This exciting new edition of the classic Contemporary Theories of Knowledge has been significantly updated to include analyses of the recent literature in epistemology. In addition, a new case is made for the strong connection between epistemology and artificial intelligence, as Pollock and Cruz argue that a necessary condition for the correctness of any epistemological theory is that it be possible to build an implemented artificial intelligence system on the basis of it. Like the first edition, Contemporary Theories of Knowledge, Second Edition is an excellent teaching tool, introducing the reader to the fundamental issues and approaches in the field of epistemology.

Providing a clear and accessible introduction to epistemology or the theory of knowledge, this book discusses some of the main theories of justification, including foundationalism, coherentism, reliabilism, and virtue 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.

This textbook introduces the concepts and theories central for understanding the nature of knowledge. It is aimed at students who have already done an introductory course. Epistemology, or the theory of knowledge, is concerned about how we know what we do, what justifies us in believing what we do, and what standards of evidence we should use in seeking truths about the world of human experience. The author's approach draws the reader into the subfields and theories of the subject, guided by key concrete examples. Major topics covered include perception and reflection as grounds of knowledge, the nature, structure, and varieties of knowledge, and the character and scope of knowledge in the crucial realms of ethics, science and religion.
