David Easton (political scientist)

David Easton was a prominent political scientist known for developing a systematic framework called the "systems theory" of politics. He viewed politics as a dynamic process involving the exchange of inputs (such as demands and supports from the public), which are processed within a political system through decision-making procedures, producing outputs (laws, policies). These outputs then influence the environment, generating new demands. His approach helps explain how political systems function, adapt, and maintain stability or change over time by analyzing interactions between society and government.
