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.
