EVOLUTION THE MASTER-KEY

 being regarded as the knovvable reality. This 

 doctrine has taken many forms. The oldest and 

 crudest is that which regards mind as a proper

 physics has shown matter to be no more than a 

 fleeting manifestation of something else, material 

 ism in its crudest form has been abandoned. This 

 solution was, indeed, never other than fallacious, 

 since, as the distinguished French scientist M. Poin- 

 care&quot; remarks, 1 it is meaningless to assert that mind 

 is a property of something which, on analysis, can 

 only be regarded as symbolic. 



Therefore the modern successors of the materi 

 alistic theory are framed in somewhat less vulner 

 able terms. Here, then, we may resume considera 

 tion of one of these quasi-materialistic theories, 

 which is, at any rate, no worse than any of its 

 fellows. 



It is an easy thing to dissect a human brain. 

 The post-mortem-room attendant preserves it in 

 formalin or alcohol and sells it to the student, who 

 proceeds with a long knife to slice it from above 

 downward, examining each section seriatim. He 

 can also make microscopic sections of the gray 

 matter from various areas, stain them with silver 

 salts, and examine them under a high power. He 

 thus is certain to encounter &quot;that part of the 

 sensorium capable of the greatest molecular ac-
