The Power of Logic

The Power of Logic, 6th Edition, by Frances Howard-Snyder, is an introductory logic textbook designed to help students and instructors master systematic reasoning. Published by McGraw-Hill Higher Education with a 2020 copyright, the text provides a structured introduction to three major areas: informal logic, traditional categorical logic, and modern symbolic logic.

The textbook combines a direct writing style with engaging examples and challenging exercises that reinforce key concepts. Early chapters focus on basic logical ideas, techniques for identifying arguments, the interaction between logic and language, and common informal fallacies. The material then progresses to classical categorical logic, analyzing categorical statements and categorical syllogisms.

The final chapters cover formal symbolic methods and empirical reasoning, including truth tables, statement logic proofs, predicate logic, and inductive logic. This comprehensive sequence makes the book an effective primary resource for introductory undergraduate philosophy and logic courses requiring thorough coverage of informal and formal logical systems.
