 Every good thing begins as something else, and what 

 was intended for the common people became scientific 

 lectures for educated people. "The man who was 

 most benefited by these lectures was myself," said 

 Humboldt. 



Men grow by doing things. Lectures are for the lec- 

 turer. Humboldt found out more things in giving these 

 lectures than he knew before he discovered himself. 

 And long before they were completed he knew that 

 his best work was embodied right here in doing for 

 others he had done for himself. 

 In attempting to reveal the Universe or " Kosmos " he 

 revealed most of his own comprehensive intelligence. 

 That many of his conclusions have since been aban- 

 doned by the scientific -world does not prove such 

 ideas valueless they helped and are helping men to 

 find the truth. 

 These sixty-one "popular" and free lectures makeup 

 the gigantic work known as " Humboldt's Cosmos."
