Product Description

Logic is the art of reasoning well - of learning to think God's thoughts after Him. In this book, James Nance builds on the foundation of Introductory Logic for Christian and Home Schools to help students explore the more challenging terrain of formal, propositional logic.

This Answer Key provides answers to all of the standard student text exercises. Also included are answers and examples for selected exercises in the "Additional Exercises" section found at the end of each lesson. Required for course.
