All matter is evil, and the non-material, spirit-realm is good. There is an unknowable God, who gave rise to many lesser spirit beings called Aeons. The creator of the (material) universe is not the supreme god, but an inferior spirit (the Demiurge). Gnosticism does not deal with "sin," only ignorance. To achieve salvation, one needs gnosis (knowledge). The Gnostic ideas and systems flourished in the Mediterranean world in the second century AD, in conjunction with and influenced by the early Christian movements and Middle Platonism. After the second century, a decline set in. In the Persian Empire, Gnosticism in the form of Manicheism spread as far as China, while Mandaeism is still alive in Iraq.
