Context

“So soon as I realized that the convent was the only alternative to marrying Louis, I had, as girls say, to "submit," and my submission once made, the next thing was to examine the situation and try to make the best of it. The serious nature of what I was undertaking filled me at first with terror. Marriage is a matter concerning the whole of life, whilst love aims only at pleasure. On the other hand, marriage will remain when pleasures have vanished, and it is the source of interests far more precious than those of the man and woman entering on the alliance. Might it not therefore be that the only requisite for a happy marriage was friendship—a friendship which, for the sake of these advantages, would shut its eyes to many of the imperfections of humanity?” source
