Finally, even more important than ability to work, even more important than ability to fight at need, is it to remember that the chief of blessings for any nation is that it shall leave its seed to inherit the land. It was the crown of blessings in Biblical times; and it is the crown of blessings now. The greatest of all curses is the curse of sterility, and the severest of all condemnations should be that visited upon wilful sterility. The first essential in any civilization is that the man and the woman shall be father and mother of healthy children, so that the race shall increase and not decrease. If this is not so, if through no fault of the society there is failure to increase, it is a great misfortune. If the failure is due to deliberate and wilful fault, then it is not merely a misfortune, it is one of those crimes of ease and self-indulgence, of shrinking from pain and effort and risk, which in the long run Nature punishes more heavily than any other. If we of the great republics, if we, the free people who claim to have emancipated ourselves from the thraldom of wrong and error, bring down on our heads the curse that comes upon the wilfully barren, then it will be an idle waste of breath to prattle of our achievements, to boast of all that we have done. No refinement of life, no delicacy of taste, no material progress, no sordid heaping up of riches, no sensuous development of art and literature, can in any way compensate for the loss of the great fundamental virtues; and of these great fundamental virtues, the greatest is the race's power to perpetuate the race. Character must show itself in the man's performance both of the duty he owes himself and of the duty he owes the State. The man's foremost duty is owed to himself and his family; and he can do this duty only by earning money, by providing what is essential to material well-being; it is only after this has been done that he can hope to build a higher superstructure on the solid material foundation; it is only after this has been done that he can help in movements for the general well-being. He must pull his own weight first, and only after this can his surplus strength be of use to the general public. It is not good to excite that bitter laughter which expresses contempt; and contempt is what we feel for the being whose enthusiasm to benefit mankind is such that he is a burden to those nearest him; who wishes to do great things for humanity in the abstract, but who cannot keep his wife in comfort or educate his children.
