We must now accompany Mr. Mill on the next stage of his argument. Does any combination of the three simple forms of government afford the requisite securities against the abuse of power? Mr. Mill complains that those who maintain the affirmative generally beg the question; and proceeds to settle the point by proving, after his fashion, that no combination of the three simple forms, or of any two of them, can possibly exist. From the principles which we have already laid down it follows that, of the objects of human desire, and, speaking more definitely, of the means to the ends of human desire, namely, wealth and power, each party will endeavour to obtain as much as possible.

“If any expedient presents itself to any of the supposed parties effectual to this end, and not opposed to any preferred object of pursuit, we may infer with certainty that it will be adopted. One effectual expedient is not more effectual than obvious. Any two of the parties, by combining, may swallow up the third. That such combination will take place appears to be as certain as any thing which depends upon human will; because there are strong motives in favour of it, and none that can be conceived in opposition to it.... The mixture of three of the kinds of government, it is thus evident, cannot possibly exist.... It may be proper to inquire whether an union may not be possible of two of them....

“Let us first suppose, that monarchy is united with aristocracy. Their power is equal or not equal. If it is not equal, it follows, as a necessary consequence, from the principles which we have already established, that the stronger will take from the weaker till it engrosses the whole. The only question therefore is, What will happen when the power is equal?

“In the first place, it seems impossible that such equality should ever exist. How is it to be established? or, by what criterion is it to be ascertained? If there is no such criterion, it must, in all eases, be the result of chance. If so, the chances against it are as infinity to one. The idea, therefore, is wholly chimerical and absurd....

“In this doctrine of the mixture of the simple forms of government is included the celebrated theory of the balance among the component parts of a government. By this it is supposed that, when a government is composed of monarchy, aristocracy, and democracy, they balance one another, and by mutual checks produce good government. A few words will suffice to show that, if any theory deserves the epithets of ‘wild, visionary and chimerical,’ it is that of the balance. If there are three powers, how is it possible to prevent two of them from combining to swallow up the third?

“The analysis which we have already performed will enable us to trace rapidly the concatenation of causes and effects in this imagined case. "We have already seen that the interest of the community, considered in the aggregate or in the democratical point of view, is, that each individual should receive protection; and that the powers which are constituted for that purpose should be employed exclusively for that purpose.... We have also seen that the interest of the king and of the governing aristocracy is directly the reverse. It is to have unlimited power over the rest of the community, and to use it for their own advantage. In the supposed case of the balance of the monarchical, aristocratical, and democratical powers, it cannot be for the interest of either the monarchy or the aristocracy to combine with the democracy; because it is the interest of the democracy, or community at large, that neither the king nor the aristocracy should have one particle of power, or one particle of the wealth of the community, for their own advantage.

“The democracy or community have all possible motives to endeavour to prevent the monarchy and aristocracy from exercising power, or obtaining the wealth of the community for their own advantage. The monarchy and aristocracy have all possible motives for endeavouring to obtain unlimited power over the persons and property of the community. The consequence is inevitable: they have all possible, motives for combining to obtain that power.”

If any part of this passage be more eminently absurd than another, it is, we think, the argument by which Mr. Mill proves that there cannot be an union of monarchy and aristocracy. Their power, he says, must be equal or not equal. But of equality there is no criterion. Therefore the chances against its existence are as infinity to one. If the power be not equal, then it follows, from the principles of human nature, that the stronger will take from the weaker, till it has engrossed the whole.

Now, if there be no criterion of equality between two portions of power there can be no common measure of portions of power. Therefore it is utterly impossible to compare them together. But where two portions of lower are of the same kind, there is no difficulty in ascertaining, sufficiently for all practical purposes, whether they are equal or unequal. It is easy to judge whether two men run equally fast, or can lift equal weights. Two arbitrators, whose joint decision is to be final, and neither of whom can do any thing without the assent of the other, possess equal power. Two electors, each of whom has a vote for a borough, possess, in that respect, equal power. If not, all Mr. Mill’s political theories fall to the ground at once. For, if it be impossible to ascertain whether two portions of power are equal, he never can show that, even under a system of universal suffrage, a minority might not carry every thing their own way, against the wishes and interests of the majority.

Where there are two portions of power differing in kind, there is, we admit, no criterion of equality. But then, in such a case, it is absurd to talk, as Mr. Mill does, about the stronger and the weaker. Popularly, indeed, and with reference to some particular objects, these words may very fairly be used. But to use them mathematically is altogether improper. If we are speaking of a boxing-match, we may say that some famous bruiser has greater bodily power than any man in England. If we are speaking of a pantomime, we may say the same of some very agile harlequin. But it would be talking nonsense to say, in general, that the power of Harlequin either exceeded that of the pugilist, or fell short of it.
