Aristotle's theory of virtue is the community center on the personal virtue of the practice is a social practice, the development of human society to a certain stage only have a complete practice of virtue may be. The practice of virtue as a necessary part of being the center of play, happiness is in line with the real life of virtue. Different practical activities to develop a different virtue, do not have the virtue of professional practice may be impossible to cultivate virtue. The best city of all citizens have complete virtue city. But Aristotle seems that this is only an ideal state. The city should be based on reality as the standard of justice. Justice is the most basic social virtue, but justice can be used for two kinds of understanding, one embodiment of all virtue and social justice community as a whole, the second is part of the justice or the proportion of justice. Aristotle's theory of virtue is one kind of social theory which suggests, individual practice of virtue is social practice and advanced practice of virtue can be possible when human society has developed some high level. The necessary and center part of eudaimonia is virtual practice, and eudaimonia is virtual life. Different practical activities cultivate different virtues and in some occupations, the tendency of their practices is such that the people in the careers can not get vitures. The best city-state shall be the whole citizenship who have all important virtues. However , it is one kind of ideal situation. We shall by justice value the real city-state. Justice is basic social virtue, and we can understand it by two ways, one is said that justice represents the whole virtue and entire interest of community, and the other is said that justice is part justice and ratio justice
