iv MR. DARWIN’S CRITICS 179 
give an advantage to those individuals who 
vary in the direction of intellectual or exsthetic 
excellence, what is there to interfere with the 
belief that these higher faculties, like the rest, owe 
their development to natural selection ? 
Finally, with respect to the development of the 
- moral sense out of the simple feelings of pleasure 
and pain, liking and disliking, with which the 
lower animals are provided, I can find nothing in 
Mr. Wallace’s reasonings which has not already 
been met by Mr. Mill, Mr. Spencer, or Mr. 
Darwin. 
I. do not propose to follow the Quarterly 
Reviewer and Mr. Mivart through the long string 
of objections in matters of detail which they 
bring against Mr. Darwin’s views. Every one who 
has considered the matter carefully will be able to 
ferret out as many more “ difficulties”; but he 
will also, I believe, fail as completely as they 
appear to me to have done, in bringing forward 
any fact which is really contradictory of Mr. 
Darwin’s views. Occasionally, too, their objections 
and criticisms are based upon errors of their own. 
As, for example, when Mr. Mivart and the 
Quarterly Reviewer insist upon the resemblances 
between the eyes of Cephalopoda and Vertebrata, 
quite forgetting that there are striking and alto- 
gether fundamental differences between them ; or 
when the Quarterly Reviewer corrects Mr. Darwin
