 Isaac not only wished to do away with astral decrees, but he also wished to do away with God’s knowledge and His decrees concerning all accidental and possible things. Because of this, he said in his book that we ought not to believe in any way that such things can be known, or observed by any knower, before they exist. Hence he implied that they cannot be known nor observed by God. (Minḥat Qenaot, Chapter 2)
