THE VALUE AND SERVICE OF ZOO- 

 LOGICAL SCIENCE' 



SPIRITUAL VALUES 



The material values of science are often 

 heralded, while its spiritual values pa.ss un- 

 noticed. Leaving all tangible values un- 

 emphasized, we shall here contend that the 

 intangible values of science in general and 

 of zoology in particular are the more sig- 

 nificant. These we maj' characterize as 

 "spiritual," using the term over against 

 "material" and without further implica- 

 tion. Thus, if we speak of man's spiritual 

 j-earnings in contrast with his material 

 needs, we maj- not have a clear idea of what 

 this phra.se implies, but we recognize in this 

 contrast the existence of something the 

 opposite of material. That which consti- 

 tutes "the spirit of the man" is too illusive 

 for definition, yet it is a thing we recognize 

 as existent and in such a sense the word 

 spiritual is used. 



In the present world crisis there are none 

 who decry the material values of science. 

 Our very national existence depends upon 

 them. But there are many who raise the 

 question whether science on its spiritual 

 side is not a failure, whether the war is not 

 science gone mad ; and we scientists need to 

 consider what is the source of this under- 

 current of criticism which sets against the 

 freedom of science. In the eyes of the man 

 in the street, science represents only mate- 

 rial accomplishment and even among the 

 educated such a belief is not uncommon. 

 We men of science do not believe this. Wliy 

 should others? Perhaps we are to blame
