after something he knew not what. If primitive society is understood in the light of the state, the state is understood in the light of its most perfect form, when the good after which all societies are seeking is realised in its perfection. Hence for Aristotle as for Plato, the natural state or the state as such is the ideal state, and the ideal state is the starting-point of political inquiry.
In accordance with the same line of thought, imperfect states, although called perversions, are regarded by Aristotle as the result rather of misconception and ignorance than of perverse will. They all represent, he says, some kind of justice. Oligarchs and democrats go wrong in their conception of the good. They have come short of the perfect state through misunderstanding of the end or through ignorance of the proper means to the end. But if they are states at all, they embody some common conception of the good, some common aspirations of all their members.
The Greek doctrine that the essence of the state consists in community of purpose is the counterpart of the notion often held in modern times that the essence of the state is force. The existence of force is for Plato and Aristotle a sign not of the state but of the state's failure. It comes from the struggle between conflicting misconceptions of the good. In so far as men conceive the good rightly they are united. The state represents their common agreement, force their failure to make that agreement complete. The cure, therefore, of political ills is knowledge of the good life, and the statesman is he who has such knowledge, for that alone can give men what they are always seeking.
If the state is the organisation of men seeking a common good, power and political position must be given to those who can forward this end. This is the principle expressed in Aristotle's account of political justice, the principle of "tools to those who can use them." As the aim of the state is differently conceived, the qualifications for government will vary. In the ideal state power will be given to the man with most knowledge of the good; in other states to the men who are most truly capable of achieving that end which the citizens have set themselves to pursue. The justest distribution of political power is that in which there is least waste of political ability.
Further, the belief that the constitution of a state is only the outward expression of the common aspirations and beliefs of its members, explains the paramount political importance which Aristotle assigns to education. It is the great instrument by which the legislator can ensure that the future citizens of his state will share those common beliefs which make the state possible. The Greeks with their small states had a far clearer apprehension than we can have of the dependence of a constitution upon the people who have to work it.
Such is in brief the attitude in which Aristotle approaches political problems, but in working out its application to men and institutions as they are, Aristotle admits certain compromises which are not really consistent with it.
1. Aristotle thinks of membership of a state as community in pursuit of the good. He wishes to confine membership in it to those who are capable of that pursuit in the highest and most explicit manner. His citizens, therefore, must be men of leisure, capable of rational thought upon the end of life. He does not recognise the significance of that less conscious but deep-seated membership of the state which finds its expression in loyalty and patriotism. His definition of citizen includes only a small part of the population of any Greek city. He is forced to admit that the state is not possible without the co-operation of men whom he will not admit to membership in it, either because they are not capable of sufficient rational appreciation of political ends, like the barbarians whom he thought were natural slaves, or because the leisure necessary for citizenship can only be gained by the work of the artisans who by that very work make themselves incapable of the life which they make possible for others. "The artisan only attains excellence in proportion as he becomes a slave," and the slave is only a living instrument of the good life. He exists for the state, but the state does not exist for him.
2. Aristotle in his account of the ideal state seems to waver between two ideals. There is the ideal of an aristocracy and the ideal of what he calls constitutional government, a mixed constitution. The principle of "tools to those who can use them" ought to lead him, as it does Plato, to an aristocracy. Those who have complete knowledge of the good must be few, and therefore Plato gave entire power in his state into the hands of the small minority of philosopher guardians. It is in accordance with this principle that Aristotle holds that kingship is the proper form of government when there is in the state one man of transcendent virtue. At the same time, Aristotle always holds that absolute government is not properly political, that government is not like the rule of a shepherd over his sheep, but the rule of equals over equals. He admits that the democrats are right in insisting that equality is a necessary element in the state, though he thinks they do not admit the importance of other equally necessary elements. Hence he comes to say that ruling and being ruled over by turns is an essential feature of constitutional government, which he admits as an alternative to aristocracy. The end of the state, which is to be the standard of the distribution of political power, is conceived sometimes as a good for the apprehension and attainment of which "virtue" is necessary and sufficient (this is the principle of aristocracy), and sometimes as a more complex good, which needs for its attainment not only "virtue" but wealth and equality. This latter conception is the principle on which the mixed constitution is based. This in its distribution of political power gives some weight to "virtue," some to wealth, and some to mere number. But the principle of "ruling and being ruled by turns" is not really compatible with an unmodified principle of "tools to those who can use them." Aristotle is right in seeing that political government demands equality, not in the sense that all members of the state should be equal in ability or should have equal power, but in the sense that none of them can properly be regarded simply as tools with which the legislator works, that each has a right to say what will be made of his own life. The analogy between the legislator and the craftsman on which Plato insists, breaks down because the legislator is dealing with men like himself, men who can to some extent conceive their own end in life and cannot be treated merely as means to the end of the legislator. The sense of the value of "ruling and being ruled in turn" is derived from the experience that the ruler may use his power to subordinate the lives of the citizens of the state not to the common good but to his own private purposes. In modern terms, it is a simple, rough-and-ready attempt to solve that constant problem of politics, how efficient government is to be combined with popular control. This problem arises from the imperfection of human nature, apparent in rulers as well as in ruled, and if the principle which attempts to solve it be admitted as a principle of importance in the formation of the best constitution, then the starting-point of politics will be man's actual imperfection, not his ideal nature. Instead, then, of beginning with a state which would express man's ideal nature, and adapting it as well as may be to man's actual shortcomings from that ideal, we must recognise that the state and all political machinery are as much the expression of man's weakness as of his ideal possibilities. The state is possible only because men have common aspirations, but government, and political power, the existence of officials who are given authority to act in the name of the whole state, are necessary because men's community is imperfect, because man's social nature expresses itself in conflicting ways, in the clash of interests, the rivalry of parties, and the struggle of classes, instead of in the united seeking after a common good. Plato and Aristotle were familiar with the legislator who was called in by the whole people, and they tended therefore to take the general will or common consent of the people for granted. Most political questions are concerned with the construction and expression of the general will, and with attempts to ensure that the political machinery made to express the general will shall not be exploited for private or sectional ends.
Aristotle's mixed constitution springs from a recognition of sectional interests in the state. For the proper relation between the claims of "virtue," wealth, and numbers is to be based not upon their relative importance in the good life, but upon the strength of the parties which they represent. The mixed constitution is practicable in a state where the middle class is strong, as only the middle class can mediate between the rich and the poor. The mixed constitution will be stable if it represents the actual balance of power between different classes in the state. When we come to Aristotle's analysis of existing constitutions, we find that while he regards them as imperfect approximations to the ideal, he also thinks of them as the result of the struggle between classes. Democracy, he explains, is the government not of the many but of the poor; oligarchy
