A discussion of temporality in structure.

This will be a theoretical review of the literature on (genetic) (evolutionary) structuralism proceeding from Saussure and Benveniste (on syntagms) and Lévi-Strauss (on marriage exchange) to conversational analysis (on adjacency pairs and canonical sequences such “the joke” or “the learning lesson”) of shorter and longer sequences involving more and more people.

This develops a presentation I started in 2002 to explain the potentialities of the notion of syntagm in conversational analysis.
