Retórica científica de Andrés Bello: Hacia una “nacionalización” de la ciencia en su cosmografía de 1848

In this paper we analyze the rhetoric of Andrés Bello’s astronomical work, particularly his last publication on the subject, namely, Cosmography (1948). We suggest that the author adds to the model sustained by Humboldt and his followers the validation and promotion of what is local and national. This means that, despite the generalized trend trying to establish bonds and universalize the science, Bello insists on rooting it to America through a particular use of the language, examples and other resources that are familiar to South American, especially the Chilean people. We also reflect on the ideas that might have influenced and led him to develop his rhetoric, the most relevant among them being the emancipation impetus, the willing of progress and his relationship with the romantic literature.
