Francisco Suárez (1548–1617) was one of the most important philosophers and theologians of early modern Aristotelian scholasticism. Although Suárez spent most of his academic career as a professor of theology, he is better known today for his Metaphysical Disputations (Salamanca, 1597). The present volume contains a facing-page English translation of Metaphysical Disputation II, which is devoted to the nature of real being, the subject of metaphysics. In it, Suárez is especially concerned, first, to argue there is a single nature of being common to all real beings, and second, to show what this nature consists in. The Latin text contained in this volume introduces a significant number of corrections to the text of the Vivès edition, the one standardly used by scholars of Suárez, and thus more faithfully reproduces the text of the first edition. The volume also contains a lengthy introduction that provides a detailed survey of the disputation's principal claims and arguments.
