Thus far in the Aesthetic Kant has been seen to argue that space and time, unlike anything else in intuition, are presupposed for experience of objects, and so not derived from experience.
As noted in the previous chapter, Kant makes a further and even stronger claim about space and time in the Aesthetic. Right at the beginning of the Aesthetic, he asks:
What, then, are space and time? Are they real existences? Are they only determinations or relations of things, yet such as would belong to things even if they were not intuited? Or are space and time such that they belong only to the form of intuition, and therefore to the subjective constitution of our mind, apart from which they could not be ascribed to anything whatsoever?
