Apriority and Spontaneity in Critical Philosophy of I. Kant.

The concept of a priori knowledge, which is central in Kant's philosophy, is considered in connection with the idea of the spontaneous character of intellectual cognitive faculties. In major critical works the thesis about the spontaneity is expounded with certain restrictions concerning the difference of absolute and relative spontaneity, its incomprehensibility and timelessness, the attribution to a nournenal subject. However, in the philosopher's manuscript heritage the thesis is often interpreted as an essential characteristic of God's a priori knowledge that is "archetypical" for human cognition, which has features of originator-function of phenomena and specific mode of pure concepts formation.
