Abstract
Claude Lévi-Strauss is aware of his affinity with the thrust of the Gestalt school. He suggests that he only adds the discipline of sociology or anthropology to those guided by the concept of Gestalt. The structure is made of several elements, none of which can undergo a change without effecting changes in all other elements. Yet one additional aspect has to be emphasized, that of possible prediction applied to a structure. The presence of the properties comprised in a structure makes it possible, according to him, to predict how the model will react if one or more of its elements are submitted to certain modifications.
