Alternatively, A Response to Steven Pinker.
There has never been as society that was more civilized in the humanist sense than the French society of the Enlightenment, nor one more completely convinced of the powers of reason and science to solve all the problems of life and to create a completely rational culture, based on a firm foundation of science and philosophy. Yet when this society, as represented by Condorcet and his friends, had the opportunity to put their ideas into practice in the first years of the French Revolution, they failed disastrously and were themselves destroyed, almost to a man, by the eruption of the irrational forces that they had released. One of the writers of the emigration has described in a remarkable passage how he came to realize the fallacies of the rationalist ideology in a sudden flash of intuition one night as he was making the terrible march across the frozen Zuyder Zee with the defeated English army in 1796, and how all the illusions of the Enlightenment dropped away from him under the cold light of the winter stars
