QuoteReview:There are three reasons why this is a valuable book on fallacies: * It is an extensive application of logic, especially logical fallacies, to an area of study, namely, history. * It has the longest list of fallacies of any book I know about: 112 are listed in the index. This makes it useful as a reference book on fallacies. Because of its focus on historical reasoning, some of these fallacies are specific to history (which is one reason why there are so many!), but most can be generalized to other areas of thought. * It is a treasure trove of real examples drawn, of course, from the works of historians.Fischer, an historian rather than a logician, works with a broad conception of "fallacy" (which is another reason why there are so many!). As a result, some of the "fallacies" are more properly boobytraps or cognitive biases, but they are no less interesting or important for all that.The book categorizes historical fallacies into eleven broad categories, of which the following are examples: * Fallacies of Question-Framing: Many Questions, for example. * Fallacies of Semantical Distortion: Ambiguity, Amphiboly, Equivocation, among others. * Fallacies of Substantive Distraction: Includes the "ad" fallacies, such as Ad Hominem.Of special interest are the two categories Fallacies of Causation and Fallacies of False Analogy, which give the best and most thorough treatments of mistakes in reasoning about causation, and by analogy, that I've ever read. In these two chapters, Fischer goes beyond application to make real contributions to the theory of fallacies.In addition to being a rich reference source for fallacies and examples of them, Historians' Fallacies is intelligently written, and makes especially good reading for those interested in history. I hope that future historians and logicians will study this book carefully, with an eye to improving both fields.
