From the back cover: "Ever since Plato, philosophers have faced one central question: What is the scope and nature of human knowledge? In this volume the distinguished philosopher Ernest Sosa has collected his essays on this subject written over a period of twenty-five years. All the major topics of contemporary epistemology are covered: the nature of propositional knowledge, externalism versus internalism, foundationalism versus coherentism, and the problem of the criterion. The resulting book is a valuable resource for scholars and can (...) serve as a textbook for graduate seminars in epistemology.". (shrink)

Nozick analyzes fundamental issues, such as the identity of the self, knowledge and skepticism, free will, the foundations of ethics, and the meaning of life.

In this companion volume to Warrant: The Current Debate, Plantinga develops an original approach to the question of epistemic warrant; that is what turns true belief into knowledge. He argues that what is crucial to warrant is the proper functioning of one's cognitive faculties in the right kind of cognitive environment.

Reliabilist theories propose to analyse epistemic justification in terms of reliability. This paper argues that if we pay attention to the details of probability theory we find that there is no concept of reliability that can possibly play the role required by reliabilist theories. A distinction is drawn between the general reliability of a process and the single case reliability of an individual belief, And it is argued that neither notion can serve the reliabilist adequately.

According to a simple version of the reliability theory of epistemic justification, a belief is justified if and only if the process leading to that belief is reliable. The idea behind this theory is simple and attractive. There are a variety of mental or cognitive processes that result in beliefs. Some of these processes are reliable—they generally yield true beliefs—and the beliefs they produce are justified. Other processes are unreliable and the beliefs they produce are unjustified. So, for example, reliable (...) processes such as perception and memory yield justified beliefs while an unreliable process such as wishful thinking—believing something as a result of wishing that it is true—yields unjustified beliefs.

In Knowledge and Belief, Frederick Schmitt explores the nature and value of knowledge and justified belief through an examination of the dispute between epistemological internalism and externalism. Knowledge and justified belief are naturally viewed as belief of a sort likely to be true--an externalist view. It is also intuitive, however, to view them as an internal matter; justification must be accessible to the subject or constituted by the subject's epistemic perspective. The author argues against the view that internalism is the (...) historically dominant epistemology by examining closely the epistemological principles that underlie the treatment of skepticism in Plato, the Academic and Pyrrhonian skeptics, Descartes and Hume. Schmitt develops a sustained, detailed argument against many forms of internalism in favor of a reliabilist/externalist epistemology. His version of reliabilism, though strictly externalist, accommodates and explains the most durable intuitions alleged to support internalism. Knowledge and Belief assumes no knowledge of epistemology or its history. Readers of philosophy will find this an excellent introduction to ancient and modern epistemology; this systematic study of the internalist and externalist debate is the first of its kind. (shrink)

In epistemology, “contextualism” denotes a wide variety of more-or-less closely related positions according to which the issues of knowledge or justification are somehow relative to context. I will proceed by first explicating the position I call contextualism, and distinguishing that position from some closely related positions in epistemology, some of which sometimes also go by the name of “contextualism”. I’ll then present and answer what seems to many the most pressing of the objections to contextualism as I construe it, and (...) also indicate some of the main positive motivations for accepting the view. Among the epistemologists I’ve spoken with who have an opinion on the matter, I think it’s fair to say a majority reject contextualism. However, the resistance has to this point been largely underground, with little by way of sustained arguments against contextualism appearing in the journals,[i] though I have begun to see various papers in manuscript form which are critical of contextualism. Here, I’ll respond the criticism of contextualism that, in my travels, I have found to be the most pervasive in producing suspicion about the view. (shrink)

In this paper, I delineate two major problems facing reliabilist approaches in epistemology. I argue that Alvin Goodman's (1986) position fails to solve either problem. I then suggest an alternative reliabilist approach that ties truth-ratio assessments to particular, well-specified cognitive tasks. I claim that a well-specified cognitive task is an empirical hypothesis about a system that involves the specification of input and output types and nomic correlations (including statistical correlations) that underlie the system's performance. On my approach, one characterizes processes (...) by reference to the system's dispositions across the situations consistent with the task. Characterization is best understood as revealing a strategy or a set of strategies for generating outputs from inputs relying on certain nomic correlations associated with the task. (shrink)
