These essays examine the relation of society and the state or, more broadly, the place of political action in society and in the history of Sung China. Connections between intellectual change and sociopolitical change are a consistent focus; attitudes toward history and problems of authority are a recurrent concern. The authors suggest new kinds of continuity between the disparate intellectual worlds of Northern and Southern Sung China. Their findings have important implications for our understanding of the neo-Confucian movement in Sung history and of the Sung in the history of Chinese ideas about politics and social action.
