The awareness of Wu-gan is basically based on the perspective of genetic theory. It is primarily an exploration and description in ancient literary theories to discover the psychological origins of the being of literature and the aesthetic experience. It is believed in Wu-gan that the occurrence of creation is originally the result of the relationship of induction between subject and object. Therefore, to prove this belief, the study will firstly define 'Wu-gan' in terms of its theoretical content of aesthetics, inner structure and the positioning of its theory. Secondly, the study focuses on Wen Xin Diao Long, a masterpiece integrating all experience of literature creation before the Qi and Liang Dynasties. As for the issues of creation, it is believed that the philosopher, Liu Xie, has not only illustrated the original pattern of 'Bing-Qing, Ying-Wu, Xing-Gan, Yin-Zhi' and proposed his viewpoints of dialectics, namely 'Sui Wu Wan Zhuan, Yu Xin Pai Huai' to interpret the interaction between subject and object, but discovered the expression of 'matter' and the issue corresponding to 'emotion' in the relationship of induction. Consequently, regarding the element, structure and process of 'emotion, matter, feeling' in the activity of 'Wu-gan' along with the interactive model between mind and matter, it is likely to devote attention to a certain degree in the way of theory. Wen Xin Diao Long has not only provided interpretations marking the history of 'Wu-gan,' but established an innovative theoretical pattern concerning the types of content.
