In courage itself, too, there are many varieties. The courage of the soldier and the courage of the martyr are not the same, and it by no means follows that either would possess that of the other. Not a few men who are capable of leading a forlorn hope, and who never shrink from the bayonet and the cannon, have shown themselves incapable of bearing the burden of responsibility, enduring long-continued suspense, taking decisions which might expose them to censure or unpopularity. The active courage that encounters and delights in danger is often found in men who show no courage in bearing suffering, misfortune, or disease. In passive courage the woman often excels the man as much as in active courage the man exceeds the woman. Even in active courage familiarity does much; sympathy and enthusiasm play great and often very various parts, and curious anomalies may be found. The Teutonic and the Latin races are probably equally distinguished for their military courage, but there is a clear difference between them in the nature of that courage and in the circumstances or conditions under which it is usually most splendidly displayed. The danger incurred by the gladiator was far greater than that which was encountered by the soldier, but Tacitus[62] mentions that when some of the bravest gladiators were employed in the Roman army they were found wholly inefficient, as they were much less capable than the ordinary soldiers of military courage. The circumstances of life are the great school for forming and strengthening the will, and in the excessive competition and struggle of modern industrialism this school is not wanting. But in ethical and educational systems the value of its cultivation is often insufficiently felt. Yet nothing which is learned in youth is so really valuable as the power and the habit of self-restraint, of self-sacrifice, of energetic, continuous and concentrated effort. In the best of us evil tendencies are always strong and the path of duty is often distasteful. With the most favourable wind and tide the bark will never arrive at the harbour if it has ceased to obey the rudder. A weak nature which is naturally kindly, affectionate and pure, which floats through life under the impulse of the feelings, with no real power of self-restraint, is indeed not without its charm, and in a well-organised society, with good surroundings and few temptations, it may attain a high degree of beauty; but its besetting failings will steadily grow; without fortitude, perseverance and principle, it has no recuperative energy, and it will often end in a moral catastrophe which natures in other respects much less happily compounded would easily avoid. Nothing can permanently secure our moral being in the absence of a restraining will basing itself upon a strong sense of the difference between right and wrong, upon the firm groundwork of principle and honour.
