Most studies of René Descartes’s legacy have focused on the novelty of his ideas, but little has been done to uncover the conditions that allowed these ideas to spread. Seventeenth-century Europe was already a small world—it presented a high degree of connectedness with a few brokers bridging otherwise disparate regions. A communication network known as the Republic of Letters enabled scholars to trade ideas—including Descartes’s—by means of correspondence. This article offers an analysis—both qualitative and quantitative—of a corpus of letters written (...) during Descartes’s lifetime and mentioning his name. The aim is to unveil the factors that drove the diffusion of Descartes’s ideas. The results are twofold. First, a close reading of the letters reveals that they were not used to create awareness about Descartes and his works but rather to discuss his ideas. Second, a network analysis of the letters shows that ideas do not spread like viruses, thus undermining the ‘social contagion’ model, and that weak ties are not as effective in promoting innovations as they are in circulating information.

Summary This paper explores the collecting practices of German Protestant missionaries who lived in southern India (c. 1710–1740) as part of the Danish-Halle mission. Asked by their patrons to describe local plants, in situ, these individuals did not respond by carefully studying and describing the plants themselves. Despite being in a position to do this work, instead they chose mostly to engage local residents in conversations about the cultures of the plants in question. These conversations revolved around the origins and (...) meanings of plant names. The missionaries used names, local histories and accounts of peoples as tools for understanding plants found in specific places and to resolve confusion over the similarities and differences between various kinds. They practiced a form of ethno-botany that made the culture(s) of plants accessible to those who would never be able to actually travel to the region. (shrink)

ArgumentBy the year 1720, one could visit at least three large-scale wooden models of Solomon's Temple in the cities of Amsterdam, Hamburg, and Halle. For short periods of time, the Amsterdam and Hamburg Temple models were exhibited in London, where they attracted a great deal of attention. The Halle model, on the other hand, never moved from its original location: a complex of schools known today as the Francke Foundations (die Franckesche Stiftungen). This article explores the reasons for the Halle (...) model's striking immobility by considering its position at the center of a long-distance network, also referred to as the Danish-Halle mission. In this article I argue that the Halle Temple model functioned as an effigy and memory theater that helped proponents of this mission make a case for the Temple's status as the world's first information technology. Young people moved around the wooden model; they took virtual pilgrimages with it and internalized its infrastructure by memorizing its various components. The model's position at the center of the complex's striking ethnographical collection and curricula exposes relations between the Danish-Halle mission, Christian philosophy, and an irenical turn as public policy in early eighteenth-century Brandenburg-Prussia.

ArgumentThe eighteenth-century natural histories ofParaquaria, a Jesuit province in South America ranging from the tropical forest to Río de la Plata (the River Plate), constitute a rich and consistent tradition of nature writing. The way the material is organized, the frequent use of lists of aboriginal names, and the focus on naming, all attest to the missionaries' preoccupation with language, understandable given that they were engaged in writing dictionaries and thesauri of the native tongues. During the nineteenth and twentieth centuries, (...) this body of work went through a series of appropriations, reflecting the various intellectual programs that contributed to the making of the national tradition in Argentina. While these natural histories are still often interpreted in terms of Argentina's national history, science, and literature, I will argue that they should be considered a product of a mixed culture oriented toward the practical and religious goals that are characteristic of most of Jesuit missionary culture, the result of the missionaries' attempt at organizing their experience of the wilderness and their encounter with the aboriginal peoples.

This article is based on a perspective on circulation of knowledge that allows the consideration of science as the result of the encounter between diverse communities. We tell a story that constantly changes places, scales, and cultures in order to stress the importance of networks as an alternative to the centre/periphery trope, which entangles world histories of science. The result is a picture much more complex and intertwined than the one suggested by these simplifying dichotomies. We focus on a case (...) study that illuminates the process of knowledge production in non-European spaces of modernity. The return of the Society of Jesus to the newly independent nation-states of Latin America is the point of departure to analyse the circulation of a specific scientific idea in Ecuador: Darwin’s theory of biological evolution through natural selection. The article follows the paths of three different knowledge makers whose encounters are seen as sites of knowledge production: a religious order, a Latin American... (shrink)

During the century of colonial expansion by the Iberian monarchies, the presence of the Church alongside the colonizers was not just a logical continuation of the medieval idea of the good prince who was advised and accompanied by men of faith. It also underlined the political dimension of the ‘spiritual conquest’ and the equally political dimension of the cultural practices accompanying it. There are numerous works that have emphasized this with regard to the American continents in particular, where the connection (...) between the forces present, which quickly led to the destruction and subjugation of the local populations, brought about Spanish colonial domination over large swathes of the ‘West Indies’. Those scholars who have concentrated on the ‘East Indies’, and China in particular, have emphasized acculturation or accommodation, highlighting the cultural rather than the political dimension of contact. This article explores the significant asymmetries in the understanding of humankind developed by the missionaries in their analyses of the Americas and the East Indies. These asymmetries stemmed largely from their distinct roles and functions in the process of colonial or imperial contact. I argue that these asymmetries obscure our understanding of what missionaries contributed to the global circulation of knowledge of lands and peoples new to Europeans in the 16th and 17th centuries, in part by defining ‘savagery’ and locating it mostly in the ‘West Indies’.
