5-Volume Set. Nicholas Rescher is University Professor of Philosophy at the University of Pittsburgh where he also served for many years as Director of the Center for Philosophy of Science. He is a former president of the Eastern Division of the American Philosophical Association, and has also served as President of the American Catholic Philosophical Association, the American Metaphysical Society, the American G W Leibniz Society, and the C S Peirce Society. An honorary member of Corpus Christi College, Oxford, he has been elected to membership in the European Academy of Arts and Sciences (Academia Europaea), the Institut International de Philosophie, and several other learned academies. Having held visiting lectureships at Oxford, Constance, Salamanca, Munich, and Marburg, Professor Rescher has received six honorary degrees from universities on three continents. Author of some hundred books ranging over many areas of philosophy, over a dozen of them translated into other languages, he was awarded the Alexander von Humboldt Prize for Humanistic Scholarship in 1984. Includes the following: Volume 10, Studies in the History of Logic; Volume 11, Studies in the Philosophy of Science; Volume 12, Studies in Metaphysical Optimalism; Volume 13, Studies in Leibniz's Cosmology; Volume 14, Studies in Autobiography.

A unified treatment of conditionals based on epistemological principles rather than the semantical principles in vogue over recent decades. This book by distinguished philosopher Nicholas Rescher seeks to clarify the idea of what a conditional says by elucidating the information that is normally transmitted by its utterance. The result is a unified treatment of conditionals based on epistemological principles rather than the semantical principles in vogue over recent decades. This approach, argues Rescher, makes it easier to understand how conditionals actually function in our thought and discourse. In its concern with what language theorists call pragmatics--the study of the norms and principles governing our use of language in conveying information-- Conditionals steps beyond the limits of logic as traditionally understood and moves into the realm claimed by theorists of artificial intelligence as they try to simulate our actual information-processing practices. The book's treatment of counterfactuals essentially revives an epistemological approach proposed by F. P. Ramsey in the 1920s and developed by Rescher himself in the 1960s but since overshadowed by the now-dominant possible-worlds approach. Rescher argues that the increasingly evident liabilities of the possible-worlds strategy make a reappraisal of the older style of analysis both timely and desirable. As the book makes clear, an epistemological approach demonstrates that counterfactual reasoning, unlike inductive inference, is not a matter of abstract reasoning alone but one of good judgment and common sense.

On Certainty continues Rescher s longstanding practice of publishing occasional studies that form part of a wider program of investigation of the scope and limits of rational inquiry in the pursuit of understanding. And pragmatism forms a subtextual Leitmotiv of these essays, seeing that the linking idea at work throughout is that knowledge is a tool for the management of our theoretical and practical affairs, and that what we ask of it is serviceability for the uses we have in view."

Regression addresses what has come before; it is a matter of looking backward of retrospections? The motionless things of nature are generally forward-looking their problem is that of the question: Where do we go from here? It is primarily with intelligent beings that we ask: How did we get to where we now find ourselves? Regression and infinite regression in particular is thus a concept that has gained a greater prominence in the human sciences than in the sciences of nature. Argumentation to infinite regress has long been a favored instrument of philosophical dialectic. Philosophers have used it to disprove the positions they model to criticize. Infinite regresses, so they reason, are unrealizable: they cannot be completed so as to achieve some definitive result. And thereby anything that would engender an infinite regress is automatically made ineffective. Infinite Regress examines the theory of regression and includes information on the topics of vicious regress, innocuous regress, circularity regress, and propositional regress. Also discussed is the history of regression stemming from ancient times, to medieval times, to early modern history. Some of the other chapters in this book focus on world class philosophers including Immanuel Kant, Georg Wilhelm Friedrich Hegel, and Bertrand Russell. The book will play a significant role in theoretical philosophy as well as in social philosophy and the philosophy of mind.

Arabic contributions to medicine, mathematics, astronomy, and other fields have been extensively studied, yet Arabic logic has never been systematically investigated. In this book, Nicholas Rescher sheds new light on the major philosophical contribution of Arab logicians. He provides a historical account of the evolution of Arabic logic, from its inception in the early ninth century through the sixteenth century, when these tenets gained wide acceptance. The book also includes a bio-bibliography of 170 Arabic logicians, and a discussion of the place of each within the overall scheme of developments.

This is the third and final volume of A System of Pragmatic Idealism, a series that will synthesize the life's work of the philosopher Nicholas Rescher. Rescher's numerous books and articles, which address almost every major philosophical topic, reflect a unified approach: the combination of pragmatism and idealism characteristic of his thinking throughout his career. The three related but independently readable books of the series present Rescher's system as a whole. In combining leading ideas of European continental idealism and American pragmatism in a new way, Rescher has created an integrated philosophical position in which the central concepts of these two traditions become a coherent totality. The initial volume in the series was dedicated to epistemology, the philosophy of science, and the philosophy of nature, while the second dealt with issues of value theory, ethics, and practical philosophy. In Volume III Rescher examines the nature of philosophical inquiry itself, seeking to affirm the classical conception of philosophy as a significant problem-solving enterprise that draws on the whole range of human experience to attempt to resolve the "big questions." Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
