e would wake up to the paramount importance of what eugenics
means. And this could be done quietly and simply without violence to
existing ideas of what is right and proper. It could be done by
segregation of the sexes for defectives, feeble-minded, idiots,
epileptics, insane, etc. By this kind of isolation we can save the
blood-stream of our race from a tremendous amount of needless
contamination.

And it is being done. The growing tendency to put defectives in
institutions, though originally with no such object, will reduce the
transmission of defects, especially when it is recognized that the sexes
must be separated and that the inmates should be kept at the institution
through the reproductive period of life.

[Sidenote: Educational Influence]

It is inconceivable that the average individual will deliberately and
consciously make his calculations regarding the character of possible
offspring before he allows himself to fall in love to the point of
desiring marriage. Yet unconsciously an educational influence on love
and on marriage selection has been operating through centuries. The
sick, the feeble-minded, the immoral, and members of their families,
have at all times been socially handicapped, and have always been the
first to be eliminated in marriage selection. And it is conceivable that
this already developed wisdom in mate-choosing can easily be augmented
by a further knowledge of heredity which is now available. It
unconsciously favorably modifies the individual taste.

Certain races of men, without consciousness of their action, have varied
in the character of their choices (sex selection) in such a way as to
bring about varied conditions in their races, with respect to resistance
to disease, of mental capacity and to moral quality. The Mongolian
differs from the Hebrew, the Anglo-Saxon differs from the African.

It depends largely upon the action of those now upon the earth, who are
now making their choices of marriage, as to whether the races of the
future shall be physical, mental or moral weaklings, or whether they
shall be physically brave and hardy, mentally broad and profound, and
morally sterling.

[Sidenote: Summary]

To summarize: There are three main lines along which eugenic improvement
of the race may be attained:

(1) Education of all people on the inheritability of traits; (2)
segregation of defectives so that they may not mingle their family
traits with those on sound lines; (3) ster
