 Among the main Jesuits of New Spain who were forced to leave their homeland were two prominent philosophers: Diego José Abad and Francisco Javier Clavijero. Diego José Abad taught a complete course on philosophy in which he studied modern philosophers such as Descartes and Gassendi. Abad tried to reconcile modern philosophy and Scholasticism by trying, for example, to reconcile atomism and Aristotelian hylomorphism. Francisco Javier Clavijero (1731–1787) wrote Storia antica del Messico (1780 [2006]) in which he examines pre-Columbian history using the model of Greco-Roman classical history. He also wrote a Cursus philosophicus, of which only one section has been preserved: Physica particularis (1765).
