Praxis, symbol and language
Developmental, ecological and linguistic issues
This article focuses on the interweaving of constructive praxis with communication in ontogenesis, in phylogenesis and in biocultural niche evolution (ecogenesis), within an EvoDevoSocio framework. I begin by discussing the nature of symbolization, its evolution from communicative signaling and its elaboration into semantic systems. I distinguish between the symbol-ready and the language-ready brain, leading to a discussion of linguistic conceptualization and its dual grounding in organism and language system. There follows an outline account of the interpenetration in the human biocultural niche-complex of semiosphere and technosphere, mediated by the evolution of the niche of infancy. Symbolization (the foundation of the semiosphere) is by definition normative; the normative character of the technosphere is demonstrated by the interrelations in human development between affordance, action schema and canonical functional object schema. A model of the neuro-computational implementation of dual grounding is proposed.
