لَيْسَ الْعِلْمُ عِبَارَةً عَنْ حُصُولِ صُورَةٍ مُسَاوِيَةٍ لِلْمَعْلُومِ
Knowledge is not simply the occurrence of an image identical with the known object.
If knowing always meant receiving a matching internal picture, every external change would appear to require a new picture in the knower. Even human knowledge is wider than visual imagery: relations, judgments and abstract matters are known.
The central mistake in the objection is to model divine knowledge on created mental representations.
