In his Sefer ha-'Ikkarim [Book of Principles] R. Joseph Albo discusses Maimonides' proofs for the existence of God. The following paper offers an analysis of Albo's discussion of the proofs, advancing two theses: Albo's main argument in his central discussion is that proofs for the existence of God cannot be based on the theory of the eternity of the universe. This argument, however, is contradicted by his other remarks on the topic, which appear elsewhere in the Sefer ha-'Ikkarim . Albo's (...) discussion of this issue includes several expressions of independent and critical thought. (shrink)
