Scholars today discuss international law from various methodological angles. This Article aims to add perspectives from cognitive science, namely cognitive sociology and cognitive linguistics, or, to be more precise, cognitive pragmatics. It briefly elaborates on these fields’ respective approaches, benefits, and limits. To clearly delineate the usefulness of the methodologies, this Article separately applies both approaches to the same example of a process of interpretation in international law. This Article concludes that the two cognitive approaches can help lawyers better understand and implement international law. This not only provides a description of the process of interpretation, but will hopefully enable a better practice of international law.
