Realism in International Relations

Realism is one of the dominant schools of thought in international relations theory, theoretically formalizing the Realpolitik statesmanship of early modern Europe. Although a highly diverse body of thought, it is unified by the belief that world politics is always and necessarily a field of conflict among actors pursuing power. The theories of realism are contrasted by the cooperative ideals of liberalism.

Realists can be divided into three classes based on their view of the essential causes of interstate conflict:

• Classical realists believe it follows from human nature;
• Neorealists attribute it to the dynamics of the anarchic state system;
• Neoclassical realists believe it results from both, in combination with

The existence of a number of onomatopoeic words in natural languages, that is, words whose phonetic form is an imitation of the original sound they refer to such as cuckoo, splash, crush, and hoot in English, backed up the view held by the naturalist school.

The Conventionalists' View on Meaning

Greek philosophers who argued for the conventionalist explanation viewed the relationship of naming... Continue reading "Semantic Theory: Naturalists vs. Conventionalists" »
