A Syllogisms Playbook: Using PLN for Deductive Logic

For more than two thousand years a study of deductive logic centered on the use of syllogisms as presented by Aristotle. In the twentieth century this was overshadowed by a symbolic logic that, while originally intended to discover a basis for mathematics, allowed new leaps forward in computer programming. However, the idea of examining the logic of an argument through the use of syllogisms has remained attractive as a starting point for beginning students. What was missing was a way of simplifying this study. Professor McFerran offers this in his adaptation of traditional material through the use of a postfix literal notation (PLN).
