(p. 199) This is politics seen through the eyes of an Enlightened rationalist. The American experiment was, literally, an experiment, like one of Priestley’s elaborate concoctions in the Fair Hill lab: a system of causes and effects, checks and balances, that could only be truly tested by running the experiment with live subjects. The political order was to be celebrated not because it had the force of law, or divine right, or a standing army behind it. Its strength came from its internal balance, or homeostasis, its ability to rein in and subdue efforts to destabilize it.
