Final answer:
The community of women and children is good for the guardian class because it prevents corruption and ensures equality and justice. It is not recommended for the other classes as it encourages strong family bonds outside of the guardian class.
Step-by-step explanation:
The community of women and children is considered good for the guardian class but not recommended for the other classes in the city for several reasons.
The first reason is that it prevents the corruption of the guardian class by familial ties. By living communally and holding children and property in common, the guardians are removed from the influence of family relationships, which could potentially lead to favoritism, conflicts of interest, and corruption.
The second reason is that it ensures equality and justice within the guardian class. By having a shared community, all guardians have equal access to resources and opportunities, eliminating any advantage or privilege that might come from individual family backgrounds.
Lastly, it encourages strong family bonds within the other classes. By not extending the communal living arrangement to the other classes, Plato promotes the importance of family and the nurturing of strong family bonds outside of the guardian class.
