Question

A. In lesson 3 on dogmatics there was an extensive discussion about formal authority and command regarding matters of faith / belief and principles, and without getting into the heart of that fascinating discussion, I was a bit surprised that it wasn’t mentioned that Maimonides explicitly writes that there is a command here as well as punishment, in the Mishneh Torah, chapter 2 of Laws of Idolatry, halakhot 2–3, and in Sefer HaMitzvot, prohibition 47, and in the principles at the beginning of the ninth principle. On the conceptual plane, Maimonides addressed this briefly at the beginning of chapter 2 of Eight Chapters, and on the face of it the discussion would have been more precise if there had been direct reference to the definitions Maimonides wrote in these places. Or perhaps that is the plan, and I need to be patient—is that so?
B. Is it correct to say that the foundations of Kant’s physico-theological proof were already written and described long before him by Saadia Gaon in the first treatise of Beliefs and Opinions (the ninth argument), and by the judge from Cordoba in Duties of the Heart, chapter 6 of the Gate of Unity?
