The ideas of the Spanish Enlightenment, which emphasized reason, science, practicality, clarity rather than obscurantism, and secularism, were transmitted from France to the New World 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.[1] The best studied is the University of San Carlos Guatemala, founded in 1676.[2]
