Ancient philosophy knew two main skeptical traditions: the Pyrrhonian and the Academic. In this final paper of the three‐part series devoted to ancient skepticism, I present some of the topics about Academic skepticism which have recently been much debated in the specialist literature. I will be concerned with the outlooks of Arcesilaus, Carneades, and Philo of Larissa.

Aenesidemus, the (re-)founder of Pyrrhonian skepticism, is usually said to have begun his career by breaking away from the Academy. This assertion rests on the word “συναιρεσιώτῃ” as it appears in Photius’ summary of Aenesidemus’ Pyrrhonian Discourses. I argue that Photius’ probable understanding of the Academy’s history undermines this traditional reading. I then examine the evidence external to Photius and conclude that it also speaks against the traditional narrative.

The point of departure of this paper is the striking similarities between the dispositions critical media literacy education aims to cultivate and the characteristics conspiracy theorists claim to embody. The golden question of critical literacy, “who benefits?” is in fact the central question of conspiracy theorists: “cui bono?” While critical media literacy educators teach learners to disrupt the common sense, to interrogate multiple viewpoints, to focus on sociopolitical issues, and to take actions and promote social justice, conspiracy theorists claim that (...) they do exactly those things. What I wish to illuminate through this juxtaposition, however, is not a way to clearly demarcate “critical” from “conspiratorial” theorizing, but is a question of educational desirability of skepticism. Skepticism in this paper is not understood as a classical epistemological question of the possibility of knowledge attainment, but as a form of vigilance toward epistemic authorities like the government, media, and academic institutions. Drawing on philosophy of conspiracy theories and political epistemology, I illuminate the problem of radical skepticism that characterizes some conspiracy theories and discuss the pivotal epistemic role of trust. Through this, I claim that critical media literacy education for democratic citizenship must strike a balance between cultivation of skepticism and building of trust toward epistemic authorities.

Peter Fosl's new monograph offers a bold reading of Hume as a "radical," "coherent," and "hybrid" skeptic, who draws influence from both the Pyrrhonian and Academic skeptical traditions. I press some concerns about whether Fosl's reading of Hume can accommodate his scientific ambitions.

The skeptical challenge to politics is that if knowledge is in short supply and it is a condition for the proper use of political power, then there is very little just politics. Cicero’s Republicanism is posed as a program for political legitimacy wherein both citizens and their states are far from ideal. The result is a form of what is termed negative conservatism, which shows political gridlock in a more positive light.

Immanuel Kant is a key thinker in the History of Western Philosophy whose ideas continue to fascinate contemporary English-speaking academic philosophers. One such idea is Kant's conception of transcendental arguments. Although these arguments do not originate in Kant's philosophy, Kant's conception of them occupies a special place in the English-speaking literature on the topic. A growing trend in this literature is to claim that Kant's transcendental arguments are unique because they aim to achieve an anti-skeptical end through deductive means. (...) I call the basic assumption behind readings of transcendental arguments like these the deductive/anti-skeptical assumption. This assumption claims that deduction is the best means to achieve an anti-skeptical end. In this thesis, I argue that accepting this assumption is one way to misinterpret transcendental arguments because—even though it seems compelling at first blush—it must be false. The resultant twist is that transcendental arguments cannot be deductive, which, in turn, means that understanding that Kant's transcendental arguments are not deductive in nature is itself no small detail for understanding the version of Kant's 'not-deductive' solution to skepticism developed here.

Pseudoskepticism, which typically is portraying someone's work as despicable with scientifically unsound polemics, is a modern day threat to the traditional standard of discussion in science and popular science. This essay gives seven tell-tale signs by which pseudoskepticism can be recognized.

Cicero’s "Academica" offers a particularly rich demonstration of how the unhappy dialectic between stoicism and skepticism engages Roman historical self-consciousness. The Hegelian thesis of philosophy as mediated through historical development is given a clear articulation in the “derivative” Romans, precisely through their reception of a tradition, their experience of philosophy as inseparable from the self-consciousness of historical relation. The dispute happening in the "Academica" between a dogmatic stoicism and academic skepticism thus directly echoes the problems of contemporary (...) 21st century philosophy insofar as the structures of the unhappy consciousness endure in the “academic” give and take between the authority of received doctrine (say, of mainstream post-classical analytic philosophy) and their subversion in skeptical critique.

We address some of the highlights of Augustine's thought, highlighting the author's philosophical themes. We will start with a presentation of Augustine`s biography and intellectual trajectory, and we will highlight some elements of its historical context, namely, the fragmentation of the Roman Empire and the nascent Christianity. We then address five philosophical problems that are part of the vast Augustinian discussion: 1) his critique of academic skepticism; 2) free will; 3) the problem of evil; 4) memory and time. (...) As an epilogue, 5) we approach the intertwined relationships between faith and reason in Augustinian thought. (shrink)

The work of Richard H. Popkin both introduced the concept of skeptical fideism and served to impressively document its importance in the philosophies of a diverse range of thinkers, including Montaigne, Pascal, Huet, and Bayle. Popkin’s landmark History of Scepticism, however, begins its coverage with the Renaissance. In this paper I explore the roots of skeptical fideism in ancient Greek and Roman philosophy, with special attention to Cicero’s De Natura Deorum, the oldest surviving text to clearly develop a skeptical fideist (...) perspective.

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.

As any fan of Leonard Cohen will tell you, many of his songs are deeply “philosophical,” in the sense that they deal reflectively and intelligently with the many of the basic issues of everyday human life, such as death, sex, love, God, and the meaning of life. It may surprise these same listeners to discover that much of academic philosophy (both past and present) has relatively little in common with this sort of introspective reflection, but is instead highly abstract, (...) methodologically complex, and filled with technical terminology that can make it inaccessible to anyone except specialists. This is not true of all philosophy, however, and Cohen’s focus on the immediate problems facing ordinary humans has much in common with the theories and ideas proposed by the Hellenistic philosophers who dominated the intellectual life of Greek- and Roman-influenced Europe for almost a thousand years. In this essay, I’ll use Cohen’s songs to examine the three major branches of Hellenistic thought: Stoicism (That’s No Way to Say Goodbye, If It Be Your Will), Epicureanism (Everybody Knows, Closing Time), and Skepticism (Famous Blue Raincoat, Different Sides).

Many people believe that philosophy makes no progress. Members of the general public often find it amazing that philosophers exist in universities at all, at least in research positions. Academics who are not philosophers often think of philosophy either as a scholarly or interpretative enterprise, or else as a sort of pre-scientific speculation. And many well-known philosophers argue that there is little genuine progress in philosophy. Daniel Stoljar argues that this is all a big mistake. When you think through exactly (...) what philosophical problems are, and what it takes to solve them, the pattern of success and failure in philosophy is similar to that in other fields. In philosophy, as elsewhere, there is a series of overlapping topics that determine what the subject is about. In philosophy, as elsewhere, different people in different historical epochs and different cultures ask different big questions about these topics. And in philosophy, as elsewhere, big questions asked in the past have often been solved: Stoljar provides examples. Philosophical Progress presents a strikingly optimistic picture of philosophy - not a radical optimism that says that there is some key that unlocks all philosophical problems, and not the kind of pessimism that dominates both professional and non-professional thinking about philosophy, but a reasonable optimism that views philosophy as akin to other fields.

Conspiracy theories are rather a popular topic these days, and a lot has been written on things like the meaning of _conspiracy theory_, whether it’s ever rational to believe conspiracy theories, and on the psychology and demographics of people who believe conspiracy theories. But very little has been said about why people might be led to posit conspiracy theories in the first place. This paper aims to fill this lacuna. In particular, I shall argue that, in open democratic societies, citizens (...) justifiably presuppose that the epistemic authorities—journalists, academics, scientists, and so on—are engaged in a good faith pursuit of the truth. This presupposition generates certain normative expectations on the behaviors of the epistemic authorities—they ought to be open to new evidence, possess a healthy degree of skepticism, be willing to engage with opponents, and so on. So, when an epistemic authority is presented with some putatively anomalous data or an alternative hypothesis for some event or phenomena, people expect the epistemic authority to respond in a way that is consonant with these norms. In some instances, however, the epistemic authorities do not respond in this way and instead are dogmatic, dismissive, and engage in _ad hominem_. From the point of view of the citizen, there’s a tension here between how the epistemic authorities ought to behave and how they have, in fact, behaved which is best resolved either by taking the epistemic authorities less seriously or by positing a conspiracy theory. Put another way, the failure of the epistemic authorities to adhere to the norms by which we take them to be governed when presented with apparent anomalies or alternative hypotheses is one reason for which one might initially posit a conspiracy theory.

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)

This book researches the thought of Jin Yuelin’s epistemology with some notions and methods of contemporary epistemology as the frame of reference. There are two kinds of academical significance in this book, one is that author has accurately comprehended the specific content, inadequacies and contradictions in Jin’ s epistemology, recognized the methods by which Jin Yuelin built his theory of knowledge. The other is that author has known about the differences in research objects and methods between Jin’s theory and contemporary (...) epistemology, and showed the position of Jin’s epistemology in the whole theory of knowledge through the comparative study. On the one hand, the book focuses on the core problem of Jin Yuelin’ epistemology that is how objective knowledge is produced. On the other hand, it is made up of seven chapters in accordance with the structure of Jin’s Theory of Knowledge. The first chapter introduces and comparatively analyzes the comprehensions about the concepts of “knowledge” and “epistemology” between Jin Yuelin and contemporary epistemologists. This chapter supplies the means and methods for following chapters. The second chapter describes Jin’s standpoint and criticism to idealism starting mode, analyzes the objective starting mode that belongs to Jin’s theory and reveals his negative attitude to skepticism. This chapter shows the essential characteristics of the Jin Yuelin’s epistemology. The given is the content of sensation, which is the most basic part of cognitive activity. Moreover Jin Yuelin regards sensation as foundation of knowledge, so the research on theory of the given is separated from the whole study of cognitive activity and treated as the third chapter, which presents Jin’s theory of the given and analyzes the problems of Jin’s theory, then introduces some kinds of theory of the given and theory of perception in the contemporary epistemology, finally comparatively investigates theories of the given between Jin Yuelin and contemporary epistemologists. From the perspective of cognitive activity, the fourth chapter describes the perceptual activity, the activity of knowing, the activity of thinking, means and outlines of reception in Jin’s epistemology, then exposes its contradictions and inadequacies; Induction is the important research object of the Western epistemologists, similarly Jin Yuelin paid more attention to induction and regards the principle of induction as outline of reception. In fact, his standpoint about the principle of induction is vital and creative, so the study of induction separately belongs to the fifth chapter. This chapter presents the Jin’s comprehension about the principle of induction and some answers to the problem of induction in contemporary epistemology, then comparatively analyzes two kinds of the thought about induction. The sixth chapter successively introduces being, nature and fact which all are objects of cognitive activity, then analyzes the problems within them. From the perspective of cognitive results, the last chapter presents the Jin’s standpoint about verification and demonstration of proposition, definition and criteria of truth, then simply describes the point views of contemporary epistemologists about verification and truth of proposition, finally comparatively investigates two kinds of thought. From the vertical, the thesis analyzes the fundamental sections of objective knowledge one by one, such as the given, experience, idea, proposition and truth. From the horizontal, the book focuses on the three main parts of knowledge event, for example, cognitive activity, objects of knowledge and the true proposition treated as knowledge. In a word, the whole book is coherent and organic unity. Through the comparative study, it can be concluded that it is reasonable for Jin Yuelin to enjoy a high academic status, because he is the first philosopher who specializes in the study of epistemology. At the same times, he improves transmission of logic, metaphysics and epistemology from the Western to China. So, his hard work enriches and expands the realm of Chinese philosophy. With the development of the study of epistemology, descriptive content of it, such as, perceptual activity and rational activity, will be regarded as the objects of psychology and cognitive science. Meanwhile, normative content will be retained. For example, analysis of conditions of knowledge, justification for belief claims, comprehension about the proofs of justification, as well as reactions to challenges of skepticism. The latter will continue to be objects of epistemology, of course, they must establish close relationships with psychology and cognitive science. According to this prospect, we should split Jin Yuelin’s theory of knowledge, of which the descriptive content would be allocated to psychology and cognitive science. On the contrary, the normative content would be kept as important resource for deeply studying epistemology. -/- Key words: Knowledge; Contemporary epistemology; Compare; The given; Idea; The principle of induction; Fact.

This paper briefly presents the historical and philosophical link between Enlightenment philosophy and the emergence of Postmodern philosophy, i.e., the transition from modernity to postmodernity. While identifying and recognizing the “difference” and the sharp contrast, I will concentrate on showing the “continuity” between the two philosophies. This paper shows that postmodernism can be understood as ultra-modernism in at least two dimensions 1) in opting for a particular critical methodology and 2) in the intensification of subjectivity. This enactment of deconstructive criticism, (...) skepticism, relativism, and subjectivism has generated a cultural condition that suspects and distrusts every knowledge and truth claim. As a result, the matters which are related to our shared communal concerns are becoming ambiguous. (shrink)

Naturalism, construed as the idea that philosophy should be continuous with science, is a highly influential view. Its consequences for epistemology, however, are rather odd. Many believe that naturalized epistemology allows eschewing traditional skeptical challenges. This is often seen as an advantage; but it also calls into question its claim of belonging to the philosophical inquiry into knowledge. This paper argues that skeptical challenges can be stated to defy epistemic optimism within naturalized epistemology, and that there are distinctively naturalistic forms (...) of skepticism. To that end, it outlines some assumptions underlying many attempts to naturalize epistemology. It contrasts these approaches to traditional epistemology and identifies the reasons offered by naturalistic epistemologists to dismiss traditional skeptical challenges. Next, it argues that the problem of skepticism can be sensibly stated within a naturalistic setting. Finally, it contends that there are distinctively naturalistic strategies to argue for skepticism and diagnoses the prospects of naturalism vis-à-vis these kinds of skeptical challenges. (shrink)

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.

There is a difference between the tasks of interpreting Sextus Empiricus and contesting his arguments. Usually, one does the latter relying on some version of the former. Though this seems obvious, it is easy to make mistakes in this endeavor. From this point, I draw two basic recommendations which we should follow, lest we take Sextus to hold implausible positions regarding his Five Modes. However, these recommendations lead us to interpret Sextus’ Pyrrhonism as a limited skepticism. In the final (...) section, as I suggest a counter-example to this commitment, I reconsider the notion of infinite (apeiron) in the Five Modes to better explain interpretation and criticism of Sextus’ arguments.

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’.

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)

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)

Moore and Russell thought that perceptual knowledge of the external world is based on abductive inference from information about our experience. Sosa maintains that this ‘indirect realist’ strategy has no prospects of working. Vogel disagrees and thinks it can and does work perfectly well, and his reasoning (and variations on that reasoning) seem initially promising, moreso than other approaches. My aim, however, will be to adjudicate this dispute in favor of Sosa’s pessimistic answer, and in doing so, to better uncover (...) the important role abductive inference does have in a wider theory of perceptual knowledge, even if it doesn’t feature in any promising vindication of (anti-skeptical) indirect realism.

Scholarship on ancient skepticism has undergone a remarkable renaissance in the last three decades. Specialists in ancient philosophy have explored the complex history of the Greco‐Roman skeptical traditions and discussed difficult philological and exegetical issues. But they have also assessed the philosophical significance of the various ancient skeptical outlooks. In this first paper, I provide a general presentation of this area of study, while in the two subsequent articles I will focus on some of the topics that have been (...) the object of much attention in the recent literature on ancient skepticism.

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.

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

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.

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.

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.

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.

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

This paper offers a new interpretation of Kant's relationship with skepticism in the Groundwork for the Metaphysics of Morals. My position differs from commonly held views in the literature in two ways. On the one hand, I argue that Kant's relationship with skepticism is active and systematic (contrary to Hill, Wood, Rawls, Timmermann, and Allison). On the other hand, I argue that the kind of skepticism Kant is interested in does not speak to the philosophical tradition in (...) any straightforward sense (contrary to Forster and Guyer). On my reading, Kant takes up a skeptical method in the Groundwork as a way of exposing certain obstacles in our ordinary and philosophical thinking about morality. The central obstacle he is interested in is practical in character, arising from a natural tendency we have to rationalize against the moral law. In attempting to resolve this tendency, I argue, the Groundwork turns out to have a profoundly educative task. (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.

In everyday life, we think of skepticism as the position of a stubborn person who has higher epistemic standards than others. Hence, the skeptic is someone who defends extravagant ideas. Some skeptics may deny that climate change is real, while others claim that the first moon landing did not take place. Contemporary philosophers think of skepticism in a different way. In their view, skepticism is the conclusion of a paradoxical argument about epistemic statuses like knowledge and reasons. (...) A paradoxical argument is a logically valid argument that, starting from seemingly plausible premises, reaches an absurd conclusion. We introduce two skeptical arguments. The regress argument purports to show that we lack reasons to believe any claim whatsoever because the search for those reasons inevitably leads to an infinite regress. The underdetermination argument seeks to prove that we lack reasons to believe that there are chairs, trees, other people, and so on; it supports that conclusion by citing skeptical hypotheses, including the idea that we might be dreaming (Descartes 1641) or the suggestion that we could be brains in a vat connected to a supercomputer that mimics the pattern of neural activity that would be produced if we were perceiving external objects (Putnam 1981).

Radical skepticism about the external world is founded on two assumptions: one is that the mind and the external world are logically independent; the other is that all our evidence for the nature of that world consists of facts about our minds. In this paper, I explore the option of denying the epistemic, rather than the logical assumption. I argue that one can do so only by embracing externalism about justification, or, after all, by rejecting the logical independence assumption. (...) Since (I argue) externalism is not a solution to the problem of skepticism, this means that skepticism is false only if the mind and the world are not logically independent. (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.

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.

It has been claimed that a key difference between ancient and contemporary skepticism is that, unlike the ancient skeptics, contemporary skeptics consider ordinary beliefs to be insulated from skeptical doubt. In the case of metaethics, this issue is related to the following question: what attitude towards ordinary moral thought and discourse should one adopt if one is a moral skeptic? Whereas moral abolitionists claim that one should do away with ordinary moral thought and discourse altogether, moral fictionalists maintain that, (...) given that morality produces practical benefits, one should continue to make moral utterances and have moral thoughts, while at the same time refraining from asserting such utterances and believing such thoughts. Focusing particularly on Mackie’s skeptical stance, the present essay considers whether the view that first-order moral beliefs are unaffected by moral skepticism is defensible, whether moral fictionalism is compatible with moral insulation, and whether contemporary moral skeptics are in general committed to there being insulation between first- and second-order levels.

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)

The paper defends the view that that a significant part of metaphysics should be understood as conceptual engineering, and explores its epistemological advantages and metaphysical implications. It discusses the challenge raised by moderate modal skepticism, which points out the lack of reliable methods for verifying modal statements through thought experiments. As I argue, a normative stance on metaphysical methodology, understanding it as engaging in conceptual engineering project, justifies the use of this method. By adopting an approach where the method (...) of cases offers reasons for adopting specific normative constraints on concept usage, the method becomes justifiable. Consequently, it can be employed to justify the revision of conceptual schemes and, in turn, validate certain modal claims about entities falling under the scrutinized concepts. The paper explores how this approach can methodologically enrich conceptual engineering-focused perspectives in metaphysics and examines its metaphysical consequences. In particular, it demonstrates that despite the mind-dependency of the method of cases results, it still leaves room for a metaphysically realistic viewpoint. (shrink)

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.

The theory of recognition arises within Hegel's confrontation with epistemological skepticism and aims at responding to the questions raised by modern skepticism concerning the accessibility of the external world, of other minds, and of one's own mind. This is possible to the extent that the theory of recognition is the guiding thread of a critique of the modern foundational theory of knowledge and, at the same time, the point of departure for an alternative approach. In this article I (...) will dwell on six stages of the evolution of Hegel's thought prior to the Phenomenology (1797-1806),stages shed great light on the direction taken by his argumentative strategy. Synthetically, the stages are as follows: 1. Hegel naturalizes the epistemological questions; 2. to do so he critiques foundationalism qua theory of empirical knowledge; 3. and qua theory of epistemic justification; 4. the critique of foundationalism is linked to a critique of the corresponding representationalistic theory of perception; 5. this, in turn, is linked to a critique of the monological theories of self-consciousness and to the development of a model of the rise of self-conscious knowing; 6. finally, Hegel synthesizes these epistemological views in a theory of knowledge qua recognition and in a metaphilosophical theory of philosophical rationality qua self-recognition: knowledge without foundation is thus the condition of possibility of philosophy’s self-justification.

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.

Academic social networks and social media have revolutionised the way individuals gather information and express themselves, particularly in academia, science, and research. Through the lens of academics, this study aims to investigate the epistemological and psychosocial aspects of these knowledge sources. The epistemological attitude model presented a framework to delve into and reflect upon the existence of knowledge sources, comprising subjective, interactional, and knowledge dimensions. One hundred and twenty-six university academics participated in this study, including lecturers and researchers from (...) different higher education institutions in Latvia. The study employed two methods: the Epistemological Attitudes towards Sources of Knowledge Questionnaire and the Epistemological Attitudes towards Sources of Knowledge Semantic Questionnaire. The data analysis involved several procedures, including exploratory and confirmatory factor analysis, correlation analysis, and test statistics. By implementing these methods, the study gained valuable insights into the sources of knowledge, examining them from two perspectives. The first perspective brought attention to the differences in academics’ appraisals by discussing their understanding, approach, use, and valuations of these sources. By scrutinising the constructs of meanings, the second perspective sheds light on the anticipated knowledge which is deemed ideal, the concrete knowledge that is both social and objective, and the subjectively valuable nature of academic social networks and social media. The findings underscore the specialised knowledge and qualities that academics rely on for producing knowledge. In terms of epistemology, methodology, social science, and education, the study holds theoretical and practical implications, especially in comprehending knowledge and its sources. (shrink)
