This study examines the intertextuality of the Daodejing 道德經 and the Sunzi 孫子 by exploring one possible horizon that can shed light on the intellectual environment of their early circulations. A preliminary section examines the early doctrinal movements of what would later be recognized as Daoism and Militarism by triangulating them with the early doctrinal movements of what would later be recognized as Confucianism. This is followed by a consideration of the possible ways in which the early “authors” of the (...) Daodejing and the Sunzi honed their respective systems of thought by way of at least occasional encounter, dialogue, and debate with each other during the early period when their texts were still relatively fluid. The final sections provide a textual analysis of some of their shared content on the topics “surprise attack” and “straightforward attack,” and the “chaos” of cosmogony and battle. (shrink)
