Education shall be universal, but not compulsory, that is, all shall be taught, but not compelled to learn. Education shall be made attractive, almost a form of government.[V-70] The laws of imitation shall be utilized. The tutor shall carry out his teachings in practice.[V-71] A well-trained individual is a replica of a just society. Plato draws a parallelism, which is inaccurate, between the three classes in society and three traits of the individual. The rulers, soldiers, and artisans are compared respectively to the reason, the spirit, and the passions of the individual. The passions must be subordinated to the spirit, and both must be controlled by reason. The result will be a just individual.[V-72] In society a similar hierarchal relation shall hold between the rulers, soldiers, and artisans. The fundamental aim in education shall be to secure a change in the attitudes of people. Such changes are more important than modification in external matters. Thus, according to Plato, the divine foundations of a state are laid in education. Religion plays a basic rôle in the ideal Republic. Plato held that belief in God superseded in importance the doctrine that might is right. Impiety undermines the strength of the social kingdom. God created the individual for the whole, but not the whole for the individual. The worship of God is necessary for the individual in order to prevent him from reverting to selfishness and from making his humanitarian beliefs purely egoistic phenomena. Inasmuch as Plato outlined at the start a perfect republic, any change would likely constitute a deterioration. But even an ideal state is not immune to the entry of destructive ideas. The wise men, the rulers, are not proof against the temptations of absolute power. To remove the stirrings of self-interest in the minds of the guardians, Plato planned a communistic order. He overlooked, however, the weaknesses of communism, but these were pointed out at a later time by Aristotle. In spite of excellent safeguards the wisdom of the best rulers will occasionally fail them. Sooner or later they will err. In examining the youth they will allow warrior youth to be trained for the guardian class. With their spirit of contention and of ambition for honor these adventitious guardians will start the perfect state upon the downward road.[V-74] When the rulers seek personal power and honor, the ideal republic will be superseded by a timocracy. In a timocracy the ruler with the most private wealth will possess the greatest personal power and receive the highest honor. Moreover, other persons will be stimulated, thereby, to acquire wealth and power. In the meantime the masses will lose nearly everything. The result is an oligarchy in which the wealthy are honored and made rulers.[V-75] The poor are treated with dishonor and deprived of position.
