This course surveys the historical development of Western moral philosophy, and then analyzes the role of morality in the conduct of foreign policy. It examines the use of ethical reasoning in helping to achieve the twin American goals of a moral foreign policy and protection of the national interest. What is unique about this course is that it conducts this examination in light of the Western, principally Judeo-Christian tradition that has historically, but decreasingly, guided American statecraft. The course contrasts this tradition with new philosophical concepts in America and explores the real and potential consequences of those concepts.
