Illegitimacy however greatly deprecated morally has justified itself historically. It has produced some of earth's chosen heroes. It can be condemned ethically because it so often inflicts hardship, privation and misery on the unhappy mother and the innocent child. That subsequent marriage of the parents should bring into the family records the acknowledged previous offspring is obvious common sense, but the child whose father refuses to do its mother the sometimes doubtful "honour" of marriage should be regarded in this respect as a child whose father is dead. As our records demand a name for the father, "Anon" should serve where paternity is doubtful and the real father's name should be acknowledged in every official document in every case where paternity orders are obtained. In other words illegitimacy should be abolished and, marriage or no marriage, every child should be duly entitled to every right of inheritance, etc., which the laws at present confine to the fruit of wedlock. It is not the form of marriage or its absence but the racial result with which Eugenics is concerned. Morality, religion, or the law which holds society together may have its reproach, its deprecatory warnings, and even its punishments for _parents_ who transgress its conventions, but humanity demands that no stone shall be thrown at the _child_. Eugenics is so seriously concerned with the race that it cannot accept the pretentious puerilities which so often masquerade under the title of marriage-law reforms. The mere refusal of a marriage certificate to couples who cannot pass certain medical shibboleths, while their offspring is unconsidered (except in so far as it demands immediate public assistance) seems to be a mockery of a serious subject. The marriage of the unfit is the concern of the Eugenists primarily because deception on either side may lead to terrible evil. Physical examinations and medical certificates before marriage are an urgent necessity--not as a bar to marriage but as a hindrance to deceit. Wives must know the man they are marrying. Men must be informed what kind of wife is hidden beneath the attractive dress. A danger of marriage is that a perfectly capable healthy person may unsuspectingly marry an impotent, barren or deformed consort. Love capable of conquering a wholesome physical repulsion is one thing; love, blinded by custom, delivered bound into the hands of disease is a vile thing incapable of defence. Partners for life can even now demand a certificate on the portal of marriage, but public opinion and legislation must make such certificates an essential preliminary to the marriage contract. All legal barriers to breaking an engagement on grounds of physical and mental ill-health must be swept away, and the enlightened public must be led to learn that some promises are better broken than kept. If these ante-matrimonial conditions are observed Eugenists will look with a charitable if discouraging glance at marriages of the unfit.
