In Platonic Mysticism, Arthur Versluis clearly and tautly argues that mysticism must be properly understood as belonging to the great tradition of Platonism. He demonstrates how mysticism was historically understood in Western philosophical and religious traditions and emphatically rejects externalist approaches to esoteric religion. Instead he develops a new theoretical-critical model for understanding mystical literature and the humanities as a whole, from philosophy and literature to art. A sequel to his Restoring Paradise, this is an audacious book that places Platonic mysticism in the context of contemporary cognitive and other approaches to the study of religion, and presents an emerging model for the new field of contemplative science.
