Abstract

This article offers a critical overview of a set of normative theories, namely Tianxia 天下 (all-under-heaven), whose purpose is to provide a renewed conceptual framework for the improvement of the world system. First, the article introduces the origins, main features, and differences within Tianxia, before discussing two major criticisms leveled against it. The article then argues that the most powerful parts of these criticisms come from the challenges posed against Tianxia’s legitimacy. The article elaborates on this and introduces two additional challenges of the same kind which were not discussed before. While the article leaves open the question of whether Tianxia is a realistic utopia, it insists that meaningful discussion of Tianxia must take legitimacy challenges seriously. It ends with a discussion concerning whether China can be understood as a civilization-state and how this understanding affects Tianxia’s reception as a realistic utopia.
