Abstract: Kant，in Heidegger’s explanatory strategies，is a crutch in the process of Heidegger searching for being.Everything，in searching for being，must be guided by searching for man.Transcendental imagination is the region which gave objects to human as finite domain，and Heidegger bursts out existence on the basis of Kant’s transcendental imagination.In Kant’s fundamental spirit，human establish congenital dimension and frame for nature in the recognizing respect because transcendental imagination as a hard form was incorporated.But Heidegger thinks that nature is the foundation of human existence，and finally nature will not be restricted by human activities because of its inner measure.In the process of searching for being and trying to strip the will of human to fully control nature，which is embodied in Kant’s cognitive activities，Kant’s transcendental imagination is dispelled and evolved in Heidegger’s philosophy.
