Napoleon, the greatest of the conquerors, is a sufficient proof that great men of action are criminals, and therefore, not geniuses. One can understand him by thinking of the tremendous intensity with which he tried to escape from himself. There is this element in all the conquerors, great or small. Just because he had great gifts, greater than those of any emperor before him, he had greater difficulty in stifling the disapproving voice within him. The motive of his ambition was the craving to stifle his better self.
