This class introduces the fundamentals of Buddhist thought, focusing on the foundational doctrinal, philosophical, and ethical ideas that have animated the Buddhist tradition from its earliest days in India 2500 years ago down to the present, in places such as Tibet, China, and Japan. Though there will be occasional discussion of the social and practical contexts of the Buddhist religion, the primary focus of this course lies on how traditional Buddhist thinkers conceptualize the universe, think about the nature of human beings, and propose that people should live their lives. Our main objects of inquiry are therefore the foundational Buddhist ideas, and the classic texts in which those ideas are put forth and defended, that are broadly speaking shared by all traditions of Buddhism. In the later part of the course, we take up some of these issues in the context of specific, regional forms of Buddhism, and watch some films that provide glimpses of Buddhist religious life on the ground.
