=The primal purpose of marriage.=--If boys and girls were properly trained and safeguarded, if our customs and habits of life were natural instead of artificial; they would use up their sexual energy in their various activities. Under such normal conditions the gradually developing paternal and maternal instincts, which are the products of maturing sexual life, would be under perfect control and lead them to marry for the primal purpose of procreating the species and perpetuating the race. This God-implanted paternal and maternal instinct, in their relation to the normally developing sexual natures, are so strong that matured young people are willing to assume every burden connected with maintaining a home and every sacrifice incident to raising a family of children. =Maternity not an affliction.=--No normal wife, properly educated, who has the right view of marriage, looks upon maternity as an affliction. No woman, capable of normal motherhood should marry, who considers maternity a great affliction. The woman who is willing to sell the use of her body to one man in marriage for the consideration of being married, for food, clothing and shelter, and who deliberately and willfully avoids maternity, is but little better than the woman who prostitutes herself to a number of men for a price. The motives that lead a man and woman to commit prostitution outside of the bonds of marriage cannot be made sacred and pure by the sanction of law and a marriage ceremony. When husband and wife are mutually agreed, in this crime, he is as guilty as she. =Procreative periods in the sexes.=--The possible procreative period of man extends from about seventeen to the close of life. His normal procreative period extends from about twenty-four to the beginning of his change of life. The possible procreative period of woman extends from puberty to the close of the change of life. Her normal procreative period extends from about twenty to the beginning of her change of life. =Function of menstruation.=--The function of menstruation is to prepare the womb for the reception of embryonic life. Since the womb during menstruation is not prepared for the reception of this beginning life, the wife instinctively repels the sexual approaches of her husband. =Pregnancy a period of continence.=--When impregnation occurs and the womb becomes the closed home of embryonic life, sexual desire largely or entirely ceases in the normal woman. She now enters a nine-month period of gestation. Again it is natural for her to repel sexual approaches of her husband. All the pregnant females among the lower animals and savage man faithfully repel the approach of their mates during gestation. This law is violated alone by semi-civilized and civilized man. The females among the lower animals and savage men do not dread maternity and the males are normal and do not force their demands upon their mates during gestation.
