First published in 1917, this controversial book argued for the need to promote birth control in order to improve the quality of the human race. Drysdale's arguments were grounded in both moral and scientific principles, and he was a strong advocate for women's rights and reproductive freedom. Although some of his ideas have been discredited over time, his passionate advocacy for birth control and his engagement with the thorny ethical questions surrounding it remain relevant today.
