The second semester of Social Foundations spans a thousand years, from the rise of Islam and the reunification of China under the Tang dynasty (in the 7th century C.E.) through the Scientific Revolution and the decline of the Mogul empire in India. This course invites students to consider great ideas that have often helped earlier peoples organize their lives--but which have also set them in conflict, sometimes with other communities, sometimes among themselves. Such ideas have sparked movements for ethical and social reform, for conquest, for the recovery of lost classics, and for religious renewal.
