There is, and can be, no cause of an historical event except the one cause of all causes. But there are laws directing events, and some of these laws are known to us while we are conscious of others we cannot comprehend. The discovery of these laws is only possible when we have quite abandoned the attempt to find the cause in the will of some one man, just as the discovery of the laws of the motion of the planets was possible only when men abandoned the conception of the fixity of the earth.
