Q: If space is an a priori form of intuition, how can Kant claim that it has empirical reality as at A28/B44? A: Space is a priori in that its source is human sensibility, not experience. But space is empirically real in the sense that it is a component of the world of experience, as the mind's contribution to experience. Q: What does Kant mean when he says that space is an infinite given magnitude (A25/B39)? A: Kant uses the infinitude of space to show that space is not a general concept, but an intuition , and hence a "given" magnitude. General concepts have an infinite number of possible things under them (in their "sphere"). The concept 'body' comprehends potentially infinitely many bodies. But the infintude of space is that of infinitely many spaces together making up one space. Q: If space is an intuition, why does Kant refer to it as a concept? A: Space is indeed
