"If that's the case, though, why did the Union, under Lincoln, so catastrophically fail? The easy answer might be that no strategy anticipates all contingencies, that every solution creates new problems, and that these can, at times, overwhelm. The harsher one--although I think the more accurate one--lies in the possibility that the Founders left the Union to test itself: knowing the need to proportion aspirations to capabilities, recognizing the incompatibilities in good things, they chose to save their new state, and leave to their descendants the saving of its soul. Augustine and Machiavelli had both seen in proportionality a way to balance the respective claims of souls and states: their differences lay in whether equilibria reached required accountability to God. Augustine said yes and labored mightily to provide it. Machiavelli's God left statecraft to man. Americans, in varieties almost as infinite as those of Elizabeth I, straddled this divide: they could be, like their early leaders, coolly pragmatic, like their revivalists fiercely religious, and like their entrepreneurs anywhere in between. What's clear, though, is that few in the young republic questioned--at least not openly--what so many in the mature republic would give their lives to change: the anomaly that a Constitution promising a "more perfect Union" assumed slavery's legality. 69"
