10 THE WORLD-ENERGY 



" object" has been merely the occasion. But the image 

 can no more be dissociated from space. than can the object 

 of which it is the image. In any sensation there is an 

 interfusion of a given subject or mind, with a given 

 object or definite quality of matter, and the product of 

 this interfusion is an "image." So that while the image 

 is a subjective fact, it has also an objective origin. It is 

 a creation of the mind and in the mind, but is neverthe- 

 less subject to the limitations characterizing the material 

 out of which it is created. Act-of-sensation and object- 

 of-sensation are the necessary complementary factors of 

 every possible sensation. Whence, in every sensation, as 

 well as in every product of sensation, both subjective 

 characteristics and objective characteristics necessarily 

 inhere. 



Thus space is seen to be a necessary condition of both 

 object and act of sensation. In so far, therefore, as it is 

 a necessary condition of the object of sensation, space is 

 objective; while in so far as it is a necessary condition of 

 the purely mental act of sensation, space is subjective. 

 It is neither exclusively the one nor exclusively the other, 

 for the reason that it is both the one and the other. 



The objective and the subjective, let us repeat, are 

 but complementary aspects of every knowable that is, 

 of every possible fact. 



It is to be noted, however, that, considered objectively, 

 space is a purely negative factor. It has no positive 

 characteristics or properties. It is pure void, and as 

 such can be known only as relation of externality between 

 object and object, or between part and part of a given 

 object ; though this latter case can, of course, be resolved 

 into the former, since the moment one's attention is
