Heroism works in contradiction to the voice of mankind and in contradiction, for a time, to the voice of the great and good. Heroism is an obedience to a secret impulse of an individual's character. Now to no other man can its wisdom appear as it does to him, for every man must be supposed to see a little farther on his own proper path than any one else. Therefore just and wise men take umbrage at his act, until after some little time be past: then they see it to be in unison with their acts. All prudent men see that the action is clean contrary to a sensual prosperity; for every heroic act measures itself by its contempt of some external good. But it finds its own success at last, and then the prudent also extol.
