The complexity and multilayeredness of social development are conditioned by corresponding, immanent complex systems of economic contradictions, laws, and relations. The multisystem dialectics of the complex whole and the multisystem dialectics of the heterogeneous and multilayered determine the specifics of the dialectics of social development and the scale of research problems. The laws that are found in the study lead to the problems of dialectical cycles of economic development, in which the dialectics of the contradictions themselves play an essential role.
