Not to speak of the fact that no description of the collective activity of men can do without the conception of power, the existence of power is proved both by history and by observing contemporary events.
Whenever an event occurs a man appears or men appear, by whose will the event seems to have taken place. Napoleon III issues a decree and the French go to Mexico. The King of Prussia and Bismarck issue decrees and an army enters Bohemia. Napoleon I issues a decree and an army enters Russia. Alexander I gives a command and the French submit to the Bourbons. Experience shows us that whatever event occurs it is always related to the will of one or of several men who have decreed it.
The historians, in accord with the old habit of acknowledging divine intervention in human affairs, want to see the cause of events in the expression of the will of someone endowed with power, but that supposition is not confirmed either by reason or by experience.
On the one side reflection shows that the expression of a man’s will—his words—are only part of the general activity expressed in an event, as for instance in a war or a revolution, and so without assuming an incomprehensible, supernatural force—a miracle—one cannot admit that words can be the immediate cause of the movements of millions of men. On the other hand, even if we admitted that words could be the cause of events, history shows that the expression of the will of historical personages does not in most cases produce any effect, that is to say, their commands are often not executed, and sometimes the very opposite of what they order occurs.
Without admitting divine intervention in the affairs of humanity we cannot regard “power” as the cause of events.
