The Daily Stoic

General Jim Mattis has spent his life proving that philosophy is not just for the classroom. In today’s episode, Margaret Hoover interviews General Mattis, former U.S. Secretary of Defense, and Ryan about why philosophy matters most when things are difficult. They discuss how leaders fall back on their first principles in a crisis, and what Marcus Aurelius, George Washington, and Abraham Lincoln can still teach us about courage, citizenship, and character today.
