In this book and in its sequels, Warrant and Proper Function and Warranted Christian Belief, I examine the nature of epistemic warrant, that quantity, enough of which distinguishes knowledge from mere true belief. Contemporary epistemologists seldom focus attention on the nature of warrant; and when they do, they display deplorable diversity: some claim that what turns true belief into knowledge is a matter of epistemic dutifulness, others that it goes by coherence, and still others that it is conferred by reliability.

In this book and in its sequels, Warrant and Proper Function and Warranted Christian Belief, I examine the nature of epistemic warrant, that quantity, enough of which distinguishes knowledge from mere true belief. Contemporary epistemologists seldom focus attention on the nature of warrant; and when they do, they display deplorable diversity: some claim that what turns true belief into knowledge is a matter of epistemic dutifulness, others that it goes by coherence, and still others that it is conferred by reliability. I shall argue that none of these claims is correct, and (in Warrant and Proper Function) suggest a more satisfactory alternative. In the present book, I survey current contributions to the discussion of warrant and neighboring issues. I begin with internalism, looking first at the carefully crafted foundationalist internalism of Roderick Chisholm (Chs. 2 and 3). To better understand Chisholm and other internalists, however, I first make a preliminary excursus (Ch 1) into the classical internalism of Descartes, Locke, and others. After Chisholmian internalism, I turn to coherentism, which for classificatory purposes I take as a form of internalism. In the next three chapters, I consider coherentism taken generally (Ch. 4), the specific version of coherentism developed by Laurence BonJour (Ch. 5), and contemporary Bayesian versions of coherentism (Chs. 6 and 7). Next (Ch. 8), there is the more attenuated internalism of John Pollock, which I see as a transition from internalism to externalism. Finally, I examine the reliabilist and externalist views of William Alston, Fred Dretske, and Alvin Goldman (Ch. 9), and close with a preview of Warrant and Proper Function (Ch. 10).
