MARATHON: GOING THE DISTANCE
26 miles, 385 yards, an Athenian soldier named Pheidippides started it all when he covered the distance between the battlefield at Marathon and the marketplace at Athens. He raised his arms,shouted, "We conquer!" and promptly died. The rest is history and more than a little mythology. Since Pheidippides, the marathon has moved many miles from the realm of myth and metaphor into the strange territory of science and high tech. With a tip of the hat in the direction of this month's 118th running of the Boston Marathon -- and in recognition of his 15th season as host of IDEAS -- Paul Kennedy pays tribute to the ultimate test of physical endurance.

THE HUMAN FACTOR - HANNAH ARENDT
Was Adolph Eichmann not ultimately responsible for the destruction of six million Jews? Or were Jews themselves partially to blame for their own fate? Fifty years ago, the political philosopher Hannah Arendt published a famous book that seemed to imply these things, and created an instant uproar that has never ended. Roger Berkowitz, Adam Gopnik, Rivka Galchen and Adam Kirsch debate the reality behind Hannah Arendt and her ideas.

TINCTOR'S FOUL MANUAL
Our ideas about witches and witch hunts may come from an extraordinary manuscript found in the University of Alberta Library. It's one of only four known copies. Written in the 1400s and now being re-translated from medieval French, it created the framework for witch hunts. Dave Redel carefully opens its cover.

STALKING THE HOLY REVISITED

As the canonization of Pope John Paul II approaches, IDEAS looks again at how saints are "made". Contributor Michael Higgins entwines threads from anthropology, politics, theology, and psychology -- as well as case-studies of saints like Mother Teresa, Pope Pius XII, and Padre Pio. The result is an extensive examination of sainthood, which brings surprising answers to one man's search for the holy.

WALKING MATTERS, Part 2
Ever since our ancestors rose to their feet, our species has been defined by walking upright. But the act involves our minds as well as our bodies. We interpret the act of walking, and give it our stamp - from ramblers to Rousseau, from models and tramps to Buddhist monks. In this two-part series, Marilyn Powell explores the world of walking and what it means to us.
