This division of labor enables each of us to do what we do best, thereby increasing our productivity. Adam Smith wrote about the economic causes and consequences of an increasing division of labor. Durkheim wrote about the social causes and consequences of an increasing division of labor. He said that the division of labor determines social solidarity which determines collective conscience. The division of labor is the variety of jobs in a given society.
Social solidarity is the basis of people's solidarity or togetherness.
The collective conscience is the totality of beliefs and sentiments common to citizens in a society. According to Durkheim, deviance increases and law enforcement changes as individualism increases. Therefore, we should not be surprised when we see increasing nonconformity and fewer constraints. In The Rules of Sociological Method, Durkheim described how people should do sociology. He said social scientists must study social facts in the same way natural scientists study natural facts.
