FALLING m LOVE 5 



A pleasant smile half redeems unattractive features. Low, 

 receding foreheads strike us uniavourably. Heavy, stolid, 

 half-idioti(; countenances can never be beautiful, however 

 regular tiieir lines and contours. Intelligence and good- 

 ness are almost as necessary as health and vigour in order 

 to make up our perfect ideal of a beautiful hmnan face and 

 figure. The Apollo Belvedere is no fool ; the murderers in 

 the Chamber of Horrors at Madame Tussaud's are for the 

 most part no beauties. 



What we all fall in love with, then, as a race, is in most 

 casf^s efficiency and ability. What we each fall in love 

 with individually is, I beheve, our moral, mental, and

 extended range of cases, may, I think, be almost demon- 

 strated by sure and certain warranty of human nature. 



Brothers and sisters have more in common, mentally

 can possibly have with one another. But nobody falls in 

 love with his sister. A profound instinct has taught even 

 the lower races of men (for the most part) to avoid such 

 union of the all-but-identical. In the higher races the idea 

 never so much as occurs to us. Even cousins seldom fall 

 in love — seldom, that is to say, in comparison with the 

 frequent opportunities of intercourse they enjoy, relatively 

 to the remainder of general society. When they do, and 

 when they carry out their perilous choice effectively by 

 marriage, natural selection soon avenges Nature upon the 

 offspring by cutting off the idiots, the consumptives, the 

 weaklings, and the cripples, who often result from such 

 consanguineous marriages. In narrow communities, where
