According to John Scotus Erigena, the nothing out of which the world is created is the divine essence.
The influence of the pseudo-Dionysian writings were transmitted to the West in the 9th century by Erigena, in whose speculative spirit both the scholasticism and the mysticism of the middle ages have their rise.
Erigena translated Dionysius into Latin along with the commentaries of Maximus, and his system is, essentially based upon theirs.
Erigena teaches the restitution of all things under the form of the Dionysian adunatio or deificatio.
In Erigena mysticism has not yet separated itself in any way from the dogma of the Church.
