General Description

Traditional Logic, Book II: Advanced Formal Logic by Martin Cothran is a continuation of Memoria Press's Traditional Logic 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, and 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 René Descartes' famous enthymeme, "I think, therefore, I am"; C.S. Lewis's 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.
