122 MR. DARWIN'S CRITICS v 



Mr. Wallace and Mr. Mivart go much further 

 than this. They are as stout believers in evolution 

 as Mr. Darwin himself; but Mr. Wallace denies 

 that man can have been evolved from a lower 

 animal by that process of natural selection which 

 he, with Mr. Darwin, holds to have been sufficient 

 for the evolution of all animals below man ; while 

 Mr. Mivart, admitting that natural selection has 

 been one of the conditions of the evolution of the 

 animals below man, maintains that natural se- 

 lection must, even in their case, have been supple- 

 mented by " some other cause " of the nature of 

 which, unfortunately, he does not give us any idea. 

 Thus Mr. Mivart is less of a Darwinian than Mr. 

 Wallace, for he has less faith in the power of 

 natural selection. But he is more of an evolutionist 

 than Mr. Wallace, because Mr. Wallace thinks it 

 necessary to call in an intelligent agent a sort of 

 supernatural Sir John Sebright to produce even 

 the animal frame of man; while Mr. Mivart re- 

 quires no Divine assistance till he comes to man's 

 soul. 



Thus there is a considerable divergence between 

 Mr. Wallace and Mr. Mivart. On the other hand, 

 there are some curious similarities between Mr. 

 Mivart and the Quarterly Reviewer, and these 

 are sometimes so close, that, if Mr. Mivart thought 

 it worth while, I think he might make out a 

 good case of plagiarism against the Reviewer, who 

 studiously abstains from quoting him.
