All legal norms that govern society must be born from a higher legal norm. This legal norm for Indonesia is embodied in the Pancasila which prescribes the basic principles underlying the 1945 Constitution. The unifying function of the Pancasila is operationalized in the agreement to form a Unitary Republic of Indonesia (NKRI) whose motto "Bhinneka Tunggal Ika" expressly recognizes unity in diversity. The Pancasila has four pillars which in the constitutional history of Indonesia have become the subject of varying political interpretations to justify policies of incumbents. This paper will explore the normative concept of the four pillars and their influence on indonesia as a nation.
