This new third edition, with an entirely new format, has been thoroughly edited with careful consideration of the well deserved criticisms I have received from my readers. Part One presents a very general overview of Margaret Sanger's strange philosophies. Like Hitler's Germany, a country she had some association with, she wanted nothing more than to breed a super race, a race of "thoroughbreds" as she called them. She would accomplish her vision by means of abortion, euthanasia, and genocidal sterilization carried out against minority groups. These were her primary instruments to accomplish her purpose. Part Two illustrates how Sanger would implement her speculations concerning a human sexual reformation and explains how she would convert her strange theories into the general behavior of society. Part Three discusses the objections often raised against my basic assumption that there is no such thing as an "inferior race." Part Four describes Margaret Sanger's degeneration and death and indicates the probable similarities between her end and the end of our contemporary world. In Part Five Sanger's human rights philosophy is contrasted with that of her most notable enemy; and it is shown how Margaret Sanger, by the most skillful use of propaganda the 20th century has yet seen, convinced the world of her "liberalism" - even though she was, in fact, opposed to many basic human liberties because she considered common people to be a threat to the well being of the planet.
