other animals, cannot be merely reduced to a stimulus-response system. The I–you polarity is another important development explored in the text. The third person acts under the conditions of possibility of this polarity between the first and second persons. Narration and description illustrate this. "I signifies "the person who is uttering the present instance of the discourse containing I." This instance is unique by definition and has validity only in its uniqueness ... I can only be identified by the instance of discourse that contains it and by that alone." You, on the other hand, is defined in this way: "by introducing the situation of "address," we obtain a symmetrical definition for you as "the individual spoken to in the present instance of discourse containing the linguistic instance of you." These definitions refer to I and you as a category of language and are related to their position in language." — from Problems in General Linguistics A pivotal concept in Benveniste's work is the distinction between the énoncé and the énonciation, which grew out of his study on pronouns. The énoncé is the statement independent of context, whereas the énonciation is the act of stating as tied to context. In essence, this distinction moved Benveniste to see language itself as a "discursive instance", i.e., fundamentally as discourse. This discourse is, in turn, the actual utilisation, the very enactment, of language. One of the founders of structuralism, Roland Barthes, attended Benveniste's seminars at École Pratique. Pierre Bourdieu was instrumental in publishing Benveniste's other major work, Vocabulaire des Institutions Indo-Européennes in his series Le Sens commun at radical publisher Les Éditions de Minuit (1969). The title is misleading: it is not a “vocabulary”, but rather a comprehensive and comparative analysis of key social behaviors and institutions across Germanic, Romance-speaking, Greco-Roman, and Indo-Iranian cultures, using the words (vocables) that denote them as points of entry. It makes use of philology, anthropology, phenomenology and sociology. A number of contemporary French philosophers (e.g., Barbara Cassin, Nicole Loraux, Philippe-Joseph Salazar, François Jullien, Marc Crépon) have often referred to Benveniste's Vocabulaire and are inspired by his methodology and the distinction he draws between meaning (signification) and what is referred to (désignation). Jacques Derrida's famous work on "hospitality, the Other, the enemy" is an explicit "gloss" on Benveniste's ground-breaking study of host/hostility/hospitality in the Vocabulary.
