20 · "The Hour of Eugenics" Rather, I pull together some of the conclusions that emerge from the history of eugenics in Latin America and use them as a springboard for some reflections on the relations between science and politics in different social and political settings. In particnlar, I examine the lessons of eugenics for what I call a "politics of scientific interpreta tion," a major theme of my book. I The New Genetics and the Beginnings of Eugenics Eugenics was hardly a new idea in 1883, despite the new name coined for it that year. In some ways the weeding out of unfit indi viduals went back to the Greeks, as British eugenists were fond of pointing out, perhaps because the association gave classical authority to the otherwise shocking notion that since not all individuals are equally endowed in nature not all should necessarily be allowed to reproduce themselves. Nevertheless, "our" eugenics, properly speaking, belongs to the late nineteenth century and to the era of modern hereditarian sci ence. The eventual enthusiasm for eugenics expressed by scientists, physicians, legal expert;, and mental hygienists must be seen as the culmination of a long process of intellectual and social transforma tion in the nineteenth century, in which human life was increasingly interpreted as being the result of natural biological laws. Early in the century, for instance, Thomas Malthus, whose works on the "laws" of the biological inevitability of human overpopulation haunted nineteenth-century political economy, remarked 'that it did not by any means seem impossible that by selective breeding "a certain de gree of improvement, similar to that amongst animals, might take place among men." He added, however, "As the human race could not be improved in this way, without condemning all the bad speci- 22 "The Hour of Eugenics" The New Genetics and Eugenics · 23 mens to celibacy. it is not probable that an attention to breed should In this book, Galton took it upon himself to prove by simple 1 ever become general.
