In a recent article, Steel, Buchak and Eyal argue that current levels of uncertainty do not present a good reason to bar controlled human infection trials of COVID-19 vaccines from proceeding. We argue that their argumentation for this conclusion is flawed. SBE are mistaken about the effects which different forms of ignorance have on participants’ ability to provide valid informed consent. Decision-makers considering whether to allow such trials, we argue, must ultimately consider the likelihood that consent to participation (...) in such trials under current conditions would be valid, and whether this likelihood is high enough to permit such trials. This is a question that SBE completely ignore. We conclude that there indeed are valid concerns about conducting CHI trials given the current state of knowledge about COVID-19, concerns which SBE fail to address. (shrink)

Eleonore Stump argues in her article in this volume that Aquinas’s theory of knowledge is not classical foundationalism, as it has sometimes seemed to be, but, instead, a version of reliabilism. I'm convinced that her thesis is important and well-supported, and it has led me to begin a re-examination of one aspect of Aquinas’s theory of knowledge from the new viewpoint Stump’s work provides. I think the results tend to confirm her account while revealing further details of Aquinas’s reliabilism.My (...) topic is not reliabilism itself. Instead, I am focusing on Aquinas’s account of the reliability of the fundamental operations of the two human cognitive faculties, sense and intellect. Accounts of cognitive reliability have a place in most theories about the justification of belief, of course, and so they are found in more than one sort of epistemology; but reliabilism might be said to need them most.

Purpose. The purpose of this study is to investigate how professionals learn from varying experiences with errors in health-care digitalization and develop and use negative knowledge and digital ignorance in efforts to improve digitalized health care. Design/methodology/approach. A two-year qualitative field study was conducted in the context of a public health-care organization working with digital patient communication. The data consisted of participant observation, semistructured interviews and document data. Inductive coding and a theoretically informed generation of themes were applied. (...) Findings. The findings show that both health-care and digital communication professionals learn through experiences with digital “rule-” and “knowledge-based” errors in patient communication and develop negative knowledge and awareness of digital ignorance. In their joint efforts, they use negative knowledge to “bend the rules” and to explore digital ignorance in efforts to improve patient communication. Originality/value. This study provides insight into the importance of collaboration between professionals with varying experience of errors in digitalizing patient communication. Such collaboration is required to acknowledge own shortcomings and create complementary negative knowledge to improve digital patient communication. This is particularly important when working with innovative digitalization in health care. (shrink)

I seek to show that the skeptical argument from error turns crucially on the following assumption: because Bill1 with the same degree of evidence as Bill2 failed merely by virtue of John's1 absence to know that John1 would be at the party, then Bill2 must have got things right by coincidence if he got them right at all, as to the actual attendance of John2. And so he does not have knowledge. But the conclusion that coincidence entered here (...) is a non-sequitur. (shrink)

In this paper we show that an essential aspect of solving the problem of uncritical acceptance of expert opinions that is at the root of the ad verecundiam fallacy is the need to disentangle argument from expert opinion from another kind of appeal to authority. Formal and computational argumentation systems enable us to analyze the fault in which an error has occurred by virtue of a failure to meet one or more of the requirements of the argumentation (...) scheme from argument from expert opinion. We present a method for enhancing this capability by showing how arguments from expert opinion are related to, but different from, arguments from deontic authority. (shrink)

The earliest debate on the argument from ignorance emerged in Islamic rational theology around the fourth/tenth century, approximately seven centuries before John Locke identified it as a distinct type of argument. The most influential defences of the epistemological principle that are encountered in Mu sources, particularly r and al-Malimar, and was eventually classed as a fallacy by Fakhr al-Dzyat al-l contains the most definitive and comprehensive refutation of classical kalm summa. According to the eighth/fourteenth-century historian Ibn Khaldarism took (...) during the sixth/twelfth century. (shrink)

In his Dialogues and Natural Religion, David Hume offered an inductive argument claiming that the observed mixture of good and evil in the world inductively justifies belief in indifferent first causes. The existence of a benevolent, omniscient God is rejected because it is much less probable. I show that a more comprehensive analysis of Hume’s argument applying Bayes’s Theorem indicates that if the good in our world greatly outweighs the evil, theists can then claim the inductive evidence actually provides confirmation (...) for classical theism. I provide some reasons for believing that good greatly exceeds evil. Views that good modestly exceeds evil or is balanced by evil are also considered. (shrink)

_Arguments from Ignorance _explores the situations in which the argument from ignorance functions as a respectable form of reasoning and those in which it is indeed fallacious. Douglas Walton draws on everyday conversations on all kinds of practical matters in which the _argumentum ad ignorantiam _is used quite appropriately to infer conclusions. He also discusses the inappropriate use of this kind of argument, referring to various major case studies, including the Salem witchcraft trials, the McCarthy hearings, (...) and the Alger Hiss case. This book makes an original contribution in the areas of argumentation theory and informal logic, contending that, despite its traditional classification as a fallacy, the argument from ignorance is a genuine, very common, and legitimate type of argumentation with an identifiable structure. But the book is also interdisciplinary in scope, explaining many widely interesting and controversial subjects in artificial intelligence, medical education, philosophy of science, and philosophy of law in a clear way that makes it accessible to a broad range of readers.

Reber and Alcock have recently made a sharp attack on the entire psi literature, and in particular a recent overview by Cardeña of the meta-analyses across various categories of psi. They claim the data are inherently fl awed because of their disconnect with our current understanding of the world. As a result, they ignore the data and identify key scientific principles that they argue clash with psi. In this Commentary, I argue that these key principles are diffi cult to apply (...) in areas where our understanding remains poor, especially quantum mechanics and consciousness. I also explore how the psi data may fi t within these two domains. (shrink)

The purpose of this paper is twofold: to give a good account of the argument from ignorance, with a presumptive argumentation scheme, and to raise issues on the work of Walton, the nature of abduction and the concept of epistemic closure. First, I offer a brief disambiguation of how the terms 'argument from ignorance' and 'argumentum ad ignorantiam' are used. Second, I show how attempts to embellish this form of reasoning by Douglas Walton and A.J. Kreider (...) have been unnecessary and unhelpful. Lastly, I offer a full and effective account of the argument from ignorance and discuss the lessons of the analysis.Le but de cet article est double: donner un bon compte rendu de l'argument par l'ignorance, avec un schème d'argumentation présomptif, et soulever des questions sur certains aspects de l’œuvre de Walton, la nature des raisonnements abductifs et le concept de fermeture épistémique. Premièrement, j'offre une brève désambiguïsation de la façon dont les termes «argument par l'ignorance» et «argumentum ad ignorantiam» sont utilisés. Deuxièmement, je montre comment les tentatives de Douglas Walton et de A.J. Kreider d'embellir cette forme de raisonnement ont été ni nécessaires et ni utiles. Enfin, j'offre un compte-rendu complet et utile de l'argument par l'ignorance et je discute des leçons de l'analyse. (shrink)

In his book Wittgenstein on Rules and Private Language, Saul Kripke develops a famous argument that purports to show that there are no facts about what we mean by the expressions of our language: ascriptions of meaning, such as “Jones means addition by ‘+’” or “ Smith means green by ‘green’”, are according to Kripke’s Wittgenstein neither true nor false. Kripke’s Wittgenstein thus argues for a form of non- factualism about ascriptions of meaning: ascriptions of meaning do not purport to (...) state facts.1 Define semantic realism to be the view that ascriptions of meaning are apt to be assessed in terms of truth and falsity, and are, at least in some instances, true. Semantic realism, thus defined, is a form of cognitivism about semantic judgement, according to which judgements ascribing meaning express beliefs, states apt for assessment in terms of truth and falsity. Kripke’s Wittgenstein thus argues against semantic realism, and in favour of a form of semantic non-cognitivism. However, another form of opposition to semantic realism accepts that semantic judgements express beliefs but asserts that those beliefs are systematically and uniformly false.2 This cognitivist form of opposition to semantic realism is similar to the error-theoretic form of opposition to moral realism mooted by J.L. Mackie in the first chapter of his Ethics: Inventing Right and Wrong. In this paper I will investigate whether there is a plausible analogue of Mackie’s “argument from queerness” that can be used to make a case for an error-theory of semantic judgement. In §2 I set out what I take to be Mackie’s argument from queerness against moral realism. In §3 I argue that there is no straightforward and plausible analogue of that argument that would justify an error theory about ascriptions of meaning. In §4 and §5 I defend the argument of §3 against an objection developed in a recent paper by Daniel Whiting. (shrink)

In this paper I defend what I call the argument from epistemic reasons against the moral error theory. I argue that the moral error theory entails that there are no epistemic reasons for belief and that this is bad news for the moral error theory since, if there are no epistemic reasons for belief, no one knows anything. If no one knows anything, then no one knows that there is thought when they are thinking, and no (...) one knows that they do not know everything. And it could not be the case that we do not know that there is thought when we believe that there is thought and that we do not know that we do not know everything. I address several objections to the claim that the moral error theory entails that there are no epistemic reasons for belief. It might seem that arguing against the error theory on the grounds that it entails that no one knows anything is just providing a Moorean argument against the moral error theory. I show that even if my argument against the error theory is indeed a Moorean one, it avoids Streumer's, McPherson's and Olson's objections to previous Moorean arguments against the error theory and is a more powerful argument against the error theory than Moore's argument against external world skepticism is against external world skepticism.

We defend the Simulation Theory of Mind against a challenge from the Theory Theory of Mind. The challenge is that while Simulation Theory can account for Theory of Mind errors, it cannot account for their systematic nature. There are Theory of Mind errors seen in social psychological research with adults where persons are either overly generous or overly cynical in how rational they expect others to be. There are also Theory of Mind errors observable in developmental data drawn (...) class='Hi'>from Maxi-type false belief tests. We provide novel responses to several examples showing that Simulation Theory can answer these challenges. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy, argument from fallacy. Also known as argumentum ad logicam, argument to logic, fallacy fallacy, and fallacist's fallacy, the argument from fallacy occurs when one reasons that because the argument for some conclusion is fallacious, the conclusion of that argument is false. Truth and falsity are features of claims. Fallacies are errors in reasoning, not errors about truth or falsity. That is, if someone has committed a fallacy, (...) then he has made an error in reasoning; but it does not follow that he has made a factual error. As a deductive argument, fallacy of affirming the consequent is invalid ‐ one cannot draw/infer the conclusion from the premises ‐ and yet the conclusion is true. As such, it should be clear that poor reasoning (committing a fallacy) does not entail a false conclusion. (shrink)

By explaining the argument from ignorance in terms of the presumption of innocence, many textbooks in argumentation theory suggest that some arguments from ignorance might share essential features with some types of presumptive reasoning. The stronger version of this view, suggesting that arguments from ignorance and presumptive reasoning are almost indistinguishable, is occasionally proposed by Douglas Walton. This paper explores the nature and limits of the stronger proposal and argues that initial presumptions (...) and arguments from ignorance are not closely connected. There are three main reasons. First, the argument from ignorance, unlike typical presumptive reasoning, is a negative kind of inference. Second, the typical initial presumption is sensitive to a broader set of defeaters and thus assumes a higher standard of acceptability. Third, in dialectical terms, initial presumption and argument from ignorance bring different attacking rights and obligations. I conclude that Waltonian intuition is unsupported or, at best, is limited only to practical presumptions and practical arguments from ignorance. (shrink)

In a series of papers (two of them in previous ESA Proceedings), I have been defending a fictional artifactualist position according to which fictional characters (like Prince Bolkonsky in Tolstoy’s War and Peace are non-concrete, human created objects (which are commonly labeled abstract artifacts). In this paper, I aim to bring together from my previous work two lines of defending fictional artifactualism: that (for the fictional artifactualist) making room for (i) authorial creation and for (ii) inadvertent authorial creation are (...) tenable moves. Indeed, instances of authorial creation (intentional or inadvertent) are what we expect if we accept Saul Kripke’s general view about what determines the reference of proper names, and this view’s consequences for fictional names. Fictional artifactualism emerges as our best choice if we want to admit fictional characters in our ontology and are sympathetic to Kripke’s general view about proper name reference. Fictional artifactualists having taken these two conditions on board need not worry about these features of their view: that authors sometimes create fictional characters and sometimes do so inadvertently.

In his recent book Error Theory: History, Critique, Defence, Jonas Olson attempts to revive the argument from queerness originally made famous by J.L. Mackie. In this paper, we do three things. First, we eliminate four untenable formulations of the argument. Second, we argue that the most plausible formulation is one that depends crucially upon considerations of parsimony. Finally, we evaluate this formulation of the argument. We conclude that it is unproblematic for proponents of moral non-naturalism—the target of the (...) argument from queerness. (shrink)

This investigation uses the technique of the profile of dialogue as a tool for the evaluation of arguments from ignorance (also called lack-of-evidence arguments, negative evidence, ad ignorantiam arguments and ex silentio arguments). Such arguments have traditionally been classified as fallacies by the logic textbooks, but recent research has shown that in many cases they can be used reasonably. A profile of dialogue is a connected sequence of moves and countermoves in a conversational (...) exchange of a type that is goal-directed and can be represented in a normative model of dialogue. Selected case studies are used to probe special features of using the profile technique as applied to arguments from ignorance of a kind that occur frequently in everyday conversational exchanges. One of these special features is the use of Gricean implicature. Another is the need to use negative profiles of argument. (shrink)

In this paper, I explain the curious role played by the Argument from Absolute Terms in Peter Unger's book Ignorance, I provide a critical presentation of the argument, and I consider some outstanding issues and the argument’s contemporary significance.

Chief executive officers (CEOs) are typically paid great amounts of money in wages and bonuses by commercial companies. This is sometimes defended with an argument from peer comparison; roughly that “our” CEO has to be paid in accordance with what other CEOs at comparable companies get. At first glance this seems like a poor excuse for morally outrageous pay schemes and, consequently, the argument has been ignored in the previous philosophical literature. In contrast, however, this article provides a partial (...) defence of the argument from peer comparison. Moreover, it is demonstrated how a serious consideration of this argument sheds further light on both incentive- and desert-based theories of just pay. (shrink)

The argument from ignorance mounted by John Schellenberg argues from the existence of non-faulty unbelief to the non-existence of God, from the fact of atheism or agnosticism to the truth of atheism. It relies on two putative conceptual relations: between the idea of love and that of personal relationship, and between personal relationship and existential belief on each side of the relation concerning the other relatum. I argue that each is debatable, and so the argument cannot (...) proceed. (shrink)

J. L. Mackie argued that moral thought and discourse involve commitment to an especially robust kind of normativity, which is too weird to exist. Thus, he concluded that moral thought and discourse involve systematic error. Much has been said about this argument in the last four decades or so. Nevertheless, at least one version of Mackie’s argument, specifically the one focusing on the intrinsic weirdness of the relevant kind of normativity, has not been fully unpacked. Thus, more needs to (...) be said about the issue of how to interpret Mackie’s argument. Moreover, I argue that by looking closely at Mackie’s discussion, we can extract two distinct versions of the argument which together present a tougher, and also more precise, challenge for moral realism than extant versions. In this paper I thus revisit Mackie’s discussion with an eye to making progress on an important issue in contemporary metaethics. (shrink)

This paper challenges the viability of argument from supervenience in defense of a physicalist position on the place of qualia, the subjective properties of consciousness, in a physical or material world. Physicalism, being an ontological thesis that asserts that the only things that really exist are either physical entities or properties, affirms that every mental attribute must be a physical attribute. However, the existence of a quale as an attribute of a mental state falsifies this affirmation. The physicalist argues (...) that qualia supervene on the physical properties in the human body, and that any problem about qualia is, just like any other scientific problem, resolvable scientifically, either in principle or in practice. This paper argues that supervenience is merely a report of the nature of reality, and not a justificatory ontological affirmation that qualia supervene on physical properties. The paper begins with a short description of physicalism and an account of qualia as distinctive character of consciousness. It further articulates and examines the physicalists’ use of the argument from supervenience to establish that qualia supervene on the physical elements in the world. The concluding part shows the errors in the argument from supervenience, and its implication for the truth of physicalism. (shrink)

The argument from evil, though it is the most effective rhetorical argument against orthodox theism, fails to demonstrate its conclusion, since we are unavoidably ignorant whether there is more evil than could possibly be justified. That same ignorance infects any claims to discern a divine purpose in nature, as well as recent attempts at a broadly Irenaean theodicy. Evolution is not, on neo-Darwinian theory, intellectually, morally, or spiritually progressive in the way that some religious thinkers have supposed. To (...) suppose so, indeed, is to misidentify the evils we should fear. But though we should neither conceal the evils of the world nor offer any consequentialist justification of them, we may still reasonably maintain an orthodox theism. Evil is not created so that otherwise unattainable goods may come, but is an unavoidable byproduct of creation which it is – or may be – God's purpose to redeem. (shrink)

I argue that the Standard View of ignorance is at odds with the claim that knowledge entails truth. In particular, if knowledge entails truth then we cannot explain away some apparent absurdities that arise from the Standard View of ignorance. I then discuss a modified version of the Standard View, which simply adds a truth requirement to the original Standard View. I show that the two main arguments for the original Standard View fail to support this (...) modified view. (shrink)

The author explores and criticises two arguments from ambiguity: S. Pinker’s argument from ambiguity in support of the ‘Language of Thought’ hypothesis, and the argument from ambiguity proposed by K. P. Parsons against Davidsonian ‘semantics of truth-conditions’. Leaning primarily on G. Harman and D. Davidson he aims to demonstrate that the Pinker/Parsons arguments share a common strategy, on the one hand, and imply and/or suggest, as he claims, an implausible view of ambiguity, on the other. (...) Discussing Pinker’s argument he further attempts to elucidate the ways in which the modifications of public and inter-subjectively accessible aspects of the use of language reflect the differences in interpretations of an ambiguity. His exploration of the argument against ‘semantics of truth-conditions’ then aims to explain, contra Parsons, the sense in which talk about the truth conditions for ambiguity does not implicate a threat to Davidson’s perspective on the theory of meaning. Finally, the author argues for the view of ambiguity as a kind of ignorance/undecidability that, as he contends, represents both more realistic and more plausible theoretical option than the one on which both Pinker and Parsons found their arguments and which also comes out in Aristotle, K. Bach and W. Lycan. (shrink)

This book investigates the argument from queerness against moral realism, famously put forward by J. L. Mackie in Ethics: Inventing Right and Wrong (1977). The book can be divided into two parts. The first part, roughly comprising chapters 1 and 2, gives a critical overview of Mackie’s metaethics. In chapter 1 it is suggested that the argument from queerness is the only argument that poses a serious threat to moral realism. A partial defense of this idea is offered (...) in chapter 2 via a discussion of Mackie’s argument from relativity, which is concluded to fail for reasons that generalize to other influential arguments against moral realism. Chapter 2 also explores Mackie’s moral semantics at length. The key notion of authoritative prescriptivity is analyzed, and a new interpretation of Mackie’s error theory is defended. In the second part, consisting roughly of chapters 3 and 4, the argument from queerness is taken apart and put back together, resulting in several different versions. Chapter 3 discusses three different supervenience-related arguments, all of which are found to be unpersuasive. Chapter 4 develops two different versions of the core argument from queerness, focusing on authoritative prescriptivity. A total of thirteen objections are discussed and rejected. It is concluded that the two arguments do indeed refute the targeted versions of moral realism. Finally, in chapter 5 the entire discussion is briefly summarized. (shrink)

Recent work has demonstrated that academic research faces serious challenges. Incentives to defend publishable ideas often lead researchers astray. Despite their tendency to produce error, efforts to publish erroneous results typically help a researcher's career. In addition, errors often arise from seemingly innocent methodological assumptions that allow researchers to believe their research is sound. This article discusses this research, as well as research into difficulties facing epistemic rationality caused by nonepistemic incentives. It then applies the lessons of this (...) research to philosophical practice. It explains why philosophy likely suffers from these problems. It then provides an example of a widely shared methodological assumption that allows such research to be pursued and regularly published. It claims that the significance philosophers place on arguments is inappropriate, and that typical evaluations of philosophical arguments involve an instance of the base-rate fallacy. It concludes by discussing whether or not this article is self-defeating. (shrink)

According to moral error theory, there are no ethical facts. Error theorists often defend this view with the metaphysical argument from queerness. This argument purports to show that it is most reasonable to believe that ethical facts do not exist, because such facts are metaphysically queer and explanatorily redundant. This paper argues that even if we assume that ethical facts are metaphysically queer and explanatorily redundant, the argument from queerness does not warrant the rejection of ethical (...) facts. It only shows that it is most reasonable to refrain from believing that ethical facts exist. The argument from queerness therefore merely supports metaethical scepticism: that is, it merely supports agnosticism about the existence of ethical facts. This is cause for optimism, because metaethical scepticism is less of a threat to our moral practice than moral error theory. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Cognitive Error and Contemplative Practices:The Cultivation of Discernment in Mind and HeartWesley J. WildmanBrains are amazing organs in all creatures with central nervous systems and especially in human beings. But they are not perfect. Without forgetting the larger success story of cognitive evolution, I want to explore the way that cognitive biases sometimes produce errors in both religious and secular social settings and how such errors can be (...) diagnosed and corrected when they occur. This will involve noticing that error diagnosis and correction is a process that certain social groups have a vested interest in resisting or neglecting, in some respects, while the very same social groups may furnish resources that support the detection of cognitive errors, in other respects.This presents a moral quandary for both secular and religious groups. Should we educate children to be fully aware of their cognitive vulnerability to advertising, thereby learning how to resist and eventually become immune to one of the fundamental power sources of modern market economies? Should religious groups explain to young people their cognitive tendencies to posit the action of supernatural beings whether or not any such action exists, even though this may disrupt the power of religious groups to forge bracing social togetherness that supports psychologically useful coping skills? While I do not seek to answer such complex moral questions in this paper, I do argue that knowledge of cognitive biases and the resulting tendencies to cognitive error, self-defeating behaviors, and self-deception should be made available to those individuals and groups who are interested in promoting a high degree of critical self-awareness in the analysis of beliefs and behaviors in both secular and religious contexts.The term "error" is a potentially problematic one in that it misleadingly suggests that there might be a uniquely correct way in which cognition should work. I do not wish to suggest such a binary opposition. After all, biases exist in the human cognitive system either because they have been selected in the evolutionary process for their survival benefits or because they are side effects of other traits selected for their usefulness. My concern is with the wondrous human discovery that we can analyze [End Page 61] our behaviors and beliefs with such precision that we can sometimes detect when our cognitive biases produce mistaken beliefs and self-defeating behaviors. This forms the basis for my contention that cognition can often work better than it does—more accurately, less self-destructively—when tendencies to cognitive error are diagnosed, corrected, and perhaps even systematically resisted.The profound irony here is that the very same social groups (secular and religious) with an obvious vested interest in resisting such enlightenment in some respects can also promote processes of discernment and insight in other respects. Existing literature in the cognitive psychology of religion rarely bothers with such subtleties. It is common to assume that simply to notice the operation of cognitive biases in religion—say, in supporting belief in supernatural entities who providentially interact in human affairs, or in establishing and reinforcing people's willingness to defer to certain kinds of religious authority—is at the same time to establish the presence of rampant cognitive error, massive resistance to diagnosing and correcting it, and thus the infliction of pernicious cruelties on young children who have no way of escaping the resulting irrational indoctrination.This moral reflex to condemn religious groups because of their characteristic reluctance to acknowledge the role of cognitive biases in their beliefs and practices is understandable given the irrationality, ignorance, or denial that such reluctance suggests. I frankly acknowledge that I share this moral concern. But the actual complexities of religious practice demonstrate that the situation demands a subtler evaluation. Resistance to awareness of cognitive biases exists both inside and outside religious groups; economic and political practices in all eras and of all types have every bit as much to gain from neglecting to enlighten people about their cognitive operations as religious groups do—just consider the techniques employed in commercial advertising and political campaigns. Moreover, religious groups also promote methods of discernment and self-awareness that have historically been, and continue to be, the dominant method by which... (shrink)

Recent discussion of the problem of evil has centered around what is known as the probabilistic or evidential argument from evil. According to this argument the evil in our world is evidence against the existence of God, even though evil is logically consistent with God’s existing. Based on this it is claimed it is irrational to believe one of the traditional theistic religions, unless there is overwhelming positive evidence to counter this negative evidence. One of the most important and (...) widely discussed versions of this argument is due to Paul Draper.1 In this paper I will look at Draper’s argument and argue that he has made a simple fundamental error; as a result his argument is irrelevant to most theists. After discussing this error in Draper’s argument, I will discuss probabilistic arguments from evil from the perspective of confirmation theory. The error in Draper’s argument is easily made and could occur in any probabilistic argument from evil; looking at confirmation theory and probabilistic arguments from evil will provide insight into reasoning about evil and belief in God.

Error theorists about color argue that our ordinary judgments ascribing color to material objects are all false. The error theorist proposes that everything that is so, including the fact that material objects appear to us to have color, can best be explained without ever attributing color to objects (for instance, by appealing to surface reflectance properties, the nature of light, the neurophysiology of perceivers, etc.). The appeal of this view stems in significant part from the prevalent thought (...) that such explanations are strongly suggested by our present scientific conception of the world. Recently, however, Barry Stroud has argued that error theorists cannot successfully even acknowledge, let alone explain, all of the facts that error theorists must acknowledge. In this paper, I shall raise an objection to Stroud's argument. I shall conclude by mentioning one way in which we might develop Stroud's general strategy with more success. (shrink)

Moral judgments attempt to describe a reality that does not exist, so they are all false. This troubling view is known as the moral error theory. Christopher Cowie defends it against the most compelling counter-argument, the argument from analogy: Cowie shows that moral error theory does not compromise the practice of making epistemic judgments.

It is often said that our moral experience, broadly construed to include our ways of thinking and talking about morality, has a certain objective-seeming character to it, and that this supports a presumption in favor of objectivist theories and against anti-objectivist theories like Mackie’s error theory. In this paper, I argue that our experience of morality does not support objectivist moral theories in this way. I begin by arguing that our moral experience does not have the uniformly objective-seeming character (...) it is typically claimed to have. I go on to argue that even if moral experience were to presuppose or display morality as a realm of fact, we would still need a reason for taking that to support theories according to which it is such a realm. I consider what I take to be the four most promising ways of attempting to supply such a reason: inference to the best explanation, epistemic conservatism, the Principle of Credulity, and the method of wide reflective equilibrium. In each case, I argue, the strategy in question does not support a presumption in favor of objectivist moral theories. (shrink)

In the years 1675-84, Leibniz sought to disprove Descartes’s account of clear and distinct perception by implementing a three-step argumentative strategy. The first part of the paper reconstructs the argument and highlights what aspects of Descartes’s epistemology it addresses. The reconstruction shows that the argument is based on conceivability errors. These are a kind of symbolic cognition that prove Descartes’s clear and distinct perception as introspectively indistinguishable from Leibniz’s symbolic cognition. The second part of the paper explores the epistemic (...) implication of the indistinguishability between clear and distinct perception and symbolic cognition: the mind constitutively depends on products of the imagination. My conclusion addresses the role of the imagination in symbolization. Symbolization does not exceed imagination; it rather is an idealized use of cognitive surrogates, like characters, to submit to the imagination what is not subject to it. (shrink)

Almost all evangelical Christians believe that the writing of the Bible was divinely inspired and represents God's main revelation to humanity. They also believe that the Bible contains special features which constitute evidence of its divine inspiration. This would be a use of the Bible to prove God's existence within natural theology rather than within revealed theology, since the book's features are supposed to be evident even to (open-minded) skeptics. Furthermore, since a divinely inspired work must be true, those features (...) are thereby also evidence of the Bible's truth, and thus can be used in support of Christianity as the one true religion. When expressed that way, the reasoning can be construed as an argument both for God's existence and for the truth of the gospel message from the alleged special features of the Bible. We may refer to it as "the Argument from the Bible". Although almost all evangelical Christians agree with it at least to some extent, it is an argument that is for the most part ignored by professional philosophers of religion. One explanation for such neglect is that the argument can be easily refuted. In this essay/outline, I sketch how such a refutation might be formulated. (shrink)

Arguments from disagreement against moral realism begin by calling attention to widespread, fundamental moral disagreement among a certain group of people. Then, some skeptical or anti-realist-friendly conclusion is drawn. Chapter 2 proposes that arguments from disagreement share a structure that makes them vulnerable to a single, powerful objection: they self-undermine. For each formulation of the argument from disagreement, at least one of its premises casts doubt either on itself or on one of the other premises. (...) On reflection, this shouldn’t be surprising. These arguments are intended to support very strong metaphysical or epistemological conclusions about morality. They must therefore employ very strong metaphysical or epistemological premises. But, given the pervasiveness of disagreement in philosophy, especially about metaphysics and epistemology, very strong premises are virtually certain to be the subject of widespread, intractable disagreement—precisely the sort of disagreement that proponents of these arguments think undermine moral claims. Thus, these arguments undermine their own premises. If Chapter 2’s argument is sound, it provides realists with a single, unified strategy for responding to any existing or forthcoming arguments from disagreement. (shrink)

In chapter 5 of Knowledge and its Limits, T. Williamson formulates an argument against the principle (KK) of epistemic transparency, or luminosity of knowledge, namely “that if one knows something, then one knows that one knows it”. Williamson’s argument proceeds by reductio: from the description of a situation of approximate knowledge, he shows that a contradiction can be derived on the basis of principle (KK) and additional epistemic principles that he claims are better grounded. One of them is a (...) reflective form of the margin for error principle defended by Williamson in his account of knowledge. We argue that Williamson’s reductio rests on the inappropriate identification of distinct forms of knowledge. More specifically, an important distinction between perceptual knowledge and non-perceptual knowledge is wanting in his statement and analysis of the puzzle. We present an alternative account of this puzzle, based on a modular conception of knowledge: the (KK) principle and the margin for error principle can coexist, provided their domain of application is referred to the right sort of knowledge.

I will put forward a short, simple argument for a pair of realist claims: metaphysical realism and what I will refer to as epistemological realism. The argument will rely upon nothing more than our apparent memories. Having presented the argument, I will go on to consider possible objections to it, of which there will be a number but none of which will do more than complicate the matter. The argument I present borrows from Peirce’s view that the world’s capacity (...) to surprise us plays a vital role in guiding us toward truth, and from the argument to the best explanation. However, it combines the two views in a way I have not seen done previously. (shrink)
