 the Idealism of the classical to the Eealism of the exact 

 period of thought, knowledge has, even in the eyes 

 of the professedly unprejudiced thinker, acquired a

 most secluded thinkers. Two characteristics have here to 

 be noted. The rapid growth of natural knowledge, based

 already, in the eighteenth century, created a desire for 

 an analogous study of the human mind and human

 study of the problems of knowledge. But even more 

 determining for these philosophical speculations was 

 a second influence. This was the widespread atten-
