And while this is true of individual men, it holds good also of a concourse of men living together in one republic, who will arrive at that measure of perfection which the institutions of their State permit. And although I have already said on another occasion that a good militia is the foundation of all States, and where that is wanting there can neither be good laws, nor aught else that is good, it seems to me not superfluous to say the same again; because in reading this history of Titus Livius the necessity of such a foundation is made apparent in every page. It is likewise shown that no army can be good unless it be thoroughly trained and exercised, and that this can only be the case with an army raised from your own subjects. For as a State is not and cannot always be at war, you must have opportunity to train your army in times of peace; but this, having regard to the cost, you can only have in respect of your own subjects.
When Camillus, as already related, went forth to meet the Etruscans, his soldiers on seeing the great army of their enemy, were filled with fear, thinking themselves too to withstand its onset. This untoward disposition being reported to Camillus, he showed himself to his men and by visiting their tents, and conversing with this and the other among them, was able to remove their misgivings; and, finally, without other word of command, he bade them “each do his part as he had learned and been accustomed.” Now, any one who well considers the methods followed by Camillus, and the words spoken by him to encourage his soldiers to face their enemy, will perceive that these words and methods could never have been used with an army which had not been trained and disciplined in time of peace as well as of war. For no captain can trust to untrained soldiers or look for good service at their hands; nay, though he were another Hannibal, with such troops his defeat were certain. For, as a captain cannot be present everywhere while a battle is being fought, unless he have taken all measures beforehand to render his men of the same temper as himself, and have made sure that they perfectly understand his orders and arrangements, he will inevitably be destroyed.
