Abstract
Francisco Suarez was a Spanish Jesuit scholastic who wrote extensively on theology, metaphysics, law, and politics at the turn of the 17th century. Highly regarded, he has remained influential until the present. This paper will focus on his theories of popular sovereignty and resistance that were so implicitly influential during the early modern period and into the Enlightenment. The clear evolution from the political thinking of Plato through the Aristotelian-Thomistic school is shown to evolve into Suarez’s as a result of two factors: the universalization of natural law, and the greater emphasis placed on the individual as an independent subject. These two factors combined to subrogate the concession of authority to the people, now considered sovereign as a political body. This understanding enabled to Suarez develop a coherent resistance theory, showing in an objective non-sectarian way that political stability and legitimacy could be maintained if the deposition of a tyrannical monarch proved necessary.
