Abstract
Objective : This paper introduces a unique meridian theory developed by Japanese philosopher Yuasa Yasuo. Method : His meridian theory is well organized in his philosophy, so we systematically review his major works and philosophy from which we systematize his meridian theory. And we critically examine it with current studies. Results and Conclusions : He tried to overcome Cartesian mind-body dualism by Eastern thought and newly developing neurophysiology. He articulated "body scheme" from human information systems, primarily nervous system and meridian system, which regulate physiological functions. It consists of 1st external sensory motor circuit, 2nd circuit of coenesthesis, 3rd emotion-instinct circuit and 4th circuit of unconscious quasi-body. Meridian system is the 4th circuit, through which he thought various affect(emotion) flows. Based on the relationship of emotion-autonomic nervous system- meridian-skin, he tried to confirm the existence of meridian system. His theory illuminates mind-body problem and emotion-meridian relationship in traditional East Asian medicine.
