Where do you go in logic after you've mastered beginning logic? Intermediate Logic by James Nance takes students and parents to the next levels. This text is an excellent follow-up to Wilson and Nance's Introductory Logic in the Mars Hill Series. Together they can constitute a full, one-year course in logic. Covering topics in logic too often reserved for a college course, this text simplifies formal proofs and truth trees for propositional logic for the eighth grader and up.
