Who Said That Political Theory Includes Political Science and Political Philosophy?


Vincent White

Political theory is an academic discipline that seeks to analyze and interpret political phenomena, including the nature of political power, the formation of political systems, and the principles that govern political behavior. Within this broad field, there are two major branches: political science and political philosophy. But who said that these two branches are included in political theory?

What is Political Science?
Political science is a branch of social science that deals with systems of governance, power, and politics. It involves the study of both national and international politics, including topics such as voting behavior, public opinion, and international relations. Political scientists use both quantitative and qualitative methods to analyze data, develop theories, and make predictions about political events.

What is Political Philosophy?
Political philosophy is a branch of philosophy that deals with fundamental questions about politics and society. It involves the study of concepts such as justice, liberty, equality, democracy, and authority. Political philosophers seek to understand the nature of government and its role in society by examining different theories about the origins of political power and the best ways to organize society.

How are Political Science and Political Philosophy Related to Political Theory?
Political theory encompasses both political science and political philosophy because it seeks to understand how power is exercised in society through both empirical observation (political science) and normative analysis (political philosophy). By studying both aspects of politics – how things are versus how they should be – political theory seeks to provide a comprehensive picture of how society functions.

The Origins of Political Theory

The origins of modern political theory can be traced back to ancient Greece. The Greek philosopher Plato wrote some of the earliest works on politics with his famous book “The Republic,” which explored questions about justice, democracy, and the nature of good governance. Aristotle also made significant contributions to political theory with his works on ethics (Nicomachean Ethics) as well as politics (Politics).

How Political Theory has Evolved

Over time, political theory has evolved and expanded to include a wide range of topics and perspectives. In the 17th century, political philosophers such as Thomas Hobbes and John Locke wrote works that explored the relationship between individuals and the state, including questions about the role of government in protecting citizens’ rights. In the 19th century, Karl Marx developed a theory of communism that viewed capitalism as an oppressive system that needed to be overthrown.

Today, political theory encompasses a wide range of topics and methodologies. Political scientists use statistical analysis to study voting patterns and public opinion, while political philosophers continue to explore questions about justice, democracy, and human rights.


While there is some debate about whether political science and political philosophy should be considered separate disciplines or branches of political theory, it is clear that both fields are essential for understanding how power is exercised in society. By analyzing both empirical data and normative principles, political theorists seek to provide a comprehensive understanding of how politics works – both in theory and practice.
