162 THE ANATOMY OF SCIENCE 



eagle soaring to ever greater heights by utiliz- 

 ing the slight variations of the wind? 



It may have seemed strange that in outlining 

 the contents of this work, which handle for the 

 most part concepts with which I have some de- 

 gree of acquaintance, I touch in the last chap- 

 ters upon biological problems where I have only 

 the merest smattering of information. However, 

 I shall emphasize again in the next chapter how 

 subtle the distinction is between animate and 

 inanimate nature. Certainly a glance at the 

 characteristics of living things cannot obscure 

 and may perhaps clarify our understanding of 

 some of the concepts of inorganic science.
