Now the greater the disproportion between private wishes and the general will, i.e., between manners and laws, the greater must be the power of repression. On the other side, the greatness of the state gives the depositaries of public authority greater temptations and additional means of abusing that authority, so that the more power is required by the government to control the people, the more power should there be in the sovereign to control the government.
From this twofold relation it follows that the continued proportion between the sovereign, the prince, and the people is not an arbitrary idea, but a consequence of the nature of the state. Moreover, it follows that one of the extremes, i.e., the nation, being constant, every time the double ratio increases or decreases, the simple ratio increases or diminishes in its turn; which cannot be unless the middle term is as often changed. From this we may conclude that there is no single absolute form of government, but there must be as many different forms of government as there are states of different size.
If the greater the numbers of the nation the less the ratio between its manners and its laws, by a fairly clear analogy, we may also say, the more numerous the magistrates, the weaker the government.
To make this principle clearer we will distinguish three essentially different wills in the person of each magistrate; first, his own will as an individual, which looks to his own advantage only; secondly, the common will of the magistrates, which is concerned only with the advantage of the prince, a will which may be called corporate, and one which is general in relation to the government and particular in relation to the state of which the government forms part; thirdly, the will of the people, or the sovereign will, which is general, as much in relation to the state viewed as the whole as in relation to the government viewed as a part of the whole. In a perfect legislature the private individual will should be almost nothing; the corporate will belonging to the government should be quite subordinate, and therefore the general and sovereign will is the master of all the others. On the other hand, in the natural order, these different wills become more and more active in proportion as they become centralised; the general will is always weak, the corporate will takes the second place, the individual will is preferred to all; so that every one is himself first, then a magistrate, and then a citizen; a series just the opposite of that required by the social order.
Having laid down this principle, let us assume that the government is in the hands of one man. In this case the individual and the corporate will are absolutely one, and therefore this will has reached the greatest possible degree of intensity. Now the use of power depends on the degree of this intensity, and as the absolute power of the government is always that of the people, and therefore invariable, it follows that the rule of one man is the most active form of government.
If, on the other hand, we unite the government with the supreme power, and make the prince the sovereign and the citizens so many magistrates, then the corporate will is completely lost in the general will, and will have no more activity than the general will, and it will leave the individual will in full vigour. Thus the government, though its absolute force is constant, will have the minimum of activity.
These rules are incontestable in themselves, and other considerations only serve to confirm them. For example, we see the magistrates as a body far more active than the citizens as a body, so that the individual will always counts for more. For each magistrate usually has charge of some particular duty of government; while each citizen, in himself, has no particular duty of sovereignty. Moreover, the greater the state the greater its real power, although its power does not increase because of the increase in territory; but the state remaining unchanged, the magistrates are multiplied in vain, the government acquires no further real strength, because it is the depositary of that of the state, which I have assumed to be constant. Thus, this plurality of magistrates decreases the activity of the government without increasing its power.
Having found that the power of the government is relaxed in proportion as the number of magistrates is multiplied, and that the more numerous the people, the more the controlling power must be increased, we shall infer that the ratio between the magistrates and the government should be inverse to that between subjects and sovereign, that is to say, that the greater the state, the smaller the government, and that in like manner the number of chiefs should be diminished because of the increased numbers of the people.
In order to make this diversity of forms clearer, and to assign them their different names, we shall observe in the first place that the sovereign may entrust the care of the government to the whole nation or to the greater part of the nation, so that there are more citizen magistrates than private citizens. This form of government is called Democracy.
Or the sovereign may restrict the government in the hands of a lesser number, so that there are more plain citizens than magistrates; and this form of government is called Aristocracy.
