Discovering someone disagrees with you is a common occurrence. The question of epistemic significance of disagreement concerns how discovering that another disagrees with you affects the rationality of your beliefs on that topic. This book examines the answers that have been proposed to this question, and presents and defends its own answer.

This monograph offers a fresh perspective on the applicability of mathematics in science. It explores what mathematics must be so that its applications to the empirical world do not constitute a mystery. In the process, readers are presented with a new version of mathematical structuralism. The author details a philosophy of mathematics in which the problem of its applicability, particularly in physics, in all its forms can be explained and justified. Chapters cover: mathematics as a formal science, mathematical ontology: what does it mean to exist, mathematical structures: what are they and how do we know them, how different layers of mathematical structuring relate to each other and to perceptual structures, and how to use mathematics to find out how the world is. The book simultaneously develops along two lines, both inspired and enlightened by Edmund Husserl's phenomenological philosophy. One line leads to the establishment of a particular version of mathematical structuralism, free of "naturalist" and empiricist bias. The other leads to a logical-epistemological explanation and justification of the applicability of mathematics carried out within a unique structuralist perspective. This second line points to the "unreasonable" effectiveness of mathematics in physics as a means of representation, a tool, and a source of not always logically justified but useful and effective heuristic strategies.

Extended Rationality provides a novel account of the structure of epistemic justification. Its central claim builds upon Wittgenstein's idea that epistemic justifications hinge on some basic assumptions and that epistemic rationality extends to these very hinges. It exploits these ideas to address problems such as scepticism and relativism.

This monograph on indirect reports offers insights on the semantics/pragmatics interface and a refinement of the notion of explicature. The volume is written in an engaging style and guides the reader through the theoretical problems and their ramifications. The thorniest problem in the study of indirect reports is their polyphonic nature, and how the listener distinguishes between the reporter's voice and the original speaker's voice, either by contextual clues or, in the absence of such clues, by resorting to pragmatic principles. The introductory chapter discusses the main issues that will be addressed in the volume. The next chapters focus on the various aspects of indirect reports, covering both theory and practical applications.

This is an important collection of new essays on various topics relating to realism and its rivals in metaphysics, logic, metaethics, and epistemology. The contributors include some of the leading authors in these fields and in several cases their essays constitute definitive statements of their views. Although not primarily historical this volume includes discussion of philosophers from the Middle Ages to the present day, from Aquinas to Wittgenstein. No one seriously interested in questions about realism can afford to be without this collection.

"The World Unclaimed" argues that Heidegger's critique of modern epistemology in "Being and Time" is seriously flawed. Heidegger believes he has done away with epistemological problems concerning the external world by showing that the world is an existential structure of Dasein. However, the author argues that Heidegger fails to make good his claim that he has "rescued" the phenomenon of the world, which he believes the tradition of philosophy has bypassed. Heidegger fails not only to reclaim the world but also to acknowledge its loss. Alweiss thus calls into question Heidegger's claim that ontology is more fundamental than epistemology.
"The World Unclaimed" develops its powerful critique of Being and Time by arguing for a return to Husserl. It draws on Husserl's insight that it is the moving and sensing body that discloses how we are already familiar with the world. Kinaesthesia provides a key for understanding our relation to the world. The author thus suggests that thinkers in the vein of Husserl and Kant -who, for Heidegger, epitomize the tradition of modern philosophy by returning to a "worldless subject"- may provide us with the resources to reclaim the phenomenon of the world that "Being and Time" sets out to salvage.
Alweiss's fresh and innovative study demonstrates that it is possible to overcome epistemological skepticism without ever losing sight of the phenomenon of the world. Moreover, Alweiss challenges us to reconsider the relation between Husserl and Heidegger by providing a forceful defense of Husserl's critique of cognition.

Few concepts have been considered as essential to the theory of knowledge and rational belief as that of evidence. The simplest theory which accounts for this is evidentialism, the view that epistemic justification for belief--the kind of justification typically taken to be required for knowledge--is determined solely by considerations pertaining to one's evidence. In this ground-breaking book, leading epistemologists from across the spectrum challenge and refine evidentialism, sometimes suggesting that it needs to be expanded in quite surprising directions. Following this, the twin pillars of contemporary evidentialism--Earl Conee and Richard Feldman--respond to each essay. This engaging debate covers a vast number of issues, and will illuminate and inform.

The Evident Connexion presents a new reading of Hume's 'bundle theory' of the self or mind, and his later rejection of it. Galen Strawson argues that the bundle theory does not claim that there are no subjects of experience, as many have supposed, or that the mind is just a series of experiences. Hume holds only that the 'essence of the mind is] unknown'. His claim is simply that we have no empirically respectable reason to believe in the existence of a persisting subject, or a mind that is more than a series of experiences (each with its own subject).
Why does Hume later reject the bundle theory? Many think he became dissatisfied with his account of how we come to believe in a persisting self, but Strawson suggests that the problem is more serious. The keystone of Hume's philosophy is that our experiences are governed by a 'uniting principle' or 'bond of union'. But a philosophy that takes a bundle of ontologically distinct experiences to be the only legitimate conception of the mind cannot make explanatory use of those notions in the way Hume does. As Hume says in the Appendix to the Treatise of Human Nature having 'loosen'd all our particular perceptions' in the bundle theory, he is unable to 'explain the principle of connexion, which binds them together'. This lucid book is the first to be wholly dedicated to Hume's theory of personal identity, and presents a bold new interpretation which bears directly on current debates among scholars of Hume's philosophy.

Lloyd Gerson offers an original new study of Plato's account of persons, a topic of continuing interest to philosophers. His book locates Plato's psychology within his two-world metaphysics, showing that embodied persons are images of a disembodied ideal, and that they reflect many of the conflicting states of the sensible world. For Plato, Gerson argues, philosophy is the means to recognizing one's true identity.

This volume collects the best and most influential essays on knowledge, rationality and morality that Stephen Stich has published in the last 40 years. All of the essays are concerned, in one way or another, with the ways in which findings and theories in the cognitive sciences can contribute to, and sometimes reshape traditional philosophical conversations and debates. A central theme in the essays on epistemology and rationality is the philosophical significance of empirical work on human reasoning done by researchers in the "heuristics and biases" tradition, and by their critics in evolutionary psychology. In the essays on morality, a wide range of empirical work is explored, including studies of the psychological foundations of norms, work on the moral / conventional distinction, and empirical attempts to determine whether humans ever act on altruistic motives. Stich was one of the pioneers in the experimental philosophy movement, and work in experimental philosophy plays a prominent role in many of these essays. The volume includes a new introductory essay that offers an overview of the papers and traces the history of how they emerged.

Ludwig Wittgenstein's Tractatus Logico-Philosophicus (1922) remains one of the most enigmatic works of twentieth century thought. In this bold and original new study, Ben Ware argues that Wittgenstein's early masterpiece is neither an analytic treatise on language and logic, nor a quasi-mystical work seeking to communicate 'ineffable' truths. Instead, we come to understand the Tractatus by grasping it in a twofold sense: first, as a dialectical work which invites the reader to overcome certain 'illusions of thought'; and second as a modernist work whose anti-philosophical ambition is intimately tied to its radical aesthetic character. By placing the Tractatus in the force field of modernism, Dialectic of the Ladder clears the ground for a new and challenging exploration of the work's ethical dimension. It also casts new light upon the cultural, aesthetic and political significances of Wittgenstein's writing, revealing hitherto unacknowledged affinities with a host of philosophical and literary authors, including Hegel, Kierkegaard, Marx, Nietzsche, Adorno, Benjamin, and Kafka.

This is the first volume dedicated to a direct exploration of Wittgenstein and Plato. It is a compilation of essays by thirteen authors of diverse geographical provenance, orientation and philosophical interest.
The volume offers the most complete and detailed view to date on Wittgenstein and Plato, without being tied to any unilateral guidelines from either a critical or philosophical perspective. The authors are scholars of Wittgenstein, but also of Plato and Greek philosophy. The book is a sort of game of mirrors: Plato in the mirror of Wittgenstein, and Wittgenstein in the mirror of Plato. All essays always seek to combine philosophical interest and philological attention, although, in some essays one interest prevails over the other.
Despite the preponderance of scholars of Wittgenstein, the volume seeks to be not only a book on Wittgenstein and Plato, but also, simultaneously, on Plato and Wittgenstein.

Markus Seidel provides a detailed critique of epistemic relativism in the sociology of scientific knowledge. In addition to scrutinising the main arguments for epistemic relativism he provides an absolutist account that nevertheless aims at integrating the relativist's intuition.

This book investigates the impact of misinformation and the role of truth in political struggle. It develops a theory of objective truth for political controversy over topics such as racism and gender, based on the insights of intersectionality, the Black feminist theory of interlocking systems of oppression. Truth is defined using the tools of model theory and formal semantics, but the theory also captures how social power dynamics strongly influence the operation of the concept of truth within the social fabric. Systemic ignorance, propagated through false speech and misinformation, sustains oppressive power structures and perpetuates systemic inequity. Truth tends to empower marginalized groups precisely because oppressive systems are maintained through systemic ignorance. If the truth sets people free, then power will work to obscure it. Hence, the rise of misinformation as a political weapon is a strategy of dominant power to undermine the political advancement of marginalized groups.

In this book the main trends, concepts and directions in cartography and mapping in modernism and post-modernism are reviewed. Philosophical and epistemological issues are analysed in cartography from positivist-empiricist, neo-positivist and post-structuralist stances. In general, in cartography technological aspects have been considered as well as theoretical issues. The aim is to highlight the epistemological and philosophical viewpoint during the development of the discipline. Some main philosophers who have been influential for contemporary thinking such as Immanuel Kant, Ludwig Wittgenstein, Karl Popper and Bertrand Russell, are considered. None of these philosophers wrote about cartography directly (excepting Kant), but their philosophies are related to cartography and mapping issues. The book also analyses the concept of paradigm or paradigm shift coined by Thomas Kuhn, who applied it to the history of science. Different cartographic trends that have arisen since the second half of the twentieth century are analysed according to this important concept which is implicit inside the scientific or disciplinary communities. Further, the authors analyse the position of cartography in the context of the sciences and other disciplines, adopting a positivistic point of view. Additionally, they review current trends in cartography and mapping in the context of information and communication technologies in a post-modernistic or post-structuralistic framework. Thus, since the 1980s and 1990s, new mapping concepts have arisen which challenge the discipline's traditional map conceptions.

Is critical argumentation an effective way to overcome disagreement? And does the exchange of arguments bring opponents in a controversy closer to the truth? This study provides a new perspective on these pivotal questions. By means of multi-agent simulations, it investigates the truth and consensus-conduciveness of controversial debates. The book brings together research in formal epistemology and argumentation theory. Aside from its consequences for discursive practice, the work may have important implications for philosophy of science and the way we construe scientific rationality as well.

Using the example of prehistoric paintings discovered in the late 19th century in Spain and France 'Cave Art, Perception and Knowledge' inquires into epistemic questions related to images, depicting and perception to which this rich material has given rise. The book traces the outline of the doxa of cave art studies.

"The Crisis of Causality" deals with the reaction of the Dutch Calvinist theologian Gisbertus Voetius (1589-1676) to the "New Philosophy" of Rene Descartes (1596-1650). Voetius not only criticised the Cartesian idea of a mechanical Universe; he also foresaw that shifting conceptions of natural causality would make it impossible for theologians to explain the relationship between God and Creation in philosophical terms. This threatened the status of theology as a scientific discipline. Apart from a detailed analysis of the Scholastic and Cartesian notions of causality, the book offers new perspectives on related subjects, such as seventeenth-century university training and the Cartesian method of science. It will be of great importance to any student of seventeenth-century intellectual history, philosophy, theology and history of science.

Truth Through Proof defends an anti-platonist philosophy of mathematics derived from game formalism. Classic formalists claimed implausibly that mathematical utterances are truth-valueless moves in a game. Alan Weir aims to develop a more satisfactory successor to game formalism utilising a widely accepted, broadly neo-Fregean framework, in which the proposition expressed by an utterance is a function of both sense and background circumstance. This framework allows for sentences whose truth-conditions are not representational, which are made true or false by conditions residing in the circumstances of utterances but not transparently in the sense.
Applications to projectivism and fiction pave the way for the claim that mathematical utterances are made true or false by the existence of concrete proofs or refutations, though these truth-making conditions form no part of their sense or informational content.
The position is compared with rivals, an account of the applicability of mathematics developed, and a new account of the nature of idealisation proffered in which it is argued that the finitistic limitations Godel placed on proofs are without rational justification. Finally a non-classical logical system is provided in which excluded middle fails, yet enough logical power remains to recapture the results of standard mathematics.

This book presents an in-depth perspective of knowledge as a fundamental process of any organization rather than just another resource to be managed. The author presents a process-oriented theory of creating and applying knowledge directed towards bothresearchers and practitioners. In this book the author develops normative knowledge management guidelines which draw from a unique view on knowledge, discussed in the field of philosophy since Plato but neglected by most knowledgemanagement authors - by applying a philosophically grounded 'social epistemology' to organizations. The guidelines in this book call for an open and reflective space of knowledge creation, aligned with goals and structures of the organization. Numerous examples, field studies, and an application to the main case study on Seven-Eleven Japan complement both the descriptive view on knowledge as well as the normative guidelines presented in this book.

For the first time Truth: A Contemporary Reader brings together essays that have shaped two aspects of a fundamental philosophical topic: the nature of truth and the value of truth. Featuring 22 essays, this up-to-date reader includes seminal work by leading figures in contemporary analytic philosophy. It charts the development of the central 'grand proposals' about the nature of truth, and subsequently how their influence gradually diminished in face of new theories developed in the 20th and 21st-centuries. The reader also demonstrates how truth is often taken to be valuable in various ways, in particular as the norm of correctness for belief and assertion, and the relationship between truth and other epistemic values. With introductory overviews to each group of related papers complemented by guides to further reading, this reader introduces the central debates, familiarizes students with the most important work in the field and covers pivotal theories of truth including: - correspondence theories - coherentism, pragmatism, verificationism - deflationary, primitivist, and pluralist theories Moreover, by showing how thoughts about truth and value bear heavily on one another, Truth: A Contemporary Reader provides new opportunities for understanding and advancing the link between these central topics. This is an essential collection for anyone studying or working in metaphysics, epistemology, and the philosophy of language today.

John Foster presents a clear and powerful discussion of a range of topics relating to our understanding of the universe: induction, laws of nature, and the existence of God. He begins by developing a solution to the problem of induction - a solution whose key idea is that the regularities in the workings of nature that have held in our experience hitherto are to be explained by appeal to the controlling influence of laws, as forms of natural necessity. His second line of argument focuses on the issue of what we should take such necessitational laws to be, and whether we can even make sense of them at all. Having considered and rejected various alternatives, Foster puts forward his own proposal: the obtaining of a law consists in the causal imposing of a regularity on the universe as a regularity. With this causal account of laws in place, he is now equipped to offer an argument for theism. His claim is that natural regularities call for explanation, and that, whatever explanatory role we may initially assign to laws, the only plausible ultimate explanation is in terms of the agency of God. Finally, he argues that, once we accept the existence of God, we need to think of him as creating the universe by a method which imposes regularities on it in the relevant law-yielding way. In this new perspective, the original nomological-explanatory solution to the problem of induction becomes a theological-explanatory solution. The Divine Lawmaker is bold and original in its approach, and rich in argument. The issues on which it focuses are among the most important in the whole epistemological and metaphysical spectrum.

Quid est secretum? Visual Representation of Secrets in Early Modern Europe, 1500-1700 is the companion volume to Intersections 65.1, Quid est sacramentum? Visual Representation of Sacred Mysteries in Early Modern Europe, 1400-1700. Whereas the latter volume focused on sacramental mysteries, the current one examines a wider range of secret subjects. The book examines how secret knowledge was represented visually in ways that both revealed and concealed the true nature of that knowledge, giving and yet impeding access to it. In the early modern period, the discursive and symbolical sites for the representation of secrets were closely related to epistemic changes that transformed conceptions of the transmissibility of knowledge.
