Morgenthau, Hans. “A Realist theory of International Relations” in Politics among Nations: The Struggle for Power and Peace. New York: McGraw-Hill Education, 2005. This chapter sets forth the six fundamental principles of political realism. For a criterion of effectiveness, the article argues that a theory must be evaluated by its purpose, in this case, “[bringing] order and meaning to a mass of phenomena that without it would remain disconnected and unintelligible” (3). Focusing on the real and observable phenomena of international relations, political realism critiques the utopian thought of its idealist counterparts, who believe in the “essential goodness and infinite malleability of human nature” and who “[blame] the failure of the social order to measure up to the rational standards on lack of knowledge and understanding, obsolescent social institutions, or the depravity of certain isolated individuals or groups” (3). In contrast, the first principle of political realism maintains that politics are grounded in observable laws of human nature – any idealistic attempt to challenge these laws will only lead to failure.
