Rock, meet water: Kim Du Toit encounters a phenomenon that was known of thousands of years ago. Or, human nature rears its fugly head again:
When the great Tao ceased to be observed, benevolence (jen) and righteousness (i) came into fashion. Then wisdom and cleverness appeared, and hypocrisy followed at their heels. When harmony no longer prevailed among kin, loyal sons first appeared; when the states fell into disorder, loyal ministers appeared.
It begins, of course, with the notion that there is something wrong with people using things like "common sense" and reliance on standards of behavior to make their way through life. It ends with a woman letting a rapist into her house because it's rude to be suspicious of a strange man knocking on her door.
