 Marsilius criticized Ockham’s view that God’s idea coincides with creation. If this were true, Marsilius argued, the idea of producing a stone must be identical with either the stone itself, or the stone insofar as it is known by God. If the former, then God must look outside of himself in his idea, which contradicts the position of Augustine, who is quoted by Ockham. If the latter, then the idea of its production is not the stone itself, but rather God’s foreknowledge of the  stone.[30]
