Eugenics: what it is, history, essence and modernity

The term “eugenics” is most often associated today with the dark pages of 20th-century history, but the concept was originally conceived as a scientific method for improving the human race. Eugenics is a system of knowledge and practical measures aimed at improving the hereditary qualities of a person. At the beginning of the 20th century, this teaching seemed to many advanced scientists to be a logical continuation of Darwinism, capable of saving humanity from diseases and social vices.

However, the path from Francis Galton's theory to the laboratories of Auschwitz turned out to be frighteningly short. Eugenic ideas formed the basis of forced sterilization laws in dozens of countries and became the basis for the racial cleansing of Nazi Germany. Today, when science has made great strides forward, the question is: what is eugenics, becomes relevant again, but in the context of genetic engineering and embryo editing.

In this material we will analyze the historical roots of the doctrine, its difference from modern genetics and the ethical dilemmas that humanity faces when trying to intervene in the evolutionary process. Understanding these processes is necessary for a conscious attitude towards the achievements of biotechnology.

Origin of the term and idea of Francis Galton

An English scientist is considered the founder of eugenics Francis Galton, cousin of Charles Darwin. It was he who coined the term “eugenics” in 1883, derived from the Greek words “eu” (good) and “genos” (genus). Galton was convinced that human mental and physical abilities are inherited in the same way as external characteristics in animals.

The idea was that society should encourage the reproduction of people with “good” hereditary traits and limit the reproduction of those with “bad” genes. Galton believed that human race degrades because social institutions allow those who would not be able to do so to survive and pass on genes.

⚠️ Attention: Galton's initial ideas were theoretical in nature, but quickly grew into political programs that ignored the complexity of the human psyche and the influence of the environment.

At the dawn of its development, the teaching was not divided into rigid categories, but later researchers divided it into two main directions, each of which offered its own path to an “ideal society.”

Positive and negative eugenics: what is the difference

Historically, eugenics has been divided into positive and negative. Positive eugenics focused on stimulating the birth of children in people with desirable characteristics: high intelligence, good health, talents. Methods included financial subsidies, tax breaks, and public recognition for large families from “affluent” backgrounds.

In contrast to this, negative eugenics was aimed at preventing the birth of children with undesirable characteristics. It was this approach that led to the most terrible consequences. Measures included forced sterilization of people with mental disorders, genetic diseases, and members of certain social groups.

The distinction between these two forms has often become blurred in practice. States that introduced eugenics programs usually began with “soft” measures of support, but quickly moved to coercion and isolation of “undesirable” elements of society.

Eugenics in the history of the 20th century: from the USA to the Third Reich

Contrary to popular belief, eugenics was not only popular in Nazi Germany. At the beginning of the 20th century, it was considered an advanced science in many countries, including the USA, Great Britain and the Scandinavian states. In the United States, laws were passed to force the sterilization of thousands of people deemed “feeble-minded” or socially maladapted.

Eugenics reached its greatest and most terrible apogee in Germany in the 1930s and 40s. The Nazis turned biological theories into state ideology. Racial hygiene became the justification for the destruction of millions of people. The T-4 program involved the killing of the disabled and mentally ill, which later developed into the Holocaust.

After the revelations of the crimes of Nazism, the term “eugenics” became taboo in the scientific community. Many programs were curtailed, and the scientists themselves tried to distance themselves from their past.

Critique of Science: Eugenics vs. Genetics

It is important to clearly distinguish between eugenics as a social theory and genetics as a natural science. Genetics studies the mechanisms of transmission of traits and the laws of heredity, based on empirical data. Eugenics it is an ideology that often distorts scientific facts in order to achieve social goals.

One of the main mistakes of classical eugenics was a simplified understanding of heredity. Eugenicists believed that complex social phenomena such as poverty, crime, or low intelligence were determined solely by genes. Modern science has proven that phenotype (external manifestations) is formed under the influence of the complex interaction of genetics and environment.

Modern genetics shows that most human qualities are polygenic (depending on many genes) and are highly dependent on living conditions. The attempt to “cure” society through selective breeding is biologically unfounded.

Modern eugenics: bioethics and genetic engineering

In the 21st century, the debate about eugenics has been revived with renewed vigor thanks to the development of technology CRISPR-Cas9 and other genome editing methods. There is a real opportunity to correct genetic errors in embryos, preventing severe hereditary diseases.

However, the fine line between treatment and enhancement is hotly debated. If we can remove the gene for Huntington's disease, why not increase intelligence or physical endurance? This direction is often called liberal eugenics, where the choice is made by parents, not by the state.

⚠️ Warning: The availability of expensive genetic modifications can lead to the stratification of society into genetically enhanced and ordinary people, creating a new form of inequality.

Scientists and bioethicists urge caution. Uncontrolled interference with the human genome can have unpredictable consequences for future generations, including the emergence of new mutations or a decrease in the genetic diversity of the species.

Ethical issues and risks of genome interference

The main ethical issue is the right of a person to dispose of the heredity of his descendants. Who has the right to decide which signs are “good” and which are “bad”? History has shown that such definitions are often discriminatory and change depending on the political situation.

Another problem is the pressure on parents. If technology to prevent the disease becomes available but expensive, society may begin to condemn those who give birth to children with genetic defects, considering it their personal responsibility. This creates a toxic environment for people with disabilities.

It is necessary to develop international legal standards that will allow the use of genetics to save lives, but prohibit the creation of “designer babies” and discrimination.
