知性作为认识辩证发展的一个环节、独立阶段，在 80年代初中期曾引起国内学者的广泛讨论，但终未成定论。笔者试从哲学史的视界，考察了由柏拉图至康德、黑格尔到马克思、恩格斯、列宁的知性思想，目的就在： (1)论证知性的客观存在； (2)凸现知性本身的理论、由来、发展及其意义，从而使我们对于知性有个较为完备的了解。 　 As an aspect of understanding dialectical development, intellectual independence caused widespread discussion among domestic scholars in the mid-1980s, but it was not a final conclusion. The author tries to explore the intellectual thought from Plato to Kant and Hegel to Marx and Engels and Lenin from the perspective of the history of philosophy. The purpose is: (1) to demonstrate the objective existence of intellectuality; (2) to highlight the theory of the intellectual nature, Origin, development and its significance, so that we have a more complete understanding of intellectual.
