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)

I show that some of the most initially attractive routes of refuting epistemological solipsism face serious obstacles. I also argue that for creatures like ourselves, solipsism is a genuine form of external world skepticism. I suggest that together these claims suggest the following morals: No proposed solution to external world skepticism can succeed which does not also solve the problem of epistemological solipsism. And, more tentatively: In assessing proposed solutions to external world skepticism, epistemologists should explicitly consider (...) whether those solutions extend to knowledge of other minds. Finally, and also tentatively: epistemological solipsism warrants more philosophical attention than it currently enjoys. (shrink)

Philosophers disagree. A lot. Pervasive disagreement is part of the territory; consensus is hard to find. Some think this should lead us to embrace philosophical skepticism: skepticism about the extent to which we can know, or justifiably believe, the philosophical views we defend and advance. Most philosophers in the literature fall into one camp or the other: philosophical skepticism or philosophical anti-skepticism. Drawing on the insights of hinge epistemology, this paper proposes another (...) way forward, an intermediate position that appeals both to skeptical and anti-skeptical intuitions concerning the possibility and scope of philosophical knowledge. The main advantage of our account is that it’s able to recover some philosophical knowledge while also being compatible with philosophical skepticism. (shrink)

In Wittgenstein on Rules and Private Language, Saul Kripke presents a controversial skeptical argument, which he attributes to Wittgenstein’s interlocutor in the Philosophical Investigations [PI]. The argument purports to show that there are no facts that correspond to what we mean by our words. Kripke maintains, moreover, that the conclusion of Wittgenstein’s so-called private language argument is a corollary of results Wittgenstein establishes in §§137-202 of PI concerning the topic of following-a-rule, and not the conclusion of an independently developed (...) argument in §§243ff of PI, as most commentators take it to be. In this work, I assess Kripke’s skeptical argument both in its own right, and as an interpretation of the rule-following sections of PI. In its own right, I try to show that it is critically flawed. However, as an interpretation of the rule-following sections of PI, I try to show that it is essentially correct. I do this by showing that Kripke’s interpretation squares with and supports the meta-philosophical framework developed by Wittgenstein in §§107-136 of PI, which immediately precedes his remarks on following-a-rule.

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

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.

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)

G.E. Moore’s writings on external world skepticism show us, in broad outline, how to dispense with external world skepticism in a way that is satisfying, intellectually responsible, and yet avoids engaging in constructive epistemological theory-building altogether. His work thus reveals something very important about the relation between epistemology and ordinary life, and also about what it would take to reach a satisfying resolution of certain sorts of perennial philosophical problems.

Humans are obsolete. In the post-ChatGPT era, artificial intelligence systems have replaced us in the last sectors of life that we thought were our personal kingdom. Yet, humans still have a place in this life. But they can find it only if they forget all those things that we believe make us unique. Only if we go back to doing nothing, can we truly be alive and meet our Self. Only if we stop thinking can we accept the Cosmos as (...) it is and know what Being is. Only if we become irrational can we ever understand what AI will never understand. Humans need to destroy what they have created, because in the world they have built they have no place. Unless we become children once more. And laugh for no reason. In a cosmos that was meant to be our home. (shrink)

The scientific community, we hold, often provides society with knowledge—that the HIV virus causes AIDS, that anthropogenic climate change is underway, that the MMR vaccine is safe. Some deny that we have this knowledge, however, and work to undermine it in others. It has been common to refer to such agents as “denialists”. At first glance, then, denialism appears to be a form of skepticism. But while we know that various denialist strategies for suppressing belief are generally effective, little (...) is known about which strategies are most effective. We see this as an important first step toward their remediation. This paper leverages the approximate comparison to various forms of philosophical skepticism to design an experimental test of the efficacy of four broad strategies of denial at suppressing belief in specific scientific claims. Our results suggest that assertive strategies are more effective at suppressing belief than questioning strategies. (shrink)

Illusionism treats the almost universally held belief in our ability to make free choices as an erroneous, though beneficent, idea. According to this view, it is sadly true, though virtually impossible to believe, that none of a person’s choices are avoidable and ‘up to him’: any claim to the effect that they are being naïveté or, in the case of those who know better, pretense. Indeed, the implications of this skepticism are so disturbing, pace Spinoza, that it must not (...) be allowed to see the light of intellectual day, confined to the nether regions of consciousness. Even those who have ‘done the philosophy’ and disabused themselves here should nevertheless (somehow) continue believing in free will, lest they come to regard our lives as meaningless, spreading despair and social upheaval. Thus, the “Illusionists” who propound this view are themselves circumspect in doing so. -/- But is escaping the (putative) truth really possible here? Could a disabused philosopher ever return to something like his former intellectual innocence? Self-deception may not be possible; but would an attempt at it reveal anything significant about choice formation? If one were to try to regain one’s illusion, what would one realize? I shall argue here that one would reflectively discover precisely the opposite of what the Illusionists contend- that there are indeed free choices. Let us begin by considering the inconsistency that supposedly entails the illusion of free will. (shrink)

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).

One of the most basic methods of philosophy is, and has always been, the consideration of counterfactual cases and imaginary scenarios. One purpose of doing so obviously is to test our theories against such counterfactual cases. Although this method is widespread, it is far from being commonly accepted. Especially during the last two decades it has been confronted with criticism ranging from complete dismissal to denying only its critical powers to a cautious defense of the use of thought experiments as (...) counterexamples. One of the strongest criticisms of the method of thought experimentation is "modal skepticism" as explicated and defended by Peter van Inwagen. Van Inwagen argues that the philosopher's notion of logical possibility is confused and that its epistemology is dubious. I argue that van Inwagen's skepticism is unwarranted. There is a sufficiently clear notion of logical possibility and a sufficiently straightforward way of getting to know what is logically possible. In the remainder of the paper I show how that connects with the methodology of thought experimentation in philosophy. (shrink)

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.

Philosophical skepticism, according to numerous influential accounts of it, is bound up with our failure or inability to adopt an “absolute” standpoint. Similarly, many religions speak of an “absolute” that also is beyond human reach. With this similarity in mind, I will develop what I take to be a religious dimension of skepticism. First, I will discuss the connection that Stanley Cavell draws between his reading of skepticism and the notions of God and original sin. I (...) will then refer to William James’s description of the religious experience of conversion and apply it to the transformative aspect of skepticism. Finally, I will argue with respect to mysticism and negative theology that the transformative experiences one can find in both skepticism and religion can be interpreted as yielding an experiential understanding of the finitude of the human condition. (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.

The meta-ethical commitments of folk respondents – specifically their commitment to the objectivity of moral claims – have recently become subject to empirical scrutiny. Experimental findings suggest that people are meta-ethical pluralists: There is both inter- and intrapersonal variation with regard to people’s objectivist commitments. What meta-ethical implications, if any, do these findings have? I point out that current research does not directly address traditional meta-ethical questions: The methods used and distinctions drawn by experimenters do not (...) perfectly match those of meta-ethicists. However, I go on to argue that, in spite of this mismatch, the research findings should be of interest to moral philosophers, including meta-ethicists. Not only do these findings extend the field of moral psychology with new data and hypotheses, but they also provide tentative evidence that touches on the adequacy of theses in moral semantics and moral metaphysics. Specifically, they put pressure on argum... (shrink)

An apparently increasing number of philosophers take free will skepticism to pose a serious challenge to some of our practices. This must seem odd to many—why should anyone think that free will skepticism is relevant for our practices, when nobody seems to think that other canonical forms of philosophical skepticism are relevant for our practices? Part of the explanation may be epistemic, but here I focus on a metaethical explanation. Free will skepticism is special because (...) it is compatible with ‘basic moral reasons’—moral reasons acknowledged by all mainstream ethicists—and other minds and induction skepticism are not. One example is our reason not to intentionally harm others. Practical seriousness about other minds and induction skepticism undermines this reason, but practical seriousness about free will skepticism only undermines a potential overrider of this reason, that is, the reason of retribution.

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.

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.

Many philosophers have been attracted to a restricted version of the principle of indifference in the case of self‐locating belief. Roughly speaking, this principle states that, within any given possible world, one should be indifferent between different hypotheses concerning who one is within that possible world, so long as those hypotheses are compatible with one's evidence. My first goal is to defend a more precise version of this principle. After responding to several existing criticisms of such a principle, I argue (...) that existing formulations of the principle are crucially ambiguous, and I go on to defend a particular disambiguation of the principle. According to the disambiguation I defend, how we should apply this restricted principle of indifference sensitively depends on our background metaphysical beliefs. My second goal is to apply this disambiguated principle to classical skeptical problems in epistemology. In particular, I argue that Eternalism threatens to lead us to external world skepticism, and Modal Realism threatens to lead us to inductive skepticism. (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)

Philosophical theories of explanation characterize the difference between correct and incorrect explanations. While remaining neutral as to which of these ‘first-order’ theories is right, this paper asks the ‘meta-explanatory’ question: is the difference between correct and incorrect explanation real, i.e., objective or mind-independent? After offering a framework for distinguishing realist from anti-realist views, I sketch three distinct paths to explanatory anti-realism.

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.

We distinguish and discuss two different accounts of the subject matter of theories of reference, meta-externalism and meta-internalism. We argue that a form of the meta- internalist view, “moderate meta-internalism”, is the most plausible account of the subject matter of theories of reference. In the second part of the paper we explain how this account also helps to answer the questions of what kind of concept reference is, and what role intuitions have in the study of (...) the reference relation.

The human soul has been believed to be immaterial and immortal element which exclusively inheres in the human body. Ukpugho ukpong (soul transplant) is an ancient meta-medical science of the Annang and Ibibio people, which is hinged on the belief that the human soul is transcendent and it exclusively inheres in proxy animal; that the soul is mortal, and can be surgically transplanted in the likeness of somatic tissue transplant. This study aimed at carrying out a philosophical critique (...) of this belief in order to determine its significance as a metaphysical concept. It also aimed at critically examining the philosophical as well as sociological discussions on the subject of ukpuho ukpong. The study was discussed on the framework of African concept of mind which holds that the soul has dual nature, namely – the Active Principle and the Quiescent Counterpart. The paper debunks the doctrines of metempsychosis and transmigration as alien to African metaphysics. The method of ordinary language analysis was employed to analyze the concepts ukpong and mbukpong. In conclusion, the paper made the following observations that: the soul is transcendent but perishable substance, the mind has dual nature, the soul does not transmigrate and the science of ukpuho ukpong is not a pseudo-metaphysical concept but was founded on African logic of dualistic mind. The paper notes that the science of ukpuho ukpong is bugged with a number of unresolved philosophical problems. Despite that the paper discovered that the science of ukpuho ukpong can contribute significantly to meta-medicine and sustainable environmental values. (shrink)

Radical skepticism relies on the hypothesis that one could be completely cut off from the external world. In this paper, I argue that this hypothesis can be rationally motivated by means of a conceivability argument. Subsequently, I submit that this conceivability argument does not furnish a good reason to believe that one could be completely cut off from the external world. To this end, I show that we cannot adequately conceive scenarios that verify the radical skeptical hypothesis. Attempts to (...) do so fall prey to one or another of three pitfalls: they end up incomplete, reveal a deep contradiction or recreate a non-skeptical hypothesis. I use these results to improve upon Pritchard’s recent attempt at undercutting radical skepticism. (shrink)

How, if at all, consciousness can be part of the physical universe remains a baffling problem. This article outlines a new, developing philosophical theory of how it could do so, and offers a preliminary mathematical formulation of a physical grounding for key aspects of the theory. Because the philosophical side has radical elements, so does the physical-theory side. The philosophical side is radical, first, in proposing that the productivity or dynamism in the universe that many believe to (...) be responsible for its systematic regularities is actually itself a physical constituent of the universe, along with more familiar entities. Indeed, it proposes that instances of dynamism can themselves take part in physical interactions with other entities, this interaction then being “meta-dynamism” (a type of meta-causation). Secondly, the theory is radical, and unique, in arguing that consciousness is necessarily partly constituted of meta-dynamic auto-sensitivity, in other words it must react via meta-dynamism to its own dynamism, and also in conjecturing that some specific form of this sensitivity is sufficient for and indeed constitutive of consciousness. The article proposes a way for physical laws to be modified to accommodate meta-dynamism, via the radical step of including elements that explicitly refer to dynamism itself. Additionally, laws become, explicitly, temporally non-local in referring directly to quantity values holding at times prior to a given instant of application of the law. The approach therefore implicitly brings in considerations about what information determines states. Because of the temporal non-locality, and also because of the deep connections between dynamism and time-flow, the approach also implicitly connects to the topic of entropy insofar as this is related to time.

Many classically valid meta-inferences fail in a standard supervaluationist framework. This allegedly prevents supervaluationism from offering an account of good deductive reasoning. We provide a proof system for supervaluationist logic which includes supervaluationistically acceptable versions of the classical meta-inferences. The proof system emerges naturally by thinking of truth as licensing assertion, falsity as licensing negative assertion and lack of truth-value as licensing rejection and weak assertion. Moreover, the proof system respects well-known criteria for the admissibility of inference rules. (...) Thus, supervaluationists can provide an account of good deductive reasoning. Our proof system moreover brings to light how one can revise the standard supervaluationist framework to make room for higher-order vagueness. We prove that the resulting logic is sound and complete with respect to the consequence relation that preserves truth in a model of the non-normal modal logic _NT_. Finally, we extend our approach to a first-order setting and show that supervaluationism can treat vagueness in the same way at every order. The failure of conditional proof and other meta-inferences is a crucial ingredient in this treatment and hence should be embraced, not lamented. (shrink)

In his early writings, Kant says that the solution to the puzzle of how morality can serve as a motivating force in human life is nothing less than the “philosophers’ stone.” In this dissertation I show that for years Kant searched for the philosophers’ stone in the concept of “respect” (Achtung), which he understood as the complex effect practical reason has on feeling. -/- I sketch the history of that search in Chapters 1-2. In Chapter 3 I show that Kant’s (...) analysis in Groundwork I is incomplete because it does not explain how respect functions as a feeling in motivating choice. In Chapter 4 I argue that Kant’s subsequent attempt to sidestep this explanation in Groundwork III is unsuccessful, and that his position remains open to a skeptical threat. The argument in the second Critique, which I reconstruct in Chapters 5-6, overcomes this threat, and in doing so explains how the feeling of respect is both painful and pleasurable. -/- In the course of defending these claims, I provide an alternative reading of the shift in Kant’s ethical project from the Groundwork of 1785 to the second Critique of 1788 Against a common view in the literature, I argue that the shift does not concern the direction of Kant’s deduction (from freedom to morality, or morality to freedom); rather, it concerns his view of human sensibility and the resources he thinks we have to make our practical self-understanding intelligible. In the second Critique, I argue, Kant develops a novel approach to moral feeling from the perspective of the human agent; and this in turn clears room in his ethics for a new kind of a priori knowledge—namely, knowledge of what the activity of practical reason must feel like. By way of conclusion, I offer a few reasons for why the form of Kant’s argument in the second Critique is still relevant today, as it shows why we can only address moral skepticism from a first-personal perspective.

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.

ABSTRACT Traditionally, being a realist about something means believing in the independent existence of that something. In this line of thought, a scientific realist is someone who believes in the objective existence of the entities postulated by our best scientific theories. In metaphysical terms, what does that mean? In ontological terms, i.e., in terms of what exists, scientific realism can be understood as involving the adoption of a scientifically informed ontology. But according to some philosophers, a realistic attitude must go (...) beyond ontology. The way in which this requirement has been understood involves providing a metaphysics for the entities postulated by science, that is, answering questions about the nature of what ontology admits to exist. We discuss how two fashionable approaches face the challenge of providing a metaphysics for science: a form of naturalism and the Viking/Toolbox approach. Finally, we present a third way, which adopts the best of both approaches: the meta-Popperian method, which focuses on discarding the wrong alternatives, or better saying, the metaphysical profiles incompatible with certain theories. We present the meta-Popperian method, a metametaphysical method capable of objectively assessing which metaphysical profiles are incompatible with certain scientific theories. For this, we will use quantum mechanics as a case study, presenting some previously obtained results. As our focus is on methodological questions about the relationship between metaphysics and science; with this method, we can see how science can be used to avoid error in metaphysical issues. In our opinion, this would be a way to develop a productive relationship between science and metaphysics. (shrink)

Michael WiIliams maintains that skepticism about the extemal worId is vitiated by a commitment to foundationalism and epistemological realism. (The latter is, approximately, the view that there is such a thing as knowledge of the extemal world in general, which the skeptic can take as a target). I argue that skepticism is not encumbered in the ways Williams supposes. What matters, first of all, is that we can’t perceive the difference between being in an ordinary environment and being (...) in the sort of situation the skeptic describes (e.g. having one’s brain manipulated by deceitful experimenters). This point can be upheld without embracing any substantial foundationalist tenet, such as the existence of basic beliefs, the availabiIity of something “given,” or the epistemic priority of experience. As to “epistemological realism,” I find that Williams has offered no principled way to distinguish between ordinary chaIIenges to knowledge and skeptical challenges which, supposedly, have no cIaim on our concem.

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)

In this paper, we describe four broad ‘meta-methods’ employed in scientific and philosophical research of qualia. These are the theory-centred metamethod, the property-centred meta-method, the argument-centred meta-method, and the event-centred meta-method. Broadly speaking, the theory-centred meta-method is interested in the role of qualia as some theoretical entities picked out by our folk psychological theories; the property-centred meta-method is interested in some metaphysical properties of qualia that we immediately observe through introspection ; the argument-centred (...) meta-method is interested in the role of qualia in some arguments for non-physicalism; the event-centred metamethod is interested in the role of qualia as some natural events whose nature is hidden and must be uncovered empirically. We will argue that the event-centred metamethod is the most promising route to a comprehensive scientific conception of qualia because of the flexibility of ontological and methodological assumptions it can provide. We also reveal the hidden influences of the different meta-methods and in doing so show why consideration of meta-methods has value for the study of consciousness. (shrink)

A recent, seemingly appealing version of the powerful qualities view defines properties’ qualitativity via an essentialist claim and their powerfulness via a grounding claim. Roughly, this approach holds that properties are qualities because they have qualitative essences, while they are powerful because their instances or essences ground causal-modal facts. I argue that this theory should be replaced with one that defines the powerfulness of qualities in terms of both a grounding claim and a ‘meta-grounding’ claim. Specifically, I formulate and (...) defend a view on which qualities are powerful just if instances of those qualitiesat least partiallyground dispositionsin virtue of the essences of those qualities.

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 (...) class='Hi'>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)

Four issues or problems philosophers should be concerned about when doing philosophy.

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.

This paper excavates the practice-oriented background and therapeutic significance of emptiness in the Madhyamaka philosophy attributed to Nāgārjuna and Sengzhao. Buddhist emptiness unravels experiential and linguistic reification through meditation and argumentation. The historical contexts and uses of the word indicate that it is primarily a practical diagnostic and therapeutic concept. Emptiness does not lead to further views or truths but, akin to yet distinct from Ajñāna and Pyrrhonian skepticism, the suspension of assertion. This sense of emptiness as a practice (...) can be traced in the intercultural transmission of Madhyamaka from Nāgārjuna, its paradigmatic philosopher, to Sengzhao 僧肇, its first pivotal indigenous Chinese representative.

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.

This paper offers a critical reconstruction of Thomas Nagel’s principal arguments in metaphysics, epistemology, philosophy of mind, ethics and political philosophy.

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.

Review of What do Philosophers Do? Skepticism and the Practice of Philosophy by Penelope Maddy.

Attempting to compare scientific theories requires a philosophical model of meaning. Yet different scientific theories have at times—particularly in early chemistry—pre-supposed disparate theories of meaning. When two theories of meaning are incommensurable, we must say that the scientific theories that rely upon them are meta-incommensurable. Meta- incommensurability is a more profound sceptical threat to science since, unlike first-order incommensurability, it implies complete incomparability.

Eliminative reasoning is a method that has been employed in many significant episodes in the history of science. It has also been advocated by some philosophers as an important means for justifying well-established scientific theories. Arguments for how eliminative reasoning is able to do so, however, have generally relied on a too narrow conception of evidence, and have therefore tended to lapse into merely heuristic or pragmatic justifications for their conclusions. This paper shows how a broader conception of evidence not (...) only can supply the needed justification but also illuminates the methodological significance of eliminative reasoning in a variety of contexts.

The main claim of this essay is that knowledge is no more
valuable than lasting true belief.
This claim is surprising. Doesn't knowledge have a unique
and special value? If the main claim is correct and if, as it seems,
knowledge is not lasting true belief, then knowledge does not have a unique value:
in whatever way knowledge is valuable, lasting true belief is just as valuable.
However, this result does not show that knowledge is worthless, nor does it undermine
our knowledge gathering practices. There (...) is, rather, a positive philosophical payoff:
skepticism about knowledge is defused. Assuming one can have lasting true belief,
then even if one cannot have knowledge, one can have something just as valuable.
