Plato wrote the "Republic", the "Laws", and the "Statesman". The Republic says there will not be justice in cities unless they are ruled by philosopher kings; those who enforcing the laws should treat their women, children, and property in common; and the individual should tell noble lies to promote the common good. The "Republic" says that such a city is likely impossible as it thinks philosophers would refuse to rule and the people would refuse to be ruled by philosophers.
