“Men and women are not virtuous by law. Law itself does not of itself create virtue, nor is it the foundation or fountain of love. Law should protect virtue, and law should protect the wife, if she has kept her contract, and the man, if he has fulfilled his. But the death of love is the end of marriage. Love is natural. Back of all ceremony burns and will forever burn the sacred flame. There has been no time in the world's history when that torch was extinguished. In all ages, in all climes, among all people, there has been true, pure, and unselfish love.”
