To the surprise of the auditors, Socrates concedes to Adeimantus' statement. But, Socrates continues (at this point he argues a parable of a ship's pilot and his crew), it is the state's own fault that it fails to discern the value of philosophers. In its present condition, no one in the state respects what the philosopher alone possesses: knowledge and wisdom. The present and past politicians in the state as it exists are "successful" simply because they flatter the public as if the public were some "monster" or some "great beast" the politicians can feed to surfeit or cajole through flatteries of various sorts to contain it. We have all seen politicians in the political arena; these politicians have learned nothing except to shout with the loudest crowd; these politicians say one thing and do another. They are duplicitous because they have to be, given the caliber of the society in which they find themselves. So of course such a society, such a public, has no use for a good philosopher.
As for the bad philosophers, the rogues, they have become that way because their society has corrupted them. In a good state, intent on being good, a young developing philosopher might become good and wise. In a bad society, like the one in which this dialogue is taking place, the young philosopher, having become corrupt, becomes subject to the flatteries and ambitions of his fellow citizens, who flatter him in the hopes of realizing their ambitions. In fact, in a bad society, the more intelligent a young philosopher is, the more attractive he becomes to people who want to use him, and the more such people corrupt him. So things go from bad to worse: Because of his public popularity and the flatteries he has accepted, the young philosopher becomes arrogant. Thus the young philosopher will forego philosophy, or he will use some of its attributes for evil purposes. He will become self-seeking and self-congratulatory. Yes, some philosophers are bad men, rogues.
At the same time, although good philosophers are useless to a bad state (Plato's view of his society), there may come a day when a good philosopher might become a ruler, which Socrates has advocated in his argument and in its conclusions. Or the day may come when a ruler in political power might become a philosopher. This would be the only case in which we might realize the Ideal State.
