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)

What is "critical thinking"? Is it something that is general across disciplines, or a different entity in each discipline? Should we teach it, and if so, why? These are the kinds of questions Harvey Siegel addresses in his book on Educating Reason. As is true in any book of this kind, some questions are answered better than others.

Musclebuilding for Strength in Critical Thinking.

Teaching Critical Thinking in the "Strong" Sense: A Focus On Self-Deception, World Views, and a Dialectical Mode of Analysis.

Many social scientists and philosophers have counted themselves moral relativists in some sense or other. We cannot deal with all the various views which are properly called forms of “moral relativism”; so I propose to explain a form of moral relativism which seems to me an interesting, and somewhat plausible theory. This theory comprises the following three affirmations: The basic moral principles of different individuals or groups sometimes are, or can be, in some important sense conflicting. When there is such (...) fundamental conflict of basic principles or standards, there is either always, or at least sometimes, no way to show that one view is better justified even in the presence of ideally complete factual information; in that sense the principles are equally justified or “valid.” But there is a sense in which a particular moral belief may be mistaken or unjustified, if it is a misapplication of the basic principles of the individual or group, e.g., if the basic principles plus statements of known or knowable facts entail a moral proposition incompatible with it. As stated, moral relativism could be true even though in fact, accidentally, all individuals agree in their basic moral principles. (shrink)

The main currently unsolved problem in the theory of argumentation concerns the function of logic in argumentation and reasoning. The traditional view simply identified logic with the theory of reasoning. This view is still being echoed in older textbooks of formal logic. In a different variant, the same view is even codified in the ordinary usage of words such as ‘logic’, ‘deduction’, ‘inference’, etc. For each actual occurrence of these terms in textbooks of formal logic, there are hundreds of uses (...) of the same idioms to describe the feats of real or fictional detectives. I have called the idea reflected by this usage the “Sherlock Holmes conception of logic and deduction.” In the history of science, we find no less a thinker than Sir Isaac Newton describing his experimental method as one of analysis or resolution and claiming to have “deduced” at least some of his laws from the “phenomena.”.

This is a textbook for teachers that demonstrates how philosophical thinking can be used in teaching children.

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

Reichenbach's well-known distinction between the context of discovery and the context of justification has recently come under attack from several quarters. In this paper I attempt to reconsider the distinction and evaluate various recent criticisms of it. These criticisms fall into two main groups: those which directly challenge Reichenbach's distinction; and those which (I argue) indirectly but no less seriously challenge that distinction by rejecting the related distinction between psychology and epistemology, and defending the "naturalizing" of epistemology. I argue that (...) these recent criticisms fail, and that the distinction remains an important conceptual tool necessary for an adequate understanding of the way in which scientific claims purport to appropriately portray our natural environment.

Hempel and Oppenheim, in their paper 'The Logic of Explanation', have offered an analysis of the notion of scientific explanation. The present paper advances considerations in the light of which their analysis seems inadequate. In particular, several theorems are proved with roughly the following content: between almost any theory and almost any singular sentence, certain relations of explainability hold.

The object of this paper is to show why recent research in the psychology of deductive and probabilistic reasoning does not have.
