Nonsense is the best compilation and study of verbal logical fallacies available anywhere. It is a handbook of the myriad ways we go about being illogical--how we deceive others and ourselves, how we think and argue in ways that are disorderly, disorganized, or irrelevant. Nonsense is also a short course in nonmathematical logical thinking, especially important for students of philosophy and economics. A book of remarkable scholarship, Nonsense is unexpectedly relaxed, informal, and accessible.
