"It is not enough to pay out of one's purse," says a moralist;[63] "one must also pay with one's person." Certainly, it is not for any one's pleasure that he leaves his parents and friends, his work and habits, to go to do military service in barracks, and, if needs be, to fight on the frontiers. But who will defend the country in case of attack if it be not its young and robust men? And must they not learn the use of arms in order to be efficient on the day when the country shall need them? This is why there are armies. Certainly, it would be a thousand times better if there were no need of this, if all nations were just enough never to make war with each other. But whilst this ideal is being realized, the least any one can do is to hold himself in readiness to defend his liberty, his honor.... Thanks to a good army, one not only can remain quiet at home, but the humblest citizen is respected wherever he goes, wherever his interests take him. In looking carefully at the matter it can be seen that even in respect to simple interests, the time spent in the service of the flag, is nothing in comparison with the advantages derived from it. Is it not because others have been there before us that we have been enabled to grow up peacefully and happy to the age of manhood? Is it not just that we should take their place and in our turn watch over the country? And when we return, others will take our place, and we, in our turn, shall be enabled to raise a family, attend to our business, and lead a quiet and contented life. Let us add to these judicious remarks that military service is a school of discipline, order, obedience, courage, patience, and as such, contributes to strengthening the mind and body, to developing personality, to forming good citizens. The principal infractions of the duty of military service are: 1, _mutilations_ by which some render themselves improper for service; 2, _simulated infirmities_ by which one tries to escape from the obligation; 3, _desertion_ in times of war, and what is more criminal still, _passing over to the enemy_; 4, _insubordination_ or disobedience to superiors.
