A questão do tempo originário na leitura heideggeriana da imaginação transcendental kantiana e sua relação com a meta de Ser e Tempo

In the lecture, Kant and the Problem of Metaphysics (1929), Heidegger says that Kant, in the second edition of the Critique of Pure Reason (1787), eliminates the possibility of investigating the originary time as being the unity of the two sources of knowledge (sensibility and understanding) since the transcendental imagination had ceased to have the fundamental prominence contained in the first edition of the work (1781). Thus, our aim is to understand how the transcendental imagination can be taken as a source of a priori knowledge and also, how, based on it, Heidegger thematizes the question of the temporality (Temporalität).
