SEX BIOLOGY AND PSYCHOLOGY i6i 



it helped elicit song and music from mere sounds 

 and noises ; it moulded our own bodies, coloured our 

 lips and eyes, and everywhere helped in adding grace 

 to mere serviceableness ; it saw to it that, as St. Paul 

 puts it, ' even our uncomely parts have an abundant 

 comeliness.' But, as we have just pointed out, its 

 connection with the mind's higher centres was in all 

 pre-human forms still temporary, under the control of 

 cyclical physiological changes, and the mind as a whole 

 was still constructed 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 

 concerns a further development of mind and a con- 

 sequent fresh mode of connection of sex with mental 

 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.
