ix rSYCHO-rilVSICAL PHENOMENA 487 



;iiid endeavours to give some explanation of the mysterious 

 problems of heredity or the power of reproduction ;md evolution 

 manifested ly living substance, and of the different states of eon- 

 scioiisness and suhconsciousness, he readily admits that they are 

 inexplicable by the laws of atomic, and molecular mechanics, and 

 feels (he necessity of confronting materialism by vitalism. 



Both materialism, or the atomistic hypothesis, and ril<ili*in, 

 the hypothesis of vital or psychical energy, must continue to 

 function as indispensable vehicles, as the necessary poles of future 

 physiological discovery. 



"The evolutionary process of physiological science," as we said 

 in the Introduction to Vol. I. of this work, " has always been in 

 the past, and will always be in the future, a continuous and 

 fruitful struggle between the two opposite tendencies of material- 

 ism and vitalism." Both are one-sided; each reflects only one 

 aspect of the Real. The complete Theory of Lii'e must be the 

 result of their iuterpenetratioii and fusion.
