This paper is an attempt to reconsider the legacy of universalism of traditional empires from the perspective of systems theory. In the West, the system ideas were already present in ancient Greek/Roman philosophy and developed further since the Renaissance within the domain of natural sciences (anatomy, mechanics or astronomy), whereas they did not develop as much in social sciences and particularly in politics, which lacks a holistic understanding. In the universal empires of the East (such as Iran, China and Russia) the system paradigm developed from the political life of centralized statehood. The core concept of the traditional imperial universalism was a particular understanding of “justice”, not as equality or absence of coercion, but as a certain form of social order. As the Chinese philosopher Xunzi and the Persian philosopher Nasir al-Din al-Tusi, noted, “justice” is primarily an “equilibrium”, that is a way of maintaining optimal interrelationships between different aspects of society within a single political whole. Traditional imperial universalism understood “just order” as a centralized hierarchical order. However, the current state of the systems approach and the complexity theory allows the reconsideration of the legacy of traditional universalism as the principle of totality of organizational connections and hierarchies of “systemic elements”, in the terminology of Russian philosopher, Alexander Bogdanov. It is concluded that the three Eastern thinkers share similar systematic understanding of “justice” as a hierarchically-arranged political order, coordinated on the basis of a single plan, which permits to maintain a dynamic balance.
