that the state can not interfere with an
individual matter of this sort: "It is an intolerable invasion of
personal liberty; it is reducing humanity to the level of the barn-yard;
it is impossible to put artificial restraints on the relations between
the sexes, founded as they are on such strong and primal feelings."

The doctrine of personal liberty, in this extreme form, was enunciated
and is maintained by people who are ignorant of biology and
evolution;[79] people who are ignorant of the world as it is, and deal
only with the world as they think it ought to be. Nature reveals no such
extreme "law of personal liberty," and the race that tries to carry such
a supposed law to its logical conclusion will soon find, in the supreme
test of competition with other races, that the interests of the
individual are much less important to nature than the interests of the
race. Perpetuation of the race is the first end to be sought. So far as
according a wide measure of personal liberty to its members will compass
that end, the personal liberty doctrine is a good one; but if it is held
as a metaphysical dogma, to deny that the race may take any action
necessary in its own interest, at the expense of the individual, this
dogma becomes suicidal.

As for "reducing humanity to the level of the barn-yard," this is merely
a catch-phrase intended to arouse prejudice and to obscure the facts.
The reader may judge for himself whether the eugenic program will
degrade mankind to the level of the brutes, or whether it will ennoble
it, beautify it, and increase its happiness.

The delusion which so many people hold, that it is impossible to put
artificial restraint on the relations between the sexes, is amazing.
Restraint is already a _fait accompli_. Every civilized nation already
puts restrictions on numerous classes of people, as has been
noted--minors, criminals, and the insane, for example. Even though this
restriction is usually based on legal, rather than biological grounds,
it is nevertheless a restriction, and sets a precedent for further
restrictions, if any precedent were needed.

FIG. 29.--A common type of feeble-mindedness is accompanied by
a face called Mongoloid, because of a certain resemblance to that of
some of the Mongolian races as will be noted above. The mother at the
left and the father were normal. This type seems not to be inherited,
but due to some other influence,--Goddar
