On Mothodological Approach to Philosophical System of Sunology Abstract A Study on the Methodology of the Philosophical System of Sunology The focus of this doctoral dissertation is primarily predicated upon my attempt to explore the philosophical system of Sunology or Dr. Sun Yat-sen¡¦s works and the related mode and value of the methodology. As a consequence of this effort, this author suggests a common foundation of research and dialogue as a model for human epistemology. With this foundation in mind, the main dimensions of Sunology has been explored: (1) Regarding the philosophical system, the method of content analysis in social sciences has been applied, yielding its peculiar characteristics and mode; (2) Regarding its logical structure, the axiomatic method has been employed so as to testify that Dr. Sun¡¦s logical structure is well integrated; (3) Regarding Dr. Sun¡¦s operational dimension, the mode of interdisciplinary integration has been used, so as to clarify his operational conversion; and (4) Regarding Sunology¡¦s consistency in its logic, an attempt has been made to explore its methodology, so as to find out its form and value and, at the same time, the kind of method and approach to materialize an ideal. From the study, one should realize that mankind ought to seriously weigh the value of any given theoretical and philosophical systems in the past and fully appreciate its latent significance and validity. As a next step, one should try to put it into practice. Subsequently, an attainable framework should be constructed, so as to fulfill the projected undertaking. However, we should understand that the approach and method should not be just limited to this. At the same time, it should be noted that our framework argues that knowledge has a holistic structure which can be mutually continuous. Philosophical systems are interrelated. When analyzing any change in the relationship and its development, it is necessary to clarify the structure and operation aspects of the two. Only having done that, can we enhance the clarification and systematization of thinking. And only then, can we handle humankind and nature¡¦s mutual movement. Unless this is done, it is not possible for us to have an original look at human thinking and knowledge construction. In this connection, it should be noted that each discipline has its background and knowledge. Based on this, can we develop pervasive and automatic mode of knowledge. After that, can we have the ability to be creative. As a result, human knowledge and culture can continue its integrative process and be progressive.
