It seems that Charles did not find eugenics very noble and prefered that the individual be the decider of his mate. In The Descent of Man Darwin noted that aiding the weak to survive and have families could lose the benefits of natural selection, but cautioned that withholding such aid would endanger the instinct of sympathy, "the noblest part of our nature", and factors such as education could be more important. When Galton suggested that publishing research could encourage intermarriage within a "caste" of "those who are naturally gifted", Darwin foresaw practical difficulties, and thought it "the sole feasible, yet I fear utopian, plan of procedure in improving the human race", preferring to simply publicise the importance of inheritance and leave decisions to individuals.[147]
"Before eugenicists and others who are laboring for racial betterment can succeed, they must first clear the way for birth control. Like the advocates for birth control, the eugenicists, for instance, are seeking to assist the race toward the elimination of the unfit." --Margaret SangerOur own little master race!
