Thomas Aquinas now makes a decisive step by dividing the concept of the nous poietikos in two. He identifies one part with God or the Sapientia Dei, but the other with a natural light within the soul, a lumen naturale in man.
Von Franz argues that Aquinas’s bifurcation of the nous poietikos into Sapientia Dei and lumen naturale inaugurated the split between sacred and secular knowledge that defines modernity, and simultaneously locates the figure of Sapientia Dei as a feminine creative pneuma in the Old Testament Wisdom literature.
