This is the first volume dedicated solely to the topic of epistemological disjunctivism. The original essays in this volume, written by leading and up-and-coming scholars on the topic, are divided into three thematic sections. The first set of chapters addresses the historical background of epistemological disjunctivism. It features essays on ancient epistemology, Immanuel Kant, J.L. Austin, Edmund Husserl, and Ludwig Wittgenstein. The second section tackles a number contemporary issues related to epistemological disjunctivism, including its relationship with perceptual disjunctivism, radical skepticism, and reasons for belief. Finally, the third group of essays extends the framework of epistemological disjunctivism to other forms of knowledge, such as testimonial knowledge, knowledge of other minds, and self-knowledge. Epistemological Disjunctivism is a timely collection that engages with an increasingly important topic in philosophy. It will appeal to researches and graduate students working in epistemology, philosophy of mind, and philosophy of perception.

Duncan Pritchard offers an account of perceptual knowledge, arguing that it is paradigmatically constituted by true belief that enjoys rational support which is reflectively accessible to the agent. This resolves the issue between intermalism and externalism, and poses a radical challenge to contemporary epistemology.

Offering a philosophical examination of the concept of luck and its relationship to knowledge, this text demonstrates how a more nuanced understanding of the relationship between knowledge and luck can enable us to see past some of the most intractable disputes in the contemporary theory of knowledge.

Duncan Pritchard offers an original defence of epistemological disjunctivism. This is an account of perceptual knowledge which contends that such knowledge is paradigmatically constituted by a true belief that enjoys rational support which is both factive and reflectively accessible to the agent. In particular, in a case of paradigmatic perceptual knowledge that p, the subject's rational support for believing that p is that she sees that p, where this rational support is both reflectively accessible and factive (i.e., it entails p). Such an account of perceptual knowledge poses a radical challenge to contemporary epistemology, since by the lights of standard views in epistemology this proposal is simply incoherent. Pritchard's aim in Epistemological Disjunctivism is to show that this proposal is theoretically viable (i.e., that it does not succumb to the problems that it appears to face), and also to demonstrate that this is an account of perceptual knowledge which we would want to endorse if it were available on account of its tremendous theoretical potential. In particular, he argues that epistemological disjunctivism offers a way through the impasse between epistemic externalism and internalism, and also provides the foundation for a distinctive response to the problem of radical scepticism.

It is commonly held that the experiences involved in cases of perception, illusion and hallucination all have the same nature. Disjunctivists deny this. They maintain that the kind of experience you have when you perceive the world isn’t one you could be having if you were hallucinating. A number of important debates in the philosophy of mind and epistemology turn on the question of whether this disjunctivist view is tenable. This is the first book-length introduction to this contested issue. Matthew Soteriou explains the accounts of perception that disjunctivists seek to defend, such as naïve realism, and the accounts to which they are opposed, such as sense-datum theories and representationalist theories. He goes on to introduce and assess key questions that arise in these debates: Is disjunctivism consistent with what has been established by the science of perception? Does introspective reflection support naïve realism? Can disjunctivism be motivated by appeal to the role that perception plays in enabling us to think demonstratively about mind-independent objects and qualities in our environment? Does disjunctivism offer the best account of perceptual knowledge? What can disjunctivists say about the nature of hallucination and illusion? Including chapter summaries, annotated further reading and a glossary, this book is an ideal starting point for anyone studying disjunctivism for the first time, as well as for more advanced students and researchers.

Disjunctivism has attracted considerable philosophical attention in recent years: it has been the source of a lively and extended debate spanning the philosophy of perception, epistemology, and the philosophy of action. Adrian Haddock and Fiona Macpherson present seventeen specially written essays, which examine the different forms of disjunctivism and explore the connections between them. This volume will be an essential resource for anyone working in the central areas of philosophy, and the starting point for future research in this fascinating field.

We ordinarily take it as obvious that we acquire knowledge of our world on the basis of sensory perception, and that such knowledge plays a central cognitive and practical role in our lives. Upon reflection, however, it is far from obvious what perception involves and how exactly it contributes to our knowledge. Indeed, skeptical arguments have led some to question whether we have any knowledge, or even rational or justified belief, regarding the world outside our minds. Investigating the nature and scope of our perceptual knowledge and perceptually justified belief, A Critical Introduction to the Epistemology of Perception provides an accessible and engaging introduction to a flourishing area of philosophy. Before introducing and evaluating the main theories in the epistemology of perception, Ali Hasan sets the stage with a discussion of skepticism, realism, and idealism in early modern philosophy, theories of perceptual experience (sense-datum theory, adverbialism, intentionalism, and metaphysical disjunctivism), and central controversies in general epistemology. Hasan then surveys the main theories in the contemporary debate, including coherentism, abductivism, phenomenal conservatism or dogmatism, reliabilism, and epistemological disjunctivism, presenting the motivations and primary objections to each. Hasan also shows how to avoid confusing metaphysical issues with epistemological ones, and identifies interesting connections between the epistemology and metaphysics of perception. For students in epistemology or the philosophy of perception looking to better understand the central questions, concepts, and debates shaping contemporary epistemology, A Critical Introduction to the Epistemology of Perception is essential reading.
