Wang Fu-Zhi was a knowledgeable man, whose scholarship related to philosophy, history, literature, politics, natural science, and so on, among which the most influential subject was the doctrine of Tao. The doctrine of Tao was one of the issues that scholars of Li focused their attention on. To doctrine of Tao was one of the issues that scholars of Li focused their attention on. To underscore that Tao was an ultimate being, the Neo-Confucians recurrently advocated that Tao was a transcendental and metaphysical noumenon. Tao, Tai Chi, the cosmic principle and human nature, all of these originated from real life, but the Neo-Confucians’ claim transformed them into abstraction and mysticism. In Ming Dynasty, there emerged a philosophy that not only took “mind” as the center of the universe but also considered the “way of heaven and earth” to be the ordinance of “mind.” All these points mystified Tao even further, whereas nonsense conversations and behaviors prevailed in Ming Dynasty and led to the fall of the country. After the fall of Ming Dynasty, Wang Fu-zhi devoted himself to writing and drew historical lessons from the fall of the country. He reflected on every aspect of thought and culture, which were built around the doctrine of Tao. He argued that the way to learn the lessons and right the wrong was to resolve the problem of Tao. The intellectual Achilles’ heel in Sung and Ming Dynasties was the nonsense conversations and behaviors, and his mission was to direct the insubstantial and metaphysical Tao back to the real and physical world. Therefore, the aim of his exploration of Tao was to substantialize the abstract Tao.
