  Albo’s central contribution to the history of Jewish philosophy is his theory of principles. In his theory, he determines the fundamental, necessary beliefs that a person must uphold in order to belong to the system called “divine law.” This theory serves as an alternative to previous lists of principles, especially the thirteen principles of faith formulated by Maimonides. Albo’s list includes only three fundamental beliefs: the existence of God, the divine origin of the Torah, and reward and punishment. The following paragraphs will outline Albo’s theory and several of the prominent issues in his thought, such as the theory of law, the theory of divine attributes, the theory of human perfection and the theory of providence and reward.
