Abstract
This study focuses on discussing several issues that we encounter when we 'modernize' the fundamental theories of Korean Medicine(KM): It is pertinent to set the boundaries of the "fundamental theories" of the KM. The boundaries can be set based on: a) setting the medicine and the philosophy of medicine apart and b) re-evaluating the traditional theories of KM based on the needs of the modern practitioners of KM. The fundamental theories of KM should focus on how effectively they can observe, explain, and predict the clinical cases. The clinical cases and observations should not be distorted in order to satisfy the theory. "The modernization of KM" can be defined as the change in traditional medicine to fit the needs of the contemporary world, while not losing the focus and the nature of the KM. The fundamental theories of KM will play a key role in modernizing the KM, as the focus and the inherent nature of the KM comes from these fundamental theories. The modernization of the fundamental theories of KM will be crucial to both possible models of future healthcare system-the plural healthcare system, or the western medicine-centric integrated healthcare system. The modernization will also help in advancing the future medical studies. The key to modernization of the fundamental theories of the KM is in translating the key terms of KM in modern light. As a solution, this study suggests paying attention to the 'scientific metaphors', and especially to the 'theory-constitute metaphors' among those. More in-depth studies need to be done on these.
