Spanish American Enlightenment Ideas of the European Age of Enlightenment and the Spanish Enlightenment, which emphasized reason, science, practicality, clarity rather than obscurantism, and secularism were transmitted from France in the eighteenth century, following the establishment of the Bourbon monarchy in Spain. In Spanish America, the ideas of the Enlightenment affected educated elites in major urban centers, especially Mexico City, Lima, and Guatemala, where there were universities founded in the sixteenth and seventeenth centuries. In these centers of learning American-born Spanish intellectuals were already participants in intellectual and scientific discourse, with Spanish American universities increasingly anti-scholastic and opposed to “untested authority” even before the Spanish Bourbons came to power. The best studied is the University of San Carlos Guatemala, founded in 1676.
In Spanish America just as in Spain, the Enlightenment had some aspects of anticlericalism, but many priests were in favor of science and scientific thinking and were practitioners themselves. Some clergy were proponents of the Enlightenment as well as independence. Enlightenment texts circulating in Spanish America have been linked to the intellectual underpinnings of Spanish American independence. Works by Enlightenment philosophers were owned and read in Spanish America, despite restrictions on the book trade and their inclusion on the Inquisition’s list of forbidden books . The Jesuits were instrumental introducing new trends in philosophy to Spanish America, and following their expulsion in 1767, the Franciscans continued exploring this line of thought. Spanish American secular clergy owned such works, including Mexican priest Miguel Hidalgo y Costilla, whose free-thinking lost him his position as rector of the seminary of San Nicolás and he was sent to the small parish of Dolores.
Priests pursued science, even in the seventeenth-century “baroque” era, most prominently Mexican creole intellectual Don Carlos de Sigüenza y Góngora, as well as the remarkable Mexican nun, Sor Juana Inés de la Cruz. In the eighteenth century, there were several Spanish-born as well as American-born priests practicing science. Prominent among them was Spanish-born José Celestino Mutis in New Granada, who headed the royal botanical expedition to New Granada. He was educated in mathematics, astronomy, and medicine. Mutis trained Francisco José de Caldas. In Peru, Hipólito Unanue, a secular cleric trained in medicine, contributed to a Peruvian publication, Mercurio Peruano. Similar to him was Mexican secular cleric José Antonio de Alzate y Ramírez, who founded important newspapers that disseminated knowledge about scientific findings, including his own. Alexander von Humboldt met and consulted with Mutis, Caldas, and read the works of Alzate (who died just before Humboldt arrived in New Spain) during his scientific expedition to Spanish America at the beginning of the nineteenth century. Humboldt was impressed by the intellectual level of science in Spanish America.
