  Some readers answer Popper by staking out a diametrically opposed position (Vlastos 1977). They maintain that Plato conceives of the city’s good as nothing more than the aggregate good of all the citizens. On this view, citizens need to contribute to the city’s happiness only because they need to contribute to the happiness of other citizens if they are to achieve their own maximal happiness. Any totalitarian control of the citizens is paternalistic.  Yet this view, too, seems at odds with much of the Republic.  When Socrates says that the happiest city is a maximally unified city (462a–b), or when he insists that all the citizens need to be bound together (519e–520a), he seems to be invoking a conception of the city’s good that is not reducible to the aggregate good of the citizens.
