Finally, the eugenic program calls for the spread of the facts, far and wide, through all classes of society. Bring forcibly before the people the facts of human heredity. Teach them to understand the force of the eugenic ideal of good breeding. "The prevalent opinion that almost anybody is good enough to marry is chiefly due to the fact that in this case, cause and effect, marriage and the feebleness of offspring, are so distant from each other that the near-sighted eye does not distinctly perceive the connection between them." By education we must produce first of all a thoughtfulness in the community regarding the racial responsibilities of marriage and reproduction. Human beings are frequently rational creatures; placing before them clear and truthful ideas regarding fit and unfit matings cannot fail of an ultimate effect. "The virtue of repetition, the summation of suggestion, which sells pills and pickles, which makes Free Trade or Tariff Reform a national issue, this force operating as a slight but persistent influence when linked to eugenic proposals will in a few years' time make these proposals a living force to the common man." By talking and teaching, in season and out, the community will be compelled to think on these things; they will be forced into the public conscience and the pressure of public opinion will rise for the eugenic and against the noneugenic ideals of mating and the rearing of families. And the rest will come in due season and more effective and permanent results will follow than are likely to come from any amount of premature legislation. As Galton writes: "The enlightenment of the individual is a necessary preamble to practical Eugenics, but social opinion by praise or blame constantly influences individual conduct." "Public opinion is commonly far in advance of private morality, because society as a whole keenly appreciates acts that tend to its advantage, and condemns those that do not. It applauds acts of heroism that perhaps not one of the applauders would be disposed to emulate." "The first and main point is to secure the general intellectual acceptance of Eugenics as a hopeful and most important study. Then let its principles work into the heart of the nation, who will gradually give practical effect to them in ways that we may not wholly foresee."
