Sociology of social changes

This article defends the hypothesis according to which there takes place a diversification and multiplication of the social change that is defined as a circular phenomenon in which the actors produce systemic transformations that in turn, face the individual behaviours. If the notion of social change is innate to the sociology because this discipline is constituted in reaction to the events that have transformed the social order during the XIXth century, it has turned progressively into an essential part of the contemporary sociology along with the action and social organization. As consequence of the social, economic and cultural mutations of last thirty years, it is convenient restart the reflection about the social change, which implies to study the theories, the level of analysis, the tendencies and the explanations of the social change.
