AS THE BIOLOGIST SEES IT 



happen unless we stepped off the track, 

 and that pretty quickly. 



The biologist is a homely and practical- 

 minded person who is little given to over- 

 refined logic and debate but much given 

 to observation and experiment. He be- 

 lieves that his eyes and ears and brain 

 help him to the saving and enjoyment of 

 life by enabling him to know and adapt 

 his behavior to the world he lives in. 

 The man who makes the world all mental 

 may have reached a higher kind of 

 Weltanschauung than the biologist, but 

 the biologist, as far as I know him, 

 is not going yet, for the sake of ascend- 

 ing to this higher plane, to give up 

 remembering what happened to the man 

 who doesn't step off the track, nor will 

 he give up keeping his leg muscles in trim 

 for a quick jump. His low and materi- 

 alistic Weltanschauung is perhaps suffi- 

 ciently indicated by his using as argument 

 his readiness to bet his life and his enjoy- 

 ment of life on what he thinks he knows 

 about the reality of matter and energy.
