COSMIC PHILOSOPHY 



extension in space — the most striking charac- 

 teristic of intellectual progress being the ability 

 of civilized man to adapt his inferences and ac- 

 tions to remote contingencies. Side by side with 

 these facts, comparative anatomy shows us that 

 the cerebrum and cerebellum at first keep pace 

 with each other in growth ; but as we reach 

 those higher mammals which exhibit some de- 

 gree of foresight, we find the cerebrum out- 

 growing the cerebellum and overlapping it, — 

 while in man the growth of the cerebrum has 

 been so great as to render comparatively insig- 

 nificant all other changes in the nervous system. 

 With the enormous cerebrum of civilized man 

 we may further contrast the preponderant cere- 

 bellum in those carnivorous birds whose psy- 

 chical life consists chiefly in the coordination 

 of those extremely complex and remote space 

 relations involved in the swooping upon prey 

 from great distances. The human cerebellum is 

 absolutely larger than that of such birds ; but 

 its smallness relatively to the cerebrum is a fact 

 parallel with the simplicity of the space relations 

 which man coordinates, as compared with the 

 time relations. Among the latter are comprised 

 all our ideas of cause, motion, progress, — in a 

 word, all manifestations of force which involve 

 the relation of sequence. But these ideas make 

 up by far the largest and most heterogeneous 

 portion of our psychical life.
