The Analysis of Socio-cultural Dynamics in Ethnographic Context Demonstrates with Archaeological Witnesses, in Central Africa and the Middle East, the Gap Between Form and Function

The morpho-functional categorization of material objects used in archaeology reflects a determinism. Form determines the function of a material object. The function is systematically deduced from the form even before the former manifests itself. However, the usefulness of an object can clearly override this prognosis. The problem, then, is to verify the pre-established relationship between a predetermined activity and a predefined set of morphological characteristics required to give a material object or an archaeological assemblage its name. The latter two are defined on the basis of a set of stable characteristics. The question is how to proceed in order to highlight the dynamic nature of the object or archaeological assemblage beyond the stable state of the combination of elements by which an ethnographic object or archaeological assemblage is identified? And how can we ascertain whether the set of morphological characteristics identified with an object, or the group of remains required to form an assemblage, can be explained systematically by a static need for overproduction that is generally attributed to human societies, regardless of context. The hypothesis asserts that the utility of the material object transcends morpho-functional limits. Just as the different states of descriptive variables in archaeological assemblages are not necessarily the consequence of a uniform and continuous need for overproduction. The aim of this study is therefore to discuss the relationship established between socio-cultural dynamics and the properties of the causes generally given as stable in the explanation of this phenomenon. The results drawn from an analysis of qualitative data, collected in the written literature and in the field, will serve as a basis for discussing the conceptual model established in the explanation of observable dynamics, concerning the material productions of human societies. The functionalism-nominalism-interactionism triad serves as the basis for the theory proposed to render intelligible the precarious quality of the causes at the origin of the transformations recorded in material objects in ethnographic or archaeological contexts.
