Irenaeus, Ante-Nicene Christian Library/Volume V (1868)
“ Animal substances originated from fear and from conversion; the Demiurge they also describe as owing his origin to conversion; but the existence of all the other animal substances they ascribe to fear, such as the souls of irrational animals, and of wild beasts, and men. And on this account, he (the, Demiurge) , being incapable of recognising any spiritual essences, imagined himself to be God alone, and declared through the prophets, "I am God, and besides me there is none else." [77] They further teach that the spirits of wickedness derived their origin from grief. ”
