Objectives : We analyzed the descriptions of Doek(德)·Qi(氣)·Saeng(生)·Jeong(精)·Sin(神)·Hon(魂)·Baek(魄)·Sim(心)·Ui(意)·Ji(志)·Sa(思)·Ji(智)·Ryeo(慮)․Ji(智) which are the concepts mentioned in the beginning of the ≪Lingshu·Benshen≫. Methods : We reinterpreted this verse in ≪Lingshu·Benshen≫ from the viewpoint of evolution and development of mental function and considered it in relation to the knowledge of modern psychology and brain science. Results & Conclusions : The reproductive essence of the parents are combined, primitive essence(元精) is created and simultaneously primitive spirit is born. Primitive spirit first differentiates into Hon and Baek. Hon and Baek are instinctive mental functions. Up to this point, because the process is completed before birth, primitive spirit, Hon, and Baek are innate spirit. Ui, Ji, Sa, Ryeo and Ji are the rational thinking abilities as mental functions that develop actively after birth. This is called conscious spirit and acquired spirit. Analyzing the contents of <Benshen>, it can be said that the mental function is divided into four layers of primitive spirit-Baek-Hon-conscious spirit.
