This is a famous proposition put forward by Aristotle, the founder of Western political science. This proposition is quoted as "Man is a political animal." This definition of human nature is the first and groundbreaking in the history of philosophy. What he means is that man must live a city-state life according to the requirements of his nature. Man cannot exist independently. Only through city-state life can man's nature be realized. People's good nature makes people constantly pursue a good life. According to his point of view, everything created by nature has a purpose. The purpose of human beings is to achieve the so-called three "good deeds", namely material wealth, physical health and good morality. Among them, good morality, that is, the goodness of the soul, is the most essential. Only when humans realize the goodness of their souls can they truly be different from animals and realize their nature. However, no isolated individual or small-scale social group can enable people to realize these three "good deeds". Only city-states can do this. Therefore, if people want to realize their own nature, they must become members of the city-state and pass through the city-state. Life.

Human beings are gregarious animals by nature and must live a gregarious life. Originally, a family was formed by the combination of male and female and master and slave. It was established by human beings to meet their daily needs. the basic form of society. Then, in order to meet broader needs, humans united several families to form village communities. The most natural form of village communities was tribes. Finally, several village communities united to form city-states. At this point, social organization has evolved to an advanced and complete state. Therefore, city-states are completely the product of natural evolution.

Aristotle believed that a city-state is a "supreme and extensive social group." Because human life can be completely self-sufficient within the scope of the city-state, and people's good deeds can be completed in the city-state. Although families and villages all have good as their purpose, the purpose of the city-state is the highest good, which is a "good life" for citizens. .

Gentiles had no political rights and could not participate in the political life of the city-state. The political life of citizens is above all else. ③In gatherings in the Greek world with the participation of multiple city-states, the public image of a citizen represents the city-state where he is located, and each city-state is also very concerned about the performance of its citizens.
