Etic and behavioral infrastructure, comprising a society's relations to the environment, which includes their ethics and behavioral modes of production and reproduction (material relations). • Etic and behavioral
Structure, the ethics and behavioral domestic and political economies of a society (social relations). • Etic and behavioral
Superstructure, the ethics and behavioral symbolic and ideational aspects of a society, e.g. the arts, rituals, sports and games, and science (symbolic and ideational relations). • Emic and mental Superstructure, including "conscious and unconscious cognitive goals, categories, rules, plans, values, philosophies, and beliefs" (meaningful or ideological relations). Within this division of culture, cultural materialism argues for what is referred to as the principle of probabilistic infrastructural
determinism. The essence of its materialist approach is that the infrastructure is in almost all circumstances the most significant force behind the evolution of a culture. Structure and superstructure are not considered "insignificant, epiphenomenal reflexes of infrastructural forces". The structure and symbolic/ideational aspects act as regulating mechanisms within the system as a whole. == Research ==
