130 BIOLOGY AND SOCIAL PROBLEMS 



for, from whichever side of the problem we 

 make the approach, there is but one goal. 



Of the nature of living substance we are 

 only just beginning to get a dim appreciation, 

 but when this appreciation grows to some- 

 thing of an understanding, we shall feel, I be- 

 lieve, no more hesitancy in abandoning our old 

 view of the separateness of self and body and 

 accepting that of their common nature than in 

 the past our race had in giving up Dante's para- 

 dise and its ten heavens for the depths of blue 

 above us. Organized living material, as we 

 meet it in the cerebral cortex, is so strictly a 

 part of the universe and yet so strikingly dif- 

 ferent from any other aggregate of material 

 known to us that we can look upon it at pres- 

 ent only with vague bewilderment and yet with 

 a hope, justified by the past progress of sci- 

 ence, that in time its secrets will be gradually 

 disclosed to us. With such a view of the poten- 

 tialities of material, it is not surprising that 

 the biologist finds in the study of organisms 

 a subject of intense interest whose applica- 

 tion to the problems of human welfare comes 

 to be day by day more apparent and intimate.
