  In fact, Socrates expresses several central political theses in the  Republic that appear in other Platonic dialogues, as well,  especially in the Gorgias, Statesman, and  Laws. First, the best rulers are wise. Second, the best rulers rule for the benefit of the ruled, and not for their own sake. Third, a city is highly unlikely to have the best rulers, in part because there is a gulf between the values of most people and the values of the wise. Fourth, the greatest harm to a city is disagreement about who should rule, since competing factions create civil strife.  So, fifth, a central goal of politics is harmony or agreement among the citizens about who should rule. Last, harmony requires that the city cultivate virtue and the rule of law. The consistency of these messages across several Platonic dialogues might well make us so bold as to think that they are the take-home message of the Republic’s politics.
