Blurb of the Mardecai M. Kaplan biography
An engaging biography that goes behind the myths to reveal the complex life of a transformative figure in modern American Judaism.
Rabbi, writer, teacher, and thinker, Mordecai M. Kaplan (1881–1983) was one of the leading Jewish personalities of twentieth-century America. Founder of the Reconstructionist movement, he was a maverick who reshaped religious faith and practice, generating controversy at every turn. Known for his relentless energy and imagination, Kaplan redefined Jewish identity, emphasizing reason over superstition, and intellectual discovery over passive inheritance. He introduced new rituals, reevaluated the role of tradition, and advocated for a Judaism that evolved with the times and fostered inclusive community.
Drawn extensively from Kaplan’s private diaries and correspondence with family and close friends, Jenna Weissman Joselit’s intimate portrait of this influential and iconoclastic thinker sheds new light on the meaning of American Judaism, identity, the limits of belonging, and the role of faith in modern society.
Jenna Weissman Joselit is the Charles E. Smith Professor of Judaic Studies and professor of history at the George Washington University. The author, most recently, of Set in Stone: America’s Embrace of the Ten Commandments, she lives in New York.
