This is a bilingual edition of the selected peer-reviewed papers that were submitted for the International Symposium on Jesuit Studies on the thought of the Jesuit Francisco Suarez (1548-1617). The symposium was co-organized in Seville in 2018 by the Departamento de Humanidades y Filosofia at Universidad Loyola Andalucia and the Institute for Advanced Jesuit Studies at Boston College. Suarez was a theologian, philosopher and jurist who had a significant cultural impact on the development of modernity. Commemorating the four-hundredth anniversary of his death, the symposium studied the work of Suarez and other Jesuits of his time in the context of diverse traditions that came together in Europe between the late Middle Ages, the Renaissance, and early modernity.
