spatial dimensions of things, except in so far as they 

 appear in our consciousness. 



The proposition that all things are side by side in 

 Space is true only under the limitation that we are 

 speaking of our own sensible perception. But if we 

 more exactly define the subject of the proposition by 

 saying that all things as external phenomena are side 

 by side in Space, it will be true universally and 

 without any exception. 



We therefore affirm the empirical reality of Space as 

 regards all possible external experience ; but we also 

 maintain its transcendental ideality ; or, in other words, 

 we hold that Space is nothing at all if its limitation 

 to possible experience is ignored, and it is treated as 

 a necessary condition of things in themselves" l 



Kant's conclusion as to Time is exactly similar : 

 " We deny to Time all claim to absolute reality, 

 because such a claim, in paying no heed to the form 

 of sensible perception, assumes Time to be an absolute 

 condition or property of things. Such properties, 

 as supposed to belong to things in themselves, can 

 never be presented to us in sense. From this we 

 infer the transcendental ideality of Time ; by which we 

 mean that, in abstraction from the subjective condi- 

 tions of sensible perception, Time is simply nothing,
