Full Idea
Thus the representation of space cannot be obtained from the relations of outer appearance through experience, but this outer experience is itself first possible only through this representation.
Gist of Idea
We can't learn of space through experience; experience of space needs its representation

A Reaction
There is an obvious symbiosis between the mental experience of such things as space and the nature of the thing itself, but I don't see what basis Kant can have for his confident distinction.
