Physical courage may be educated; but it must be trained for its own sake. We say again, it must not be left to moral courage to include it, for the two faculties have different elements,--and what God has joined, human inconsistency may put asunder. The disjunction is easy to explain. Many men, when committed on the right side of any question, get credit for a "moral courage," which is, in their case, only an intense egotism, isolating them from all demand for human sympathy. In the best cause, they prefer to belong to a party conveniently small, and, on the slightest indications of popular approbation, begin to suspect themselves of compromise. The abstract martyrdom of unpopularity is therefore clear gain to them; but when it comes to the rack and the thumbscrew, the revolver and the bowie-knife, the same habitual egotism makes them cowards. These men are annoying in themselves, and still worse because they throw discredit on the noble and unselfish reformers with whom they are identified in position. But even among this higher class there are differences of temperament, and it costs one man an effort to face the brute argument of the slung-shot, while another's fortitude is not seriously tested till it comes to facing the newspaper editors. We have given but a few aspects of a rich and endless theme, and have depicted these more by examples than analysis, mindful of the saying of Sidney, that Alexander received more bravery of mind by the example of Achilles than by hearing the definition of fortitude. If we have seemed to draw illustrations too profusely from the records of battles, it is to be remembered, that, even if war be not the best nurse of heroisms, it is their best historian. The chase, for instance, though perhaps as prolific in deeds of daring as the camp, has found few Cummings and Gerards for annalists, and the more trivial aim of the pursuit diminishes the permanence of its records. The sublime fortitude of hospitals, the bravery shown in infected cities, the fearlessness of firemen and of sailors, these belong to those times of peace which have as yet few historians. But we have sought to exhibit the deep foundations and instincts of courage, and it matters little whence the illustrations come. Doubtless, for every great deed ever narrated, there were a hundred greater ones untold; and the noblest valor of the world may sleep unrecorded, like the heroes before Homer.
