In this unit students examine the four most influential Chinese philosophical traditions developed during the Zhou period (roughly 6th-3rd centuries B.C.E.). The four philosophies students study include: (1) Confucianism; (2) Mohism; (3) Daoism (Taoism); and (4) Legalism. In three lessons, students compare the ideas of these schools and explore how such ideas were conditioned by and, in turn, impacted society, economy, government, and culture. The unit uses a "dramatic moment" situated in the historic context and provides primary sources for students to examine during the course of the unit. The unit also contains "Teacher Background Materials" and "Lessons Plans with Student Resources." (EH)
