论思的合理性

On Rationality of Thinking

西方哲学实践理性与认知理性的关系问题，也就是中国哲学求道与求学的关系问题。本文所表达的思想，在理解层面上就是实践理性与认知理性或求道与求学关系的学理；在存在层面上就是与事物本性同一的道或存在和与事物的本质同一的理或在者关系的学理；在知识层面上就是价值与事实关系的学理。认知理性内在于实践理性，求学内在于求道，或者说认知理性是实践理性的一个环节，求学是求道的一个环节。道或存在是事物生命的主宰，理或在者是事物作为生命的秩序或外在形态。绝对价值作为客观性就是事实问题，同时事物存在的意义或价值决定事物的类本质及事物之间关系的理这一事实。

The identical problem about practice reason and understanding reason in western philosophy is one about seeking Tao and seeking Xue in Chinese philosophy. The thought expressed in the thesis is a Xue-Li about the relation between practice reason and understanding reason or seeking Tao and seeking Xue on the understanding layer. It is a Xue-Li about Tao or existence of identity with the nature of thing and Li or allthings of identity with the essense of thing on the existence layer. It is a Xue-Li about the relation between value and fact on the knowledge layer. Understanding reason is contained in practice reason, and seeking Xue is contained in seeking Tao, namely understanding reason is a link of practice reason and seeking Xue is one of seeking Tao. Tao or existence is the dominator of thing as life. Li or all-thing is the order or external form of thing as life. Absolute value as objectivity is a problem of fact, meanwhile the meaning or value of existence of thing determines the fact of categorical essence of thing as well as the relation as Li among things.
