Suitable for courses in Critical Thinking, English Composition, Introduction to Logic, Philosophy, and Psychology, this text was written to give teachers and students a better and more comprehensive critical thinking text; one that presents an interdisciplinary, systematic, practical, and friendly approach to thinking—a valuable skill that can enlarge the students' ability to think through life. The Second Edition reflects the analyses, ideas, and support of the teachers, reviewers, editors, and students who contributed their feedback.
