Philosophy is a theoretical and systematic world outlook, a generalization and summary of knowledge of nature, social knowledge and thinking knowledge, and a unity of world outlook and methodology. Compared with specific science, philosophy reveals the laws of a specific field of nature, society and thinking, while philosophy abstracts the most universal essence and laws by summarizing and sublimating individual laws and characteristics. It can be seen that philosophy has guiding significance to many natural sciences, including medicine. For many years, many scholars have regarded Chinese medicine as a philosophy, which I think is debatable. 1 Medicine is not equal to philosophy. It is generally believed that medicine is a science that deals with "problems related to human physiology in a good state" in the definition of human health, with the aim of treating and preventing physiological diseases and improving human physiological health. In a narrow sense, "medicine" only treats diseases and promotes the recovery of effective functions of the body. "Medicine" in a broad sense also includes China's health preserving theory, western nutrition, psychological, social and behavioral intervention and other related theories and practices. From this point of view, medicine is first and foremost a technology, a technology to save lives and protect health, which should be said to belong to the category of natural science. Philosophy is a variety of ideologies planned by human consciousness through objective logical thinking. In May 2003, Zhang Ronghuan, a contemporary anthropologist, defined philosophy as: "Philosophy is a tool of human reason. From its origin, philosophy shoulders the mission of solving problems about the nature and truth of the world, how we know or know the truth, the significance of life and moral practice, and the summary of all kinds of knowledge. " There was no clear division of disciplines in ancient times, and many works were often comprehensive. The records of China's early medical activities and medical knowledge are scattered in many different works. For example, the records of the medical system can be traced back to Zhou Li Tianguan, which records the duties of four different medical officials: food doctor, disease doctor, choice doctor and veterinarian. Another example is Aristotle, a famous western philosopher, who classified more than 500 different plants and animals, made anatomical research on more than 50 animals, pointed out that whales are viviparous, investigated the development process of chicken embryos, and wrote books closely related to medicine such as anatomy and physiology. However, just because medical knowledge is recorded in ancient philosophical works, or philosophers have mastered medical knowledge and engaged in medical research and practice at the same time, it cannot be considered that medicine and philosophy are the same concept. With the progress of human science and technology, the classification of disciplines is becoming clearer and clearer. The classification of disciplines is based on a comprehensive analysis of five aspects: research objects, research characteristics, research methods, derivative sources of disciplines, research purposes and objectives. From these five aspects, medicine and philosophy should belong to different disciplines. However, the intersection and correlation between disciplines does not mean that they are the same subject field. Some scholars put forward the concept of "medical philosophy", holding that the category of medical philosophy is the most basic and profound concept in the theoretical system of medical philosophy, a cognitive procedure for people to grasp life and health problems, and a thinking form for logically classifying medical problems. The category of medical philosophy is the unity of multiple academic relations between philosophy and medicine, the combination of abstraction and concreteness, universality and particularity, stability and variability, and embodies multiple values such as academic value, practical value and cultural value. This is the concept of medical philosophy, but it does not mean that medicine is equal to philosophy. Traditional Chinese medicine is a special "medicine-philosophy" model, which shows that in the development of traditional Chinese medicine, its theoretical construction is inextricably linked with China's ancient philosophy, so that some scholars think that traditional Chinese medicine is simple materialism and dialectics. Although there was a tradition of "Yi" and "Yi" theory in ancient China, in medical and Yi-ology works, "Yi" was mainly used to explain "medicine", and "Yi" was the reasoning tool of "medicine" rather than the medicine itself, so it is worthy of in-depth analysis to regard philosophical speculation as a medical theory. The above shows that philosophy is not equal to medicine, and medicine cannot be separated from philosophy. Medical philosophy and TCM theory contain rich philosophical thoughts, which is a microcosm of philosophical mission. There are philosophical thoughts in medicine. Although medicine is not equal to philosophy, it does not mean that the two are unrelated. Philosophy plays a guiding role in the development and practice of medicine. Medical theory and practice, especially Chinese medicine, contain rich philosophical thoughts and methods. For example, the basic framework of TCM theory was basically formed in the pre-Qin and Han dynasties, and Huangdi Neijing was the foundation stone of TCM theory. In the process of constructing the theory of TCM, influenced by the philosophical thoughts of the same period, TCM absorbed many philosophical theories, such as the theory of Yin and Yang, the theory of Five Elements, and the theory of essence and qi, and combined them with the observation and analysis of human physiological and pathological phenomena, which became an important thinking mode tool in the process of constructing the theoretical framework of TCM. For example, the theory of Yin and Yang has been adopted in all chapters of Huangdi Neijing and has become an important part of TCM theory. Su Wen's theory of Yin and Yang should be likened, and put forward that "Yin and Yang are the way of heaven and earth, the discipline of all things, the change of parents, the source of life and death, and the house of gods", "Look at the color and pulse, let alone Yin and Yang", and "Yang disease cures Yin, Yin disease cures Yang" is another example in Su Wen's Four Qi Tunes God: "The man of Yin and Yang in four seasons is the foundation of all things." "Angry God" said: "Don't keep secrets, don't talk. Yin Pingyang is the secret, and qi is the rule. Yin and Yang are separated and refined. " "Ling Shu Lun Disease Diagnosis Ruler" said: "The change of the four seasons, the victory of cold and summer, the heavy yin will be yang, and the double ninth festival will be yin. Therefore, yin dominates cold and yang dominates heat. So, cold is hot, and hot is cold. Therefore, cold produces heat, and heat produces cold. This change of yin and yang is also. " And so on, it can be seen that the theory of yin and yang involves many fields such as basic theory, diagnosis, treatment, health preservation, disease prevention and so on. For another example, after the pre-Qin and Han Dynasties, during the Song, Jin and Yuan Dynasties, the combination of philosophy and traditional Chinese medicine reached the second peak, and a large number of medical works used philosophical views to explain medical principles. As the Summary of the General Contents of Sikuquanshu said, "The gateway of Confucianism was in the Song Dynasty, and the gateway of medicine was in the Jin and Yuan Dynasties". Neo-Confucianism in Song Dynasty, based on Confucianism, introduced Taoism and interpreted Confucian classics, which had a profound influence on the medical family of the same period or later generations, whether it was its academic style or some specific philosophical thoughts and methods. To put it simply, it can be seen from the names of medical works such as The Scholars and Ge Zhi Yu Lun. During this period, western medicine gradually changed from the traditional "biomedical model" to "bio-psychological-social medical model". The change of this model has added many unnatural scientific elements to the original medical model. But this change is precisely to understand the problem as a whole, and it is also the embodiment of philosophical thought. Materialist dialectics holds that the world is material and matter is interrelated. Many major breakthroughs in the development of medicine shine with philosophical wisdom. Although it cannot be said that medicine is equal to medicine, the rich philosophical thoughts contained in medicine guide the formation, growth and development of medicine. Chinese medicine scholars should pay special attention to the philosophy that Chinese and western medicine have roughly the same origin. It mainly includes: ① the instinctive behavior of rescuing and begging for food. ② Life experience makes medicine. (3) The combination and division of doctors and wizards. ④ The peak of Chinese and Western medicine in the axial age. Jaspers once said: "If history has an axis, then we must regard this axis as a series of events of significance to all mankind …" This stage is an important period for the development of philosophy, science and culture in the East and the West. In China, a hundred schools of thought contend, while in the west, phidias, Archimedes and Socrates appeared. Huangdi Neijing and Hippocrates Complete Works respectively represent the foundation works of Chinese and Western medical systems, and were also born in this era. However, with the changes of the times, the two kinds of medicine have embarked on different development paths. On the basis of anatomy, physiology and other natural sciences, western medicine pays attention to experiments, and, like natural sciences, becomes an independent discipline alongside philosophy. Chinese medicine never abandoned ancient philosophy for a moment. In the development of thousands of years, it has continuously applied these philosophical thoughts to medical practice and accumulated rich clinical experience. Today, western medicine has begun to advocate "biological-psychological-social medical model", which shows that after thousands of years of development, they will return to the source of philosophy to find wisdom. Traditional Chinese medicine is like a rich treasure house, which contains the wisdom of our ancestors for thousands of years, and the key to this treasure house is China's ancient philosophy. Whether it is Huangdi Neijing, Treatise on Febrile Diseases, or later doctors, they all use philosophical thinking as a tool to inherit the academic essence from generation to generation. For example, Su Wen's theory of the formation of five zang-organs puts forward that "the images of five zang-organs can be analogized", while Shangshu Hongfan holds that "the five elements ... water is moist, fire is inflamed, wood is straight, gold is leather, and soil is fat", and treats things according to the theory of five elements. Another example is Zhang's drug classification method of "wind rising, heat floating, wet formation, dryness decreasing and cold storage", which is also the concrete application of the five-element theory of "analogy with images". It can be seen that the theoretical framework and clinical practice of traditional Chinese medicine contain philosophical wisdom. Therefore, as a scholar of traditional Chinese medicine, to learn, understand and master China's ancient medical classics, to better inherit and carry forward the academic thoughts and experiences of predecessors, and to truly inherit and innovate, it is inseparable from the tool of philosophy.
