Abstract

Asking the question of the usefulness of sociology leads us to question the roles, missions and postures that will give social scientists to advance their knowledge about situations and social facts. Among these positions, we want to mention in particular the sociologist practitioner claiming the sociology of intervention. The sociology of intervention is a practical discipline leading sociologist to immerse themselves in a local situation to improve it. Acting as a third party, the sociologist intervention takes place between individuals to help them better manage their community life. By bringing as much as possible academic knowledge and popular knowledge, it contributes to the well-being of individuals in their community life. The sociologist raises the question of his usefulness.
