Is Bayesian decision theory a panacea for many of the problems in epistemology and the philosophy of science, or is it philosophical snake-oil? For years a debate had been waged amongst specialists regarding the import and legitimacy of this body of theory. Mark Kaplan had written the first accessible and non-technical book to address this controversy. Introducing a new variant on Bayesian decision theory the author offers a compelling case that, while no panacea, decision theory does in fact have the (...) most profound consequences for the way in which philosophers think about inquiry, criticism and rational belief. The new variant on Bayesian theory is presented in such a way that a non-specialist will be able to understand it. The book also offers new solutions to some classic paradoxes. It focuses on the intuitive motivations of the Bayesian approach to epistemology and addresses the philosophical worries to which it has given rise. (shrink)

"[This book] proposes new foundations for the Bayesian principle of rational action, and goes on to develop a new logic of desirability and probabtility."—Frederic Schick, _Journal of Philosophy_.

Scepticism is a subject which has preoccupied philosophers for two thousand years. This book presents an historical perspective on scepticism by considering contrasting views, such as those of Sextus Empiricus, Descartes and Hume, on why scepticism is important. With its historical perspective and analysis of contemporary discussions, _Scepticism_ provides a broad focus on the subject, differing from other discussions of the topic in the importance it attaches to scepticism both in Greek thought and in pre-twentieth century views generally.

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. (shrink)

We call beliefs reasonable or unreasonable, justified or unjustified. What does this imply about belief? Does this imply that we are responsible for our beliefs and that we should be blamed for our unreasonable convictions? Or does it imply that we are in control of our beliefs and that what we believe is up to us? Reason Without Freedom argues that the major problems of epistemology have their roots in concerns about our control over and responsibility for belief. David Owens (...) focuses on the arguments of Descartes, Locke and Hume - the founders of epistemology - and presents a critical discussion of the current trends in contemporary epistemology. He proposes that the problems we confront today - scepticism, the analysis of knowlege, and debates on epistemic justification - can be tackled only once we have understood the moral psychology of belief. This can be resolved when we realise that our responsibility for beliefs is profoundly different from our rationality and agency, and that memory and testimony can preserve justified belief without preserving the evidence which might be used to justify it. Reason Without Freedom should be of value to those interested in contemporary epistemology, philosophy of mind and action, ethics, and the history of 17th and 18th century. (shrink)

The question of the relationship of the making of value judgments in a typically ethical sense to the methods and procedures of science has been discussed in the literature at least to that point which e. e. cummings somewhere refers to as “The Mystical Moment of Dullness.” Nevertheless, albeit with some trepidation, I feel that something more may fruitfully be said on the subject.

Descartes, and many of the other great epistemologists of the modern period, looked to epistemology to put science and intellectual inquiry generally on a secure foundation. Epistemology’s role was to provide assurances of the reliability of properly conducted inquiry. Indeed, its role was nothing less than to be czar of the sciences and of intellectual inquiry in general. This conception of epistemology is now almost universally regarded as overly grandiose. Nonetheless, Descartes and the other great epistemologists of the modern era (...) were not completely mistaken. Epistemology does have a foundational role to play, but not that of a guarantor of knowledge. Its role, rather, is the less flamboyant but nonetheless theoretically crucial one of providing a philosophically respectable foundation for a general theory of rationality. (shrink)

Repeatedly and successfully, the celebrated Harvard philosopher Robert Nozick has reached out to a broad audience beyond the confines of his discipline, addressing ethical and social problems that matter to every thoughtful person. Here Nozick continues his search for the connections between philosophy and "ordinary" experience. In the lively and accessible style that his readers have come to expect, he offers a bold theory of rationality, the one characteristic deemed to fix humanity's "specialness." What are principles for? asks Nozick. We (...) could act simply on whim, or maximize our self-interest and recommend that others do the same. As Nozick explores rationality of decision and rationality of belief, he shows how principles actually function in our day-to-day thinking and in our efforts to live peacefully and productively with each other. Throughout, the book combines daring speculations with detailed investigations to portray the nature and status of rationality and the essential role that imagination plays in this singular human aptitude.
