許抗生同時參考咗新儒家嘅定義，佢認為道家發展史上係有劃時代嘅意義，就好似宋明理學吸收咗先秦儒家嘅思想。宋明理學提出咗以天理作為宇宙嘅根本思想，突破咗先秦儒家嘅學說；而魏晉玄學同埋黃老之學亦都有「名教即自然」、「值心而行」同埋「以無為體」嘅思想，呢樣都係突破咗先秦道家嘅學說。所以宋明理學可以稱為新儒家，調返轉魏晉玄學亦都可以稱為新道家。
Xu Kangsheng also referred to the definition of Neo-Confucianism, and he believed that the history of Taoism was of epoch-making significance, just as the Song and Ming Dynasty science absorbed the ideas of pre-Qin Confucianism. The Song and Ming Dynasty theories put forward the fundamental idea of taking heavenly principles as the universe, breaking through the pre-Qin Confucian doctrines, while the Wei and Jin metaphysics and Huang Laozhi also had the ideas of "famous teachings are nature", "acting with the heart" and "taking nothing as the body", all of which broke through the pre-Qin Taoist doctrines. Therefore, Song and Ming Dynasty science can be called neo-Confucianism, and the metaphysics of the Wei and Jin dynasties can also be called neo-Taoism.
