"Strong and changing
emotions, an improvident character and a tendency to immoral conduct are
not unallied," he explains; "They are all rooted in uncontrolled
impulse. And a factor which may tend to produce all three is a deficient
development of the more purely intellectual capacities. Where the
implications of the ideas are not apprehended, where thought is not
lively and fertile, where meanings and consequences are not grasped, the
need for the control of impulse will not be felt. And the demonstrable
deficiency of the Negro in intellectual traits may involve the dynamic
deficiencies which common opinion claims to exist."
There are other racial and heritable differences of much importance,
which are given too little recognition--namely, the differences of
disease resistance. Here one can speak unhesitatingly of a real
inferiority in respect to the environment of North America.
As was pointed out in the chapter on Natural Selection, the Negro has
been subjected to lethal selection for centuries by the Negro diseases,
the diseases of tropical Africa, of which malaria and yellow fever are
the most conspicuous examples. The Negro is strongly resistant to these
and can live where the white man dies.
