Scope of IR
Initially the study of diplomacy, later expanded to include international law, international organizations, and the study of political actors and groups
IR is heavily dependent on other disciplines and has failed to develop a coherent body of knowledge
IR is in its infancy as a science, still a mixture of philosophy and history with unstable theories
Importance of IR
Understanding the motives of individual states and problems faced by the world, demonstrating that traditional sovereignty is outdated, and teaching that peace can only be achieved by solving global problems
Idealism
An approach that holds that old, harmful modes of behaviour like war and violence should be abandoned in favour of new ways determined by knowledge, reason, compassion and self-restraint
Idealist approach
Advocates morality and moral values as the means for securing the objective of making the world an ideal world, free from war, inequality, despotism, tyranny, violence and force
Realism
Regards politics as a struggle for power, seeks to explain international relations with factors like power, security and national interest, and sees prudence as the guide in politics
IR is broader than just the study of diplomacy, and includes a wide variety of political, non-political, official and unofficial, formal and informal activities and relations
