have emphasized that such scenarios are implausible. Others have instead claimed that scenarios are irrelevant to skepticism. If skepticism can make its case, they argue that scenarios of massive deception are not the way to do it. This thesis (...) possesses a distinct anti-sceptical weight. Deprived of its scenario, epistemological skepticism must find a different reason for it to be taken seriously, which might be a tall order. This paper defends the idea that scenarios do not constitute the essential element of the skeptical threat. However, it takes this result in the opposite direction. We aim to show that skepticism without scenarios constitutes a bigger and more legitimate philosophical problem than otherwise. Additionally, it also offers the possibility of achieving a unified understanding of skepticism that is so far lacking in contemporary epistemology, allowing us to better understand what can constitute a satisfactory anti-skeptical strategy.

Skepticism: From Antiquity to the Present is an authoritative and up-to-date survey of the entire history of skepticism. Divided chronologically into ancient, medieval, renaissance, modern, and contemporary periods, and featuring 50 specially-commissioned chapters from leading philosophers, this comprehensive volume is the first of its kind.

This book, first published in 2000, is about the nature of skeptical arguments and their role in philosophical inquiry. John Greco delineates three main theses: that a number of historically prominent skeptical arguments make no obvious mistake, and therefore cannot be easily dismissed; that the analysis of skeptical arguments is philosophically useful and important, and should therefore have a central place in the methodology of philosophy; and that taking skeptical arguments seriously requires us to adopt an externalist, reliabilist epistemology. Greco (...) argues that the importance of skeptical arguments is methodological. It is further argued that taking skeptical arguments seriously requires us to adopt a version of 'virtue epistemology', or a theory of knowledge that makes intellectual virtue central in the analysis of knowledge. The above methodology has consequences for moral and religious epistemology; in particular, a theory of moral perception is defended. (shrink)

This paper introduces Matraversian skepticism from aesthetics (i.e., there is no _cognitively_ interesting difference between our engagement with fiction versus our engagement with non-fiction) to debates in psychology and cognitive science on memory processing. I argue that the concept of ‘fiction’ has no place in our cognitive models of memory, neither in a specific category of memory, nor as a fact/fiction dimension. I propose a two-stage model of memory processing and explore the skeptical challenge that it poses to existing (...) accounts of the role of the concept of ‘fiction’ in models of memory. An important element of this challenge is the realization that remembering agents typically recognize a range of different kinds of non-fictional, non-believed memories, e.g., memories originating in lies, trickery, dreams, hallucinations, illusions, etc. (shrink)

How does trust operate under conditions of oppression? Little attention has been paid to how distrust may be both necessary and costly to its bearer. Distrust is clearly warranted under certain conditions, but do those conditions contribute to a reduction in one's overall well-being? More importantly, is there something about distrust itself (rather than the conditions that warrant it) that contributes to this reduction in well-being? In this essay, I explore these questions in depth. I explain what the costs of (...) distrust are and how they impede our well-being. I argue that the weakened development of trust through oppression has some important downstream consequences: namely, it requires the cultivation of skepticism as a virtue of distrust, which I argue should be included as one of Lisa Tessman's burdened virtues—those that are required for survival but that do not necessarily lead to the agent's flourishing.

Pinillos’ Why We Doubt presents a powerful critique of such global skeptical assertions as “I don’t know I am not a brain-in-a-vat (biv)” by introducing a cognitive mechanism that is sensitive to error possibilities and a Bayesian rule of rationality that this mechanism is designed to approximate. This multifaceted argument offers a novel counter to global skepticism, contending that our basis for believing such premises is underminable. In this work, we engage with Pinillos’ adoption of Bayesianism, questioning whether the (...) Bayesian principle that he invokes truly does fail to generate the verdict that we don’t we aren’t biv s, contrary to what Pinillos asserts. Furthermore, we argue that Pinillos’ empirical argument is not empirical enough; we need a lot more empirical work if we are going to counter global skepticism and win over neutral bystanders.

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.

In this paper, I examine the epistemological positions of Philo and Cleanthes in the Dialogues. I find that Philo's attitude towards skepticism mirrors that of the first Enquiry, most notably in its endorsement of mitigated skepticism, and its treatment of religious reasoning as distinctly discontinuous with science and philosophy. Meanwhile, Cleanthes's epistemological framework corresponds to that of the Treatise, most notably in its adoption of something like the Title Principle, and its treatment of some forms of religious reasoning (...) as broadly continuous with science and philosophy. It is not merely that the epistemological systems of the Treatise and Enquiry are echoed in Cleanthes's and Philo's positions respectively; these frameworks seem to clarify, provide a substantive basis for, and render more complete their somewhat piecemeal statements on this topic in the Dialogues. Thus, Philo's and Cleanthes's dispute is not limited to the theological, but extends to the epistemological. -/- . (shrink)

Skepticism about moral responsibility, or what is more commonly referred to as moral responsibility skepticism, refers to a family of views that all take seriously the possibility that human beings are never morally responsible for their actions in a particular but pervasive sense. This sense is typically set apart by the notion of basic desert and is defined in terms of the control in action needed for an agent to be truly deserving of blame and praise. Some moral (...) responsibility skeptics wholly reject this notion of moral responsibility because they believe it to be incoherent or impossible. Others maintain that, though possible, our best philosophical and scientific theories about the world provide strong and compelling reasons for adopting skepticism about moral responsibility. What all varieties of moral responsibility skepticism share, however, is the belief that the justification needed to ground basic desert moral responsibility and the practices associated with it—such as backward-looking praise and blame, punishment and reward (including retributive punishment), and the reactive attitudes of resentment and indignation—is not met. Versions of moral responsibility skepticism have historically been defended by Spinoza, Voltaire, Diderot, d’Holbach, Priestley, Schopenhauer, Nietzsche, Clarence Darrow, B.F. Skinner, and Paul Edwards, and more recently by Galen Strawson, Derk Pereboom, Bruce Waller, Neil Levy, Tamler Sommers, and Gregg D. Caruso. Critics of these views tend to focus both on the arguments for skepticism about moral responsibility and on the implications of such views. They worry that adopting such a view would have dire consequences for our interpersonal relationships, society, morality, meaning, and the law. They fear, for instance, that relinquishing belief in moral responsibility would undermine morality, leave us unable to adequately deal with criminal behavior, increase anti-social conduct, and destroy meaning in life. Optimistic skeptics, however, respond by arguing that life without free will and basic desert moral responsibility would not be as destructive as many people believe. These optimistic skeptics argue that prospects of finding meaning in life or of sustaining good interpersonal relationships, for instance, would not be threatened. They further maintain that morality and moral judgments would remain intact. And although retributivism and severe punishment, such as the death penalty, would be ruled out, they argue that the imposition of sanctions could serve purposes other than the punishment of the guilty—e.g., it can also be justified by its role in incapacitating, rehabilitating, and deterring offenders.

The truth of skepticism would be depressing and impractical. Our beliefs would be groundless, we would know nothing (or almost nothing) about the world around us, and epistemic success would likely be impossible. But do these negative consequences have any bearing on the truth of skepticism? According to many scholars, they do not. The impractical consequences of skepticism are typically regarded as orthogonal to its truth. For this reason, pragmatic resolutions to skepticism are regularly dismissed. I (...) will argue, however, that skepticism is implausible because it is impractical. In particular, skepticism is implausible because it goes against the point of epistemic evaluation. (shrink)

There is a long-standing tradition of questioning the viability and scientificity of first-person methods. Husserlian reflective methodology, in particular, has been challenged on the basis of its perceived inability to meet the standards of objectivity and reliability, leading to what has been called “phenomenological skepticism” ( Roy, 2007 ). In this article, I reassess this line of objection by outlining Daniel C. Dennett’s empirically driven skepticism and reconstructing his methodological arguments against Husserlian phenomenology. His ensuing phenomenological skepticism (...) is divided into strong skepticism and categorical and gradual versions of weak skepticism. Both strands of Dennett’s criticism are then countered by analyzing the key components of Husserl’s method of phenomenological reflection: epoché and transcendental reduction, intentional analysis, eidetic variation, and intersubjective validation. Laying out the basic features of phenomenological reflection serves two purposes. First, it undermines Dennett’s methodological arguments, which are based on the unfounded assumptions that Husserl is committed to introspection, methodological solipsism, the first-person-plural presumption, and the lone-wolf approach. Second, it shows how Husserl’s own methodology can alleviate the more justified empirical worries concerning overinterpretation, underdescription, and disagreement. Finally, I argue that gradual weak skepticism is the only plausible form of phenomenological skepticism and conclude that Husserlian methodology is well-equipped to combat it. (shrink)

Stephen Schiffer has argued that contextualist solutions to skepticism rest on an implausible "error theory" concerning our own semantic intentions. Similar arguments have recently been offered also by Thomas Hofweber and Patrick Rysiew. I attempt to show how contextualists can rebut these arguments. The kind of self-knowledge that contextualists are committed to denying us is not a kind of self-knowledge that we need, nor is it a kind of self-knowledge that we can plausibly be thought to possess.

External World Skepticism: The Deception of the Senses.

The Zhuangzi text deploys two epistemic themes to accomplish its ends of combatting human pretensions to know the world and to prompting us to rediscover the world through fresh eyes. To get us to shed our arrogant dispositions it applies a constructive skepticism to whatever it is that human beings claim to know. To point towards a more constructive relationship with Nature, it articulates the stance of being a mirror to nature. This essay will explain how the text does (...) this and relates its conceptions of skepticism and being as mirror to relevant contemporary science. (shrink)

Transcendental arguments offer a particularlypowerful strategy for combating skepticism. Such arguments, after all, attempt to show thata particular skepticism is not simply mistakenbut inconsistent or self-refuting. Whilethus tempting to philosophers struggling withskepticism of various sorts, the boldconclusions of these arguments have longrendered them suspicious in the eyes of many. In fact, in a famous paper from 1968 BarryStroud develops what is often taken to be adecisive case against transcendental argumentsin general.Recent work in the area of practical reason,however, suggests (...) that such arguments stillhave their defenders. Theorists such as JamesDreier and Christine Korsgaard have reliedexplicitly on transcendental arguments tojustify certain principles of practical reason. Can such arguments overcome Stroud's objection? In what follows, I argue that they can. However effective Stroud's general criticismmay be in other areas, it does not apply in therealm of practical reason. Nevertheless, thereare strict limits on how far transcendentalarguments can take us. In particular, despiteKorsgaard's efforts, they cannot succeed inestablishing a rational foundation formorality.

Is skeptical theism tenable once one acknowledges, as proponents of that view do, one's cognitive limitations vis-à-vis religious matters? In this article, I aim to answer that question both by examining the apparent radical skeptical implications of the skeptical component of skeptical theism and by comparing this view with fideism and Pyrrhonism, which also lay emphasis on our cognitive limitations. My ultimate purpose is to determine which of the three stances it makes more sense to adopt once the limitations of (...) human cognitive powers are recognized. (shrink)

A belief is debased when believing is given a basis that is not proper for knowledge, such as wishful thinking or superstition. The possibility of a debasing demon is the possibility of a maximally powerful agent who aims to prevent knowledge by debasing beliefs. Jonathan Schaffer contends that the debasing demon is a threat to all knowledge. Schaffer does not assess the strength of the skeptical challenge from debasing. It is argued here that debasing does not strengthen any case for (...) skepticism. A debasing demon is possible. We should acknowledge that our beliefs could have been debased, and that this could have been done in an introspectively undetectable way. But acknowledging this leaves us in a position to know that our apparent knowledge is genuine. It does not enhance any reason to think that we lack knowledge. (shrink)

The paper explores the anti-skeptical bearing of the kind of hinge epistemology I have developed in Extended Rationality. A Hinge Epistemology. It focuses, in particular, on the moderate account of perceptual justification, the constitutive response put forward against Humean skepticism, and the denial of the unconditional validity of the Closure Principle, which is key in rebutting Cartesian skepticism. Along the way, a comparison with Wittgenstein's own views in on Certainty and with the positions held by other prominent hinge (...) epistemologists, particularly Moyal-Sharrock, Pritchard and Wright, is provided.

The main causes of suicide and how suicide could and should be prevented are ongoing controversies in the scientific literature as well as in public media. In the bill on public health from 2008, the Swedish Parliament adopted an overarching “Vision Zero for Suicide” and nine strategies for suicide prevention. However, how the VZ should be interpreted in healthcare is unclear. The VZ has been criticized both from a philosophical perspective and against the background of clinical experience and alleged empirical (...) claims regarding the consequences of regulating suicide prevention. This study is part of a larger research project in medical ethics with the overarching aim to explore whether the VZ is ethically justifiable. The aim is to enrich the normative discussion by investigating empirically how the VZ is perceived in healthcare. Interviews based on a semi-structured interview guide were performed with 12 Swedish psychiatrists. The interviews were analysed with descriptive qualitative content analysis aiming for identifying perceptions of the Vision Zero for Suicide as well as arguments for and against it. Though most of the participants mentioned at least some potential benefit of the Vision Zero for Suicide, the overall impression was a predominant skepticism. Some participants focused on why they consider the VZ to be unachievable, while others focused more on its potential consequences and normative implications. The VZ was perceived to be impossible to realize, nonconstructive or potentially counterproductive, and undesirable because of potential conflicts with other values and interests of patients as well as the general public. There were also important notions of the VZ having negative consequences for the working conditions of psychiatrists in Sweden, in increasing their work-related anxiety and thwarting the patient-physician relationship.

Model-theoretic skepticism is a challenge to purported a priori mathematical knowledge. According to this challenge, elementary results from mathematical logic undermine our grasp of basic mathematical concepts such as finitude and countability. Despite generating rich discussion over the years, most philosophers don’t feel worried by model-theoretic skepticism, in part due to a number of notable anti-skeptical arguments. In this paper, I evaluate these arguments, and explore the question of whether (and to what extent) a skeptical threat remains.

Moore is a skeptic and Descartes is the ultimate social epistemologist. Jonathan Ichikawa misses this, and as a result he inherits the problems of insularity and exclusion that plague other Moorean skeptics.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 27, Number 1, April 2001, pp. 3-83 Moral Skepticism and Moral Naturalism in Hume's Treatise NICHOLAS L. STURGEON Section I I believe that David Hume's well-known remarks on is and ought in his Treatise of Human Nature (T 469-70)1 have been widely misunderstood, and that in consequence so has their relation to his apparent ethical naturalism and to his skepticism about the role of (...) reason in morality. My aim in this paper is to display their connection with these larger issues in Hume's work by placing them in a more illuminating light. Readers may wonder whether there is anything left to say about the passage containing these remarks; they may also share Barry Stroud's suspicion that the vast literature focused on this one paragraph has "given it an importance and point out of all proportion to its actual role in the text of the Treatise."2 But I have some new things to say. I agree, moreover, that many recent discussions, in projecting twentieth-century assumptions onto Hume's text, have accorded this passage the wrong sort of importance: that is part of what I want to correct. But getting clear about what Hume is saying here is, I shall argue, a way of moving familiar and obviously central questions about his views on morality into an unfamiliar but revealing focus. Hume's is-ought thesis is commonly, and I believe correctly, seen as an application of his more general skepticism about the capacity of reason to discover "moral distinctions." But that general skepticism is usually taken, in turn, to conflict with those many passages in which Hume Nicholas L. Sturgeon is Professor of Philosophy, Sage School of Philosophy, Cornell University, Ithaca, NY 14853-3201, USA. e-mail: [email protected] 4 Nicholas L. Sturgeon appears to say, in a reductive and naturalistic vein, that ascriptions of moral virtue and vice simply state certain empirical facts, facts about our own sentiments. My central thesis, however, is that Hume's view that there is a logical gap between is and ought is not merely consistent with his reductive naturalism, but actually depends on it. It is precisely because moral ascriptions state the facts that they do about our sentiments that no ought can be derived from an is and, a bit more generally, that reason is unable to discover moral distinctions. Hume's skepticism about reason in ethics depends, I shall argue, on his reductive ethical naturalism. This is not the usual understanding of Hume's views, and it will require careful explanation and defense. I shall proceed in several stages. My first step, in Section II, will be to argue that Hume's naturalism is at least consistent with his skepticism about reason, and in particular with his remarks about is and ought. I shall show this by focusing on a difficulty often taken to epitomize the conflict between these two strains in his thought: namely, that the paragraph containing these remarks (T 469-70: henceforth, the is-ought paragraph) and the one immediately preceding it (which I shall call the matter -of-fact paragraph (T 468-9)) appear, on their most natural readings, flatly to contradict one another.3 On the most common reading of the is-ought paragraph, it assumes the existence of two classes of statements, «-statements and oM^hr-statements, and declares that no member of the latter class can be derived entirely from members of the former. In the preceding paragraph, however, Hume appears in the guise of an ethical naturalist and subjectivist, and, if we take him at his word, simply equates a moral judgment with one asserting what he himself calls a "matter of fact," albeit a psychological fact about oneself: So that when you pronounce any action or character to be vicious, you mean nothing, but that from the constitution of your nature you have a feeling or sentiment of blame from the contemplation of it. (T 469) But, one supposes, if a moral assessment of an action or character is equivalent in meaning to a description of one's sentiments, then it can be derived from that description, and there...

According to global skepticism, we know nothing. According to local skepticism, we know nothing in some particular area or domain of discourse. Unlike their global counterparts, local skeptics think they can contain our invincible ignorance within limited bounds. I argue that they are mistaken. Local skepticism, particularly the kinds that most often get defended, cannot stay local: if there are domains whose truths we cannot know, then there must be claims outside those domains that we cannot know (...) even if they are true. My argument focuses on one popular form of local skepticism, ethical skepticism, but I believe that the argument generalizes to cover other forms as well. (shrink)
