Emile Durkheim was a French sociologist known as the father of functionalism. He argued that societies maintain order and stability through shared value systems that serve to integrate members and reinforce social norms. Durkheim analyzed differences between traditional and modern societies, finding traditional ones had stronger social cohesion through values of solidarity, while modern societies emphasized individualism more, risking anomie without consensus. He used suicide rates to show how social integration affects deviations from social norms.
