Striking out at the conception of criticism as restricted to mere opinion or ritual gesture, Northrop Frye wrote this magisterial work proceeding on the assumption that criticism is a structure of thought and knowledge in its own right. Employing examples of world literature from ancient times to the present, he provides a conceptual framework for the examination of literature. In four brilliant essays on historical, ethical, archetypical, and rhetorical criticism, he applies "scientific" method in an effort to change the character of criticism from the casual to the causal, from the random and intuitive to the systematic.
Harold Bloom contributes a fascinating and highly personal preface that examines Frye's mode of criticism and thought (as opposed to Frye's criticism itself) as being indispensable in the modern literary world.
