Leo Strauss's writings reveal a subtle but consistent set of accusations against the influence of Christian thinkers on political philosophy. These accusations may be summarized in three charges. First, the attempt by Aquinas and other Christian scholastics to synthesize faith and reason led later philosophers to eschew prudence in favor of a humane project to employ science to transform political life. The result was the destruction of the modus vivendi, safeguarded by classical political philosophy, between pious citizens and diffident but inwardly free philosophers. Second, the rationalization of political life implies that a universal regime is possible. But, unless all men become philosophers, this universal regime can be only a universal tyranny, ruled by means of perverted faith in the guise of a final philosophy. Third, Christian thinkers must bear ultimate responsibility for precipitating the early modern rejection of classical political philosophy. Without the Christian appropriation of Aristotle, there might never have been a Machiavelli or a Hobbes.
