I offer a novel reading in this dissertation of René Descartes’s (1596–1650) skepticism in his work Meditations on First Philosophy (1641–1642). I specifically aim to answer the following problem: How is Descartes’s skepticism to be read in accordance with the rest of his philosophy? This problem can be divided into two more general questions in Descartes scholarship: How is skepticism utilized in the Meditations, and what are its intentions and relation to the preceding philosophical tradition? -/- I (...) approach the topic from both a historical and a text-based analysis, combining textual and contextual research. I examine Descartes’s skepticism against two main traditions in the historical analysis: philosophical skepticism and Aristotelian Scholasticism. I argue that skepticism in the Meditations is intended to oppose and upheave both Scholasticism and skepticism. The intended results of the work are not merely epistemological but also metaphysical and even ethical. Furthermore, these ambitions cannot be neatly distinguished but merge into each other. -/- The third historical context against which the skeptical meditations are examined is the literary genre of meditative exercises, particularly from the 1500–1600’s, which, while religiously and spiritually oriented, likewise provided the practitioner with an enlightened understanding of self-knowledge and their cognitive place in the world on the way to closer spiritual proximity to God. I argue by this reading that the skepticism of the Meditations is an attentive, meditational cognitive exercise that is not merely instrumental and methodological but is to have a genuine and serious (psychologically real) effect on our thinking. The skeptical meditation is not simply a theoretical thought experiment but is to be seriously practiced as a transformative process of reorienting one’s cognitive framework to discover truth, certainty, and a way to a happy, tranquil, and virtuous life. -/- I offer a close reading in the textual analysis of the first three meditations of the Meditations. I argue that the meditative skepticism employed in the work does not reject the previous beliefs but suspends judgment on them, withdrawing assent until further evidence can be found. I introduce a new term into Descartes scholarship in this analysis, based on the terminology of ancient skepticism: Cartesian epochē (gr. epochē, suspension, withdrawal). Instead of rejecting previous beliefs or assenting to the probably false, the skeptical procedure of the Meditations is argued to emulate in important ways the suspension of judgment on equally balanced reasons in ancient Pyrrhonian skepticism. Novel interpretations are presented along the way of the will’s freedom, of the First Meditation’s skeptical scenarios, of the cogito, and of the vindication of metaphysical certainty, as well as a clarification of the Cartesian Circle problem. -/- Reinterpreting the relation of Descartes’s skepticism to the preceding historical and literary traditions leads to a new look at the skeptical method itself. Presenting a new interpretation of skepticism in the Meditations leads at the same time to a new look at its relation to the historical context. The two research questions are, then, intrinsically tied together. -/- My focus in the study is on the Meditations, but I also reference and discuss Descartes’s other philosophical works, as well as his correspondence, when necessary.

This paper appeals to the phenomenon of dreaming to provide a novel defense against arguments from evil. The thrust of the argument is as follows: when we wake up after a nightmare we are often filled entirely with relief, and do not consider ourselves to have actually suffered very much at all; and since it is epistemically possible that this whole life is simply a dream, it follows that it is epistemically possible that in reality there is very little (...) suffering. This epistemic possibility decisively undermines a key premise of both logical and evidential arguments from evil. (shrink)

Jennifer Windt’s Dreaming is an enormously rich and thorough book, developing illuminating connections between dreaming, the methodology of psychology, and various philosophical subfields. I’ll focus on two epistemological threads that run through the book. The first has to do with the status of certain assumptions about dreams. Windt argues that the assumptions that dreams involve experiences, and that dream reports are reliable — are methodologically necessary default assumptions, akin to Wittgensteinian hinge propositions. I’ll suggest that Windt is quietly pre-supposing (...) some sceptical assumptions, and that recent literature in epistemic externalism may bear in important ways on her arguments. The second thread involves the perennial sceptical worry that dreaming threatens ordinary knowledge. I’ll suggest again that Windt makes tacit sceptical assumptions one may wish to resist. (shrink)

The relationship between Vietnam and China could be captured in the Chinese expression of “同床异梦”, which means lying on the same bed but having different dreams. The two countries share certain cultural and political similarities but also diverge vastly in their national interests. This paper adds to the extant literature on this topic by analyzing the element of trust/mistrust in their interactions in trade-investment, tourism, and defense-security. The analysis shows how the relationship is increasingly interdependent but is equally fragile due (...) to the lack of trust on both sides. The mistrust or even distrust of Chinese subjects run deep within the Vietnamese mindset, from the skepticism of Chinese investment, Chinese tourists, discrimination against ethnic Chinese, to the caution against Chinese aggression in the South China Sea. The paper forecasts that, despite the deep-seated differences and occasional mistrust, going forward, neither side would risk damaging the status quo even when tensions peak. (shrink)

Is ruling out the possibility that one is dreaming a requirement for a knowledge claim? In “Philosophical Scepticism and Everyday Life” (1984), Barry Stroud defends that it is. In “Others Minds” (1970), John Austin says it is not. In his defense, Stroud appeals to a conception of objectivity deeply rooted in us and with which our concept of knowledge is intertwined. Austin appeals to a detailed account of our scientific and everyday practices of knowledge attribution. Stroud responds that what Austin (...) says about those practices is correct in relation to the appropriateness of making knowledge claims, but that the skeptic is interested in the truth of those claims. In this paper, we argue that Stroud’s defense of the alleged requirement smuggles in a commitment to a kind of internalism, which asserts that the perceptual justification available to us can be characterized independently of the circumstances in which we find ourselves. In our reading of Austin, especially of Sense & Sensibilia, he rejects that kind of internalism by an implicit commitment to what is called today a “disjunctive” view of perception. Austin says that objectivity is an aspect of knowledge, and his disjunctivism is part of an explanation of why the alleged requirement is not necessary for a knowledge claim. Since both Stroud and Austin are committed to the objectivity of knowledge, Stroud may ask which view of perceptual knowledge is correct, whether the internalist or the disjunctive. We argue that by paying closer attention to what Austin says about our practices of knowledge attribution, one can see more clearly that it is grounded not only on a conception of objectivity, but also on a conception of ourselves as information agents, a conception that is as deeply rooted as that of the objectivity of knowledge. This gives us moral and practical reasons to favor the disjunctive view of perception. (shrink)

The Zhuangzi begins with Peng, a soaring bird transformed from a bounded fish, which is the first metaphor that points beyond limited standpoints to a higher point of view. The transformation is one-way and symbolizes that there is a higher viewpoint to attain which affords mental freedom and the clarity and scope of great vision. Under the alternate thesis of constant transformation, values and understandings must ceaselessly transform and collapse. All cyclical transformations must collapse into skeptical relativism and confusion. But (...) Peng does not turn back into a fish, and the awakened sage does not fall into a slumber of ignorance and confusion. It is only the thesis of a one-way transformation that leaves the sage in a state of knowledge. (shrink)

Review of Penelope Maddy, What Do Philosophers Do? Skepticism and the Practice of Philosophy (Oxford University Press, Oxford, 2017, 248 pp.).

Based on Pritchard’s distinction (2012, 2016) between favoring and discriminating epistemic grounds, and on how those grounds bear on the elimination of skeptical possibilities, I present the dream argument as a moderate skeptical possibility that can be reasonably motivated. In order to block the dream argument skeptical conclusion, I present a version of phenomenological disjunctivism based on Noë’s actionist account of perceptual consciousness (2012). This suggests that perceptual knowledge is rationally grounded because it is a form of embodied (...) achievement – what I call embodied rationality –, which offers a way of dissolving the pseudo-problem of epistemic immodesty, namely, the seemingly counterintuitive thesis that one can acquire rationally grounded knowledge that one is not in a radical skeptical scenario.

Some of the most enduring skeptical arguments invoke stories of deception -- the evil demon, convincing dreams, an envatted brain, the Matrix -- in order to show that we have no first-order knowledge of the external world. I confront such arguments with a dilemma: either (1) they establish no more than the logical possibility of error, in which case they fail to threaten fallible knowledge, the only kind of knowledge of the external world most of us think we have anyway; (...) or (2) they defeat themselves because they must grant us empirical knowledge or justified beliefs of the very kind they must also entirely deny us. Either way they pose no significant threat. (shrink)

This article discusses Margaret Cavendish's position on reality and fiction in dreams and her role within the moderate skepticism of her philosophy. While Cavendish argues that there is no distinction between dream-like and waking depictions, she does not consider the difference between fact and fiction to be sharp or relevant. We will argue that, although Cavendish promotes a philosophical discourse that articulates reason –that seeks to know reality— and fancy —which constructs fictions—, considers that only "elevated" poetic fantasies (...) are competent for the construction of this discourse.

Going about our daily lives in an orderly manner requires us, once we are aware of them, to dismiss many metaphysical possibilities. We take it for granted that we are not brains in vats, or living in the Matrix, or in an extended dream. Call these things that we take for granted “anti-skeptical assumptions”. What should a reflective agent who believes these things think of these beliefs? For various reasons, it can seem that we do not have evidence for (...) such anti-skeptical assumptions. Are anti-skeptical assumptions, then, beliefs that one may rationally hold without evidence for them – indeed, even in the face of a positive judgment that one lacks evidence for them? I survey and criticize some prominent answers to this question, and then offer a positive view that blends externalism about evidence with a mild, qualified kind of pragmatism. The view I offer aims to do justice to the sense that anti-skeptical assumptions are evidentially groundless while also maintaining that one cannot rationally believe something that one judges oneself to lack sufficient evidence for.

As I hope to show in this paper, Fichte’s rejection of traditional social contractarian accounts of human social relations is related to his rejection of the search for a criterion, or external standard, by which we might measure our knowledge in epistemology. More specifically, Fichte’s account of the impossibility of a normative social contract (as traditionally construed) is related to his account of the impossibility of our knowing things as they might be “in themselves,” separate from and independent of our (...) own activity in knowing them. Addressing the question of whether we finite human knowers can ever transcend the limits of our own consciousness, Fichte argues that Hume was not sufficiently critical: “…the Humean system holds open the possibility that we might someday be able to go beyond the boundary of the human mind, whereas the Critical system proves that such progress is absolutely impossible, and it shows that the thought of a thing possessing existence and specific properties in itself and apart from any faculty of representation is a piece of whimsy, a pipe dream, a nonthought.” In a very real sense, then, Fichte aims to “out-Hume” Hume on the question of whether we can ever know “things-in-themselves” or an external criterion for testing our knowledge. That is, Fichte goes beyond Hume and insists on the necessary – and not merely contingent – character of our ignorance of so-called things-in-themselves (i.e., things that supposedly exist antecedent to and independent of our consciousness of them). But unlike Hume, Fichte argues that radical skepticism regarding all possible knowledge of things-in-themselves does not undermine – but actually confirms and sustains – our belief in the emancipatory power of reason.

As a topic in the philosophy of psychology, dreaming is a fascinating, diverse, and severely underdeveloped area of study. The topic excites intense public interest in its own right, while also challenging our confidence that we know what the words “conscious” and “consciousness” mean. So dreaming should be at the forefront of our interdisciplinary investigations: theories of mind which fail to address the topic are incomplete. This chapter illustrates the tight links between conceptual and empirical issues by highlighting surprisingly deep (...) disagreements among leading dream scientists over what might seem basic aspects of their topic.

Skepticism about the internal world is actually more troubling than skepticism about the external world.

My principal objective in this essay will be to show that the widely held view that Hume's Treatise' is not significantly or "directly" concerned with problems of religion is seriously mistaken. I shall approach this issue by way of an examination of a major skeptical theme that runs throughout the Treatise; namely, Hume's skepticism regarding the powers of demonstrative reason. In this paper I shall be especially concerned to bring to light the full significance of this skeptical theme by (...) placing Hume's arguments in their appropriate historical context. I shall show that both Hume and his contemporaries recognized that these important skeptical arguments were aimed primarily against the dogmatic Christian rationalism of John Locke and above all Samuel Clarke, and that they were, therefore, well aware that these arguments had considerable theological significance.

A common objection to Sosa’s epistemology is that it countenances, in an objectionable way, unsafe knowledge. This objection, under closer inspection, turns out to be in far worse shape than Sosa’s critics have realised. Sosa and his defenders have offered two central response types to the idea that allowing unsafe knowledge is problematic: one response type adverts to the animal/reflective knowledge distinction that is characteristic of bi-level virtue epistemology. The other less-discussed response type appeals to the threat of dream (...) scepticism, and in particular, to the idea that many of our everyday perceptual beliefs are unsafe through the nearness of the dream possibility. The latter dreaming response to the safety objection to Sosa’s virtue epistemology has largely flown under the radar in contemporary discussions of safety and knowledge. We think that, suitably articulated in view of research in the philosophy and science of dreaming, it has much more going for it than has been appreciated. This paper further develops, beyond what Sosa does himself, the dreaming argument in response to those who think safety (as traditionally understood) is a condition on knowledge and who object to Sosa’s account on the grounds that it fails this condition. The payoffs of further developing this argument will be not only a better understanding of the importance of insights about dreaming against safety as a condition on knowledge, but also some reason to think a weaker safety condition, one that is relativised to SSS (i.e., skill/shape/situation) conditions for competence exercise, gets better results all things considered as an anti-luck codicil on knowledge.

The epistemological debate about radical skepticism has focused on whether our beliefs in apparently obvious claims, such as the claim that we have hands, amount to knowledge. Arguably, however, our concept of knowledge is only one of many knowledge-like concepts that there are. If this is correct, it follows that even if our beliefs satisfy our concept of knowledge, there are many other relevantly similar concepts that they fail to satisfy. And this might give us pause. After all, we (...) might wonder: What is so great about the concept of knowledge that we happen to have? Might it be more important, epistemically speaking, to investigate whether our beliefs satisfy some other relevantly similar concept instead? And how should questions such as these even be understood? This paper discusses the epistemological significance of these issues. In particular, a novel skeptical stance called ‘meta-skepticism’ is introduced, which is a kind of skepticism about the idea that some knowledge-like concepts are epistemically more important than others. It suggested that it is unclear whether this form of skepticism can be avoided. (shrink)

This paper outlines a new type of skepticism that is both compatible with fallibilism and supported by work in psychology. In particular, I will argue that we often cannot properly trust our ability to rationally evaluate reasons, arguments, and evidence (a fundamental knowledge-seeking faculty). We humans are just too cognitively impaired to achieve even fallible knowledge, at least for many beliefs.

Ephecticism is the tendency towards suspension of belief. Epistemology often focuses on the error of believing when one ought to doubt. The converse error—doubting when one ought to believe—is relatively underexplored. This essay examines the errors of undue doubt. I draw on the relevant alternatives framework to diagnose and remedy undue doubts about rape accusations. Doubters tend to invoke standards for belief that are too demanding, for example, and underestimate how farfetched uneliminated error possibilities are. They mistake seeing how incriminating (...) evidence is compatible with innocence for a reason to withhold judgement. Rape accusations help illuminate the causes and normativity of doubt. I propose a novel kind of epistemic injustice, for example, wherein patterns of unwarranted attention to farfetched error possibilities can cause those error possibilities to become relevant. Widespread unreasonable doubt thus renders doubt reasonable and makes it harder to know rape accusations. Finally, I emphasise that doubt is typically a conservative force and I argue that the relevant alternatives framework helps defend against pernicious doubt-mongers. (shrink)

Philosophy and Phenomenological Research, Volume 104, Issue 2, Page 434-453, March 2022.

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.

Keith DeRose’s solution to the skeptical problem is based on his indirect sensitivity account. Sensitivity is not a necessary condition for any kind of knowledge, as direct sensitivity accounts claim, but the insensitivity of our beliefs that the skeptical hypotheses are false explains why we tend to judge that we do not know them. The orthodox objection line against any kind of sensitivity account of knowledge is to present instances of insensitive beliefs that we still judge to constitute knowledge. This (...) objection line offers counter-examples against the claim of direct sensitivity accounts that sensitivity is necessary for any kind of knowledge. These examples raise an easy problem for indirect sensitivity accounts that claim that there is only a tendency to judge that insensitive beliefs do not constitute knowledge, which still applies to our beliefs that the skeptical hypotheses are false. However, a careful analysis reveals that some of our beliefs that the skeptical hypotheses are false are sensitive; nevertheless, we still judge that we do not know them. Therefore, the fact that some of our beliefs that the skeptical hypotheses are false are insensitive cannot explain why we tend to judge that we do not know them. Hence, indirect sensitivity accounts cannot fulfill their purpose of explaining our intuitions about skepticism. This is the hard problem for indirect sensitivity accounts. (shrink)

In this chapter, I present and explore various arguments for skepticism that are related to memory. My focus will be on the aspects of the arguments that are unique to memory, which are not shared, for example, by the more often explored skeptical arguments related to perception. -/- Here are some interesting upshots. First, a particular problem for justifiably concluding that one's memory is reliable is that any reasoning in favor of this conclusion will either result in epistemically circularity (...) or not be sufficient to justify the conclusion. Second, since many beliefs stored in memory do not appear to be based on evidence, it might also appear to follow that they are not justified. Third, although many stored memory beliefs are not based on stored memory experiences in the same way that perceptual beliefs are based on perceptual experiences, skeptical scenarios loom just as problematically for memory beliefs as they do for perceptual beliefs.

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.

Abstract Timothy Williamson has recently proposed to undermine modal skepticism by appealing to the reducibility of modal to counterfactual logic ( Reducibility ). Central to Williamson’s strategy is the claim that use of the same non-deductive mode of inference ( counterfactual development , or CD ) whereby we typically arrive at knowledge of counterfactuals suffices for arriving at knowledge of metaphysical necessity via Reducibility. Granting Reducibility, I ask whether the use of CD plays any essential role in a Reducibility-based (...) reply to two kinds of modal skepticism. I argue that its use is entirely dispensable, and that Reducibility makes available replies to modal skeptics which show certain propositions to be metaphysically necessary by deductive arguments from premises the modal skeptic accepts can be known.

In this paper I distinguish two ways of raising a sceptical problem of others' minds: via a problem concerning the possibility of error or via a problem concerning sources of knowledge. I give some reason to think that the second problem raises a more interesting problem in accounting for our knowledge of others’ minds and consider proposed solutions to the problem.

It has recently been argued that indeterminacy and indeterminism make most ordinary counterfactuals false. I argue that a plausible way to avoid such counterfactual skepticism is to postulate the existence of primitive modal facts that serve as truth-makers for counterfactual claims. Moreover, I defend a new theory of ‘might’ counterfactuals, and develop assertability and knowledge criteria to suit such unobservable ‘counterfacts’.

Cognitive theories claim, whereas non-cognitive theories deny, that cognitive access is constitutive of phenomenology. Evidence in favor of non-cognitive theories has recently been collected by Block and is based on the high capacity of participants in partial-report experiments compared to the capacity of the working memory. In reply, defenders of cognitive theories have searched for alternative interpretations of such results that make visual awareness compatible with the capacity of the working memory; and so the conclusions of such experiments remain controversial. (...) Instead of entering the debate between alternative interpretations of partial-report experiments, this paper offers an alternative line of research that could settle the discussion between cognitive and non-cognitive theories of consciousness. Here I relate the neural correlates of cognitive access to empirical research into the neurophysiology of dreams; cognitive access seems to depend on the activity of the dorsolateral prefrontal cortex. However, that area is strongly deactivated during sleep; a period when we entertain conscious experiences: dreams. This approach also avoids the classic objection that consciousness should be inextricably tied to reportability or it would fall outside the realm of science. (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.

Though ancient Pyrrhonian skepticism is apparently based on disagreement, this aspect of skepticism has been widely neglected in contemporary discussion on skepticism. The paper provides a rational reconstruction of the skeptical argument from disagreement that can be found in the books of Sextus Empiricus. It is argued that this argument forms a genuine skeptical paradox that has no fully satisfactory resolution. All attempts to resolve it make knowledge or justified belief either intuitively too easy or impossible.

In Meditations on First Philosophy, René Descartes argues that one cannot trust one’s senses since they are not a reliable source of obtaining knowledge of the world. One of Descartes’s main contentions to support such an argument is from his explanation of dreams, where one can feel one is awake but instead one is dreaming. Native Americans, however, may argue that the experiences one has in dreams are real and are a source of knowledge of the real world. Although Descartes (...) uses dreams to support his argument, some Native Americans have a different take on dreams. Dreams for Native Americans are a source of knowledge as well as a source for obtaining one’s identity. Gregory Cajete, in American Indian Thought, notes that “Dreams and Visions are a natural means for accessing knowledge and establishing relationship to the world. They are encouraged and facilitated.” In other words, it is through dreams that individuals are guided, destined, and informed. Therefore, dreams as understood by some Native Americans are an extension of reality that anticipate events that will happen or can happen. The focus of this paper is an exploration of the philosophical and religious epistemology pertaining to Native Americans as described in their accounts of dreams. (shrink)

The fact that philosophy is systematic—that philosophical issues are thoroughly interconnected—was a commonplace among nineteenth century idealists, then neglected by analytic philosophers throughout much of the twentieth century, and has now finally started to get some renewed attention. But other than calling attention to the fact, few philosophers have tried to say what it consists in, or what its implications are. -/- I argue that the systematicity of philosophy has disastrous epistemological implications. In particular, it implies philosophical skepticism: philosophers (...) are rationally prohibited from believing any philosophical thesis. The argument goes by way of a new principle that connects inquiry with what is rational to believe. I conclude with a discussion of the relationship between my argument and other, more well-trodden arguments for philosophical skepticism. (shrink)

Empirical work on motivated reasoning suggests that our judgments are influenced to a surprising extent by our wants, desires and preferences (Kahan 2016; Lord, Ross, and Lepper 1979; Molden and Higgins 2012; Taber and Lodge 2006). How should we evaluate the epistemic status of beliefs formed through motivated reasoning? For example, are such beliefs epistemically justified? Are they candidates for knowledge? In liberal democracies, these questions are increasingly controversial as well as politically timely (Beebe et al. 2018; Lynch forthcoming, 2018; (...) Slothuus and de Vreese 2010). And yet, the epistemological significance of motivated reasoning has been almost entirely ignored by those working in mainstream epistemology. We aim to rectify this oversight. Using politically motivated reasoning as a case study, we show how motivated reasoning gives rise to three distinct kinds of skeptical challenges. We conclude by showing how the skeptical import of motivated reasoning has some important ramifications for how we should think about the demands of intellectual humility. (shrink)

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.

This chapter serves as an opinionated introduction to the problem of convergence (that there is no clear convergence to the truth in philosophy) and the problem of peer disagreement (that disagreement with a peer rationally demands suspending one’s beliefs), and some of the issues they give rise to, namely, philosophical skepticism and progress in philosophy. After introducing both topics and surveying the various positions in the literature we explore the prospects of an alternative, hinge-theoretic account.

Deepfakes are audio, video, or still-image digital artifacts created by the use of artificial intelligence technology, as opposed to traditional means of recording. Because deepfakes can look and sound much like genuine digital recordings, they have entered the popular imagination as sources of serious epistemic problems for us, as we attempt to navigate the increasingly treacherous digital information environment of the internet. In this paper, I attempt to clarify what epistemic problems deepfakes pose and why they pose these problems, by (...) drawing parallels between recordings and our own senses as sources of evidence. I show that deepfakes threaten to undermine the status of digital recordings as evidence. The existence of deepfakes thus encourages a kind of skepticism about digital recordings that bears important similarities to classic philosophical skepticism concerning the senses. However, the skepticism concerning digital recordings that deepfakes motivate is also importantly different from classical skepticism concerning the senses, and I argue that these differences illuminate some possible strategies for solving the epistemic problems posed by deepfakes.

In this paper, I argue that the topic of skepticism is central to Hegel’s philosophical work. However, I contend that in returning to the subject of skepticism throughout his career, Hegel does not treat skepticism simply as an epistemological challenge to be overcome on the way to truth, as some commentators suggest, but as part of the very truth which it is philosophy’s task to explain. I make this case by considering three texts through which Hegel develops (...) the connection between skepticism and the ‘negative’ or ‘dialectical’ dimension of reality: “Relationship of Skepticism to Philosophy” (1802), the Phenomenology of Spirit (1807), and the Encyclopedia Logic (1817). In this, I also demonstrate how the topic of skepticism informs the development of Hegel’s speculative metaphysics throughout his career and, thus, present a problematic that sheds light on the important continuity between these different phases of Hegel’s project.

There are many different oughts. There is a moral ought, a prudential ought, an epistemic ought, the legal ought, the ought of etiquette, and so on. These oughts can prescribe incompatible actions. What I morally ought to do may be different from what I self-interestedly ought to do. Philosophers have claimed that these conflicts are resolved by an authoritative ought, or by facts about what one ought to do simpliciter or all-things-considered. However, the only coherent notion of an ought simpliciter (...) has preposterous first-order normative commitments. It is more reasonable to reject the ought simpliciter in favor of the form of normative pluralism advocated in (Tiffany 2007). (shrink)

Skeptics argue that the acquisition of knowledge is impossible given the standing possibility of error. We present the limiting convergence strategy for responding to skepticism and discuss the relationship between conceivable error and an agent’s knowledge in the limit. We argue that the skeptic must demonstrate that agents are operating with a bad method or are in an epistemically cursed world. Such demonstration involves a significant step beyond conceivability and commits the skeptic to potentially convergent inquiry.

This paper considers two novel Bayesian responses to a well-known skeptical paradox. The paradox consists of three intuitions: first, given appropriate sense experience, we have justification for accepting the relevant proposition about the external world; second, we have justification for expanding the body of accepted propositions through known entailment; third, we do not have justification for accepting that we are not disembodied souls in an immaterial world deceived by an evil demon. The first response we consider rejects the third intuition (...) and proposes an explanation of why we have a faulty intuition. The second response, which we favor, accommodates all three intuitions; it reconciles the first and the third intuition by the dual component model of justification, and defends the second intuition by distinguishing two principles of epistemic closure.

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.

Thought experiments involving The Matrix, brains-in-vats, or Cartesian demons have traditionally thought to describe skeptical possibilities. Chalmers has denied this, claiming that the simulations involved are real enough to at least sometimes defeat the skeptic. Through an examination of the meaning of kind terms in natural language I argue that, though the Chalmers view may be otherwise attractive, it is not an antidote to skepticism.
