《正蒙》中的“四有句”是张载哲学的纲维。张载对“太虚”和“太和”的诠释借鉴了周敦颐“无极而太极”的思想。“太虚”与“太和”所共同构成的“天道”具有物化和德性的双重属性。从“四有句”来看,张载明“天道”是为了立“心性”。“太虚”中至善的“天命之性”与“太和”中偏斜的“气质之性”降化入人心后,人心具有了“性善”的潜能和“行恶”的可能。在维护儒家“性善论”的基础上,张载用“行恶”的可能性代替了“性恶”的问题,弥补了儒家心性论之不足。 The “Four Sentences” in “Being Mongolian” is the keystone of Zhang Zai’s philosophy. Zhang Zai’s interpretation of “too imaginary ” and “too peaceful ” draws on the thought of Zhou Dunyi “Promise and Taiji ”. “Tacit” and “Taihe ” constitute the “Tiandao ” with dual attributes of materialization and virtue. From “Four Sentences ” point of view, Zhang Qingming “Heaven ” is to establish “heart ”. “Too ” in the perfection of “Destiny ” and “Taihe ” in the skew “temperament of nature ” After the decline into people’s hearts, the people have a “good nature ” Potential and “evil” possible. On the basis of safeguarding Confucianism, “Nature and Goodness Theory”, Zhang Zai replaced the problem of “sexual evil” with the possibility of “doing evil”, which made up for the deficiency of Confucianism.
