From Ryszard Kapuscinski’s book Shah of Shahs (about the last Shah of Iran):
All books about all revolutions begin with a chapter that describes the decay of totterign authority or the misery and sufferings of the people. They should begin with a psychological chapter, one that shows how a harassed, terrified man suddenly breaks his terror, stops being afraid. This unusual process, sometimes accomplished in an instant like a shock or a lustration, demands illuminating. Man gets rid of fear and feels free. Without that there would be no revolution.
