This is absolutely the best introduction to modern literary theory, and I have read them all! He introduces the theories in an historical narrative, explaining how and why they arose. He discusses the major figures in theory, and includes a valuable guide to further reading. His explanations of the abstruse and arcane world of literary theory are models of clarity and conciseness. I teach an introductory class on literary theory, and this is the book I use, chosen after carefully reviewing all available options.
