Abstract
The Dominican Pedro de Ledesma was a member of the School of Salamanca, professor of Theology in the late 16th and early 17th century. Here we investigate for the first time his contribution to the «de auxiliis» controversy, in which mainly the Dominicans and the Jesuits contended about human free will and God’s influence on it. Among the various theological problems involved, this thesis examines the nature of the divine concurrence in free human action and, in particular, divine concurrence in actual efficacious grace. Ledesma focuses his contribution to this debate on the real (and not only moral) difference between sufficient and efficacious grace. Another original feature of his conception of divine concurrence and efficacious grace are the target of his attacks, since he does not only dispute the theology of the Jesuit Luis de Molina, but also that of several Dominicans, such as Juan Vicente de Astorga; likewise, he opposes Pedro de Herrera and Diego Álvarez with a less sophisticated conception of «physical premotion» than theirs. This thesis updates Ledesma’s intellectual biography and contains the most complete list of his manuscript work to date. Ledesma’s ideas are studied on the basis of three documents: first, his unpublished lectures of 1590 on divine concurrence; second, the report on Molina’s Concordia sent to the Inquisition in 1594 (a manuscript hitherto neglected, and transcribed in the Appendix); third, the book on the dispute completed in 1601 and published in 1611.
