Six Upright and Six Corrupt Ministers
Ministers are graded by how they relate to the ruler's errors and interests, not by talent. The upright types run from the sage minister, who foresees trouble and steers the ruler away before it forms, down to the loyal and the upright, who openly oppose error at risk to themselves. The corrupt types run from the time-server, who merely fills a post, through the flatterer who echoes the ruler's wishes, to the traitor who divides the court and the ruinous minister who leads the state to destruction.
