For two decades, students and instructors have relied on award-winning author Craig Smith’s detailed description and analysis of rhetorical theories and the historical contexts for major thinkers who advanced them. He employs key themes from important philosophical schools in this well-researched chronicle of rhetoric and human consciousness. One is that rhetoric is a response to uncertainty. The modern philosophers, like the naturalists of ancient Greece and the Scholastics who preceded them, tried to end uncertainty by combining the discoveries of science and psychology with rationalism. Their aim was progress and a consensus among experts as to what truth is. However, where modernism proved ineffective, rhetoric was revived to fill the breach. Another significant theme is that different conceptions of human consciousness lead to different theories of rhetoric, and for every major school of thought, another school of thought forms in reaction. Classic and contemporary examples demonstrate the usefulness of rhetorical theory, especially its ability to inform and guide. By providing probes for rhetorical criticism, discussions also demonstrate that rhetorical criticism illustrates, verifies, and refines rhetorical theory. Thus, the synergistic relationship between theory and criticism in rhetoric is no different than in other arts: Theory informs practice; analysis of successful practice refines theory. Smith’s absorbing study has been expanded to include thorough treatments of rhetoric in the Romantic Era, feminist and queer theory, and historical context for the creation of rhetorical theory and its use in public address.
