Book excerpt: My impulse when I decided to collect into a single volume the essays on topics in logical theory and related subjects that I have written in the last fifteen years was to borrow from the title of a work by Sextus Empiricus, and call my collection "Against the Logicians." Although the essays address a variety of problems that interest me, the thread that runs through them is a scepticism about how logicians see things. So, the title appealed to me. However, I had second thoughts and chose instead a title of one of my own essays, "In Defense of Informal Logic", which emphasizes my support for other approaches. Although my criticisms of logical theory are designed to cut deeply, I do not want to be unresponsive to the needs that it is supposed to satisfy. However, my position that we have adequate resources for critically analyzing a particular argument and 00 not need a theory of argumentation, will not completely satisfy those who think that there is a need for it. So, I want them to know that I am taking their concerns seriously.

Book Synopsis Informal Logic by : Wayne Grennan

Download or read book Informal Logic written by Wayne Grennan. This book was released on 1997. Available in PDF, EPUB and Kindle. Book excerpt: Grennan bases his evaluation of arguments on two criteria: logical adequacy and pragmatic adequacy. He asserts that the common formal logic systems, while logically sound, are not very useful for evaluating everyday inferences, which are almost all deductively invalid as stated. Turning to informal logic, he points out that while more recent informal logic and critical thinking texts are superior in that their authors recognize the need to evaluate everyday arguments inductively, they typically cover only inductive fallacies, ignoring the inductively sound patterns frequently used in successful persuasion. To redress these problems, Grennan introduces a variety of additional inductive patterns. Concluding that informal logic texts do not encourage precision in evaluating arguments, Grennan proposes a new argument evaluation procedure that expresses judgments of inferential strength in terms of probabilities. Based on theories of Stephen Toulmin, Roderick Chisholm, and John Pollock, his proposed system allows for a more precise judgment of the persuasive force of arguments.

Book Synopsis Informal Logic by : Douglas N. Walton

Download or read book Informal Logic written by Douglas N. Walton. This book was released on 1989-07-28. Available in PDF, EPUB and Kindle. Book excerpt: This is an introductory guide to the basic principles of constructing good arguments and criticizing bad ones. It is nontechnical in its approach, and is based on 150 key examples, each discussed and evaluated in clear, illustrative detail. The author explains how errors, fallacies, and other key failures of argument occur. He shows how correct uses of argument are based on sound argument strategies for reasoned persuasion and critical questions for responding. Among the many subjects covered are: techniques of posing, replying to, and criticizing questions, forms of valid argument, relevance, appeals to emotion, personal attack, uses and abuses of expert opinion, problems in deploying statistics, loaded terms, equivocation, and arguments from analogy.

Book Synopsis Historical Foundations of Informal Logic by : Douglas Walton

Download or read book Historical Foundations of Informal Logic written by Douglas Walton. This book was released on 2016-12-05. Available in PDF, EPUB and Kindle. Book excerpt: In just the last twenty years there has arisen a strong interest, especially among teachers of logic at the universities, in teaching techniques of applied logical reasoning and critical thinking. Many universities are now stressing these skills at an introductory level, and to meet the need, informal logic has begun to form and grow as a discipline in its own right. Like all subjects, it helps us to understand it if we can situate it in a context of historical development. This collection of essays provides the readings required to understand the development of a subject whose historical origins have been so far little studied. Many of the chapters are written by scholars in philosophy and speech communication who are themselves leading contributors to the subject, and their contemporary views throw light on how these earlier writers have influenced their thinking. This dimension gives an added interest to the essays, and indicates the way informal logic is currently evolving and seeking out its ancient historical origins.
