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 a government not of the few but of the rich. And each class is thought of, not as trying to express an ideal, but as struggling to acquire power or maintain its position. If ever the class existed in unredeemed nakedness, it was in the Greek cities of the fourth century, and its existence is abundantly recognised by Aristotle. His account of the causes of revolutions in Book V. shows how far were the existing states of Greece from the ideal with which he starts. His analysis of the facts forces him to look upon them as the scene of struggling factions. The causes of revolutions are not described as primarily changes in the conception of the common good, but changes in the military or economic power of the several classes in the state. The aim which he sets before oligarchs or democracies is not the good life, but simple stability or permanence of the existing constitution.
With this spirit of realism which pervades Books IV., V., and VI. the idealism of Books I., II., VII., and VIII. is never reconciled. Aristotle is content to call existing constitutions perversions of the true form. But we cannot read the Politics without recognising and profiting from the insight into the nature of the state which is revealed throughout. Aristotle's failure does not lie in this, that he is both idealist and realist, but that he keeps these two tendencies too far apart. He thinks too much of his ideal state, as something to be reached once for all by knowledge, as a fixed type to which actual states approximate or from which they are perversions. But if we are to think of actual politics as intelligible in the light of the ideal, we must think of that ideal as progressively revealed in history, not as something to be discovered by turning our back on experience and having recourse to abstract reasoning. If we stretch forward from what exists to an ideal, it is to a better which may be in its turn transcended, not to a single immutable best. Aristotle found in the society of his time men who were not capable of political reflection, and who, as he thought, did their best work under superintendence. He therefore called them natural slaves. For, according to Aristotle, that is a man's natural condition in which he does his best work. But Aristotle also thinks of nature as something fixed and immutable; and therefore sanctions the institution of slavery, which assumes that what men are that they will always be, and sets up an artificial barrier to their ever becoming anything else. We see in Aristotle's defence of slavery how the conception of nature as the ideal can have a debasing influence upon views of practical politics. His high ideal of citizenship offers to those who can satisfy its claims the prospect of a fair life; those who fall short are deemed to be different in nature and shut out entirely from approach to the ideal.
