“One of the most careful and intensive among the introductory texts that can be used with a wide range of students. It builds remarkably sophisticated technical skills, a good sense of the nature of a formal system, and a solid and extensive background for more advanced work in logic. . . . The emphasis throughout is on natural deduction derivations, and the text’s deductive systems are its greatest strength. Lemmon’s unusual procedure of presenting derivations before truth tables is very effective.”
