Introductory Logic: For Christian and Home Schools

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. First, students are introduced to propositional logic, logical operators, and truth tables, while reviewing and reapplying the concepts of validity, contradiction, consistency, and equivalence. Next they learn to construct formal proofs of validity by using basic rules to derive an argument's conclusions from its premises. Finally, students discover how they can use the technique of "truth trees" to determine consistency, self-contradiction, tautology, equivalence, and validity.
