SEX BIOLOGY AND SEX PSYCHOLOGY 161

 just pointed out, its connection with the mind's 

 higher centres was in all pre-human forms still tem- 

 porary, under the control of cyclical physiological 

 changes, and the mind as a whole was still con- 

 structed in compartments, so that different instincts 

 and different experiences did not necessarily or even 

 usually come in contact with each other. 



The next great change is being made now; it con-

 life. As we have outlined above, this change in 

 mind consists in the tendency towards uniting the 

 different parts of the psyche, both those portions 

 given by heredity and the modification due to ex- 

 perience, into a single organic whole, and in making 

 this whole more dominant over the other aspects of 

 the organism; the consequent tendency as regards 

 the relationship of sex to the organism is towards 

 taking it out of its single groove, its water-tight 

 compartment, and bringing it into more complete 

 and more permanent union with the rest of the mind. 

 Furthermore, the main change and the consequent 

 change as regards sex are both of a biologically pro- 

 gressive nature. 



We are now, I think, owing to our taking this 

 broad biological view, in a better position to make 

 up our minds as to some at least of the difficulties 

 which beset us to-day in any attempt to deal squarely 

 with the relation of sex to human life. It is true
