Aristotle’s methodology occupies a foundational place in the history of Western political thought. It represents one of the earliest systematic efforts to investigate political phenomena through reasoned inquiry, observation, and comparative analysis. Unlike his teacher Plato, who relied heavily on abstract reasoning and ideal forms, Aristotle grounded his method in empirical observation and practical realities. His approach was both analytical and teleological, seeking to understand the purposes of political institutions and the nature of human association within the polis. Through his methodological rigor, Aristotle laid the groundwork for political science as an empirical and normative discipline. Aristotle’s method begins with his conviction that all inquiry must start from what is known and observable. He insisted that knowledge of politics, like knowledge in any field, must proceed from experience to theory rather than the reverse. In his view, philosophy should not construct imaginary states but analyze the constitutions and institutions that exist in reality. Hence, in his major political treatise, the *Politics*, Aristotle examined and classified 158 constitutions of Greek city-states, seeking to identify the principles underlying their stability and decay. This comparative and empirical orientation marks a decisive departure from Plato’s speculative idealism. For Aristotle, the purpose of studying politics was not to discover an unattainable utopia but to discern the best possible political order achievable under given circumstances. Aristotle’s methodology is deeply intertwined with his conception of science (*epistēmē*) and practical reason (*phronēsis*). He divided knowledge into three kinds: theoretical, practical, and productive. Political science belongs to the realm of practical knowledge, which
