"The other old democracy... the one I teach about... was in Athens. Now Aristotle said democracy means "to rule and to be ruled in turns"... because the system the Athenians set up was designed to ensure that nobody would... cease power. So they took people and... forced them to be political units composed of multiple clans... so different clans had to be together. They couldn't be segregated, and they had a 10 month calendar and every month a different group was in charge. Hence to rule and to be ruled in turns. ...[I]t worked for 200 years. [Much of] our Constitution is based... on the experience of Ancient Athens, of . All of the Founders of this country... were well steeped in the history of the ancient world."
