Our beliefs constitute a large part of our knowledge of the world. We have beliefs about objects, about culture, about the past, and about the future. We have beliefs about other people, and we believe that they have beliefs as well. We use beliefs to predict, to explain, to create, to console, to entertain. Some of our beliefs we call theories, and we are extraordinarily creative at constructing them. Theories of quantum mechanics, evolution, and relativity are examples. But so are theories about astrology, alien abduction, guardian angels, and reincarnation. All are products (with varying degrees of credibility) of fertile minds trying to find explanations for observed phenomena. In this book, Nils Nilsson examines beliefs: what they do for us, how we come to hold them, and how to evaluate them. We should evaluate our beliefs carefully, Nilsson points out, because they influence so many of our actions and decisions.Some of our beliefs are more strongly held than others, but all should be considered tentative and changeable. Nilsson shows that beliefs can be quantified by probability, and he describes networks of beliefs in which the probabilities of some beliefs affect the probabilities of others. He argues that we can evaluate our beliefs by adapting some of the practices of the scientific method and by consulting expert opinion. And he warns us about "belief traps"--holding onto beliefs that wouldn't survive critical evaluation. The best way to escape belief traps, he writes, is to expose our beliefs to the reasoned criticism of others.

    The arguement is developed by means of the notion of possible worlds and ranges over key problems including the nature of essence, trans-world identity, negative existential propositions, and the existence of unactual objects in other possible worlds. In the final chapters Professor Plantinga applies his logical theories to the elucidation of two problems in the philosophy of religion: the Problem of Evil and the Ontological Arguement. The first of these, the problem of reconciling the moral perfection and omnipotence of God with the existence of evil, can, he concludes, be resolved, and the second given a sound formulation. The book ends with an appendix on Quine's objection to quantified modal logic.

    This handsome new edition of Stanley Cavell's landmark text, first published 20 years ago, provides a new preface that discusses the reception and influence of his work, which occupies a unique niche between philosophy and literary studies.

    It is universally recognized as the standard English version of Aristotle. This revised edition contains the substance of the original translation, slightly emended in light of recent scholarship; three of the original versions have been replaced by new translations; and a new and enlarged selection of Fragments has been added. The aim of the translation remains the same: to make the surviving works of Aristotle readily accessible to English speaking readers.

    Basic Writings offers a full range of this profound and controversial thinker's writings in one volume, including:The Origin of the Work of ArtThe introduction to Being and TimeWhat Is Metaphysics?Letter on HumanismThe Question Concerning TechnologyThe Way to LanguageThe End of Philosophy

    It should prove a real boon to the student of Peirce." — The Modern SchoolmanCharles S. Peirce was a thinker of great originality and power. Although unpublished in his lifetime, he was recognized as an equal by such men as William James and John Dewey and, since his death in 1914, has come to the forefront of American philosophy. This volume, prepared by the Johnsonian Professor of Philosophy at Columbia University, formerly chairman of Columbia's philosophy department, is a carefully balanced exposition of Peirce's complete philosophical system as set forth in his own writings.The 28 chapters, in which appropriate sections of Peirce's work are interwoven into a brilliant selection that reveals his essential ideas, cover epistemology, phenomenology, cosmology, and scientific method, with especially interesting material on logic as the theory of signs, pure chance vs, pure law in the universe, symbolic logic, common sense, pragmatism (of which he was the founder), and ethics.Justus Buchler is author of Charles Peirce's Empiricism (1939), Philosophy: An Introduction (with J. H. Randall, Jr., 1942), and more recently, a series of books which form an ongoing philosophic structure: Toward a General Theory of Human Judgement (1951), Nature and Judgment (1855), and The Concept of Method (1961). It has been said of these volumes, "A fresh and vital system of ideas has been introduced into the world of contemporary philosophy." (Journal of Philosophy)."It is a very signal advantage to have this collection of Peirce's most important work within the covers of a single substantial volume. We should all be very grateful to Mr. Buchler." — John Laird, Philosophy

    Based on the new and much acclaimed two volume Cambridge edition of The Philosophical Writings of Descartes by Cottingham, Stoothoff, and Murdoch, this anthology of essential texts contains the most important and widely studied of those writings, including the Discourse and Meditations and substantial extracts from the Regulae, Optics, Principles, Objections and Replies, Comments on a Broadsheet, and Passions of the Soul.

    Inwood and Gerson maintain the standard of consistency and accuracy that distinguished their translations in the first edition, while regrouping some material into larger, more thematically connected passages. This edition is further enhanced by a new, more spacious page design.

    It will help students to think more clearly about how to form their moral beliefs in the wisest and most rational way. The basic approaches to metaethics and normative ethics are related to specific issues, particularly those of racism, education, and abortion. Written in a clear and concise way by an experienced textbook author, Ethics will also be of interest to the general reader.Unique features of the textbook: * boxed key ideas* Glossary of philosophical terms* Chapter summaries and study questions * Annotated further reading and Internet Web resourcesThere is an associated website for teachers and students at www.routledge.com/routledge/philosoph...

    In this lively and topical introduction, Wartenberg reveals a vibrant mode of philosophical inquiry that addresses concerns at the heart of the existence of every human being. Wartenberg uses classic films, novels, and plays to present the ideas of now-legendary Existentialist thinkers from Nietzsche and Camus to Sartre and Heidegger and to explore central concepts, including Freedom, Anxiety, and the Absurd. Special attention is paid to the views of Simone de Beauvoir and Franz Fanon, who use the theories of Existentialism to address gender and colonial oppression.

    It aims to reach students who have already done an introductory philosophy course.Topics covered include perception and reflection as grounds of knowledge, and the nature, structure, and varieties of knowledge. The character and scope of knowledge in the crucial realms of ethics, science and religion are also considered.Unique features of Epistemology: * Provides a comprehensive survey of basic concepts and major theories* Gives an up-to-date account of important developments in the field* Contains many lucid examples to support ideas* Cites key literature in an annotated bibliography.

    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.

    No one philosopher contributed more to this enterprise than Kant, whose Critique of Pure Reason (1781) shook the very foundations of the intellectual world. Kant argued that the basic principles of the natural sciences are imposed on reality by human sensibility and understanding, and thus that human beings are also free to impose their own free and rational agency on the world. This volume is the only systematic and comprehensive account of the full range of Kant's writings available, and the first major overview of his work to be published in more than a dozen years. An internationally recognized team of Kant scholars explore Kant's conceptual revolution in epistemology, metaphysics, philosophy of science, moral and political philosophy, aesthetics, and the philosophy of religion. The volume also traces the historical origins and consequences of Kant's work.

    This volume brings together some of the most influential contributions to the topic of free will during the past 50 years, as well as some notable recent work.

    Much of the book takes the form of a discussion between a teacher and his students. They propose various solutions to some mathematical problems and investigate the strengths and weaknesses of these solutions. Their discussion (which mirrors certain real developments in the history of mathematics) raises some philosophical problems and some problems about the nature of mathematical discovery or creativity. Imre Lakatos is concerned throughout to combat the classical picture of mathematical development as a steady accumulation of established truths. He shows that mathematics grows instead through a richer, more dramatic process of the successive improvement of creative hypotheses by attempts to 'prove' them and by criticism of these attempts: the logic of proofs and refutations.
