'This book by Duncan Pritchard is an excellent introduction to the theory of knowledge, as well as a useful resource for understanding Pritchard's own important view. Pritchard's treatment of the subject area is masterful, achieving a combination of clarity and efficiency that is rarely seen in philosophy.' - John Greco, Saint Louis University, USA 'An excellent overview of contemporary epistemology from the perspective of an established, prolific contributor to the field. It is informative, objective, and well argued, but also readable and engaging.' - Ernest Sosa, Rutgers University, USA
