This paper argues that we should reject G. E. Moore’s anti-skeptical argument as it is presented in “Proof of an External World.” However, the reason I offer is different from traditional objections. A proper understanding of Moore’s “proof” requires paying attention to an important distinction between two forms of skepticism. I call these Ontological Skepticism and Epistemic Skepticism. The former is skepticism about the ontological status of fundamental reality, while the latter is skepticism about our empirical knowledge. (...) Philosophers often assume that Moore’s response to “external world skepticism” deals exclusively with the former, not the latter. But this is a mistake. I shall argue that Moore’s anti-skeptical argument targets an ontological form of skepticism. Thus, the conclusion is an ontological claim about fundamental reality, while the premises are epistemic claims. If this is correct, then the conclusion outstrips the scope of its premises and proves too much. (shrink)

A certain skeptical strategy involves a skeptical hypothesis that closely mirrors the structure of our standard theory of the world; this strategy insulates the skeptical argument from attacks based on standard criteria of theory choice. A standard reply to this strategy is to claim that proffered alternative is just the standard theory expressed in a different notation. But this reply does not succeed, given plausible assumptions about semantics. However, there is an alternative strategy--also semantical--which can deal (...) with the problem, at least in those cases where, intuitively, the skeptic's challenge should fail. (shrink)

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.

Nietzsche, in his work On the Genealogy of Morals, argues that human cognition is analogous in certain significant respects to the perspectival nature of optical vision. Because of this analogy, his account of human cognition is often referred to as perspectivism. Brian Leiter argues that Nietzsche’s use of this optical perspective metaphor undermines interpretations that take perspectivism to have radically skeptical implications. In this paper, I examine Leiter’s argument and show that the considerations he raises based on the (...) optical perspective metaphor are insufficient to undermine the claim that perspectivism entails radical skepticism.

In this chapter, I consider personal and impersonal anti-theism and personal and impersonal pro-theism. I show that skeptical theism undermines arguments for personal anti-theism and impersonal anti-theism. Next, I show that (at least some) arguments for personal and impersonal pro-theism are not undermined by skeptical theism. This throws a wrench in debates about the axiology of theism: if skeptical theism is true, then it is very difficult to establish certain positions in answer to the (...) axiological question about God.

I’m going to argue for a set of restricted skeptical results: roughly put, we don’t know that fire engines are red, we don’t know that we sometimes have pains in our lower backs, we don’t know that John Rawls was kind, and we don’t even know that we believe any of those truths. However, people unfamiliar with philosophy and cognitive science do know all those things. The skeptical argument is traditional in form: here’s a skeptical hypothesis; (...) you can’t epistemically neutralize it, you have to be able to neutralize it to know P; so you don’t know P. But the skeptical hypotheses I plug into it are “real, live” scientific-philosophical hypotheses often thought to be actually true, unlike any of the outrageous traditional skeptical hypotheses (e.g., ‘You’re a brain in a vat’). So I call the resulting skepticism Live Skepticism. Notably, the Live Skeptic’s argument goes through even if we adopt the clever anti-skeptical fixes thought up in recent years such as reliabilism, relevant alternatives theory, contextualism, and the rejection of epistemic closure. Furthermore, the scope of Live Skepticism is bizarre: although we don’t know the simple facts noted above, many of us do know that there are black holes and other amazing facts. (shrink)

The first article of the cycle “The role of skeptical evidence in the First and Second ‘Meditations’” compares the Cartesian and Sextus Empiricus’ concepts of doubt in, respectively, “Metaphysical meditations” and “Outlines of Pyrrhonism”. The article starts with the current state of the problem “Descartes and skepticism” and admits the existence of consensus about Cartesian perception of skeptical tradition: Cartesius (1) was influenced by all skeptical movements, known in his time, and (2) created a generalized notion that (...) contains elements of both Academic and Pyrrhonian origin. This consensus is the source of many contemporary studies on how different skeptical doctrines influenced certain parts of Cartesian philosophy. This article attempts to analyze possible Descartes’ use of Sextus Empiricus’ notion of phenomenon. Sextus clearly states in “Outlines of Pyrrhonism” that one cannot doubt phenomenon as something perceived directly. The article proves that (a) Sextus’ thesis about the “sensory” nature of phenomenon is metaphorical, so far as it includes (without distinction) both sensuality and the experience of thinking; (b) the phenomenon is realized through a wide range of passive states of mind that all have irresistible force of influence; (c) the impact of phenomena is always mediated by our self, because all skeptical phrases are strictly correlated with the first person singular. Some researchers distinguish Sextus’ isostenia, as one of such insurmountable states, from Cartesian doubt at the First Meditation, which is allegedly based on a purely volitional decision. The article proved that this argument is artificial, since Descartes’ volitional decision is caused by initial inability to take the dubious as if it were certain. Thus, Cartesian approach can be considered a specific kind of isostenia. Such parallelism is a reason to assume a key role of Sextus’ understanding of insurmountable power of phenomena in Cartesian anti-sceptical argumentation. This assumption will be tested in the following articles of the cycle. (shrink)

Arguments from disagreement against moral realism begin by calling attention to widespread, fundamental moral disagreement among a certain group of people. Then, some skeptical or anti-realist-friendly conclusion is drawn. Chapter 2 proposes that arguments from disagreement share a structure that makes them vulnerable to a single, powerful objection: they self-undermine. For each formulation of the argument from disagreement, at least one of its premises casts doubt either on itself or on one of the other premises. On reflection, (...) this shouldn’t be surprising. These arguments are intended to support very strong metaphysical or epistemological conclusions about morality. They must therefore employ very strong metaphysical or epistemological premises. But, given the pervasiveness of disagreement in philosophy, especially about metaphysics and epistemology, very strong premises are virtually certain to be the subject of widespread, intractable disagreement—precisely the sort of disagreement that proponents of these arguments think undermine moral claims. Thus, these arguments undermine their own premises. If Chapter 2’s argument is sound, it provides realists with a single, unified strategy for responding to any existing or forthcoming arguments from disagreement. (shrink)

Forms of justification. On the structure and scope of self-refutation arguments in Plato, Cicero and Apel. - In this essay, the structure and scope of transcendental types of argumentation are analyzed, compared and criticized on the basis of the reception of two antiskeptical types of reasoning in ancient philosophy (Plato, Parmenides 135b-c; Cicero, Lucullus § 28) by a contemporary philosophical author (Karl-Otto Apel). Plato puts forward a transcendental argument for the inevitability of a final knowledge. Cicero argues that a (...) principle of fallibilism occurring with universal claim contradicts itself. In Karl-Otto Apel's transcendental pragmatic variant of philosophy, the two types of self-refutation arguments developed in Plato's and Cicero's dialogues are brought together into a single argumentation.

Autologos. A dialogue on fundamental logic. - In this dialogue of three dialogue partners, an attempt is made to prove the logical prerequisites of any meaningful dialogue by using transcendental arguments.

A symposium on my *Objects: Nothing Out of the Ordinary* (2015). In response to Wallace, I attempt to clarify the dialectical and epistemic role that my arguments from counterexamples were meant to play, I provide a limited defense of the comparison to the Gettier examples, and I embrace the comparison to Moorean anti-skeptical arguments. In response to deRosset, I provide a clearer formulation of conservatism, explain how a conservative should think about the interaction between intuition and science, and (...) discuss what conservatives should say about scattered territories, clonal colonies, and arbitrary systems. In response to Tillman and Spencer, I fortify my original presentation of the debunking arguments by clarifying why, even while trees (if they exist) are paradigmatically causal, conservatives are meant to be rationally obstructed from believing that it is trees that are causing our tree beliefs.

Wouter Kusters argues that madness has much to offer philosophy, as does philosophy to madness. In this paper, i support both claims by drawing on a mad phenomenon which I label Radical Psychotic Doubt, or RPD. First, although skepticism is a minority position in epistemology, it has been claimed that anti-skeptical arguments remain unsatisfying. I argue that this complaint can be clarified and strengthened by showing that anti-skeptical arguments are irrelevant to RPD sufferers. Second, there's a (...) debate about whether so-called hinge commitments are beliefs or not. I argue that RPD can be used to strengthen the case that they are. Moreover, if hinges are beliefs, some madpeople are more epistemically rational than some sane philosophers. Third, drawing on my own mad experiences, I challenge evidentialism by presenting a better candidate for a truly forced cchoice about what to believe than William James' traditional religious example. I further show that in certain psychiatric contexts, evidentialism has more radical implications than Jamesian pragmatism, which comes out as more conservative. Finally, I discuss how philosophical theories like pragmatism and Pyrrhonism can provide inspiration for new and much-needed coping strategies for RPD sufferers. (shrink)

This chapter analyzes two short texts in which Peirce sketches out an anti-skeptical argument inspired by Kant’s refutation of idealism. The chapter will first consider why Peirce found Kant’s argument interesting and promising, given that it is often regarded as problematic and unsuccessful. It will then briefly reconstruct Kant’s refutation, highlighting its most problematic passages. Moreover, since Peirce’s own version of the argument relies on Kant’s views regarding the temporal structure of consciousness, the chapter will (...) explain how Peirce tackles this issue in “The Law of Mind.” Finally, the chapter considers Peirce’s own anti-skeptical argument and examines whether and how it can be seen as appropriating Kant’s strategy.

Global meta-philosophical skepticism (i.e. completely unrestricted skepticism about philosophy) based upon disagreement faces the problem of self-defeat since it undercuts its motivating conciliatory principle. However, the skeptic may easily escape this threat by adopting a more modest kind of skepticism, that will be called “extensive meta-philosophical skepticism”, i.e., the view that most of our philosophical beliefs are unjustified, except our beliefs in epistemically fundamental principles. As I will argue in this paper, this kind of skepticism is well-motivated, does not undercut (...) the conciliatory principle, but still poses a radical challenge to philosophy as a cognitive discipline. Moreover, I will argue that non-global skepticism that is still extensive undermines itself as well. The deeper reason for this is that this more modest kind of skepticism can only be motivated by the assumption that disagreement with philosophical peers is abundant and that we can identify peers only by relying on track-record arguments. But then one can argue for extensive meta-philosophical skepticism only if one presupposes that those philosophical beliefs that form the basis of track-record evaluations are justified. Here, the threat of self-defeat looms again. I will proceed by first defending the premises of this new anti-skeptical argument against standard objections from the literature. Second, I will show in more detail where the epistemic inconsistency arises in the argument for extensive meta-philosophical skepticism. I conclude with an assessment of the scope and the limits of my argument. (shrink)

In this paper I argue first, that a contrastive account of self-knowledge and the propositional attitudes entails an anti-individualist account of propositional attitude concepts, second, that the final account provides a solution to the McKinsey paradox, and third, that the account has the resources to explain why certain anti-skeptical arguments fail.

Hilary Putnam has famously argued that “we are brains in a vat” is necessarily false. The argument assumes content externalism (also known as semantic externalism and anti-individualism), that is, the view that the individuation conditions of mental content depend, in part, on external or relational properties of the subject’s environment. Recently content externalism has given rise to the hypothesis of the extended mind, whereby mental states are not only externally individuated but also externally located states. This chapter argues (...) that when content externalism is combined with the extended mind hypothesis it is robbed of its anti-skeptical power. Given the extended mind hypothesis, the supercomputer and the envatted brain can be regarded as aspects of the extended mind of the evil scientist. On this view, the thought contents of the coupled brain–computer–scientist system do not differ from those of a normal human. But without a difference in thought contents Putnam’s anti-skeptical argument crumbles. (shrink)

Erik Wielenberg recently invoked the parent-child analogy in an argument against Christian theism. The argument relies on the claim that a loving parent would never allow her child to feel abandoned in the midst of what feels like gratuitous suffering. In this paper, I offer three clear counterexamples to Wielenberg’s central premise. At the same time, a successful counterexample does not a robust theology of suffering make. To that end, and with a careful eye towards anti-theodical concerns, (...) I defend the need for a more proactive Christian philosophical examination of the role of suffering in a meaningful life.

In the text the author tries to investigate Wittgenstein’s notions of action, practice and pragmatism in his book On Certainty. An attempt is made to sketch the criterion of Wittgenstein’s analysis of certainty and to define the crucial concepts such as world-picture, practice, certainty and justification. The analysis shows that Wittgenstein applies a specific form of pragmatic solution to the problem of justification, which after all, can and should be called a kind of pragmatismus. This is the subject of the (...) first and the second part of the text. The third part shows the application of this pragmatic theory of justification to Wittgenstein’s refutation of scepticism. The author suggests that his pragmatic analysis of certainty presents an adequate means for the refutation of scepticism. However, his anti-scepticism is situated in the tradition of common sense and ordinary language philosophy and epistemology (Moore, Chisholm, Lehrer, Austin, Grice, Strawson, etc.). In the conclusion the author applies this anti-sceptical solution to the so called rule-following problem (as stated in Kripke’s work) and shows that there are some far reaching consequences of this interpretation of Wittgenstein’s later work to his position on language, learning, ontology and knowledge.

Semantic contextualism is often used in order to offer solutions for problems in other branches of philosophy, including epistemology. One of such attempts is epistemic contextualism, according to which the semantic value of the word “knows” changes with the context of its utterance. The aim of this paper is to critically investigate Keith DeRose’s contextualism to see up to what extent does it provide a valid anti-sceptical strategy. I argue that while it can be seen as a good rival (...) for global and Ungerian scepticism, it does not lead to the refutation of other variants of classical scepticism. (shrink)

This critical study of Anthony Brueckner’s essay collection on skepticism emphasizes interconnections between the various essays. In particular, it considers Brueckner’s discussion of transcendental anti-skeptical arguments from the theses of anti-individualism and privileged self-knowledge. Finally, some overarching methodological lessons are drawn.

This paper provides a reinterpretation of some of the most influential skeptical arguments, Agrippa’s trilemma, meta-regress arguments, and Cartesian external world skepticism. These skeptical arguments are reasonably regarded as unsound arguments about the extent of our knowledge. However, reinterpretations of these arguments tell us something significant about the preconditions and limits of persuasive argumentation. These results contribute to the ongoing debates about the nature and resolvability of deep disagreement. The variety of skeptical arguments shows that we must (...) distinguish different types of deep disagreement. Moreover, the reinterpretation of skeptical arguments elucidates that deep disagreement cannot be resolved via argumentation. (shrink)

JOURNAL OF THE HISTORY OF PHILOSOPHY PRIZE for the best published book in the history of philosophy [Awarded in 2010] _______________ -/- Although it is widely recognized that David Hume's A Treatise of Human Nature (1739-40) belongs among the greatest works of philosophy, there is little agreement about the correct way to interpret his fundamental intentions. It is an established orthodoxy among almost all commentators that skepticism and naturalism are the two dominant themes in this work. The difficulty has been, (...) however, that Hume's skeptical arguments and commitments appear to undermine and discredit his naturalistic ambition to contribute to "the science of man". This schism appears to leave his entire project broken-backed. The solution to this riddle depends on challenging another, closely related, point of orthodoxy: namely, that before Hume published the Treatise he removed almost all material concerned with problems of religion. Russell argues, contrary to this view, that irreligious aims and objectives are fundamental to the Treatise and account for its underlying unity and coherence. It is Hume's basic anti-Christian aims and objectives that serve to shape and direct both his skeptical and naturalistic commitments. When Hume's arguments are viewed from this perspective we can solve, not only puzzles arising from his discussion of various specific issues, we can also explain the intimate and intricate connections that hold his entire project together. This "irreligious" interpretation provides a comprehensive fresh account of the nature of Hume's fundamental aims and ambitions in the Treatise. It also presents a radically different picture of the way in which Hume's project was rooted in the debates and controversies of his own time, placing the Treatise in an irreligious or anti-Chrisitan philosophical tradition that includes Hobbes, Spinoza and freethinking followers. Considered in these terms, Hume's Treatise constitutes the crowning achievement of the Radical Enlightenment. (shrink)

Every account of moral responsibility has conditions that distinguish between the consequences, actions, or traits that warrant praise or blame and those that do not. One intuitive condition is that praiseworthiness and blameworthiness cannot be affected by luck, that is, by factors beyond the agent’s control. Several philosophers build their accounts of moral responsibility on this luck-free condition, and we may call their views Luck-Free Moral Responsibility (LFMR). I offer moral and metaphysical arguments against LFMR. First, I maintain that considerations (...) of fairness that often motivate LFMR do not require its adoption. Second, I contend that LFMR has counterintuitive implications for the nature and scope of praiseworthiness and blameworthiness and that LFMR is vulnerable to a reductio ad absurdum. Third, I state some common reasons for thinking that LFMR’s commitment to true counterfactuals of libertarian freedom is problematic, and I argue that if there are no such true counterfactuals and if LFMR is true, a person is praiseworthy and blameworthy at most for a tiny fraction of her actions. Fourth, I argue that proponents of LFMR cannot escape this skeptical cost by appealing to a different kind of counterfactual of freedom. Fifth, I develop an anti-skeptical motivation to affirm the idea that luck can affect moral responsibility. (shrink)

Peter Graham has recently given a dilemma purportedly showing the compatibility of libertarianism about free will and the anti-skeptical epistemology of testimony. In the first part of this paper I criticize his dilemma: the first horn either involves a false premise or makes the dilemma invalid. The second horn relies without argument on an implausible assumption about testimonial knowledge, and even if granted, nothing on this horn shows libertarianism does not entail skepticism about testimonial justification. I then (...) argue for the incompatibility of (i) a view entailed by Open Theism, viz., that there are no true counterfactuals of freedom, (ii) a popular form of process reliabilism about justification and knowledge, and (iii) a weak anti-skepticism about testimonial justification and knowledge. I conclude that there is a costly tension between certain views about testimony and about free will. (shrink)

Epistemologists understand radical skepticism as arising from two principles: Closure and Underdetermination. Both possess intuitive prima facie support for their endorsement. Understanding how they engender skepticism is crucial for any reasonable anti-skeptical attempt. The contemporary discussion has focused on elucidating the relationship between them to ascertain whether they establish distinct skeptical questions and which of the two constitutes the ultimately fundamental threat. Major contributions to this debate are due to Brueckner, Cohen, and Pritchard. This contribution aims at (...) defending Brueckner’s contention that underdetermination expresses the fundamental skeptical threat and that the closure-based argument can ultimately be reduced to it, at least concerning skeptical contexts. This will be achieved by undermining Cohen’s objections to Brueckner on both counts. Cohen’s argument endorses a picture of evidential underdetermination, which, while apt for non-skeptical contexts, cannot be applied to radical skepticism. A comparison with a case of scientific underdetermination is developed to argue for this idea. Our argument is then applied to the principle equivalence issue and to objections against it. It is then shown how this analysis possesses a distinctive effect on our understanding of the skeptical threat and the assessment of successful anti-skeptical strategies. (shrink)

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.

I will compare Lehrer’s anti-skeptical strategy from a coherentist point of view with the anti-skeptical strategy of the Mooreans. I will argue that there are strong similarities between them: neither can present a persuasive argument to the skeptic and both face the problem of easy knowledge in one way or another. However, both can offer a complete and self-explanatory explanation of knowledge although Mooreanism can offer the more natural one. Hence, one has good reasons to (...) prefer Mooreanism to Lehrer’s anti-skeptical approach, if one does not prefer coherentism to foundationalism for other reasons. (shrink)

Climate change has become one of the most pressing problems that can threaten the existence and development of humans around the globe. Almost all climate scientists have agreed that climate change is happening and is caused mainly by greenhouse gas emissions induced by anthropogenic activities. However, some groups still deny this fact or do not believe that climate change results from human activities. This essay discusses the causes, significance, and skeptical arguments of climate change denialism, as well as the (...) roles of scientists and science communication in addressing the issues. Through this essay, we call for the active participation of scientists in science communication activities with the public, the opening of new science communication sectors specified for climate change, and more attention to social sciences and humanities in addressing climate change issues.

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.

We revisit an important exchange on the problem of radical skepticism between Richard Rorty and Michael Williams. In his contribution to this exchange, Rorty defended the kind of transcendental approach to radical skepticism that is offered by Donald Davidson, in contrast to Williams’s Wittgenstein-inspired view. It is argued that the key to evaluating this debate is to understand the particular conception of the radical skeptical problem that is offered in influential work by Barry Stroud, a conception of the (...) class='Hi'>skeptical problem which generates metaepistemological ramifications for anti-skeptical theories. In particular, we argue that, contra Williams, Rorty’s view that Davidson was offering a theoretical diagnosis of radical skepticism can be consistently maintained with his transcendental approach.

This paper discusses a wide range of anti-naturalistic argument from reason due to Balfour, Haldane, Joad, Lewis, Taylor, Moreland, Plantinga, Reppert, and Hasker.

Further, I argue that some of these arguments do not even pose prima facie plausible challenges to naturalism. In the concluding part of my discussion, I draw attention to some distinctive differences between Hasker’s anti-naturalistic arguments and the (...) other anti-naturalistic arguments mentioned above.

In chapter 7 of The Varieties of Reference, Gareth Evans claimed to have an argument that would present "an antidote" to the Cartesian conception of the self as a purely mental entity. On the basis of considerations drawn from philosophy of language and thought, Evans claimed to be able to show that bodily awareness is a form of self-awareness. The apparent basis for this claim is the datum that sometimes judgements about one’s position based on body sense are immune (...) to errors of misidentification relative to the first-person pronoun 'I'. However, Evans’s argument suffers from a crucial ambiguity. 'I' sometimes refers to the subject's mind, sometimes to the person, and sometimes to the subject's body. Once disambiguated, it turns out that Evans’s argument either begs the question against the Cartesian or fails to be plausible at all. Nonetheless, the argument is important for drawing our attention to the idea that bodily modes of awareness should be taken seriously as possible forms of self-awareness. (shrink)

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.

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.

Sceptical theists--e.g., William Alston and Michael Bergmann--have claimed that considerations concerning human cognitive limitations are alone sufficient to undermine evidential arguments from evil. We argue that, if the considerations deployed by sceptical theists are sufficient to undermine evidential arguments from evil, then those considerations are also sufficient to undermine inferences that play a crucial role in ordinary moral reasoning. If cogent, our argument suffices to discredit sceptical theist responses to evidential arguments from evil.

I present an argument for a sophisticated version of sceptical invariantism that has so far gone unnoticed: Bifurcated Sceptical Invariantism (BSI). I argue that it can, on the one hand, (dis)solve the Gettier problem, address the dogmatism paradox and, on the other hand, show some due respect to the Moorean methodological incentive of ‘saving epistemic appearances’. A fortiori, BSI promises to reap some other important explanatory fruit that I go on to adduce (e.g. account for concessive knowledge attributions). BSI (...) can achieve this much because it distinguishes between two distinct but closely interrelated (sub)concepts of (propositional) knowledge, fallible-but-safe knowledge and infallible-and-sensitive knowledge, and explains how the pragmatics and the semantics of knowledge discourse operate at the interface of these two (sub)concepts of knowledge. I conclude that BSI is a novel theory of knowledge discourse that merits serious investigation. (shrink)

ABSTRACTThis article offers a novel sceptical argument that the sensitivity-contextualist must say is sound; moreover, she must say that the conclusion of this argument is true at ordinary standards. The view under scrutiny has it that in different contexts knowledge-attributing sentences express different propositions, propositions which differ in the stretch of worlds across which the subject is required to track the truth. I identify the underlying reason for the sceptical result and argue that it makes sensitivity-contextualism irremediably flawed. (...) Contextualists, I conclude, should abandon sensitivity for some other piece of epistemic machinery. (shrink)

Today we find philosophical naturalists and Christian theists both expressing an interest in virtue epistemology, while starting out from vastly different assumptions. What can be done to increase fruitful dialogue among these divergent groups of virtue-theoretic thinkers? The primary aim of this paper is to uncover more substantial common ground for dialogue by wielding a double-edged critique of certain assumptions shared by `scientific' and `theistic' externalisms, assumptions that undermine proper attention to epistemic agency and responsibility. I employ a responsibilist virtue (...) epistemology to this end, utilizing it most extensively in critique of Alvin Plantinga’s Warranted Christian Belief (2000). Epistemological externalism presages, I also argue, a new demarcation problem, but a secondary aim of the paper is to suggest reasons to think that `responsibilist externalism,' especially as glossed in virtue-theoretic terms, provides its proponents with the ability to adequately address this problem as we find it represented in a potent thought-experiment developed by Barry Stroud.

Molinists offer a tempting bargain: accept divine middle knowledge, and reap solutions to a number of philosophical/theological problems. The prime benefit we are meant to reap from middle knowledge is a solution to the problem of freedom and providence. I argue that they cannot deliver. Even if we make metaphysical and semantic assumptions that have generally been considered friendly to Molinism, Molinism is in danger of undermining divine providence altogether. This “collapse" persists despite fairly uncontroversial assumptions, and plagues the best (...) Molinist theories defended in the literature. (shrink)

I argue that no successful version of Williamson's anti‐luminosity‐argument has yet been presented, even if Srinivasan's further elaboration and defence is taken into account. There is a version invoking a coarse‐grained safety condition and one invoking a fine‐grained safety condition. A crucial step in the former version implicitly relies on the false premise that sufficient similarity is transitive. I show that some natural attempts to resolve this issue fail. Similar problems arise for the fine‐grained version. Moreover, I argue (...) that Srinivasan's defence of the more contentious fine‐grained safety condition is also unsuccessful, again for similar reasons. (shrink)

This paper will offer a systematic reconstruction of al-Ġazālī’s Sceptical Argument in his celebrated Deliverer/Delivered from Going Astray (al-Munqiḏ/al-Munqaḏ min al-Ḍalāl). Based on textual evidence, I will argue that the concept of certainty (yaqīn) in play in this argument is that of the philosophers—most notably Ibn Sīnā—and that it is firmly tied to demonstration (burhān) and hence to the materials of syllogism (mawwād al-qiyās). This will show that contrary to what many scholars believe, this Sceptical Argument is (...) al-Ġazālī’s discovery of a latent sceptical problem in Muslim philosophers’ epistemological theories based on Aristotle’s Posterior Analytics that escaped even the agile mind of aš-šayḫ ar-raʾīs Ibn Sīnā. This reconstruction will also shed some light on the widespread assumption that al-Ġazālī anticipates Descartes’s sceptical considerations in the First Meditation. I will argue that not only do the two thinkers use incompatible strategies to reach their respective sceptical conclusions, but both their conclusions and their use of God in refuting them are also essentially non-identical. The conclusion is that the two sceptical arguments are essentially different. (shrink)

Although delusions are typically regarded as beliefs of a certain kind, there have been worries about the doxastic conception of delusions since at least Bleuler’s time. ‘Anti-doxasticists,’ as we might call them, do not merely worry about the claim that delusions are beliefs, they reject it. Reimer’s paper weighs into the debate between ‘doxasticists’ and ‘anti-doxasticists’ by suggesting that one of the main arguments given against the doxastic conception of delusions—what we might call the functional role objection—is based (...) on a fallacy.

Anti-intellectualism involves general mistrust of scholars, academics, and ex- perts, often as pretentious or power-motivated. While scholars have described currents of anti-intellectualism in American public life, evangelical Christianity, in responses to COVID, and rural identity, to my knowledge none have looked at how anti-intellectualism specifically manifests in the New Atheism movement. In this work, we explore the way anti-intellectualism is commonly found and expressed in New Atheism and the modern Skeptical Movement, including scientific skepticism more (...) generally. (shrink)

In this paper, I offer reasons for thinking that two prominent sceptical arguments in the literature – the underdetermination-based sceptical argument and the closure-based sceptical argument – are less philosophically interesting than is commonly supposed. The underdetermination-based argument begs the question against a non-sceptic and can be dismissed with little fanfare. The closure-based argument, though perhaps not question-begging per se, does rest upon contentious assumptions that a non-sceptic is under no pressure to accept.

In this chapter, I argue that it is impossible to trust the Big Tech companies, in an ethically important sense of trust. The argument is not that these companies are untrustworthy. Rather, I argue that the power to hold the trustee accountable is a necessary component of this sense of trust, and, because these companies are so powerful, they are immune to our attempts, as individuals or nation-states, to hold them to account. It is, therefore, literally impossible to trust (...) Big Tech. After introducing the accounts of trust and power that I deploy, I argue that Big Tech companies have four kinds of power that render them unaccountable: fiscal power, political power, data power, and cognitive power. I conclude by reflecting on recent calls to break up the Big Tech firms, suggesting a new antitrust test in the light of my arguments. (shrink)

Sceptical theists undermine the argument from evil by claiming that our ability to distinguish between justified and unjustified evil is weak enough that we must take seriously the possibility that all evil is justified. However, I argue that this claim leads to a dilemma: either our judgements regarding unjustified evil are reliable enough that the problem of evil remains a problem, or our judgements regarding unjustified evil are so unreliable that it would be misguided to use them in our (...) decision-making. The first horn undermines theism, while the second undermines our moral decision-making. Thus, sceptical theism is problematic. (shrink)

An important objection to signaling approaches to representation is that, if signaling behavior is driven by the maximization of usefulness, then signals will typically carry much more information about agent-dependent usefulness than about objective features of the world. This sort of considerations are sometimes taken to provide support for an anti-realist stance on representation itself. The author examines the game-theoretic version of this skeptical line of argument developed by Donald Hoffman and his colleagues. It is shown that (...) their argument only works under an extremely impoverished picture of the informational connections that hold between agent and world. In particular, it only works for cue-driven agents, in Kim Sterelny’s sense. In cases in which the agents’ understanding of what is useful results from combining pieces of information that reach them in different ways, and that complement one another, maximizing usefulness involves construing first a picture of agent-independent, objective matters of fact.

I argue for a new reading of Pyrrhonian beliefs inspired by representationalism (the content view) in recent philosophy of mind. I shall argue that there are two senses of acceptance or “acquiescence in something” (eudokein tini pragmati) rather than two senses of belief (doxa). For this reason, we can maintain along with Sextus that the Pyrrhonian skeptic behaves intentionally and can live his life in society adoxastôs without any proper beliefs whatsoever. However, the skeptical sense of acceptance is not (...) the mere avowal of a feeling or a mere report or register of the way things appear to me. I want to suggest the following reading. Acceptance without belief is an anti-predicative passive and involuntary acceptance of content by means of an indicator function (pathos or phainomenon) in virtue of the past regular connection between the representational content and the indicator function. The pathos (as a present state of mind) or the phainomenon “means” (that is, indicates) passively and involuntarily a content in virtue of its regular connection with this content through time. For example, the Pyrrhonian’s acceptance of the content of the sentence “there is fire” is based on the fact that he here and now perceives smoke and that pathos passively and involuntarily means (represents) the content that there is fire. There is no judgment involved at all: even when the skeptic suspends his judgment (epochê) about whether there is fire, his pathos makes him involuntarily accept that there is fire. That is what Sextus, following the Stoic tradition, calls “commemorative signs” (hupomnêstikon) in opposition to the so-called “indicative signs” (endeiktikon), namely the “internal assertion” of the content as a belief (as a propositional attitude). As I do not believe that any reasonable reading of the skeptical acceptance may be defended only by means of philological analysis and by the research of the huge doxography, my arguments deliberately mix historical evidence with reasons of a systematic nature. In this way, the defense of my alternative reading is abductive, namely as the inference to the best explanation. (shrink)

There’s a growing sense among philosophers of religion that Humean arguments from evil are some of the most formidable arguments against theism, and skeptical theism fails to undermine those arguments because they fail to make the inferences skeptical theists criticize. In line with this trend, Wes Morriston has recently formulated a Humean argument from evil, and his chief defense of it is that skeptical theism is irrelevant to it. Here I argue that skeptical theism is (...) relevant to Humean arguments. To do this, I reveal the common structure of skeptical theism’s critiques. Seeing the common structure reveals why some versions of skeptical theism are irrelevant to Humean arguments from evil. It also points the way forward to formulating a relevant version. By combining skeptical theism with a plausible principle concerning reasonable belief, I formulate a version of skeptical theism that undermines Morriston’s argument that is also immune from his objections.
