In Later Medieval Metaphysics: Ontology, Language, and Logic, Bolyard and Keele write:
Medieval metaphysics and modern-day metaphysics share much common ground; many issues of concern to medieval metaphysicians would be quite familiar to those who find themselves in a modern day metaphysics seminar. These earlier philosophers worried about the nature of change, the fundamental structure of reality (and of the entities within that reality), identity, time, and so on. It is easy to look past this fact, however, because of the fundamental ontology they adhered to: for them, God, angels, and miracles were entities and phenomena that had to fit into their metaphysical systems. Just as contemporary metaphysicians work with the ontology of modern science, so too the medievals worked within their theological ontologies.
Do you guys think the shift from medievals' attitude to some theists now's near-obsession with rigorous proofs is a good thing?
