BIOLOGY IN HUMAN AFFAIRS 



of endowments. And even there it is far more significant 

 that such selection as diminishes the proportion of women 

 students in law and engineering to nearly zero, as deter- 

 mines what branches within the academic program attract 

 women and in which they excel; that women in general are 

 as musically inclined as men if not more so, yet few 

 women become composers; that the stage arts in which 

 personality counts, are the ones in which women hold 

 their own; that by far fewer women carry their proficiencies 

 (writers excepted, again in the field in which personalized 

 human relations count) to a professional status — all this is 

 certainly of far larger consequence than a set of proficiencies 

 which happen to be more measurable by the aid of assump- 

 tions. The confusion of measurability with importance is 

 the experimentalist's fallacy. It can be corrected only by 

 loyalty to the scale — if we can but learn to read it — of 

 nature's significance. The arguments thus suggested pro 

 and con are fragmentary; they are sufficient to indicate an 

 approach to the solution of the problem involved by way 

 of a naturalistic appraisal. It will then be found that men 

 and women are even more profoundly and variously differ- 

 ent than we have yet discovered. How could it be other- 

 wise, since the principle of physiological psychology is 

 that bodily functions are reflected in psychic ones in all 

 degrees of radiation; and there is no deeper and more 

 pervasive physiological difference than that which divides 

 human beings (abstractions) into men and women (as 

 realities). Confusion results from neglect of this distinction. 

 Such a principle as the Adlerian "masculine protest" is 

 left floating in mid-air when applied to women. In the 

 future we may recognize a masculine and a feminine 

 psychology. The practical bearings of it all upon adapting 

 the social and industrial arrangements of the world to the 

 needs of men and women are vast. Circumstance will 

 continue to shape institutions. But there is no problem
