康德的时间概念是打开康德哲学体系之门的钥匙。通过对以牛顿和莱布尼茨为代表的两大时间学说进行了主体性的改造,康德建立了自己的先验性的主体性时间观念。时间是先天的纯粹直观形式,它是先天的,与物自体无关,一切现象必须以之为前提;时间是连结纯粹概念和纯粹直观杂多的中介。康德的时间概念,其积极意义在于它对哲学史上的时间范畴进行了转变,而时间的中介性所蕴含的先天综合判断的证明,则展示了对知识来源问题的一种新的解答;其局限性在于导致了不可知的信仰主义以及时间的绝对化,而割裂之后结合的研究方法则导致了诸多问题的产生。 Kant’s concept of time is the key to opening the door to Kant’s philosophy. Through the subjective transformation of the two major theories of time represented by Newton and Leibniz, Kant established its own transcendental subjective time concept. Time is a purely innate form of intuition. It is innate. It has nothing to do with the thing itself. All phenomena must be premised on it. Time is an intermediary that links pure concepts with purely intuitive omnibus. The positive meaning of Kant’s concept of time is that it changes the category of time in the history of philosophy, while the proof of innate comprehensive judgment contained in the temporal intermediation shows a new solution to the problem of the source of knowledge; its limitation Sex is the result of unknowable beliefs and the absoluteness of time, and the combination of research methods after fragmentation leads to many problems.
