A longstanding orthodoxy holds that the Mohists regard the promotion of li (benefit, 利) as their ultimate normative criterion, meaning that they measure what is yi (just, 義) or buyi (unjust, 不義) depending on whether it maximizes li or not. This orthodoxy dates back at least to Joseph Edkins (1859), who saw Mozi as a utilitarian and an ally of Bentham. In this paper, we will argue that this orthodoxy should be reconsidered because it does not square with several passages from the Mozi. That the Mohists place a strong weight on the promotion of ‘li for the whole world (tianxia zhi li, 天下之利)’ is uncontroversial. We argue, however, that in certain cases the Mohist moral calculus diverges in its rationale or outcome from li-promotionalism. This position rejects the orthodoxy by showing that Mohism and li-promotionalism are not entirely coterminous.

The Mohists develop the concept of yi 義 to denote what is morally right in a normative sense. We argue that this concept has, as one of its necessary conditions, a requirement to not harm others. Additionally, we will show that the motivation of developing this concept is that it can be both universalized and publicly agreed upon, thus serving the Mohists’ endeavor to overcome human conflicts that make the world chaotic and unlivable. We argue therefore that the Mohist notion of gongyi 公義 is best captured by the requirement of “not harming.” Moreover, we shall show that the Mohists themselves committed to this requirement as the first principle of all their core doctrines. Finally, we argue that due to the justifiability and universalizability of the requirement of “not harming,” the Mohists’ commitment to it as a prerequisite normatively justifies their other values in a way that was unprecedented at the time.
