Women of this type should have their attention drawn to the following facts in this connection: While the most recent investigations of heredity prove that a woman cannot affect the potential possibilities of her child, she can seriously affect its physical vitality. The following illustration may render our meaning clear: suppose your child had the inborn qualities necessary to attain a 100 per cent. record of achievement in the struggle of life; anything you may or may not do cannot affect these qualities--the child will still have the ability to achieve 100 per cent. Inasmuch, however, as a mother can affect the health or physical qualities of her[83] child she is directly responsible, through her conduct, as to whether her child will ever attain the 100 per cent. record, or if it does, she is responsible for the character of its comfort, its health, its enjoyment, all through its life's struggle toward the 100 per cent. achievement record. She may so compromise its physical efficiency that it will succumb to disease as a consequence of the ill health with which its mother unjustly endowed it, even though it possess the ability to attain the 100 per cent. if it lived. We often see brilliant children who are nervous and physically unfit, and we see others of more ordinary mental achievement who are healthy and robust animals. The one is the offspring of parents possessing unusual mental qualities but who are physically unable or unwilling to render justice to their progeny; the other parents may be less gifted mentally, but they are healthy and they are willing to give their best in conduct and in blood to their babies. Many of these brilliant children never achieve their potential greatness because they fall by the wayside owing to physical inability, while the healthy little animals achieve a greater degree of success because of the physical vitality which carries them through. To achieve a moderate success and enjoy good health is a better eugenic ideal than the promise of a possible genius never attained because of continuous physical inefficiency. The nervous and willful mother should therefore consider how much depends upon her conduct. It cannot be too frequently reiterated and emphasized that every mother should do her utmost to guard and retain her good health. Good health means blood of the best quality and this is essential to the nourishment of the child. To keep in good health does not mean to obey in one respect and fail in other essentials. It means that you must obey every rule laid down by your physician, willingly and freely in your own interest and in the interest of your unborn babe. In no other way may you hope to creditably carry out the eugenic ideal that "the fit only shall be born."
