Realism and liberalism are two prominent theories in international relations that offer different perspectives on the role of the state, international order, and power dynamics in world politics.
Realism is a theory that emphasizes the role of power and national interest in shaping international relations. According to realists, the international system is characterized by anarchy, meaning that there is no higher authority to enforce rules or resolve conflicts between states. As a result, states must rely on their own resources and power to protect their interests and ensure their survival. Realists also believe that states are motivated by self-interest and that they act rationally to maximize their power and security.
Liberalism, on the other hand, is a theory that emphasizes the role of international institutions, global governance, and cooperation in shaping international relations. According to liberals, the international system is not necessarily characterized by anarchy, and states can work together to achieve common goals and promote global welfare. Liberalism also places a strong emphasis on democracy, human rights, and the rule of law as important values that should shape international relations.
There are some key differences between realism and liberalism. Realism tends to view international relations as a zero-sum game, where one state's gain is another state's loss. This leads realists to prioritize national interest and the pursuit of power over other values such as human rights or global welfare. In contrast, liberals view international relations as a positive-sum game, where states can cooperate and work together to achieve mutual benefits. This leads liberals to prioritize values such as democracy, human rights, and global welfare over the pursuit of power.
Despite these differences, realism and liberalism are not mutually exclusive theories, and many international relations scholars adopt a mixed approach that incorporates elements of both theories. For example, some scholars argue that international institutions and cooperation can play a positive role in shaping international relations, but that these efforts must be grounded in a realistic assessment of power dynamics and national interests.
Overall, realism and liberalism offer different perspectives on the role of the state, international order, and power dynamics in world politics. While realism emphasizes the role of power and national interest, liberalism emphasizes the role of international institutions, global governance, and cooperation. Both theories have contributed important insights to our understanding of international relations and continue to shape the way we think about the world today.
