It still would be years before I understood the seriousness of my change of view. Much later, I recognized it in "Revolution," the essay of Polish journalist Ryszard Kapuscinski, who describes the moment when a man on the edge of a crowd looks back defiantly at a policeman — and when that policeman senses a sudden refusal to accept his defining gaze — as the imperceptible moment in which rebellion is born. "All books about all revolutions begin with a chapter that describes the decay of tottering authority or the misery and sufferings of the people," Kapuscinski writes. "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 — demands to be illustrated. Man gets rid of fear and feel free. Without that, there would be no revolution.
