Platos ideal regime achieves justice by controlling individuals and their desires by setting down a compact to not tolerate injustice or suffering. By setting down laws and compacts and to name what the law commands lawful and just.(Bloom,359a).
Plato believed that even individuals who practice justice are forced to do it from the inability to do injustice due to fears of punishment. Plato felt that a democracy or rule of the people gave each man, both just and unjust, license to do whatever they wanted. While he felt that the law of a strong form of government would force men to honor the laws equally. Plato believed that justice was the advantage of the stronger, which to him was the control of the ruling body of the city by being master over the people and punishing any who broke the laws set down by the regime.(Bloom,338e-339a) Plato to believed that education and rearing of the ruler of the city or regime would create a perfect and just man. And he felt that the ruler must be older, while the ruled younger. Age is something that gives his perfect regime more control than one based on wisdom. He.
thought that the philosopher should be seen as the father, over the younger people of the city. He also feels that old men are afraid of death, and therefore less likely to risk torment in the afterlife by having selfish desires, such as for money. He believed that men would obey the laws in hopes of rewards and fear of punishment in this life and the next. He believed that the ruling regime must be most skilled at guarding the city with the interest of the city in their convictions. Plato believed that the regime once started, will roll on like a circle in its growth because of sound rearing and education producing good and sound natured offspring to carry on the order.(424a) He wanted a city ruled by philosophic class. He believed that when a ruler sets down the laws and practices that citizens would follow them.
