Assertion is a fundamental feature of language. This volume will be the place to look for anyone interested in current work on the topic. Philosophers of language and epistemologists join forces to elucidate what kind of speech act assertion is, particularly in light of relativist views of truth, and how assertion is governed by epistemic norms.

What strength of evidence is required for knowledge? Ordinarily, we often claim to know something on the basis of evidence which doesn't guarantee its truth. For instance, one might claim to know that one sees a crow on the basis of visual experience even though having that experience does not guarantee that there is a crow (it might be a rook, or one might be dreaming). As a result, those wanting to avoid philosophical scepticism have standardly embraced "fallibilism": one can know a proposition on the basis of evidence that supports it even if the evidence doesn't guarantee its truth. Despite this, there's been a persistent temptation to endorse "infallibilism", according to which knowledge requires evidence that guarantees truth. For doesn't it sound contradictory to simultaneously claim to know and admit the possibility of error? Infallibilism is undergoing a contemporary renaissance. Furthermore, recent infallibilists make the surprising claim that they can avoid scepticism.Jessica Brown presents a fresh examination of the debate between these two positions. She argues that infallibilists can avoid scepticism only at the cost of problematic commitments concerning evidence and evidential support. Further, she argues that alleged objections to fallibilism are not compelling. She concludes that we should be fallibilists. In doing so, she discusses the nature of evidence, evidential support, justification, blamelessness, closure for knowledge, defeat, epistemic akrasia, practical reasoning, concessive knowledge attributions, and the threshold problem.

Traditionally, the notion of defeat has been central to epistemology, practical reasoning, and ethics. Within epistemology, it is standardly assumed that a subject who knows that p, or justifiably believes that p, can lose this knowledge or justified belief by acquiring a so-called 'defeater', whether that is evidence that not-p, evidence that the process that produced her belief is unreliable, or evidence that she has likely misevaluated her own evidence. Within ethics and practical reasoning, it is widely accepted that a subject may initially have a reason to do something although this reason is later defeated by her acquisition of further information. However, the traditional conception of defeat has recently come under attack. Some have argued that the notion of defeat is problematically motivated; others that defeat is hard to accommodate within externalist or naturalistic accounts of knowledge or justification; and still others that the intuitions that support defeat can be explained in other ways. This volume presents new work re-examining the very notion of defeat, and its place in epistemology and in normativity theory at large.

Organised groups such as governments, corporations, charities and courts are an integral part of our lives. They provide services, sell goods, employ people, raise taxes, wage wars, and issue legal judgements. In our interactions with them, we routinely ascribe them mental states, speaking of what they know, want and intend. And we use these ascriptions in predicting what groups will do and assessing their responsibility for outcomes. For instance, in morally assessing the government's performance in the coronavirus pandemic, we might ask what the government knew about the virus at key decision points. And in attempting to predict Russia's response to the current war in Ukraine, we might ask what Russia believes about the West's resolve to defend Ukraine. This book takes these ordinary ways of thinking and talking seriously, assuming that at least some groups are agents with mental states on which they act. In particular, the book examines groups both as epistemic and moral agents providing non-summative accounts of group evidence, group belief, group justified belief, group knowledge, what it is for a group to act or believe for one reason rather than another, and when a group has an excuse for wrongdoing from blameless ignorance. These phenomena are crucial to the evaluation of the beliefs and actions of groups. Whether a group's belief is justified depends on its evidence and the reason for which it believes; whether it's praiseworthy or blameworthy for its actions depends on the reason for which it acted, as well as whether it is blamelessly ignorant of any wrongdoing. By providing a clearer view of central group phenomena, the book will help us assess the beliefs and actions of the powerful groups at work in our lives, whether governments, corporations, public sector bodies or third sector actors.

Knowledge ascriptions, such as 'Sam knows that Obama is president of the United States', play a central role in our cognitive and social lives. For example, they are closely related to epistemic assessments of action. As a result, knowledge ascriptions are a central topic of research in both philosophy and science. In this collection of new essays on knowledge ascriptions, world class philosophers offer novel approaches to this long standing topic. The contributions exemplify three recent approaches to knowledge ascriptions. First, a linguistic turn according to which linguistic phenomena and theory are an important resource for providing an adequate account of knowledge ascriptions. Second, a cognitive turn according to which empirical theories from, for example, cognitive psychology as well as experimental philosophy should be invoked in theorizing about knowledge ascriptions. Third, a social turn according to which the social functions of knowledge ascriptions to both individuals and groups are central to understanding knowledge ascriptions. In addition, since knowledge ascriptions have figured very prominently in discussions concerning philosophical methodology, many of the contributions address or exemplify various methodological approaches.The editors, Jessica Brown and Mikkel Gerken, provide a substantive introduction that gives an overview of the various approaches to this complex debate, their interconnections, and the wide-ranging methodological issues that they raise.
