The perversions are as follows: of royalty, tyranny; of aristocracy, oligarchy; of constitutional government, democracy.
Poverty is the parent of revolution and crime.
These, then, are the four kinds of royalty. First the monarchy of the heroic ages; this was exercised over voluntary subjects, but limited to certain functions; the king was a general and a judge, and had the control of religion The second is that of the barbarians, which is a hereditary despotic government in accordance with law. A third is the power of the so-called Aesynmete or Dictator; this is an elective tyranny. The fourth is the Lacedaemonian, which is in fact a generalship, hereditary and perpetual.
But since there is but one aim for the entire state, it follows that education must be one and the same for all, and that the responsibility for it must be a public one, not the private affair which it now is, each man looking after his own children and teaching them privately whatever private curriculum he thinks they ought to study.
A state is an association of similar persons whose aim is the best life possible. What is best is happiness, and to be happy is an active exercise of virtue and a complete employment of it.
The best political community is one where the middle class has control and is larger than both other classes.
A democracy when put to the strain grows weak, and is supplanted by Oligarchy.
. .we would have to say that hereditary succession is harmful. You may say the king, having sovereign power, will not in that case hand over to his children. But it is hard to believe that: it is a difficult achievement, which expects too much virtue of human nature.
Even if you must have regard to wealth, in order to secure leisure, yet it is surely a bad thing that the greatest offices, such as those of kings and generals, should be bought. The law which allows this abuse makes wealth of more account than virtue, and the whole state becomes avaricious.
So we must lay it down that the association which is a state exists not for the purpose of living together but for the sake of noble actions.
