Book excerpt: Saint Augustine's political thought has usually been interpreted by modern readers as suggesting that politics is based on sin. In Augustine and Politics as Longing in the World, John von Heyking shows that Augustine actually considered political life a substantive good that fulfills a human longing for a kind of wholeness. Rather than showing Augustine as supporting the Christian church's domination of politics, von Heyking argues that he held a subtler view of the relationship between religion and politics, one that preserves the independence of political life. And while many see his politics as based on a natural-law ethic or on one in which authority is conferred by direct revelation, von Heyking shows how Augustine held to an understanding of political ethics that emphasizes practical wisdom and judgment in a mode that resembles Aristotle rather than Machiavelli.
