"By republishing the classic (and, in fact, publishing the Stone commentary for the first time), JPS has resurrected one of Judaism's great books. This should be the first of a series. Thank you, JPS and Rabbi Stone."—CJ Magazine "This translation, published originally in 1936 by JPS, is a landmark in Jewish publishing. It made this Hebrew text finally available to English readers, and it gave us insights into the groundbreaking work that Kaplan did in orienting American Jews to the deep connection between ethical living and religious belief. It is no wonder that this book has become the centerpiece of the modern-day Mussar Movement, which inspires so many on their spiritual path."—Jewish Media Review "Readers will find Stone’s ideas thought-provoking."-Jewish Eye "Ira Stone has breathed new life into this classic of Jewish ethical literature. His introduction places Mesillat Yesharim and Kaplan's translation of it in their proper historical and philosophical contexts. His running commentary to Luzzatto's text is lucid and informative, helping contemporary readers discover how this influential work can continue to guide and inspire us today."—Louis E. Newman, John M. and Elizabeth W. Musser Professor of Religious Studies and Humphrey Doermann Professor of Liberal Learning, Carleton College "Readers with an interest in rabbinic thought, Jewish philosophy, and Jewish ethics will find much to engage them. Stone provides the tools for the reader to easily and independently access Luzzatto's great classic."—Jewish Book World
