Many of our beliefs are acquired online. Online epistemic environments are replete with fake news, fake science, fake photographs and videos, and fake people in the form of trolls and social bots. The purpose of this paper is to investigate the threat that such online fakes pose to the acquisition of knowledge. I argue that fakes can interfere with one or more of the truth, belief, and warrant conditions on knowledge. I devote most of my attention to the effects of (...) online fakes on satisfaction of the warrant condition, as these have received comparatively little attention. I consider three accounts of the conditions under which fakes compromise the warrant condition. I argue for the third of these accounts, according to which the propensity of fakes to exist in an environment threatens warrant acquisition in that environment. Finally, I consider some limitations on the epistemic threat of fakes and suggest some strategies by which this threat can be mitigated. (shrink)

Mind and Supermind offers an alternative perspective on the nature of belief and the structure of the human mind. Keith Frankish argues that the folk-psychological term 'belief' refers to two distinct types of mental state, which have different properties and support different kinds of mental explanation. Building on this claim, he develops a picture of the human mind as a two-level structure, consisting of a basic mind and a supermind, and shows how the resulting account sheds light on a (...) number of puzzling phenomena and helps to vindicate folk psychology. Topics discussed include the function of conscious thought, the cognitive role of natural language, the relation between partial and flat-out belief, the possibility of active belief formation, and the nature of akrasia, self-deception and first-person authority. This book will be valuable for philosophers, psychologists and cognitive scientists. (shrink)

A central issue in epistemology concerns the connection between truth and justification. The burden of our paper is to explain this connection. Reliabilism, defended by Goldman, assumes that the connection is one of reliability. We argue that this assumption is too strong. We argue that foundational theories, such as those articulated by Pollock and Chisholm fail to elucidate the connection. We consider the potentiality of coherence theories to explain the truth connection by means of higher level convictions about probabilities, which (...) we call doxastic ascent, and defend such a theory. Our defense appeals to the work of Reid and contemporary cognitive psychology in order to account for the psychological reality of higher level evaluations. (shrink)

The best grounds for accepting contextualism concerning knowledge attributions are to be found in how knowledge-attributing (and knowledge-denying) sentences are used in ordinary, nonphilosophical talk: What ordinary speakers will count as “knowledge” in some non-philosophical contexts they will deny is such in others. Contextualists typically appeal to pairs of cases that forcefully display the variability in the epistemic standards that govern ordinary usage: A “low standards” case (henceforth, “LOW”) in which a speaker seems quite appropriately and truthfully to ascribe knowledge (...) to a subject will be paired with a “high standards” case (“HIGH”) in which another speaker in a quite different and more demanding context seems with equal propriety and truth to say that the same subject (or a similarly positioned subject) does not know. The contextualist argument based on such cases is driven by the premises that the positive attribution of knowledge in LOW is true, and that the denial of knowledge in HIGH is true. And where the contextualist has constructed HIGH and LOW wisely, those premises are in turn powerfully supported by the two mutually reinforcing strands of evidence that both of the claims intuitively seem true, and that both claims are perfectly appropriate. The resulting argument for contextualism is very powerful indeed, but I am on the offensive making that case in another paper: “The Ordinary Language Basis for Contextualism and the New Invariantism.”.

Atomism denies that complexes exist. Common-sense metaphysics may posit masses, composite individuals and sets, but atomism says there are only simples. In a singularist logic, it is difficult to make a plausible case for atomism. But we should accept plural logic, and then atomism can paraphrase away apparent reference to complexes. The paraphrases require unfamiliar plural universals, but these are of independent interest; for example, we can identify numbers and sets with plural universals. The atomist paraphrases would fail if plurals (...) presuppose complexes: but an Appendix shows that reference to complexes is not required in the semantics of plurals. (shrink)

One chapter in the science of emotion has focused, largely through an individualist lens, on just a few emotions: the Ekman Six. Considerable debate has occurred and entrenched positions have ensued. In this essay we offer evidence and argument revealing that there are not only six emotions, nor states measured as valence and arousal, but upwards of 20 discrete emotions that contribute to our subjective and social lives. These emotions enable the rich fabric of relationships, from caregiving interactions to collective (...) activities, that are vital to cooperation. Grounded in advances in cultural evolution, we detail how emotions and culture co-evolved, highlighting how emotions are building blocks of cultural forms such as ceremonies, dance, narratives, music, and visual art.

In this dissertation, I defend an answer to the following question in the diachronic personal identity debate: what are the necessary and sufficient conditions for our persistence over time? Two popular approaches to answering this question are the psychological and the somatic approach. On the former approach, we persist in virtue of some sort of psychological continuity. So, some proponents of the psychological approach think that we cease to exist if we lose certain features of our psychology such as our (...) memories, beliefs, and rationality. On the latter approach, we persist in virtue of some sort of physical continuity. Eric Olson defends a version of the somatic approach called animalism. On his view, we are numerically identical to biological organisms and we persist if and only if the organisms we are persist. Although Olson’s animalism has some benefits, it also faces some challenges. For example, many people would say that we go wherever our brains go (if we go anywhere at all) because our brains (more specifically, our cerebra) realize the aspects of our psychology traditionally associated with persons, such as memories, beliefs, rationality, and self-awareness. But on Olson’s animalism, our psychology has nothing to do with our persistence and we go wherever our bodies go rather than our cerebra. Following Aristotle and Aquinas, I lay out an animalist view of our persistence called hylomorphic animalism. On this view, we are numerically identical to rational animals, which are living bodies composed of prime matter and a rational soul. Furthermore, we persist if and only if the composite of matter and rational soul persists. I claim that hylomorphic animalism makes better sense of certain contemporary personal identity thought experiments than Olson’s animalism. For example, contra Olson, I argue that our psychology does have something to do with our persistence and that we go wherever our brains go. (shrink)

The efforts of some institutional review boards (IRBs) to exercise what is viewed as appropriate oversight may contribute to deceit on the part of investigators who feel unjustly treated. An organizational justice paradigm provides a useful context for exploring why certain IRB behaviors may lead investigators to believe that they have not received fair treatment. These feelings may, in turn, lead to intentional deception by investigators that IRBs will rarely detect. Paradoxically, excessive protective zeal by IRBs may actually encourage misconduct (...) by some investigators. The authors contend that, by fostering a climate in which investigators perceive that they receive fair and unbiased treatment, IRBs optimize the likelihood of collegial compliance with appropriate participant protections.

exactly as the essay appears in Skepticism. It's pretty close, though. In the version that appears in the book, page references to other essays in Skepticism refer to page numbers in the book, while below page references are, for the most part, to the original place of publication of the essays referred to. Also, I below make one correction (in red) of a factual error..

How did the French Revolution become thinkable? Keith Michael Baker, a leading authority on the ideological origins of the French Revolution, explores this question in his wide-ranging collection of essays. Analyzing the new politics of contestation that transformed the traditional political culture of the Old Regime during its last decades, Baker revises our historical map of the political space in which the French Revolution took form. Some essays study the ways in which the revolutionaries' break with the past was (...) prepared by competition between agents and critics of absolute monarchy to control the cultural resources and political meanings of French sought before 1789 to reconstitute their body politic; and by the invention of 'public opinion' as a new form of political authority displacing notions of 'representation', 'constitution', 'sovereignty' - and of 'the French Revolution' itself - the ambiguities, tensions, and contradictions that were to drive the revolutionary dynamic in subsequent years. The result is a substantial and unified set of studies, stimulating renewed reflection on one of the central themes in modern European history. (shrink)

The concept of the 'social Trinity', which posits three conscious subjects in God, radically revised the traditional Christian idea of the Creator. It promoted a view of God as a passionate, creative and responsive source of all being. Keith Ward argues that social Trinitarian thinking threatens the unity of God, however, and that this new view of God does not require a 'social' component. Expanding on the work of theologians such as Barth and Rahner, who insisted that there was (...) only one mind of God, Ward offers a coherent, wholly monotheistic interpretation of the Trinity. Christ and the Cosmos analyses theistic belief in a scientific context, demonstrating the necessity of cosmology to theological thinking that is often overly myopic and anthropomorphic. This important volume will benefit those who seek to understand what the Trinity is, why it matters and how it fits into a scientific account of the universe. (shrink)

Luck egalitarians claim that disadvantage is worse when it emerges from an unchosen risk than when it emerges from a chosen risk. I argue that disadvantage is also worse when it emerges from an unchosen risk that the disadvantaged agent would have declined to take, had he or she been able to do so, than when it emerges from an unchosen risk that the disadvantaged agent would not have declined to take. Such a view is significant because it allows both (...) luck egalitarians and prioritarians to respond to Voorhoeve and Fleurbaey's charge that they fail to accommodate intuitions about the moral relevance of interpersonal boundaries – the so-called separateness of persons objection. I argue that the view is plausible independently of its ability to answer the separateness of persons objection, and is a natural extension of the luck egalitarian concern with the impact of unchosen circumstance.

This paper rejects a traditional epistemic interpretation of conditional probability. Suppose some chance process produces outcomes X, Y,..., with probabilities P(X), P(Y),... If later observation reveals that outcome Y has in fact been achieved, then the probability of outcome X cannot normally be revised to P(X|Y) ['P&Y)/P(Y)]. This can only be done in exceptional circumstances - when more than just knowledge of Y-ness has been attained. The primary reason for this is that the weight of a piece of evidence varies (...) with the means by which it is provided, so knowledge of Y-ness does not have uniform impact on the probability of X. A better updating of the probability of X is provided by P(X|Y*), where Y* is not an outcome of the chance process being observed, but the sentence 'the outcome Y has been observed', an 'outcome' of the subsequent observation process. This alternative formula is widely endorsed in practice, but not well recognized in theory, where the oversight has generated some unsatisfactory consequences. (shrink)

As a result of in-house discussions stimulated by previous Gonzaga engineering ethics conferences, Coffman Engineers began the implementation of what is to be a company-wide ethics training program. While preparing a curriculum aimed at consulting engineers, we found very little guidance as to how to proceed with most available literature being oriented towards the academic environment. We consulted a number of resources that address the teaching of engineering ethics in higher education, but questioned their applicability for the Consulting Engineering environment. (...) This lack of guidance led us to informal research into the ethical knowledge and attitudes of both consulting engineers and engineering students. Some of our findings were unexpected, and suggest that a simpler approach to teaching ethics to working professionals might be preferred to that typically promoted in higher education. (shrink)

At 14 months, children appear to struggle to apply their fairly well-developed speech perception abilities to learning similar sounding words (e.g., bih/dih; Stager & Werker, 1997). However, variability in nonphonetic aspects of the training stimuli seems to aid word learning at this age. Extant theories of early word learning cannot account for this benefit of variability. We offer a simple explanation for this range of effects based on associative learning. Simulations suggest that if infants encode both noncontrastive information (e.g., cues (...) to speaker voice) and meaningful linguistic cues (e.g., place of articulation or voicing), then associative learning mechanisms predict these variability effects in early word learning. Crucially, this means that despite the importance of task variables in predicting performance, this body of work shows that phonological categories are still developing at this age, and that the structure of noninformative cues has critical influences on word learning abilities.

Some texts appear more than once across the corpus of Zygmunt Bauman’s work. This has led to accusations of self-plagiarism and a lack of scholarly rigour. This paper is an explanation of why texts reappear. It pays attention to a number of frequently overlooked texts from the 1970s which are of fundamental importance for any understanding of Bauman’s work. It is contended that if: (a) there is an understanding of the stakes and purpose of sociology as it is framed in (...) Bauman’s work; and (b) attention is paid to the argument of Hermeneutics and Social Science; then (c) the repetition of texts across the work becomes explicable and unproblematic. The paper argues that dealings with Bauman’s work need to be more aware of the less well-known texts. They also need to be alert to different – and incommensurable – ways of practising sociology.

We did not, as Brakel & Shevrin imply, intend to classify either System 1 or System 2 as rational or irrational. Instrumental rationality is assessed at the organismic level, not at the subpersonal level. Thus, neither System 1 nor System 2 are themselves inherently rational or irrational. Also, that genetic fitness and instrumental rationality are not to be equated was a major theme in our target article. We disagree with Bringsjord & Yang's point that the tasks used in the heuristics (...) and biases literature are easy. Bringsjord & Yang too readily conflate the ability to utilize a principle of rational choice with the disposition to do so. Thus, they undervalue tasks in the cognitive science literature that compellingly reveal difficulties with the latter. We agree with Newton & Roberts that models at the algorithmic level of analysis are crucial, but we disagree with their implication that attention to issues of rationality at the intentional level of analysis impedes work at the algorithmic level of analysis.

This article seeks to explore some of the origins of Zygmunt Bauman's social thought. Using the metaphor of paths from a story by Borges, the article argues that Bauman's work follows paths which were opened up to him by Gramsci, Camus and Levinas. Bauman has acknowledged the importance of Gramsci and Levinas in his intellectual development and, therefore, the identification of a path leading from Camus is offered by way of circumstantial rather than direct evidence. The article discusses each of (...) these thinkers in the context of Bauman's own themes and concerns and, in so doing, it is hoped to show that Bauman's work has long been marked by a consistence of ambition and foundational assumptions.

Autoantibodies to three eukaryotic 60S ribosomal phosphoproteins P0, P1 and P2 have been found in the sera of 10–20% of patients with systemic lupus erythematosus (SLE). These three proteins share a common epitope contained within the carboxy terminal 22 amino acids of each protein. Because central nervous system disturbances, with major behavioural disorders, occur in a significant fraction of SLE patients, the antiribosomal autoantibodies were measured in this subset of SLE individuals to determine whether or not there was an association. (...) This antibody is present in 90% of SLE patients who were diagnosed as having psychosis, secondary to the disease. (shrink)

This essay investigates questions about the relationship between language, speech, and democratic institutions by bringing into conversation Hannah Arendt's and Pierre Bourdieu's distinctive views of the politics of language and speech. First, I explicate Arendt's account of the connection between speech, action, and identity disclosure, as well as its role in her broad conception of political institutions. Next, I complicate this outlook by examining Bourdieu's political sociology of language, focusing on the ways that linguistic competences valorized in particular institutional settings (...) operate as mechanisms of silencing, domination, and exclusion. Finally, I bring these approaches together by investigating political events—AIDS activism in the United States during the 1980s and early 1990s—that raise critical issues regarding the politics of language and speech within a specific institutional setting. By reading Arendt and Bourdieu together in the context of these events, one can develop a defensible account of the politics of speech in democratic theory and practice. (shrink)

There are those philosophers and historians of science who claim that the acceptance and rejection of scientific theories is underdetermined by experimental results. They conclude that there is no rational method for deciding such matters solely on the basis of empirical information. The acceptance and rejection of scientific theories depends on social influence and is settled by social dominance. This I call the dominance thesis. There are also those who hold, on the contrary, that the acceptance and rejection of theories (...) in science is based solely on empirical information according to a rational method. They conclude that the acceptance and rejection of scientific theories is fully determined by experimental results. This I call the experimentalism thesis. The dominance thesis and the experimentalism thesis are both false. Both share a common premise, to wit, that empirical information is limited to experimental results. There is, however, another source of empirical information, the opinions of experts. When such social information is properly aggregated, the acceptance and rejection of scientific theories, though underdetermined by experimental results, is fully determined by the total information available.

In most logical systems, inferences cannot be invalidated simply by the addition of new premises. If an inference can be drawn from a set of premises S, then it can also be drawn from any larger set incorporrating S. The truth of the original premises guarantees the truth of the inferred conclusion, and the addition of extra premises cannot undermine it. This property is known as monotonicity. Nonmonotonic inference lacks this property. The conclusions drawn are provisional, and new information may (...) lead to the withdrawal of a previous conclusion, even though none of the original premises is retracted. (shrink)

Weighted averaging is a method for aggregating the totality of information, both regimented and unregimented, possessed by an individual or group of individuals. The application of such a method may be warranted by a theorem of the calculus of probability, simple conditionalization, or Jeffrey's formula for probability kinematics, all of which average in terms of the prior probability of evidence statements. Weighted averaging may, however, be applied as a method of rational aggregation of the probabilities of diverse perspectives or persons (...) in cases in which the weights cannot be articulated as the prior probabilities of statements of evidence. The method is justified by Wagner's Theorem exhibiting that any method satisfying the conditions of the Irrelevance of Alternatives and Zero Unanimity must, when applied to three or more alternatives, be weighted averaging.

This paper argues against a standard view that all deterministic and conservative classical mechanical systems are time-reversible, by asking how the temporal evolution of a system modulates parametric imprecision (either ontological or epistemic). It notes that well-behaved systems (e.g. inertial motion) can possess a dynamics which is unstable enough to fail at reversing uncertainties—even though exact values are reliably reversed. A limited (but significant) source of irreversibility is thus displayed in classical mechanics, closely analogous the lack of predictability revealed by (...) unstable chaotic systems. (shrink)

In the history of thermodynamics, two dates stand out as especially important: 1824, when Sadi Carnot's brilliant memoirRéflexions sur la puissance motrice du feuappeared in print; and 1850, when Rudolf Clausius published his similarly titled paper ‘Ueber die bewegende Kraft der Wärme’. In this paper Clausius narrowly beat the Scottish physicist William Thomson to the solution of a puzzle which had been highlighted in the latter's recent publications: how could Carnot's theory, with all its intellectual attractions, be reconciled with the (...) newly discovered principle of the inter-convertibility of heat and work? Clausius's solution (as is well known) was to replace Carnot's axiom of heat conservation, with the axiom now known as the second law of thermodynamics. (shrink)
