A true announcement of the law of creation, if a man were found worthy to declare it, 

 would carry art up into the kingdom of nature, and destroy its separate and contrasted 

 existence. The fountains of invention and beauty in modern society are all but dried up. 

 .... Now men do not see nature to be beautiful and they go to make a statue which 

 shall be. — Emerson, Essay on Art.
