Explanation: Durkheim defines social fact as the social and cultural instruments that determine the ways of acting, thinking and feeling in an individual's life. Thus, the social fact forces you to adapt to the rules of society.
The social fact is the real agents or the set of ways that are at the center of a society.
Durkheim's central thesis points out that the social fact is in the individual's perception. This will be conditioned by social realities that impose the limits of behavior to be accepted by society.
