2. If a watch be necessary to a railway guard, and he is bound to have one accordingly, it is also necessary, and he is bound to procure it, that the watch shall go and keep time. A watch that will not keep time is an unlawful article for him to depend upon, being tantamount to no watch, whereas he is bound to have a watch. Otherwise, be his watch large or small, gold, silver, or pinchbeck, all this is indifferent, so long as it be a reliable timekeeper. In like manner, we must have a State, we must have a government, and we must have a government that can govern. Monarchy, aristocracy, parliaments, wide or narrow franchise, centralisation, decentralisation, any one of these and countless other forms—apart from the means whereby it is set up—is a lawful government, where it is a workable one; unlawful, and forbidden by God and nature, where it cannot work. A form of government that from its own intrinsic defects could nowhere work, would be everywhere and always unlawful.
3. You cannot argue from the accomplished fact the lawfulness of the means whereby it was accomplished. Nor do we say that every form of government, which succeeds in governing, was originally set up in justice; nor again that the success of its rule is necessarily due to the use of just means. The Committee of Public Safety in Paris in 1794 did manage to govern, but it was erected in blood, and it governed by an unscrupulous disregard of everybody's rights. All that we say is, that no distribution of civil power as a distribution, or no polity as a polity (s. iii., n. 5, p. 312), is unlawful, if by it the government can be carried on. And the reason is plain. For all that nature requires is that there should be an efficient civil authority, not that this man should have it, or that one man or other should have it all, or that a certain class in council assembled should engross it, or that all the inhabitants of the country should participate in it. Any one of these arrangements that will work, satisfies the exigency of nature for civil rule, and is therefore in itself a lawful polity.
4. Working, and therefore, as explained, lawful polities are as multitudinous as the species of animals. Besides those that actually are, there is a variety without end, as of animals, so of polities, that might be and are not. We can classify only the main types. We ground our classification upon Ar., Pol., III., vii., modernising it so as to take in forms of representative government, whereof Aristotle had no conception.
(1) Monarchy, or the rule of the Single Person, in whose hands the whole power of the State is concentrated, e.g., Constantine the Great.
(2) Aristocracy, or the rule of the Few, which will be either direct or representative, according as either they themselves by their own votes at first hand, or representatives whom they elect, make the laws.
(3) Democracy, or the rule of the Many, that is, of the whole community. Democracy, again, is either direct (commonly called pure) or representative. The most famous approach in history to pure democracy is the government of Athens, B.C. 438-338.
(4) Limited Monarchy.
(a) Monarchy with Aristocracy, the government of England from 1688 to 1830.
(b) Monarchy with Democracy.
5. All civil government is for the governed, that is, for the community at large. The perversion of a polity is the losing sight of this principle, and the conducting of the polity in the interest of the governing body alone. By such perversion monarchy passes into tyranny, aristocracy into oligarchy, and democracy into ochlocracy or mob-rule. It might appear strange that, where the power rests with the whole people collectively, government should ever be carried on otherwise than in the interest of the entire community, did we not remember that the majority, with whom the power rests in a democracy, may employ it to trample on and crush the minority. Thus the Many may worry and harass the Few, the mean and poor the wealthy and noble: though commonly perhaps the worrying has been the other way about. Anyhow it is important to observe that there is no polity which of itself, and apart from the spirit in which it is worked, is an adequate safeguard and rock of defence against oppression.
