Francisco Suárez (1548–1617), one of the most important early modern scholastic philosophers, had considerable influence not only on canonical early modern philosophers such as Descartes and Leibniz, but even more so on subsequent scholastic philosophers and theologians. His Metaphysical Disputations of 1597 was intended to provide the reader with a complete grounding in metaphysics and is one of the most detailed, comprehensive elaborations of an Aristotelian metaphysics ever published. This Critical Guide offers fourteen new essays on a wide range of topics in the Metaphysical Disputations, including Suárez's metaphysics of modality, his nominalism, and his accounts of the categories, prime matter, falsity, time, and causation. The volume will be valuable for scholars and students of early modern scholasticism, and also for those researching later thinkers whose work was influenced by Suárez.
