In Crescas’s opinion, we can also prove the simplicity of God, but we cannot prove the uniqueness of God. We can summarize this philosophical enquiry by saying that Crescas thinks that philosophy can prove the existence of a simple cause of the world, but it cannot arrive at the uniqueness God of the Bible. On this point Crescas comes to the conclusion that the only way to know the true essence of the divinity is to learn it from the divine revelation (the Torah and the tradition).
