1. Law of Correlativity

Every created being has within itself two elements which form a correlative relationship. They are the principal element and the subordinate element. Also, each individual being externally forms another correlative relationship of subject and object between itself and another individual being, whereby it exists and develops. Living beings exist, multiply, and develop through such relationships. The formation of a relationship of subject and object means that they face each other; namely, that they are related with each other. Subject and object are related to each other either with or without a common purpose. When subject and object form a reciprocal relationship with a common purpose, it is said that they form a “correlative standard.” The fact that an individual being necessarily engages in a correlative relationship of subject and object with another being is called the “law of correlativity.” Accordingly, the first requirement a society (or historical process) must fulfill in order to develop is that correlative elements (correlatives) of subject and object must form a correlative relationship in every field, such as politics, economy, culture, and science. No development can take place without correlative relationships. Correlative elements of subject and object refer to Sungsang and Hyungsang, yang and yin, or principal and subordinate elements (or principal and subordinate beings). Examples of correlatives are spirit and body (mind and body), ideology and economic conditions (material conditions), spiritual culture and material civilization, government and people, managers and workers, workers and instruments of production, principal parts and subordinate parts in a machine, and so on. There are many other examples. As these correlative elements engage in the relationship of subject and object, development is achieved in all fields such as politics, economy, culture, science, and so on.
