This chapter argues that Jewish philosophers throughout the ages have tended toward an epistemology that might be described as “communitarian.” To that end, it explores three key notions at the heart of Jewish epistemology: knowledge by testimony, corporate knowledge, and epistemic rootedness. These notions are mined from the Hebrew Bible in conversation with Rabbinic commentaries and two great medieval philosophers, Rabbi Yehuda Halevy and Maimonides. In contemporary times, a number of philosophers have described themselves as communitarian epistemologists. This chapter argues that they might more aptly be described as communist epistemologists, and that Jewish thought is a better guide to how a communitarian epistemology might look.
