 only in the light of the evolutionary history of 

 man as indicated by the structure and functions 

 of the lower animals. 



We have not, even yet, fully appreciated the

 Unless we recognise this fundamental truth, how- 

 ever much we may add to our accumulations of 

 detailed knowledge, we shall make little progress 

 in our philosophical interpretation of the laws of 

 life, and shall encounter many unnecessary diffi- 

 culties in endeavouring to apply our knowledge 

 for the material and intellectual welfare of man- 

 kind. 



It is, I take it, one of the main functions of our 

 universities to secure the adequate representation, 

 in their curricula and in their schools of research, of 

 all departments of learning, though some doubt 

 may be entertained as to whether the applications 

 of science to human needs might not be more appro- 

 priately dealt with in special schools of technology. 

 To this point I hope to return later on. It is 

 no less important that within each of the main
