Traditional Chinese medicine is not much of a experience fact delineation and record on human body vital movement,disease process and disease therapeutics,but a theory explanation on experience fact though making observed medical phenomenon come down to general law and principle;a dialectic-analogy logic system formed by applying logical thinking law of Chinese people to tidy up medical experience knowledge;a theory medical science formed by a concept-category system organized by a series of different decks of theory categories,which has highly self-support nature in interior of theory whole and logic consistency between propositions.

Views of "Integrated whole of heaven,earth and man","Derive the theory of the human body from natural environment" and "Xing-ming Ying-yin" combined with medical practice were origins of traditional Chinese medicine theory.On the premise of ensuring internal coordination of the whole theory in accordance with the logic of proposition,physicians kept on enriching connotation,validating hypothesis and using the theories in practice,made traditional Chinese medicine theory has scientific conformation of medical model of "environment-body and spirit",logic system of "dialectical-analogize" and subject character of "manifestation-state ".

By studying Chinese medicine with judgement standard of scientific discipline of scientific epistemology, it is found that Chinese medicine takes physiological and pathological phenomenon as well as the life state reflected by them during the process of life activities of human body as research object. The method of speculating the interior change from the exterior manifestations is adopted. The discipline has a team of professional scientists that have clear research direction, academic institution, publications, and educational facilities. Chinese medicine is different from western medicine that takes structure and tissues of human body and their functions as study object, as well as adopts anatomical and experimental methods. Chinese medicine and western medicine are two branches of medical science. So, Chinese medicine should ascertain its nature as “Phenomenon-State Medicine”, and foot “Phenomenon-State Medicine” in medical science as a discipline, set up rational faith scientifically and further develop Chinese medicine according to the intrinsic law of “Phenomenon-State Medicine”.

How did Inner Canon of Huangdi(Huangdi Nei Jing) get the numerous thinking quintessences of Dao,Fa,Ru,Mo,Ming,Yin-yang,Nong and Bing etc to establish the TCM theory system? In the middle and end stages of the Warring States Period,the Ji Town School established by government official of Qi state marshaled numerous schools of Dao,Fa,Ru,Mo,Ming,Yin-yang,Nong and Bing etc,developed face to face academic communication,a hundred schools of thought contend,brought about the naissance of Huang Lao Neodoxy,which adopted the numerous thinking quintessence.It established the integration view of "heaven,earth and human",developed the thought style of understanding human rules according to the order of nature,and influenced numerous thoughts at that time and settled as the tradition thought style of the Chinese nation.Huangdi(Huangdi Nei Jing) brought the integration view of "heaven,earth and human" into the theory framework,to draw the the thought style of understanding human rules according to the order of nature,found the academic essence of TCM.

What kind of science is TCM? How to develop TCM that consistent with its inherent rule? To solve this problem,we should establish dimension research area of TCM,set up science of "theory study of TCM",evolve dimension research of TCM.We can gather a body of scholars of TCM that not only master TCM theory but also possess knowledge structure in terms of philosophy,logic,science philosophy and science epistemology et al,formation academic society,carry out research,discussion and argument.So to make clear that what kind of science is TCM,what are its theoretical structure,essential characteristic and developing rule,which aspect of biotic phenomenon,research method and thought does it study.In that way to recognize investigative aim of TCM science,establish rationality belief of science community of TCM,so as to accelerate us to choice TCM research thought that accord with its own inherent rule,advance clinical therapeutic effect and develop foundational theory of TCM.

Observation is a necessary precondition of obtaining and constructing reliable knowledge,through which people can extract nature and low of things and lives from complex phenomenon.Therefore,widely and deeply observation is an important foundation and scienti c method category of forming TCM theoretical system.

In ancient times of China, thoughts of matter differentiation developed on basis of observation. It derived from primitive gather activities, its initial form was differentiation, then, formed into classification. As a scientific methods category, the development of thoughts of matter diffetentiation also had effect on traditional Chinese medicine. It effected and controlled that traditional Chinese medicine theory showed solicitude for sorts but not structural analysis. It directed theory of traditional Chinese medicine to obtain experience, combine knowledge and construct theory system in way of methodology.

"Absorbing image "is an important method in establishing fundamental theoretical system of TCM.The term and concept of "nomenclature according to manifestations" is the starting point of theoretical thoughts and the results of scientific studies."Testing viscera via the state of internal organs" is a method of "understanding the interior from the exterior",which makes TCM surpass productivity level and practical tools of that time,finally aquire knowledge.The huge theoretical system of TCM is constructed on the basis of "classification according to manifestation",discovering unknown fields according to infinite knowledge.

China ancients were good at the use of yunshu,they used mathematics method to study the life movement,explore the rule of disease,Those were the important scientific method and theoretical category of establishment of TCM theory system by Inner Canon of Huangdi.The yunshu thought in Inner Canon of Huangdi started from metric and developed to calculation,it contained the mathematical thought of shu and xing,and the trace of taking shu as image.

The basic concept and category of"consciousness"from Inner Canon of Huangdi put forward to understanding the life motion and laws through analysis and inference in order to construct TCM theoretical system,which proposed the question of theory thoughts.There are two explanations about consciousness:1.Theory thoughts in method of experience and cognition,which means during the activity of observing and recognizing,organizing perceptual cognition with theoretical knowledge of ying-yang,five phases and so on to achieve purpose of identification;2.Explaining experiential facts with certain theories and creating some theoretical hypothesis,in order to achieve the purpose of rising experiential knowledge to theoretical knowledge.
