Sceptical arguments in epistemology typically employ sceptical hypotheses, which are rivals to our everyday beliefs so constructed that they fit exactly the evidence on which those beliefs are based. There are two ways of using a sceptical hypothesis to undermine an everyday belief, giving rise to two distinct sorts of sceptical argument: underdetermination‐based and closure‐based. However, both sorts of argument, as usually formulated in the literature, fall foul of evidential holism, for they ignore the crucial role of background beliefs. An (...) analogy with the philosophy of science makes this point explicit. There is no simple way to “holism proof” the two sceptical arguments. (shrink)

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)

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. (shrink)

The reason Descartes cites for invoking the demon argument in addition to the dream argument is that the demon argument is intended to broaden the scope of Descartes’ scepticism, to subsume additional beliefs under it. I present an additional, unfamiliar reason. There is, I argue, an important difference between the two sceptical arguments. It pertains not to their scope, but to their “depth”, to the kind of scepticism they are capable of inducing.

In his article ‘Healthy Scepticism’, James Franklin gives an admirable survey of thirteen kinds of attempts to refute what he calls ‘symmetry arguments for scepticism’, finding all of them inadequate. The symmetry argument that he proposes to test is given as follows: Firstly, it is possible that what we perceive is entirely an illusion created by a deceitful demon. Second, there is no reason to prefer the realist hypothesis to this one.

1. Contextualism seeks to acknowledge the power of sceptical arguments while permitting to be true at least some of the assertions of knowledge and justification we commonly make. It seems to me now just as if I am in an office in Edinburgh. According to the sceptic the claim that I am in fact in an office in Edinburgh is unjustified, since there is no reason I can give for this belief that is not also consistent with (or undermined by) (...) the alternative hypothesis that I am in fact on a beach in Hawaii being deceived by an evil demon into thinking that I am in an office in Edinburgh. Yet if I were.. (shrink)

The notion that the brain is a prediction error minimizer entails, via the notion of Markov blankets and self-evidencing, a form of global scepticism — an inability to rule out evil demon scenarios. This type of scepticism is viewed by some as a sign of a fatally flawed conception of mind and cognition. Here I discuss whether this scepticism is ameliorated by acknowledging the role of action in the most ambitious approach to prediction error minimization, namely (...) under the free energy principle. I argue that the scepticism remains but that the role of action in the free energy principle constrains the demon’s work. This yields new insights about the free energy principle, epistemology, and the place of mind in nature. (shrink)

According to veridicalism, your beliefs about the existence of ordinary objects are typically true, and can constitute knowledge, even if you are in some global sceptical scenario. Even if you are a victim of Descartes’ demon, you can still know that there are tables, for example. Accordingly, even if you don’t know whether you are in some such scenario, you still know that there are tables. This refutes the standard sceptical argument. But does it solve the sceptical problem posed (...) by that argument? I argue that it does not, because we do not know substantively more about the external world according to veridicalism than we do according to the sceptical argument. Rather, veridicalism merely reformulates what little knowledge we have. I then draw some general conclusions about the nature of the sceptical problem, the formulation of the standard argument, and the significance of this for some other, non-veridicalist strategies.

Various possibilities, that one is dreaming, that one is being deceived by a deceitful demon, that one is a brain in the vat being stimulated to think one has a body and is in a regular world, have been invoked to show that all one's experience-based beliefs might be false. Descartes in Meditation I advises that in order not to lapse into his careless everyday view of things he, or at least his meditator, should pretend that all his experience-based (...) beliefs, indeed all his ….

Within contemporary epistemology, notions of intellectual virtue have come to fulfill a prominent role in attempts to provide an account of knowledge. Notions of such virtue can vary, and one particular aspect of this variance concerns how to construe the relationship between the intellectual virtues and particular epistemic ends. The goal of this article is to defend an instrumental connection between the intellectual virtues and the epistemic end of true belief. One type of skeptical argument that attempts to sever this (...) connection, a Cartesian Demon argument, is considered. This Cartesian Demon argument will be summarized, as well as three responses to it. The claim that truth-conduciveness is a tenable criterion for identifying the intellectual virtues is then defended. It is acknowledged that the possibility of a Cartesian Demon does initiate scepticism, but that this scepticism is directed toward identifying specific intellectual virtues and not toward the instrumental connection between intellectual virtue and true belief.

In a recent paper McCain (2012) argues that weak predictivism creates an important challenge for external world scepticism. McCain regards weak predictivism as uncontroversial and assumes the thesis within his argument. There is a sense in which the predictivist literature supports his conviction that weak predictivism is uncontroversial. This absence of controversy, however, is a product of significant plasticity within the thesis, which renders McCain’s argument worryingly vague. For McCain’s argument to work he either needs a stronger version of (...) weak predictivism than has been defended within the literature, or must commit to a more precise formulation of the thesis and argue that weak predictivism, so understood, creates the challenge to scepticism that he hopes to achieve. The difficulty with the former is that weak predictivism is not uncontroversial in the respect that McCain’s argument would require. I consider the prospects of saving McCain’s argument by committing to a particular version of weak predictivism, but find them unpromising for several reasons. (shrink)

The external world sceptic tells some familiar narratives involving massive deception. Perhaps we are brains in vats. Perhaps we are the victim of a deceitful demon. You know the drill. The sceptic proceeds by observing first that victims of such deceptions know nothing about their external environment and that second, since we cannot rule out being a victim of such deceptions our- selves, our own external world beliefs fail to attain the status of knowledge. Discussions of global external world (...) scepticism tend to focus on the second step, where a number of well-known lines of resistance have been offered. But there has been little attention to the first, seemingly innocuous step. That will be the focus of this paper. Part one – sections 1, 2, and 3 – will explain why these standard narratives are not convincing examples of cases where there is no knowledge of the external world. In part two – section 4 – we shall undertake a useful case study. David Lewis’s ‘Elusive Knowledge’ is often thought of as presenting an epistemological vision that is somewhat friendly to external world scepticism: as Lewis himself presents things, there are contexts where external world knowledge ascriptions are uniformly false, and where true knowledge ascriptions are limited to either axiomatic truths or truths about our inner life. We examine his discussion in the light of the preceding reflections and show that the framework he presents is not so concessionary to global external world scepticism after all. (shrink)

The analysis presented here covers a vast number of aspects, or sub-questions, of the maddeningly frustrating general question, How can I be sure that, every time I believe something, such as that there are rocks, I am not deceived into so believing by a modern version of Descartes’ evil demon, i.e., a mad scientist who, by means of electrodes implanted in my brain, manipulates my beliefs? Numerous aspects are also analyzed of the standard objections to scepticism, such as (...) G. E. Moore’s common-sense affirmations of knowledge that he has two hands and the ad hominem question, If no beliefs are justified, then why do you, the sceptic, believe such propositions as the proposition that no beliefs are justified? The author not only concludes in favor of scepticism, but also erects strong arguments supporting the contention that, even apart from knowledge or supposed knowledge, truth itself is impossible. He concludes that, "to solve our problems [about the unwarranted use of terms such as ‘know', ‘believe', and ‘true'], either a new language should be developed and made available or at least an existing language should be radically changed in creative ways."—W.G.

In 1885, during initial discussions of J. C. Maxwell's celebrated thermodynamic demon, Whiting(1) observed that the demon-like velocity selection of molecules can occur in a gravitationally bound gas. Recently, a gravitational Maxwell demon has been proposed which makes use of this observation [D. P. Sheehan, J. Glick, and J. D. Means, Found. Phys. 30, 1227 (2000)]. Here we report on numerical simulations that detail its microscopic phase space structure. Results verify the previously hypothesized mechanism of its paradoxical (...) behavior. This system appears to be the only example of a fully classical mechanical Maxwell demon that has not been resolved in favor of the second law of thermodynamics. (shrink)

Imagine two urns, each with a thousand beads - in one all the beads are blue while in the other only one of the thousand is blue. If one of these urns is pushed forward (based on the toss of a fair coin) and the single bead then randomly drawn from it is blue, we must infer that it is a thousand times more probable that the urn pushed forward is the purely blue one. The hypothesis that this was instead (...) the urn with only one blue bead would require that the occurrence of the evidence, the blue bead being drawn, was something improbable - and it is improbable that something improbable is what has occurred. Next consider an example of only one urn with no prior description. By the same reasoning as above, if all the first beads randomly drawn are blue, it is becoming more and more probable that the beads in the urn are generally blue. (Otherwise something improbable would be happening in another colour not appearing; and what’s improbable is improbable.) It is therefore probable also that the next bead drawn will be blue. This is induction. As Hume would have said, we could not know a priori, given this evidence, that the next bead will be blue. But, as he overlooked, we can know a priori, given this evidence, that it is probable that the next bead will be blue. In neither urn example has the belief regarding the beads been formed as a Humean habit of expectation after many observations of beads. (In the first case there is only one observation. The second could be modified to have all the beads drawn out at once.) Rather the belief is a product of a priori reasoning about probability. Next imagine that a coin has been tossed a thousand times and landed heads every time. There was a fair and a loaded coin. According to the same reasoning, it is overwhelmingly more probable that the coin used was the loaded one. For that the fair coin had so landed is most improbable. The hypothesis that there is no external world makes the orderliness in my current experience improbable - much like getting all heads with a fair coin. (Uncaused sensation would most probably be chaotic.) The most probable hypothesis is that of things like those we believe in causing this orderliness - as the coin’s being loaded would have caused all heads. The hypothesis that my experience has been made to take this pattern by a Cartesian malicious demon or by scientists controlling my brain in a vat can only falsely seem to make the character of the experience probable by sneaking in an inherently improbable ad hoc specification that this sort of pattern of experience was that which they were aiming at producing - like an ad hoc specification that the fair coin was one that by chance landed heads all thousand times. We may thus reject such hypotheses as improbable. So this is the problem of induction solved and scepticism answered through a priori reasoning. (shrink)

What is the role of sceptical scenarios—dreams, evil demons, brains in a vat—in scep- tical arguments? According to the error view, sceptical scenarios illustrate the possibil- ity of massive falsity in one’s beliefs, whereas according to the ignorance view, they illustrate the possibility of massive ignorance not necessarily due to falsity. In this paper, the ignorance view is defended by surveying the arguments in favour of it and by replying to two pressing objections against it. According to the first objection, (...) the ignorance view illicitly introduces the kk-principle into sceptical arguments. In reply I argue that kk is not less plausible than its main rival, the closure principle. According to the second objection, relying on veridical ignorance-possibilities contradicts the transparency of belief. In reply I introduce a version of transparency that is consistent with the ignorance view. (shrink)

If p is false, it isn't evidence for anything. This view is central in one important response to a familiar sceptical argument. I consider and reject various motivations for refusing to accept this view – proposals arising from, e.g., our practice of providing rationalising explanations of people's beliefs, various locutions appearing to relativise evidence to persons, the significance of people's mental states for attributions of reasons to them, and the role of evidence in epistemic principles and requirements. I close by (...) considering responses to the ‘New Evil Demon Argument’. What emerges is an affirmation of the principle that p doesn't provide evidence unless it is true, a response to an important version of the Evil Demon argument for scepticism, and also a deeper interpretation of our epistemic practice.

Both in ethics and in epistemology one source of scepticism in its contemporary version is the realization, often belated, of the full consequences of atheism. Modern non-moral philosophy looks back to Descartes as its father figure, but disowns the Third Meditation. But if God does not underwrite one's cognitive powers, what does? The largely unknown evolution of them, which is just a version of Descartes’ unreliable demon? “Let us … grant that all that is here said of God (...) is a fable, nevertheless in whatever way they suppose that I have arived at the state of being that I have reached, whether they attribute it to fate or to accident, or make out that it is by a continual succession of antecedents, or by some other method — since to err and deceive oneself is a defect, it is clear that the greater will be the probability of my being so imperfect as to deceive myself ever, as is the Author to whom they assign my being the less powerful”.

The orthodox position in epistemology, for both externalists and internalists, is that a subject in a ‘bad case’—a sceptical scenario—is so epistemically badly off that they cannot know how badly off they are. Ofra Magidor contends that externalists should break ranks on this question, and that doing so is liberating when it comes time to confront a number of central issues in epistemology, including scepticism and the new evil demon problem for process reliabilism. In this reply, I will (...) question whether Magidor’s argument should persuade externalists, whether it really engages with the orthodox view on what subjects in bad cases can know, and whether the dispute is, as Magidor insists, a significant one for contemporary epistemology.

Klein aims to refute scepticism on its own terms by showing that, even if we grant the sceptic as much as possible in the way of strong necessary conditions for knowledge and weak sufficient conditions for the defeat of knowledge claims, the case for scepticism is still defective. In this I think he is totally successful at least as regards the two forms of direct scepticism he deals with. On the third type of scepticism, iterative (...) class='Hi'>scepticism, I think his results are more open to question--but only because I think he has conceded too much to the sceptic in the course of the argument. The main sceptical argument Klein is concerned with is the evil demon argument and its associated defences. Klein's argument in his two central chapters is detailed, rigorous and often labyrinthine. The long section on the concept of justification is hard to follow and might have benefitted from further formalization, especially since parts of it and the following section consist of derivations. One consequence of Klein's cautious manner of proceeding is that reviewers are compelled to take drastic short-cuts in terminology and exposition. One hopes this will not produce distortion, but the reader who fears it has is well advised to read the book, which more than repays careful study. (shrink)

In this paper I offer a solution to scepticism about the world which neither embraces idealism, nor ends in a stalemate, nor begs the question against the sceptic. In the first part of the paper I explicate the sceptical argument and try to show why it has real force. In the next part of the paper I propose a version of the relevant possibilities approach to scepticism. The central claim of the proposed solution is that a sceptical possibility (...) undermines knowledge only if the possibility is true in some close possible world. But since there is no reason to believe that I am deceived by an evil demon or that I am a brain in a vat in some close possible world, there is no reason to accept an essential premise of the sceptical argument, i.e. that the sceptical scenarios are relevant possibilities. Finally, I argue that the solution proposed does not embrace idealism, end in a stalemate, or beg the question. (shrink)

In many cultures and societies, there has been, at least intuitively, some connection between what is believed to be sacred and divine and the highest ideals of the good, justice, and the right. Moral beliefs and values are often sensed to have ultimate importance, as somehow holy, and thus the examination of those beliefs, values, and sensibilities would be a proper starting point for natural theology. The inverse is also true: reflection on and the experience of evil and viciousness have (...) provoked many to explore the negation of the holy and divine, namely, the demonic, in order to avert moral scepticism and despair that evil might prevail. This chapter, which examines an approach to natural theology undertaken with respect to morality, begins by clarifying what is meant by approaching natural theology through ethics. It then discusses ethical approaches to natural theology, theistic ethics, ethical theism, aspiration and ethics, and mediating theology, and concludes with prospects for future thought. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Cartesian Skepticism from Bare PossibilityRobert WachbritIn making his case for skepticism, Peter Unger offers the following exotic case as one which “conforms to a familiar, if not often explicitly artic-ulated pattern or form” of skeptical reasoning: 1 imagine that there is an evil scientist who deceives subjects into falsely believing that there are rocks. Living in a world bereft of rocks, he induces belief in their existence using electrodes (...) implanted into the appropriate parts of the subjects’ brai ns, protoplasm, or systems through which he sends patterns of electrical impulses in accord with his deceptive designs. Unger then offers the following argument, which is supposed to instantiate the pattern or form of this kind of skeptical reasoning:If you know that there are rocks, then you can know that there is no such scientist doing this to you. But no one can ever know that there is no evil scientist who is, by means of electrodes, deceiving him into falsely believing there to be rocks. So... you never know that there are rocks. But of course we have chosen our person, and the matter of there being rocks, quite arbitrarily, and this argument... may be generalized to cover any external matter at all. From this, we may conclude... that nobody knows anything about the external world. 2After presenting this case and articulating its form, Unger claims that “this argument is the same in form as the ‘evil demon’ argument in Descartes’s [End Page 109] Meditations; it is but a more modern, scientific counter-part, with its domain of application confined to matters concerning the external world.” He then proceeds to describe Descartes’s argument as “the most compelling sceptical argument the phil osophical literature has to offer,” calling it in fact “the classical argument for scepticism.” 3These claims may seem a little bit surprising; for it is not obvious, even from the most careful attention to the text, that what is written about the evil demon in the First Meditation constitutes a skeptical argument at all, and the scholarly literature is generally, and perhaps surprisingly, quite confusing about just what is going on at the end of the First Meditation. Further, rather than being exceedingly compelling as Unger thinks, arguments of this form are not only assiduously avoided by Descarte s during his descent into skepticism but are in fact, as I shall argue with some help from Descartes, weak and considerably less compelling than the kind of skeptical challenges Descartes actually offers.My purpose in this paper, then, is to make two related points, one historical and the other philosophical. First, I will try to demonstrate, on the basis of both textual and critical evidence, that Descartes was not offering a (further and final) skeptica l argument when he invented his demon. I will try to exhibit some of the confusions in the scholarly literature about the text of the last three paragraphs of the First Meditation and, by so doing, support Gouhier’s position that the idea of the demon “ha s no metaphysical significance; it is purely a methodological artifice which permits doubt to continue....” 4 Second, I will show that embodied in Descartes’s rejection of this kind of skeptical reasoning is the very reason for its weakness, a weakness that should prevent it from being considered, as Unger considers it, the classical form of skeptical argument. The inventions of the First Meditation still exercise considerable hold on our philosophical imaginations. I hope to show that, at least as far as the demon is concerned, Descartes would have been surprised at some of the most conventional and entrenched scholarly interpretations given his use of it and not at all sympathetic to its employment in a skeptical argument. Lest the demon seem an old and tired subject of philosophical scrutiny, let me beg the reader’s indulgence by promising both a deeper than usual look into the text of the end of the First Meditation and some significant conclusions about Cartesian skepticism that are hardly commonplace and thus neither old nor tired.

A familiar anti-sceptical response (à la Sosa) to radical sceptical scenarios employs the safety of knowledge. Radical sceptical scenarios are purported to be too modally remote to really threaten knowledge of ordinary propositions. Why? Because knowledge requires safety, and safety requires the target belief to be true in all nearby possible worlds, but radical sceptical scenarios purportedly take place at distant possible worlds. Hence, the safety theorist claims that radical sceptical scenarios don’t challenge our knowledge of ordinary propositions. But it's (...) alleged by Sosa and others that there's one radical sceptical scenario that can’t be dismissed so easily: the dream scenario. After all, unlike evil demons and brains in vats, ‘dreaming is a daily part of our lives…it is too close for comfort’. In this paper, I sketch an argument to the effect that there's good reason to think that the dream of dream scepticism describes a modally remote possibility, in which case I argue that if the safety-based anti-sceptical response is successful against the evil demon sceptical scenario, the brain in a vat sceptical scenario, and other Cartesian sceptical scenarios in this mould, then it's successful against the dream sceptical scenario as well.

Philosophers continue to locate themselves on a landscape in which scepticism is a prominent feature. By treating sceptical scenarios, from evil demons to brains-in-vats, as "real possibilities" that would, if actual, suffice to "explain our experience as of a world beyond our senses", we can locate the strong independence of the world from knowledge characteristic of metaphysical realism. But, by taking scepticism this seriously, realists deprive themselves of any justification for other theses they nonetheless continue to advocate. In (...) order to advance beyond scepticism, metaphysical realists must then treat sceptical scenarios as mere logical possibilities, but by doing so they jettison the strong independence of the world that characterizes their own form of realism. This "concurrent need to admit and deny a thesis, especially a sceptical one", is the "neurosis" or "epistemic dissociative disorder" of Michael Hymers's title. Hymers makes a persuasive case for regarding this simple story as the right diagnosis for a succession of ills afflicting self-described metaphysical realists. On his telling of the tale, the mind-independence of the world needed for metaphysical realism requires taking scepticism seriously; but accompanying positive theses require that the same seriousness be dampened.

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.

Facts about justification are not brute facts. They are epistemic facts that depend upon more fundamental non-epistemic facts. Internalists about justification often argue for mentalism, which claims that facts about justification supervene upon one’s non-factive mental states, using Lehrer and Cohen’s :191–207, 1983) New Evil Demon Problem. The New Evil Demon Problem tells you to imagine yourself the victim of a Cartesian demon who deceives you about what the external world is like, and then asks whether you (...) nevertheless have justification for your beliefs about the external world. Internalists and externalists agree that there is something that is epistemically good or valuable about both your actual beliefs and your beliefs in the demon scenario. Internalists claim that the epistemic property which these sets of beliefs share most intuitively should be thought of as sameness of justification. Externalists, on the other hand, reject this claim, usually either by challenging the internalist intuition directly, or by arguing that there is a more plausible way to think about the epistemic property in question. Recently, both kinds of externalist objection have been raised against the argument from the New Evil Demon Problem for mentalism. The goal of this paper is to defend the argument against three prominent objections—a pair of which is offered by Littlejohn :399–434, 2009) and one by Williamson Rationality and the good: critical essays on the ethics and epistemology of Robert Audi, Oxford University Press, Oxford, 2007; in: Dutant J, Dohrn D The new evil demon, Oxford University Press, Oxford, 2016).

The aim of this paper is to clarify Kierkegaard’s concept of demonic despair (and demonic evil) and to show its relevance for discussions of the guise of the good thesis (i.e. that in f-ing intentionally, we take f-ing to be good). Contemporary discussions of diabolic evil often emphasise the phenomena of despair and acedia as apparent counter-examples to the guise of the good. I contend that Kierkegaard’s analysis of despair is relevant to these discussions, because it reconciles demonic (extreme) despair (...) and acedia with the guise of the good. In The Sickness unto Death, Kierkegaard provides an influential, systematic account of despair that relates evil, despair, and acedia to each other. Michelle Kosch argues that this account goes beyond Kierkegaard’s German predecessors by introducing a concept of diabolic evil and despair. By contrast, the present paper argues that Kierkegaard takes diabolic evil to be impossible, although he offers a rich analysis of the demonic that resembles diabolic agency. Still, Kierkegaard’s analysis rests on ontological assumptions about the nature of the good that belong to a Platonico-Christian tradition that is controversial today. (shrink)

Saul_Jennifer, Scepticism and Implicit Bias.

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.

In this paper, I defend externalist accounts of justified belief from Cohen's new evil demon objection. While I think that Cohen might be right that the person is justified in believing what she does, I argue that this is because we can defend the person from criticism and that defending a person is a very different thing from defending a person's attitudes or actions. To defend a person's attitudes or actions, we need to show that they met standards or (...) did not violate norms. Intuitions about whether we can defend a person from criticism are a poor guide when it comes to determining whether norms were violated or standards were met. It turns out that even radical forms of externalism about justification are compatible with the intuitions that Cohen's example elicits. Properly understood, those intuitions show that the believer should be excused from criticism (and excused for failing to believe with adequate justification). (shrink)

And, he says, these opinions constitute “the foundation” (T 646) for his treatment of morals and politics in Book III.2 The mystery arises, however, because in the actual text of [End Page 469] Book II Hume never spells out what makes his opinions on the passions “new and extraordinary,” nor why they are foundational for his moral theory.Thus some of his interpreters, notably Norman Kemp Smith, conclude that Hume was simply mistaken in his assessment of his treatment of the passions. While his accounts of the will and of motivation (in the early Sections of Part iii of Book II) are significant, Kemp Smith takes the extended analysis of the indirect passions to spring merely from his misplaced enthusiasm for associationist psychology. As such, the philosophical lessons to be learned from the first two Parts of Book II are slim.3 Páll Árdal, in contrast, tries to construct for Hume what he seems to have omitted—a philosophical rationale for his obvious interest in the indirect passions. Árdal starts by drawing attention to the role these passions play in Hume’s moral philosophy, in particular, his repeatedly connecting the indirect passions to the moral sentiments of approval and disapproval. Árdal concludes that Hume means to equate the moral sentiments with particular kinds of indirect passions. The first two Parts of Book II are of interest, on Ardal’s reading, because it is there that he shows us how moral sentimentalism can be founded on something more fully naturalistic than Hutcheson’s somewhat mysterious “moral sense.”4I argue against Árdal’s interpretation in §2. But this reopens the problem of accounting for Hume’s interest in the indirect passions. I offer my view in §§3–5 where, like Árdal, I provide a reconstruction of Hume’s discussion of these passions in order to show how it has an underlying philosophical motivation. My claim is that Hume relies on the indirect passions to explain how we form beliefs about persons as bearers of features that make them into who [End Page 470] they are. It is by feeling an indirect passion towards someone that we think of her as more than accidentally related to some quality, such as her country, her riches, her family, or even her character traits. In support of my interpretation I point to the many parallels Hume draws between the indirect passions and the associative mechanism he offers to explain our forming causal beliefs (I.iii). And I suggest that, just as Hume’s associative explanation of causal beliefs is necessitated by his scepticism about intrinsic “necessary connexions,” so also his associative mechanism for our beliefs about persons—the indirect passions—is necessitated by a certain kind of scepticism about persons. This is not the scepticism about persons that we find in “Of personal identity” (I.iv.6), where Hume argues against the view that our perceptions inhere in a simple soul; it is rather a scepticism about there being intrinsic features of persons that define them as who they are.But, before I explain in more detail what my claim amounts to, it will help to have available a brief description of the mechanism that Hume’s takes to explain the indirect passions.1. THE MECHANISM FOR THE INDIRECT PASSIONSA passion, for Hume, is a simple impression felt in response to various circumstances. Because of their simplicity, we cannot define passions by putting their characteristic feeling into words; instead, Hume thinks, we can only delineate “such circumstances, as attend them” (T 277). Passions are indirect if those circumstances include as an outcome the focusing of attention onto a person... (shrink)
