Marriages of individuals whose families are marked by minor taints can not justify social interference; but an enlightened conscience and a eugenic point of view should lead every individual to make as good a choice as possible.
If a eugenically bad mating has been made, society should minimize as far as possible the injurious results, by means of provision for properly restricted divorce.
Consanguineous marriages in a degree no closer than that of first cousins, are neither to be condemned nor praised indiscriminately. Their desirability depends on the ancestry of the two persons involved; each case should therefore be treated on its own merits.
