  A similar conclusion, although derived in a traditional way, comes from the non-positivist theorists of the English school (International Society approach) who emphasize both systemic and normative constraints on the behavior of states. Referring to the classical view of the human being as an individual that is basically social and rational, capable of cooperating and learning from past experiences, these theorists emphasize that states, like individuals, have legitimate interests that others can recognize and respect, and that they can recognize the general advantages of observing a principle of reciprocity in their mutual relations (Jackson and Sørensen 167). Therefore, states can bind themselves to other states by treaties and develop some common values with other states. Hence, the structure of the international system is not unchangeable as the neorealists claim. It is not a permanent Hobbesian anarchy, permeated by the danger of war. An anarchic international system based on pure power relations among actors can evolve into a more cooperative and peaceful international society, in which state behavior is shaped by commonly shared values and norms. A practical expression of international society are international organizations that uphold the rule of law in international relations, especially the UN.
