Zhang Zai took the lead in deconstructing the integrated pattern of Confucianism,Buddhism,and Taoism.While bidding farewell to the religious era,this change also promotes the historical progress of Chinese philosophy and opens a new chapter in Neo-Confucianism in the Song and Ming Dynasties.In response to Buddhism from the perspective of Confucianism,he establishes the ontology of qi,which proves the uniqueness and authenticity in the world of this sidedness,reaffirms the monistic worldview,and takes the first step for the thoughts of Neo-Confucianism in the Song and Ming Dynasties.His theories of taixu or the great void as qi and the unity of heaven and man have both new ideas and limitations.The neutrality of qi in value limits Zhang Zai's horizon,which makes it difficult to provide the ontological guarantees for Confucian ethics,and eventually gives way to the ontology of natural law.
