This is a fact we often miss about our Constitution. It works by setting competing interests and powers against each other, which critics sometimes caricature as substituting an almost mechanical proceduralism for morally substantive civic formation. But that is precisely wrong. This approach actually begins from the insight that, in order to be properly formative, our politics must always be in motion—that moral formation is a matter of establishing habits, and that civic habits are built up by civic action more than by a proper arrangement of rules. The different interests, priorities, and power centers set against each other in our system do not rest against each other, like interlocking beams holding up a roof. Rather, they push, pull, and tug at each other and unceasingly compete for position. They are living political actors, not inanimate structural supports. And none can achieve anything without dealing with the others, who are always in their way. The result is a peculiar style of politics, which feels frustrating and acrimonious at almost any given instant, but can be remarkably dynamic in the long run.
A brilliant essay.
