In his widely influential two-volume work, Warrant: The Current Debate and Warrant and Proper Function, Alvin Plantinga argued that warrant is that which explains the difference between knowledge and true belief. Plantinga not only developed his own account of warrant but also mapped the terrain of epistemology. Motivated by Plantinga's work, fourteen prominent philosophers have written new essays investigating Plantingian warrant and its contribution to contemporary epistemology. The resulting collection, representing a broad array of views, not only gives readers a critical perspective on Plantinga's landmark work, but also provides in one volume a clear statement of the variety of approaches to the nature of warrant within contemporary epistemology, and to the connections between epistemology and metaphysics. Positions covered include internalism and externalism, reliabilism, coherentism and foundationalism, virtue theories, and defensibility theories. Alvin Plantinga responds to the essays in his own contribution.

Riddles of Existence makes metaphysics genuinely accessible, even fun. Its lively, informal style brings the riddles to life and shows how stimulating they can be to think about. No philosophical background is required to enjoy this book. It is ideal for beginning students. Anyone wanting to think about life's most profound questions will find Riddles of Existence provocative and entertaining. This new edition is updated throughout, and features two extra, specially written chapters: one on metaphysical questions to do with morality, and the other on questions about the nature of metaphysics itself.

Evidentialism is a theory of knowledge whose essence is the traditional idea that the justification of factual knowledge is entirely a matter of evidence. Earl Conee and Richard Feldman present the definitive exposition and defence of this much-contested theory. They argue that evidentialism is an asset virtually everywhere in epistemology, from getting started legitimately to refuting skepticism. The volume collects the authors' renowned work on the topic and adds substantial new material, making it the prime resource in evidentialism for all epistemologists.

Evidentialism is a view about the conditions under which a person is epistemically justified in having a particular doxastic attitude toward a proposition. Evidentialism holds that the justified attitudes are determined entirely by the person's evidence. This is the traditional view of justification. It is now widely opposed. The essays included in this volume develop and defend the tradition. Evidentialism has many assets. In addition to providing an intuitively plausible account of epistemic justification, it helps to resolve the problem of the criterion, helps to disentangle epistemic and ethical evaluations, and illuminates the relationship between epistemic evaluations of beliefs and the evaluation of the methods used to form beliefs. These issues are all addressed in the essays presented here. External world skepticism poses the classic problem for an epistemological theory. The final essay in this volume argues that evidentialism is uniquely well qualified to make sense of skepticism and to respond to its challenge. Evidentialism is a version of epistemic internalism. Recent epistemology has included many attacks on internalism and has seen the development of numerous externalist theories. The essays included here respond to those attacks and raise objections to externalist theories, especially the principal rival, reliabilism. Internalism generally has been criticized for having unacceptable deontological implications, for failing to connect epistemic justification to truth, and for failing to provide an adequate account of what makes basic beliefs justified. Each of these charges is answered in these essays. The collection includes two previously unpublished essays and new afterwords to five of the reprinted essays; it will be the definitive resource on evidentialism for all epistemologists.
