Sweet Reasonis an introductory text for courses on modern logic unlike any other. The basic rudiments of formal and informal logical are here, all clearly described. Further, it focuses students on the real world, where the discipline of logic adds substance and meaning to all kinds of human discourse. Everything from puzzles, paradoxes, and mathematical proofs to campaign debate excerpts, government regulations, and cartoons are used to show how logic is put to work by philosophers, mathematicians, advertisers, computer scientists, politicians, and others. As the book alternately discusses, instructs, questions, teases, and challenges, readers will find themselves: 1) absorbing the fundamentals of the discipline, 2) becoming fluent in thte language of logic, 3) understanding how logic works in the real world, 4) enjoying logic's ability to entertain, surprise, subvert, and enlighten.
