Renaissance logician, philosopher, humanist, and teacher, Peter Ramus (1515-72) is best known for his attack on Aristotelian logic, his radical pedagogical theories, and his new interpretation for the canon of rhetoric. His work, published in Latin and translated into many languages, has influenced the study of Renaissance literature, rhetoric, education, logic, and—more recently—media studies. Considered the most important work of Walter Ong's career, Ramus, Method, and the Decay of Dialogue is an elegant review of the history of Ramist scholarship and Ramus's quarrels with Aristotle. A key influence on Marshall McLuhan, with whom Ong enjoys the status of honorary guru among technophiles, this challenging study remains the most detailed account of Ramus's method ever published. Out of print for more than a decade, this book—with a new foreword by Adrian Johns—is a canonical text for enthusiasts of media, Renaissance literature, and intellectual history.
