Political philosophy as we know it blossomed with the arrival of European immigrants like Hannah Arendt, Leo Strauss, and Eric Vogelin after World War II. These refugee scholars challenged their American colleagues in at least three important ways. They dared political scientists to be more morally conscientious, to focus on matters of real importance, and to develop a more refined historical sensibility.

These authors suggested that the fact/value distinction at the center of the social scientific enterprise was indicative of a moral decay at the center of Western civilization. This decay paved the way for Nazism in the twenties and thirties, and possibly would contribute to Soviet victory in the Cold War if changes were not made. Less Cassandra-like was their charge that political scientists were primarily interested in refining the study of the insignificant. What they could measure through their dominant methods—public opinion, voting patterns, etc.—was trivial in comparison to the classical analysis of regime types, or the nature of man, or the purpose of the common life.

As a result, these philosophers offered history, unabashedly Western history, as a resource for studying these timeless questions of political inquiry. To their minds, questioning the nature of tyranny, or the status of authority, was still worthwhile; fundamental, in fact. They encouraged other political scientists to incorporate these themes into their practice. Indeed, Steven Smith's contribution to this colloquy represents a renewed effort in this vein.
