The Wealth of Nations

suitable to their respective stations, both themselves and the other officers of government and law, whom they are obliged to maintain. In the little agrarian states of ancient Greece, a fourth or a fifth part of the whole body of the people considered the themselves as soldiers, and would sometimes, it is said, take the field. Among the civilized nations of modern Europe, it is commonly computed, that not more than the one hundredth part of the inhabitants of any country can be employed as soldiers, without ruin to the country which pays the expense of their service. The expense of preparing the army for the field seems not to have become considerable in any nation, till long after that of maintaining it in the field had devolved entirely upon the sovereign or commonwealth. In all the different republics of ancient Greece, to learn his military exercises, was a necessary part of education imposed by the state upon every free citizen. In every city there seems to have been a public field, in which, under the protection of the public magistrate, the young people were taught their different exercises by different masters. In this very simple institution consisted the whole expense which any Grecian state seems ever to have been at, in preparing its citizens for war. In ancient Rome, the exercises of the Campus Martius answered the same purpose with those of the Gymnasium in ancient Greece. Under the feudal governments, the many public ordinances, that the citizens of every district should practise archery, as well as several other military exercises, were intended for promoting the same purpose, but do not seem to have promoted it so well. Either from want of interest in the officers entrusted with the execution of those ordinances, or from some other cause, they appear to have been universally neglected; and in the progress of all those governments, military exercises seem to have gone gradually into disuse among the great body of the people. In the republics of ancient Greece and Rome, during the whole period of their existence, and under the feudal governments, for a considerable time after their first establishment, the trade of a soldier was not a separate, distinct trade, which constituted the sole or principal occupation of a particular class of citizens; every subject of the state, whatever might be the ordinary trade or occupation by which he gained his livelihood, considered himself, upon all ordinary occasions, as fit likewise to exercise the trade of a soldier, and, upon many extraordinary occasions, as bound to exercise it. The art of war, however, as it is certainly the noblest of all arts, so, in the progress of improvement, it necessarily becomes one of the most complicated among them. The state of the mechanical, as well as some other arts, with which it is necessarily connected, determines the degree of perfection to which it is capable of being carried at any particular time. But in order to carry it to this degree of perfection, it is necessary that it should become the sole or principal occupation of a particular class of citizens; and the division of labour is as necessary for the improvement of this, as of every other art. Into other arts, the division of labour is naturally introduced by the prudence of individuals, who find that they promote their private interest better by confining themselves to a particular trade, than by exercising a great number. But it is the wisdom of the state only, which can render the trade of a soldier a particular trade, separate and distinct from all others. A private citizen, who, in time of profound peace, and without any particular encouragement from the public, should spend the greater part of his time in military exercises, might, no doubt, both improve himself very much in them, and amuse himself very well; but he certainly would not promote his own interest. It is the wisdom of the state only, which can render it for his interest to give up the greater part of his time to this peculiar occupation; and states have not always had this wisdom, even when their circumstances had become such, that the preservation of their existence required that they should have it. A shepherd has a great deal of leisure; a husbandman, in the rude state of husbandry, has some; an artificer or manufacturer has none at all. The first may, without any loss, employ a great deal of his time in martial exercises; the second may employ some part of it; but the last cannot employ a single hour in them without some loss, and his attention to his own interest naturally leads him to neglect them altogether. Those improvements in husbandry, too, which the progress of arts and manufactures necessarily introduces, leave the husbandman as little leisure as the artificer. Military exercises come to be as much neglected by the inhabitants of the country as by those of the town, and the great body of the people becomes altogether unwarlike. That wealth, at the same time, which always follows the improvements of agriculture and manufactures, and which, in reality, is no more than the accumulated produce of those improvements, provokes the invasion of all their neighbours. An industrious, and, upon that account, a wealthy nation, is of all nations the most likely to be attacked; and unless the state takes some new measure for the public defence, the natural habits of the people render them altogether incapable of defending themselves. In these circumstances, there seem to be but two methods by which the state can make any tolerable provision for the public defence. It may either, first, by means of a very rigorous police, and in spite of the whole bent of the interest, genius, and inclinations of the people, enforce the practice of military exercises, and oblige either all the citizens of the military age, or a certain number of them, to join in some measure the trade of a soldier to whatever other trade or profession they may happen to carry on. Or, secondly, by maintaining and employing a certain number of citizens in the constant practice of military exercises, it may render the trade of a soldier a particular trade, separate and distinct from all others. If the state has recourse to the first of those two expedients, its military force is said to consist in a militia; if to the second, it is said to consist in a standing army. The practice of military exercises is the sole or principal occupation of the soldiers of a standing army, and the maintenance or pay which the state affords them is the principal and ordinary fund of their subsistence. The practice of military exercises is only the occasional occupation of the soldiers of a militia, and they derive the principal and ordinary fund of their subsistence from some other occupation. In a militia, the character of the labourer, artificer, or tradesman, predominates over that of the soldier; in a standing army, that of the soldier predominates over every other character; and in this distinction seems to consist the essential difference between those two different species of military force. Militias have been of several different kinds. In some countries, the citizens destined for defending the state seem to have been exercised only, without being, if I may say so, regimented; that is, without being divided into separate and distinct bodies of troops, each of which performed its exercises under its own proper and permanent officers. In the republics of ancient Greece and Rome, each citizen, as long as he remained at home, seems to have practised his exercises, either separately and independently, or with such of his equals as he liked best; and not to have been attached to any particular body of troops, till he was actually called upon to take the field. In other countries, the militia has not only been exercised, but regimented. In England, in Switzerland, and, I believe, in every other country of modern Europe, where any imperfect military force of this kind has been established, every militiaman is, even in time of peace, attached to a particular body of troops, which performs its exercises under its own proper and permanent officers. Before the invention of fire-arms, that army was superior in which the soldiers had, each individually, the greatest skill and dexterity in the use of their arms. Strength and agility of body were of the highest consequence, and commonly determined the fate of battles. But this skill and dexterity in the use of their arms could be acquired only, in the same manner as fencing is at present, by practising, not in great bodies, but each man separately, in a particular school, under a particular master, or with his own particular equals and companions. Since the invention of fire-arms, strength and agility of body, or even extraordinary dexterity and skill in the use of arms, though they are far from being of no consequence, are, however, of less consequence. The nature of the weapon, though it by no means puts the awkward upon a level with the skilful, puts him more nearly so than he ever was before. All the dexterity and skill, it is supposed, which are necessary for using it, can be well enough acquired by practising in great bodies. Regularity, order, and prompt obedience to command, are qualities which, in modern armies, are of more importance towards determining the fate of battles, than the dexterity and skill of the soldiers in the use of their arms. But the noise of fire-arms, the smoke, and the invisible death to which every man feels himself every moment exposed, as soon as he comes within cannon-shot, and frequently a long time before the battle can be well said to be engaged, must render it very difficult to maintain any considerable degree of this regularity, order, and prompt obedience, even in the beginning of a modern battle. In an ancient battle, there was no noise but what arose from the human voice; there was no smoke, there was no invisible cause of wounds or death. Every man, till some mortal weapon actually did approach him, saw clearly that no such weapon was near him. In these circumstances, and among troops who had some confidence in their own skill and dexterity in the use of their arms, it must have been a good deal less difficult to preserve some degree of regularity and order, not only in the beginning, but through the whole progress of an ancient battle, and till one of the two armies was fairly defeated. But the habits of regularity, order, and prompt obedience to command, can be acquired only by troops which are exercised in great bodies. A militia, however, in whatever manner it may be either disciplined or exercised, must always be much inferior to a well disciplined and well exercised standing army. The soldiers who are exercised only once a week, or once a-month, can never be so expert in the use of their arms, as those who are exercised every day, or every other day; and though this circumstance may not be of so much consequence in modern, as it was in ancient times, yet the acknowledged superiority of the Prussian troops, owing, it is said, very much to their superior expertness in their exercise, may satisfy us that it is, even at this day, of very considerable consequence. The soldiers, who are bound to obey their officer only once a-week, or once a-month, and who are at all other times at liberty to manage their own affairs their own way, without being, in any respect, accountable to him, can never be under the same awe in his presence, can never have the same disposition to ready obedience, with those whose whole life and conduct are every day directed by him, and who every day even rise and go to bed, or at least retire to their quarters, according
