Abstract

The subject of this book is epistemology. Epistemology is the theory of knowledge, the study of the nature, sources, and limitations of knowledge and justification. In studying the nature of knowledge and justification, theorists typically try to delineate the conditions that must be met for a given person to know, or justifiably believe, that a given proposition is true. That is, they offer analyses of knowledge and justification. In this introduction, we will briefly describe the task of analysis, and review some of the ways people have understood epistemic concepts. We will also outline some of the difficulties theorists have confronted while working out what may be known.
