fundamentally on sound reasoning from facts of biology.

The great value of religion in this connection is that it provides a
driving power,[188] a source of action, which the intellect alone can
rarely furnish. Reason itself is usually an inhibitor of action. It is
the emotions that impel one to do things. The utilization of the
emotions in affecting conduct is by no means always a part of religion,
yet it is the essence of religion. Without abandoning the appeal to
reason, eugenists must make every effort to enlist potent emotional
forces on their side. There is none so strong and available as religion,
and the eugenist may turn to it with confidence of finding an effective
ally, if he can once gain its sanction.

The task, as this chapter was intended to show, is a complex one, yet we
see no insuperable obstacles to it. Eugenics may not become a part of
the Christian religion, as a whole, until scientific education is much
more widespread than at present, but it is not too soon to make a start,
by identifying the interests of the two wherever such identification is
justified and profitable.

We have endeavored to point out that as a race rises, and instinct
becomes less important in guiding the conduct of its members, religion
has often put a restraint on reason, guiding the individual in racially
profitable paths. What is to happen when religion gives way? Unbridled
selfishness too often takes the reins, and the interests of the species
are disregarded. Religion, therefore, appears to be a necessity for the
perpetuation of any race. It is essential to racial welfare that the
national religion should be of such a character as to appeal to the
emotions effectively and yet conciliate the reason. We believe that the
religion of the future is likely to acquire this character, in
proportion as it adheres to eugenics. There is no room in the civilized
world now for a dysgenic religion. Science will progress. The idea of
evolution will be more firmly grasped. Religion itself evolves, and any
religion which does not embrace eugenics will embrace death.

CHAPTER XX

EUGENICS AND EUTHENICS

Emphasis has been given, in several of the foregoing chapters, to the
desirability of inheriting a good constitution and a high degree of
vigor and disease-resistance. It has been asserted that no measures of
hygiene and sanitation can take the place of such inheritance. It is now
desirable to ascertain the limits within wh
