因果问题在康德《纯粹理性批判》中占有十分重要的地位。康德试图以把因果问题归结为先天综合判断何以可能的方式来解决因果问题。这样,使先天综合判断得以可能的先验自我就成为因果必然性的最高的先天依据。康德这一解决因果问题的做法使其在一定程度上回到了亚里士多德的本体学说并受到后世哲学的批判。本文指出,康德虽然并未能成功地解决因果必然性问题,但是其解决因果问题所采取的理论路向依然对后世哲学具有十分重要的启示意义。 The issue of cause and effect occupies a very important position in Kant’s Critique of Pure Reason. Kant tried to solve the problem of causality in a way that attributed the question of cause and effect to the possibility of a priori and comprehensive judgment. In this way, the transcendental ego, which enables a priori synthetic judgment, becomes the highest natural basis of the causal necessity. Kant, a solution to the problem of causation, made it to a certain extent return to Aristotle’s ontology and was criticized by later philosophy. This article points out that though Kant failed to successfully solve the problem of causation necessity, its theoretical direction to solve causal problems still has very important implications for later philosophy.
