In this study, Laurence BonJour introduces the serious philosophy student to the history and concepts of epistemology, while simultaneously challenging them to take an active part in its ongoing debates. The text reflects BonJour's conviction that the place to start any discussion of the theories of knowledge is with the classical problems, beginning with and centred around Descartes. Only after the groundwork for understanding epistemology is laid does BonJour move on to the more contemporary revolutions against the classical approach. This volume should be of use to those on introductory-level epistemology courses or, supplemented by appropriate readings, an upper-level epistemology class offered in many philosophy departments. It is not, however, a simple reader of the different theories of knowledge. It aims to encourage students to think independently about the various epistemological approaches presented in the text and form their own conclusions.
