Alright, this is a total slippery slope here, but is Gorgias proclaiming an inability to be unjust now or ever? Quite the bold statement. Not knowing anything about Gorgias, did he have anything to say about objectivity within the personal narrative (sorry that sounds like an egg-head phrase, it's the best I can think of) or did he believe in absolutism? If so, he could be best friends with Ayn Rand.
