LOGIC: THE ESSENTIALS concentrates on the fundaments of introductory logic. Practical in orientation and content, Essentials is loaded with class-tested, proven practice exercises. The book is tailored to address the needs of many of today's instructors who are challenged by time constraints but yet want to instill in their students a solid grasp of basic logical principles and the requisite skill to apply them in everyday life. This new text is based on the classic and bestselling textbook, A Concise Introduction to Logic, and nearly all of the exercises in the correlative chapters, so central to the effectiveness of that text, have been retained to ensure more than enough practice for students to master the central concepts. The text focuses largely on deductive logic, but it contains sufficient treatment of induction to provide a solid footing for informal fallacies. The result is a contemporary approach--more focused, more practical, less theoretical--built on a tradition of precise, elegant, and clear presentation of the subject matter of logic, both formal and informal.

"Previews" sections use familiar examples to connect logical concepts to students' everyday lives. Key terms in boldface type are defined in marginal boxes throughout the text for easy studying and review.
