This paper investigates the theory of conflicts in G. Zimmels philosophy where the phenomenon of a contradictory interaction is considered as a condition of development. The social conflicts typology is presented (i.e., economic, political, cultural, spiritual, etc.); the process of conflict emergence and connections of those conflicts are explained. Social contradictions are proved to be continuous and stimulate dramatic changes in all the fields of life. The paper indicates that, to a large extent, every choice a person makes is driven by constraints and opportunities, generated by conflicts.
