Modem scholarship on Mozi has established an interpretative tradition of equating Mobian with logic. The present study takes issue with this tradition, criticizing its failure to locate the tension between logic and rhetoric in the Mohist art of disputation. Indeed, when modern scholars draw a parallel between the Mohist practice of debate and Western logic, they generally do not take into account the tension between logic and rhetoric, either in the West or in Mobian. Overlooking this tension, Hu Shi thus reads the "Xiaoqu" chapter in Mozi as a treatise on logic. Drawing upon the history of logic and rhetoric's development in the West, the present paper attempts to reveal Hu's bias in emphasizing the elements of logic in his explication of "Xiaoqu." To counterbalance Hu's reading of "Xiaoqu" in logical terms, this paper further highlights the rhetorical function of pi, mou, yuan, tui, four strategies of argument discussed in "Xiaoqu." Pi, mou, yuan, tui are actually four methods of analogy that take advantage of superficial resemblance to influence one's judgment of the argument's logical validity. Exploring the convergence and divergence of logic and rhetoric in the Mohist "Xiaoqu," it is hoped that we can arrive at a better understanding of Mobian.
