He says, "Moreover, it is just to say here too, as I said there, that if the guardian attempts to become happy in such a way that he is no longer a guardian, and such a moderate, steady, and best life won't satisfy him; but, if a foolish adolescent opinion about happiness gets hold of him, it will drive him to appropriate everything in the city with his power, and he"ll learn that Hesiod was really wise when he said that somehow "the half is more than the whole""( Plato, 145-46). Socrates wants to deny any guardian the basic right to private property. He believes their happiness should come from the simple act of being the guardian. Anything else would stand in the way of doing his or her job. .
Socrates lays down certain roles that apply for the procreation in the city. The goal Socrates is trying to accomplish is to make the finest groups of people within the city as the guardians. He explains part of this by saying, "On the basis of what has been agreed, there is a need for the best men to have intercourse as often as possible with the best women, and the reverse for the most ordinary men with the most ordinary women; and the offspring of the former must be reared buy not that of the others, if the flock is going to be of the most eminent quality. And all this must come to pass without being noticed by anyone except the rulers themselves if the guardians" herd is to be as free as possible from fraction."(Plato, 138). The people of the city may only have relations with their own group and the rulers must approve that. This is also to make sure people may only have sex in their prime years. "A women, beginning with her twentieth year, bears for the city up to her fortieth; and a man, beginning from the time when he passes his swiftest prime at running, begets for the city u to his fifty fifth year"(Plato, 140). Plato is trying to clarify the certain ages which men and women are when they are in their prime to reproduce with others.
