EVIDENCE FOR EVOLUTION 15 



attempt is made to account for man s rational powers, 

 f by gradual modification and development from the 

 lower animals/ 1 On the other hand, manifest gain 

 has accrued from spread of the spirit of observational 

 science within the province of mental philosophy. 

 Bain, Spencer, Sully, Ladd, Lloyd Morgan, Komanes, 

 and many more have laid us under special obligations, 

 while Wundt and Miinsterberg, and Helmholtz and 

 Ferrier, have opened up the whole field of experiment 

 connected with the sensory and motor systems, as 

 these are related with experience and intelligent 

 interpretation. Observations have thus accumulated 

 on the borderland where sensibility meets conscious 

 ness. Much has here been done in elucidation of 

 the organic conditions of human experience. But, 

 valuable as is such work, it leads us only a little way 

 towards solving the perplexing problems concerned 

 with man s origin. A fresh survey of animated 

 existence is required from the new stand-point 

 afforded by the theory of Evolution. We need to 

 see things in true perspective, from man s central 

 position in Nature. In finding levels for the new 

 pathway of science, after alluvial deposit has been 

 cleared off, and the hard clay has been pierced, we 

 face the mountain. 



The difficulties encountered by Darwin at the out 

 set were largely occasioned by the novelty, even the 

 perplexing strangeness, of the problem. Common 

 observation, while including the most serviceable 

 facts, had not suggested research in the direction 

 which Darwin took. Ordinary observers sought im 

 mediate advantages ; did not at all concern themselves
