Is there evidence of constitutionalism in classical Confucian political thought? In Sungmoon Kim's book on Confucian virtue politics, he argues that that Mencius (Mengzi, fourth century BCE) and Xunzi (third century BCE) are constitutionalists in the following sense: they expressed a commitment to creating durable institutions, one of whose primary aims is to constrain the exercise of legitimate political authority and facilitate good and proper uses of political authority. But for many political thinkers, the sort of constitutionalism that really matters (...) is the sort that entails a commitment to "constitutional remedies." Roughly, a constitutional remedy is some sanctioned means of enforcing the constraints or correcting political authorities who fail to abide by them. Moreover, it is often thought that the remedies should be entrenched – that is, widely recognized and regarded as beyond the legitimate power of the political authorities to change easily. Most decent political thinkers are constitutionalists in the the weak sense that they think there should be durable institutions that constrain abuses of power and facilitate good uses of power. Fewer go so far as to say that there should be entrenched checks and balances on that power, so that people's well-founded objections have something more than just rhetorical force against abuses of power. -/- In this paper, I examine whether Mencius and Xunzi would qualify as constitutionalists in the robust sense that presupposes entrenched remedies. I find that Mencius has some political commitments that might make him friendlier to aristocratic remedies than to democratic ones, but that his reluctance to divide political authority among non-ideal agents makes it difficult to know whether he would accept constitutional remedies of any sort. And my findings with respect to Xunzi are similar, but a modicum more hopeful: at best, Xunzi could be stretched to underwrite some aristocratic constitutional remedies, and he seems somewhat more open to dividing power among non-ideal agents. Neither Mencius nor Xunzi were robust constitutionalists, but it is historically and philosophically informative to ask how near they came to robust constitutionalism, and in which respects they fell short of it. -/- In the course of developing and justifying my interpretation, I call attention to two considerations in assessing an historical thinker's commitment to robust constitutionalism: first, whether the thinker invokes the threat of rebellion as a way of countenancing it or merely as a descriptive claim about likely consequences of bad governance; second, whether non-ideal political agents are empowered to check abuses of power. Only when the thinker actually countenances rebellion and allows that non-ideal political agents can check abuses can the thinker be plausibly described as a robust constitutionalist. (shrink)
