We are pleased to publish this WSIA edition of Trudy’s Govier’s seminal volume, Problems in Argument Analysis and Evaluation. Originally published in 1987 by Foris Publications, this was a pioneering work that played a major role in establishing argumentation theory as a discipline. Today, it is as relevant to the field as when it first appeared, with discussions of questions and issues that remain central to the study of argument. It has defined the main approaches to many of those issues (...) and guided the ways in which we might respond to them. From this foundation, it sets the stage for further investigations and emerging research. This is a second edition of the book that is corrected and updated by the author, with new prefaces to each chapter. (shrink)

The book also comes with an exhaustive array of study aids that enable the reader to monitor and enhance the learning process.

There was a long tradition in philosophy according to which good reasoning had to be deductively valid. However, that tradition began to be questioned in the 1960’s, and is now thoroughly discredited. What caused its downfall was the recognition that many familiar kinds of reasoning are not deductively valid, but clearly confer justification on their conclusions. Here are some simple examples.

Mr. Wellman’s highly original contribution to the relatively new field of justification in ethics consists of characterizing the different ways in which ethical statements can be challenged and showing how each sort of challenge can be met by an appropriate response, enabling reasonable men to appropriately discuss or reflect on ethical issues. In developing his unique, systematic, methodology of ethics, Mr. Wellman has, first, rigorously reviewed and refuted the main arguments for the view of the nature of all reasoning as (...) deductive and, second, convincingly presented arguments for the existence of nondeductive evidences in ethics. Mr. Wellman’s broad definition of reasoning and his rejection of the identification of justification with reasoning reveals new dimensions of justification which will have wide implications in other areas of human speculation.

Conductive Arguments are held to be defeasible, non-conclusive, and neither inductive nor deductive (Blair and Johnson in Conductive argument: An overlooked type of defeasible reasoning. College, London, 2011). Of the different kinds of Conductive Arguments, I am concerned only with those for which it is claimed that countervailing considerations detract from the support for the conclusion, complimentary to the positive reasons increasing that support. Here’s an example from Wellman (Challenge and response: justification in ethics. Southern Illinois University Press, Chicago, 1971): (...) Although your lawn needs cutting, you ought to take your son to the movies because the picture is ideal for children and will be gone by tomorrow. (1971: 57) I argue that Conductive Arguments are not possible—the “ought” conclusion only holds if countervailing considerations are nullified. (shrink)
