(b) Theoretical Study and Medical Science
Theoretical study will be able to play a significant role in medical science, because it allows medical researchers to deduce how obscure mechanisms occur in a human body. Medical researchers, as explained on the previous page, usually choose laboratory study to examine accurate microscopic mechanisms in a human body. However, even if they check various microscopic mechanisms by using laboratory study, they will be unable to grasp how a human body controls the function. This is because a human body maintains the life on the basis both of the microscopic and the macroscopic function, and which have different roles in controlling a human body. In order to deduce what macroscopic mechanism controls a human body, medical researchers should make a good use of theoretical study.
Importantly, theoretical study enables us to deduce clearly how an organ causes disease. "As if any system in nature maintains its structure by the stability, a human body also maintains its structure (the life) by the stability." This fact leads us to indicate how a human body causes disease. Specifically, a human body is a relative system consisting of organs, each of which balances itself with the background organs. This balance works as the stability of a human body, and which permits a human body to maintain the life. Thus, when an organ in a human body loses the best balance with the background organs, it tries to regain the best balance. Through this process, an organ can theoretically be considered to cause disease.
Furthermore, this indication will also lead us to notice that a human body can change the microscopic function to repair the macroscopic one. Although the majority of medical researchers unconsciously believe that the fundamental cause of disease originates only in microscopic mechanisms in a human body, they have to recheck such a belief to find out the fundamental cause of disease. Specifically, before focusing on checking a gene, medical researchers should consider whether a human body requires the organ to change the arrangement of a gene. For this purpose, all the medical researchers, before examining a phenomenon, should consider logically why a human body causes disease.
All in all, theoretical study must be essential for medical researchers to analyze disease, because it teaches them where and how to check obscure phenomena observed in a human body with disease. Laboratory study, as explained before, certainly enables medical researchers to examine accurately microscopic mechanisms in a human body. However, different from theoretical study, laboratory studies do not allow medical researchers to find out by what mechanism a human body controls the microscopic mechanism. In order to find it out, medical researchers need to begin by connecting these microscopic mechanisms with a logical line; after that, by using the indications, they should check the mechanisms by laboratory study. Only this procedure must allow medical researchers to analyze disease effectively. That is, theoretical study as well as laboratory study are essential for medical researchers to find out the true mechanisms in a human body, and for medical science to make a great progress.
