Skepticism

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

In this paper, I consider Sterba’s recent criticism of skeptical theism in context of his argument from evil. I show that Sterba’s criticism of skeptical theism shares an undesirable trait with all past criticisms of skeptical theism: it fails. This is largely due to his focus on causal connections and his neglect of logical connections. Because of this, his argument remains vulnerable to skeptical theism.

The main question of metasemantics, or foundational semantics, is why an expression token has the meaning (semantic value) that it in fact has. In his reading of Ludwig Wittgenstein’s later work, Saul Kripke presented a skeptical challenge that threatened to make the foundational question unanswerable. My first contention in this paper is that the skeptical challenge indeed poses an insoluble paradox, but only for a certain kind of metasemantic theory, against which the challenge effectively works as a reductio ad absurdum (...) argument. My second contention is that as a result of rejecting the theory which entails a paradoxical outcome, we will see that the foundational question essentially involves a temporal dimension. After arguing that the skeptical challenge gives us a strong reason to adopt a historical view of meaning, I shall further argue against certain authors who claim that meanings not only have histories but futures as well, or that the meaning of a word may change retroactively in time as a consequence of counterfactual change in its future use. The major aim of the paper is thus to bring together the arguably interrelated debates about the skeptical challenge and temporal externalism in philosophy of language. (shrink)

G.E. Schulze's Aenesidemus, despite its importance for the development of post-Kantian idealism, has not been fully translated into English. Now and then, when I have time, I will upload draft translations of parts of the text here, with the goal of, at some point, providing a complete translation. These drafts will be rough and I welcome feedback! -/- This document contains only the Title page, Schulze's indication of the contents of the work, and the preface.

This dissertation is concerned with two of the largest questions that we can ask about the nature of physical reality: first, whether physical reality begin to exist and, second, what criteria would physical reality have to fulfill in order to have had a beginning? Philosophers of religion and theologians have previously addressed whether physical reality began to exist in the context of defending the Kal{\'a}m Cosmological Argument (KCA) for theism, that is, (P1) everything that begins to exist has a cause (...) for its beginning to exist, (P2) physical reality began to exist, and, therefore, (C) physical reality has a cause for its beginning to exist. While the KCA has traditionally been used to argue for God's existence, the KCA does not mention God, has been rejected by historically significant Christian theologians such as Thomas Aquinas, and raises perennial philosophical questions -- about the nature and history of physical reality, the nature of time, the nature of causation, and so on -- that should be of interest to all philosophers and, perhaps, all humans. While I am not a religious person, I am interested in the questions raised by the KCA. In this dissertation, I articulate three necessary conditions that physical reality would need to fulfill in order to have had a beginning and argue that, given the current state of philosophical and scientific inquiry, we cannot determine whether physical reality began to exist. -/- Friends of the KCA have sought to defend their view that physical reality began to exist in two distinct ways. As I discuss in chapter 2, the first way in which friends of the KCA have sought to defend their view that physical reality began to exist involves a family of a priori arguments meant to show that, as a matter of metaphysical necessity, the past must be finite. If the past is necessarily finite, then the past history of physical reality is necessarily finite. And if having a finite past suffices for having a beginning, then, since the past history of physical reality is necessarily finite, physical reality necessarily began to exist. I show that the arguments which have been offered thus far for the view that the past is necessarily finite do not succeed. Moreover, as I elaborate on in chapter 5, having a finite past does not suffice for having a beginning. -/- As I discuss in chapter 3, the second way in which friends of the KCA have sought to defend their view that physical reality began to exist involves a family of a posteriori arguments meant to show that we have empirical evidence that physical reality has a finite past history. For example, the big bang is sometimes claimed to have been the beginning of physical reality and, since we have excellent empirical evidence for the big bang, we have excellent empirical evidence for the beginning of physical reality. The big bang can be understood in two ways. On the one hand, the big bang can be understood as a theory about the history and development of the observable universe. Understood in that sense, then I agree that the big bang is supported by excellent empirical evidence and by a scientific consensus. On the other hand, some authors (particularly science popularizers, science journalists, and religious apologists) have wrongly interpreted big bang theory as a theory about the beginning of the whole of physical reality. As I argue, while a beginning of physical reality may be consistent with classical big bang theory, classical big bang theory does not provide good reason for thinking that physical reality began to exist. -/- In part II, I turn to discussing three necessary, but not necessarily sufficient, conditions for physical reality to have a beginning. Before discussing the three conditions, in chapter 4, I introduce three metaphysical accounts of the nature of time (A-theory, B-theory, and C-theory) as well as some formal machinery that will subsequently become useful in the dissertation. I introduce the first of the three conditions in chapter 5. According to the Modal Condition, physical reality began to exist only if, at the closest possible worlds without time, physical reality does not exist. I show that this condition helps us to make sense of various views in both theology and philosophy of physics. In chapter 6}, I introduce the second of my three conditions, the Direction Condition, according to which, roughly, physical reality began to exist only if all space-time points agree about the direction of time, so that all space-time points can agree that physical reality's putative beginning took place in their objective past. In chapter 7, I discuss the third condition, the Boundary Condition, according to which physical reality began to exist only if there is a past temporal boundary such that physical reality did not exist before the boundary. I show that there are two senses in which physical reality could be said to have had a past temporal boundary. Lastly, in chapter 8, I show that there is a relationship between my three conditions and classical big bang theory, even though the relationship is not the one usually identified in the literature. -/- In part III, I present four arguments for the view that, at the present stage of philosophical and scientific inquiry, we cannot know whether physical reality satisfies the three necessary conditions to have had a beginning and, consequently, we cannot know whether physical reality had a beginning. As I will prove in chapter 9, no set of observations that we currently have, when conjoined with General Relativity, entails that physical reality satisfies the Direction or Boundary Conditions. As I show in chapter 10, considerations in the philosophical foundations of statistical mechanics entail either that the Cosmos violates the Modal Condition or else that there is a transcendental condition on the possibility of our knowledge of the past that prevents our access to data we would need to gather to determine whether physical reality satisfies the Boundary Condition. In chapter 11, I show that there are a number of live cosmological models according to which physical reality does not satisfy the Boundary Condition. As long as we don't know whether any of those cosmological models are correct, we do not know whether physical reality satisfies the Boundary Condition. Lastly, I turn to confirmation theory and show that, at our present stage of inquiry, ampliative inferences for the conclusion that physical reality satisfies the Modal, Direction, and Boundary Conditions are not successful.

It is not uncommon in the history of science and philosophy to encounter crucial experiments or crucial objections the truth-value of which we are ignorant, that is, about which we suspend judgment. Should we ignore such objections? Contrary to widespread practice, I show that in and only in some circumstances they should not be ignored, for the epistemically rational doxastic attitude is to suspend judgment also about the hypothesis that the objection targets. In other words, suspension of judgment "propagates" from (...) the crucial objection to the hypothesis. In this paper I study under which conditions this phenomenon occurs, and discuss its significance for the topics of skepticism and scientific realism. (shrink)

There is a large literature exploring how accuracy constrains rational degrees of belief. This paper turns to the unexplored question of how accuracy constrains knowledge. We begin by introducing a simple hypothesis: increases in the accuracy of an agent’s evidence never lead to decreases in what the agent knows. We explore various precise formulations of this principle, consider arguments in its favor, and explain how it interacts with different conceptions of evidence and accuracy. As we show, the principle has some (...) noteworthy consequences for the wider theory of knowledge. First, it implies that an agent cannot be justified in believing a set of mutually inconsistent claims. Second, it implies the existence of a kind of epistemic blindspot: it is not possible to know that one’s evidence is misleading. (shrink)

Given the multiple crises that are occurring after decades of neoliberalism we should take care to examine neoliberalism’s claims and subject them to critical scrutiny. What I propose to do here is to examine some of the philosophical claims made by Friedrich Hayek and then submit them to scrutiny using tools from Hayek’s cousin, Ludwig Wittgenstein.

I discuss three understandings of the idea of “Knowledge First Epistemology”, i.e. Timothy Williamson’s suggestion that we should take knowledge as a starting point, rather than trying to analyze it. Some have taken this to be a suggestion about the role of the concept of knowledge, but Williamson also seems to be concerned with intuition-based metaphysics. As an alternative, I develop the idea that knowledge may be a social kind that can be understood through a functional analysis in the tradition (...) of Edward Craig. (shrink)

To resolve the lottery paradox, the “no-justification account” proposes that one is not justified in believing that one's lottery ticket is a loser. The no-justification account commits to what I call “the Harman-style skepticism”. In reply, proponents of the no-justification account typically downplay the Harman-style skepticism. In this paper, I argue that the no-justification reply to the Harman-style skepticism is untenable. Moreover, I argue that the no-justification account is epistemically ad hoc. My arguments are based on a rather surprising finding (...) that the no-justification account implies that people living in Taiwan typically suffer from the Harman-style skepticism. (shrink)

The deduction of categories in the 1781 edition of the Critique of the Pure Reason (A Deduction) has “two sides”—the “objective deduction” and the “subjective deduction”. Kant seems ambivalent about the latter deduction. I treat it as a significant episode of Kant’s thinking about categories that extended from the early 1770s to around 1790. It contains his most detailed answer to the question about the origin of categories that he formulated in the 1772 letter to Marcus Herz. The answer is (...) that categories are generated a priori through a kind of intellectual “epigenesis”. This account leaves unexplained why precisely such and such categories should be generated. While this observation caused Kant to worry about the hypothetical status of the subjective deduction in 1781, he would come to acquiesce in the recognition that the ground of the possibility of categories is itself inscrutable. I call this his “methodological skepticism”. (shrink)

In her book Michel de Montaigne: Accidental Philosopher, Ann Hartle argues that Montaigne’s thought is dialectical in the Hegelian sense. Unlike Hegel’s progressive dialectic, however, Montaigne’s thought is, according to Hartle, circular in that the reconciliation of opposed terms comes not in the form of a newly emergent term, but in a return to the first term, where the meaning of the first is transformed as a result of its dialectical interaction with the second. This analysis motivates Hartle’s claim that (...) Montaigne is not a skeptic at all, let alone a Pyrrhonian skeptic. In this paper, I argue that Hartle’s circular-dialectical interpretation of Montaigne is not only compatible with Pyrrhonism, but is in fact an ideal model for understanding Sextus Empiricus’s skeptical therapy.

William L. Rowe cites Stephen Wykstra's skeptical theism as the most powerful objection to the evidential argument. Initially, I object to skeptical theism on the basis that skeptical theism leads to moral paralysis. I then will conclude that the skeptical theist has other resources that enable the formation of a moral code.

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.

“I know that p but it is possible that not-p” sounds contradictory. Some philosophers, notably David Lewis, have taken this as evidence that knowledge requires infallibility. Others have attempted to undermine that inference by arguing that there is a plausible pragmatic explanation of why such sentences sound odd, and thus do not undermine fallibilism. I argue that the proffered pragmatic explanations fail and I raise challenges for any possible pragmatic explanation of the character of concessive knowledge attributions. It is reasonable (...) to conclude that concessive knowledge attributions are genuine contradictions. (shrink)

In many tragic plays, the protagonist is brought down by a disaster that is a consequence of the protagonist's own error, his or her hamartia, the tragic flaw. Tragic flaws are disconcerting to the audience because they are not known or fully recognized by the protagonist—at least not until it is too late. In this essay, I take tragic flaws to be unreliable belief-forming dispositions that are unrecognized by us in some sense. I describe some different types of flaws and (...) consider what we might do about them. Then I examine three types of policies for managing our tragic flaws: doxastic, dispositional, and methodological. (shrink)

Skepticism about blameworthiness says that there is good reason to doubt that, in our world, humans are ever blameworthy for their deeds. A significant problem for the discussion of this view is that it is unclear how to understand the kind of blame that should be at issue. This paper makes a new proposal. The basic idea is that the kind of blame skeptics should be skeptical about is constituted by responses that can violate the targets’ claims and by the (...) responders’ thought that the targets have forfeited this claim because of their morally objectionable actions and because of how they were when they performed them. This view identifies an important part of our everyday lives and frames discussions about skepticism about blameworthiness in a new way. (shrink)

Since at least 2016, many have worried that social media enables authoritarians to meddle in democratic politics. The concern is that trolls and bots amplify deceptive content. In this chapter I argue that these tactics have a more insidious anti-democratic purpose. Lies implanted in democratic discourse by authoritarians are often intended to be caught. Their primary goal is not to successfully deceive, but rather to undermine the democratic value of testimony. In well-functioning democracies, our mutual reliance on testimony also generates (...) a distinctively democratic value: decentralized testimonial networks evade control by the state or powerful actors. The deliberate exposure of deception in democratic testimonial networks undermines this value by implicating citizens in their own epistemic corruption, weakening the resilience of democratic society against authoritarian pressure. In this chapter I illustrate that danger through a close reading of recent Russian social media interference operations, showing both their epistemic underpinnings and their ongoing political threat.

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 chapter offers non-retributive, broadly Kantian justifications of punishment and remorse which can be endorsed by free will skeptics. We lose our grip on some Kantian ideas if we become skeptical about free will, but we can preserve some important ones which can do valuable work for free will skeptics. The justification of punishment presented here has consequentialist features but is deontologically constrained by our duty to avoid using others as mere means. It draws on a modified Rawlsian original position (...) in which we assume we are just as likely to be among the punished when the veil of ignorance is raised as we are to be among those protected by the institution of punishment. The justification of remorse presented here is care-based, and draws on the value of sympathizing with people we have wronged, which has a Kantian ground in the duty to take others’ ends as our own.

Epistemological disjunctivism (ED) has been thought to solve the conditionality problem for epistemic externalism. This problem arises from externalists’ characterization of our epistemic standings as conditional on the obtaining of worldly facts which we lack any reflective access to. ED is meant to avoid the conditionality problem by explicating subjects’ perceptual knowledge in paradigmatic cases of perceptual knowledge via their possession of perceptual reasons that are both factive and reflectively accessible. I argue that ED’s account of reflectively accessible factive perceptual (...) reasons is also prey to the conditionality problem. After that, I submit that Stroud’s influential formulation of the conditionality problem relies on a methodological requirement that is potentially dissociable from ED. So, it is possible to put ED in the service of a more modest anti-skeptical strategy. I close by suggesting that this modest anti-skeptical strategy successfully undercuts the underdetermination-based skeptical paradox. Nevertheless, it does not have substantial advantages over some forms of epistemic externalism. (shrink)

Skeptical theists are seeking for some reasonable solutions to the evidential problem of evil. One of the most fundamental responses of skeptical theism is that the concept of “gratuitous evil”, which cannot be a proof of the absence of God. Therefore, it is not the existence of God that skeptical theism suspects. Instead, skeptical theism contemplates whether the evil in the world really has a “gratuitous” basis. This paper focuses on Peter van Inwagen's “no-minimum claim”. No-minimum claim” stands in opposition (...) to the views that assume that God minimizes the evils that exist in the world in order to achieve justice. “No-minimum claim” acknowledges that these evils still have enormous amounts to people. Thus “no-minimum claim” suggests that the evils experienced in the world are incompatible with the “best of all possible worlds” views or the other explanations of classical theodicy. According to the “no minimum claim”, the reason why the amount of evil in the world still seems so high may be God’s deliberate calculations in effecting the distribution of these evils. In order to reach these calculations, it is not necessary for the amount of evil that God allowed to reflect on the world to be perfectly manifested at the minimum level. The purpose of this paper is to consider the skeptical theism approach within the framework of Peter van Inwagen's “no-minimum claim” and to limit his arguments to an alternative approach to skeptic theism. Our claim is that such view coincides with skeptical theism, but the “no- minimum claim” still has some ambiguities at the point of the limits of evil. From this, we can conclude that the “no minimum claim” has received many objections in the skeptical theism literature and these objections are justified at certain points. (shrink)

This is a technical treatise for the scientific-minded readers trying to expand their intellectual horizon beyond the straitjacket of materialism. It is dedicated to those scientists and philosophers who feel there is something more, but struggle with connecting the dots into a more coherent picture supported by a way of seeing that allows us to overcome the present paradigm and yet maintains a scientific and conceptual rigor, without falling into oversimplifications. Most of the topics discussed are unknown even to neuroscientists, (...) biologists, philosophers, and yet are based on the findings published in their own mainstream peer reviewed literature or on deep insights of the scientific, philosophical and spiritual giants of the past. A scientific, philosophical, and spiritual overview of the relationship between science and spirituality, neuroscience and the mystery of consciousness, mind and the nature of reality, evolution and life. A plaidoyer for a science that goes beyond the curve of reason and embraces a new synthesis of knowledge. The overcoming of the limitations of the intellect into an extended vision of ourselves and Nature. A critique of physicalism, the still-dominant doctrine that believes that all reality can be reduced to matter and the laws of physics alone. A review and reassessment of the old and new philosophical and metaphysical ideas which attempts to bring closer Western and Eastern traditions where science, philosophy, consciousness, Spirit and Nature are united in a grand vision that transcends the limited conventional scientific and philosophical paradigm. A possible answer to the questions of purpose and meaning and the future evolution of humankind beyond a conception that posits a priori a purposeless and meaningless universe. A report of the new scientific discoveries of a basal intelligence in cells and plants, on the question if mind is computational, the issue of free will, the mind-body problem, and the so called ‘hard problem of consciousness’. An essay on ancient as modern philosophical conceptions, from the One of Plotinus, the God of Spinoza until the recent revival of panpsychism or the universal consciousness. A journey into quantum physics from the perspective of philosophical idealism and an invitation to adopt new ways of seeing that might help us to transform our present understanding, expanding it into an integral cosmology, with a special emphasis on the spiritual and evolutionary cosmology of the Indian seer Sri Aurobindo. Not just a philosophical and metaphysical meditation but, rather, an appeal to work towards a change of consciousness, a widening of our perspective towards a new way of seeing beyond a purely mechanistic worldview to avoid a social, environmental and economic collapse. Humans are transitional beings that will have to make a choice: relapse into a pre-rational state or evolve towards a new trans-rational species supported by an ideal of human unity in diversity as the expression of a spiritual evolutionary process, the call of the Spirit on Nature.

Knowledge is central to epistemology. Indeed, the word ‘epistemology’ comes from the Greek word epistêmê, which is often translated as ‘knowledge.’ But what is knowledge? Why do we value it? How is it acquired? And how much of it do we have? This article explores the nature, significance, sources, and extent of human knowledge.

This paper analyzes the way in which skepticism led to the crisis of the criteria of truth and action that developed in Stoic philosophy. The attempts of the skeptics to escape the difficulties caused by their radical philosophical views are presented. Special attention was paid to the importance that yielding to the customs and traditions of the community in which they lived had in the life of skeptics deprived of these criteria. This approach to action and problem solving in general (...) has a special significance and value in times of crisis, and it is often easy to overlook. (shrink)

This dissertation examines the relationship of skepticism and philosophy in the work of G.W.F. Hegel. Whereas other commentators have come to recognize the epistemological significance of Hegel's encounter with skepticism, emphasizing the strength of his system against skeptical challenges to the possibility of knowledge, I argue that Hegel develops his metaphysics in part through his ongoing engagement with the skeptical tradition. As such, I argue that Hegel's interest is not in refuting skepticism, but in defining its legitimate role within the (...) project of philosophical science. Hegel finds that historical forms of skepticism have misunderstood their own activity and thus have drawn the wrong conclusions from the epistemological challenges that they raise. For Hegel, these challenges lead not to the suspension of judgment, as many skeptics have assumed, but to an insight into the fundamental nature of reality itself. For this reason, I argue that it is important to distinguish between historical forms of skepticism (e.g., Pyrrhonism) and the "self-completing skepticism" that Hegel describes in the Phenomenology of Spirit. It is the latter sense of skepticism, I argue, that one finds at work in Hegel's own philosophical project at nearly every stage of his career. (shrink)

Faced with current urgent calls for more trust in experts, especially in high impact and politically sensitive domains, such as climate science and COVID-19, the complex and problematic nature of public trust in experts and the need for a more critical approach to the topic are easy to overlook. Scepticism – at least in its Humean mitigated form that encourages independent, questioning attitudes – can prove valuable to democratic governance, but stands in opposition to the cognitive dependency entailed by epistemic (...) trust. In this paper, we investigate the tension between the value of mitigated scepticism – understood as the exercise of reason-based doubt in a particular domain – and the need for trust in experts. We offer four arguments in favour of mitigated scepticism: the argument from loss of intellectual autonomy; the argument from democratic deficit; the argument from the normative failures of science; and the argument from past and current injustices. These arguments highlight the tension between the requirements for trust and justified scepticism about the role of experts. One solution, which we reject, is the idea that reliance, rather than trust, is sufficient for the purposes of accommodating experts in policy matters. The solution we endorse is to create a ‘climate of trust’, where questioning experts and expertise is welcomed, but the epistemic trust necessary for action upon information which the public cannot obtain first-hand is enabled and encouraged through structural, institutional, and justice-based measures.

U ovom radu analizira se rešenje skeptičkog paradoksa koje pruža teorija relevantnih alternativa. Ispituju se i upoređuju dve verzije ovog rešenja: nekontekstualistič- ka čiji je tvorac i zastupnik Fred Drecke, i kontekstualistička koju zastupaju autori poput Kita Dirouza i Stjuarta Koena. Uporednom analizom nekontekstualističkog i kontekstuali- stičkog rešenja, dolazi se do zaključka da, iako oba rešenja imaju i povoljne i nepovoljne implikacije, Dreckeova teorija relevantnih alternativa nudi uverljivije objašnjenje, a zatim i rešenje skeptičkog paradoksa.

The focus of this chapter will be Kant’s understanding of Hume, and its impact on Kant’s critical philosophy. Contrary to the traditional reading of this relationship, which focuses on Kant’s (admittedly real) dissatisfaction with Hume’s account of causation, my discussion will focus on broader issues of philosophical methodology. Following a number of recent interpreters, I will argue that Kant sees Hume as raising, in a particularly forceful fashion, a ‘demarcation challenge’ concerning how to distinguish the legitimate use of reason in (...) (say) natural scientific contexts from the illegitimate use of it in (say) dogmatic metaphysics. I will then go on to argue that Kant sees Hume’s tendency to slide into more radical forms of skepticism as a symptom of his failure to provide a systematic or principled account of this distinction. This failure, I argue, can be traced (according to Kant) to Hume’s impoverished, non-hylomorphic account of our faculties – which both robs Hume of the materials necessary to construct a genuinely systematic philosophy as Kant understands this, and makes it impossible for Hume to clearly conceive of what Kant calls ‘Formal Idealism.’ In this way, the failings of Hume’s account of causation are (for Kant) symptoms of more fundamental limitations within Hume’s philosophy. I close by briefly discussing the similarities between Hume and Kant’s understanding of the relationship between, first, philosophical methodology and, second, the nature of our faculties. (shrink)

Thompson Clarke’s seminal paper “The Legacy of Skepticism” (1972) is notoriously difficult in both substance and presentation. Despite the paper’s importance to skepticism studies in the nearly half-century since its publication, no attempt has been made in the secondary literature to provide an account, based on a close reading of the text, of just what Clarke’s argument is. Furthermore, much of the existing literature betrays (or so it seems to me) fundamental misunderstandings of Clarke’s thought. In this essay, I attempt (...) to explain—concisely but comprehensively—Clarke’s overall argument in “The Legacy of Skepticism.”. (shrink)

In this paper, we develop a novel response to counterfactual scepticism, the thesis that most ordinary counterfactual claims are false. In the process we aim to shed light on the relationship between debates in the philosophy of science and debates concerning the semantics and pragmatics of counterfactuals. We argue that science is concerned with many domains of inquiry, each with its own characteristic entities and regularities; moreover, statements of scientific law often include an implicit ceteris paribus clause that restricts the (...) scope of the associated regularity to circumstances that are ‘fitting’ to the domain in question. This observation reveals a way of responding to scepticism while, at the same time, doing justice both to the role of counterfactuals in science and to the complexities inherent in ordinary counterfactual discourse and reasoning.

This chapter reviews several varieties of grounding skepticism as well as responses that have been proposed by grounding enthusiasts to considerations raised by grounding skeptics. Grounding skeptics, as I conceive of them here, are theorists who belong to one of the following two schools of thought. “Old-school” grounding skeptics doubt the theoretical utility of the grounding idiom by denying one of its presuppositions, viz., that this notion is at least intelligible or coherent. “Second-generation” grounding skeptics call into question the theoretical (...) utility of the grounding idiom for other reasons; their skeptical doubts tend to focus on one of the following three purported theoretical virtues grounding enthusiasts ascribe to their idiom: (i) its alleged power to unify an apparently heterogeneous collection of phenomena; (ii) its alleged power to capture and/or elucidate the distinction between the fundamental and the non-fundamental; or (iii) the alleged metaphysical (as opposed to mind-dependent, epistemic, or psychological) utility of grounding claims. Grounding enthusiasts have already formulated responses to many of the objections described in this chapter. At this point, however, it is fair to say that the state of the literature is still evolving, and no conclusive judgment can therefore be reached as of yet as to whether grounding enthusiasts or grounding skeptics have gained the upper hand in these debates. In the meantime, though, grounding skeptics continue to maintain that the classification of factual and/or nonfactual connections under the rubric of grounding does not really help us illuminate the nature of the connections at issue; instead, from the view of the grounding skeptic, we are better off studying these various connections separately and in their own right.

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 discuss full-blooded Platonism (the claim that all possible mathematical objects exist) as a response to the skeptical problem in the philosophy of mathematics as to how empirical beings can cognize non-empirical mathematical objects. I then attempt to develop an analogous position regarding the applicability of concepts to reality in response to the skeptical problem regarding how we can cognize an objective reality through human-constructed concepts. If all concepts meeting certain minimal conditions structure reality under some aspect, (...) then objective knowledge is possible, regardless of how these concepts arose historically. (shrink)

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)

We know very little about mathematical skepticism in modem times. Imre Lakatos once remarked that “in discussing modem efforts to establish foundations for mathematical knowledge one tends to forget that these are but a chapter in the great effort to overcome skepticism by establishing foundations for knowledge in general." And in a sense he was clearly right: modem thought — with its new discoveries in mathematical sciences, the mathematization of physics, the spreading of Pyrrhonist doctrines, the centrality of epistemological foundationalism (...) and the diffusion of the geometrical method in philosophy — was the most natural arena in which skepticism and mathematics could confront each other. The problem remains, however, that no investigation of the whole topic has yet been attempted. Thus, as far as we know, mathematical certainties should have clashed with skeptical doubts, but whether and to what extent there was indeed a historical debate on mathematical skepticism in modern thought remains to be ascertained.

The subject of this book came up in several different places and dates, scattered in my experience in the countless times I was asked to think, discuss or pronounce myself on the idea that we have (or should have) an ability to judge that is part of our human nature, that we have the power to weigh our own opinions and, with this, conduct our lives and carry out the valuable tasks of properly knowing the world and properly deciding what (...) to do. The fact is that at a certain moment, between readings, conferences, and the anomalies of everyday life, a question occurred to me about the possibility and value of reflection - understood as the act of examining one's own mental states.

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

This paper focuses on what Peirce means by scepticism, with particular reference to the anticartesian nature of his philosophy and the question of whether Peirce constantly shows a univocal and consistent attitude towards all types of scepticism. It argues that Peirce can be described as an antisceptic, and then goes on to discuss the extent to which Peirce’s fallibilism can claim to succeed in entirely divorcing itself from a sceptical outlook. -/- .

This publication is a review of RIchard H. Popkin's Scepticism in the History of Philosophy.

Formal models of appearance and reality have proved fruitful for investigating structural properties of perceptual knowledge. This paper applies the same approach to epistemic justification. Our central goal is to give a simple account of The Preface, in which justified belief fails to agglomerate. Following recent work by a number of authors, we understand knowledge in terms of normality. An agent knows p iff p is true throughout all relevant normal worlds. To model The Preface, we appeal to the normality (...) of error. Sometimes, it is more normal for reality and appearance to diverge than to match. We show that this simple idea has dramatic consequences for the theory of knowledge and justification. Among other things, we argue that a proper treatment of The Preface requires a departure from the internalist idea that epistemic justification supervenes on the appearances and the widespread idea that one knows most when free from error.

In her book Extended Rationality: A Hinge Epistemology (2015), Annalisa Coliva puts forward an anti-sceptical proposal based on the idea that the notion of rationality extends to the unwarrantable presuppositions “that make the acquisition of perceptual warrants possible” (2015: 150). These presuppositions are commonly the target of sceptical arguments, and by showing that they are on the one hand unwarrantable, but on the other are constitutive components of rationality itself, she reveals that they are beyond rational doubt and thus avoids (...) scepticism. Part of Coliva’s defence of using extended rationality in this way involves distancing it from relativist interpretations, which she describes as “devastating” (2015: 120). She proposes two ways that someone might attempt to formulate epistemic relativism from her extended rationality view, and argues that both would be unsuccessful because they require describing alternative conceptions of rationality which are “unintelligible” (in the first case), or “inconceivable” (in the second). The superficial claim of this chapter is that Coliva’s arguments, as they stand, are insufficient to dismiss relativism. She fails to show that the conception of rationality needed for the first formulation of relativism is unintelligible, and overestimates the significance of the second formulation’s conception turning out to be inconceivable. But I also highlight a deeper problem: neither formulation follows a realistic blueprint for relativism, and so these were the wrong possibilities to consider in the first place. To address this issue, I propose a third, more plausible, way in which someone might attempt to formulate relativism on the basis of Coliva’s account. I leave open whether this strategy is successful, or whether a version of Coliva’s criticisms apply to it too. (shrink)
