llectual ancestry, it is likely that she
herself will carry such traits germinally, even if she has never had an
opportunity to develop them. She can, then, pass them on to her own
children. Francis Galton long ago pointed out the good results of a
custom obtaining in Germany, whereby college professors tended to marry
the daughters or sisters of college professors. A tendency for men of
science to marry women of scientific attainments or training is marked
among biologists, at least, in the United States; and the number of
cases in which musicians intermarry is striking. Such assortative mating
means that the offspring will usually be well endowed with a talent.

Finally, young people should be taught a greater appreciation of the
lasting qualities of comradeship, for which the purely emotional factors
that make up mere sexual attraction are far from offering a satisfactory
substitute.

It will not be out of place here to point out that a change in the
social valuation of reputability and honor is greatly needed for the
better working of sexual selection. The conspicuous waste and leisure
that Thorstein Veblen points out as the chief criterion of reputability
at present have a dubious relation to high mental or moral endowment,
far less than has wealth. There is much left to be done to achieve a
meritorious distribution of wealth. The fact that the insignia of
success are too often awarded to trickery, callousness and luck does not
argue for the abolition altogether of the financial success element in
reputability, in favor of a "dead level" of equality such as would
result from the application of certain communistic ideals. Distinctions,
rightly awarded, are an aid, not a hindrance to sexual selection, and
effort should be directed, from the eugenic point of view, no less to
the proper recognition of true superiority than to the elimination of
unjustified differentiations of reputability.

This leads to the consideration of moral standards, and here again
details are complex but the broad outlines clear. It seems probable that
morality is to a considerable extent a matter of heredity, and the care
of the eugenist should be to work with every force that makes for a
clear understanding of the moral factors of the world, and to work
against every force that tends to confuse the issues. When the issue is
clear cut, most people will by instinct tend to marry into moral rather
than immoral stocks.

True quality, then, s
