Oxford Studies in Medieval Philosophy annually collects the best current work in the field of medieval philosophy. The various volumes print original essays, reviews, critical discussions, and editions of texts. The aim is to contribute to an understanding of the full range of themes and problems in all aspects of the field, from late antiquity into the Renaissance, and extending over the Jewish, Islamic, and Christian traditions. Volume 9 ranges widely over this terrain, including Mark Kalderon on Augustine’s theory of perception, Alexander Lamprakis on belief in miracles among Baghdad Christian philosophers, Andreas Lammer on Avicenna on time, Ana María Mora-Márquez on logical methodology, Franziska van Buren on Bonaventure’s theory of universals, Eric Hagedorn on Ockham’s divine-command theory, and Dominik Perler on exemplar causes in Suárez.
