"The Pivot of Civilization" is a non-fiction book written by Margaret Sanger, the founder of the birth control movement in the United States. Sanger argues that overpopulation is the root cause of poverty, disease, and social unrest. She advocates for the use of birth control methods to enable women to control their own reproductive health and prevent unwanted pregnancies. Sanger also argues that access to birth control can help to improve the lives of women and children, and can ultimately lead to a better society. In "The Pivot of Civilization," Sanger makes a powerful case for the importance of reproductive rights and family planning. Her ideas were controversial at the time, but they helped to pave the way for the widespread availability of birth control and the legalization of abortion in the United States. Overall, "The Pivot of Civilization" is an influential book that remains relevant today as debates around reproductive rights and family planning continue to shape public policy and social attitudes.
