Islamic Neoplatonist, centred in Baghdad. The key to understanding is the entire separation of the stable, unchanging higher world and the changing lower world. The intellect and the soul are universal and indivisible, with our souls only a part of it. God is sufficiently removed from mundane creation not to be describable or knowable at all, even negatively. To any proposition stating that God is not (e.g. caring) one must add the double negative that he is not not caring either. On the other hand, something akin to agency on the part of God creates the world.
