Awareness of corruption implies the possibility of a sense of shame or, at least, of public revulsion. It is a far more critical matter when people don’t even know their rotten behaviour is dishonest, when they think of it as either their due or an acceptable custom. So it was undoubtedly with no sense of irony that President Jacob Zuma recently warned an African National Congress (ANC) meeting against "the enemy within". He denounced ill-discipline, factionalism and corruption, warning: "The enemy is always present … in different guises, sizes and shapes." The embodiment of those iniquities is, flagrantly, Zuma himself.
