What is the main conflict in Beginning Theory: An Introduction to Literary and Cultural Theory by Peter Barry?

There isn't a conflicy in a fictional sense. "Beginning Theory" is detailed and specific enough to provide ready reference to the subject matter. For example, a reader who wants to know how a stylistic critic differs from a post-structuralist critic can find both identified by name and page number on the Contents page. Barry's literary critiques at the end of each chapter illustrate specific, practical examples of how that literary theory can be applied. This text is an excellent learning tool for a beginning or advanced student of literary and cultural theory. It is presented in an organized and well-defined manner. Barry's writing is clear, concise and informative, providing useful, relevant, yet not excessive or extraneous knowledge about the history and styles of literary criticism.
