Morally the wielder of power appears to cause the event; physically it is those who submit to the power. But as the moral activity is inconceivable without the physical, the cause of the event is neither in the one nor in the other but in the union of the two.
Or in other words, the conception of a cause is inapplicable to the phenomena we are examining.
In the last analysis we reach the circle of infinity—that final limit to which in every domain of thought man’s reason arrives if it is not playing with the subject. Electricity produces heat, heat produces electricity. Atoms attract each other and atoms repel one another.
Speaking of the interaction of heat and electricity and of atoms, we cannot say why this occurs, and we say that it is so because it is inconceivable otherwise, because it must be so and that it is a law. The same applies to historical events. Why war and revolution occur we do not know. We only know that to produce the one or the other action, people combine in a certain formation in which they all take part, and we say that this is so because it is unthinkable otherwise, or in other words that it is a law.

If history dealt only with external phenomena, the establishment of this simple and obvious law would suffice and we should have finished our argument. But the law of history relates to man. A particle of matter cannot tell us that it does not feel the law of attraction or repulsion and that that law is untrue, but man, who is the subject of history, says plainly: I am free and am therefore not subject to the law.
