Time is therefore given a priori. In it alone is all reality of phenomena possible. These may all be annihilated in thought, but time itself, as the universal condition of their possibility, cannot be so annulled. These principles cannot be derived from experience, for it would give neither strict universality, nor apodeictic certainty. Time is not a discursive, or as it is called, general conception, but a pure form of the sensuous intuition.
Different times are merely parts of one and the same time.
But the representation which can only be given by a single object is an intuition. Besides, the proposition that different times cannot be coexistent could not be derived from a general conception. For this proposition is synthetical, and therefore cannot spring out of conceptions alone. It is therefore contained immediately in the intuition and representation of time. The infinity of time signifies nothing more than that every determined quantity of time is possible only through limitations of one time lying at the foundation.
