David Hume launched a historic revolution in epistemology when he showed that our theories about the world have no probability relative to what we think of as our evidence for them, hence that the distinction between justified and unjustified theories does not lie in their different probabilities relative to that evidence. However, allies in his revolution appeared only in the 20th century, in the persons of Sir Karl Popper, Nelson Goodman and W. V. Quine. Hume's second great contribution to the field, which remains unrecognized to this day, was to propose what is now known as reflective equilibrium theory as the framework within which justified and unjustified theories are rightly distinguished. The core of this book comprises an account of these developments from Hume to Quine, an extension of reflective equilibrium theory that renders it a general theory of epistemic justification concerning our beliefs about the world, and an argument that all four of these thinkers would have endorsed that extension. In chapters on Sextus, Descartes, Wittgenstein's On Certainty, and other aspects of Hume's epistemology I defend new readings of those philosophers' writings on skepticism and note significant relationships among their views on matters bearing on the Humean revolution. Finally, in chapters on Hilary Putnam's "Brains in a Vat" and Fred Dretske's contextualism - the only promising version of that view - I show that both fail to rule out the possible truth of radical skeptical hypotheses. This is not surprising, since those hypotheses are in fact possible. They are not, however, of any epistemological significance, since the justification of our beliefs about the world is a function of the extent to which bodies of beliefs to which they belong are in reflective equilibrium, and no extant conception of knowledge is of any epistemological interest.

Righting Epistemology defends an unrecognized Humean conception of epistemic justification, showing that he is no skeptic, and an argument of his that refutes all extant alternative conceptions. It goes on to trace the development of his thought in Sir Karl Popper, Nelson Goodman, W. V. Quine and Ludwig Wittgenstein.

Philosophy has long embraced epistemology as one of its central elements. What is knowledge? How do we gain it? Can we gain it? Or do we always deceive ourselves when thinking that we have knowledge? Are we too deeply fallible ever to know something? For centuries, these questions have helped to define and motivate epistemological research. This volume engages strikingly with them, offering some unusual answers. Stephen Hetherington's prominent career within epistemology has been a series of bold, varied and provocative arguments and ideas. Bringing together some elements of his unique body of writing for the first time, this collection features previously published as well as new material displaying and extending some of his highly original approaches to key issues including knowledge, justification, fallibility, scepticism and the Gettier Problem. Advancing our understanding of the systemic nature of Hetherington's thinking, Stephen Hetherington on Epistemology presents his distinctive perspective on some of philosophy's central questions about knowledge – an inviting blend of forensic detail and 'big picture' proposals.

In this book, W. V. Quine’s Immanuel Kant Lectures entitled Science and Sensibilia are published for the first time in English. These lectures represent an important stage in the development of Quine’s later thought, where he is more explicit about the importance of physicalist constraints in his account of the steps from sensory stimulation to scientific theory, and in further using them to assess the extent to which mental vocabulary is defensible. Taken as a unit, these lectures fill an important gap in our understanding of his philosophical development from his 1973 work The Roots of Reference to his later work. The volume further contains an introduction that outlines the content and philosophical significance of the lectures. In addition, several essays written by leading scholars of Quine’s philosophy provide further insight into the important issues raised in the lectures.

This volume collects the most influential essays of philosopher Linda Trinkaus Zagzebski, one of the most distinguished thinkers working in epistemology today, particularly where the theory of knowledge meets ethics and the philosophy of religion. The volume is organized into six key topics in epistemology: knowledge and understanding, intellectual virtue, epistemic value, virtue in religious epistemology, intellectual autonomy and authority, and skepticism and the Gettier problem.

Plato's Epistemology presents an original interpretation of one of the central topics in Plato's work: epistemology. Moss argues, against the grain of much modern scholarship, that Plato's epistemology is radically different from our own.

This book is about normativity and reasons. But by the end the subject becomes the relation between self, thought and world. Skorupski argues that the key concepts of epistemology and moral theory are normative concepts, and that what makes them normative is that they depend on reasons. The concept of a reason is fundamental to all thought.

Can we have objective knowledge of right and wrong, of how we should live and what there is reason to do? Can it be anything but luck when our beliefs are true? Kieran Setiya confronts these questions in their most compelling and articulate forms, and argues that if there is objective ethical knowledge, human nature is its source.
