EVIDENCE FOR EVOLUTION 17 



these questions, none have solved them. The number 

 of theories in mental philosophy is subject of common 

 remark: the explanation lies in the depth of the 

 problem. Scientific men and philosophers are apt 

 to laugh at each other; the laugh goes round; the 

 problems remain. A steady look into the unfathomed 

 depths will awaken misgivings as to evolution of 

 rational life from sensory existence. For a long time 

 to come, we shall have to speak of rival schools of 

 philosophy ; one school having more affinity with the 

 Darwinian theory than the other. The Experi 

 mental, or Sensational, school of philosophy may with 

 some warrant be said to have been preparing the way 

 for Darwin. This is the school which relies mainly 

 on the laws of association, connected with sensibility, 

 for interpretation of human experience; it is the 

 Sensational school which finds the sources of intel 

 lectual life in feeling. On the other hand, the 

 Rational school, the transcendentalists, who push 

 behind and beneath experience in the attempt to 

 interpret experience, make thought the pre-requisite, 

 logically and historically, for human experience. 

 They are regarded by their critics as men who are 

 boring too deeply, getting into a quite unpromising 

 region, more likely to find mineral, than to find mind. 

 This battle of the schools must be fought out here. 

 The problem of rational life cannot find solution in 

 observations concerning the lower animals, however 

 important these may prove. 



Whatever be the ultimate award as to the range of 

 Evolution in the history of life on the earth, there can 

 be only one opinion as to the high honour due to 

 Charles Darwin. Preoccupied with the clue he had
