Course Description (and Duration): 30 Weeks.  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 which they can be equivalent, and the seven rules for the validity of syllogisms. Each chapter explains challenging concepts in clear, concise language. 

Traditional Logic, Book II: Advanced Formal Logic, by Martin Cothran, is a continuation of Memoria Press’ Traditional Logic, Book I. It covers the four figures of the traditional syllogism, the three forms of rhetorical arguments (called enthymemes), the three kinds of hypothetical syllogisms, the four kinds of complex syllogisms, as well as relational

arguments. The book also includes a wealth of examples of arguments from the Bible, Lewis Carroll, Isaac Watts, St.Augustine, and Tertullian, as well as extended case studies of famous arguments throughout history, such as Rene Descartes’ famous enthymeme: “I think, therefore, I am”; C. S. Lewis’ disjunctive syllogism proving the deity of Christ; Plato’s hypothetical argument concerning the power of love; Christ’s conjunctive syllogism: “You cannot serve both God and mammon”; David Hume’s famous dilemma stating the problem of evil; the stoic Seneca’s justification of the virtuous life; and St. Thomas Aquinas’ cosmological argument for the existence of God.
