First, Mechanical Solidarity which includes the common roots of identity and similarity across a social group, the solidarity is derived from likeliness and obligations. Second, Organic Solidarity is the mutual dependency based on interdependence of the different parts of the society. He gave the idea that societies had evolved through the division of labour from mechanical to organic forms which can also be classified as simple to complex forms.
Durkheim believed that the diminishing solidarity highlighted the pathological condition. He pointed out that modern societies need to search for new ideas for reinforcing the social norms and setup a shared belief system which promotes a sense of belonging and affiliation in a society. He suggested that social cohesion could be a resulting from the action of workgroups. Such occupational groups had the capability to replace the traditional normative functions such as religion, local community, and the family values. The relationships amongst such occupational groups would be economic in which they would work together to reach agreements regarding the conditions of labor and wages. In addition to the economical relations these relations would also be political. They would also function as social organizations because Durkheim thought that individuals within a society will share interests and a sense of collective identity.
A modern view about organization has been influenced a lot by Durkheim’s biological analogies and more importantly consensual view of social order. He gave a view that the society is interdependent and is a living eco system that comprises of interrelated parts that are depending on each other for survival.
