Robert R. Reilly is the author of the recently published book America on Trial: A Defense of the Founding. He examines the intellectual underpinnings of the ideas which inspired the creation a new nation in the New World. It’s a crackling read which is very relevant to today’s debates about racial justice. Reilly explains how America has drifted from its moorings in natural law.
This is a controversial interpretation of the founding documents -- the Declaration of Independence, the Constitution, the Federalist Papers and a few others. Philosophically, it projects an Aristotelian understanding of society and metaphysics onto the ideas of these founding fathers -- who were largely Protestant or Deists. But he makes a good case for it. He is arguing against both radicals who believe that the USA was based on slavery and therefore corrupt from its conception and against (mostly) Catholic theorists who believe that the Constitution embodies Enlightenment ideas which inevitably led to moral relativism.
