WHAT IS PHYSICAL LIFE 



creature at the crib has quite a sufficient 

 reason for being content with his unvary- 

 ing food, namely, because he is an ass ! 



JBut the same discontent with what he 

 has got Man shows with all his other 

 senses. None of them come up to what 

 he requires of them. The other animals, 

 all of whom have the same sense organs 

 that he has, find these perfectly satis- 

 factory for all their wants, but man finds 

 his to be such poor instruments for him 

 that he has to supplement the most im- 

 portant of them with devices of his own 

 making. For he demands of his bodily 

 senses what no other creature would think 

 of asking: things to be seen which no eye 

 was ever made to see, nor ear to hear, nor 

 touch to feel. Finally, in his insatiable 

 quest for information he parts company 

 with his sense organs altogether, with the 

 result, as we shall see, of incalculable ad- 

 ditions to his knowledge.
