The Theory Of Knowledge

Epistemology or the theory of knowledge is one of the cornerstones of analytic philosophy, and this book provides a clear and accessible introduction to the subject. It discusses some of the main theories of justification, including foundationalism, coherentism, reliabilism, and virtue epistemology. Other topics include the Gettier problem, internalism and externalism, skepticism, the problem of epistemic circularity, the problem of the criterion, a priori knowledge, and naturalized epistemology. Intended primarily for students taking a first class in epistemology, this lucid and well-written text would also provide an excellent introduction for anyone interested in knowing more about this important area of philosophy.

In this important new text, Keith Lehrer introduces students to the major traditional and contemporary accounts of knowing. Beginning with the accepted definition of knowledge as justified true belief, Lehrer explores the truth, belief and justification conditions on the way to a thorough examination of foundation theories of knowledge, externalism and naturalized epistemologies, internalism and modern coherence theories as well as recent reliabilist and causal theories. Lehrer gives all views careful examination and concludes that external factors must be matched by appropriate internal ones to yield knowledge. Readers of Professor Lehrer's earlier book Knowledge will want to know that this text adopts the framework of that classic text. But Theory of Knowledge is a completely rewritten and updated version of that book that has been simplified throughout for student use.

An Introduction to the Theory of Knowledge, 2nd Edition guides the reader through the key issues and debates in contemporary epistemology. Lucid, comprehensive and accessible, it is an ideal textbook for students who are new to the subject and for university undergraduates. The book is divided into five parts. Part I discusses the concept of knowledge and distinguishes between different types of knowledge. Part II surveys the sources of knowledge, considering both a priori and a posteriori knowledge. Parts III and IV provide an in-depth discussion of justification and scepticism. The final part of the book examines our alleged knowledge of the past, other minds, morality and God. In this extensively revised second edition there are expanded sections on epistemic luck, social epistemology and contextualism, and there are new sections on the contemporary debates concerning the lottery paradox, pragmatic encroachment, peer disagreement, safety, sensitivity and virtue epistemology. Engaging examples are used throughout the book, many taken from literature and the cinema. Complex issues, such as those concerning the private language argument, non-conceptual content, and the new riddle of induction, are explained in a clear and accessible way. This textbook is an invaluable guide to contemporary epistemology.

In a letter of 1932, Karl Popper described Die beiden Grundprobleme der Erkenntnistheorie – The Two Fundamental Problems of the Theory of Knowledge – as ‘...a child of crises, above all of ...the crisis of physics.’ Finally available in English, it is a major contribution to the philosophy of science, epistemology and twentieth century philosophy generally. The two fundamental problems of knowledge that lie at the centre of the book are the problem of induction, that although we are able to observe only a limited number of particular events, science nevertheless advances unrestricted universal statements; and the problem of demarcation, which asks for a separating line between empirical science and non-science. Popper seeks to solve these two basic problems with his celebrated theory of falsifiability, arguing that the inferences made in science are not inductive but deductive; science does not start with observations and proceed to generalise them but with problems, which it attacks with bold conjectures. The Two Fundamental Problems of the Theory of Knowledge is essential reading for anyone interested in Karl Popper, in the history and philosophy of science, and in the methods and theories of science itself.

Theory of Knowledge gives us a picture of one of the great minds of the twentieth century at work. It is possible to see the unsolved problems left without disguise or evasion. Historically, it is invaluable to our understanding of both Russell's own thought and his relationship with Wittgenstein.

Guided by the founding ideas of American pragmatism, Epistemology provides a clear example of the basic concepts involved in knowledge acquisition and explains the principles at work in the development of rational inquiry. It examines how these principles analyze the course of scientific progress and how the development of scientific inquiry inevitably encounters certain natural disasters. At the center of the book's deliberations there lies not only the potential for scientific progress but also the limit of science as well. This comprehensive introduction to the theory of knowledge addresses a myriad of topics, including the critique of skepticism, the nature of rationality, the possibility of science for extraterrestrial intelligences, and the prospect of insoluble issues in science.

An introduction to contemporary epistemology, which utilizes traditional methods of epistemological inquiry in the context of contemporary debates about the definition, sources and limits of human knowledge. The authors relate epistemology to work in cognitive science and defend a plausible version of explationism regarding epistemological method.
