“Let the other societies take the skilled, the hopefuls, the ambitious, the self-confident. He’d take the whining resentful ones, the ones with a bellyful of spite and bile, the ones who knew they could make it big if only they’d been given the chance. Give him the ones in which the floods of venom and vindictiveness were dammed up behind thin walls of ineptitude and lowgrade paranoia. And stupidity, too. They’ve all sworn the oath, he thought, but not a man jack of ’em has even asked what a figgin is.”
