Sanger embraced Malthusian eugenics. Thomas Robert Malthus, a 19th-century cleric and professor of political economy, believed a population time bomb threatened the existence of the human race. His theories of population growth and economic stability became the basis for national and international social policy. Grant quotes from Malthus' magnum opus, An Essay on the Principle of Population, published in six editions from 1798 to 1826:
All children born, beyond what would be required to keep up the population to a desired level, must necessarily perish, unless room is made for them by the deaths of grown persons. We should facilitate, instead of foolishly and vainly endeavoring to impede, the operations of nature in producing this mortality.
...Sanger built the work of the ABCL,and, ultimately, Planned Parenthood, on the ideas and resources of the eugenics movement.
