Between situation and evidence: the performative node Elements for a study of the conditions of the effectiveness of acts of language

Repositioning speech, whether it is rhetorical speech or performative utterance, in its context, its space and its dynamics help us determine its scope and limitations and identify related elements. Through the prism of American interactionism or French anthropology, the study of the effectiveness of "speech acts" in their actuality (and not as pure linguistic category) brings out two major elements. Firstly, the necessity of speech to inscribe itself (in dual mode) in a situation or milieu, and secondly, the importance of proof in establishing and maintaining the efficiency of the language. Complementing speech, the physical dimension must also be fairly reconsidered, because it plays a key role in the system, by overcoming the "impotences" of speech.
