 The diamond looks like a pebble until it is cut. 

 One goes to Nature only for hints and half truths. 

 Her facts are crude until you have absorbed them 

 or translated them. Then the ideal steals in and 

 lends a charm in spite of one. It is not so much 

 what we see as what the thing seen suggests. We

 and gather fruit that is ripe for the palate without 

 any aid of yours, but you cannot do this in science 

 or in art. Here truth must be disentangled and 

 interpreted, must be made in the image of man. 

 Hence all good observation is more or less a refining 

 and transmuting process, and the secret is to know

 the poet; before it can become science, it must pass 

 through the understanding of the scientist. Or one 

 may say, it is with the thoughts and half thoughts
