The Structural Unity between Time and the Transcendental Ego in Kant’s Critique of Pure Reason

In this paper, the fundamental role of time in the possibility of the synthesis of the two sides of synthetic a priori judgment or pure synthesis, i.e. the pure intuition and the pure concept, will be discussed, in order to reveal the structural unity between them based on their common ground. The possibility of the pure synthesis indicates the possibility of unifying time as the pure comprehensive intuition on the one hand and pure Ego as the transcendental unity of apperception on the other. The unity of apperception on its part is the ground of the unity of all concepts of the understanding. The transcendental imagination unifies pure intuition and pure concept, thus the sought structural unity appears in the structure of the transcendental imagination as the mediation between receptivity of the intuition and spontaneity of the understanding. We attempt in this paper to disclose the possibility of this mediation and thus – with reference to Heidegger’s interpretation of the Kantian transcendental imagination - the original and unspoken structural unity between time and the transcendental Ego on the basis of the fundamental structure of pure intuition of time as self-affection or spontaneous receptivity. According to this structure, Kant’s transcendental philosophy can be founded on the subjectivity of finite subject.
