The discipline of political science is still too much influenced by the ideal of finding a method that will do for politics what Newton did for physics (as one author puts it). The quest for a “hard” science of political behavior that focuses on “facts” separated from “values” generally controls much if not most of the discipline. In this century-long quest, the discipline has imported assumptions and methods from sociology, psychology, mathematics, biology, economics, and other sciences in various attempts to achieve a cause-and-effect explanation of political behavior. This paper tries to expose the weakness and adequacy of these typically reductionist approaches to political science and outlines an approach that not only rejects modal reductionism but identifies the object of political science as the norm-responsive institutional community that is constituted by government and citizens (or subjects). The political community (or “state” as it is referred to throughout much of the world) is a norm-responsive entity that cannot be properly understood from the prejudicial point of view of a fact/value dichotomy. Instead, it must be recognized as an historically dynamic institution that functions in all modalities of human experience (physical, biotic, psychical, social, linguistic, logical, economic, juridical, ethical, and more) and is distinguishable from other institutions and organizations, such as the family, church, school, and business corporation. Political science, therefore, must be an entity science that entails multi-modal, normative analysis with full self-consciousness of its philosophical and religiously deep assumptions.
