Space is not empirical, must be presupposed. Space is not a general concept of things in general, but a pure intuition .
Space is represented as an infinite given magnitude.
Space does not represent any property of things in themselves or in their relation to one another. Space is nothing but the form of all appearances of outer sense. Time is not empirical. Time is a necessary representation that underlies all intuitions and therefore is a priori . Time has only one dimension, different times cannot be simultaneous.
