인문학과 신경과학의 통합적 고찰을 통한 언어의 복잡계적 진화

Abstract

This study examines the birth and evolution of language from the perspectives of philosophy in the Age of Enlightenment, modern linguistics, and neuroscience. Focusing on Rousseau's view and combining the perspectives of 18th-century philosophy and modern linguistics, one can presume that human language has evolved into a complex system through three stages: The first stage is the emergence of "sensory-based gesture language" shared by all animals with sense. The second is “emotion-based early voice language”, associated with the nature of mammals going through conception and lactation. Finally, the third is the inception of “reason-based late voice language” by logical operation and information processing. From the perspective of neuroscience, the origins of the three types of languages are related to the basal ganglia and cerebellum involved in sensory movements, the limbic system involved in emotion and memory, and the cerebral cortex, respectively.
