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.

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 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.

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.

Epistemic Angst offers a completely new solution to the ancient philosophical problem of radical skepticism—the challenge of explaining how it is possible to have knowledge of a world external to us. Duncan Pritchard argues that the key to resolving this puzzle is to realize that it is composed of two logically distinct problems, each requiring its own solution. He then puts forward solutions to both problems. To that end, he offers a new reading of Wittgenstein's account of the structure of rational evaluation and demonstrates how this provides an elegant solution to one aspect of the skeptical problem. Pritchard also revisits the epistemological disjunctivist proposal that he developed in previous work and shows how it can effectively handle the other aspect of the problem. Finally, he argues that these two antiskeptical positions, while superficially in tension with each other, are not only compatible but also mutually supporting. The result is a comprehensive and distinctive resolution to the problem of radical skepticism, one that challenges many assumptions in contemporary epistemology.

Disjunctivism is the focus of a lively debate spanning the philosophy of perception, epistemology, and the philosophy of action. Adrian Haddock and Fiona Macpherson present 17 specially written essays, which examine the different forms of disjunctivism and explore the connections between them.
