The point of this enterprise, as I see it, is to revitalize and elevate a constitutional debate that, in my estimation, has gotten bogged down. On the political Left, constitutional theory has to satisfy a vast range of “progressive” policy commitments before it can get a hearing. On the Right, a well-intentioned insistence on interpreting the Constitution one clause at a time has been taken to excess. In the process, it has crowded out a proper and urgent appreciation of the Constitution’s broader purposes—its “genius,” as John Marshall used to say.
