At the end of the 19 th century, Georges Vacher de Lapouge and Otto Ammon founded a school of thought denominated "social anthropology" or "anthropo-sociology," aimed at placing racism on a scientific basis. Their intent was to create a new discipline into which the themes of biological heredity, natural selection, social stratification, and political organization were to converge. This paper intends to demonstrate the wide resonance that anthroposociology had in the economic literature, analyzing the thought of authors such as Carlos C. Closson, Vilfredo Pareto, and Thorstein Veblen. A particular focus will be on the racial and eugenic arguments used as explanation of social and economic inequality.Social anthropology is today considered a flourishing branch of human knowledge, promoted all over the world by specialist journals and scientific institutions. 1 However, the social anthropology dealt with in these pages has little to do with this reality. At present his research activity mainly deals with the problem of inequality and, in particular, the "Pareto law." He would like to thank the anonymous readers of AJES and Laurence Moss for their helpful comments. He is extremely grateful to Francesco Asso, Fabrizio Bientinesi, Luca Fiorito, and Tiziana Foresti for their bibliographical support. None of them are, of course, responsible for any errors.
