In his book Fundamental Outline of Racial Hygiene, Ploetz called for the elimination of "counter-selective processes." He was concerned about social processes that reversed the work of natural selection by eliminating the strong and favoring the weak. He did not like war, because it eliminates the strong. And he opposed charitable programs to protect the weak and the ill. He suggested that doctors who were present at the birth of a weak or malformed child could provide an easy death with a small dose of morphine.
In 1922, a German lawyer named Karl Binding and a German psychiatrist named Alfred Hoche published a slim book with a clumsy title: Permission to Destroy Life Not Worth Living (Die Freigabe der Vernichtung lebensunwerten Lebens). They argued in favor of euthanasia, or mercy killing. The cost of maintaining useless people was too high, and the government could spend the money on better things. Religious barriers should be pushed aside, so that the government could get on with the job of killing the physically and mentally defective (painlessly). Destroying useless lives was necessary for the survival of society as a whole, they wrote.
In 1935, a French-American Nobel Prize winner, Dr. Alexis Carrel, wrote Man the Unknown, in which he advocated building euthanasia institutions to deal with criminals and the mentally ill, using some suitable gas.
Step by step, positive eugenics gave way to negative eugenics. In 1910, Francis Galton and the President of the new Eugenics Society, Montague Crackanthorpe, gave a reception for Ploetz in London. Later, Ploetz and his colleague R¸din built the German racial hygiene program, and both were ardent supporters of Hitler.
So is the eugenics movement dead? Or is PP keeping the movement alive? Some think so.
