Ralph Waldo Emerson
Towards all this external evil the man within the breast assumes a warlike attitude, and affirms his ability to cope single-handed with the infinite army of enemies. To this military attitude of the soul we give the name of Heroism. Its rudest form is the contempt for safety and ease, which makes the attractiveness of war. It is a self-trust which slights the restraints of prudence, in the plenitude of its energy and power to repair the harms it may suffer. The hero is a mind of such balance that no disturbances can shake his will, but pleasantly and as it were merrily he advances to his own music, alike in frightful alarms and in the tipsy mirth of universal dissoluteness. There is somewhat not philosophical in heroism; there is somewhat not holy in it; it seems not to know that other souls are of one texture with it; it hath pride; it is the extreme of individual nature. Nevertheless we must profoundly revere it. There is somewhat in great actions which does not allow us to go behind them. Heroism feels and never reasons, and therefore is always right; and although a different breeding, different religion and greater intellectual activity would have modified or even reversed the particular action, yet for the hero that thing he does is the highest deed, and is not open to the censure of philosophers or divines. It is the avowal of the unschooled man that he finds a quality in him that is negligent of expense, of health, of life, of danger, of hatred, of reproach, and that he knows that his will is higher and more excellent than all actual and all possible antagonists.
The characteristic of genuine heroism, is its persistency. All men have wandering impulses, fits and starts of generosity. But when you have resolved to be great, abide by yourself, and do not weakly try to reconcile yourself with the world. The heroic cannot be the common, nor the common the heroic. Yet we have the weakness to expect the sympathy of people in those actions whose excellence is that they outrun sympathy and appeal to a tardy justice. If you would serve your brother it is fit for you to serve him, do not take back your words when you find that prudent people do not commend you. Be true to your own act, and congratulate yourself if you have done something strange and extravagant and broken the monotony of a decorous age. It was a high counsel that I once heard given to a young person, “Always do what you are afraid to do”.
