Examining only those expressions of the will of historical persons which, as commands, were related to events, historians have assumed that the events depended on those commands. But examining the events themselves and the connection in which the historical persons stood to the people, we have found that they and their orders were dependent on events. The movement of nations is caused not by power, nor by intellectual activity, nor even by a combination of the two as historians have supposed, but by the activity of all the people who participate in the events, and who always combine in such a way that those taking the largest direct share in the event take on themselves the least responsibility and vice versa. 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.
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.
