Exploring the first-person narratives of three figures from the Christian, Jewish, and Islamic mystical traditions - St. Teresa of Avila, Rabbi Dov Baer, and Ruzbihan Baqli, Anthony J.Steinbock provides a full phenomenology of mysticism based in the Abrahamic religious traditions. Steinbock relates a broad range of religious experiences, or verticality, to the many philosophical problems of evidence, selfhood, and otherness. From this philosophical description of vertical experience, Steinbock develops a social and cultural critique in terms of idolatry - as pride, secularism, and fundamentalism - and suggests that contemporary understandings of human experience must come from a fuller, more open view of religious experience. This careful study will interest all readers of philosophy and religion.
