118 The Higher Usefulness of Science 



alization of the facts of form." 



A prime object of this paper is to contend that 

 biology has now reached a stage in its progress where 

 we can no longer restrict our dictum "neglect nothing" 

 to morphological attributes, as the above quotation 

 seems to take for granted, but must extend it to all 

 attributes of organisms whatever morphological, 

 physiological, ecological, chemical and all the rest. 

 And it should be pointed out that the movement of 

 biology in this direction was more or less distinctly 

 seen by at least one biologist nearly a century ago, 

 namely, G. R. Treviranus. "The doctrine of organiza- 

 tion," he said, "is founded upon comparative anatomy, 

 or the systematic distribution of living bodies, and on 

 organic chemistry." 



I believe a comprehensive review of the whole range 

 of biological results won during the last five-and-twenty 

 years, let us say, will convince any one that each of the 

 main provinces of research comparative physiology, 

 ecology, experimental behavior, genetics and biochem- 

 istry, no less than histology, cytology, embryology and 

 regeneration, would furnish differentia for a classifica- 

 tion of the organisms used in the researches ; or at least 

 that they contain differentia corresponding to the sys- 

 tems of classification previously established on the basis 

 of pure morphology. 



What does this signify for the attitude of biologists 

 toward their problems, and for methods and enterprises 

 of research?
