与原来的执政官不一样，经过培训与选拔出来的护卫者会终结党派之争。理由就是前面提到的“朋友事事、物物共享”，也就是对护卫者的安排。

At their coming the battles of party politics will be no more.
他们的到来，党派之争将不复存在。

The Story of Philosophy《哲学的故事》第1章Plato第7节VI. The Political Solution第6段第1句：

This arrangement will make it unprofitable, as well as dangerous, for the guardians to rule as a clique seeking the good of their class than that of the community as a whole. For they will be protected from want; the necessities and modest luxuries of a noble life will be theirs in regular provision, without the searing and wrinkling care of economic worry. But by the same token they will be precluded from cupidity and sordid ambitions; they will always have just so much of the world's goods, and no more; they will be like physicians establishing, and themselves accepting, a dietary for a nation. They will eat together, like consecrated men; they will sleep together, like soldiers sworn to simplicity. "Friends should have all things in common," as Pythagoras used to say (Laws 807). So the authority of the guardians will be sterilized, and their power made poison less; their sole reward will be honor and the sense of service to the group. And they will be such men as from the beginning have deliberately connected to so materially limited a career; and such men as at the end of their stern training will have learned to value the high repute of the statesman above the crass emoluments of the office-seeking politicians or the "economic man." At their coming the battles of party politics will be no more.
浙江大学译本： 随着他们掌控政权，党派政治间的你争我夺也将自然消逝。
