The problem of Enlightenment is not merely discovery of the truth but the conflict between the truth and the beliefs of men, which are incorporated into the law. Enlightenment begins from the tension between what men are compelled to believe by city and religion, on the one hand, and the quest for scientific truth on the other. … The innovation of the Enlightenment was the attempt to reduce that tension and to alter the philosopher’s relation to civil society. … The earlier thinkers accepted the tension and lived accordingly. Their knowledge was essentially for themselves, and they had a private life very different from their public life. They were themselves concerned with getting from the darkness to the light. Enlightenment was a daring attempt to shine that light on all men, partly for the sake of all men, partly for the sake of the progress of science. … Enlightenment was not only, or perhaps not even primarily, a scientific project but a political one. It began from the premise that the rulers could be educated, a premise not held by the Enlightenment’s ancient brethren.
