Books: Republic, Statesman, Apology etc.

(Note: Below mentioned text is the thought of Plato, not of me.)

Ideal State: To make the human beings a perfect human being and to maintain peace and justice, an ideal state is required. An ideal state could be developed only with the division of society into three categories; ruling class (reason), warrior class (courage) and working class (appetite/desire).

Philosopher Ruler: A ruler/king should be philosopher or the philosopher should be made ruler. A philosopher king runs the state affairs with efficiency and effectively because of his wisdom.

Warrior Class: Physically strong men should be appointed to maintain law and order in the city state and to secure the city from outer attacks. Physically strong men make a powerful army.

Working Class: Professional working class should arrange the food for the society. So, that ruling and warrior class perform their duty with efficiency.

                Sources of corruption are mind, family and property. Education is the best tool for the mind to eliminate corruptness. For the ruler and warrior class, there will be no family and property. Communism of family and property for ruler and warrior class. State will fix mating seasons. Best of men will mate with best of women to get the best rulers and warriors in the future. There will be a large family of ruler and warrior class, and they will be the fathers of every child. Women have equal rights with men are equally capable to rule.

Justice Theory: An unjust person will become just and law-abiding in an ideal state. Each part of the state will perform its duty with efficiency and effectively, because they are capable for the duty. There will be no interference in others profession.
