"It must not be forgotten that although a high standard of morality
gives but a slight or no advantage to each individual man and his
children over the other men of the same tribe, (...) an increase in
the number of well-endowed men and advancement in the standard of
morality will certainly give an immense advantage to one tribe over
another."
