Virtually all Chinese historians, past and present, have viewed the Duke of Zhou as a paragon of the virtuous minister. However, in traditional Chinese sources concerning the Duke of Zhou there is also a distinct negative undercurrent, several texts recording that the Duke “resided in the east” in contexts implying that he went into a sort of exile. Given this ambivalence in the history and traditions regarding the Duke of Zhou, the author examines two chapters of the Book of Documents: the “Shao gao” or “Announcement of the Duke of Shao” and the “Jun Shi” or “Lord Shi.” He posits that these two chapters represent two sides of a debate over political theory and governance. The “Jun Shi,” a speech by the Duke of Zhou to the Duke of Shao, expounds a political theory that privileges ministers over kings. The “Shao gao,” on the other hand, is an address by the Duke of Shao to the Duke of Zhou in which the Duke of Shao resolutely supports the king's prerogative to rule as the “eldest son” of Heaven.
This debate between the Duke of Zhou and the Duke of Shao was but the first instance of a tension that would continue to occupy statesmen and political theorists throughout Chinese history: between the power of the king or emperor and that of his ministers. While, in later times, neither side was ever able long to maintain supremacy in this debate, in the early Western Zhou the Duke of Shao almost certainly prevailed; shortly after the Duke of Shao made the address contained in the “Shao gao,” the Duke of Zhou first relinquished power to King Cheng and then, somewhat later, went into exile or retreat, never again to play a central role in Western Zhou government.
