This volume has its roots in two recent developments within mainstream analytic epistemology: a growing recognition over the past two or three decades of the active and social nature of our epistemic lives; and, more recently still, the increasing appreciation of the various ways in which the epistemic practices of individuals and societies can, and often do, go wrong. The theoretical analysis of these breakdowns in epistemic practice, along with the various harms and wrongs that follow as a consequence, constitutes (...) an approach to epistemology that we refer to as non-ideal epistemology. In this introductory chapter we introduce and contextualise the ten essays that comprise this volume, situating them within four broad sub-fields: vice epistemology, epistemic injustice, inter-personal epistemic practices, and applied epistemology. We also provide a brief overview of several other important growth areas in non-ideal epistemology. (shrink)

Sometimes we disagree because of fundamental differences in what we treat as reasons for belief. Such are ‘deep disagreements'. Amongst the questions we might ask about deep disagreement is the epistemic normative one: how ought one to respond to disagreement, when that disagreement is deep. This paper addresses that question. According to the position developed, how one ought to respond to deep disagreement depends upon two things: (i) Whether one remains, in the context of disagreement, permitted to trust oneself in (...) following one's epistemic norms and in relation to that (ii) whether one has the shared stock of social-epistemic experiences with followers of one's rival's norms such that one could reasonably be expected to see their way of doing things as a genuine epistemic alternative to one's own. Section 1 introduces a model of deep disagreement such that deep disagreements occur when disputants disagree because they follow different epistemic norms. Section 2 surveys the possible theoretical stances to take towards the epistemic-normative question. Section 3 develops an account of what it is to follow an epistemic norm. Section 4 applies this conception of norm-following to the epistemic-normative question. Section 5 discusses two points of clarification. (shrink)

How we engage in epistemic practice, including our methods of knowledge acquisition and transmission, the personal traits that help or hinder these activities, and the social institutions that facilitate or impede them, is of central importance to our lives as individuals and as participants in social and political activities. Traditionally, Anglophone epistemology has tended to neglect the various ways in which these practices go wrong, and the epistemic, moral, and political harms and wrongs that follow. In the past decade, however, (...) there has been a turn towards the non-ideal in epistemology. This volume gathers new works by emerging and world-leading scholars on a significant cross section of themes in non-ideal epistemology. Articles focus on topics including intellectual vices, epistemic injustices, interpersonal epistemic practices, and applied epistemology. In addition to exploring the various ways in which epistemic practices go wrong at the level of both individual agents and social structures, the papers gathered herein discuss how these problems are related, and how they may be addressed. -/- Contributors: Alison Bailey, Olivia Bailey, Simon Barker, Heather Battaly, Havi Carel, Quassim Cassam, Charlie Crerar, Miranda Fricker, Trystan S.

This paper discusses the normative structure of principles that require belief-revision in the face of disagreement, the role of self-trust in our epistemic lives, and the tensions that arise between the two. Section 2 argues that revisionary principles of disagreement share a general normative structure such that they prohibit continued reliance upon the practices via which one came to hold the beliefs under dispute. Section 3 describes an affective mode of epistemic self-trust that can be characterised as one’s having an (...) attitude of optimism about the reliability of the practices via which one forms beliefs. The availability of affective self-trust is crucial to being able to rationally resist doubts about those practices. However, as argued in the final section of the paper, following revisionary principles of disagreement can render such trust psychologically unavailable. Consequently, attempts to follow such principles can have doxastic consequences that predictably exceed their normative implications. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The End of Argument: Knowledge and the InternetSimon Barker1. Fermat's last videoModern mathematics is nearly characterized by the use of rigorous proofs. This practice, the result of literally thousands of years of refinement, has brought to mathematics a clarity and reliability unmatched by any other science.(Jaffe and Quinn 1993, 1)The above passage illustrates how mathematicians have come to esteem rigorous argument as the most important feature of their subject. (...) In turn, the example of mathematics has, over a long period, made rigorous argument an ideal in many other areas of inquiry—from the sciences to theology. How interesting it is, then, that some mathematicians have begun to question that ideal. Gian-Carlo Rota, for example, has said that the axiomatic method of presentation in mathematics has now reached "the zenith of fanaticism" and that the identification of mathematics with this method "is having a corrosive effect on the way mathematics is viewed by scientists in other disciplines" (1997, 189). William Thurston has blamed the formality of contemporary mathematics for "the whole system of generally poor communication" within the subject. According to Thurston, ordinary conversation between mathematicians can often convey a new solution in a matter of minutes, whereas a formal proof delivered in a seminar will take an hour, and a written article may take several hours or even days to understand. In Thurston's view, this disparity arises precisely because conversationalists go far beyond formal mathematical language:They use gestures, they draw pictures and diagrams, they make sound effects and use body language. Communication is more likely to be two-way, so that people can concentrate on what needs the most attention. With these channels of communication, they are in a much better position to convey what's going on, not just in their logical and linguistic facilities, but in their other mental facilities as well. [End Page 154](Thurston 1994, 166)Sadly, however, mathematicians can only converse like this in private. To reach the rest of their audience, they have to publish in journals. Journal articles are limited to formal language and so must convey results more slowly. Formality, though less efficient, is more publishable.Yet there is hope. Another mathematician, Andrew Odlyzko, has suggested that the unfortunate limitations of printed journals can now be overcome with computers. Computers can allow mathematicians to distribute something more than the traditional style of printed proof. Odlyzko suggests an electronic scrapbook that would include a video of each author lecturing about their results (Odlyzko 1995, 90-91). Fermat's Last Video? The point is that if these suggestions come to pass, publication of mathematical results will no longer involve stripping away informal features and replacing them with formal language, as if rigorous argument was all that mattered. Instead, the informal features that help mathematicians to understand new results so quickly in ordinary conversation will be given equal air time. The ideal, for publication at least, will be less formal.Is this just a gimmick? Is it something that will go away, if we shut our eyes, leaving the centuries old ideal of formal proof intact? What I wish to discuss here are some of the reasons why mathematics, as well as other branches of knowledge, may adopt greater informality and may cease to idealise rigorous argument.2. From parents to premissesI will start by examining how and why rigorous, formal argument became an ideal in the first place. This is a long story, going back to the origins of Western literature; so I am forced to be brief.1 I will start with the matter of how argument became an ideal. The first thing we should recognise is that even in the West's earliest literary works—the Iliad and the Odyssey—there are plenty of rudimentary arguments, particularly in the speeches put into the mouths of the major characters. Nevertheless, for sustained or rigorous argument, we must look a little harder. Havelock has put forward the following passage as an example of unusual rigour in early literature (Havelock 1966b, 209). The passage is taken from the start of Hesiod's poem, Works and Days, a piece of wisdom literature almost as old as... (shrink)
