RELATIONS BETWEEN MIND AND MATTER. 99 



that matter is not what it was thought to be or to be like, that 

 its nature is as mysterious as is the nature of mind. In expe- 

 rience we find the two always associated. Experience leads to 

 the belief that one of these is imperishable, and we make it 

 a corner-stone in physical science ; and my thesis is that mind 

 can no more be sloughed off from it than can gravity or mag- 

 netism or any other of its inherent qualities.
