The insistent, modest, meticulous voice of history which Yu developed in these studies was the one he used in the debates over democracy in the 1980s and 1990s. Some people, including both the defenders of the state in Beijing and western modernization liberals, still insisted that democracy and Confucianism were incompatible. But Yu developed the philosophical and historical arguments perhaps implicit in the thought of his mentors: liberal Confucian values, once freed from the imperial ideology of the dynasties, are essential to democracy: The independent spirit of the scholar both models and creates responsible criticism of politics. Confucian values had always insisted on the critique of political power, moral judgment grounded in historic comparison, the voice of the people in governance, the contingent nature of the political mandate, public discourse, the responsibility of the individual for social action, and could even be developed for a contemporary view of women's rights.
