(I rarely agree with Brooks, but I think he's on to something here, as much as I may disagree with his conclusion - gd)
When I was in college I took a course in the Enlightenment. In those days, when people spoke of the Enlightenment, they usually meant the French Enlightenment — thinkers like Descartes, Rousseau, Voltaire and Condorcet.
These were philosophers who confronted a world of superstition and feudalism and sought to expose it to the clarifying light of reason. Inspired by the scientific revolution, they had great faith in the power of individual reason to detect error and logically arrive at universal truth.
Their great model was Descartes. He aimed to begin human understanding anew. He’d discard the accumulated prejudices of the past and build from the ground up, erecting one logical certainty upon another.
What Descartes was doing for knowledge, others would do for politics: sweep away the old precedents and write new constitutions based on reason. This was the aim of the French Revolution.
