 in Europe before he removed to the United States of 

 America when thirty-nine years of age. The nobility 

 of his character, his untiring efforts to increase the 

 knowledge of science, and his inspiring personality,

 despises shams and false conventions, and exposes 

 superstition whenever it is encountered. These are 

 the standards of scientific integrity, and the man whose 

 ideals are dominated by them has found the way to 

 intellectual and spiritual salvation. 



Science seems to me to teach in the highest and strongest 

 manner the great truth which is embodied in the Christian
