This chapter focuses on the responses that proponents of virtue epistemology (VE) make to radical skepticism and particularly to two related forms of it, Pyrrhonian skepticism and the “underdetermination-based” argument, both of which have been receiving widening attention in recent debate. Section 1 of the chapter briefly articulates these two skeptical arguments and their interrelationship, while section 2 explains the close connection between a virtue-theoretic and a neo-Moorean response to them. In sections 3 and 4 I (...) advance arguments for improving the prospects of virtue-theoretic responses, sketching a particular version of VE that by recasting somewhat how we understand the “externalist turn in epistemology” also suggests ways of improving the adequacy of philosophical diagnoses and responses to skepticism.

My focus will be on two questions about Moore’s justification to believe the premises and the conclusion of the argument above. At stake is what makes it possible for our experiences to justify our beliefs, and what makes it possible for us to be justified in disbelieving skeptical..

A prominent response is that Cartesian skepticism is too Cartesian. It arises from outmoded views in epistemology and the philosophy of mind that we now properly reject. We can and should move on to other things. §2 takes up three broadly Cartesian themes: the epistemic priority of experience, under-determination, and the representative theory of perception. I challenge some common assumptions about these, and their connection to skepticism. §3 shows how skeptical arguments that emphasize causal considerations can avoid (...) some suspect Cartesian commitments. §4 explores the related idea that perceptual knowledge is what I call instrumental knowledge. Drawing on that connection, §5 examines a skeptical argument based on minimal assumptions, and explains why a Moorean response to it is unsatisfactory. The problem of skepticism is still with us, and it requires a substantive solution. (shrink)

Alexander Campbell once declared “a solemn league and covenant” between philosophy and common sense. Campbell’s pronouncement is representative of a broader trend in the Restorationist movement to look favorably on the common sense response to skepticism—a response originating in the work of Scottish philosopher and former minister Thomas Reid. I recount the tumultuous history between philosophy and common sense followed by the efforts of Campbell and Reid to reunite them. Turning to the present, I argue that an (...) epistemic principle known as phenomenal conservatism best embodies the core insights contained within Reid and Campbell's common sense response to skepticism. I finish by arguing for phenomenal conservatism. (shrink)

The Neo-Moorean response to the radical skeptical challenge boldly maintains that we can know we’re not the victims of radical skeptical hypotheses; accordingly, our everyday knowledge that would otherwise be threatened by our inability to rule out such hypotheses stands unthreatened. Given the leverage such an approach has against the skeptic from the very start, the Neo-Moorean line is an especially popular one; as we shall see, though, it faces several commonly overlooked problems. An initial problem is (...) that this particular brand of anti-skeptical strategy is available only to a theory of knowledge that will compromise itself to especially weak epistemic standards—indeed, standards as weak as our epistemic grounds are for accepting the denials of skeptical hypotheses. With this said, the aim here is to investigate whether the Neo-Moorean line could be advanced against the skeptic in a way that wouldn’t require wholesale lowering of epistemic standards. Unfortunately, as we’ll see, Sosa’s (2007; 2009) view as well as what I argue to be the other two most plausible contender-views for maintaining a Neo-Moorean line—Greco’s and Pritchard’s—run (for similar reasons) into dead ends. The way forward, I’ll argue, is to take on board a unique variety of robust virtue epistemology accord­ing to which knowledge is thought to be situated a certain way within a gradient balance between ability and luck.

Cartesian arguments for global skepticism about the external world start from the premise that we cannot know that we are not in a Cartesian scenario such as an evil-demon scenario, and infer that because most of our empirical beliefs are false in such a scenario, these beliefs do not constitute knowledge. Veridicalist responses to global skepticism respond that arguments fail because in Cartesian scenarios, many or most of our empirical beliefs are true. Some veridicalist responses have been motivated (...) using verificationism, externalism, and coherentism. I argue that a more powerful veridicalist response to global skepticism can be motivated by structuralism, on which physical entities are understood as those that play a certain structural role. I develop the structuralist response and address objections. (shrink)

I argue that some of the most prominent interpretations of Reid's response to skepticism marginalize a crucial aspect of his thought: namely, that our common sense beliefs meet whatever normative standards of rationality the skeptic might fairly demand of them. This should be seen as supplementary to reliabilist or proper functionalist interpretations of Reid, which often ignore this half of the story. I also show how Reid defends the rationality of believing first principles by appealing to their naturalness (...) and irresistibility. The resulting interpretation supplies Reid with a more satisfying and formidable response to the skeptic than interpretations currently offer. (shrink)

Rationalism, my target, says that in order to have perceptual knowledge, such as that your hand is making a fist, you must “antecedently” (or “independently”) know that skeptical scenarios don’t obtain, such as the skeptical scenario that you are in the Matrix. I motivate the specific form of Rationalism shared by, among others, White (Philos Stud 131:525–557, 2006) and Wright (Proc Aristot Soc Suppl Vol 78:167–212, 2004), which credits us with warrant to believe (or “accept”, in Wright’s terms) that our (...) senses are reliably veridical, where that warrant is one we enjoy by default, that is, without relying on any evidence or engaging in any positive argument. The problem with this form of Rationalism is that, even if you have default knowledge that your senses are reliable, this is not adequate to rule out every kind of skeptical scenario. The problem is created by one-off skeptical scenarios, scenarios that involve a highly reliable perceiver who, by a pure fluke, has a one-off, non-veridical experience. I claim you cannot infer that your present perceptual experience is veridical just on the basis of knowledge of your general reliability. More generally, if you infer that the present F is G, just on the basis of your knowledge that most Fs are Gs, this is what I call statistical inference, and, as I argue, statistical inference by itself does not generate knowledge. I defend this view of statistical inference against objections, including the objection that radical skepticism about our ordinary inductive knowledge will follow unless statistical inference generates knowledge.

In On Certainty, Wittgenstein formulates several criticisms against skepticism about our knowledge of the external world. My goal is to show that Wittgenstein does not here offer a convincing answer to the skeptical problem. First, I will present a strong version of the problem, understanding it as a paradoxical argument. In the second part, I will introduce and raise problems for two pragmatic responses against skepticism that appear in On Certainty. Finally, I will present some of Wittgenstein’s logical (...) criticisms against skepticism, which may initially be considered strong, because they seem to refute some skeptical assumptions. They concern Wittgenstein’s ideas that it is logically impossible to doubt and to be mistaken about Moorean propositions, and that these propositions don’t have a truth-value. But even these, I intend to show, do not really challenge skepticism, for they are not well grounded. (shrink)

I aim to offer a practical response to skepticism. I begin by surveying a family of responses to skepticism that I term “dogmatic” and argue that they are problematically evasive; they do not address what I take to be a question that is central to many skeptics: Why am I justified in maintaining some beliefs that fail to meet ordinary standards of doxastic evaluation? I then turn to a discussion of these standards of evaluation and to the (...) different kinds of doxastic value to which they appeal. While there is something good about having a true belief and something bad about having a false one, I argue the value of true beliefs is not intrinsic or final. Truth and knowledge are valuable because they contribute to both individual and collective flourishing. But if contributing to flourishing is what ultimately provides truth with its value, then we have discovered another doxastic value. I call this kind of doxastic value “practical.” The practical response addresses the skeptic’s question by claiming that some beliefs can be justified by appealing to their practical, rather than alethic, value. In fleshing out this practical response I contrast it both with dogmatic responses as well as some seemingly similar “practical” alternatives, namely Crispin Wright’s appeals to entitlements and Susanna Rinard’s “pragmatic skepticism.” I end by addressing some objections. (shrink)

The radical skeptic argues that I have no knowledge of things I ordinarily claim to know because I have no evidence for or against the possibility of being systematically fed illusions. Recent years have seen a surge of interest in pragmatic responses to skepticism inspired by C. S. Peirce. This essay challenges one such influential response and presents a better Peircean way to refute the skeptic. The account I develop holds that although I do not know whether the (...) skeptical hypothesis is true, I still know things I ordinarily claim to know. Although it will emerge that this reply appears similar to a classic contextualist response to radical skepticism, it avoids two central problems facing that response. (shrink)

This essay extends my side of a discussion begun earlier with Duncan Pritchard, the recent author of Epistemic Luck. Pritchard’s work contributes significantly to improving the “diagnostic appeal” of a neo-Moorean philosophical response to radical scepticism. While agreeing with Pritchard in many respects, the paper questions the need for his concession to the sceptic that the neo-Moorean is capable at best of recovering “‘brute’ externalist knowledge”. The paper discusses and directly responds to a dilemma that Pritchard poses (...) for virtue epistemologies (VE). It also takes issue with Pritchard’s “merely safety-based” alternative. Ultimately, however, the criticisms made here of Pritchard’s dilemma and its underlying contrast of “anti-luck” and “virtue” epistemologies are intended to help realize his own aspirations for a better diagnosis of radical scepticism to inform a still better neo-Moorean response. (shrink)

My main aim is to argue that most conceptions of doxastic agency do not respond to the skeptic’s challenge. I begin by considering some reasons for thinking that we are not doxastic agents. I then turn to a discussion of those who try to make sense of doxastic agency by appeal to belief’s reasons-responsive nature. What they end up calling agency is not robust enough to satisfy the challenge posed by the skeptics. To satisfy the skeptic, one needs to make (...) sense of the possibility of believing for nonevidential reasons. While this has been seen as an untenable view for both skeptics and anti-skeptics, I conclude by suggesting it is a position that has been too hastily dismissed. (shrink)

An objection that has been raised to the conciliatory stance on the epistemic significance of peer disagreement known as the Equal Weight View is that it is self-defeating, self-undermining, or self-refuting. The proponent of that view claims that equal weight should be given to all the parties to a peer dispute. Hence, if one of his epistemic peers defends the opposite view, he is required to give equal weight to the two rival views, thereby undermining his confidence in the correctness (...) of the Equal Weight View. It seems that the same objection could be leveled against those who claim to suspend judgment in the face of pervasive unresolvable disagreements, as do the Pyrrhonian skeptics. In this paper, I explore the kind of response to the objection that could be offered from a neo-Pyrrhonian perspective, with the aim of better understanding the intriguing character of Pyrrhonian skepticism.

A quite recent book casts the anthropologist Elizabeth Colson as a systems skeptic, with Max Gluckman attempting to counter her skepticism. In this paper, I offer clarifications of the skepticism and of the counter.

Pragmatist responses to skepticism about empirical justification have mostly been underwhelming, either presupposing implausible theses like relativism or anti-realism, or else showing our basic empirical beliefs to be merely psychologically inevitable rather than rationally warranted. In this paper I defend a better one: a modified version of an argument by Wilfrid Sellars that we are pragmatically warranted in accepting that our perceptual beliefs are likely to be true, since their likely truth is necessary for the satisfaction of our goal (...) of effective agency. On the version of the argument I defend, the great good for human life of control over our empirical circumstances renders our goal of effective agency reasonable. But only if our perceptual beliefs are likely to be true—and only if we accept that this is so, assuming it as a premise for inference and a guide for action—will the success of our actions be due to our effective agency, not mere luck. Since we’re warranted in taking the necessary means to our reasonable ends, we’re warranted in accepting that our perceptual beliefs are generally justified, and so that skepticism about empirical justification is false.

In the replies to my critics that follow I offer a more detailed account of the specific papers that they discuss or examine. The papers that they are especially concerned with are: “The Material World and Natural Religion in Hume’s Treatise” (Ryan) [Essay 3], “Hume’s Skepticism and the Problem of Atheism” (Fosl) [Essay 12], and “Hume’s Philosophy of Irreligion and the Myth of British Empiricism (Gautier) [Essay 16].

This paper aims for a more robust epistemological disjunctivism (ED) by offering on its behalf a new and better response to the ‘new evil genius’ problem. The first section articulates the ‘new evil genius challenge’ (NEG challenge) to ED, specifying its two components: the ‘first-order’ and ‘diagnostic’ problems for ED. The first-order problem challenges proponents of ED to offer some explanation of the intuition behind the thought that your radically deceived duplicate is no less justified than you are for (...) adopting her perceptual beliefs. In the second section, I argue that 'blamelessness' explanations are inadequate to the task and offer better explanations in their place—that of ‘trait-level virtue’ and ‘reasonability’. The diagnostic problem challenges proponents of ED to explain why it is that classical internalists disagree with them about how to interpret 'new evil genius' considerations. The proponent of ED owes some error theory. I tackle this problem in the third section, arguing that classical internalists overlook disjunctivist interpretations of new evil genius intuitions owing to a mistaken commitment to a ‘vindicatory’ explanation of perceptual knowledge.

I argue for three conclusions. First, responsibility skeptics are committed to the position that the criminal justice system should adopt a universal nonresponsibility excuse. Second, a universal nonresponsibility excuse would diminish some of our most deeply held values, further dehumanize criminals, exacerbate mass incarceration, and cause an even greater number of innocent people (nonwrongdoers) to be punished. Third, while Saul Smilansky's ‘illusionist’ response to responsibility skeptics – that even if responsibility skepticism is correct, society should maintain a responsibility‐realist/retributivist (...) criminal justice system – is generally compelling, it would not work if a majority of society were to convert, theoretically and psychologically, to responsibility skepticism. In this (highly improbable) scenario, and only in this (highly improbable) scenario, the criminal justice system would need to be reformed in such a way that it aligned with the majority's responsibility‐skeptical beliefs and attitudes.

In this paper, I aim to resolve the Frierson-Grenberg debate on the nature of Kant’s account of moral motivation that took place in the third issue of Con-textos Kantianos. In their respective interpretations, Frierson and Grenberg fail to accommodate the a priori status of moral feeling when incorporating it into Kant’s moral motivational structure. In response, I provide a novel transcendental interpretation – one that takes the a priori moral feeling both as an incentive of morality and as that (...) which conditions the possibility of morality in human agents. I argue that Kant developed the notion of moral feeling solely in order to resolve the problem of motivational skepticism concerning the moral law. Since this problem occurs as a part of Kant’s search for the supreme principle of morality, the notion of moral feeling becomes a part of both Kant’s moral motivational structure and his argument to justify the moral law.

Ethical naturalism is sometimes accused of problematic metaphysics or epistemology. Some argue that naturalists rely on concepts of ‘nature’ indefensible in the light of modern evolutionary biology. There is also an epistemological worry that has been raised recently that strong normative evaluation, such as meaning in human life, is empirically inaccessible or even in conflict with what we know in scientific contexts. While the critics have targeted Aristotelian and Neo-Aristotelian views, I will appeal to an argument from the Neo- Confucian (...) Zhu Xi as one potential way that we can respond to skeptics. If we can know that human beings are capable of moral goodness, and it is comprehensible for us to take moral goodness as a final or unifying goal of our lives, then we can respond to the skeptical objections which allege that we cannot sustain rich normative judgments about meaning in life in the face of scientific evidence.

A common response to radical skeptical challenges to our knowledge of the external world has been that there are explanatory reasons (e.g., simplicity, coherence, explanatory power, conservatism) for favoring commonsense explanations of our sensory experiences over skeptical explanations. Despite the degree of visibility this class of response has enjoyed, it has often been viewed with skepticism [sic] by the epistemological community because of concerns about the epistemic merits of explanatory reasoning. I argue that skeptical challenges that employ (...) skeptical hypotheses presuppose central explanationist tenets and that this fact should raise one’s estimation of the strength of explanationist responses to skepticism. (shrink)

In this paper, I attempt to show how Davidson’s anti-sceptical argument can respond to the closureRK-based radical scepticism. My approach will focus on the closureRK principle rather than the possibility that our beliefs could be massively wrong. I first review Davidson’s principle of charity and the triangulation argument, and then I extract his theory on content of a belief. According to this theory, content of a belief is determined by its typical cause and other relevant beliefs. With this constraint on (...) content, I argue that doubt must be local. Furthermore, since one cannot rationally believe that one’s commitment to the cause of beliefs could be false, our commitment to the denial of a sceptical hypothesis is not a knowledge-apt belief. Therefore, the closureRK principle is not applicable to rational evaluations of this commitment. As a result, the closureRK-based sceptical argument fails while the closureRK principle remains.

Moorean arguments are a popular and powerful way to engage highly revisionary philosophical views, such as nihilism about motion, time, truth, consciousness, causation, and various kinds of skepticism (e.g., external world, other minds, inductive, global). They take, as a premise, a highly plausible first-order claim (e.g., cars move, I ate breakfast before lunch, it’s true that some fish have gills) and conclude from it the falsity of the highly revisionary philosophical thesis. Moorean arguments can be used against (...) nihilists in ethics (error theorists), too. Recently, error theorists have recognized Moorean arguments as a powerful challenge and have tried to meet it. They’ve argued that moral Moorean premises seem highly credible to us, but aren’t, by offering various debunking explanations. These explanations all appeal to higher-order evidence—evidence of error in our reasoning. I argue that drawing attention to higher-order evidence is a welcome contribution from error theorists, but that the higher-order evidence actually counts further against error theoretic arguments—including their debunking explanations—and further in favor of Moorean arguments and the commonsense views they support. Along the way I answer a few prominent objections to Moorean arguments: that they are objectionably question-begging, rely on categorizing some facts as “Moorean Facts”, and that reports of one’s credence in a proposition bears no interesting relation to that proposition’s credibility.

The problem of philosophical skepticism relates to the difficulty involved in underwriting the claim that we know anything of spatio-temporal reality. It is often claimed, in fact, that proper philosophical scrutiny reveals quite the opposite from what common sense suggests. Knowledge of external reality is thought to be even quite obviously denied to us as a result of the alleged fact that we all fail to know that certain skeptical scenarios do not obtain. A skeptical scenario is one in (...) which we have neurological occurrences just like any normal situation in which we actually perceive spatio-temporal objects, but where we are deceived in some sense as a result of the manipulation of our brains from some outside source. In this work I attempt to address the problem of philosophical skepticism by claiming that most of us are able to come to know plenty about external reality, since we can come to realize that a certain philosophical theory of perception is correct. The theory I have in mind is what I call a non-cognitive theory of perception. According to this view, perceptual experience is defined by continuous, sensitive behavioral interaction with spatio-temporal objects of the appropriate size, shape, hardness, speed, etc. Knowing that this theory of perception is correct is equivalent to knowing that we know plenty about external reality. This is ultimately because by knowing that a non-cognitive theory of perception is true, we know that any skeptical scenario must fail to obtain. The structure of the work proceeds by first discussing the significance of the problem of philosophical skepticism in some detail. Chapter 1 lays out how the problem does indeed forcefully arise if it is conceded that we fail to know that the skeptical scenarios fail to obtain. Chapter 2 develops the sort of view of our epistemological situation that falls out of accepting without qualification that the problem exists. Chapter 3 examines and criticizes certain popular responses to the skeptical problem. The main goal of these first three preliminary chapters is to indicate that once it is admitted that we fail to know that the skeptical scenarios fail to obtain, the problem of philosophical skepticism forcefully presents itself. Chapter 4, however, attacks the idea that we fail to know that the skeptical scenarios fail to obtain. In this chapter I argue that this idea is wedded to the position that a certain theory of perception is correct. The theory in question is what I call a conjunctive theory of veridical experience. According to this view, normal experience of spatio-temporal objects occurs when a subject has a certain perceptual experience, and that experience also happens to match up with and/or be satisfied by what is really the case. Only when a theory of this sort is assumed, I argue, is the claim that we fail to know that the skeptical scenarios fail to obtain found to be obvious. In chapter 5 I argue that, in fact, a non-cognitive theory, rather than a conjunctive theory, is the correct view to maintain. In the final chapter 6 I develop the epistemological position that falls out of accepting a non-cognitive theory. (shrink)

There are few who would deny that P. F. Strawson’s “Freedom and Resentment” (1962) ranks among the most significant contributions to modern moral philosophy. Although any number of essays have been devoted to it, Pamela Hieronymi’s 'Freedom, Resentment, and the Metaphysics of Morals' is the first book-length study. The aim of Hieronymi’s study is to show that Strawson’s “central argument” has been “underestimated and misunderstood.” Hieronymi interprets this argument in terms of what she describes as Strawson’s “social naturalism”. Understood this (...) way, Hieronymi maintains, “the argument is powerful”. In what follows I argue that while Hieronymi’s discussion is stimulating and provides valuable insights into “Freedom and Resentment,” neither the interpretation advanced nor the social naturalist position that it describes is convincing.

In her 2006 paper, A Darwinian Dilemma for Realist Theories of Value, Sharon Street argues that evolutionary psychology, if roughly true, undermines evaluative realism as a metaethical theory. Evolutionary psychology suggests that our moral beliefs track evolutionary pressures, and not realist evaluative truths. Therefore, Street concludes, evaluative realism entails moral skepticism. The most compelling arguments against Street's evolutionary debunking of evaluative realism suggest that its implications are unacceptable. Vavova (2014, 2021) argues that, in order to work, evolutionary debunking entails (...) global skepticism. Parfit (2017), on the other hand, argues that constructivism — Street's alternative to realism —entails nihilism. Both Vavova and Parfit argue that that in order to avoid these unacceptable implications — one epistemic, and the other ethical — evolutionary debunking must either contradict itself or fail to undermine realism. This paper will argue that evolutionary debunking can successfully respond to both of these challenges. (shrink)

Since the resurgence of infinitism in contemporary epistemology, Peter Klein has been consistent in providing arguments against the three other possible solutions (i.e., foundationalism, coherentism, skepticism) to the Regress Problem, which in turn is a key aspect of the justification condition for the traditional account of knowledge as justified true belief. Klein’s successful effort in reviving the often-dismissed solution and further advancing it as the sole solution to the Regress Problem cannot be ignored as he finds it necessary to (...) not only raise problems for the viability of the three contenders but, more so, definitively invalidate them as equally possible solutions. This paper responds to Klein’s objection to foundationalism, the crucial reasons for which he offers in several of his works concerning infinitism and the Regress Problem: i) that foundationalism inevitably leads either to arbitrariness or to the continuation of the regress of reasons; ii) that a proposition continuously enhanced by reasons has more epistemic warrant than a proposition supported by a chain of reasons which ends at basic beliefs, and; iii) that basic beliefs are not tantamount to fully justified beliefs. For each, certain problems can be raised by employing foundationalist arguments in order to arrive at the conclusion that in spite of his astute reasoning, Klein’s objection is insufficient to rule out foundationalism as a possible solution to the Regress Problem.

In lieu of an abstract, here is a brief excerpt of the content:Epistemic Leaks and Epistemic Meltdowns: A Response to William Morris on Scepticism with Regard to Reason Mikael M. Karlsson I. In an excellent paper which appeared in the April, 1989 issue of this journal,2 William Morris attemptsto demonstrate thatthe arguments which make up Hume's notorious chapter, "Of scepticism with regard to reason, are, in the first place, coherent—both internally and with the overall strategy of the Treatise—and, in (...) the second place, successful. Morris' paper is an exercise in the noble art of what I style constructive exegesis, an enterprise to which many readers of Hume Studies, and myself as much as any, are committed. It is a guiding principle ofthis art that we donotunderstandaphilosophical textuntil we can interpret it in such a way as to render it both coherent and correct. From this point ofview, coherence and correctness are not as independent of one another as they may seem to be to others who are differently committed. Some texts, such as Hume's chapter, "Ofscepticism with regard to reason," are notoriously resistant to constructive exegesis, despite the formidable bag of tricks which scholars and interpreters have developed; so resistant, that in gloomier moments we may be brought to wonder about our interpretative enterprise itself. Constructive exegesis is indeed a strange, and peculiarly optimistic, enterprise. Someday, I imagine, in a leisurely moment, I will think more reflectively about the principles ofour art. But not now.6 As a fellow practitioner of constructive exegesis, I am in full sympathy with what Morris tries to do in his paper; and I think that he does contribute substantially to our understanding of what Hume is up to in the chapter, "Ofscepticism with regard to reason." The third section of Morris' paper is, in my judgement, particularly successful in showing how Hume's chapter fits into the larger framework of the Treatise: Hume is, we see, attacking both what Morris labels "intellectualist rationalism" and its counterpart, which we may call 'unmitigated scepticism', although the chapter's two main arguments go primarily to the former. I also think that Morris gives very helpful, Volume XVI Number 2 121 MIKAEL M. KARLSSON and to my mind accurate, accounts of these two arguments, which I dub, respectively, the epistemic leak argument, and the epistemic meltdown argument. However, I have personally never found either of these arguments remotely convincing; and I still do not, despite Morris' clarification and defense. In what follows, I shall indicate some ofthe reasons for my dissatisfaction.?. Theepistemicleakargumentpurportsto"prove"(in Hume's sense)that reason or demonstration cannot support knowledge. Morris rightlyreminds us that whatHume meansby knowledge is perfect assurance or conviction: Knowledge is, in short, subjective certainty. This has caused confusion, for this is not what we usually mean nowadays by knowledge; nor was it what people, philosophers included, generally meant prior to Descartes. In Hume itis the product ofthe attempttoresolve all epistemic statesintomental eventsorwhat he calls "perceptions." In any case, we must—as Morris rightly explains—be clear that the epistemic leak argument is aimed at showing that demonstration cannot supportperfect conviction. Inoutline, the argumentissimple: Itworks, asMorrismakes clear, by shifting attention away from the subject-matter or "objects" of demonstration, that is, relations of ideas, to the exercise of demonstrative reason by human agents. The necessity of relations of ideas may suggest to us that we can be certain about them. Against this, one may point out that people do err in the conclusions arrived at by demonstration; this presumably shows that our (rational) understandingis fallible. And once we recognize this, our confidence in any conclusion produced by exercising this facultyislessened—thus do we move from knowledge, or subjective certainty, toprobability: belief, or imperfect conviction. Arguments ofthis general type (we can call them, using Descartes' famous figure, Totten-apple arguments ) were around long before Hume, although they were more commonly directed against the senses than against reason. We find them in antiquity—in Plato and Sextus Empiricus, for instance —and in Descartes, in parallel passages in the Discourse on Method, the First Meditation and the Principles of Philosophy, wherein one can discern a version directed precisely against reason and demonstration.12 To find out what, if anything, Hume has...

Skepticism is one of the most enduring and profound of philosophical problems. With its roots in Plato and the Sceptics to Descartes, Hume, Kant and Wittgenstein, skepticism presents a challenge that every philosopher must reckon with. In this outstanding collection philosophers engage with skepticism in five clear sections: the philosophical history of skepticism in Greek, Cartesian and Kantian thought; the nature and limits of certainty; the possibility of knowledge and related problems such as perception and the (...) debates between objective knowledge and constructivism; the transcendental method as a response to skepticism and the challenge of naturalism; overcoming the skeptical challenge.

G. E. Moore famously argued against skepticism and idealism by appealing to their inconsistency with alleged certainties, like the existence of his own hands. Recently, some philosophers have offered analogous arguments against revisionary views about ethics such as metaethical error theory. These arguments appeal to the inconsistency of error theory with seemingly obvious moral claims like “it is wrong to torture an innocent child just for fun.” It might seem that such ‘Moorean’ arguments in ethics will stand or (...) fall with Moore’s own arguments in metaphysics and epistemology, in virtue of their shared structure. I argue that this is not so. I suggest that the epistemic force of the canonical Moorean arguments can best be understood to rest on asymmetries in indirect evidence. I then argue that this explanation suggests that Moorean arguments are less promising in ethics than they are against Moore’s own targets. I conclude by examining the competing attempt to vindicate Moorean arguments by appealing to Rawls’s method of reflective equilibrium. (shrink)

Free will skepticism is radical in its core claim that free will is illusory. Criminal law, however, appears to presuppose that persons are free and hence, morally responsible for their actions. So, if free will skepticism is true, our current practices that hold people to account for their wrongs appears unjustified–even immoral. This paper will challenge the free will skeptic’s core claim that free will does not exist and defend current practices of moral responsibility by offering (and defending) (...) a Frankfurtian-compatibilist approach to the topics of free will and determinism.

In his ?Nihilism, Skepticism, and Philosophical Method,? Paul Thagard claims that my critique of his The Brain and the Meaning of Life misapprehends his argument. According to Thagard, the critique wrongly assumes that the book offers foundationalist justifications for Thagard's views whereas, in fact, the justifications his book presents are coherentist. In my response, I show that the claim that my critique depends on foundationalist assumptions is ungrounded. Moreover, the appeal to coherentist rather than foundationalist justifications does not (...) salvage Thagard's discussion, since it is problematic under both foundationalism and coherentism. Thagard does not show that the anti-nihilist position he supports is more coherent than the nihilist position he rejects, and brain research does not justify his claims about the meaning of life under coherentism any more than under foundationalism.

Epistemic contextualists like David Lewis allow that we have substantially infallibilist reflective intuitions about knowledge even though our everyday talk accepts fallibilist attributions of knowledge. They give serious weight to both our everyday talk and our propensity to assent to the skeptic's conclusions, and give us a concept of knowledge that accommodates both. The skeptic would, of course, leverage such infallibilist intuitions in order to undermine the legitimacy of our everyday attributions. Most contemporary epistemologists would simply argue that our concept (...) of knowledge is fallibilist, but this doesn't give them a particularly convincing reply to intuitively compelling skeptical arguments. ;This essay, most generally, takes up the question of how best to argue about skepticism. I claim that a philosophical account of knowledge that responds to skepticism should be able to clearly accommodate our epistemic agency. In chapter 1 I explain how skepticism challenges our naIve conception of agency and introduce two criteria for an adequate response to skepticism. In chapter 2, I discuss contextualist solutions; I argue they fail to satisfy our criteria and fail on their own terms; I explain how both failures relate to a failure to adequately treat epistemic agency. In chapter 3 I develop a conception of epistemic agency that describes what it is to be an active, reasoning source of belief. This picture is at odds with a dominant strain of epistemology that has it that one is substantially subject to belief, not effectively responsible for it; I criticize an influential argument by Bernard Williams that claims belief is not an attitude we control. This discussion in chapter 3 gives support to, a rationale for, the anti-insulationism requirement set out in chapter 1. Finally, in chapter 4 I return to the methodological issues of how to argue about skepticism. I first defend the idea that a knowledge-based skepticism is worth philosophical attention. I then offer an interpretation of what the skeptic is up to, and discuss what an effective counterstrategy might look like; I suggest that a particular sort of normative argument is the best way with the skeptic.

Skeptical theism combines theism with skepticism about the ability of human beings to know God's reasons for permitting suffering. In recent years, it has become perhaps the most prominent theistic response from philosophers to the evidential argument from evil. Some critics of skeptical theism charge that it implies positions that theists and many atheists alike would reject, such as skepticism about our knowledge of the external world and about our knowledge of our moral obligations. I discuss these (...) charges, with emphasis on the charge of moral skepticism. I argue that the charges have merit, and I conclude by rebutting the claim that God's commands could give skeptical theists moral guidance despite the morally skeptical implications of their position.

In the article of Bueno titled “Davidson and Skepticism: How Not to Respond to the Skeptic,” he intends to demonstrate that although Davidson’s theory of Coherence holds many attractions, it does not entail a response to any kinds of skepticism including Global, Lottery, and Pyrrhonian. In this study, the goal is to criticize the work of Prof. Bueno in connection with two criticisms raised by him over Davidson’s anti-skeptical strategy. Further, by giving some reasons in favor of (...) Davidson’s anti-skepticism argument, it will be shown that neither the above stated criticisms nor the global skepticism response could undermine the validity of anti-skepticism argument. (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.

A new kind of skepticism about philosophy is articulated and argued for. The key premise is the claim that many of us are well aware that in the past we failed to have good responses to substantive objections to our philosophical beliefs. The conclusion is disjunctive: either we are irrational in sticking with our philosophical beliefs, or we commit some other epistemic sin in having those beliefs.

In this paper, I defend Moorean Dogmatism against a novel objection raised by Adam Leite. Leite locates the defectiveness of the Moorean reasoning explicitly not in the failure of the Moorean argument to transmit warrant from its premises to its conclusion but rather in the failure of an epistemic agent to satisfy certain epistemic responsibilities that arise in the course of conscious and deliberate reasoning. I will first show that there exist cases of Moorean reasoning that (...) are not put into jeopardy by the considerations that Leite presents. Second, I will argue that certain commitments of Leite’s concerning the notion of warrant are in tension with his verdict that the Moorean reasoning is defective. (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)

This paper applies speech-act theory to craft a new response to Pyrrhonian skepticism and diagnose its appeal. Carefully distinguishing between different levels of language-use and noting their interrelations can help us identify a subtle mistake in a key Pyrrhonian argument.

This essay deals with a selected part of an epistemological controversy provided by Tūsī in response to the skeptical arguments reported by Rāzī that is related to what might be called "intellectual skepticism," or skepticism regarding the judgments of the intellect, particularly in connection with self-evident principles. It will be shown that Rāzī has cited and exposed a position that seems to be no less than a medieval version of empiricism. Tūsī, in contrast, has presented us with (...) a position that rejects such empiricism. The comparative aim of this essay is to draw attention to some similarities as well as some points of divergence between the kind of skeptical debate we are focusing on here, and some relevant epistemological discussions in the later traditions in the West.

The Cartesian arguments for external world skepticism are usually considered to be significant for at least two reasons: they seem to present genuine paradoxes and that providing an adequate response to these arguments would reveal something epistemically important about knowledge, justification, and/or our epistemic position to the world. Using only premises and reasoning the skeptic accepts, I will show that the most common Cartesian argument for external world skepticism leads to a previously unrecognized self-undermining dilemma: it either (...) leads to a reductio ad absurdum, or to avoid this reductio the skeptic must accept that this argument is epistemically idle—it does not provide any support for external world skepticism. Either way, this Cartesian argument cannot legitimately threaten or even call into question our beliefs about the external world. And thus, either way, this Cartesian argument for external world skepticism is not epistemically significant—it is not a genuine paradox and adequately responding to it need not reveal anything epistemically important.

According to some powerful skeptical arguments, we know almost nothing. Contextualist theories of knowledge ascriptions have been developed with an eye toward resisting skepticism. Have the contextualists succeeded? After briefly outlining their view, I will consider whether contextualism about knowledge ascriptions provides a satisfactory response to one of the most popular and influential forms of skepticism. I conclude with some questions for the contextualist. As we’ll see, the effectiveness of the contextualist solution to skepticism is far (...) from settled. (shrink)

Metaethical Mooreanism is the view that without being able to explain how we know certain moral claims we can nevertheless be sure that we do know them. In this paper I focus on the Moorean argument against moral error theory. I conclude that it fails. To show this failure, I first distinguish Moorean claims from Moorean arguments, and then so-called presumptive support from dialogical support. With these distinctions in place, I argue that the key Moorean claim (...) requires dialogical support in order to be used within the Moorean argument against moral error theory, but metaethical Mooreans have only provided presumptive support for the Moorean claim. Not only is this presumptive support inadequate for fending off the moral error theory, it is doubtful that Mooreans can actually provide dialogical support for the key Moorean claim. (shrink)

I develop a new version of the ordinary language response to skepticism. My version is based on premises about the practical functions served by our epistemic words. I end by exploring how my argument against skepticism is interestingly non-circular and philosophically valuable.

Many philosophers have found in Hume’s skeptical doubts concerning the operations of the understanding the materials for an argument that generalizes from induction to other domains, like our beliefs in the external world, other minds, and the past. This chapter offers a novel reconstruction of that argument and identifies the principles that are responsible for its capacity to generalize beyond induction. Next, it presents a classical reading of Hume’s skeptical solution and shows that Crispin Wright’s entitlement theory is close in (...) spirit to it. After that, it develops two objections to entitlement theory: it relies on the truth of deeply contingent propositions that are not a priori rational, and it does not manage to redefine the concept of epistemic rationality while offering an effective anti-skeptical response. The chapter concludes with a constructive suggestion: some passages that support a non-classical reading of Hume’s positive views on induction offer the materials to reject the steps of the skeptical argument that cause trouble for entitlement theory.

There is conflicting experimental evidence about whether the “stakes” or importance of being wrong affect judgments about whether a subject knows a proposition. To date, judgments about stakes effects on knowledge have been investigated using binary paradigms: responses to “low” stakes cases are compared with responses to “high stakes” cases. However, stakes or importance are not binary properties—they are scalar: whether a situation is “high” or “low” stakes is a matter of degree. So far, no experimental work has investigated the (...) scalar nature of stakes effects on knowledge: do stakes effects increase as the stakes get higher? Do stakes effects only appear once a certain threshold of stakes has been crossed? Does the effect plateau at a certain point? To address these questions, we conducted experiments that probe for the scalarity of stakes effects using several experimental approaches. We found evidence of scalar stakes effects using an “evidence seeking” experimental design, but no evidence of scalar effects using a traditional “evidence-fixed” experimental design. In addition, using the evidence-seeking design, we uncovered a large, but previously unnoticed framing effect on whether participants are skeptical about whether someone can know something, no matter how much evidence they have. The rate of skeptical responses and the rate at which participants were willing to attribute “lazy knowledge”—that someone can know something without having to check—were themselves subject to a stakes effect: participants were more skeptical when the stakes were higher, and more prone to attribute lazy knowledge when the stakes were lower. We argue that the novel skeptical stakes effect provides resources to respond to criticisms of the evidence-seeking approach that argue that it does not target knowledge. (shrink)

A long critical notice of Michael Forster's recent book, "Kant and Skepticism." We argue that Forster's characterization of Kant's response to skepticism is both textually dubious and philosophically flawed. -/- .
