Man must remake himself.

French-American surgeon Alexis Carrel was the winner of the 1912 Nobel Prize in medicine, for his pioneer transplant work at the University of Chicago and with the Rockefeller Institute for Medical Research.
“Man, the Unknown” was reprinted in America fifty times after the first publication, and was translated into eighteen languages.

“The science of man will be the task for the future. Man must now turn his attention to himself. The development of the science of man, even more than that of the other sciences, depends on immense intellectual effort. We must realize clearly that the science of man is the most difficult of all sciences. Science, which has transformed the material world, gives man the power of transforming himself. To progress again, man must remake himself.”

Alexis Carrel ( 1873 – 1944) was a French surgeon and biologist who was awarded the Nobel Prize in Physiology or Medicine in 1912 for pioneering vascular suturing techniques. He invented the first perfusion pump with Charles A. Lindbergh opening the way to organ transplantation. He is also known for making famous a miraculous healing at Lourdes by witnessing the event Like many intellectuals before World War II he promoted eugenics.
Eugenics is the "applied science or the bio-social movement which advocates the use of practices aimed at improving the genetic composition of a population", usually referring to the manipulation of human populations.
By the mid-20th century eugenics had fallen into disfavor, having become associated with "racial hygiene", human experimentation, and the extermination of "undesired" population groups.
In Canada, the eugenics movement gained support early in the 20th century as prominent physicians drew a direct link between heredity and public health. Eugenics was enforced by law in two Canadian provinces.
In 1928, the Province of Alberta, Canada, passed legislation that enabled the government to perform involuntary sterilizations on individuals classified as mentally deficient. In order to implement the Sexual Sterilization Act of Alberta in 1928, a four-person Alberta Eugenics Board was created. These four individuals were responsible for approving sterilization procedures. In 1972, the Sexual Sterilization Act was repealed, and the Eugenics Board dismantled. During the 43 years of the Eugenics Board, it approved nearly 5,000 individual sterilizations, and 2,832 procedures were actually performed.
The campaign to enforce this action was backed by groups such as the United Farm Women's Group, including key member Emily Murphy.
As in Alberta, the British Columbia Eugenics Board could recommend the sterilization of those it considered to be suffering from "mental disease or mental deficiency".

Eugenics in Canada

Emily Murphy (born Emily Gowan Ferguson; 1868 –1933) was a Canadian women's rights activist, jurist, and author. In 1916, she became the first woman magistrate in Canada, and in the British Empire. She is best known for her contributions to Canadian feminism, specifically to the question of whether women were "persons" under Canadian law.
During the early twentieth century, scientific knowledge emerged in the forefront of social importance. Advances in science and technology were thought to hold answers to current and future social problems. Murphy was among those who thought that the problems that were plaguing their society, such as alcoholism, drug abuse and crime were caused because of mental deficiencies. In a 1932 article titled “ Overpopulation and Birth Control”, she states: "... over-population [is a] basic problem of all…none of our troubles can even be allayed until this is remedied."
Her argument was that: if there was population control, people would not need as much land. Without the constant need for more land, war would cease to exist. Her solution to these social issues was eugenics. Selective breeding was considered a progressive scientific and social approach and Murphy supported the compulsory sterilization of those individuals who were considered mentally deficient. She believed that the mentally and socially inferior reproduced more than the “human thoroughbreds” and appealed to the Alberta Legislative Assembly for eugenic sterilization. In a petition, she wrote that mentally defective children were, “a menace to society and an enormous cost to the state…science is proving that mental defectiveness is a transmittable hereditary condition.”
She wrote to Minister of Agriculture and Health, George Hoadley that two female “feeble-minded” mental patients already bred several offspring. She called it: “a neglect amounting to a crime to permit these two women to go on bearing children. They are both young women and likely to have numerous offspring before leaving the hospital”. Due in part to her heavy advocacy of compulsory sterilization, thousands of Albertans, who were not considered to possess any intelligence, were unknowingly sterilized under the Sexual Sterilization Act of Alberta before its repeal in 1972.
