Students of American political theory find themselves in general agreement concerning the character and significance of their most celebrated document, The Federalist. Few deny that this series of essays in support of the Constitution by Alexander Hamilton, James Madison, and John Jay represents a substantial contribution to the literature of political theory. The nature of the contribution is also well established. The Federalist, it is agreed, is a skillful exposition of the principles of constitutional republicanism — an exposition not haphazard or fanciful, but controlled by constant reference to the capacities and limitations of the political animal. The latter point is often emphasized; Benjamin F. Wright states: “The aspect of The Federalist which is of universal applicability is … its recognition of the importance of human nature in politics, togetherwith its remarkably penetrating analysis of the motives and the behavior of men in a free society.” x Finally, there is agreement on the general outlines of this theory of human nature. The authors of The Federalist, it is said, were decidedly “realistic,” brooking no illusions of the inherent goodness or rationality of man, but holding firm to “a conception of human corruptibility.” 2 The adjective most often employed is “pessimistic.”
