ABSTRACT: Deals with the issue of incommensurability between paradigms of International Relations through a scientific theory perspective. By asking the question of Water as a commodity is a positive means for poverty alleviation? we find incommensurability between the Pluralist and the Structuralist paradigms. By treating different epistemological perspectives in a hierarchical way, which marginalises certain branches of the discipline, information that could be used in a complementary analysis is lost. Instead of accepting incommensurability we therefore suggest that incommensurability should be treated as anomalies on the structural level of the discipline.
