An ongoing debate, in sociology, consists in determining whether society is a product of the individual or, rather, the latter a product of the former, a debate which is extended through the opposition between synchrony and diachrony. Social network analysis marks a step toward the reconciliation of these two positions, but this advance is minimal: much like Complex Systems Theory as elaborated through the RNSC (Réseau national des systèmes complexes), it allows for the coexistence of structural and individual analysis, but isolates one from the other, on the analytical level, individual and system and does not take into account the historical aspect of sociality. This paper explores the possibility of constructing a model which poses the inseparability of the three categories that are individual, system and event. It starts by attempting to establish that the sociological tradition, to this day, has explored and associated these categories through its different theoretical streams, each of which can be inserted into a category-association-based grid. It then draws attention to the sterile nature of the recurring controversy regarding the incompleteness of these associations or combinations and poses, as a way around these disputes, the above-mentionned relational model. This trialectical, macro-level model treats the three categories — individual, system, event — as intertwined, one never having precedence over the other and each possessing the analytical status, whether alternately or simultaneously, of cause and effect, thus allowing them to circulate in a Möbius-loop-like fashion.
