To begin these speculations in logical order we must begin at the birth point, we must begin by asking how much may we hope, now or at a later time, to improve the supply of that raw material which is perpetually dumped upon our hands? Can we raise, and if so, what can we do to raise the quality of the average birth? This speculation is as old at least as Plato, and as living as the seven or eight babies born into the English-speaking world since the reader began this Paper. The conclusion that if we could prevent or discourage the inferior sorts of people from having children, and if we could stimulate and encourage the superior sorts to increase and multiply, we should raise the general standard of the race, is so simple, so obvious, that in every age I suppose there have been voices asking in amazement, why the thing is not done? It is so usual to answer that it is not done on account of popular ignorance, public stupidity, religious prejudice or superstition, that I shall not apologize for giving some little space here to the suggestion that in reality it is not done for quite a different reason. We blame the popular mind overmuch. Earnest but imperfect men, with honest and reasonable but imperfect proposals for bettering the world, are all too apt to raise this bitter cry of popular stupidity, of the sheep-like quality of common men. An unjustifiable persuasion of moral and intellectual superiority is one of the last infirmities of innovating minds. We may be right, but we must be provably, demonstrably and overpoweringly right before we are justified in calling the dissentient a fool. I am one of those who believe firmly in the invincible nature of truth, but a truth that is badly put is not a truth, but an infertile hybrid lie. Before we men of the study blame the general body of people for remaining unaffected by reforming proposals of an almost obvious advantage, it would be well if we were to change our standpoint and examine our machinery at the point of application. A rock-drilling machine may be excellently invented and in the most perfect order except for a want of hardness in the drill, and yet there will remain an unpierced rock as obdurate as the general public to so many of our innovations.
