In this two-volume work, Ephraim Chamiel explores questions arising from Jewish writings and the works of Jewish scholars, from the Bible to our own day. Originally published in Hebrew in three parts between 2021 and 2025, the collection examines enduring questions of faith, interpretation, Jewish law, and the relationship between tradition and modern thought.
Among the questions he considers:
- How do we reconcile the contradiction between God’s unlimited knowledge and human free will?
- Did R. Isaac Albalag adopt the doctrine of double truth, and can this doctrine help reconcile the contradictions in the book of Ecclesiastes?
- What is the source and meaning of the principles “The Torah speaks in human language” and “The Scripture does not depart from its plain meaning”?
- What meanings did the Jewish sages give throughout the generations to the terms “Torah” and derekh eretz (worldly conduct)?
- How did traditional thinkers relate to Darwin’s theory of evolution?
- Are aggadic midrashim to be taken literally? If not, what is their status in Jewish thought?
- What do Jewish sources say about women’s participation in combat and Torah study?
- Should Jewish men continue to recite the blessing “Who has not made me a woman” in the morning blessings?
Through close examination of sources and their interpretations across the generations, Chamiel reconsiders familiar readings and offers his own conclusions. The collection invites scholars, students, and interested readers to look afresh at texts and ideas central to Jewish thought and practice.
“The title of Ephraim Chamiel’s book points to what I regard as one of its most significant insights: scholarship is not simply the accumulation of knowledge, but a willingness to allow knowledge to change us. Moving between biblical and rabbinic sources, medieval philosophy, and modern Jewish thought, Chamiel traces the ways in which ideas are interpreted, challenged, reconsidered, and transformed. His close attention to the sources is joined by a willingness to remain with tensions and contradictions rather than resolve them too quickly. The Essence of Scholarship and Its Development is therefore not only a wide-ranging study of Jewish thought; it is also a reflection on the responsibility that accompanies scholarship—the responsibility to listen carefully to the voices of the past, while remaining open to reconsidering what we think we already know.”
— Prof. Hanoch Ben Pazi, Bar Ilan University
Head of Weisfeld Maayan Institute for Ethics, Jewish Philosophy and Sustainability
“Dr. Ephraim Chamiel is a special intellectual and scholar. Following a successful banking career, he immersed himself in the vast world of Jewish thought, beginning with the writings of early modern thinkers. The present volume is a treasure of methodical scholarship, touching upon scores of intriguing questions, well-known but open to interpretation of their origins and meaning both in classical and modern sources. The author, courageously ready to confront challenging issues, does not hide his liberal approach. There is no limit to renewal and vision. This fascinating volume fits this orbit.”
— Judge Elyakim Rubinstein
“Ephraim Chamiel has published a scholarly work: The Essence of Scholarship and Its Development (in 2 volumes) in Hebrew. It is now translated into English by Joshua Amaru. I have read the original Hebrew version of the book. It is learned and insightful. Ephraim raises important and challenging questions on the Biblical and Midrashic texts he analyzes. His analysis is stimulating and creative. What is unique about his scholarship is that it appeals to learned people. But it can be enjoyed by lay people who enjoy challenging questions and responses on familiar Biblical and Midrashic texts.
I use his book regularly when I study the texts that he analyzes. I love Torah study and appreciate scholars like Ephraim Chamiel who reveal original thoughts that open my eyes to ideas that I had never seen before in the text. It is a welcome addition to Biblical scholarship. Furthermore, it is particularly refreshing to note that the Rabbis of the Mishnah, the Talmud, and the Midrash (AKA ‘CHAZAL’) studied these texts as well. Their comments are worthy of both clarification and analysis. Ephraim’s work adds clarity and new dimensions to the MIDRASHIC scholarship of ‘CHAZAL’.”
— Rabbi Heshie Billet
“Ephraim Chamiel’s comprehensive work is a wide-ranging and diverse scholarly and philosophical journey, displaying the remarkable skill of a critical scholar of Jewish thought who is socially and spiritually engaged with his subjects. It is a compelling journey through the history of such themes as prophecy and free will, evolution, women and Jewish law, and Torah from Sinai. Throughout, Chamiel exposes the gap between a text’s plain meaning and the interpretive transformations shaped by time, place, and the interpreter’s worldview.
These volumes display intellectual breadth, scholarly integrity, engagement with contemporary concerns, direct normative judgment about what ought to be, and an intellectual humility grounded in Chamiel’s philosophy of ‘dual truth,’ which he develops following Shadal—from whom he also draws the principles of intellectual honesty, willingness to revise, and openness to truth.
This is a learned, morally engaged, personal, and thought-provoking work.”
