GENETICS AND ETHICS 497 



This debilitating philosophy in which every- 

 thing is predetermined, in which there is no 

 possibility of change or control, in which there 

 is hypertrophy of intellect and atrophy of will, 

 is a symptom of senility whether in men or 

 nations. We need to return to the joys of a 

 childhood age in which men believed them- 

 selves free to do, to think, to strive, in which 

 life was full of high endeavor and the world 

 was crowded with great emprise. We need to 

 think of the possibilities of development as 

 well as of the limitations of heredity. Chance, 

 heredity, environment have settled many 

 things for us; we are hedged about by bounds 

 which we cannot pass, but those bounds are 

 not so narrow as we are sometimes taught and 

 within them we have a considerable degree of 

 freedom and responsibility. ' 



"That which we are we are, 

 One equal temper of heroic hearts 

 Made weak by time and fate, but strong in will 

 To strive, to seek, to find, and not to yield."
