“We know that psychology is tremendously important in war. It is a field unlimited in extent, to which every conscientious soldier should give much time and study. Yet it cannot be learned as one learns mathematics. It must be sensed. Unfortunately we cannot formulate a set of psychological rules; human reactions can never be reduced to an exact science. War is governed by the uncertain and the unknown and the least known factor of all is the human element.”

“Psychology, as I understand it, means knowledge of the soul. Yet, how shall we speak about the souls of others, when we do not even know our own? Is there a single one of us who can say with certainty how he will react to a given event? Nevertheless, as leaders we must have some knowledge of the souls of our soldiers; because the soldier, the living man, is the instrument with which we have to work in war. The great commanders of all times had a real knowledge of the souls of their soldiers. Let us use a more simple phrase and call this knowledge of the soul, “knowledge of men.” Knowledge of men in all wars has proved an important factor to the leader. It is probable that this will be still more true in future wars.”
