Manifest Rationality

Reviews / Votes

"Manifest Rationality is an important book, because it presents a detailed assessment of the way in which informal logic, as opposed to formal deductive logic, deals with the problems which a theory of argument poses, and because it attempts to develop the informal logic approach by basing it, more consistently than has been done so far, on a pragmatic and dialectical conception of argument. A major value of the book consists in providing a clear and comprehensive overview of the concerns of informal logic. But, above all, of course, the book's value lies in bringing informal logic up to date by incorporating into it the dialectical and pragmatic dimensions which modern argumentation theories such as formal dialectics and pragma-dialectics have shown to be crucial to the study of argument....For specialists in the field and advanced students of argumentation theory the book will be of great interest."
-Argumentation

"In this ambitious work, there are many matters of detail to inspire interest....For anyone who is interested in real and realistic arguments, and current theorizing about them Manifest Rationality will be an important book to study."
-History & Philosophy

"Johnson's thorough review of twentieth century developments in informal logic and argument theory, development of a more pragmatic theory of argument, and advocacy of a more dialogically-engaged argumentation pedagogy make Manifest Rationality worth the investment."
