Vincent Leitch 
Theory Matters [PDF ebook] 

First Published in 2003. In this book on what theory means today, the general editor of the Norton Anthology of Criticism and Theory explores how theory has altered the way the humanities do business. Theory got personal, went global, became popular, and in the process has changed everything we thought we knew about intellectual life. One of the most adroit and perceptive observers of the critical scene, Vincent Leitch offers these engaging snapshots to show how theory is at work. This is an utterly readable little book by one of our best historians on the theoretical turn that over the past thirty years has so powerfully changed the academy.
