Hermeticism and gnosticism

In his book on the hermeticist Hegel, Magee gives this helpful sketch of the differences between gnosticism and hermeticism: “Gnosticism and Hermeticism both believe that a divine ‘spark’ is implanted in man, and that man can come to know God. However, Gnosticism involves an absolutely negative account of creation. It does not regard creation as a part of God’s being, or as ‘completing’ God [as hermeticism does]. Nor does Gnosticism hold that God somehow needs man to know Him. Hermeticism is also very often confused with Neoplatonism. Like the Hermeticists, Plotinus holds that the cosmos is a circular process of emanation from and return to the One. Unlike the Hermeticists, Plotinus does not hold that the One is completed by man’s contemplation of it.”
