For the Love of Truth
The complete 18-chapter course in Philalethic Logic — from the philosophical foundations of truth and belief through quantified claims, negation, truth-tree validation, and direct and compound modal reasoning, with an informal fallacy woven into nearly every chapter.
Teacher & Parent Supplement
Teaching notes, full answer keys, and gradable quizzes for every chapter — written for a parent or teacher who has never studied formal logic. Includes a suggested 34-week pacing guide.
Student Workbook
One additional practice lab per chapter — fresh problems in the same style and difficulty as the text's own exercises, for independent practice after each lesson.
Student Workbook Answer Key
Full worked answers to every practice lab in the Student Workbook — ideal for independent learners or for parents checking work at home.
