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.

Power, from the standpoint of experience, is merely the relation that exists between the expression of someone’s will and the execution of that will by others.

To explain the conditions of that relationship we must first establish a conception of the expression of will, referring it to man and not to the Deity.
