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.

Does perception provide us with direct and unmediated access to the world around us? The so-called 'argument from illusion ' has traditionally been supposed to show otherwise: from the subject's point of view, perceptual illusions are often indistinguishable from veridical perceptions; hence, perceptual experience, as such, cannot provide us with knowledge of the world, but only with knowledge of how things appear to us. Disjunctive accounts of perceptual experience, first proposed by John McDowell and Paul Snowdon in the early 1980s and at the centre of current debates in the philosophy of perception, have been proposed to block this argument. According to the traditional view, a case of perception and a subjectively indistinguishable illusion or hallucination can exemplify what is fundamentally the same kind of mental state even though they differ in how they relate to the non-mental environment. In contrast, according to the disjunctive account, the concept of perceptual experience should be seen as essentially disjunctive, encompassing (at least) two distinct kinds of mental states, namely genuinely world-involving perceptions and mere appearances. This book presents seven recent essays on disjunctivism first published in two special issues of Philosophical Explorations: An International Journal for the Philosophy of Mind and Action.

Classic texts that define the disjunctivist theory of perception.

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.

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.

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.

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.

This book provides a comprehensive account of the intentionality of perceptual experience. With special emphasis on vision Searle explains how the raw phenomenology of perception sets the content and the conditions of satisfaction of experience. The central question concerns the relation between the subjective conscious perceptual field and the objective perceptual field. Everything in the objective field is either perceived or can be perceived. Nothing in the subjective field is perceived nor can be perceived precisely because the events in the subjective field consist of the perceivings, whether veridical or not, of the events in the objective field. Searle begins by criticizing the classical theories of perception and identifies a single fallacy, what he calls the Bad Argument, as the source of nearly all of the confusions in the history of the philosophy of perception. He next justifies the claim that perceptual experiences have presentational intentionality and shows how this justifies the direct realism of his account. In the central theoretical chapters, he shows how it is possible that the raw phenomenology must necessarily determine certain form of intentionality. Searle introduces, in detail, the distinction between different levels of perception from the basic level to the higher levels and shows the internal relation between the features of the experience and the states of affairs presented by the experience. The account applies not just to language possessing human beings but to infants and conscious animals. He also discusses how the account relates to certain traditional puzzles about spectrum inversion, color and size constancy and the brain-in-the-vat thought experiments. In the final chapters he explains and refutes Disjunctivist theories of perception, explains the role of unconscious perception, and concludes by discussing traditional problems of perception such as skepticism.

As a Festschrift, this book celebrates and honours the scholarly achievements of Professor Jaysankar Lal Shaw, one of the most eminent and internationally acclaimed comparative philosophers of our times. Original works by leading international philosophers and logicians are presented here, exploring themes such as: meaning, negation, perception and Indian and Buddhist systems of philosophy, especially Nyaya perspectives. Professor Shaw’s untiring effort to solve some of the problems of contemporary philosophy of language, logic, epistemology, metaphysics and morals from the perspectives of classical Indian philosophers or systems of philosophy is deserving of a tribute. Chapters in this volume reflect the diverse aspects of Shaw’s contribution to comparative philosophy and are organised into four sections: Language, Epistemology, Mathematics and Logic, Ethics and Politics. These chapters would appeal to anyone interested in philosophy or East-West thinking, including students and professionals. Graduates and researchers with interests in epistemology, metaphysics, political philosophy, logic and non-western philosophy will find this work highly relevant.
