The Road Up and Down Are One and the Same

Most of the evidence that we have about heraclitus philosophy is in the form of what i was calling one liner. It seems to me that there's a great deal more to be said about it than that. So you might think that when he says the road up and the road down are one and the same, it's jus supposed to be a doctrine. And the doctrine would be something like everythingis one or something. But supposing you imagine not just somebody announcing that as a philosophical principle, but supposing he thinks quite hard when he says whatever it is he says about his audience. I think it's much more argumentative.
