The Enlightenment is commonly held accountable for the rise of both racial classification and modern scientific racism. Yet this argument sits uneasily alongside the birth of a modern rights language and strong anticolonial perspectives within the same intellectual movement. This article seeks to make sense of this paradox by arguing that one of the contexts in which we can best understand eighteenth-century race concepts is humanity’s place in a transformed history of nature that brought together novel understandings of deep time (...) and a materialist view of reproduction. Analysing the thought of Georges-Louis Leclerc, Comte de Buffon and Denis Diderot, the article demonstrates that the waning of both the authority of biblical genealogies and ancient environmentalist explanations of human physical diversity left a lacuna in the eighteenth-century human sciences. Buffon and Diderot’s “races” of humanity are not fixed entities, but rather exist in the flux of time. New understandings of heredity and reproduction combined with a time revolution led these Enlightenment thinkers to reconceive humanity’s place in the natural world. The article suggests that while “race” is a biologically incoherent concept, two elements of these Enlightenment thinkers’ anthropology – a materialist understanding of reproduction and humanity’s place in deep time – remain central to how we understand human diversity.

This article critically examines the different ways in which American Enlightenment thinkers confronted the future of being white in the early republic as political economists, natural historians, physicians, and anatomists of the mind. Just as philosophes experimented on the nature of blackness in Bordeaux's Royal Academy of Sciences, the American Philosophical Society supported novel approaches to the racial classification of whiteness. An appeal to Scottish Enlightenment racial theories connected the diverging thought of Benjamin Franklin, Thomas Jefferson, Samuel Stanhope Smith, and (...) Benjamin Rush as prominent members of this society between 1743 and 1826. In doing so, Franklin industrialised the political economy of a ‘purely white’ nation. Jefferson naturalised the language of whiteness. Smith universalised the intellectual and moral cultivation of whiteness. And Rush medicalised an architype of a healthy mind and body as white. This article argues that Scottish philosophy informed radically different ideas about how to become white in the early American republic. (shrink)

Franco Andrea Bonelli, a disciple of Lamarck, was one of the few naturalists who taught and disseminated transformism in Italy in the early nineteenth century. The explanation of the history of life on Earth offered by Lamarck’s theory was at odds with the Genesis narrative, while the issue of man’s place in nature raised heated debates. Bonelli sought to reconcile science and religion through his original interpretation of the variability of species, but he also focused on anthropological subjects. Following Blumenbach’s (...) studies, he investigated the differences within the human species and explored the topic of humans’ alleged superiority over animals. The origin of human beings, their history, and their relationship with the rest of life were thus read in light of transformism. According to Bonelli, such questions would not do irreparable damage to the new theory. On the contrary, he considered evolution not only acceptable but even necessary to protect the Holy Texts from certain dangerous trends in anthropological and zoological research. (shrink)
