42 INVOLUTION AND MAN S I LACK IN NATUHK 



intricate as in the liuniiin body, like arrangements 

 provide for sensibility and motion. In all cases, 

 there is a two-sided arrangement of nerve litres, 



\co-ordinated in a nerve centre. The organism is aeted 

 upon through its sensibilities; it reacts through the 

 motor apparatus, The primary end and object of 

 the reception of tlio influences (Nfutuili) of the 

 external world or environment, is to enable; the 

 organism to respond to those special modes of in 

 fluence or stimuli. 1 Kibres on one side provide for 

 sensibility through contact; fibres on the other side 

 provide for muscular movement in sympathy with 

 the earlier nerve movement. According to the com 

 plexity of the organic structure is a complexity of 

 correlated nerve fibres. 2 



In the human body, we find the most complex 

 sensori-molor system, working the most elaborately 

 detailed combination of muscles. The manifold 

 possibilities of work belonging to the human hand 

 itself, illustrate well the superiority of human organism. 



* Kven here intellectual superiority is already coming 

 into view, without which the worth of the instrument 

 at command would not appear as it does in our 

 common occupations. Wo do not, however, enter 

 upon this as yet. It is enough here that we remark 

 the superiority of the human body to all organic 

 existence around. Kven thus, man has a uni&amp;lt;|ue place. 

 \\ ilh this superiority of human organism, we need 

 to observe the similarity in form apparent in apes, 

 on (his account named man-like apes (Anthropoid).
