94 Can Science Explain Life? 



forces is, however, due to neutralization by in- 

 duced electric charges or magnetic poles of oppo- 

 site sign. It is readily conceivable that the same 

 force may behave like electricity or magnetism at 

 comparatively short distances, but like gravita- 

 tion at much greater distances, and that the true 

 explanation for all of these forces may be found 

 in the properties of electrical vortices. 



It appears from the foregoing that there is still 

 such an abundance of unexplored subject-matter 

 in the realm of the comprehensible that it is alto- 

 gether too soon to invoke the supposed fourth 

 dimension or other imaginary realms or super- 

 natural agencies in our efforts to explain natural 

 phenomena. Although the reliability of our men- 

 tal processes has lately fallen somewhat into dis- 

 repute as the result of recent non-Euclidean 

 mathematical adventures, yet we may confidently 

 expect that after the futility of these recent ad- 

 ventures is being realized there will be a return 

 to rational concepts. It is human nature to at- 

 tribute to supernatural causation anything which 

 cannot be understood or explained in the light of 

 contemporary scientific knowledge; but if the 

 boundaries of science will continue to expand at 

 the rate at which they have been expanding dur- 

 ing recent years, then it will be only a question of 

 time until the supposed realm of supernatural 

 causation will have vanished from existence.
