Fundamentals of Critical Argumentation presents the basic tools for the identification, analysis, and evaluation of common arguments for beginners. The book teaches by using examples of arguments in dialogues, both in the text itself and in the exercises. Examples of controversial legal, political, and ethical arguments are analyzed. Illustrating the most common kinds of arguments, the book also explains how to evaluate each kind by critical questioning. Douglas Walton shows how arguments can be reasonable under the right dialogue conditions by using critical questions to evaluate them. The book teaches by example, both in the text itself and in exercises, but it is based on methods that have been developed through the author's thirty years of research in argumentation studies.

The book provides a historical (with an outline of the history of the concept of truth from antiquity to our time) and systematic exposition of the semantic theory of truth formulated by Alfred Tarski in the 1930s. This theory became famous very soon and inspired logicians and philosophers. It has two different, but interconnected aspects: formal-logical and philosophical. The book deals with both, but it is intended mostly as a philosophical monograph. It explains Tarski’s motivation and presents discussions about his ideas (pro and contra) as well as points out various applications of the semantic theory of truth to philosophical problems (truth-criteria, realism and anti-realism, future contingents or the concept of correspondence between language and reality).

This dictionary results from the titanic work by Rev. James Wood who collected quotations from ancient and modern English and foreign sources and put them in alphabetic order. The dictionary contains phrases, mottoes, maxims, proverbs, definitions, aphorisms, and sayings of different prominent people.

This elucidation and defense of naturalism argues that an uncompromising secular orientation is the best framework for the search for meaning and interprets religion in purely naturalistic terms. Part One seeks to demonstrate that religious symbols arise from facts about human beings and the societies in which they live, specifically our needs, fears, and aspirations. Part Two examines arguments for and against naturalism, including the defenses of naturalism by Sidney Hook, Ernest Nagel, Antony Flew, and critical reactions to their views. The forceful and rigorously analytical case made by Jean Hampton against naturalism is also examined, resulting in a clarification of the substantial and sound methodological grounds for naturalism and atheism. Part Three considers the strongest intellectual challenge to secularism and naturalism, namely that of Ludwig Wittgenstein and some of his followers - Norman Malcolm, D. Z. Phillips, Hilary Putnam, Rush Rhees, and Peter Winch. Nielsen concludes that none of these critiques diminish the cogency and viability of naturalism as the most reasonable basis for viewing our world today.
