in THE SCIENTIFIC MIND 55 



of King Arthur's knights, Sir Galahad, was a complete 

 vision of the Holy Grail vouchsafed ; and he was the 

 single knight that could say : 



My strength is as the strength of ten, 

 Because my heart is pure. Tennyson. 



The secrets of Nature are likewise reserved for those 

 who seek them purely for the love of truth and desire 

 for understanding. The " just and faithful knight " can 

 see Nature unveiled and pass into the spiritual city of 

 science, where purer joys than all earthly fame can give 

 will be his prize.
