SPACE AS A THOUGHT-CATEGORY 171 



denominate love, justice, colour, distance. But 

 whether the occurrence be due to change of state or 

 of position, we perceive it as a transformation within 

 an aggregate of sense impressions. In order, then, 

 to reduce the realm of consciousness to unity, each 

 cause must work uniformly with the others: that is, 

 be expressible in terms of the others. And since 

 what lawdom the mind has thus far achieved is based 

 on spatial relations, the hyper-space theory offers 

 the quickest method to the systematisation of experi- 

 ence. 



The scientist is finding that, as he studies matter 

 more closely, he has need of other dimensions than 

 the conventional three. While the larger movements 

 of the physical realm are still duly categorised on the 

 hypothesis of a three-dimensional space, there are 

 other movements within the minute structure of or- 

 ganisms which require a finer net for their snaring. 

 But given the proper leeway, a molecular force takes 

 on the aspect of a motor force and is quickly classi- 

 fied. 



Psychic phenomena are fast yielding to measure- 

 ment, as the psychological laboratories of our uni- 

 versities attest. That things transcendental will 

 give up their mystery with a larger spatial outlook is 

 highly probable in view of the analogy obtaining be- 

 tween spiritual laws and fourth-dimensional proper- 

 ties. Mr. Hinton found, for instance, that the first 

 requisite to higher space perception was the doing
