ABRABANEL’S TREATISE ON THE PRINCIPLES OF FAITH

Don Isaac Abrabanel's ostensible aim in writing Rosh Amanah was to defend Maimonides' philosophy from the attacks of its critics, notably Hasdai Crescas and Joseph Albo, and it contains the most exhaustive and systematic analysis of the thirteen principles ever written. After twenty-two chapters of sustained and zealous defense of Maimonides, Abrabanel reached the conclusion that Judaism in fact, has no dogmas whatsoever, since all its beliefs are equally valid, fundamental, and precious.
