Brett Yardley is a PhD candidate at KU Leuven and Marquette University, currently completing a dissertation on testimony and tradition in medieval Judaism, Islam, and Christianity.  In 2018–19, he held a Fulbright grant to conduct research in Belgium. His work shows that applying the concepts of contemporary social epistemology allows the medieval tradition to be read in a new light. Brett has recently published “Trust and Perspectivalism in the History of Epistemology: Testimony and After Certainty,” in Neo-Scolastica, and “Biblical Inspiration & Islamic Instrumental Causality: Thomas Aquinas on Prophecy and the Two Authors of Sacred Scripture,” in The Muslim World. In the Max Planck Research Group “Experience in the Premodern Sciences of Soul & Body, ca. 800–1650,” he will work on the project “Knowledge Ensouled: Premodern Experience of the Natural World,” discussing the notions of authority and the transmission of knowledge within communities via spoken and written testimony.
