[Blackyce]

Demiurge is Gnostic thing not a Platonic thing, you've got it out of order. The gnostics were influencd by Plato, but, then again, so was the early church, and later, most notably, St Augustine.

[A. Pole]

Demiurge is Gnostic thing not a Platonic thing, you've got it out of order.

See the dialogue Timeous where Plato talk about Demiurge. Platonic Demiurge failed to create the perfect world - the perfect image of the perfect eternal Forms, because he has to work what is given to him - the imperfect changing matter.

"The world of Becoming, which is constantly changing, can never completely imitate the unchanging Forms which are the Models for sensory objects. The Demiurge is constrained by the materials he has to work with. Nothing in this world is Everlasting or Unchanging. Eternity (the Form) can only be imperfectly mirrored in the physical world by something which is itself changing. The Demiurge, though constrained, tries to produce the most perfect copy that he can." (See the chapter Plato's Universe of Evolution of the Concepts of Space and Time by Michael Bradie and Comer Duncan.
