This volume of original essays assesses Nozick's analyses of knowledge and evidence and his approach to skepticism. Several of the contributors claim that Nozick has not succeeded in rebutting the skeptic; some offer fresh accounts of skepticism and its flaws; others criticize Nozick's externalist accounts of knowledge and evidence; still others welcome externalism but attempt to replace Nozick's accounts of knowledge and evidence with more plausible analyses.

explores the interaction between psychology and epistemology and addresses empirical questions about how we should arrive at our beliefs, and whether the processes by which we arrive at our beliefs are the ones by which we ought to arrive at our beliefs.

Epistemology has always been concerned with mental states, especially doxastic states such as belief, suspension of judgment, and the like. A significant part of epistemology is the attempt to evaluate, appraise, or criticize alternative procedures for the formation of belief and other doxastic attitudes. In addressing itself to doxastic states, epistemology has usually employed our everyday mental concepts and language. Occasionally it has tried to systematize or precise these mental categories, e.g., by introducing the notion of subjective probabilities. But this (...) is a minor refinement in our intuitive notion of degrees of confidence. What epistemology has not done—at least 20th century analytic epistemology hasn’t done it—is to seek help from experimental psychology in choosing its doxastic categories. Analytic epistemology has generally assumed that doxastic descriptions generated by casual and introspective thought are adequate for its purposes. (shrink)
