Rumslighet

En liten tanke av Immanuel Kant låg och skräpade längst ner i artikeln om "dimension" hos Wikipedia:

In 1783, Kant wrote:

"That everywhere space (which is not itself the boundary of another space) has three dimensions and that space in general cannot have more dimensions is based on the proposition that not more than three lines can intersect at right angles in one point.

This proposition cannot at all be shown from concepts, but rests immediately on intuition and indeed on pure intuition a priori because it is apodictically (demonstrably) certain.
