what does " non-philosophers" mean in this context???

[translation]

This leads to the difficulty that the philosophers will be ruled by the gentlemen, i.e., by their inferiors. One can solve this difficulty by assuming that the philosophers are not as such a constitutent part of the city. In other words, the only teachers who are as such a constituent part of the city are the priests. The end of the city is then not the same as the end of philosophy. If the gentlemen represent the city at its best, one must say that the end of the gentleman is not the same as the end of the philosopher. What was observed regarding the gentleman in his relation to the vulgar applies even more to the philosopher in his relation to the gentlemen and a fortiori to all other non-philosophers: the philosopher and the non-philosophers cannot have genuinely common deliberations.
