Douglas N. Walton is Professor of Philosophy at the University of Winnipeg, Manitoba, Canada.

"Walton has done an excellent job of placing argument in the context of dialogue and relating it to other concepts that are significant determinants of the adequacy of both the process by which conclusions involving disputed issues are reached and the conclusions themselves. He provides a truly comprehensive examination of what has come to be called 'practical argument.' The book is an intellectually rich exploration of the many facets of this important topic. The author carefully articulates his reservations concerning past treatments of practical argument and then demonstrates how the view he espouses overcomes many of the deficiencies noted." — Dennis S. Gouran, Pennsylvania State University
