National Humanities Medal Award Winner, Author, Revolutionary, Historian Professor Teofilo Ruiz explains how the witch persecutions began, what they consisted of, why they stopped, and what it means for humanity. A fascinating, broad and deep discussion with a brilliant and distinguished historical researcher and multi-award-winning teacher and author. From Professor Ruiz: “I think that the role of a historian, the role of a teacher—and I truly believe this—is to go against the grain. To argue. To be a contrarian. To make people think critically about things."
