It is at this point that eugenics comes in and demands that a distinction be made between the interests of the individual and the interests of the race. It does not yield to any one in its solicitude for the individual unfortunate; but it says, "His happiness in life does not need to include leaving a family of children, inheritors of his defects, who if they were able to think might curse him for begetting them and curse society for allowing them to be born." And looking at the other side of the problem, eugenics says to the young man and young woman, "You should enjoy the greatest happiness that love can bring to a life. But something more is expected of you than a selfish, short-sighted indifference to all except yourselves in the world. When you understand the relation of the individual to the race, you will find your greatest happiness only in a marriage which will result in a family of worthy children. You are temporarily a custodian of the inheritance of the whole past; it is far more disgraceful for you to squander or ruin this heritage, or to regard it as intended solely for your individual, selfish gratification, than it would be for you to dissipate a fortune in money which you had received, or to betray any trust which had been confided to you by one of your fellow men."
Such is the teaching of eugenics. It is not wholly new. The early Greeks gave much thought to it, and with the insight which characterized them, they rightly put the emphasis on the constructive side; they sought to breed better men and women, not merely to accomplish a work of hygiene, to lessen taxes, and reduce suffering, by reducing the number of unfortunates among them. As early as the first half of the sixth century B. C. the Greek poet Theognis of Megara wrote: "We look for rams and asses and stallions of good stock, and one believes that good will come from good; yet a good man minds not to wed an evil daughter of an evil sire, if he but give her much wealth.... Wealth confounds our stock. Marvel not that the stock of our folk is tarnished, for the good is mingling with the base." A century later eugenics was discussed in some detail by Plato, who suggested that the state intervene to mate the best
