Hume’s sceptical attack on the rational theology of his days is closely interwoven with his attempt to develop a wholly naturalistic account of morality. Hume thus explores the possibility to develop an ethics devoid of any reliance on traditional faith or any type of theistic-providential metaphysics. In this article the consequences of this position are examincd. First, two major versions of a theistic-providential underpinning of morality in the tradition of 18th-century British moral philosophy, notably those from Samuel Clarke and Francis (...) Hutcheson, are examined. In the following, a reconstruction is made of Hume’s sceptical attack on the rational theology of his days . In a third move, the consequences of Hume’ s religious scepticism for the positive articulation of his ethical theory are pointed out. In the conclusion it becomes apparent that Hume’s religious scepticism remains strongly influenced by the classical idea of an intrinsic relation between contemplation and moral wisdom: but the contemplative wisdom of Hume’s ‘true religion’ is of a radical anti-teleological kind and implies indeed a breach with the Christian inspired moral metaphysics of his days.

This book, which originated as the author's 2013 Oxford dissertation, treats five modes of argument described by the Pyrrhonian skeptic Sextus Empiricus. In the first book of the Outlines of Pyrrhonism, Sextus claims that these modes bring about suspension of judgment, a mental state in which one finds the considerations for and against some claim to be balanced. We see the modes used both alone and in combination when Sextus investigates dogmatic philosophy. Accordingly, Sienkiewicz assigns a chapter to each mode (...) and concludes with how they might work together. This book has much to commend it: Sextus's text is clearly explained... (shrink)

Arguments for scepticism about perceptual knowledge are often said to have intuitively plausible premises. In this discussion I question this view in relation to an argument from ignorance and argue that the supposed persuasiveness of the argument depends on debatable background assumptions about knowledge or justification. A reasonable response to scepticism has to show there is a plausible epistemological perspective that can make sense of our having perceptual knowledge. I present such a perspective. In order give a more (...) satisfying response to scepticism, we need also to consider the standing of background beliefs. This is required since the recognitional abilities that enable us to have perceptual knowledge are informed by, or presuppose, a picture or conception of the world the correctness of which we have not ascertained. The question is how, in the face of this, to make sense of responsible belief-formation. In addressing this problem I make a suggestion about the standing of certain crucial beliefs linking appearances with membership of kinds. (shrink)

This paper offers a detailed criticism of different versions of modal scepticism proposed by Van Inwagen and Hawke, and, against these views, attempts to vindicate our reliance on thought experiments in philosophy. More than one different meaning of “ modal scepticism” will be distinguished. Focusing mainly on Hawke’s more detailed view I argue that none of these versions of modal scepticism is compelling, since sceptical conclusions depend on an untenable and, perhaps, incoherent modal epistemology. With a detailed (...) account of modal defeaters at hand I argue that Van Inwagen and Hawke’s scepticism is either groundless, or it leads to boundless and unacceptable modal scepticism. Additionally, I show that Hawke’s conception of analogical modal reasoning is problematic. Either his principle of similarity is arbitrary or it begs the question about modal scepticism. In contrast to Hawke’s restricted view of analogical modal reasoning, I present two examples of analogy-based modal justification of philosophically relevant possibility claims. My criticism of modal scepticism also shows that there is no good reason to insist on a sharp distinction between an unproblematic and a presumably dubious kind of modality. The upshot is that in absence of proper defeaters both Yablo-style conceivability and properly applied analogical reasoning are reliable guides to possibility, and also that modal justification comes in degrees. The proposed framework of defeaters of modal justification as well as the analysed examples of analogical modal reasoning trace out interesting new areas for further discussions. (shrink)

Saul_Jennifer, Scepticism and Implicit Bias.

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative (...) ought judgments bring with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)

Scepticism does not argue that no one knows to avoid self-referential refutation. It falls back to arguing that no one knows that anyone knows, hence simply that no one knows, in accordance with the principle Kp iff KKp. This principle, however, is not available to the sceptic. He is stuck with -KKp without access to -Kp. The sceptic is thus no threat to the sort of knowledge that like Moore we all claim to have.

Scepticism is central to Nietzsche’s philosophical project, both as a tool of criticism and, through its role in self-transformation, as a tool for responding to criticism. While its importance in his thought and its complexity have been acknowledged, exactly what kind of scepticism Nietzsche calls for still stands in need of analysis. Jessica Berry’s [Nietzsche and the Ancient Skeptical Tradition. New York: Oxford University Press, 2011] comparison between Nietzsche and Pyrrhonian scepticism recognized the importance of the practical (...) dimension of Nietzschean scepticism but distorted Nietzsche’s philosophy in attempting to paint it as Pyrrhonian in character. Earlier discussions recognize Nietzsche’s opposition to Pyrrhonian suspension of judgement and tranquillity. They have not, however, explored in sufficient detail Nietzsche’s sceptical practice and how it affects the individual. In this article, I combine Berry’s emphasis on scepticism as a practice with attention to the important differences between Nietzsche and Pyrrhonism. I outline Nietzsche’s scepticism as a transformative practice, arguing that its differences from Pyrrhonian scepticism are as illuminating as any similarities. The scepticism that Nietzsche advocates involves not just destruction of our beliefs but destruction of who we are, and at the same time as cultivating the capacity to do without certainty, requires an experimental engagement with our drives – allowing the creation of new values.

Exegetical scepticism is a strand of scepticism about meaning running through the German Enlightenment. This paper provides the first modern account of its tenets, critics, and proponents, and argues that it shares essential features with modern varieties of meaning-scepticism that have been a preoccupation among philosophers of language since the middle of the twentieth century. I argue that exegetical scepticism is a type of epistemological scepticism first introduced as a philosophical position in a theological debate (...) between August Pfeiffer (1640–1698) and Philipp Jacob Spener (1635–1705). Under contention, so I argue, was the idea that interpretation is never certain because it is necessarily underdetermined by the evidence. Following the effects of this controversy, I show that exegetical scepticism caused a great deal of unrest in German letters in the eighteenth century and can be seen to contribute to the great proliferation of hermeneutical theories in the Aufklärung, indeed to the very birth of hermeneutics as a standalone discipline. Bringing this type of scepticism to contemporary attention supports a reassessment of issues at the heart of meaning-scepticism and hermeneutics itself, and a reconsideration of the histories of Enlightenment scepticism and hermeneutics.

I have argued for a kind of ‘counterfactual scepticism’: most counterfactuals ever uttered or thought in human history are false. I briefly rehearse my main arguments. Yet common sense recoils. Ordinary speakers judge most counterfactuals that they utter and think to be true. A common defence of such judgments regards counterfactuals as context-dependent: the proposition expressed by a given counterfactual can vary according to the context in which it is uttered. In normal contexts, the counterfactuals that we utter are (...) typically true, the defence insists, while granting that there may be more rarefied contexts in which they are false. I give a taxonomy of such contextualist replies. One could be a contextualist about the counterfactual connective, about its antecedent, or about its consequent. I offer some general concerns about all these varieties of contextualism. I then focus especially on antecedent-contextualism, as I call it. I firstly raise some high-level objections to it. Then, I look at such a contextualist account due to Sandgren and Steele. I think it has many virtues, but also some problems. I conclude with some avenues for future research. (shrink)

PYRRHONIAN SCEPTICISM, as presented in the writings of Sextus Empiricus, differs in various ways from the forms of scepticism that continue to be of such central concern to modern philosophers. Two differences stand out immediately. One is Pyrrhonism's practical orientation. For Sextus, scepticism is a way of life in which suspension of judgment leads to the peace of mind the sceptic identifies with happiness. The other is the puzzling failure on the part of the Pyrrhonists, along with (...) all other ancient sceptics, to formulate the sceptical problem that many modern and contemporary philosophers regard as fundamental and paradigmatic: the problem of our knowledge of the external world.

The relation of scepticism to infallibilism and fallibilism is a contested issue. In this paper I argue that Cartesian sceptical arguments, i.e. sceptical arguments resting on sceptical scenarios, are neither tied to infallibilism nor collapse into fallibilism. I interpret the distinction between scepticism and fallibilism as a scope distinction. According to fallibilism, each belief could be false, but according to scepticism all beliefs could be false at the same time. However, to put this distinction to work sceptical (...) scenarios have to be understood as ignorance-possibilities, not as error-possibilities. To show that scepticism is not tied to infallibilism I reject the principle of unrestricted relevance according to which any error- or ignorance-possibility whatsoever is relevant. Instead I argue that the sceptic should distinguish between local and global ignorance-possibilities. Global ignorance-possibilities are relevant even though not all ignorance-possibilities are relevant. The result is a refined version of the Cartesian sceptical argument that avoids two traps other versions do not avoid. (shrink)

Radical scepticism contends that our knowledge of the external world is impossible. Particularly, radical scepticism can be motivated by the closure principle. Several commentators have noted that a straightforward way to respond to such arguments is via externalist strategies, e.g., Goldman, Greco, Bergmann. However, these externalist strategies are not effective against a slightly weaker form of the argument, a closure principle for rationally grounded knowledge, closureRK.\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${closure}_{RK.}$$\end{document} The sceptical argument, framed (...) around the closureRK\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\hbox {closure}_{\mathrm{RK}}$$\end{document} principle, targets rationally grounded knowledge. Although externalist strategies are ineffective against this form of argument, its conclusion can nonetheless be resisted by combining, in a novel way, the resources of Wittgenstein and Davidson.

Alternatively, I argue for The Conditionality of Rational Support Thesis, i.e., the thesis that rational support via competent deduction is conditional. In particular, rational support must be provided within an evaluative system in which hinge propositions are presupposed and contentful beliefs are being evaluated. In the end, we can resist the closureRK\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\hbox {closure}_{\mathrm{RK }}$$\end{document}-based sceptical argument while retaining the closureRK\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\hbox {closure}_{\mathrm{RK}}$$\end{document} principle.

If it works, I can use Putnam’s vat argument to show that I have not always been a brain-in-a-vat. It is widely thought that the vat argument is of no use against closure scepticism – that is, scepticism motivated by arguments that appeal to a closure principle. This is because, even if I can use the vat argument to show that I have not always been a BIV, I cannot use it to show that I was not recently (...) envatted, and it is thought that the claim that I am not justified in thinking that I was not recently envatted is all that the closure sceptic requires. In this paper I first argue that scenarios in which I have been recently envatted are inadequate for the sceptic’s purposes, and so the standard argument that the vat argument is of no use against closure scepticism fails. I then argue that it is not possible to revise the standard argument to meet my objection. I conclude that, if it works, I can use the vat argument as a defence against closure scepticism. (shrink)

This chapter contains sections titled: Introduction Quine on Indeterminacy of Translation: The Argument from Below Quine on Indeterminacy of Translation: The Argument from Above Kripke's Wittgenstein's Attack on Meaning Conclusion.

Originally published in 1968. Scepticism is generally regarded as a position which, if correct, would be disastrous for our everyday and scientific beliefs. According to this view, a sceptical argument is one that leads to the intuitively false conclusion that we cannot know anything. But there is another, much neglected and more radical form of scepticism, Pyrrhonism, which neither denies nor accepts the possibility of knowledge and is to be regarded not as a philosophical position so much as (...) the expression of a philosophical way of life. Professor Naess argues that, given a sympathetic interpretation, Sextus Empiricus’s outline of Pyrrhonian scepticism provides the essentials of a genuine and rational sceptical point of view. He begins with a brief account of Pyrrhonism, then goes on to argue for the psychological possibility of this kind of scepticism, defending it against common objections, and examining some of its implications. The last two chapters provide detailed support for the rationality of Pyrrhonism, drawing mainly on certain methodological distinctions in semantics which both justify the Pyrrhonist’s failure to make assertions and restrict the scope of recent epistemological arguments against scepticism in such a way as to modify severely the conclusions based on them.

Scepticism, a philosophical tradition that casts doubt on our ability to gain knowledge of the world and suggests suspending judgment in the face of uncertainty, has been influential since its beginnings in ancient Greece. Harald Thorsrud provides an engaging, rigorous introduction to the central themes, arguments, and general concerns of ancient Scepticism, from its beginnings with Pyrrho of Elis to the writings of Sextus Empiricus in the second century A.D. Thorsrud explores the differences among Sceptics and examines in (...) particular the separation of the Scepticism of Pyrrho from its later form—Academic Scepticism—the result of its ideas being introduced into Plato's Academy in the third century B.C. Steering an even course through the many differences of scholarly opinion surrounding Scepticism, the book also provides a balanced appraisal of the philosophy's enduring significance by showing why it remains so interesting and how ancient interpretations differ from modern ones. _Copub: Acumen Publishing Limited _.

Scepticism is a subject which has preoccupied philosophers for two thousand years. This book presents an historical perspective on scepticism by considering contrasting views, such as those of Sextus Empiricus, Descartes and Hume, on why scepticism is important. With its historical perspective and analysis of contemporary discussions, _Scepticism_ provides a broad focus on the subject, differing from other discussions of the topic in the importance it attaches to scepticism both in Greek thought and in pre-twentieth century (...) views generally.

Viewing moral scepticism as the rejection of objective desirabilities, inductive scepticism may be seen as the rejection of objective believabilities. Moral scepticism leads naturally to amoralism rather than subjectivism, and inductive scepticism undermines not our practices of induction but only a view about justification. The two scepticisms together amount to the adoption of a defensibly narrow, formal view of reason.

I focus on a key argument for global external world scepticism resting on the underdetermination thesis: the argument according to which we cannot know any proposition about our physical environment because sense evidence for it equally justifies some sceptical alternative (e.g. the Cartesian demon conjecture). I contend that the underdetermination argument can go through only if the controversial thesis that conceivability is per se a source of evidence for metaphysical possibility is true. I also suggest a reason to doubt (...) that conceivability is per se a source of evidence for metaphysical possibility, and thus to doubt the underdetermination argument. (shrink)

Scepticism in the Sixth Century? Damascius' Doubts and Solutions Concerning First Principles SARA RAPPE THE Doubts and Solutions Concerning First Principles, an aporetic work of the sixth century Neoplatonist Damascius, is distinguished above all by its dialectical subtlety. Although the Doubts and Solutions belongs to the commentary tradi- tion on Plato's Parmenides, its structure and method make it in many ways unique among such exegetical works. The treatise positions itself, at least in part, as a response to Proclus' metaphysical (...) system. Thus the first principles alluded to in its title refer to a metaphysical structure consisting of five central elements, the Ineffable, the One, and the Noetic Triad, which Damascius both adumbrates in opposition to Proclus' as well as subjects to his own, internal critique. In this article, I will be asking whether or not Damascius' critique of Neoplatonic metaphysics is informed or inspired by ancient Scepticism. No doubt this question catches the reader off guard: if the last exponent of an- cient Scepticism is Sextus Empiricus, how could this sixth-century Neo- platonist Scholarch, the last officially appointed Platonic Successor, revert to a tradition that seemingly disappears for well over three centuries? ~ In what ~As is well known, Damascius modifies Proclus' own exposition of the Parmenidean hypothe- ses, positing a first principle to which he gives the title ~the Ineffable."

This article explores the relationship between epistemic relativism and Pyrrhonian scepticism. It is argued that a fundamental argument for contemporary epistemic relativism derives from the Pyrrhonian problem of the criterion. Pyrrhonian scepticism is compared and contrasted with Cartesian scepticism about the external world and Humean scepticism about induction. Epistemic relativism is characterized as relativism due to the variation of epistemic norms, and is contrasted with other forms of cognitive relativism, such as truth relativism, conceptual relativism and (...) ontological relativism. An argument from the Pyrrhonian problem of the criterion to epistemic relativism is presented, and is contrasted with three other arguments for epistemic relativism. It is argued that the argument from the criterion is the most fundamental argument for epistemic relativism. Finally, it is noted how the argument of the present paper fits with the author’s previous suggestion that a particularist response to the Pyrrhonian sceptic may be combined with a naturalistic view of epistemic warrant to meet the challenge of epistemic relativism.

ABSTRACT This article recovers the discussion of the relationship between religion, human nature and happiness in the Scottish Enlightenment physician John Gregory’s (1724–1773) A Comparative View of Human Nature (1765). Through examining Gregory’s best-selling but understudied text, this article explores how the Aberdeen Enlightenment’s own branch of the wider Scottish ‘science of human nature’, centred at the famous Aberdeen Philosophical Society, was as deeply concerned with the study of religion as it was the philosophy of mind. Gregory examined how the (...) purported cultural spread of dogmatic scepticism, associated by the Aberdonians with David Hume, threatened individual happiness and social tranquillity by removing the crutch of religious belief upon which the multitude (though not the philosopher) depended. In doing so, it suggests that the contribution made by physicians to the Scottish Enlightenment’s engagement with religion has been unjustly ignored. (shrink)

I advocate scepticism about epistemic blame; the view that we have good reason to think there is no distinctively epistemic form of blame. Epistemologists often find it useful to draw a distinction between blameless and blameworthy norm violation. In recent years, this has led several writers to develop theories of ‘epistemic blame.’ I present two challenges against the very idea of epistemic blame. First, everything that is supposedly done by epistemic blame is done by epistemic evaluation, at least according (...) to a prominent view about the social role of epistemic evaluation. Parsimony considerations count against introducing an idle mechanism that does the same work as an existing one. Second, no current theory of epistemic blame includes a plausible account of the force of epistemic blame or the practices that could express it. I conclude that we should give up the notion of epistemic blame. (shrink)

Hegel’s Science of Logic is widely acknowledged as one of the greatest works of European philosophy. However, its contribution to arguably the most important philosophical problem, Pyrrhonian scepticism, has never been examined in any detail. Pyrrhonian Scepticism and Hegel's Theory of Judgement fills a great lacuna in Hegel scholarship by convincingly proving that the dialectic of the judgement in Hegel’s Science of Logic successfully refutes this kind of scepticism. Although Ioannis Trisokkas has written the book primarily for (...) those students of philosophy who already have an interest in Hegel’s epistemology and philosophy of language and/or his Science of Logic, it will also appeal to those who investigate the problem of scepticism independently of the Hegel corpus.

The ‘standard interpretation’ of John Taurek’s argument in ‘Should the Numbers Count?’ imputes two theses to him: first, ‘numbers scepticism’, or scepticism about the moral force of an appeal to the mere number of individuals saved in conflict cases; and second, the ‘equal greatest chances’ principle of rescue, which requires that every individual has an equal chance of being rescued. The standard interpretation is criticized here on a number of grounds. First, whilst Taurek clearly believes that equal chances (...) are all-important, he actually argues for a position weaker than the equal greatest chances principle. Second, the argument Taurek gives for the importance of equal chances ought to commit him to being more hospitable to the significance of numbers than he seems to be. Third, and as a result, Taurek should not have dismissed the significance of numbers but embraced a form of pluralism instead. Fourth, this result should be welcomed, because pluralism is more plausible than either the equal greatest chances principle or the saving the greater number principle. (shrink)

The idea that Western philosophy is a footnote to Plato is simplistic and inaccurate. Much of modern and contemporary epistemology owes a debt not so much to Platonism or Aristotelianism as to their antithesis: scepticism. Recent discussions in the history of philosophy have sparked a great deal of interest in the ancient sceptics, but until now they have been misunderstood and the significance of their philosophy not fully appreciated.

This paper (in English) highlights a hitherto neglected feature of Hegel’s 1807 Phenomenology of Spirit: its critique of the content of our basic categorial concepts. It focusses on Hegel’s semantics of cognitive reference in ‘Sense Certainty’ and his use of this semantics also in ‘Perception’ and ‘Force and Understanding’. Explicating these points enables us to understand how Hegel criticizes Pyrrhonian Scepticism on internal grounds.
