Question

Which of the following books have been written by Hans. J. Morganthau ? 
(A) The Purpose of American Politics 
(B) Truth and Power 
(C) In Defense of the National Interest

Accepted Answer

The correct option is 4:

The correct option is 4, which includes (A), (B), and (C), meaning all three books—*The Purpose of American Politics*, *Truth and Power*, and *In Defense of the National Interest*—were authored by the renowned political theorist Hans J. Morgenthau. Morgenthau is considered one of the founding fathers of the realist school of international relations, and his writings heavily influenced American foreign policy debates during the Cold War era and beyond. While his magnum opus is undoubtedly *Politics Among Nations*, these three works represent critical aspects of his thought, covering American foreign policy, the ethical dilemmas of statecraft, and the concept of national interest. *The Purpose of American Politics*, published in 1960, focused on defining the core ethical purpose of American political life, arguing that it must transcend mere power politics to achieve freedom and justice, both at home and abroad. *In Defense of the National Interest*, published earlier, in 1951, was a powerful, realist argument concerning how American foreign policy should be structured around the concept of national interest, defined in terms of power, a core tenet of his political realism. Lastly, *Truth and Power: Essays of a Decade, 1960-1970*, is a collection of essays and commentaries that critically examine U.S. foreign policy, particularly during the Vietnam War, exploring the tension between ethical truth and political power. His authorship of all three books confirms that Option 4 is the most comprehensive and correct choice.

The incorrect option is 1:

Option 1, "(A) and (B)," is incorrect because it excludes book (C), *In Defense of the National Interest*. This book is a landmark work in Morgenthau's bibliography, where he developed the core idea of political realism—that states primarily act based on their national interest, defined as power. Ignoring this work significantly misrepresents the scope of his critical publications, which frequently addressed the practical application of realist principles in American diplomacy. A thorough study of Morgenthau’s influence on foreign policy requires acknowledging this work alongside his other critical analyses.

The incorrect option is 2:

Option 2, "(A) and (C)," is incorrect because it omits book (B), *Truth and Power*. While *The Purpose of American Politics* and *In Defense of the National Interest* are certainly his works and major contributions, the collection *Truth and Power* (1970) showcases Morgenthau’s intellectual evolution and his powerful critiques of the political establishment concerning the Vietnam conflict. By omitting this work, Option 2 fails to account for Morgenthau’s crucial role as a public intellectual who applied his realist theories to contemporary political issues, particularly his later writings on ethics in statecraft.

The incorrect option is 3:

Option 3, "(B) and (C)," is incorrect because it excludes book (A), *The Purpose of American Politics*. This exclusion is significant as the book represents one of Morgenthau's key attempts to define the moral and philosophical underpinnings of the American experiment, moving beyond his purely realist international theory to address domestic political goals. It is an important transitional text in his career, bridging his famous theories of international politics with an analysis of American democratic ideals. Since he authored all three listed works, any option that fails to include all of them is factually incomplete and incorrect.
