 With regard to Plotinus’ contemporaries, he was sufficiently exercised by the self-proclaimed Gnostics to write a separate treatise, II 9, attacking their views. These Gnostics, mostly heretic Christians, whose voluminous and obscure writings, were only partially unearthed at Nag Hammadi in 1945 and translated in the last two decades, were sufficiently close to Platonism, but, in Plotinus’ view, so profoundly perverse in their interpretation of it, that they merited special attention. The central mistake of Gnosticism, according to Plotinus, is in thinking that Soul is ‘fallen’ and is the source of cosmic evil. As we have seen, Plotinus, although he believes that matter is evil, vociferously denies that the physical world is evil. It is only the matter that underlies the images of the eternal world that is isolated from all intelligible reality. The Gnostics ignore the structure of Platonic metaphysics and, as a result, wrongly despise this world. For Plotinus, a hallmark of ignorance of metaphysics is arrogance, the arrogance of believing that the elite or chosen possess special knowledge of the world and of human destiny. The idea of a secret elect, alone destined for salvation – which was what the Gnostics declared themselves to be – was deeply at odds with Plotinus’ rational universalism.
