You already know the feeling. That sense that thinking, by itself, never quite gets you there. That the mind climbs and climbs, but the summit is always out of reach.
Manly P. Hall, reading Iamblichus, puts it plainly. Where Plotinus reasoned, Iamblichus prayed. Hall calls him the most devout of the Neoplatonists — not content to stop at intellect, but reaching for something higher.
Iamblichus, in his *On the Mysteries*, answers Porphyry’s doubts. He doesn’t argue for cleverness or for philosophy as an end in itself. He defends theurgy — not as Greek reasoning about the gods, but as the divine rites by which the gods themselves descend to the soul.
Hall is careful here. Theurgy isn’t magic in the vulgar sense. It isn’t about commanding spirits or chasing power. Theurgy is the “divine work.” It is the disciplined faculty, already present in man, by which the soul re-identifies with its source.
He says: “Theurgy is the instantaneous, mystical availability of the infinite.” It is where philosophy merges with religion. The mind, Hall says, is a ladder — but the ladder must finally be left behind. Reason is a servant. At some point, it must yield to a faculty superior to itself.
Theurgy, for Iamblichus and for Hall, is not about adding more thoughts or opinions. It is a simplification. Where philosophy accumulates, theurgy dissolves. It is a single, qualitative grasp of reality that ends the mind’s confusion.
Hall closes his reading of Iamblichus with a reversal. Theurgy is not a secret to be won, but a series of undoings — the reversal of all the separations that have become the burden of human life. Man is born divided. The eye sees one way, the ear hears another. He cannot focus them on one purpose.
The work is to gather these scattered parts. Not out in the world, but within. Hall says, “The primary experience arises from the unification of the diversity of his own parts.” Unity known in “the otherness” is never unity experienced. It must happen inside, or not at all.
And reason, Hall insists, cannot do this work. “Rationality is not involved, nor is knowledge regarded as the solution.” Unity is achieved “upon a level superior to the diversity.” The scattered parts cannot be assembled from inside their own confusion. They are gathered in from a higher awareness.
So the discipline is oddly passive. “To relax into the acceptance of the real.” The problem is not that man must grow more, but that he must cease to resist growth. If he stops standing in the way, the archetypes move through him.
Theurgy is the crown of philosophy, but it is not an achievement. It is the end of otherness. The moment when the mind, having built its ladder, steps aside — and lets the light come down.
