The thought and work of the Jesuit Francisco Suárez (1548-1617) is widely acknowledged as the culmination point of the contribution of the theologians and jurists of the so-called School of Salamanca to the development of modern Western law. This collection of studies on the legal work of Suárez explores some of his major forays into the law. Both his theoretical system-building as well as his interventions in practical questions are covered. Next to discussions on the nature of law and its different categorisations, they extend to various subbranches of the law including family law, property law, the law of obligations, criminal law and international law. Contributors are: Dominique Bauer, Daniel Schwartz, João Manuel Azevedo Alexandrino Fernandes, Lisa Brunori, Wim Decock, Bart Wauters, Gaëlle Demelemestre, Jean-Paul Coujou, and Cintia Faraco.
