本体是哲学的核心范畴,确立本体观念曾是哲学的最高目标。“道”是庄子哲学所确立起来的本体观念,具有本体与境界两层含义。“道”之意义的二重性不仅反映了哲学的超越意识与寻根意识、明证性要求与确定性要求的内在统一,而且引发了哲学内部诸多的理论效应。 Ontology is the core category of philosophy. Establishing the concept of noumenon was the highest goal of philosophy. Tao is an ontological idea established by Zhuang Zi philosophy, which has the two meanings of ontology and realm. The duality of “Tao” not only reflects the inherent unification of philosophical transcendence and root-seeking, demonstrative and deterministic requirements, but also triggers many theoretical effects within philosophy.
