Eugenics 19 tain that potential parents should give more than a passing thought as to the [italics]kind of entail[end italics] they propose to pass on to future generations. 4. All of which leads to the following practical suggestions: If marriage is entered into by those notoriously unfit to give a righteous biologic entail, that state has a right to insist on sterilization. As a corollary, the knowledge of birth control should be widely and freely disseminated so that among certain groups in our civilization there may be not more but fewer and better children. And conversely, the leaders and builders of America should ponder the new statistical knowledge which demonstrates that they will only hold their own with 4.1 children per family, and gain on the population only with 4.5 children per family, and that at present they are actually losing in the race with only 2.9 children per family. He that hath ears let him hear what the statistician saith unto the churches. I once read of a biologic will of debit. It ran as follows: [extract, smaller text] To my son, John, I bequeath my chorea, my slouching gait, and my susceptibility to tuberculosis. To my son, Samuel, I bequeath my cocaine habit, my general shiftlessness, and my utter lack of all social responsibility. To my daughter, Mary, I bequeath my unhappy disposition, my mental laziness, and my lack of moral self-control. I make these bequests with the certain knowledge that this my last will and testament will never be contested, will never pay a lawyer's fee, and will be probated long before my decease. [text] The three witnesses of the will were Paternal Heredity, Maternal Heredity, and Biologic Law. It is possible to write a biologic will of credit: [extract, smaller text] In the name of God, Amen. I, William Jones, being of sound body and mind and a lover of my race, as a custodian of the racial stream, do herewith give and bequeath to my beloved son, John, a strain of blood uncontaminated by alcohol, nicotine, or other harmful drug. To my beloved son, Samuel, I give and bequeath my ability to work hard and effectively, my financial thrift, my sense of humor, and my reputation for honorable dealing. To my beloved daughter, Mary, I give and bequeath stable nerves, a sunny disposition, and reverence for everything that is sacred and beautiful. I surrender this will to the custodianship of Biologic Law, and appoint as my executor, Almighty God. [text]The three witnesses of the will were Paternal Heredity, Maternal Heredity, and Father Time. He that hath ears to hear, let him hear what eugenics saith unto the churches. [end]
