Interlocutory logic

After exhibiting the historical and epistemic context of the discovery of the interaction order, the authors develop a global theory of the cognitive-affective-social organization of talk-in-interaction: «Interlocutory Logic». On the basis of insights provided by the pragmatics of natural languages and the theory and methods of contemporary logic, this theory deals with elementary illocutionary acts and higher-order units (turns, exchanges) of conversation with the help of methods of natural deduction and dialogical logic. The authors present a model constructed within the empirical domain of functional dialogues during «hand-overs» between work-shifts in a factory to demonstrate the descriptive and explicative values of «Interlocutory Logic».
