Ix THE DEBT OF SCIENCE TO DARWIN 475 
Newton, through which he was enabled to grasp fundamental 
principles, and so apply them as to bring order out of chaos, 
and illuminate the world of life as Newton illuminated the 
material universe. Paraphrasing the eulogistic words of the 
poet, we may say, with perhaps a greater approximation to 
truth— 
‘Nature and Nature’s laws lay hid in night; 
God said, ‘Let Darwin be,’ and all was light.”
