This article aims to provide a systematic framework for understanding political philosophy by delineating its structure into three primary domains: metapolitical philosophy, political philosophy, and applied political philosophy. The first section, metapolitical philosophy, explores the foundational questions about the nature, epistemology, axiology, ethics, logic, ontology, and aesthetics of political philosophy. The second section, political philosophy, examines both normative and descriptive approaches, including ethical, logical, and ontological dimensions of political systems. The third section, applied political philosophy, addresses concrete issues such as biopolitics, political ecology, and digital political etiquette.
