In this lecture, I define a republic in two ways. First as a mixed government: monarchy, aristocracy, and democracy, comparing it to the human person (mind, soul, stomach). Thus, the republic is always flawed and always in a life cycle of birth, middle age, and death. Second by its elements: virtue, property (as the right to moral ownership), a well-armed citizenry, and decentralized decision making. I also focus on Articles 1-3, 6 of the Northwest Ordinance, and I talk about Hillsdale’s connection (with historian Ransom Dunn’s creation of the Republican Party in 1854—inspired by Article Six of the Northwest Ordinance) to all of this.
