• 1. Truth ; 2. Predicates and Subjects ; 3. What is a Connector? ; 4. Forms of Argument ; 5. The Science of Logic ; 6. When is a Syllogism not a Syllogism?

Besides providing fresh discussions of many well-known pieces of ancient logical doctrine, Barnes discovers and follows several untrodden paths of research that sometimes lead him very far form the familiar roads. This he can do, often very convincingly, thanks to his complete control over an impressive wealth of primary sources. The book thus enriches the received canon of ancient logical texts, giving voice to several minor figures. In many of its analyses and interpretations, Barnes's book reveals itself as an outstanding example of lucid philosophical thinking. No doubt, it will long continue to inspire and stimulate anyone wishing to think seriously about ancient logic.
