 Suárez’s Disputationes metaphysicae (1597) was published in eighteen editions over a few decades in printing centers throughout Europe—not only in Catholic, but also in Protestant regions—and had an enormous influence on philosophy teaching in European universities. It is still considered to be the most complete and comprehensive presentation of prima philosophia; and it was the most important link between Scholastic metaphysics and seventeenth-century school philosophy, influencing Descartes, Leibniz, and Wolff. Although modern scholars debate the roots of the extremely complicated system of metaphysics which Suárez presents in the treatise, they seem to agree that he created a kind of synthesis of Thomist and Scotist theories. Only a very general survey of the topics discussed in Suárez’s 54 metaphysical disputations can be provided here, along with a brief mention of some of the most important approaches to their interpretation.
