永嘉学视野中的理体学与心体学——项乔的理气心性论

项乔体会“四书五经”之言，就是体悟圣贤的心学，进而融通义理。他认为，阳明发朱熹之所未发，“致良知”是其独创之见。良知作为天理而主于虚，虚能容物，推致良知于事物。虚实一源，显微无间。项乔的“致良知”“求放心”之学，是在圆融孟子、《中庸》和阳明心体学，并融通朱熹的观点而阐发自己的独创见解，进而探索理气和道器的关系。项乔融突和合程朱理体学与陆王心体学旨在归本圣贤经典的理想人格，高扬随事在物即行的德性，终成心体学的事功学。

School of Principle and School of Mind in the View of Yongjia Utilitarian School——Xiang Qiao's Theory of Li-Qi and Xin-Xing

Xiang Qiao's comprehension of the “Four Books and Five Classics” means to understand the sprint of sage, and then integrate the meaning.In his opinion, “Extension of Intuitive Knowledge” was Yang Ming’s original idea. As the principle of heaven, conscienceis based on emptiness, which can hold and extend into things. Vacuity and reality share the same origin, and the apparent and the subtle are inseparable.Xiang Qiao's “seeking conscience” and “seeking the lost mind” elucidated his own original ideas by integrating Mencius's “Doctrine of the Mean”, Yang Ming's “School of Mind ”, and Zhu Xi's views.Then he explored the relationship between Li-Qi and Tao-Qi.He integrated Lu Wang's School of Mind with Cheng Zhu's School of Principle, aiming at returning to the ideal personality of sages and classics, promoting the virtue of doing as things go, and finally forming the Utilitarian School.
