This chapter proposes primarily to consider how eugenics can be linked
with religion, and specifically the Christian religion; but the problem
is not a simple one, because Christianity is made of diverse elements.
Not only has it undergone some change during the last 1900 years, but it
was founded upon Judaism, which itself involved diverse elements. We
shall undertake to show that eugenics fits in well with Christianity;
but it must fit in with different elements in different ways.

We can distinguish four phases of religion:

1. Charm and taboo, or reward and punishment in the present life. The
believer in these processes thinks that certain acts possess particular
efficacies beyond those evident to his observation and reason; and that
peculiar malignities are to be expected as the consequence of certain
other acts. Perhaps no one in the memory of the tribe has ever tested
one of these acts to find whether the expected result would appear; it
is held as a matter of religious belief that the result would appear,
and the act is therefore avoided.

2. Reward and punishment in a future life after death. Whereas the first
system was supposed to bring immediate reward and punishment as the
result of certain acts, this second system postpones the result to an
after-life. There is in nature a system of reward and punishment which
everyone must have observed because it is part of the universal sequence
of cause and effect; but these two phases of religion carry the idea
still farther; they postulate rewards and punishments of a supernatural
character, over and above those which naturally occur. It is important
to note that in neither of these systems is God essentially involved.
They are in reality independent of the idea of God, since that is called
"luck" in some cases which in others is called the favor or wrath of
God. And again in some cases, one may be damned by a human curse,
although in others this curse of damnation is reserved for divine power.

3. Theistic religion. In essence this consists of the satisfaction
derived from doing that which pleases God, or "getting into harmony with
the underlying plan of the universe," as some put it. It is idealistic
and somewhat mystic. It should be distinguished from the idea of doing
or believing certain things to insure s
