The organic and constitutional tendencies of those who are born are fixed. It may take a mighty effort to correct their birthright tendencies to disease and to crime. Thousands say, as the writer of the following extract says,—“We were lamentably ignorant of the natural laws of Parentage when we married. Would that light had come to us sooner. But we will not allow the happiness of our children, and our children’s children, to be wrecked for want of knowledge.” The following is the testimony of a true and earnest woman, and loving and happy wife and mother:— “Before your visit to this place to lecture on ‘The Ante-Natal History of the Human Being, and its influence on his Post-Natal Character and Destiny, in the body and out of it,’ my husband and myself had talked over the subject of Marriage and Parentage a great deal; but we never had had it presented to our minds in so strong and clear a light before. “When I was married, I was most lamentably ignorant of the laws of my nature, especially of those designed to govern Maternity. But my husband, in regard to maternity, and the relation that leads to it, is a most kind and considerate man, and I love and honor him all the more for it. I wish your book on ‘Marriage and Parentage’ had fallen into our hands before our children were born; we might have given them more loving hearts, and nobler natures, in body and soul, by understanding better how surrounding influences affect us before birth. But I am thankful for my sake, and for my children’s sake, and for the sake of the mothers that are to come after us, that your views are being so widely made known through your writings and your lectures. If mothers better understand the laws of Nature designed to govern maternity, and the relation in which it originates, they will be more careful of themselves, for sake of their children. “I have heard many mothers express their thankfulness for your visit and your conversations and lectures here. You have given hope and gladness to many anxious and despairing hearts. The mother of six little ones, and who is about to add another to the number, said to me, ‘Such instruction is exactly what men and women need.’ I felt sorry for her; yet not so sorry for her as for the unborn babe; for I know its existence is most unwelcome to the mother.
