关于人的认识发展阶段有所谓两分法和三分法的中西差异。导致这一差异的关键在于知性和理性有没有区分以及要不要区分。在中国人的理性概念中向来没有知性和理性的进一步区分。区分知性和理性是德国古典哲学的重大成就。这种区分对于马克思主义哲学的中国化同样具有重大意义。 There are so-called dichotomous and trichotomous differences between China and the West about the stage of human cognition and development. The key to this difference lies in the distinction between intellectual and rational and whether or not to distinguish. In the Chinese concept of rationality there has never been a further distinction between intellectuality and rationality. Distinguishing intellectual and rational is a major achievement of German classical philosophy. This distinction is also of great significance to the sinicization of Marxist philosophy.
