Ideally a logic text should encourage not only criticism of thinking, but critical thinking itself. To its great credit, ard Thinking does both. s Nicholas Rescher, University of Pittsburgh Mullen effectively combines logic, epistemology, and good old fashioned common sense. The dialogues and examples are telling; the explanations clear and to the point. The book articulates, defends, and exemplifies all the important features of 'hard thinking'. Many texts purport to aid in the teaching of thinking; this one will clearly succeed. s Harvey Siegel, University of Miami Not only does Mullen's text challenge students to do some hard thinking, but it explains why they should and it shows them how....[T]he text includes strong chapters on both traditional and modern formal logic. As a result, this book should prove suitable for a wide variety of courses. s Bruce Umbaugh, Webster University CONDITION â USED: Books sold are in GOOD or better condition.
