32 EVOLUTIONS OF ORGANIZATION. 
tions are subjected in the vegetable kingdom to 
the service of nutrition and reproduction; while 
in the animal kingdom nutrition and reproduc- 
tion give way in importance to the develop- 
ment of intelligence. And, however imperfectly 
zoologists may yet agree as to the evolutions in 
detail in different parts of the animal kingdom, it 
is plain that in the human form an organism has 
at last appeared constituting an abode of intelli- 
gence such as exists in no other, and that in man 
alone intelligence reaches the capability of ascend- 
ing beyond the wants of the physical organism in 
the contemplation of abstract truth. 
This organism, I repeat, has not improved with 
the progress of discovery in modern science, but 
was at least as complete in the heroes of antiquity 
as in those of recent times. It is surely, then, an 
assumption to suppose that evolution as distin- 
guished from variation in animal forms must go on 
unchecked till astronomic change shall have ended 
the capability of this world to support life. It is 
far more probable that the evolutions of the future 
are to be sought in realms with which the zoologist 
acknowledges that he has nothing to do, and take 
origin out of the special psychical characters of 
man. 
For my own part I maintain that the universe,
