Fields and subfields of Political Science

Political science subfields include political theory, political philosophy, political ideology, political economy, policy studies and analysis, comparative politics, international relations, and a host of related fields.

• Domestic politics is generally the most common field of study; its subfields include public opinion, elections, national government, and state, local, or regional government.

• Comparative politics focuses on politics within countries (often grouped into world regions) and analyzes similarities and differences between countries.

• International relations considers the political relationships and interactions between countries, including the causes of war, the formation of foreign policy, international political economy, and the structures that increase or decrease the policy options available to governments. International relations are organized as a separate department in some universities (for example in V.N. Karazin Kharkiv National University is Department of international economic relations and tourist business).

• Political theory includes classical political philosophy and contemporary theoretical perspectives (e.g., constructivism, critical theory, and postmodernism).

• Public administration studies the role of the bureaucracy. It is the field most oriented toward practical applications within political science and is often organized as a separate department that prepares students for careers in the civil service.

• Public law studies constitutions, legal systems, civil rights, and criminal justice (now increasingly its own discipline).

• Public policy examines the passage and implementation of all types of government policies, particularly those related to civil rights, defense, health, education, economic growth, urban renewal, regional development, and environmental protection.

Political Science: origins, schools, historical heritage and development ancient influences

Analyses of politics appeared in ancient cultures in works by various thinkers, including Confucius (551 - 479 bc) in China and Kautilya (flourished 300 bc) in India. Writings by the historian Ibn Khaldun (1332 - 1406) in North Africa have greatly influenced the study of politics in the Arabic-speaking world. But the fullest explication of politics has been in the West. Some have identified Plato (428/427 - 348/347 bc), whose ideal of a stable republic still yields insights and metaphors, as the first political scientist, though most consider Aristotle (384 - 322 bc), who introduced empirical observation into the study of politics, to be the discipline’s true founder.

Aristotle’s students gathered descriptions of 158 Greek city-states, which Aristotle used to formulate his famous six fold typology of political systems. He distinguished political systems by the number of persons ruling (one, few, or many) and by whether the form was legitimate (rulers governing in the interests of all) or corrupt (rulers governing in their own interests). Legitimate systems included monarchy (rule by one), aristocracy (rule by the few), and polity (rule by the many), while corresponding corrupt forms were tyranny, oligarchy, and democracy. Aristotle considered democracy to be the worst form of government, though in his classification it meant mob rule. The best form of government, a polity, was, in contemporary terms, akin to an efficient, stable democracy. Aristotle presciently noted that a polity functions best if the middle class is large, a point confirmed by modern empirical findings. Aristotle’s classification endured for centuries and is still helpful in understanding political systems.

Plato and Aristotle focused on perfecting the polis (city-state), a tiny political entity, which for the Greeks meant both society and political system. The conquest of the Mediterranean world and beyond by Aristotle’s pupil Alexander the Great (336 - 323 bc) and, after his death, the division of his empire among his generals brought large new political forms, in which society and political system came to be seen as separate entities. This shift required a new understanding of politics. Hellenistic thinkers, especially the Stoics, asserted the existence of a natural law that applied to all human beings equally; this idea became the foundation of Roman legalism and Christian notions of equality (see Stoicism). Thus, the Roman orator Marcus Tullius Cicero (106 - 43 bc), who was strongly influenced by the Stoics, was noteworthy for his belief that all human beings, regardless of their wealth or citizenship, possessed an equal moral worth.

Early Christian thinkers, such as St. Augustine (354 - 430), emphasized the dual loyalty of Christians to both God and temporal rulers, with the clear implication that the “heavenly city” is more important and durable than the earthly one. With this came an otherworldly disdain for politics. For eight centuries knowledge of Aristotle was lost to Europe but preserved by Arab philosophers such as al-Fārābī (c. 878 - c. 950) and Averroes (1126 - 1198). Translations of Aristotle in Spain under the Moors revitalized European thought after about 1200. St. Thomas Aquinas (1224/25 - 1274) christianized Aristotle’s Politics to lend it moral purpose. Aquinas took from Aristotle the idea that humans are both rational and social, that states occur naturally, and that government can improve humans spiritually. Thus, Aquinas favored monarchy but despised tyranny, arguing that kingly authority should be limited by law and used for the common good.

The Italian poet and philosopher Dante (1265 - 1321) argued in De monarchia for a single world government. At the same time, the philosopher Marsilius of Padua (1280 - 1343), in “Defensor Pacis” (1324, “Defender of the Peace”), introduced secularization by elevating the state over the church as the originator of laws. For this, as well as for proposing those legislators are elected, Marsilius ranks as an important modernizer.
