to deal with the ultimate problem. It is the plain bounden duty of the bioloigst 

 to pursue his course unprejudiced by vitalistic hypotheses, along the road of 

 observation and experiment, according to the accepted discipline of the natural 

 and physical sciences. . . It is an elementary scientific duty, it is a rule that 

 Kant himself laid down, that we should explain, just as far as we possibly can, 

 all that is capable of such explanation, in the light of the properties of matter and 

 of the forms of energy with which we are already acquainted." (Presidential 

 address before the Zoological Section of the British Association for the Advance- 

 ment of Science, 1911.)
