The Perceptual-cognitive Foundation of the Subject-predicate Structure

This article describes a theoretical attempt to found thesubject-predicate structure of declarative sentences on a frameworkof the human perceptual-cognitive system. The basis of this studyis the idea that perception and cognition of events in the worldwould form mental representations in the system , a kind of modelsof the events that embody pieces of information about the events.This idea suggests that such models have structures that correspondto grammatical structures of the linguistic expressions thatrepresent the events and express the pieces of informationembodied by the models. The model structures that correspond tothe subject-predicate structure and logical connectives have beenconstructed within the scope of the computational theory of the system following the way in which the system should functionto form the models of the events. This construction of thestructures entails propositional logic. Application of the structurest o the liar paradox le ads t o a new solution of this paradox .
