A logic course for all ages but designed for use as young as 7th grade, Traditional Logic is an in-depth study of the classical syllogism. Along with a basic understanding of the Christian theory of knowledge, the text presents the four kinds of logical statements, the four ways propositions can be opposed, the three ways in which they can be equivalent, and the seven rules for the validity of syllogisms. This comprehensive but easy-to-use course includes both text and key and can be used as either a one-semester or one-year course. Non-consumable. Designed specifically for the teacher with no logic background. Brief but comprehensive explanations of each lesson are followed by well-structured daily exercises.

Lewis' "trilemma"; St. Thomas Aquinas on the existence of God; David Hume on the problem of evil; and others from Augustine, Shakespeare, Plato, Seneca, Tertullian, Lewis Carroll, and the Bible. 4 Easy-to-use format; day-by-day, self-explanatory exercises; simple explanations of concepts.
