The Ideas on which the Pure Sciences depend, are those of Space and Number; but Number is a modification of the conception of Repetition, which belongs to the Idea of Time. (ii. 1.)

The Idea of Space is not derived from experience, for experience of external objects presupposes bodies to exist in Space, Space is a condition under which the mind receives the impressions of sense, and therefore the relations of space are necessarily and universally true of all perceived objects. Space is a form of our perceptions, and regulates them, whatever the matter of them may be. (ii. 2.)

XXIII.
Space is not a real object or thing, distinct from the objects which exist in it; but it is a real condition of the existence of external objects. (ii. 3.) 9
