Abraham Joshua Heschel (1907-1972) was one of the twentieth century's most influential Jewish thinkers, a respected theologian and enthusiastic civil rights activist who marched to Selma with Martin Luther King, Jr. His theology emphasized the immediacy of wonder and awe, yet his writing was studded with signs of his vast knowledge of traditional scholarship. No other Jewish thinker of note in the twentieth century used such a wide range of texts so extensively.

Abraham Joshua Heschel and the Sources of Wonder is the first book to demonstrate how Heschel's political, intellectual, and spiritual commitments were embedded in his reading of Jewish tradition. By shedding new light on how Heschel's theological project reconciled the demands of tradition and the modern world, Michael Marmur offers an inspirational lesson in how contemporary Jewish thought can embrace both the texts of the past and the challenges of the present.
