Concerning that part of this question which deals with the restriction of birth, it has always seemed that outside of voluntary childless marriages the importance of "race suicide" was over-estimated. Where there is no pathological reason why children should not be born, there can be no question but that voluntary childless marriage is what has been well termed "a progressive substitute for prostitution." But where not used to consummate this end, but to keep within the limits of the proper education and the bringing up of the progeny of a human pair, such practice as does not involve infanticide cannot be against the best interests of the race. Consequently, it would seem that, before marriage, young men and women should become acquainted with the fundamental phenomena of conception, with the purpose in view of regulating the number of children which they bring into the world to such a number as they can properly educate and equip for the struggle of existence. Such biological knowledge as is necessary to attain this should become the common property of humanity, and the state should not restrict the sale of such articles as would further this end. On the other hand, young men and women should be taught that it is their duty to have what children they can care for, and at such times and under such conditions during wedlock as will insure their descendants the best physical and mental equipment. Infanticide in any form and at any time, except when performed under the jurisdiction of a reputable physician, should be made a crime and proper punishment provided therefor. In this phase of the question, there is also a place for the fostering of proper sentiment. Parents should show their children that they constitute a very large proportion of their happiness, and that child-bearing, within the limits above set forth, is a privilege and not a burden. Under these conditions, voluntary childless marriage will become less frequent and the family will occupy the position of primary importance in the state to which it is entitled.
