Social static focuses on how order is maintained in the society and social dynamic focuses on how society changes over time.
Comte separated social statics from social dynamics. Social statics are concerned with the ways in which the parts of a social system (social structures) interact with one another, as well as the functional relationships between the parts and to the social system as a whole. Comte therefore focused his social statics on the individual, as well as such collective phenomena as the family, religion, language, and the division of labor.
Comte placed greater emphasis on the study of social dynamics, or social change. His theory of social dynamics is founded on the law of the three stages; i.e., the evolution of society is based on the evolution of mind through the theological, metaphysical, and positivist stages. He saw social dynamics as a process of progressive evolution in which people become cumulatively more intelligent and in which altruism eventually triumphs over egoism. This process is one that people can modify or accelerate, but in the end the laws of progressive development dictate the development of society. Comte's research on social evolution focused on Western Europe, which he viewed as the most highly developed part of the world during his times.
