According to Hume, no knowledge attainable by human beings would ever justify rational belief in recurrent physical properties and causal effects. He arrived at this conclusion because he denied the possibility of knowing--but not the reality of--either the 'inner natures' or the 'secret powers' of objects which would enable one to intuit or to demonstrate a 'necessary connection' between the internal structures of objects and their observable properties, or between the causal powers of entities and their effects. The purpose of (...) this article is to show that while Hume's scepticism was justifiable in his day given the generally accepted limitations then of scientific inquiry and explanations, it no longer is reasonable in light of later scientific discoveries and theories. To a degree to which no eighteenth-century philosopher or scientist could anticipate, experimental inquiry has disclosed the inherent natures of objects and the underlying causes of phenomena that attest to the interconnectedness of physical reality and thus justify, at least to some extent, our instinctive beliefs in the uniformity of nature and predictability of events.

Two major arguments have been advanced for the claim that there is a transmission failure in G.E. Moore’s famous proof of an external world. The first argument, due to Crispin Wright, is based on an epistemological doctrine now known as ‘conservatism’. Proponents of the second argument, like Nicholas Silins, invoke probabilistic considerations, most important among them Bayes’ theorem. The aim of this essay is to defend Moore’s proof against these two arguments. It is shown, first, that Wright’s argument founders because (...) one of its premises, viz., conservatism, invites scepticism and must therefore be rejected. Then the probabilistic argument is challenged, not because its formal part is dubious, but rather on the grounds that it incorporates an unconvincing philosophical claim as an implicit premise. Finally, the two most promising objections to dogmatism—the negation of conservatism—are repudiated. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Giulio Castellani (1528-1586): A Sixteenth-Century Opponent of Scepticism CHARLES B. SCH1VHTT THE PROBLEMOF THE ORIGINS of scepticism in early modern philosophy has been a much debated issue. Sanches, Montaigne, Charron, and Bayle all contributed to the milieu which made it possible for the sceptical direction of thought to develop into such a potent force by the time of David Hume. The actual origins of modern scepticism, (...) which seem to go back to a slightly earlier date, lie in the confluence of several different intellectual movements during the early years of the sixteenth century: Christian anti-intellectualism, the reintroduction of the literary remains of the ancient sceptical tradition, the epistemological developments of scholastic nominalism, and certain inherent tendencies of Renaissance humanism. It is in the early decades of the sixteenth century that the seeds which later blossomed forth at the time of Hume originally took root. Hume himself merely reaped the harvest of several hundred years of sceptical preparation? Aside from certain manifestations of doubt which developed out of the epistemological theories of fourteenth-century nominalism, the origins of modern scepticism are generally held to date from the first publication of Sextus Empiricus' ancient summaries of Pyrrhonism during the decade of the 1560's. While it has previously been recognized that at least hints of scepticism were current in the fifteenth and early sixteenth centuries, the implications to be derived from this fact do not seem to have been adequately exploredT I shall not here go into these early manifestations of scepticism in a detailed way. Rather, I shall briefly touch upon a few little-known examples of the influence of ancient scepticism during the Reniassance and, then, I shall focus upon an early and practically neglected attack upon scepticism published before the first printings of Sextus Empiricus' writings. I shall discuss the circumstances of the composition of Giulio Castellani's anti-sceptical work, Adversus Marci TuIlii Ciceronis academicas questiones disi For a recent survey of early modem scepticism see Richard H. Popkin, The History o] Scepticism /tom Erasmus to Descartes (Assen: 1960). Of the large literature which connects scepticism with religious doubt during this period see especially Henri Busson, Les sources et le dgveloppement du rati~nalizme dar~ la litt~rature ]ran~aise de la Renaissance (Paris: 1957) and Don Cameron Allen, Doubt's Boundless Sea (Baltimore: 1964). The di.~cussionof this period seems to be the weakest part of Popkin's excellent book, particularly with regard to the treatment which he gives to Italian thought. See, also, his other articles, especially,"Skepticismand the Counter-Reformation in France," Archiv/fir Re/armationsgeschichte, LI (1960),58-86and "The High Road to Pyrrhonism," American Philosophical Quarterly, II (1965),18--32.In my forthcoming study, Gian]rancesco Pico (1469-1533) and His Critique o/Aristotle, I give a detailed analysis of the major representative of early sixteenthcentury scepticism. [151 16 HISTORY OF PHILOSOPHY putatio (1558), which antedates the first printing of Sextus Empiricus by four years, indicating that scepticism was already widespread enough to provoke an attack from the camp of the dogmatists. Furthermore, I shall analyze Castellani 's arguments in the context of the philosophical views of the mid-sixteenth century. Scepticism in the Early Renaissance Direct knowledge of the major ancient source of scepticism, the already mentioned writings of Sextus Empiricus, was rare throughout the Middle Ages. There are but two known extant Latin manuscripts which date before 1400. s From the fifteenth century we know of two more manuscripts, neither complete in itself, but together containing a significant portion of the extant writings of Sextus. 4 This evidence indicates that Sextus' works were not well known in translation before the first Latin editions of The Oulines o] Pyrrhonism (1562) and of Against the Mathematicians (1569). With the advent of an increased interest in and knowledge of Greek in Western Europe in the fifteenth century, we find a corresponding increase in the number of Greek manuscripts of Sextus Empiricus. Consequently, by the time of the first printings, an appreciable number of copies of his writings were available. Some were brought from the East, but a large number also are attributable to European scribes. 5 We also know that in... (shrink)

In this essay I wish to discuss the notions of utopia, especially the notion of epistemological utopia as Leszek Kołakowski described it in one of his paper. Epistemological utopia is not tantamount to the conception of perfect and unalterable knowledge. On the contrary, in its realm there is also a place for scepticism, because scepticism is a kind of epistemological utopia but à rebours. Epistemological fundamentalism and scepticism are indeed two opposite attitudes but they finally belong to (...) each other. Nevertheless, no one from these attitudes satisfy our epistemological theory. Bertrand Russell described similar situation in his short essay titled On optimism: we can accept at most together pessimist and optimist, never only one of them. Therefore that situation provides to the necessity of overcoming theoretical field of these two, foundational and sceptical, conceptions. In this article I use Wittgenstein’s ideas to search for a ‘new’ epistemological attitude. (shrink)

A Meta-Philosophy exploration of immanent and non-immanent features of first-order philosophy in terms of the values of non- values or negative values of Radical Scepticism, Nihilism and Minarchy, executed to show how philosophizing is done. -/- It misleadingly seems as if there is no progress in philosophy as, like in visual art, literature and music, each original thinker re-invents the entire discipline, its aims, purposes, values, methods, etc The nature of philosophical tools, methods, techniques and skills will be investigated (...) and applied in terms of radical scepticism. -/- This approach, set of values and attitude restrict the nature and the style of the meta-philosophizing. It will for example prevent the traditional development of a general, all-encompassing and all-inclusive metaphysical system. It also demands the focus on context-specific investigation of questions and the dealing of a particular problem in a certain context. -/- These limits require the re-interpretation of any philosophical tool being employed as well as the underlying assumptions and any pre-suppositions. -/- As far as possible philosophizing as an aspect of the processes of theorizing will be adhered to and realized. In chapter THREE I illustrate many-leveled and multi-dimensional thinking, that are to me as a visual artist as well, of extreme importance. These are the types of things employed by radical skepticism and that should be the form of philosophizing instead of and replacing traditional one-leveled and one-dimensional thinking, argumentation and reasoning.

Donald C. Ainslie's Hume's True Scepticism is a wonderful book—clearly written and forcefully argued—and was deservedly honored with Journal of the History of Philosophy's Book Prize for 2016. The focus of the book is part four of the first Book of Hume's Treatise, "Of the sceptical and other systems of philosophy." Ainslie develops an interpretation that takes seriously Hume's psychological claims, using them to solve puzzles in Hume scholarship, including the extent of Hume's scepticism, the nature of his (...) sceptical crisis, and the basis for his second thoughts on personal identity.I would encourage Ainslie to go further in tracing Hume's psychological explanations. In what follows, I will... (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.

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)

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.

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)

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)

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)

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.

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.

Saul_Jennifer, Scepticism and Implicit Bias.

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." For those interested in a.. (shrink)

Scepticism, Knowledge, and Forms of Reasoning is an attempt to resolve how best to respond to such vexing arguments, a matter on which there is no consensus ...

The classical arguments for scepticism about the external world are defended, especially the symmetry argument: that there is no reason to prefer the realist hypothesis to, say, the deceitful demon hypothesis. This argument is defended against the various standard objections, such as that the demon hypothesis is only a bare possibility, does not lead to pragmatic success, lacks coherence or simplicity, is ad hoc or parasitic, makes impossible demands for certainty, or contravenes some basic standards for a conceptual or (...) linguistic scheme. Since the conclusion of the sceptical argument is not true, it is concluded that one can only escape the force of the argument through some large premise, such as an aptitude of the intellect for truth, if necessary divinely supported.

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)

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)

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)

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.

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.

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)

The Modes of Scepticism is one of the most important and influential of all ancient philosophical texts. The texts made an enormous impact on Western thought when they were rediscovered in the 16th century and they have shaped the whole future course of Western philosophy. Despite their importance, the Modes have been little discussed in recent times. This book translates the texts and supplies them with a discursive commentary, concentrating on philosophical issues but also including historical material. The book (...) will be of interest to professional scholars and philosophers but its clear and non-technical style makes it intelligible to beginners and the interested layman. (shrink)

McDowell has argued that external world scepticism is a pressing problem only in so far as we accept, on the basis of the argument from illusion, the claim that perceiving that p and hallucinating that p involve a highest common factor.
