KANT AND EINSTEIN
===============================================================================

Einstein wrote:

"Concepts and Conceptual Systems get justified exclusively by their capacity to 
coordinate events. They cannot be justified in any other way. Therefore, it is, 
in my opinion, one of the most pernicious acts of Philosophers to have transfered 
some conceptual bases of Natural Science from the controllable domain of empiric 
adequacy into inaccessible hight of the Necessary Apriori. 
This applies particularly to our concepts of time and space, which the Physicists 
- forced by the facts - had to descend from the Olympus of Apriori in order to 
repair them and make them usable." (1)

He rather clearly meant Kant, for whom our "common sense" space and time are 
independent, aprioristic, necessary and universal (2) categories.
 
Having learnt for the first time this Einstein's opinion I discussed it with 
Tatarkiewicz, the best historian of Philosophy I ever met or read. 
In his opinion Einstein was too radical. Even if Kant's time and space proved 
useless for Physics, they preserve their value for Philosophy, where they 
contributed to the creation of modern Theory of Cognition.  
And they were not completely useless for Physics. After all, Newton had uesed, 
implicitly and by anticipation, Kant's time and space as the base of his Model.

Who is right, Kant or Einstein?

(1) Subsequently we shall use "_SPACE_" to designate this repaired and usable 
"time and space". Indeed they are both encompassed by the mathematical concept 
of _SPACE_ which Einstein certainly implied.
===============================================================================

(2) By "universal" we mean "invariant for all observers and referencials". 
We prefer it to "absolute" which is multivalued and charged with transcendental 
and theological implications.
