" It has been said that the French revolution resulted from philosophy, and it is not without reason that philosophy has been called Weltweisheit [world wisdom]; for it is not only truth in and for itself, as the pure essence of things, but also truth in its living form as exhibited in the affairs of the world. We should not, therefore, contradict the assertion that the revolution received its first impulse from philosophy.

Never since the sun had stood in the firmament and the planets revolved around him had it been perceived that man's existence centres in his head, i.e. in thought, inspired by which he builds up the world of reality. Not until now had man advanced to the recognition of the principle that thought ought to govern spiritual reality. This was accordingly a glorious mental dawn. All thinking being shared in the jubilation of this epoch. Emotions of a lofty character stirred men's minds at that time; a spiritual enthusiasm thrilled through the world, as if the reconciliation between the divine and the secular was now first accomplished.
