EVOLUTION MADE PLAIN 47 
That the selfish person defeats his own ends, 
cheats himself, is a truism. Only the unselfish 
person, holding humanity dearer than his own 
self, enjoys to the fullest all that belongs to 
selfhood, for he alone lias the capacity for real 
enjoyment—or deserves it. The supremely 
selfish—the criminal, the grafter, the one who 
seeks to profit in any way at the expense of 
others—stands in the same relation to his race 
as the inferior animal to its species—he pulls 
down the average of the race, and is at cross 
purposes with Nature. 
To condone in one’s self any of the many 
forms of sefishness, whether it be greed, theft, 
lying, lust, or vanity, is to put one’s self in the 
same class with those defective wild creatures 
which Nature ruthlessly destroys. 
When a great ethical doctrine is grounded 
on a scientific basis it becomes doubly con¬ 
vincing. Let the whole truth in regard to each 
individual’s duty to the race be taught—the 
scientific half of it along with the emotional, 
idealistic half. No one who feels the full force 
of this truth will, in order to “make a living,” 
take out of the COMMON GOOD fund more 
than he puts into it, but less, rather. It should 
be instilled into the minds of youth that the 
welfare of the race is the supreme duty of 
each, and that the greatest individual happi¬ 
ness is attained only through the self-develop¬ 
ment and self-expression of the individual 
along this line. But, alas! the enlightened 
legislatures of some of our sovereign states 
have forbid the teaching of natural selection 
to children. The reason given is that it might 
rcb them cf their religion!
