在西方哲学史上,特别是在德国古典哲学中,“知性”和“理性”是两个很重要的范畴.它们涉及到思维发展的基本过程问题.探讨“知性”和“理性”在思维过程中的地位和作用,弄清楚它们的辩证关系,这对于我们掌握理性认识的具体阶段,正确地运用辩证思维方法,有着重要现实意义. In the history of Western philosophy, especially in the German classical philosophy, “intellectual” and “rational” are two very important categories that involve the basic process of thinking development. The status and role of “reason” in the process of thinking and clarification of their dialectical relationship have important practical significance for us to grasp the concrete stages of rational understanding and to correctly apply the dialectical thinking method.
