"Man He made to serve Him wittily," said Thomas More in Robert Bolt's A Man for All Seasons, "in the tangle of his mind." To serve God wittily requires an orderly mind, one capable of parsing through truths and falsehoods, able to string together arguments. Thus, the trivium endures: grammar, rhetoric, and logic.

To discuss teaching logic to high school students, we welcome to the podcast Mark Grannis, Heights teacher, attorney, father, and author of The Reasonable Person: Traditional Logic for Modern Life. In this episode, Mr. Grannis discusses what logic is, why it matters today, and how to teach it. Given man's nature as a rational animal, Mark argues that the study of logic—what he refers to as the art and science of sound reasoning—can improve the daily lives of everyone, regardless of his professional or academic path. Moreover, as social animals, Mark explains how logic can be a powerful means to attaining consensus in the public arena.

In a world in which thinking has become an increasingly outsourced ability, learning the art and science of thinking well is perhaps more important than ever.
