"An invisible dictator, whose voice is audible always and everywhere giving directions, treats his subjects, whom he addresses as 'patients and criminals,' as a strict but just teacher would treat badly behaved louts. He is concerned mainly with uniformity and the elimination of envy. Pretty women are seen as a disruptive element. Thus it is virtually the moral duty of anyone born wih an 'Alpha' [attractive] face to undergo an operation in norder to acquire a 'Beta' [ordinary] face."
It turns out that the dictator is actually an old woman.
