A "bad family history" is one in which the family has clearly manifested certain undesirable physical, mental, and moral traits in a marked degree, and in a sufficient number of instances to establish a standard. Some families have a "bad family history" for inebriety; others for epilepsy; others for licentiousness; others for dishonesty--the history extending over several generations, and including a marked number of individuals in each generation. Individuals of such a family should refrain from bearing children; and if children be born to such the greatest care should be exercised by the parents in the matter of surrounding the child with the environment least calculated to "draw out" the undesirable characteristic. The child has a right to be well born, and to be protected from being brought into the world subjected to the handicap of a "bad family history." If individuals cannot endow their children with a good family history, they should refrain from bearing children--such is the Eugenic advice on the subject. The same rule applies to the question of "acquired characteristics" of the parents--especially those acquired characteristics which are especially active at or just before the time of the contemplated conception. Though the family history of both husband and wife be ever so good, it is held that if one or both of the parents have acquired undesirable and transmissible characteristics, physical, mental, or moral, then the question of bringing children into the world should be carefully considered, and conscientiously decided, after competent authorities have been consulted concerning the case. The prospective child should always be given the benefit of the doubt in such cases. To bring children into the world merely to gratify personal pleasure or pride, regardless of the welfare of the child, is something utterly unworthy of an intelligent and moral human being. Fitness for Parenthood. In determining the "fitness" for parenthood, on the part of husband and wife, the mental, physical, and moral qualities should all be taken into consideration. Weak or abnormal mentality; chronic immorality or perverted moral sense; or diseased or abnormal physical conditions--these should always be regarded as bars to parenthood. To violate this principle is to deliberately violate the fundamental laws of Nature, as well as those principles which are accepted as representing the best thought and customs of the race. A mental, moral, or physical "pervert" or "defective" is manifestly an "unfit," considered as a prospective parent. Parenthood on the part of such individuals is not only a crime against society, but always a base injustice perpetrated upon the offspring.
