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.
