same argument is used for conjugal union with prevention. In both cases the
natural result of union is not desired, and positive means are taken to
prevent it.

And what of the results on the mutual love, if an old-fashioned word be
not now out of place, and on the self-respect of two people so associated?
Birth control cannot make for happiness, because it means that mutual love
is at the mercy of an animal instinct, neither satisfied nor denied. It is
an old truth that those who seek happiness for itself never find it. And
yet the advocates of birth control have the temerity to claim that these
practices lead to happiness. I presume that of the bliss following marriage
with contraceptives the crowded lists of our divorce courts are an index.
The marriage bond is weakened when a common lasting interest in the care
of children is replaced by transient sexual excitement. Once pregnancy is
abolished there is no natural check on the sexual passions of husband or
wife, for they have learnt how sexual desire may be gratified without the
pain, publicity, and responsibility of having children. In the experience
of the world marriages based merely on passion are seldom happy, and
artificial birth control means passion uncontrolled by nature. These
methods are not practised by nations such as Ireland and Spain, who accept
the moral rule of the natural law expressed in God's commandments and
sanctioned by His judgments; and no man who has ever lived in these
countries could truthfully maintain that the people there, on whom the
burdens of marriage press as elsewhere, are in reality anxious to obtain
facilities for divorce. On the other hand, there are many who allege that
the people of England are shouting out for greater facilities for divorce
than they now possess. At any rate, it is obvious enough that there are
those amongst us who are straining every nerve to force such facilities
upon them.
