Human agency and social structure: From the evolutionary perspective

This article addresses the agency-structure issue from the evolutionary perspective. Rather than treating it as something unique to human society, the article examines this issue in the broad context of how different species of social organisms, with humans being one of them, influence the constitution of their societies. The main finding of this analysis is that social organisms of different species all exert influence on their societal formations, but the impact varies depending on the level of agency the organisms possess, particularly their perceptual capabilities. Social organisms with higher perceptual ability play a bigger part in shaping the structure of their societies. A fundamental difference between humans and nonhuman social animals in the agency-structure relations lies in the fact that humans are the only species on earth known to be capable of constructing institutional rules for societal regulation. This capacity is attributable to the syntactic language and reflective self-awareness humans possess. Within human species, however, there is considerable variation in the exercise of this capacity among individuals, groups, and societies. It is therefore important to examine species and intra-species level differences in addressing the agency-structure issue in human society.
