The word ‘value’ is used in two but interrelated senses. In the first sense, it is used by political actors for desirable or undesirable things such as, democracy, justice, freedom, power, etc. As such, origin, relevance, and interrelation among various values must be studied and analysed.

Systems analysis, which was influenced by the Austrian Canadian biologist Ludwig von Bertalanffy and the American sociologist Talcott Parsons (1902–79), is a broad descriptive theory of how the various parts and levels of a political system interact with each other.

Easton was renowned for his application of systems theory to political science, and for his definition of politics as the “authoritative allocation of value” in A Framework for Political Analysis and A Systems Analysis of Political Life, both published in 1965.

Political science broadly refers to the study of governments, public policies and political behavior both in the United States and abroad, according to the American Political Science Association.

Political science is a classical discipline that deals with the study of political phenomena. Its goal is to deepen human understanding of the forms and nature of political action and to develop theoretical tools for interpreting politically meaningful phenomena.

Ancient. The antecedents of Western politics can be traced back to the Socratic political philosophers, such as Aristotle (“The Father of Political Science”) (384–322 BC). Aristotle was one of the first people to give a working definition of political science.
