Functionalism:
This is one of the important sociological perspective and is also known as consensus theory.
Step-by-step explanation:
Functionalist perspective postulates that every aspect of society is responsible for its stability and proper functioning as each aspect or part of it is interdependent on other. Some of the sociologists who propagated this perspective were Emile Durkheim, Robert Merton and Talcott Parsons.
One example of functionalism is that government offers education to children of the country so that tomorrow that can support their near and dear ones and the funds which are used by government for providing education is the money of citizens only collected through taxes. So, here citizens and government are interdependent on each other.
