Dualism

Definition

Dualism is the teaching that reality rests on two first principles rather than one: good and evil, spirit and matter, light and dark. In its Gnostic forms the visible world is the work of a lesser power, not of the highest God, so matter is not fallen goodness but foreign ground.

Primary source

Behold that I am your god and beside me is none other god.

— Book of John the Evangelist (Interrogatio Iohannis), the Enoch passage, trans. M. R. James in The Apocryphal New Testament (Clarendon Press, Oxford, 1924). Open-access scan

The line is put in the mouth of the devil, instructing humanity through Enoch. That is dualism at its most compact: the claim to be the only god is spoken by the one who administers this world, not by God.

Deep Understanding

What separates dualism from an ordinary story of the fall is origin, not degree. In a monist scheme evil is damage done to something good, so the good comes first and the damage second. In a dualist scheme neither principle is derived from the other.

Historians distinguish two kinds. Under moderate (or monarchian) dualism the lesser power is itself a fallen creature who then organised matter, which is how the Secret Book tells it, with Satan as a former angel. Under absolute dualism the two principles are eternal and cannot be reduced to one another. The Bogomils are usually placed in the first group, and that distinction is what the long argument about how far their trail reaches into Europe actually turns on.

The practical consequence matters more than the classification. If the world was organised by a lesser power, its rules are not sacred by right, and obedience to them is not a virtue in itself. From there follow the three things their enemies most often report of the Bogomils: refusal of the icons, refusal of the cross, and refusal to treat the visible order as divine. The same logic sits behind the figure of the demiurge in the earlier Gnostic texts.

Often confused with

Gnosis — the knowledge that releases, where dualism is the map of the world that makes release necessary. Archon — one administrator inside the lower order, where dualism is the claim that such a lower order exists at all.

In Practice

Dualism works as a diagnostic, not as a worldview to adopt. Pick one rule you live by today without remembering when you agreed to it. Ask which order it comes from: what you know directly, or what was simply already in place when you arrived. Do not change it. Just notice which of the two it is.

In Pleroma's Words

Dualism turns dangerous the moment it stops being a map and starts being an excuse. The claim that the world was organised by a lesser power describes your position. It does not grant you permission to leave it.
