Abraham Joshua Heschel was a singular figure in American Jewish history and, indeed, in Jewish thought. Born in 1907 and reared in the world of Polish Hasidim, Heschel studied philosophy and Biblical criticism in Berlin before becoming a pivotal figure in American Jewish and non- Jewish religious life, galvanizing Americans on issues of social justice. The conditions that produced a figure capable of such depth and breadth of traditional Jewish learning and secular studies seem no longer possible in our age, focused as it is on hyper-specialization. Heschel shared a vision of Judaism at once profoundly rooted in tradition and simultaneously subversive of the status quo. He offered a vision of Judaism that did not espouse separation from the larger society but rather demanded critical engagement with it. His theological commitments undergirded his courageous, outspoken efforts on behalf of the Civil Rights Movement, his protests against the war in Vietnam, and his work to improve Jewish and Christian relations. Given the singularity of his vision and the strength of his character, it should not be surprising that -- nearly four decades after his death -- his legacy remains towering and majestic in the consciousness of the American Jewish community and beyond.
