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.
