Like the child, the woman imagines good and evil in simple storybook images; Manichaeism reassures the mind by eliminating the anguish of choice; deciding between one scourge and a lesser one, between a benefit today and a greater benefit tomorrow, having to define by oneself what is defeat and what is victory: this means taking terrible risks; for the Manichaean, the wheat is clearly distinguishable from the chaff, and the chaff has to be eliminated; dust condemns itself, and cleanliness is the absolute absence of filth; cleaning means getting rid of waste and mud.
