Rational Belief

Rational Belief provides conceptions of belief and knowledge, offers a theory of how they are grounded, and connects them with the will and thereby with action, moral responsibility, and intellectual virtue. A unifying element is a commitment to representing epistemology-which is centrally concerned with belief-as integrated with a plausible philosophy of mind that does justice both to the nature of belief and to the conditions for its formation and regulation. Part One centers on belief and its relation to the will. It explores our control of our beliefs, and it describes several forms belief may take and shows how beliefs are connected with the world outside the mind. Part Two concerns normative aspects of epistemology, explores the nature of intellectual virtue, and presents a theory of moral perception. The book also offers a theory of the grounds of both justification and knowledge and shows how these grounds bear on the self-evident. Rationality is distinguished from justification; each clarified in relation to the other; and the epistemological importance of the phenomenal-for instance, of intuitional experience and other "private" aspects of mental life-is explored. The final section addresses social epistemology. It offers a theory of testimony as essential in human knowledge and a related account of the rational resolution of disagreements.

The papers collected in this volume were originally presented at a sym posium held at the University of Pennsylvania in December of 1968. Each of the papers has been revised in light of the discussions that took place during this symposium. None of the papers has appeared in print previously. The extensive bibliography that appears at the end of the volume was originally distributed during the symposium and was revised on the basis of many helpful suggestions made by those who participated. The symposium was made possible by a grant from The National Science Foundation and funds contributed by the Philosophy Depart ment of the University of Pennsylvania. On behalf of the contributors to this volume, I would like to express my thanks to these organizations for their generous support. In addition, I would like to express my gratitude to the members of the Graduate Philosophy Students Organization at the University of Penn sylvania for the considerable assistance they gave me during the sym posium. My thanks, also, to Judith Sofranko and Lynn Luckett for their very responsible efforts in the preparation of the manuscript. Finally, I would like to thank Professor James Cornman for his invaluable advice and encouragement.

The book offers new insights into the lottery paradox, and thereby into how categorical and graded beliefs are formally connected.

In Rational and Irrational Beliefs: Research, Theory, and Clinical Practice, leading scholars, researchers, and practitioners of rational emotive behavior therapy (REBT) and other cognitive-behavioral therapies (CBTs) share their perspectives and empirical findings on the nature of rational and irrational beliefs, the role of beliefs as mediators of functional and dysfunctional emotions and behaviors, and clinical approaches to modifying irrational beliefs, enhancing rational beliefs, and adaptive coping in the face of stressful life events. Offering a comprehensive and cohesive approach to understanding REBT/CBT and its central constructs of rational and irrational beliefs, contributors review a steadily accumulating empirical literature indicating that irrational beliefs are associated with a wide range of problems in living and that exposure to rational self-statements can decrease anxiety and other psychological symptoms, and play a valuable role in health promotion and disease prevention. Contributors also identify new frontiers of research and theory, including the link between irrational beliefs and other cognitive processes such as memory, psychophysiological responses, and evolutionary and cultural determinants of rational and irrational beliefs. A truly accessible, state-of-the-science summary of REBT/CBT research and clinical applications, Rational and Irrational Beliefs is an invaluable resource for psychotherapy practitioners of all theoretical orientations, as well as instructors, students, and academic psychologists.

Does logic help determine whether beliefs are rational? The author argues that it does - but only once we understand beliefs as coming in degrees. He explains the degree-of-belief approach offers the key to understanding how logical arguments work.

In everyday life we normally express our beliefs in all-or-nothing terms: I believe it is going to rain; I don't believe that my lottery ticket will win. In other cases, if possible, we resort to numerical probabilities: my degree of belief that it is going to rain is 80%; the probability that I assign to my ticket winning is one in a million. It is an open philosophical question how all-or-nothing belief and numerical belief relate to each other, and how we ought to reason with them simultaneously. The Stability of Belief develops a theory of rational belief that aims to answer this question. Hannes Leitgeb develops a joint normative theory of all-or-nothing belief and numerical degrees of belief. While rational all-or-nothing belief is studied in traditional epistemology and is usually assumed to obey logical norms, rational degrees of belief constitute the subject matter of Bayesian epistemology and are normally taken to conform to probabilistic norms. One of the central open questions in formal epistemology is what beliefs and degrees of belief have to be like in order for them to cohere with each other. The answer defended in this book is a stability account of belief: a rational agent believes a proposition just in case the agent assigns a stably high degree of belief to it. Leitgeb determines this theory's consequences for, and applications to, learning, suppositional reasoning, decision-making, assertion, acceptance, conditionals, and chance. The volume builds new bridges between logic and probability theory, traditional and formal epistemology, theoretical and practical rationality, and synchronic and diachronic norms for reasoning.

If God exists, why doesn't he eliminate suffering and evil? Does evolution disprove Christianity? Can religion be explained by cognitive science? People have grappled for ages with these kinds of questions. And many in today's academic world find Christian belief untenable. But renowned philosopher Stephen Davis argues that belief in God is indeed a rational and intellectually sound endeavor. Drawing on a lifetime of rigorous reflection and critical thinking, he explores perennial and contemporary challenges to Christian faith. Davis appraises objections fairly and openly, offering thoughtful approaches to common intellectual problems. Real questions warrant reasonable responses. Examine for yourself the rationality of the Christian faith.

Extensively updated to include clinical findings over the last two decades, this third edition of A Practitioner's Guide to Rational-Emotive Behavior Therapy reviews the philosophy, theory, and clinical practice of Rational Emotive Behavior Therapy (REBT). This model is based on the work of Albert Ellis, who had an enormous influence on the field of psychotherapy over his 50 years of practice and scholarly writing. Designed for both therapists-in-training and seasoned professionals, this practical treatment manual and guide introduces the basic principles of rational-emotive behavior therapy, explains general therapeutic strategies, and offers many illustrative dialogues between therapist and patient. The volume breaks down each stage of therapy to present the exact procedures and skills therapists need, and numerous case studies illustrate how to use these skills. The authors describe both technical and specific strategic interventions, and they stress taking an integrative approach. The importance of building a therapeutic alliance and the use of cognitive, emotive, evocative, imaginal, and behavioral interventions serves as the unifying theme of the approach. Intervention models are presented for the treatment of anxiety, depression, trauma, anger, personality disorders, and addictions. Psychologists, clinical social workers, mental health counselors, psychotherapists, and students and trainees in these areas will find this book useful in learning to apply rational-emotive behavior therapy in practice.
