Richards, Ernesto Grassi, Chaïm Perelman and Lucie Olbrechts-Tyteca, Stephen Toulmin, Richard Weaver, Kenneth Burke, Jürgen Habermas, bell hooks, Jean Baudrillard, and Michel Foucault.

The concise explanations of complex concepts are clear, engaging, insightful, and highly accessible, serving as an excellent primer for reading the major works of these scholars. The critical commentary is carefully chosen to highlight implications and to place the theories within a broader rhetorical context. Each chapter ends with a complete bibliography of works by the theorists.
