Existing analyses of disinformation tend to embrace the view that disinformation is intended or otherwise functions to mislead its audience, that is, to produce false beliefs. I argue that this view is doubly mistaken. First, while paradigmatic disinformation campaigns aim to produce false beliefs in an audience, disinformation may in some cases be intended only to prevent its audience from forming true beliefs. Second, purveyors of disinformation need not intend to have any effect at all on their audience’s beliefs, aiming (...) instead to manipulate an audience’s behavior through alteration of sub-doxastic states. Ultimately, I argue that attention to such non-paradigmatic forms of disinformation is essential to understanding the threat disinformation poses and why this threat is so difficult to counter.

Deepfakes pose a multi-faceted threat to the acquisition of knowledge. It is widely hoped that technological solutions—in the form of artificially intelligent systems for detecting deepfakes—will help to address this threat. I argue that the prospects for purely technological solutions to the problem of deepfakes are dim. Especially given the evolving nature of the threat, technological solutions cannot be expected to prevent deception at the hands of deepfakes, or to preserve the authority of video footage. Moreover, the success of such (...) technologies depends on institutional trust that is in short supply. Finally, outsourcing the discrimination between the real and the fake to automated, largely opaque systems runs the risk of undermining epistemic autonomy. (shrink)

Philosophers who study conspiracy theories have increasingly addressed the questions of where conspiracy theories come from, what such theories do, and what to do about them. This essay serves as a commentary on the answers to these questions offered by contributors to this special issue.

Deepfakes and other forms of synthetic media are widely regarded as serious threats to our knowledge of the world. Various technological responses to these threats have been proposed. The reactive approach proposes to use artificial intelligence to identify synthetic media. The proactive approach proposes to use blockchain and related technologies to create immutable records of verified media content. I argue that both approaches, but especially the reactive approach, are vulnerable to a problem analogous to the ancient problem of the criterion—a (...) line of argument with skeptical implications. I argue that, while the proactive approach is relatively resistant to this objection, it faces its own serious challenges. In short, the proactive approach would place a heavy burden on users to verify their own content, a burden that is exacerbated by and is likely to exacerbate existing inequalities. (shrink)

Quassim Cassam has argued that psychological and epistemological analyses of conspiracy theories threaten to overlook the political nature of such theories. According to Cassam, conspiracy theories are a form of political propaganda. I develop a limited critique of Cassam's analysis.This paper advances two core theses. First, acceptance of conspiracy theories requires a rejection of epistemic authority that renders conspiracy theorists susceptible to co-option by certain political programs while insulating such programs from criticism. I argue that the contrarian nature of conspiracy (...) theories partially accounts for the prominence of such theories in populist movements.Second, the contrarian nature of conspiracy theories partially accounts for their attractiveness, especially among those to whom populism already appeals. I argue that for those who resent what appears from their perspective as the shaping of the epistemic landscape by alien perspectives, conspiracy theorizing may facilitate the reassertion of epistemic autonomy.

This paper discusses the provocative views of Skene and Parker as to the role of religious or other ideologically based interest groups in law and policy making. We draw distinctions between doctrine and prejudice and between argument and ideology which we trust take the debate further. Finally we recommend an ethereal, democratic, and populist partial solution.

This book argues that misinformation poses a multi-faceted threat to knowledge, while arguing that some forms of content moderation risk exacerbating these threats. It proposes alternative forms of content moderation that aim to address this complexity while enhancing human epistemic agency. The proliferation of fake news, false conspiracy theories, and other forms of misinformation on the internet and especially social media is widely recognized as a threat to individual knowledge and, consequently, to collective deliberation and democracy itself. This book argues (...) that misinformation presents a three-pronged threat to knowledge. While researchers often focus on the role of misinformation in causing false beliefs, this deceptive potential of misinformation exists alongside the potential to suppress trust and to distort the perception of evidence. Recognizing the multi-faceted nature of this threat is essential to the development of effective measures to mitigate the harms associated with misinformation. The book weaves together work in analytic epistemology with emerging empirical work in other disciplines to offer novel insights into the threats posed by misinformation. Additionally, it breaks new ground by systematically assessing different forms of content moderation from the perspective of epistemology. Misinformation, Content Moderation, and Epistemology will appeal to philosophers working in applied and social epistemology, as well as scholars and advanced students in disciplines such as communication studies, political science, and social psychology who are researching misinformation.

Particularists maintain that conspiracy theories are to be assessed individually, while generalists hold that conspiracy theories may be assessed as a class. This paper seeks to clarify the nature and importance of the debate between particularism and generalism, while offering an argument for a version of generalism. I begin by considering three approaches to the definition of conspiracy theory, and offer reason to prefer an approach that defines conspiracy theories in opposition to the claims of epistemic authorities. I argue that (...) particularists rely on an untenably broad definition of conspiracy theory. Then, I argue that particularism and its counterpart are best understood as constellations of theses, rather than a pair of incompatible theses. While some particularist theses are highly plausible, I argue that one important particularist thesis is false. The argument for this conclusion draws on the history of false conspiracy theories. I then defend this conclusion against a pair of potential objections. (shrink)

This paper describes the ways in which trolls and bots impede the acquisition of knowledge online. I distinguish between three ways in which trolls and bots can impede knowledge acquisition, namely, by deceiving, by encouraging misplaced skepticism, and by interfering with the acquisition of warrant concerning persons and content encountered online. I argue that these threats are difficult to resist simultaneously. I argue, further, that the threat that trolls and bots pose to knowledge acquisition goes beyond the mere threat of (...) online misinformation, or the more familiar threat posed by liars offline. Trolls and bots are, in effect, fake persons. Consequently, trolls and bots can systemically interfere with knowledge acquisition by manipulating the signals whereby individuals acquire knowledge from one another online. I conclude with a brief discussion of some possible remedies for the problem of fake persons. (shrink)

Brought together by an impressive, international array of contributors this book presents a representative study of some of the many misinterpretations that have evolved concerning the medieval period.

"This book re-examines the old debate about the relationship between rationality and literacy. Does writing 'restructure consciousness'? Do preliterate societies have a different 'mind-set' from literate societies? Is reason 'built in' to the way we think? How is literacy related to numeracy? Is the 'logical form' that Western philosophers recognize anything more than an extrapolation from the structure of the written sentence? Is logic, as developed formally in Western education, intrinsically beyond the reach of the preliterate mind? What light, if (...) any, do the findings of contemporary neuroscience throw on such issues? Roy Harris challenges the received mainstream opinion that reason is an intrinsic property of the human mind, and argues that the whole Western conception of rational thought, from Classical Greece down to modern symbolic logic, is a by-product of the way literacy developed in European cultures." --publisher's website.

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)

Who deserves credit for epistemic successes, and who is to blame for epistemic failures? Extreme views, which would place responsibility either solely on the individual or solely on the individual’s surrounding environment, are not plausible. Recently, progress has been made toward articulating virtue epistemology as a suitable middle ground. A socio-environmentally oriented virtue epistemology can recognize that an individual’s traits play an important role in shaping what that individual believes, while also recognizing that some of the most efficacious individual traits (...) have to do with how individuals structure their epistemic environments and how they respond to information received within these environments. I contribute to the development of such an epistemology by introducing and elucidating the virtue of epistemic exactingness, which is characterized by a motivation to regulate the epistemically significant conduct of others.

Some philosophers regard it as a serious possibility that we now exist within a simulation. That this hypothesis is somewhat probable has been defended extensively by Nick Bostrom. Notably, Bostrom does not defend the conclusion that we inhabit a simulation, but rather the disjunctive conclusion that the human species is very likely to die out before reaching a ‘posthuman stage’, that posthuman civilizations are extremely unlikely to run significant numbers of simulations, or that we almost certainly inhabit a simulation. Bostrom (...) argues that there is no basis for strongly favouring one of these alternatives over its counterparts. The upshot is that it is fairly probable that we inhabit a simulation. I argue that posthuman civilizations are likely to be unwilling to run significant numbers of simulations, thereby undermining the case for assigning a somewhat high probability to the hypothesis that we live in a simulation.

Santideva's 8th century Mahayana Buddhist classic, the Guide to the Practices of Awakening (Bodhicaryavatara), has been a source of philosophical inspiration in the Indian and Tibetan traditions for over a thousand years. Stephen Harris guides us through a philosophical exploration of Santideva's masterpiece, introducing us to his understanding of the compassionate bodhisattva, who vows to liberate the entire universe from suffering. Individual chapters provide studies of the bodhisattva virtues of generosity, patience, compassion, and wisdom, illustrating the role each plays (...) in Santideva's account of well-being and moral development. Harris also provides in-depth analysis of many of Santideva's most influential arguments, demonstrating how he employs reasoning as a method to cultivate moral character. (shrink)

A retired manager and university teacher reflects on global ethics, on the purpose of life, and on the challenges facing global ethics in a contemporary world where there is no certainty about shared belief or shared values. The future lies, he concludes, with process and with a deeper understanding of one another.

Existential gratitude-gratitude for one's very existence or life as a whole-is pervasive across the most influential human, cultural and religious traditions. Weaving together analytic and continental, as well as non-western and historical philosophical perspectives, this volume explores the nexus of gratitude, existence and God as an inter-subjective phenomenon for the first time. A team of leading scholars introduce existential gratitude as a perennially and characteristically human phenomenon, central to the distinctive life of our species. Attention is given to the conditions (...) under which existence itself might be construed as having a gift-like or otherwise gratitude-inducing character. Drawing on a diversity of perspectives, chapters mark out new territory in philosophical inquiry, addressing whether and in what sense we ought to be grateful for our very existence. By analysing gratitude, this collection makes a novel contribution to the discourse on moral emotions, phenomenology, anti-natalism and theology. (shrink)

Identifying rhetorical figures with marginal to non-existent lexico-syntactic signatures poses significant challenges for computational approaches reliant upon structural definitions or descriptions. One such figure is prolepsis ([Formula: see text]ó[Formula: see text]), which this essay charts out in some detail, addressing the challenges and the benefits of rendering such figures computationally tractable through the use of argument schemes with attention to metadiscursive or macro-discursive norms offered by pragma-dialectical traditions.
