This paper is aimed at finding out the clue to the medical solution to the pathological phenomena of the dehumanizing and demoralizing state of our society by centering around the Chiljeong that originates from Oriental Medicine, Sung Confucianism and Sa-sang Medicine(四象醫學). In these fields,the Chiljeong is based on the theory of Eum-yang and Viscera(陰陽.臟腑論) in Oriental Medicine, on the problems of good and evil in Sung Cunfucianism and on the theory of Sa-sang Visceral Localization(四象.臟局의 理論) in Sa-sang Medicine. The principles of geneation of Chiljeong : In case of Oriental Medicine, Sin(神) controls Chiljeong and of it is stored in five Viscera, it becomes Sin in the Heart, Hon(魂) in the Liver, Sa(思) in the Spleen, Bed-Woo(悲.憂) in the Lung, and Kyeong-Kong(驚.恐) in the Kidney. Then five Viscera react with outer stimuli or Sin, it gives off Chiljeong as Joy(from the Heart), Anger(from the Liver). Thought (from the Spleen), Anxiety and Sorrow(from the Lung) and Surprise and Fear(from the Kidney) In Sung Confucianism, Sim(心) comtrols Seong-jeong(性.情), and at the moment of that Sim gives off Jeong(情), it becomes good when the Li(理) gibes off itself and then Chi(氣) follows Li, or Chi gives off itself and is regulated optimally, out it becomes evil when Li cannot preside over Chi and then shaded by cloudy Chi. The pathology: If the Chiljeong exceeds one's capacity, the corresponding Vicsera will be damaged, and the Passions(喜.怒.哀.樂) that may harm to four types of constitution severly are the Joy and Pleasure(in Tae-eum-in 太陰人 and So-eum-in 少陰人) and Grief and Anger(in Tae-yang-in 太陽人 and So-yang-in 少陽人), so one should be alert on some passions by regrding his constitutional frailty. More over, because of the variations in Sa-sang Visceral Localyzatin there is various ability in human affairs, but as the clumsiness in human affairs may make him hurt by it, so one should be prevented from these passions and human affairs, that is flowing Joy and Participations(黨與) in Tae-yang-in, flowing Pleasure and Dwelings(居處) in So-yang-in, explosive Anger and Companies(交遇) in So-eum-in, explosive Grief and Affairs(事務) in Tae-eum-in. How to clutivate the human nature: The ulitmate purpose in Oriental Medicine is preserving Cheon-Jin(天眞), that is following the Tao(道) by making him be in harmony with the Chi(氣) of the Seasons and by living a simple life. In Sung Confucianism, the way preventing the lustful desire and preserving Cheon-li(天理) is to observate derectly the calm, original place of human nature with reverence, when Sim has nat given off itself yet, and when Sim has already given off, it also is to meditating on one's passion and thought that the principle of good should be researched on or the evil should be cut off according to it's being good or evil. Such like as these various aspects of research on the Chiljeong it will be helpful in understanding human nature by producing the various materials on it, moreover, by doing so, we can lead out appropriate solution on the confusions of judgement value and demoralization.
