As a matter of fact, of course, there are plenty of people who accept 

 the evolution conception and do not accept Haeckel's monism. These 

 people do not see that one necessarily follows the other. Many of them 

 indeed think they see that Haeckelian monism does not follow evolu- 

 tion, that it, in fact, has no fundamental connection with it. There 

 are other people still, who are monists, but who do not accept Haeckel's 

 alleged consequences of a monistic, as opposed to a dualistic, concep- 

 tion of nature. But Haeckel undoubtedly believes all he says he does 

 and believes too in the duty of propaganda. That he has a considerable 

 following can not be overlooked.
