Book excerpt: The main argument of this book is that most rhetorical theory defines rhetoric as its manifestations - speeches, essays, poems and so forth. It proposes that rhetoric be regarded as the social function that manages meaning - a function with many complex manifestations. The author develops a theoretical scheme to explain this concept and details principles for critical and pedagogical application of his theory. In the second part of the book, the author applies theory and critical principles to the complex and fragmented texts of popular culture - television programmes, science fiction, horror films, popular periodicals and novels - and to the arena of urban race relations.
