Final answer:
Durkheim's concept of social cohesion in growing societies is termed organic solidarity, which arises from the interdependence created by specialized labor.
Step-by-step explanation:
According to Durkheim, as a society increases in size, its division of labor becomes more specialized, and people become increasingly interdependent. This form of social cohesion is termed organic solidarity. Durkheim saw organic solidarity as key to the functioning of modern, complex societies where individuals perform different tasks and have different values but are bound together due to interdependence created by this specialized division of labor.
Organic solidarity is contrasted with mechanical solidarity, which prevails in preindustrial societies where shared beliefs and similarities connect individuals. Although the shift to organic solidarity leads to greater individualism and division of labor, it is instrumental in maintaining the cohesion and operation of advanced societies.
