Eugenics as a direction of scientific thought and practice of human selection in the late 19th — early 21st centuries

Introduction. The article raises the problem of eugenics as a direction of scientific thought and practice of improving the human species. The modern advances in reproductive medicine, the development of biology, the emergence of methods for editing the human genome have updated the debate around eugenics. The aim of the work is a comprehensive study of the discourse and practice of eugenics in the period of the 19th — 21st centuries. This aim involves solving a number of tasks: 1) analysis of the historical context and prerequisites for the eugenics emergence; 2) the study of the institutionalization and practical implementation of its ideas in Western countries in the period until the end of World War II; 3) research on the position of eugenics after the war and the transition of discussions to the mainstream of genetics, bioethics, transhumanism; 4) study of the modern discourse of eugenics, ethical issues and the degree of government intervention in population reproduction. Methods. The author uses the historical-retrospective method, which makes it possible to comprehensively consider the context of the emergence and development of eugenics, the comparative method (when comparing the characteristic features of the «old» (authoritarian, forced) and «new» (democratic, based on personal choice) eugenics), the institutional approach ( when identifying the main institutions involved in the development, dissemination, implementation of the ideas of eugenics) and a discursive approach (to study modern discussions about the «new» eugenics and related ethical problems). Scientific novelty of the research. A comprehensive study of eugenics has been carried out, a connection has been established between the «old» and «new» eugenics, and their similarities and differences have been investigated. Results. The need to distinguish eugenics as a theory of human selection and as a practice has been proven, and the latter, depending on the political, cultural and socio-economic situation in the country, can take a variety of forms: from counseling and preventive measures to racial cleansing. It was found that population growth, urbanization, mass migration, instability in society, combined with the ideas of modernism about social order by the forces of science and technology, contributed to the spread of eugenics ideas in the late 19th - early 20th centuries. After the Nuremberg trials, the concept under study temporarily dropped out of scientific discourse. The article examines in detail the socio-economic and other preconditions that contributed to the revival of interest in eugenics in the 60s of XX century and at the present stage. It is shown that today part of the discussion has shifted to the mainstream of genetics, bioethics and transhumanism. Conclusions. It has been established that discussions about eugenics run up against the problem of breeding control, which means that they raise the question of who should perform selection, how, what are its criteria. The ethical aspects of introducing control are complicated by the fact that perceptions of the «norm» and the degree of permitted interference depend on the particular society.
