  In addition to many other changes from Plotinus and the Theology of Aristotle, one special point of difference is the reference here to universal matter (see section 5). It is precisely Ibn Gabirol's unique focus on “universal matter” (a grade of spiritual materiality at the very core of existence) which leads him to uniquely envision the ultimate moment of Neoplatonic return as a moment of “illuminated shadow”: since there is a material element just “above” Intellect for Ibn Gabirol, the return to Intellect will be characterized by the light of Wisdom set within the shade of the supernal first matter.
