For centuries, Joseph Albo’s The Book of Principles has guided seekers through the essential beliefs of Judaism. Written in the aftermath of the Disputation of Tortosa, this philosophical masterpiece distills the faith into three fundamental principles—the existence of God, divine revelation, and reward and punishment—and explores their far-reaching implications. Albo’s rational yet deeply spiritual approach offers a timeless framework for understanding the relationship between faith and reason. This modern-English edition preserves the original’s depth and clarity while rendering it in language that speaks to today’s readers. Whether you are a student of philosophy, a spiritual seeker, or simply curious about the foundations of Jewish thought, this book offers a profound and accessible journey.
