52 GOETHE'S " FARBENLEHRE." 



the enormous industry of the poet ; showing at the same 

 time an absence of that scientific definition which he 

 stigmatised as "pedantry " in the case of Newton. 



In connection with his subject, Goethe charged him- 

 self with all kinds of kindred knowledge. He refers 

 to ocular spectra, quoting Boyle, Buffon, and Darwin; 

 to the paralysis of the eye by light; to its extreme 

 sensitiveness when it awakes in the morning ; to irradia- 

 tion quoting Tycho Brahe on the comparative apparent 

 size of the dark and the illuminated moon. He dwells 

 upon the persistence of impressions upon the retina, 

 and quotes various instances of abnormal duration. He 

 possessed a full and exact knowledge of the phenomena

 the following striking illustration of these subjective 

 effects. " I once," he said, " entered an inn towards 

 evening, when a well-built maiden, with dazzlingly 

 white face, black hair, and scarlet bodice and skirt came 

 towards me. I looked at her sharply in the twilight, 

 and when she moved away, saw upon the white wall 

 opposite, a black face with a bright halo round it, while

 of a beautiful sea-green." With the instinct of the 

 poet, Goethe discerned in these antitheses an image of 

 the general method of nature. Every action, he says, 

 implies an opposite. Inhalation precedes expiration, 

 and each systole has its corresponding diastole. Such 

 is the eternal formula of life. Under the figure of
