If the supreme end is a better race we must recognize that the great need for society to-day is to educate for parenthood. History teaches that a civilization that dissipates its virility in profligacy or spends its energy in political and commercial trickery, and gives no thought to the character of the men and women it produces, is destined to total failure. Parenthood and birth--in these we have the eugenic instruments of the [16] future. The only permanent way to cure the ills of the world is to prevent the multiplication of people below a certain standard. The elevation and the actual preservation of the race depends upon rendering it impossible for the unfit coming into existence at all. In other words the unfit or unworthy must be rejected, not necessarily as individuals, but as parents. Eugenics is allied to the principle of heredity,--the principle that enables us to modify conditions so as to ensure the right children being born. The propaganda against infant mortality is directed only toward the provision of a good environment,--so that children, when born, may survive and attain the maximum of their hereditary promise. The two campaigns are essentially complementary. The one applies only before birth, the other after birth. The statistics of infant mortality unfortunately show that it is not a process that extinguishes the unfit only. The healthy succumb to unfavorable environment and it was to amend this condition that the campaign against infant mortality was undertaken. The two campaigns appeal to the same creed: that parenthood is the supreme function of the race, that it must not be indifferently undertaken; that it demands the most careful preparation; that it is a duty which can only be carried out eugenically by the highest attainable health of body and mind and emotions.
