The philosophy of Plotinus is an account of an ordered structure of living reality, which proceeds eternally from its transcendent First Principle, the One or Good, and descends in an unbroken succession of stages from the Divine Intellect and the Forms therein through Soul
Edinger frames Plotinus’s entire metaphysical system as a naive precursor to Jung’s psychology of the Self, mapping the procession-and-return structure onto individuating psychic movement.
