The loyalty is to the community, or the “just city,” and not to the basic family structure that has built societies that have grown and flourished. Socrates’ breeding plan lowers mankind to the level of the beast.
The just city can not come into existence. The basic struggle will always be; whose justice will rule and will the just ruler, rule justly. Some consider Marx a philosopher, yet when his idea of a “just city” was put to the test millions died. The Founding Fathers, to some were philosophers, tried to create a shining city on the hill, but slavery continued, if you didn’t own property you couldn’t vote, presidents suspended the rights of citizens and, it seems at times, the powerful only have their best interests in mind. Unfortunately, if the “just city” came into existence the philosopher would give way to the tyrant. Man’s justice is imperfect and that is the reality we face.
