Socratic Logic

Subtitled A Logic Text Using Socratic Method, Platonic Questions and Aristotelian Principles and published by St. Augustine's Press, this is a full textbook of classical Aristotelian logic: terms, propositions, syllogisms and fallacies, with exercises. Kreeft wrote it as an alternative to symbolic logic, arguing that the older logic is better suited to ordinary language and to thinking about philosophical questions. It has gone through several editions.
