In the previous books Plato has described the ideal State; now he returns to the perverted or declining forms, on which he had lightly touched at the end of Book IV. These he describes in a succession of parallels between the individuals and the States, tracing the origin of either in the State or individual which has preceded them. He begins by asking the point at which he digressed; and is thus led shortly to recapitulate the substance of the three former books, which also contain a parallel of the philosopher and the State.
Of the first decline he gives no intelligible account; he would not have liked to admit the most probable causes of the fall of his ideal State, which to us would appear to be the impracticability of communism or the natural antagonism of the ruling and subject classes. He throws a veil of mystery over the origin of the decline, which he attributes to ignorance of the law of population. Of this law the famous geometrical figure or number is the expression. Like the ancients in general, he had no idea of the gradual perfectibility of man or of the education of the human race. His ideal was not to be attained in the course of ages, but was to spring in full armour from the head of the legislator. When good laws had been given, he thought only of the manner in which they were likely to be corrupted, or of how they might be filled up in detail or restored in accordance with their original spirit. He appears not to have reflected upon the full meaning of his own words, “In the brief space of human life, nothing great can be accomplished” (X 608 B); or again, as he afterwards says in the Laws (III 676), “Infinite time is the maker of cities.” The order of constitutions which is adopted by him represents an order of thought rather than a succession of time, and may be considered as the first attempt to frame a philosophy of history.
The first of these declining States is timocracy, or the government of soldiers and lovers of honour, which answers to the Spartan State; this is a government of force, in which education is not inspired by the Muses, but imposed by the law, and in which all the finer elements of organization have disappeared. The philosopher himself has lost the love of truth, and the soldier, who is of a simpler and honester nature, rules in his stead. The individual who answers to timocracy has some noticeable qualities. He is described as ill educated, but, like the Spartan, a lover of literature; and although he is a harsh master to his servants he has no natural superiority over them. His character is based upon a reaction against the circumstances of his father, who in a troubled city has retired from politics; and his mother, who is dissatisfied at her own position, is always urging him towards the life of political ambition. Such a character may have had this origin, and indeed Livy attributes the Licinian laws to a feminine jealousy of a similar kind (VII 34). But there is obviously no connection between the manner in which the timocratic State springs out of the ideal, and the mere accident by which the timocratic man is the son of a retired statesman.
The two next stages in the decline of constitutions have even less historical foundation. For there is no trace in Greek history of a polity like the Spartan or Cretan passing into an oligarchy of wealth, or of the oligarchy of wealth passing into a democracy. The order of history appears to be different; first, in the Homeric times there is the royal or patriarchal form of government, which a century or two later was succeeded by an oligarchy of birth rather than of wealth, and in which wealth was only the accident of the hereditary possession of land and power. Sometimes this oligarchical government gave way
