44 THE ORIGIN OF LIFE 



" The torch, of imagination is as necessary to him 

 who looks for truth, as the lamp of study, Kepler 

 held both, and more than that, he had the star of 

 faith to guide him in all things from darkness unto 

 light.' " 



It is this combination of imagination and exact- 

 ness, of knowledge and of speculation, that forms 

 the basis of that principle which is to guide us in 

 the discussions that are to come.
