The perceptual-cognitive foundation of some basic grammatical structures and propositional logic

AbstractThis article describes a theoretical attempt to found basic grammatical structures on a framework of the human perceptual-cognitive system (PCS). The basis of this study is the idea that perception and cognition of things in the world (objects, properties, events, facts, etc.) would be creation of a kind of models of the things that embody pieces of information about the things. This idea suggests that such models should have structures that correspond to grammatical structures of the linguistic expressions that express the pieces of information embodied by the models. The model structures that correspond to the grammatical structures and logical connectives have been derived within the scope of the computational theory of PCS, from the way in which PCS should function to form the models. It can be shown that propositional logic is derived from the structures.
