This state of things I regard as absolutely detestable. I look upon you,
my dear sisters, as poor victims, and if you will permit I will give you
my opinion on the subject.

Esteem and friendship between husband and wife are like our daily bread,
very pleasant and respectable; but a little jam would not spoil that, you
will admit! If, therefore, one of your friends complains of the freedom
that reigns in this little book, let her talk on and be sure beforehand
that this friend eats dry bread. We have described marriage as we think
it should be--depicting smiling spouses, delighted to be together.

Is it because love is rare as between husband and wife that it is
considered unbecoming to relate its joys? Is it regret, or envy, that
renders you fastidious on the subject, sisters? Reserve your blushes for
the pictures of that society of courtesans where love is an article of
commerce, where kisses are paid for in advance. Regard the relation of
these coarse pleasures as immodest and revolting, be indignant, scold
your brethren--I will admit that you are in the right beforehand; but for
Heaven's sake do not be offended if we undertake your defence, when we
try to render married life pleasant and attractive, and advise husbands
to love their wives, wives to love their husbands.

You must understand that there is a truly moral side to all this. To
prove that you are adorable; that there are pleasures, joys, happiness,
to be found outside the society of those young women--such is our object;
and since we are about to describe it, we venture to hope that after
reflecting for a few minutes you will consider our intentions
praiseworthy, and encourage us to persevere in them.
