pronounced, but in all cases, the variation must be confined to the
possible combinations of characters transmitted from parents and ancestors.

_The law of regression_ represents the tendency of the extreme elements of
the race constantly to seek the middle or mediocre level. For example, the
children of superior parents are not likely to be so brilliant as their
parents, and the offspring of inferior people are somewhat better than
their parents. This "drag of the race" or "pull of ancestors" is no doubt
due to the fact that selection has never been practiced, hence the
two-thousand nearby ancestors were most likely an average lot of people,
and the "pull" is from the higher towards the lower level. The "pull" is a
help to the children of inferior parents but is a handicap to the superior.

If long-continued selection of parents were practiced, the regression
would disappear and the "pull" would be upward. Selection of parents
possessing superior elements of character and the prevention of the unfit
and the criminal from propagating their kind, seem the surest hope we have
of producing a permanently higher type.

It is well known that the extremes of the race are less fertile than the
means; and since fertility is the chief factor in fixing the type, in the
absence of selection and repression, the race appears doomed to remain at
the dead level of mediocrity. The tremendous significance of this fact is
that the welfare of the race--the gradual substitution of a superior for
the present mediocre type--rests absolutely upon the willingness and
ability of the superior class to do their full share in propagating the
race.
