In this lesson, students will explore the vice of hubris or pride in a constitutional republic in this lesson on civic virtue. Students will examine the life of the heroic, but flawed, career of General Douglas MacArthur in World War II and the Korean War. Through a historical narrative, discussion guide, primary sources, and other activities, students will analyze whether MacArthur exhibited the vice of hubris and what effect it might have had on civil-military relations in a constitutional republic.
