Rousseau (Volume 1 and 2‪)‬

Christianity is the name for a great variety of changes which took place during the first centuries of our era, in men's ways of thinking and feeling about their spiritual relations to unseen powers, about their moral relations to one another, about the basis and type of social union. So the Revolution is now the accepted name for a set of changes which began faintly to take a definite practical shape first in America, and then in France, towards the end of the eighteenth century; they had been directly prepared by a small number of energetic thinkers, whose speculations represented, as always, the prolongation of some old lines of thought in obedience to the impulse of new social and intellectual conditions.
