Incremental reforms, evolving out of trial-and-error experience, may over the course of time amount to a profound change in society, but this is wholly different from the kind of sweepingly imposed prepackaged changes to smite the wicked and exalt the anointed, in keeping with the invidious and dramatic vision of the intellectuals. That vision requires villains, whether individuals or groups or a whole society permeated by wrong ideas that can be corrected by those with right ideas.
