point out that in the Theory of Relativity Space and Time 

 are not metaphysical conceptions or forms. The infinite 

 homogeneous Space and Time which to Kant were mental 

 presuppositions and preconditions of all sensuous experi- 

 ence, and to Leibniz the pre-established permanent uni- 

 versal order of co-existence and succession among things, are 

 to Einstein mere limiting pseudo-concepts, metaphysical ab- 

 stractions without relation to our real experience. In our 

 experience Space and Time are given elements just as colour, 

 weight, and the rest. The task of science is to co-ordinate 

 these elements in an intelligible form, and in doing so Ein- 

 stein has simply explored them as if they were real physical 

 experience like the rest. The result is the elimination of 

 certain historic errors from the concepts of Space and Time, 

 and the determination of their physical qualities in line 

 with the rest of our physical experience and concepts. The 

 Space-Time continuum, instead of being a vague, homo- 

 geneous, formless, metaphysical concept, becomes a part of 

 physical reality, becomes the " field " of the material world, 

 with a definite structure of its own. Structure, real differ- 

 entiated structure, becomes the inmost form of the real 

 Space-Time world. The close bearing of this on the main 

 argument of this work will appear from the following 

 chapters.
