The collection centres on eugenics, the notion that humanity can be improved and perfected by selective breeding and the elimination of individuals and groups considered to be undesirable.
It also fails to stress just how much the socialist left initiated and supported the eugenics campaign, not only in Germany but in Britain, the U. S. and the rest of Europe.
Playwright George Bernard Shaw, English social democrat leader Sydney Webb and, in Canada, Tommy Douglas were just three influential socialists who called, for example, for the mass sterilization of the handicapped.
The most vociferous and outspoken of the socialist eugenicists was the novelist H. G. Wells, author of The Time Machine, The War of the Worlds and The Invisible Man.
He argued in best-selling books such as Anticipations and A Modern Utopia that the world would collapse and from this collapse a new order should and would emerge.
In the United States socialist writer Margaret Sanger, the founder of Planned Parenthood and the mother of the abortion movement, called for a radical eugenics approach as early as the first years of the 20th century.
She wrote of the need for "a stern and rigid policy of sterilization and segregation to that grade of population whose progeny is already tainted or whose inheritance is such that objectionable traits may be transmitted to offspring. It is a vicious cycle; ignorance breeds poverty and poverty breeds ignorance.
There is only one cure for both, and that is to stop breeding these things. Stop bringing to birth children whose inheritance cannot be one of health or intelligence. Stop bringing into the world children whose parents cannot provide for them. Herein lies the key of civilization."
