의학은 물질인 인체의 이상증상을 다루는 학문이기 때문에 당연히 과학에 근거하여 성립된 학문이라고 생각한다. 그러나 사상의학은 인체의 생리(生理)가 인간본래성인 성정(性情)에 근원하여 작용하며, 갖가지 육체적 병들도 잘못된 성정의 작용에 의한 기(氣) 흐름의 異常에 의하여 비롯됨을 강조한다. 즉 의학은 육체의 병을 치료하는 학문이지만, 병이 생기는 것은 잘못된 기 흐름 때문이며, 기 흐름을 주관하는 것은 성정이기에 병을 치료하기 위해서는 형이상적 존재인 성정이 어떤 존재이며, 어떻게 작용하는지를 알아야 한다는 것이다.
본 논문은 형이상적 존재인 성정과 그 작용성 및 사상의학의 생리작용이 역학의 형이상적 존재원리에 근원을 두고 있음을 탐구한 것이다. 즉 역학의 음양오행론에 근거하여 ‘성정의 존재구조와 작용성’ 그리고 ‘타고나는 성정의 차이에 의한 장부의 크고 작음과 사상체질’ ‘인체에서의 기 흐름’ 등에 관하여 고찰한 것이다.
Since medical science deals with the abnormal symptoms of a physical organism, the study is considered to have been formed naturally on the basis of science. However, Sasang Constitutional medicine emphasizes that the physiology of an organism functions grounded on a nature and feeling, human nature, and thus different physical illnesses originate in disorder of the flow of internal energy by the defective function of a nature and feeling. In other words, medical science is the study treating diseases and a disease originates in the wrong flow of internal energy, which is controlled by a nature and feeling. Therefore, in order to cure a disease, it should be understood what a nature and feeling is, which is the metaphysical being, and how it functions. This paper aims to research a nature and feeling, which is the metaphysical being, its principle of action and the physiology of Sasang Constitutional medicine structured by the metaphysical principle of existence in the learning of Zhouyi. That is to say, this research includes ‘the structure of being of a nature and feeling and its principle of action’, ‘large and small size of internal organs and Sasang constitution depending on the difference of inborn nature and feeling’, ‘the flow of internal energy in the organism’ and so on, based on the interacting principles of Yin and Yang and the Five Elements in the learning of Zhouyi.
