Good varieties of seed, fertile land, adequate nourishment, light, air and water are all essential for good reproduction in both the plant and animal kingdoms. In this respect human beings are no different from other creatures. In human society the selection of suitable males and females is desirable for reproduction of a high order. Until human beings are produced in scientific laboratories it will be detrimental to society if this matter is neglected.

If people of sublime intelligence and brilliance reproduce more offspring, it will be very beneficial for society. The responsibility for nurturing and bringing up these children will have to be taken by society or the government. Similarly, it will be harmful for society if mentally deficient, naturally delinquent or insane persons produce many children. In fact, society will be benefited by the permanent destruction of their reproductive capacity, providing this does not cause any harmful reaction.
