Unwavering in its fundamental commitment to today's students and their typical inexperience in rigorous logical analysis, Robert Johnson's A LOGIC BOOK is unparalleled in its ability to make logic simple, if not entertaining. After two chapters on basic concepts-argument, deductive validity, inductive strength, truth of premises-the text presents two different deductive systems, Categorical Logic and Truth-Functional Logic. A chapter on Formal Deduction is then followed by chapters on Inductive Logic and Informal Fallacies. The book culminates in a clear presentation of a strategy for evaluating lengthy arguments. Filled with timely examples and exercises drawn from popular culture, this book is an invitation to logic for even the most apprehensive students.
