"As a judge, history also undermines the claims of leaders to omniscience. Dictators, perhaps because they know their own lies so well, have usually realized the power of history. Consequently, they have tried to rewrite, deny, or destroy the past. Robespierre in revolutionary France and Pol Pot in 1970s Cambodia each set out to start society from the beginning again. Robespierre’s new calendar and Pol Pot’s Year Zero were designed to erase the past and its suggestions that there were alternative ways of organizing society. The founder of China, the Qin Emperor, reportedly destroyed all the earlier histories, buried the scholars who might remember them, and wrote his own history. Successive dynasties were not as brutal but they, too, wrote their own histories of China’s past. Mao went one better: He tried to destroy all memories and all artifacts that, by reminding the Chinese people of the past, might prevent him from remodelling them into the new Communist men and women."
